[0001] The utility model belongs to the technical field of chemical raw material processing, in particular to a chemical raw material unloading device with an anti-blocking structure. Background Art

[0002] There are many types of chemical raw materials with a wide range of uses. Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. Most of these chemical raw materials are processed in reactors. Since liquid chemical raw materials have good fluidity, they are not prone to blockage during feeding and discharging. However, some solid and powdered chemical raw materials are prone to accumulation and adhesion in reactors or storage barrels, thereby blocking the discharge pipe and causing uneven discharge. Utility Model Content

[0003] In order to overcome the above defects, the utility model provides a chemical raw material feeding device with an anti-blocking structure, which solves the problem that some solid and powdered chemical raw materials are easily accumulated in the reaction kettle or storage barrel, have poor fluidity, and are easily blocked by the discharge pipe during feeding.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemical raw material unloading device with an anti-blocking structure, comprising a unloading barrel, a support frame is installed on the unloading barrel, a discharge pipe is connected to the bottom of the unloading barrel, an end cover is installed on the top of the unloading barrel, a filling port is connected to one side above the end cover, a first mounting plate is connected to the end cover, a first motor is installed on the first mounting plate, a rotating rod is connected to the output shaft of the first motor, a connecting plate is connected to one end of the rotating rod, a connecting block is connected to the rotating rod, and a stirring rod is connected to the connecting block;

[0005] The discharge pipe is connected to a fixed box, a sliding groove is opened on the inner wall of the fixed box, a telescopic rod is connected inside the fixed box, a second mounting plate is connected to the fixed box, a second motor is mounted on the second mounting plate, a rotating shaft is connected to the output shaft of the second motor, one end of the rotating shaft is connected to a half-tooth gear, the half-tooth gear is meshingly connected to a rack, one end of the rack is connected to a fixed plate, and a knocking block is connected to the fixed plate.

[0006] As a further solution of the utility model: the four stirring rods are symmetrical about the axis of the rotating rod and are obliquely connected to the connecting block, and scrapers are obliquely connected to both sides of the connecting plate.

[0007] As a further solution of the utility model: the bottom of the discharge barrel is of conical design, and the scraper is in close contact with the inner wall of the conical bottom of the discharge barrel.

[0008] As a further solution of the utility model: a sliding plate is connected to the rack, the rack is slidably connected to the sliding groove through the sliding plate, and the rack and the fixed plate form an L shape as a whole.

[0009] As a further solution of the utility model: one end of the telescopic rod is connected to the rack, a spring is sleeved on the telescopic rod, one end of the spring is connected to the fixing box, and the other end of the spring is connected to the rack.

[0010] As a further solution of the utility model: a base is connected below the support frame, an anti-skid pad is connected below the base, and anti-skid patterns are arranged below the anti-skid pad.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The chemical raw material unloading device with an anti-blocking structure is provided with a half-toothed gear, a rack, a sliding plate, a slide groove, a telescopic rod, a spring, a fixed plate and a knocking block. By starting a second motor to drive the half-toothed gear to rotate, the meshing of the half-toothed gear and the rack will push the rack to drive the fixed plate to move, so that the sliding plate slides in the slide groove, and the movement of the rack will stretch the telescopic rod and the spring. As the half-toothed gear continues to rotate, the rack will eventually disengage from the meshing with the half-toothed gear. At this time, the spring rebounds and pulls the rack to move, so that the knocking block can hit the discharge pipe, thereby loosening the chemical raw materials blocked in the discharge pipe, prompting the chemical raw materials to flow out of the discharge pipe smoothly, and avoiding uneven discharge caused by blockage of the discharge pipe.

[0013] 2. The chemical raw material unloading device with an anti-blocking structure is provided with a first motor, a rotating rod, a stirring rod, a connecting plate and a scraper. By starting the first motor to rotate the rotating rod, the rotating rod can drive the stirring rod to stir the chemical raw materials in the unloading barrel, thereby ensuring the flow of the chemical raw materials in the unloading barrel and avoiding the accumulation of chemical raw materials in the unloading barrel to affect the unloading. When the rotating rod rotates, the scraper is driven to rotate through the connecting plate connected at one end, thereby scraping off the chemical raw materials stuck to the inner wall of the bottom of the unloading barrel to avoid chemical raw materials residue. The connecting plate will flip the chemical raw materials above the discharge pipe, thereby avoiding the accumulation of chemical raw materials and ensuring the normal unloading of the discharge pipe.

