Description

Technical Field

[0002] Potassium nitrate is a colorless, transparent orthorhombic crystal or white granular powder, which is odorless and non-toxic. It is easily soluble in water but hardly soluble in ethanol. In the agricultural field, potassium nitrate is a high-quality compound fertilizer that can provide nitrogen and potassium elements to plants and enhance their resistance to stress. In industry, it is an important raw material for the manufacture of gunpowder, glass and other products. It has good water solubility but is hardly soluble in ethanol. When removing impurities from it, such as cleaning sodium chloride from the surface of potassium nitrate crystals, it needs to be rinsed with ethanol; When using ethanol for flushing, the material needs to be fully in contact with ethanol, but traditional supporting devices make it difficult to flip the material, which can easily result in poor potassium nitrate impurity removal effect. In addition, ethanol is highly volatile. If flushing is not performed in a closed environment, ethanol gas will evaporate, which can easily lead to danger.

The shunt pipe 19 is arranged below the transfer frame 16. The closing cover 14 provides stable support for the transfer frame 16 and the shunt pipe 19, and also provides stable support for the carrying box 2 in the filtering state. When loading, the second motor 15 is started, and the second motor 15 drives the auger 18 to rotate. The material in the storage box is gradually sent into the filter box 3 as the auger 18 rotates. After the loading is completed, the second motor 15 stops rotating and starts the liquid supply pump 21. The liquid supply pump 21 sends the cleaning liquid in the liquid supply box 20 into the connecting pipe 22, and the cleaning liquid is finally discharged from the output head of the shunt pipe 19 to flush the material in the filter box 3.

[0021] During actual use, it is also necessary to collect the cleaning liquid after cleaning in time and to process the gas in the bearing chamber. To this end, a drain pipe 23 and an exhaust pipe 24 are symmetrically arranged on both sides of the end of the bearing chamber away from the opening.

The top plate 28 is provided above the feeding assembly, and the second legs 27 connected to the workbench 1 are provided at the four corners below the top plate 28. The liquid collecting assembly includes a liquid collecting pipe 29, a lifter 30, a first lifting plate 31, a liquid collecting pump 32 and a liquid collecting box 33. The upper and lower ends of the lifter 30 are respectively connected to the first lifting plate 31 and the bottom plate 26. The liquid collecting box 33 is also provided on the bottom plate 26. One end of the liquid collecting pump 32 is connected to the liquid collecting box 33, and the other end of the liquid collecting pump 32 is connected to the output end of the liquid collecting pipe 29. The input end of the liquid collecting pipe 29 passes through the first lifting plate 31 and is plugged into the drain pipe 23. The exhaust assembly includes an exhaust fan 34, an exhaust gas treatment box 35, a gas collecting pipe 36, a second lifting plate 37, a first lifting plate 38, a second lifting plate 39, a second lifting plate 40, a second lifting plate 41, a second lifting plate 42, a second lifting plate 43, a second lifting plate 44, a second lifting plate 45, a second lifting plate 46, a second lifting plate 47, a second lifting plate 48, a second lifting plate 4 ... The lowering plate 37, the second gear 38, the second rack 39 and the third rack 40, the exhaust fan 34 and the exhaust gas treatment box 35 are both arranged on the top plate 28, the output end of the exhaust fan 34 is connected to the exhaust gas treatment box 35, the input end of the exhaust fan 34 is connected to the output end of the collecting pipe 36, the input end of the collecting pipe 36 passes through the second lifting plate 37 and the top plate 28 and is plugged into the exhaust pipe 24, the second leg 27 is also rotatably provided with a second gear 38, the upper and lower sides of the first lifting plate 31 are provided with a second rack 39 meshing with one side of the second gear 38, the lower sides of the second lifting plate 37 are provided with a third rack 40 meshing with the other side of the second gear 38, initially when the slide plate 11 is in the initial state The drain pipe 23 and the exhaust pipe 24 are both in a horizontal state, the lifter 30 adopts a cylinder, and the lifter 30 is in a retracted state. At this time, the second rack 39 is meshed with one side of the second gear 38, and the third rack 40 is meshed with the other side of the second gear 38. The second rack 39 and the third rack 40 are both in a vertical parallel state. At this time, the distance between the first lifting plate 31 and the second lifting plate 37 is large, and the top wall of the liquid collecting pipe 29 is below the slide plate 11. Therefore, during the movement of the slide plate 11, the liquid collecting pipe 29 will not cause motion interference to the slide plate 11. After the carrying box 2 becomes horizontal, the exhaust pipe 24 and the drain pipe 23 are in a vertical state. At this time, the air collecting pipe 36 is located above the exhaust pipe 24, and the equipment will not cause motion interference. Before the flushing operation,The lifter 30 drives the second lifting plate 37 to rise. The part of the liquid collecting pipe 29 passing through the second lifting plate 37 adopts a rigid structure, and the part connected to the liquid collecting pump 32 is a flexible structure. A sealing ring in interference fit with the drain pipe 23 can be arranged on the inner wall of the liquid collecting pipe 29. The liquid collecting pipe 29 is stably inserted into the drain pipe 23. As the second lifting plate 37 drives the second rack 39 to rise, the second gear 38 drives the third rack 40 to move downward, and the third lifting plate drives the input end of the gas collecting pipe 36 to descend. The gas collecting pipe 36 is similar in structure to the drain pipe 23 and can be stably and hermetically connected to the exhaust pipe 24. Then, the material is rinsed.

