Description

A device that can improve the sieving of sodium sulfate Technical Field

[0001] This utility model relates to the field of sodium sulfate sieving technology, and in particular to a device that can improve sodium sulfate sieving efficiency. Background Technology

[0002] Glauber's salt is a commonly used traditional Chinese medicine. Its main component is anhydrous sodium sulfate (Na2SO4). It is produced by boiling Glauber's salt (Na2SO4·10H2O) with other medicines, crystallizing it, and then dehydrating and weathering it. Due to differences in origin and refining methods, the impurities it contains also vary. It has the effects of purging heat and relieving constipation; softening and dispersing nodules; clearing heat and detoxifying; clearing the lungs and relieving summer heat; eliminating food stagnation and harmonizing the stomach.

[0003] Existing sodium sulfate sieving devices generate a large amount of sodium sulfate dust, especially at the feed point, when sodium sulfate is added to the sieving device for sieving. This dust is directly suspended in the air and cannot be recycled, resulting in waste of sodium sulfate. Moreover, if the screen is fixed during the sieving process, the sieving speed is slow, resulting in poor sieving efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a device for improving the sieving of sodium sulfate, so as to solve the problems mentioned in the background art.

[0005] An apparatus for improving the sieving of sodium sulfate, comprising:

[0006] Screening tank;

[0007] A feed hopper is connected to the upper end of the screening tank;

[0008] A dust recovery assembly, wherein the dust recovery assembly is located outside the feed hopper;

[0009] The screening box has an opening facing downward and is located inside the screening tank. A feeding hose connects the feeding hopper and the screening box, and screening mesh plates cover both sides of the lower end of the screening box.

[0010] A screening drive assembly is located outside the screening recess.

[0011] Preferably, the feed hopper is fitted with a feed protection cover fixed to the upper end of the screening tank, and the upper end of the feed protection cover is covered with a cover plate.

[0012] Preferably, the dust recovery assembly includes a suction pump, a return hose, an annular pipe, and several suction hoods. The suction pump is fixed to the upper end of the screening tank. The return hose connects the discharge port of the suction pump to the upper end of the screening box. The annular pipe is fixedly sleeved around the feed hopper. All suction hoods are connected to the upper end of the annular pipe, and the suction ports of the suction hoods all face upwards from the feed hopper inlet.

[0013] Preferably, the screening drive assembly includes a motor, a rotating rod, impact balls, a semi-circular impact block, and a spring telescopic rod. The motor is fixed to the inner wall of the screening tank. The rotating rod is connected to the power end of the motor. There are two impact balls, which are respectively fixed to both ends of the rotating rod. The semi-circular impact block is fixed to the outer wall of the screening box. The impact balls and the semi-circular impact blocks correspond to each other. One end of each spring telescopic rod is connected to both sides of the screening box, and the other end of the spring telescopic rod is connected to the inner wall of the screening tank.

[0014] Preferably, gears are rotatably connected to the lower ends of both sides of the screening box, one side of the screening screen plate is fixed to the adjacent gear, a toothed plate is meshed on the outside of each gear, a lifting plate is fixed to the upper end of each toothed plate, an electric cylinder is fixed to both sides of the screening box, and the upper end of each lifting plate is connected to the power end of the adjacent electric cylinder.

[0015] Preferably, the lower end of the screening tank is connected to a discharge valve.

[0016] The beneficial effects of this utility model are as follows: When sodium sulfate is added to the screening box through the feed hopper, the suction pump starts working, and then the dust generated is absorbed by multiple suction hoods. The absorbed dust is discharged into the screening box for further screening, which effectively prevents the dust from being directly blown into the air and facilitates the timely recycling of sodium sulfate dust, effectively reducing the waste of sodium sulfate. Furthermore, the operation of the screening drive component facilitates the left and right swinging of the screening box and the screening screen, thus facilitating the swinging screening of sodium sulfate by the screening screen, effectively improving the screening efficiency of sodium sulfate.

[0023] Please refer to Figures 1-5. An apparatus for improving the sieving of sodium sulfate includes:

[0024] A screening tank 1; a feed hopper 3 connected to the upper end of the screening tank 1; a dust recovery assembly located outside the feed hopper 3; a screening concave box 6 with its opening facing downwards and located inside the screening tank 1; a feed hose 5 connecting the feed hopper 3 and the screening concave box 6; screening mesh plates 7 covering both sides of the lower end of the screening concave box 6; and a feed protective cover 2 fixed to the upper end of the screening tank 1, the feed protective cover 2... The upper end is covered with a cover plate 4. The dust recovery assembly includes a suction pump 9, a return hose 21, an annular pipe 10, and several suction hoods 11. The suction pump 9 is fixed to the upper end of the screening tank 1. The return hose 21 is connected between the discharge port of the suction pump 9 and the upper end of the screening box 6. The annular pipe 10 is fixedly sleeved around the feed hopper 3. The suction hoods 11 are all connected to the upper end of the annular pipe 10, and the suction ports of the suction hoods 11 are all facing upwards from the feed port of the feed hopper 3.

