Description

Technical Field

[0001] This utility model belongs to the field of industrial dust removal technology, specifically relating to a dust collector for dryers. Background Technology

[0002] In industrial production, dryers are key equipment in the food, chemical, pharmaceutical, and textile industries, used to remove moisture or solvents from materials. However, during the drying process, the materials are easily subjected to heat volatilization, crushing, or airflow impact, generating large amounts of dust and aerosol particles. These particles are complex in composition and possess adhesiveness, high temperature, and even explosion risks. If not effectively treated, these particles will be directly emitted into the atmosphere, causing environmental pollution, threatening worker health, and increasing material losses and production safety hazards.

[0003] Traditional dust removal technologies (such as bag filters) have significant limitations in drying scenarios: the dust falling into the dust collector hopper may be moist, and moist dust is not easy to be discharged. Wet dust tends to adhere to the dust collector hopper, affecting the dust removal process. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing equipment is unable to effectively remove damp dust from the dust collector hopper, and wet dust tends to adhere to the dust collector hopper, affecting the dust removal process.

[0005] The technical solution adopted to solve the above-mentioned technical problems is to provide a dust collector for the dryer.

[0006] Furthermore, the dust collector includes a dust collection box body, with a connecting flange fixedly connected to the bottom of the dust collection box body. A dust collector hopper is fixedly connected to the bottom of the connecting flange. An electric telescopic rod is fixedly connected to the inner top surface of the dust collector hopper. A rotary sprayer is fixedly connected to the bottom end of the electric telescopic rod. An air supply pipe is fixedly connected to the left side of the top surface of the rotary sprayer.

[0007] Furthermore, a protective device is fixedly connected to the top surface of the dust collector box, and several electromagnetic pulse valves are fixedly connected to the top front of the dust collector box. Each electromagnetic pulse valve is fixedly connected to an air storage tank at its bottom end. The air storage tank and the air supply pipe are fixedly connected. A perforated plate is provided below the air storage tank, and a blowpipe is provided on the front of the electromagnetic pulse valve.

[0008] The above technical solution uses the electromagnetic pulse valve and the air storage tank to clean the dust collector bags. The high-pressure gas in the air storage tank is then transported to the rotary sprayer through the air supply pipe to blow the dust collector hopper, making the cleaning work more thorough and effectively preventing dust from adhering to the dust collector hopper.

[0009] Further, a dust collector air inlet is provided on the right side of the dust removal box body, and a dust collector air outlet is provided on the left side of the dust removal box body. A plurality of cylinders and lift valves are fixedly connected to the rear side of the top surface of the dust removal box body. An air duct inclined plate is provided inside the dust removal box body, and the air duct inclined plate is correspondingly arranged with the dust collector air inlet and the dust collector air outlet.

[0010] Further, a dust removal skeleton is fixedly connected to the right side of the dust removal box body. The dust removal skeleton is located on the front side of the dust collector air inlet. A dust removal cloth bag is provided outside the dust removal skeleton, and the dust removal cloth bag is correspondingly arranged with the blowpipe. A plurality of dust collector top door covers are provided on the top surface of the dust removal box body.

[0011] Further, a dust collector support is provided outside the dust collector ash hopper. The dust collector support is fixedly connected to the dust removal box body. A ash hopper inspection door is provided at the bottom of the front of the dust collector ash hopper, and a single weight hammer flap valve is fixedly connected to the bottom of the ash hopper inspection door.

[0012] Through the above technical solution, the dusty gas enters the dust removal box body through the dust collector air inlet and is distributed to each filter chamber by the air inlet pipe. When the dusty gas passes through the dust removal cloth bag, the dust is intercepted on the outer surface of the dust removal cloth bag, and the clean gas passes through the dust removal cloth bag and enters the clean gas chamber and is discharged through the dust collector air outlet. The electromagnetic pulse valve is instantaneously released, and the high-pressure air flow is introduced into the inside of the dust removal cloth bag through the blowpipe via the venturi tube. The high-pressure air flow causes the dust removal cloth bag to expand sharply, and the dust layer attached to the surface falls off due to inertia, completing the dust cleaning work.

[0013] The beneficial effects of the present utility model are as follows:

[0014] In the present utility model, an electromagnetic pulse valve and an air storage tank are provided on the front surface of the dust removal box body, an electric telescopic rod is provided inside the dust collector ash hopper, a rotary sprayer is provided at the bottom end of the electric telescopic rod. The dust cleaning work of the dust removal cloth bag is completed through the cooperation of the electromagnetic pulse valve and the air storage tank, and the high-pressure gas in the air storage tank is transported to the rotary sprayer through the air delivery pipe, so that it blows the dust collector ash hopper, making the dust cleaning work more thorough and effectively preventing dust from adhering to the dust collector ash hopper.

