Description

Technical Field

[0001] The utility model relates to the technical field of chemical feeding equipment, in particular to a chemical raw material feeding device. Background Art

[0002] Chemical raw materials are raw materials used in the chemical industry. In the processing of chemical raw materials, a feeding device is required to transport the chemical raw materials. For example, a chemical raw material feeding device disclosed in Chinese patent application number CN202320674955.X includes a material box, a stirring device, a scraping device, a chassis, a feeding tray, a feeding port and a driving mechanism. The stirring device is arranged on the material box, the scraping device is arranged on the stirring device and is located on the inner wall of the material box, the chassis is arranged at the lower part of the material box, the feeding tray is rotatably arranged in the chassis and is attached to the lower outlet of the material box, the feeding port is arranged on the chassis, and the driving mechanism is arranged at the lower part of the chassis. The second motor is started, the rotating disk rotates, the sleeve second rotates, the connecting rod second rotates, and when the lever rotates into the chute, it slides in the chute, and at the same time, the chute is toggled, driving the toggle plate to rotate a certain angle until the lever comes out from the other end of the chute. The toggle plate drives the feeding plate to rotate a certain angle until the batching trough is aligned with the discharge port, and the raw materials in the batching trough are transported out along the discharge port. The following technical problems exist:

[0003] Affected by the amount of chemical raw materials inside the material box, the pressure at the discharge port is different. When there are more chemical raw materials inside the material box, the pressure at the discharge port is higher, which makes the gaps between the chemical raw materials smaller. As a result, there are more chemical raw materials in the batching trough. When there are fewer chemical raw materials inside the material box, the pressure at the discharge port is lower, which makes the gaps between the chemical raw materials larger. As a result, there are fewer chemical raw materials in the batching trough, and ultimately it is difficult to control the output of chemical raw materials. Utility Model Content

[0034] The feed box 001 includes a box body 100. A stirring cavity 110 is formed inside the box body 100. A plurality of guiding blocks 111 for controlling the pressing of the stirring device 002 are fixedly installed at the lower end of the cavity of the stirring cavity 110. A feeding port 120 for facilitating the feeding of materials into the cavity of the stirring cavity 110 is installed at the upper end of the box body 100. A fixing frame 130 for cooperating with the limiting device 003 to support the box body 100 is fixedly installed on the outer wall of the middle part of the box body 100, and the fixing frame 130 is located at the upper end of the support platform 410. A blanking pipe 140 for conveying chemical raw materials to the feeding column 420 is fixedly installed at the lower end of the box body 100.

[0035] A stirring device 002 for stirring chemical raw materials is installed inside the feed box 001. The stirring device 002 includes a transmission rod 200, and a scraping component 300 is installed at the lower end of the transmission rod 200. A plurality of stirring rods one 210 for stirring chemical raw materials are fixedly installed on the side of the transmission rod 200. A motor 220 for controlling the rotation of the transmission rod 200 is fixedly installed at the upper end of the transmission rod 200. By starting the motor 220, the transmission rod 200 drives the stirring rods one 210 and the scraping component 300 to stir the chemical raw materials synchronously.

[0036] The stirring device 002 includes a scraping component 300. The scraping component 300 includes a limiting disc 310. A bolt one 311 for facilitating the fixation of the limiting disc 310 with the transmission rod 200 is installed in the middle of the limiting disc 310. A threaded hole is formed at the bottom of the transmission rod 200. By rotating the pair of bolts one 311, the scraping component 300 is fixed firmly at the bottom of the transmission rod 200. A plurality of stirring rods two 312 for cooperating with the stirring rods one 210 to stir chemical raw materials are fixedly installed on the outer wall of the limiting disc 310, and a pressing component 320 is installed at the bottom end of the stirring rods two 312.