The air supply assembly includes an air supply pump 55, an air supply tank 56 and an air supply pipe 57. The air supply tank 56 is fixed on the workbench 1. One end of the air supply pump 55 is connected to the air supply tank 56, and the other end of the air supply pump 55 is connected to the input end of the air supply pipe 57. The output end of the air supply pipe 57 passes through the closing cover 14. By starting the air supply pump 55, the air supply pump 55 can send the gas in the air supply tank 56 into the bearing cavity to balance the air pressure in the bearing cavity. For the gas that may be generated during the rinsing process, the exhaust fan 34 can be started to send the gas into the waste gas treatment tank 35 for treatment. Inert gas can be filled in the air supply tank 56 to ensure that no reaction occurs with the material in the filter tank 3.,

[0022] During actual use, the feeding assembly includes a closed cover 41, a third motor 42, a worm gear 43, a worm 44 and a screw rod 45.

[0023] In actual use, if the filter box 3 is supported on one side, the filter box 3 may be unstable in rotation. For this reason, an auxiliary part for supporting the filter box 3 is provided near the opening end of the bearing cavity, and the auxiliary part includes a bearing 46 and a support ring 47. The outer ring of the bearing 46 is connected to the bearing cavity, and the inner ring of the bearing 46 is connected to the support ring 47.

The inclined surfaces of the block 52 are arranged in two groups, and one group of inclined surfaces of the block 52 facilitates the stable insertion of the plug 50 into the slot. When the movable slot is aligned with the insertion hole, the elastic member 51 pushes the block 52 into the insertion hole. It should be noted that since the inclined surfaces of the block 52 are arranged in two groups, when the filter box 3 carrying the cleaned material is in a vertical state, when the filter box 3 is driven upward by the handle 48 to move, the other group of inclined surfaces of the block 52 presses against the hole, and the elastic member 51 contracts until the block 52 is received in the movable slot, so that the plug 50 is convenient to detach from the connection frame 4. When the filter frame rotates, the support ring 47 connected to the bearing 46 cooperates with the connecting member to stably support the filter box 3, so that the material it carries can move stably, and the arc ring 49 prevents the material from detaching from the opening of the filter box 3 in the horizontal state, while not affecting the subsequent transfer of the material and the cleaning of the inner wall of the filter box 3.

[0024] During actual use, the filter box 3 is further provided with a plurality of groups of friction blocks 53 near one end of the connecting piece. The friction blocks 53 are arranged around the connecting piece. The filter box 3 is in a vertical state, and the bottom wall of the friction block 53 is lower than the plug block 50. The plug block 50 does not contact the inner wall of the bearing cavity, which facilitates the transfer and storage of the filter box 3 carrying materials.

[0025] During actual use, an auxiliary cover 54 is also provided on the second leg 27 to cover the second rack 39, the second gear 38 and the third rack 40. The auxiliary cover 54 is penetrated from top to bottom to ensure the stability of the second rack 39, the second gear 38 and the third rack 40.