Specific embodiments

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] As Figures 1-5 shown, the dust collector supporting the dryer includes a dust removal box body 6. Connecting flanges 7 are fixedly connected to the lower sides of the dust removal box body 6. A dust collector hopper 9 is fixedly connected to the lower side of the connecting flange 7. The dust collector hopper 9 is used to receive the dust falling from the dust removal box body 6. A dust collector support is provided outside the dust collector hopper 9. The dust collector support 12 is fixedly connected to the dust removal box body 6. A hopper inspection door 10 is provided at the bottom of the front of the dust collector hopper 9. The hopper inspection door 10 is used to inspect the inside of the dust collector hopper 9. A single-weight hammer flap valve 11 is fixedly connected to the bottom of the hopper inspection door 10. The single-weight hammer flap valve ll is used to close and clean the dust in the dust collector hopper 9. An electric telescopic rod 8 is fixedly connected to the inner top surface of the dust collector hopper 9. The electric telescopic rod 8 is used to drive the rotary sprayer 13 to move up and down. The bottom end of the electric telescopic rod 8 is fixedly connected to the rotary sprayer 13. The rotary sprayer 13 is used to blow the dust collector hopper 9 to make the dust cleaning work more thorough. A gas transmission pipe 21 is fixedly connected to the left side of the top surface of the rotary sprayer 13. A dust removal skeleton 18 is fixedly connected to the right side of the dust removal box body 6. The dust removal skeleton 18 is located in front of the air inlet 19 of the dust collector. A dust removal filter bag 17 is provided outside the dust removal skeleton 18. The dust removal filter bag 17 is arranged corresponding to the blowing pipe 16.

[0023] The top surface of the dust collector box 6 is provided with several dust collector top covers 14. The right side of the dust collector box 6 is provided with a dust collector air inlet 19, and the left side of the dust collector box 6 is provided with a dust collector air outlet 20. Several cylinders and lifting valves 15 are fixedly connected to the rear side of the top surface of the dust collector box 6. The interior of the dust collector box 6 is provided with an air duct inclined plate 5, which is correspondingly set with the dust collector air inlet 19 and the dust collector air outlet 20. A protective device 1 is fixedly connected to the top surface of the dust collector box 6. Several electromagnetic pulse valves 2 are fixedly connected to the top front of the dust collector box 6. An air storage tank 3 is fixedly connected to the bottom of each electromagnetic pulse valve 2. The electromagnetic pulse valves 2 and the air storage tank 3 are used to cooperate with the blow pipe 16 to clean the dust in the dust collector bag 17. The air storage tank 3 is fixedly connected to the air supply pipe 21. A perforated plate 4 is provided below the air storage tank 3. The blow pipe 16 is provided on the front of the electromagnetic pulse valve 2.

[0024] The working principle of this embodiment is as follows: During filtration, the dust-laden gas enters the dust collector housing 6 through the dust collector inlet 19 and is distributed to each filter chamber by the air inlet pipe. When the dust-laden gas passes through the dust collector bag 17, the dust is trapped on the outer surface of the dust collector bag 17, and the clean gas passes through the dust collector bag 17 into the clean air chamber and is discharged through the dust collector outlet 20. As the dust layer thickens, the pressure difference between the inside and outside of the dust collector bag 17 gradually increases.

[0025] When the differential pressure reaches the set value or the preset cleaning cycle is reached, the system starts the offline cleaning process, closes the inlet and outlet valves of the target cleaning chamber through the PLC, cuts off the airflow, and stops the filtration of the chamber. Compressed air in the air reservoir 3 is released instantaneously through the electromagnetic pulse valve 2 and introduced into the dust collector bag 17 through the blowpipe 16 and venturi tube. The high-pressure airflow causes the dust collector bag 17 to expand rapidly, and the dust layer attached to the surface falls off due to inertia. The cleaning time is extremely short, avoiding excessive cleaning and damage to the dust collector bag 17. The fallen dust falls into the dust collector hopper 9 and is discharged through the ash discharge device. During ash discharge, the electric telescopic rod 8 drives the rotary sprayer 13 to move up and down, and the high-pressure gas in the air reservoir 3 is transported to the rotary sprayer 13 through the air supply pipe 21, so that it blows the dust collector hopper 9, making the cleaning work more thorough and effectively preventing dust from adhering to the dust collector hopper 9. After the cleaning is completed, the valve is reopened, and the chamber returns to the online filtration state. The system sequentially performs offline cleaning of each chamber to ensure continuous operation of the entire dust collector without downtime.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
