[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a dust-free feeding device for chemical applications, comprising: a support platform 1, a feeding box 2 installed on the top of the support platform 1, a feeding port on one side of the feeding box 2, and a discharge port at the bottom of the feeding box 2; a fan 5 fixedly connected to the top of the feeding box 2, the input end of the fan 5 placed inside the feeding box 2 and equipped with a filter section, a gas storage cylinder 15 for cleaning the filter section installed on the outside of the feeding box 2, and a pulse gas valve installed at one end of the gas storage cylinder 15; an anti-bridging component placed inside the feeding box 2, the anti-bridging component including a scraper 12 slidably connected to the inner wall of the feeding box 2, a reciprocating screw 10 for driving its reciprocating motion installed in the middle of the scraper 12, and a fan wheel 13 linked to the fan 5 fixedly connected to one end of the reciprocating screw 10.

[0022] It should be noted that this embodiment includes a controller and a corresponding control panel. When the blower 5 is turned on, material is poured in through the feeding port and falls into the lower device through the discharge port. During this process, the blower 5 drives the impeller 13 to rotate via wind pressure. The impact force of the wind pressure driving the impeller 13 is greater than the load between the reciprocating screw 10 and the scraper 12, thus causing the impeller 13 to drive the reciprocating screw 10 to rotate. The reciprocating screw 10 drives the scraper 12 to reciprocate, scraping and cleaning the inner wall of the feeding box 2 to prevent it from sticking to the inner wall. The flying particles enter the filter element 7 under the negative pressure of the blower 5 and are filtered and collected. After feeding is complete, the filter section can be cleaned in reverse using the high-pressure air inside the air storage bottle 15.

[0023] In one embodiment, a cover plate 4 is rotatably connected to the feeding port on one side of the feeding box 2, and a limiting pin 16 for limiting the cover plate 4 is slidably connected to one side of the feeding box 2. A spring 17 is sleeved on the outside of the limiting pin 16.

[0024] It should be noted that, in this embodiment, when feeding, the limiting pin 16 is pulled to one side, and the cover plate 4 is flipped upward to open. At this time, the spring 17 is compressed. When the cover plate 4 is flipped to the designated position, the limiting pin 16 is released, and the spring 17 drives the limiting pin 16 to reset, so that the limiting pin 16 blocks the bottom of the cover plate 4, thereby limiting and blocking the cover plate 4. When the cover plate 4 is covering the feeding port, the outer side of the cover plate 4 can be locked and limited by the limiting pin 16.

[0025] In one embodiment, the filtration unit includes a filter cylinder 6 fixed to the air inlet of the fan 5, a filter element 7 installed inside the filter cylinder 6, and a dust suction cover 8 with an air inlet installed at the bottom of the filter cylinder 6. The exhaust end of the gas storage bottle 15 enters the interior of the filter element 7 through the dust suction cover 8 via a pipe.

[0026] It should be noted that in this embodiment, an air blowing pipe is fixedly connected to the middle of the dust suction cover 8, and multiple air outlets are equidistantly opened on the outer side of the air blowing pipe. The air pipe at one end of the air storage bottle 15 is connected to the air blowing pipe. Under the action of the fan 5, the inside of the filter cylinder 6 is in a negative pressure state. Air and dust enter the filter cylinder 6 through the holes of the dust suction cover 8, are filtered by the filter element 7, and are discharged from one end of the fan 5. When cleaning is required, the cover plate 4 is placed on the feeding port, and the high pressure air inside the air storage bottle 15 impacts the filter element 7 inside the filter cylinder 6 from the inside to the outside to clean it, so that the blown dust falls into the feeding box 2 through the dust suction cover 8.

[0027] In one embodiment, a filter screen 3 is installed inside the feeding box 2.

[0028] It should be noted that in this embodiment, it is used to support the material bag and prevent foreign objects from entering the feeding box 2.

[0029] In one embodiment, a slide rod 9 is fixedly connected inside the feeding box 2, and a scraper 12 is slidably connected to the slide rod 9. Rubber sleeves 11 are fixedly connected to both sides of the scraper 12. The rubber sleeves 11 are fitted on the outside of the reciprocating screw 10, and one end of the rubber sleeve 11 is fixedly connected to the inner wall of the feeding box 2. A wind box 14 is fixedly connected to the outside of the feeding box 2. The output end of the blower 5 is connected to the wind box 14 through an air supply pipe 18. The impeller 13 is rotatably installed inside the wind box 14.

[0030] It should be noted that in this embodiment, the blower 5 sends high-pressure air into the air box 14 through the air supply pipe 18. The high-pressure air blows air from one side of the air box 14 onto the impeller 13, and then the air is discharged from one side of the impeller 13. During the rotation of the impeller 13, the impeller 13 drives the reciprocating screw 10 to rotate. The reciprocating screw 10 drives the scraper 12 to move outside the slide rod 9, so that the scraper 12 scrapes the inner wall of the feeding box 2. During the movement of the scraper 12, the rubber sleeves 11 on both sides are stretched and compressed respectively, so as to prevent the material from falling outside the reciprocating screw 10 and affecting the conveying of the reciprocating screw 10.