[0021] A discharge pipe 3 is connected to the bottom of the lower material barrel 1, an end cover 4 is installed above the lower material barrel 1, a filling port 5 is connected to one side above the end cover 4, a first mounting plate 6 is connected to the end cover 4, a first motor 7 is installed on the first mounting plate 6, a rotating rod 8 is connected to the output shaft of the first motor 7, one end of the rotating rod 8 is connected to a connecting plate 9, a connecting block 10 is connected to the rotating rod 8, a stirring rod 11 is connected to the connecting block 10, a total of four stirring rods 11 are symmetrically connected to the connecting block 10 with respect to the axis of the rotating rod 8, and scrapers 12 are obliquely connected on both sides of the connecting plate 9. The chemical raw materials in the lower material barrel 1 are stirred by multiple stirring rods 11 to promote the flow of chemical raw materials and prevent the chemical raw materials from piling up and adhering to each other.

[0022] The bottom of the discharge barrel 1 is of conical design, and the scraper 12 is in close contact with the inner wall of the conical bottom of the discharge barrel 1. The chemical raw materials flow along the conical bottom of the discharge barrel 1 to the discharge pipe 3, and the rotation of the rotating rod 8 can drive the scraper 12 to rotate, thereby preventing the chemical raw materials from adhering to the inner wall.

[0023] A fixed box 13 is connected to the discharge pipe 3, a slide groove 14 is provided on the inner wall of the fixed box 13, a telescopic rod 15 is connected inside the fixed box 13, one end of the telescopic rod 15 is connected to the rack 20, a spring 24 is sleeved on the telescopic rod 15, one end of the spring 24 is connected to the fixed box 13, and the other end of the spring 24 is connected to the rack 20. When the rack 20 moves to drive the knocking block 22 away from the discharge pipe 3, the spring 24 and the telescopic rod 15 will be stretched, so that after the half-tooth gear 19 is disengaged from the rack 20, the spring 24 rebounds and quickly pulls the rack 20, so that the knocking block 22 hits the discharge pipe 3, prompting the discharge pipe 3 to vibrate, so that the chemical raw materials blocked in the discharge pipe 3 are loosened, thereby preventing the discharge pipe 3 from being blocked.

[0024] A second mounting plate 16 is connected to the fixed box 13, a second motor 17 is mounted on the second mounting plate 16, a rotating shaft 18 is connected to the output shaft of the second motor 17, one end of the rotating shaft 18 is connected to a half-toothed gear 19, the half-toothed gear 19 is meshingly connected to a rack 20, one end of the rack 20 is connected to a fixed plate 21, a knocking block 22 is connected to the fixed plate 21, a sliding plate 23 is connected to the rack 20, the rack 20 is slidably connected to the slide groove 14 through the sliding plate 23, the rack 20 and the fixed plate 21 form an L shape as a whole, when the rack 20 moves, the sliding plate 23 will slide in the slide groove 14, thereby guiding the movement of the rack 20 to prevent the rack 20 from being skewed when moving.

[0025] The working principle of the utility model is:

[0026] The staff fills the chemical raw materials from the filling port 5, starts the first motor 7 to rotate the rotating rod 8, so that the rotating rod 8 drives the stirring rod 11 to stir the chemical raw materials in the discharge barrel 1, ensures the flow of the chemical raw materials in the discharge barrel 1, and prevents the chemical raw materials from pushing. When the rotating rod 8 rotates, it drives the scraper 12 to rotate through the connecting plate 9 connected at one end, thereby scraping off the chemical raw materials attached to the bottom inner wall of the discharge barrel 1 to avoid chemical raw materials residue. When the discharge pipe 3 is blocked by the chemical raw materials, the second motor 17 is started to drive the half-tooth gear 19 to rotate. , and the meshing of the half-toothed gear 19 and the rack 20 will push the rack 20 to move, so that the rack 20 drives the fixed plate 21 and the knocking block 22 away from the discharge pipe 3. At the same time, the rack 20 will stretch the telescopic rod 15 and the spring 24. As the half-toothed gear 19 continues to rotate, the rack 20 will eventually disengage from the meshing with the half-toothed gear 19. At this time, the spring 24 rebounds and pulls the rack 20 to move, so that the knocking block 22 can hit the discharge pipe 3, thereby loosening the chemical raw materials blocked in the discharge pipe 3, and promoting the chemical raw materials to flow out of the discharge pipe 3 smoothly.
