Operation and maintenance of belt dryer

Operation and maintenance of the belt dryer 1. The drying efficiency of the belt dryer depends largely on the quality of the combustion chamber. Therefore, during the operation of the belt dryer, the combustion chamber, blower and dust must be removed. Pay special attention to the vacuuming equipment.

2. Ignite the furnace one hour before starting the belt dryer. Check all the auxiliary equipment, including the transmission parts of the dryer, the towing part, etc., all of which should be fastened, normal, slippery and reliable before driving.

(1) Before igniting the furnace, the furnace, furnace raft, feeding device, combustion chamber, slag in the pit, furnace door, air duct, regulating valve and blower, dust collector, etc. should be inspected.

(2) Before starting the belt dryer, check the fuel, tools and transmission support device to lubricate all the bearings and friction surfaces.

(3) The step of starting the belt dryer is to start the belt dryer motor first, then start to transport the wet material equipment, and then start the dry material conveying equipment to form a continuous and uniform operation procedure.

3. During the operation of the belt dryer, the temperature of each part of the bearing should be checked frequently. The temperature should not exceed 50 °C, the gear sound response should be stable, and the transmission, support and cylinder rotation should have no obvious impact, vibration and transmission. Always check, maintain and maintain the equipment. The contents should include:

(1) All bolt fasteners should not be loose.

(2) Always pay attention to the contact between the rolling ring and the retaining wheel and the tug.

(3) The windshield, the gear cover shall not have cracks and frictional damage.

(4) All parts should be properly lubricated according to the following table. Lubrication point: lubricating material lubrication time and cycle motor soda lime grease for 6 months; reducer bearing calcium base grease for 6 months; reducer gear 10# oil change / 3 months; drive bearing calcium base grease 2 times / shift; Support bearing sodium calcium grease for 6 months; retaining wheel bearing sodium calcium grease 6 months 5

Belt dryer failure and elimination

1. The moisture content of the dried material is greater than the specified value, and the elimination method is to control the production capacity of the belt dryer and increase or decrease the supply of heat;

2. The rolling ring has a swing on the cylinder running. The reason is that the side of the concave joint of the rolling ring is not clamped. The elimination method is to use the pad to keep the rolling ring and the concave joint evenly and properly clamped to prevent overtightening and easy. have an accident;

3. The meshing clearance between the large gear and the pinion is broken. The reason is: a. the tug wear b. the wheel wear c. the pinion wear is eliminated by turning or replacing according to the wear condition, or it can be installed in reverse or in pairs. ;

4, the whole body vibration, the reason is a. The connection between the tug device and the base is broken, the elimination method is to correct the fastening connection part, so that it is in the correct position;

5. The side of the rolling ring is worn out. The elimination method is to turn or replace the rolling ring according to the degree of wear.

Nasopharyngeal Swab

Nasopharyngeal swabs are actually long cotton swabs, similar to long sterile cotton swabs, and their main function is to take nasopharyngeal secretions for Bacterial Culture and drug sensitivity tests. Bacterial culture and drug sensitivity test are used to select and clarify the source of infection in the nasopharynx and microorganisms in the nasopharynx, and then drug sensitivity test can be done to determine which drugs are sensitive, so that sensitive drugs can be selected for treatment, so as to achieve better results Therefore, the nasopharyngeal Swab is actually a cotton swab for tissue.
