Description

Technical Field

[0001] This utility model relates to a dust recovery device for a production line, belonging to the field of workshop dust treatment technology. Background Technology

[0002] During the material feeding process on the production line, when powdery materials are added to sealed tanks such as mixing tanks and blending tanks, the material rushing into the sealed tank creates an impact airflow. This airflow carries the powdery material back out of the tank through the feeding port, forming dust. Some dust is toxic, affecting the health of operators and the workshop production environment; some dust is explosive, posing a safety risk if suspended in the production area. The dust that escapes from the tank is the material lost during feeding, resulting in raw material waste, reduced material yield, and impact on production costs.

[0003] Therefore, there is an urgent need for a production line dust recovery device that can effectively recover backflushing dust during tank feeding, suppress dust generation during the feeding process, recover powder to save raw materials, improve yield, and reduce production costs. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a dust recovery device for a production line. When feeding materials into the tank, it can effectively recover backflushing dust, suppress the generation of dust during the feeding process, save raw materials by recovering powder, improve the yield, and reduce production costs.

[0005] The purpose of this utility model is achieved as follows:

[0006] A dust recovery device for a production line includes a tank with a feeding port at the top, and an air intake at the top of the tank away from the feeding port. The air intake is connected to a dust collection mechanism and an induced draft fan via pipelines. The dust collection mechanism includes a box with a support at the bottom, a dust collector bag and a pulse back-blowing device disposed inside the box, and a conical discharge port disposed at the bottom of the box. An air inlet connected to the air intake is disposed on the conical side of the discharge port, and an air outlet connected to the induced draft fan is disposed on the upper part of the box. The dust collector bag is disposed in the middle of the box. The pulse back-blowing device is disposed above the dust collector bag and sprays pulsed compressed air onto the dust collector bag.

[0007] Furthermore, the air intake and the feeding port are mirror images of each other, located at both ends of the top of the tank.

[0008] Furthermore, the pulse backflushing device includes an air tank fixed to the outer side of the housing, multiple sets of parallel backflushing air pipes connected to the air tank and extending into the housing above the dust collector bag; multiple sets of nozzles for spraying pulse gas onto the dust collector bag are provided on the backflushing air pipes, and each backflushing air pipe is equipped with a solenoid valve, whose opening and closing frequency is controlled by a controller located on the outside of the housing to control the backflushing pulse rhythm.

[0009] Furthermore, the air storage tank is connected to a compressed air source.

[0010] Furthermore, the discharge port is equipped with a discharge valve for convenient unloading.

[0011] Furthermore, a silencer is installed at the air outlet of the induced draft fan.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features an air intake at the top of the tank, opposite the feeding port. A blower and a dust collection mechanism create negative pressure at the air intake, rapidly drawing the impact airflow from inside the tank to the dust collection mechanism. The dust collection mechanism then adsorbs and recovers the dust from the powder, effectively suppressing the generation and spread of dust during feeding, saving raw materials, increasing material yield, and reducing production costs.

[0019] See Figures 1-2 This utility model relates to a dust recovery device for a production line, comprising a tank 1 with a feeding port 2 at the top, and a suction port 3 at the top of the tank 1 away from the feeding port 2. When material is fed into the tank 1 through the feeding port 2, the impact airflow formed by the material rushing into the tank 1 moves along the feeding direction and encounters the inner wall of the tank 1, forming a backflow airflow that carries a large amount of material, forming dust. Therefore, by symmetrically positioning the suction port 3 and the feeding port 2 at both ends of the top of the tank 1, the impact airflow can be quickly guided out of the tank 1 along the direction of the impact airflow, avoiding repeated impacts and rebounds within the tank 1 that generate more dust, thus reducing the amount of dust generated and the workload of subsequent dust collection.

[0020] The air intake 3 is connected to the dust collection mechanism 4 and the induced draft fan 5 in sequence through pipelines; the exhaust port of the induced draft fan 5 is equipped with a silencer 6 to reduce operating noise; the dust collection mechanism 4 includes a box 41 with a support 44 at the bottom, a dust collection bag 42 and a pulse back-blowing device set inside the box 41, and a conical discharge port 43 set at the bottom of the box 41; the conical side of the discharge port 43 is provided with an air inlet connected to the air intake 3, and the upper part of the box 41 is provided with an air outlet connected to the induced draft fan 5; the dust collection bag 42 is set in the middle of the box 41; the bottom of the discharge port 43 is equipped with a discharge valve to facilitate unloading and recycling of materials, saving production costs;

[0021] The pulse back-blowing device is located above the dust collector bag 42 and includes an air tank 45 fixed to the outer side of the housing 41, and multiple sets of parallel back-blowing air pipes 46 connected to the air tank 45 and extending into the housing 41 above the dust collector bag 42. Multiple sets of nozzles 47 are provided on the back-blowing air pipes 46 to spray pulsed gas onto the dust collector bag 42. Each back-blowing air pipe 46 is equipped with a solenoid valve 48, whose opening and closing frequency is controlled by a controller 49 located outside the housing 41 to control the back-blowing pulse rhythm. The air tank 45 is connected to a compressed air source. The controller 49 controls the opening and closing speed of the solenoid valve 48 based on the pressure difference between the air inlet and outlet of the dust collection mechanism 4, controlling the nozzles 47 to spray pulsed compressed air onto the dust collector bag 42, preventing the bag from becoming clogged and ensuring normal dust collection operation.

[0022] During production, the induced draft fan 5 is started first, and a negative pressure is formed at the suction port 3 opposite to the feeding port 2 of the tank 1. Material is fed into the feeding port 2 of the tank 1. The impact airflow generated by the material entering the tank 1 is directly guided into the dust collection mechanism 4 by the suction port 3, which avoids the airflow hitting the inner wall of the tank 1 multiple times and bringing out more dust. The dust collection mechanism 4 filters the dust through the dust collector bag 42, causing it to settle and be recycled into the discharge port 43. The filtered gas is discharged by the induced draft fan 5, thereby achieving the purpose of suppressing dust, recovering powder to save raw materials, improving material yield, and reducing production costs.

[0023] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
