Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments of the present utility model and the features in the embodiments can be combined with each other in the absence of conflict.

[0035] According to the concept of this application, Figures 1 to 3 To describe an embodiment of a material conveying and dust removal device for removing dust from materials. Specifically, the material conveying and dust removal device is constructed as an integrated structure, which has three components: a dust removal box 1, a ventilation baffle 5, and a circulation filter unit 11. Through the mutual cooperation of the dust removal box 1, the material diverter plate 9, the ventilation baffle 5 and other structures, the material can be double-dusted during use, effectively ensuring the dust removal effect, and the circulation filter unit 11 can also be used to filter the dust while continuously blowing fresh air into the dust removal fan 114 to form a circulation dust removal effect. The overall structure of the device is compact, the operation is simple, the dust removal efficiency is high, and it is suitable for small-batch loading scenarios.

[0036] Combine Figure 1-Figure 3 As shown, the utility model provides a material conveying and dust removal device, comprising:

[0037] The dust collecting box body 1 has a feeding pipe 2 installed at the top center of the dust collecting box body 1, a dust collecting hood 3 is fixedly connected to the top of the dust collecting box body 1, the dust collecting hood 3 and the dust collecting box body 1 are connected to each other, and a transition box 4 is fixedly connected to one side of the dust collecting hood 3;

[0038] The ventilation baffle 5 is fixed obliquely to the bottom of the inner wall of the dust removal box 1. The front end surface of the ventilation baffle 5 abuts against the front door panel 13 of the dust removal box 1. The rear end surface of the ventilation baffle 5 is fixedly connected to the baffle 6. The ventilation baffle 5 and the baffle 6 divide the space inside the dust removal box into a material channel portion 7 and an air supply transition portion 8. A material diverter plate 9 is installed in the material channel portion 7. The material diverter plate 9 is fixed to the side wall of the baffle 6, and an air inlet hole 10 is opened in the center of the baffle 6.

[0039] The circulating filter unit 11 has an air inlet connected to the transition box 4 and an air outlet connected to the side wall of the dust removal box 1 , and is used to transport fresh air to the material channel portion 7 and the air supply transition portion 8 after dust removal of the material.

[0040] It should be noted that the front door panel 13 of the dust removal box 1 refers to the door panel on the side away from the circulation filter unit 11 when the staff operates it, and the front end described in this embodiment refers to the end close to the front door panel 13, and the rear end refers to the end away from the front door panel 13.

[0041] According to the technical solution of this embodiment, a discharge pipe 12 is installed at the bottom end of the dust removal box 1. The discharge pipe 12 is used to discharge the dust-removed material out of the dust removal box 1 for the next operation.

[0042] According to the technical solution of this embodiment, there are two dust hoods 3, which are respectively located on both sides of the feed pipe 2, and the two dust hoods are interconnected with the transition box 4. The provided dust hoods facilitate the adsorption of dust in the dust removal box body 1 and suck the dust into the dust hood and the transition box 4.

[0043] According to the technical solution of this embodiment, there are two ventilation baffles 5, and the two ventilation baffles 5 are symmetrically arranged with the center of the dust removal box 1 on the left and right, and ventilation holes are opened on the side walls of the two ventilation baffles 5. The diameter of the ventilation holes is smaller than the particle size of the material. The set ventilation holes facilitate the air flow entering the ventilation baffle 5 to blow up the dust in the material without causing the material to pass through.

[0044] Furthermore, the top opening of the discharge pipe 12 is located at the bottom of the inclined ventilation partition 5. After the material is dusted, it will fall along the inclined ventilation partition 5 under the action of gravity, then fall to the bottom and be discharged from the dust removal box 1 along the discharge pipe 12.

[0045] According to the technical solution of this embodiment, the front door panel 13 of the dust removal box 1 is rotatably connected to the dust removal box 1, and the front end of the material diversion plate 9 also abuts against the side wall of the front door panel 13. Opening the front door panel 13 makes it convenient for the staff to maintain the interior of the dust removal box 1. It should be noted that the front door panel 13 can be made of transparent material, which makes it convenient for the staff to observe the dust removal status of the material inside the dust removal box 1 in time.

