Abstract
Description
Technical Field
[0001] This utility model relates to a dust removal device for food additive production, belonging to the technical field of dust removal devices. Background Technology
[0002] Food additives are artificial or natural substances added to food to improve its quality, color, aroma, and flavor, as well as for preservation, freshness, and processing needs. They play a crucial role in the food industry. The first step in food additive production involves manually feeding solid powdered raw materials (such as starch, sugar powder, salt, and spices) into equipment (e.g., silos, crushers). Due to the drop or tilting motion of the material, a large amount of dust is stirred up. This dust spreads throughout the workshop, posing a health risk to workers and potentially leading to safety accidents such as dust explosions. Furthermore, the dust cannot be collected and reused, resulting in waste. Utility Model Content
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a dust removal device for food additive production, which is used to collect dust generated when raw materials are fed, to prevent dust from spreading in the workshop and to eliminate safety hazards.
[0004] The dust removal device for food additive production of this utility model includes a dust removal host. The outer shell of the dust removal host is provided with a feeding port and a discharging port. The discharging port is sealed to one end of a screw conveyor, and the other end of the screw conveyor is sealed to subsequent processing equipment. A filter element is installed inside the dust removal host, and a centrifugal fan is connected to the top of the dust removal host. A tilting device is installed on one side of the dust removal host, which is used to pour the raw materials in the raw material packaging bag into the dust removal host. The tilting device includes a fixed plate, a tilting plate, a motor, and a lead screw.
[0005] The technical solution of this utility model is to provide a dust removal device for food additive production. When in use, the raw material packaging bag is opened and placed on the tilting device. The raw material powder is poured into the dust removal host through the tilting device.

The two sides of the lead screw nut are hinged to the tilting plate through connecting rods. When the lead screw nut moves on the lead screw, the lead screw nut pushes the tilting plate to rotate around the hinge point between the tilting plate and the fixed plate through the connecting rods.
[0007] Furthermore, a quick clamp is fixed to the top surface of the tilting plate to clamp the rear end of the raw material packaging bag, and a limit block is installed on the bottom surface of the tilting plate.
[0008] Preferably, the dust collector is equipped with a tube sheet inside, the filter element is detachably connected to the tube sheet, and the position on the tube sheet where the filter element is installed is provided with an opening for airflow to pass through.
[0009] Furthermore, a blowpipe is fixed above the tube sheet, and one side of the blowpipe is connected to a pulse solenoid valve; a backflush nozzle is installed on the blowpipe, which extends into the filter element and is located at the center of the filter element.

[0020] The present invention will be further described below with reference to specific embodiments.
[0021] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.
[0022] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.
[0023] like Figures 1-6 As shown, this embodiment is achieved through the following technical solution: It includes a dust collector, the outer casing 3 of which is provided with a feeding port 23 and a discharge port 22. The discharge port 22 is sealed to one end of a screw conveyor 5, and the other end of the screw conveyor 5 is sealed to subsequent processing equipment. A filter element 9 is installed inside the dust collector; the filter element 9 is a filter cartridge with a sealed bottom and an open top. A centrifugal fan 1 is connected to the top of the dust collector. A tilting device 4 is installed on one side of the dust collector, used to pour the raw materials from the raw material packaging bag into the dust collector. The tilting device 4 includes a fixed plate 17, a tilting plate 12, a motor 18, and a lead screw 16.
[0024] In this embodiment, one end of the fixed plate 17 is hinged to one end of the tilting plate 12. The motor 18 is fixedly mounted on the fixed plate 17. The lead screw 16 is rotatably connected to the fixed plate 17 through the bearing seat 19. One end of the lead screw 16 is drive-connected to the motor 18. A lead screw nut 20 is threadedly connected to the lead screw 16. Both sides of the lead screw nut 20 are hinged to the tilting plate 12 through connecting rods 14. When the lead screw nut 20 moves on the lead screw 16, the lead screw nut 20 pushes the tilting plate 12 to rotate around the hinge point between the tilting plate 12 and the fixed plate 17 through the connecting rods 14. A quick clamp 13 is fixed on the top surface of the tilting plate 12 to clamp the rear end of the raw material packaging bag. A limit block 15 is installed on the bottom surface of the tilting plate 12.
[0025] The dust collector has a tube sheet 10 inside, and the filter element 9 is detachably connected to the tube sheet 10. The tube sheet 10 has an opening for airflow at the position where the filter element 9 is installed. A blowpipe 8 is fixed above the tube sheet 10, and one side of the blowpipe 8 is connected to a pulse solenoid valve 2. A back-blowing nozzle is installed on the blowpipe 8, which extends into the filter element 9 and is located at the center of the filter element 9.
[0026] The dust collector is also equipped with a detachable sealing plate 6. The outer shell 3 of the dust collector is provided with a limiting strip 21. The limiting strip 21 is located on both sides of the feeding port 23. The limiting strip 21 is adapted to the sealing plate 6. The sealing plate 6 can be inserted into the limiting strip 21 to block the feeding port 23.
[0027] The outer casing 3 is detachably connected to a maintenance cover 11. After removing the maintenance cover 11, the inside of the dust collector can be inspected. The outer casing 3 is also equipped with a control switch 7, which is used to control the start and stop of the centrifugal fan 1 and the pulse solenoid valve 2, and the forward and reverse operation of the motor 18.
[0028] The method of using this utility model is as follows:
[0029] 1. After opening the raw material packaging bag, place it on the tilting plate 12 and use the quick clamps 13 to press the rear end of the packaging bag to prevent it from moving;
[0030] 2. Start the centrifugal fan 1. Under the suction of the centrifugal fan 1, a negative pressure is formed inside the dust collector. At this time, control the motor 18 to rotate the tilting plate 12, and slowly pour the raw materials in the packaging bag into the dust collector.
[0031] 3. Most of the raw material powder enters the screw conveyor 5 through the discharge port 22, and is then transported by the screw conveyor 5 to the subsequent processing equipment;
[0032] 4. The dust raised is drawn towards the filter element 9 under negative pressure, intercepted by the filter element 9, and adheres to the surface of the filter element 9. The clean air is then discharged to the atmosphere through the centrifugal fan 1.
[0033] 5. When the surface of the filter element 9 is clogged with dust and the permeability is reduced, turn off the centrifugal fan 1 and seal the feed port 23 with the sealing plate 6. Then start the pulse solenoid valve 2 to backflush the filter element 9, so that the dust intercepted on the surface of the filter element 9 falls below and enters the screw conveyor 5 to participate in production.