[0025] When screening sodium sulfate using this device, the cover plate 4 is opened and sodium sulfate is added into the feed hopper 3. The sodium sulfate is discharged into the screening box 6 through the feed hose 5, and then screened through the screening screen plate 7. During this process, the suction pump 9 is started at the same time, and the dust generated at the feed hopper 3 is absorbed through multiple suction hoods 11. The absorbed dust is discharged into the screening box 6 through the annular pipe 10 and the return hose 21, and then screened again through the screening screen plate 7. Because the dust at the feed hopper 3 is absorbed in time, and the cover plate 4 is placed on the upper end of the feed protection cover 2 after feeding is completed, the dust is effectively prevented from drifting directly into the air, and it is also conducive to timely recycling of the sodium sulfate dust, effectively reducing the waste of sodium sulfate.

[0026] A screening drive assembly is located outside the screening chamber 6. The screening drive assembly includes a motor 12, a rotating rod 13, impact balls 14, semi-circular impact blocks 15, and a spring telescopic rod 8. The motor 12 is fixed to the inner wall of the screening tank 1. The rotating rod 13 is connected to the power end of the motor 12. Two impact balls 14 are provided and fixed to both ends of the rotating rod 13 respectively. The semi-circular impact blocks 15 are fixed to the outer wall of the screening chamber 6. The impact balls 14 and the semi-circular impact blocks 15 correspond to each other. One end of the spring telescopic rod 8 is connected to both sides of the screening chamber 6, and the other end of the spring telescopic rod 8 is connected to the inner wall of the screening tank 1.

[0027] When the screening screen 7 screens the sodium sulfate, the starting motor 12 drives the rotating rod 13 and the impact ball 14 to rotate. The impact ball 14 continuously impacts the semi-circular impact block 15 through the arc surface, thereby continuously pushing the screening box 6 to the left. During this process, the screening box 6 will compress or stretch the corresponding spring telescopic rod 8. Therefore, combined with the elasticity of the spring telescopic rod 8, the screening box 6 moves back and forth left and right, which facilitates the oscillation of the screening box 6 and the screening screen 7. This facilitates the oscillating screening of sodium sulfate by the screening screen 7, effectively improving the screening efficiency of sodium sulfate.

[0028] The lower end of the screening tank 1 is connected to a discharge valve 16.

[0029] When the qualified sodium sulfate accumulated at the bottom of the screening tank 1 needs to be discharged, the qualified sodium sulfate at the bottom of the screening tank 1 can be discharged by opening the discharge valve 16.

[0030] Gears 20 are rotatably connected to the lower ends of both sides of the screening box 6. One side of the screening screen plate 7 is fixed to the adjacent gear 20. A toothed plate 19 meshes with the gear 20. A lifting plate 18 is fixed to the upper end of the toothed plate 19. An electric cylinder 17 is fixed to both sides of the screening box 6. The upper end of the lifting plate 18 is connected to the power end of the adjacent electric cylinder 17.

[0031] When it is necessary to discharge the unqualified sodium sulfate on the screening screen plate 7, after the sodium sulfate at the bottom of the screening tank 1 has been discharged, the lifting plate 18 and the toothed plate 19 are moved upward by the retraction of the electric cylinder 17. The toothed plate 19 will drive the gear 20 to rotate. At this time, the gear 20 will drive the screening screen plate 7 to rotate and unfold, so that the screening screen plate 7 is tilted. Then, the unqualified sodium sulfate remaining on the screening screen plate 7 will slide into the bottom of the screening tank 1 along the screening screen plate 7. Therefore, by opening the discharge valve 16, it is convenient to discharge the unqualified sodium sulfate at the bottom of the screening tank 1.

[0032] Working principle: By opening the cover plate 4, sodium sulfate is added into the feed hopper 3. The sodium sulfate is discharged into the screening box 6 through the feed hose 5, and then screened by the screening screen plate 7. During this process, the suction pump 9 is started at the same time, and the dust generated at the feed hopper 3 is absorbed by multiple suction hoods 11. The absorbed dust is discharged into the screening box 6 through the annular pipe 10 and the return hose 21, and then screened by the screening screen plate 7. At the same time, the motor 12 is started to drive the rotating rod 13 and the impact ball 14 to rotate. The impact ball 14 continuously impacts the semi-circular impact block 15 through the arc surface, thereby continuously pushing the screening box 6 to the left. During this process, the screening box 6 will compress or stretch the corresponding spring telescopic rod 8. Therefore, combined with the elasticity of the spring telescopic rod 8, the screening box 6 moves back and forth left and right, which facilitates the oscillation of the screening box 6 and the screening screen plate 7. Thus, it is beneficial to drive the screening screen plate 7 to oscillate and screen the sodium sulfate.