[0037] A pressing component 320 for cooperating with the guiding block 111 to press the material is installed at the lower end of the scraping component 300. The pressing component 320 includes a fixing plate 321. A second bolt 322 for cooperating with the second stirring rod 312 to limit the pressing component 320 is installed in the middle of the fixing plate 321. A threaded hole is opened at the bottom of the second stirring rod 312. By rotating the second bolt 322, the fixing plate 321 is fixed to the bottom end of the second stirring rod 312. An arc-shaped inclined plate 323 for cooperating with the guiding block 111 to press down the chemical raw materials is fixedly installed on one side of the fixing plate 321, and the arc-shaped inclined plate 323 is an elastic block. The guiding block 111 is located at the upper end of the arc-shaped inclined plate 323. A sliding-out groove 324 for the guiding block 111 to slide out is opened at one end of the arc-shaped inclined plate 323 close to the fixing plate 321.

[0038] When the second stirring rod 312 rotates, it drives the pressing component 320 to rotate at the bottom of the cavity of the stirring cavity 110. When the pressing component 320 drives the arc-shaped inclined plate 323 to rotate, the upper surface of the lower end of the arc-shaped inclined plate 323 abuts against the guiding block 111. When the pressing component 320 rotates, the guiding block 111 slides from the lower end of the arc-shaped inclined plate 323 to the upper end of the arc-shaped inclined plate 323, thereby driving the arc-shaped inclined plate 323 to deform. The lower end of the arc-shaped inclined plate 323 moves downward to press the chemical raw materials, reducing the gap between the chemical raw materials and reducing the error of each feeding. The pressing component 320 continues to rotate, driving the guiding block 111 to slide out from the notch of the sliding-out groove 324, and the guiding block 111 continues to press the next arc-shaped inclined plate 323, and so on.

[0039] A limiting device 003 for supporting the material box 001 is installed at the lower end of the material box 001. The limiting device 003 includes a limiting bottom plate 400. A supporting platform 410 for supporting the box body 100 is fixedly installed at the upper end of the limiting bottom plate 400. A limiting hole 411 for limiting the box body 100 is opened in the middle of the supporting platform 410.

[0040] A feeding column 420 for feeding is movably installed at the lower end of the limiting bottom plate 400. Stacking holes 421 for temporarily storing chemical raw materials are opened at both ends of the feeding column 420. An electric push rod 430 for pushing the feeding column 420 is fixedly installed at one end of the feeding column 420. A limiting plate 440 for limiting the electric push rod 430 is fixedly installed at one end of the electric push rod 430. A baffle plate 450 for closing the stacking holes 421 is fixedly installed in the middle of the bottom end of the limiting bottom plate 400, and the feeding column 420 moves left and right in the middle of the baffle plate 450. The baffle plate 450 is a U-shaped plate body.

[0041] When the electric push rod 430 pushes the feeding column 420, it drives the stacking hole 421 at the left end to move to the middle of the baffle 450, and the stacking hole 421 at the right end moves away from the baffle 450. When the electric push rod 430 pulls the feeding column 420, it drives the stacking hole 421 at the right end to move towards the baffle 450, so that the baffle 450 seals the cavity of the stacking hole 421 at the right end, and the stacking hole 421 at the left end moves away from the baffle 450, and the chemical raw materials in the stacking hole 421 at the left end fall due to gravity. Two limiting blocks 460 for limiting the feeding column 420 are fixedly installed at the lower end of the limiting bottom plate 400. The limiting blocks 460 are located on the left and right sides of the baffle 450, so that when the electric push rod 430 drives the feeding column 420 to move back and forth, it is convenient for the stacking hole 421 to be aligned with the middle hole cavity of the limiting bottom plate 400.

[0042] A material discharging port is formed in the middle of the limiting bottom plate 400, which is convenient for the chemical raw materials to fall into the cavity of the stacking hole 421 through the material discharging pipe 140 and the material discharging port. By pushing the feeding column 420 with the electric push rod 430, the stacking hole 421 is aligned with the material discharging port in the middle of the limiting bottom plate 400, which is convenient for the chemical raw materials to fall into the cavity of the stacking hole 421.

[0043] Based on the above content and drawings, those skilled in the art can understand and implement the present utility model. In addition, any non-creative modifications made to the present utility model by those skilled in the art without creative efforts still fall within the protection scope of the present utility model.