[0046] According to the technical solution of this embodiment, the material diversion plate 9 is made of six plates connected end to end. The top and bottom of the material diversion plate 9 are both set to be inclined, and the inclined surface is high in the middle and gradually decreases towards the sides. A ridge is formed in the middle of the inclined surface to facilitate the diversion of the falling material and facilitate the natural rolling down of the material. The air inlet 10 is located inside the material diversion plate 9. Ventilation holes are opened on the side walls of the material diversion plate 9. The diameter of the ventilation holes is smaller than the particle size of the material. When the air flow blows into the interior of the material diversion plate 9 from the air inlet 10, the air flow will pass through the ventilation holes and blow up the dust in the material from the inside to the outside. At this time, the dust can be sucked away in conjunction with the dust hood 3, thereby forming the first dust removal.

[0047] According to the technical solution of this embodiment, the circulating filter unit 11 includes an exhaust pipe 111 fixedly connected to the side wall of the transition box 4, a cyclone separator 112 is installed below the exhaust pipe 111, a filter cartridge 113 is connected to the side wall of the cyclone separator 112 through a pipeline, a dust removal fan 114 is installed at the bottom end of the filter cartridge 113, and an air supply pipe 115 is installed at the exhaust port of the dust removal fan 114. The air supply pipe 115 is connected to the dust removal box body 1, and the air supply pipe 115 is directly opposite to the air inlet 1 0, start the dust removal fan 114, and absorb the dust inside the transition box 4 into the cyclone separator 112 through the exhaust pipe 111. The inhaled dust-laden gas can remove larger particles of dust through the cyclone separator 112, and then the gas enters the filter cartridge 113 to filter the tiny particles of dust. Then the dust removal fan 114 transports the filtered clean gas through the air supply pipe 115 to the dust removal box body 1 again, thus completing the circulating dust removal before material loading.

[0048] According to the technical solution of this embodiment, a dust collecting bucket 116 is installed at the bottom of the cyclone separator 112 through a pipeline. The cyclone separator 112 collects larger dust particles in the air and drops them into the dust collecting bucket 116 for centralized processing.

[0049] According to the technical solution of this embodiment, a filter element 117 is installed inside the filter cartridge 113. The filter element 117 can be replaced regularly to maintain the filtering effect at all times.

[0050] Specifically, when dust removal is required, the material is first put into the dust removal box 1 through the feed pipe 2, and then falls and is evenly distributed on the material diverter plate 9. At this time, the high-pressure gas blown out by the dust removal fan 114 through the air supply pipe 115 enters the interior of the material diverter plate 9 through the air inlet hole 10. Ventilation holes are provided on the side walls of the material diverter plate 9. The diameter of the ventilation holes is smaller than the particle size of the material. When the air flow blows into the interior of the material diverter plate 9 from the air inlet hole 10, the air flow will pass through the ventilation holes and blow up the dust in the material from the inside to the outside. At this time, the dust can be sucked into the exhaust pipe 111 by cooperating with the dust collection hood 3, thereby forming the first dust removal. The raw materials after the first dust removal continue to fall to the ventilation partition 5. At this time, the air supply pipe 115 passes through The high-pressure gas blown out from the air supply transition part 8 blows up the dust that has not been removed cleanly in the raw material again through the ventilation holes of the ventilation baffle 5, and the dust can be sucked into the exhaust pipe 111 in conjunction with the dust hood 3 again, thereby completing the second dust removal. The dust-laden gas sucked into the exhaust pipe 111 will pass through the cyclone separator 112 to remove larger particles of dust, and then the gas enters the filter cartridge 113 to filter the tiny particles of dust. The dust removal fan 114 then transports the filtered clean gas through the air supply pipe 115 to the dust removal box 1 again, thereby completing the circulating dust removal before the material is loaded. It should be noted that the dust removal effect can be guaranteed by regularly cleaning the dust in the dust collecting bucket 116 and cleaning and replacing the filter element 117.
