Description

Technical Field

[0001] The invention belongs to the technical field of pneumatic conveying equipment, and in particular relates to an anti-overflow conveying device for zinc oxide production. Background Art

[0002] Zinc hypochlorite is an inorganic compound, usually colorless or white crystals, with strong hygroscopicity. In the processing of zinc hypochlorite, its solution or powder needs to be transported to ensure fluidity, avoid solidification, ensure equipment safety, accurately control product concentration and achieve production efficiency.

[0003] When the existing conveying device is used, zinc hypochlorite is usually transported in the conveying pipeline by pneumatic means. However, there are usually the following technical problems in the conveying process: Since zinc hypochlorite is a highly hygroscopic chemical substance and a compound containing salt components, it will quickly absorb moisture in the air during transportation, causing its surface to become wet or even dissolved. When moisture forms on its surface, the combination of moisture and salt will promote crystallization or form a wet and sticky solid, and eventually form agglomerates. Agglomerated zinc hypochlorite is easy to be blocked in the transportation pipeline during transportation, resulting in reduced transportation efficiency. The blocked zinc hypochlorite will further overflow from the input port, resulting in unnecessary waste during transportation. When zinc hypochlorite is transported, a pneumatic conveying pump is usually used to convey gas into a conveying pipeline, and the power of the airflow is used to push the zinc hypochlorite to be transported in the conveying pipeline. However, due to the complexity of the interaction between the flow of zinc hypochlorite and the airflow, it is difficult for the pneumatic conveying pump to accurately adjust the conveying speed of zinc hypochlorite, which further causes the zinc hypochlorite to be easily conveyed too fast or too slow: when the conveying speed is too fast, a large number of bubbles will be generated in the zinc hypochlorite during the conveying process, affecting the stability during transportation and the quality of the produced zinc hypochlorite product; when the conveying speed is too slow, it will lead to solubility saturation, and then cause precipitation or crystallization. The formation of precipitation will not only affect the concentration of zinc hypochlorite, but also may block the conveying pipeline, causing damage to equipment and poor transportation, thereby reducing the transportation efficiency.

[0004] Therefore, there is an urgent need for a zinc chloride production overflow prevention and conveying device that can prevent zinc chloride from agglomerating during the conveying process and adjust the zinc chloride conveying speed in real time to avoid excessively fast or slow conveying speeds.

[0013] Compared with the existing technology, the advantages of this zinc oxide production overflow prevention and conveying device are: 1. The present invention provides a flow disturbance component. When zinc subchloride is transported, the first motor drives the rotating rod to rotate, driving the spiral flow disturbance blades to rotate. During the process of transporting zinc subchloride, the zinc subchloride is subjected to flow disturbance treatment to avoid agglomeration of the zinc subchloride. At the same time, the gas is discharged to the transport pipeline through the flow disturbance hole. The impact of the airflow on the zinc subchloride improves the flow disturbance effect on the zinc subchloride, further preventing the zinc subchloride from agglomerating and clogging in the transport pipeline, thereby improving the transport efficiency and avoiding overflow of the zinc subchloride due to clogging.

[0014] 2. The present invention is provided with a conveying speed regulating component. During the conveying process, the gas flow rate can be selectively increased or decreased according to the conveying speed of zinc chloride. When the conveying speed of zinc chloride is slow, the shear stress generated during the conveying of zinc chloride is small. The pump air box draws outside air when pumping gas and conveys it to the inside of the conveying pipeline to assist the conveying of zinc chloride and increase its conveying speed, thereby avoiding the blockage of the conveying pipeline caused by the slow conveying speed of zinc chloride. When the conveying speed of zinc chloride is fast, the shear stress generated during the conveying of zinc chloride is large. The pump air box draws air at the air delivery channel when pumping gas and conveys it to the conveying pipeline, thereby reducing the gas flow at the air delivery channel. After the pumped gas circulates through the pump air box, the air delivery pipe, the air delivery cavity and the spoiler hole, the driving force of the zinc chloride on the zinc chloride is weakened. Therefore, the conveying speed of zinc chloride can be reduced, thereby avoiding the generation of a large number of bubbles caused by the fast conveying speed of zinc chloride, thereby improving the quality of the produced zinc chloride product.

[0015] 3. The present invention provides a suction assembly. When the pump air box pumps air, the reciprocating screw rod can be driven to rotate by the second motor, so that the piston block can be reciprocated horizontally in the pump air chamber under the action of the guide wheel, thereby realizing continuous pumping of air. In the process of the annular sliding plate sliding from the left side to the middle, it indicates that the zinc chloride delivery speed increases to a suitable delivery speed under a relatively slow condition. In this process, the closer the zinc chloride delivery speed is to the suitable delivery speed, the smaller the amount of external air sucked, and the lower the effect of assisting the delivery of zinc chloride. In the process of the annular sliding plate sliding from the middle to the right side, it indicates that the zinc chloride increases from a suitable delivery speed to a faster delivery speed. In this process, the greater the zinc chloride delivery speed is under a relatively fast condition, the more air is sucked in the air delivery channel, and the greater the reduction in the zinc chloride delivery speed. In the process of zinc chloride delivery, the specific enhancement amount and reduction amount of the delivery speed can be adjusted in real time, further avoiding the zinc chloride delivery speed being too fast or too slow, so that the delivery speed is always kept within a suitable range, thereby improving the delivery efficiency and the stability of zinc chloride during the delivery process.

[0016] 4. The present invention provides a stabilizing component. During the operation of the spoiler component, the rotation of the rotating rod causes the piston plate in the extraction cylinder to perform reciprocating horizontal displacement under the action of the reciprocating threaded section, thereby continuously pumping the stabilizer in the liquid storage tank into the extraction cylinder, and continuously pumping the stabilizer in the extraction cylinder out into the delivery pipeline, so that the zinc hypochlorite maintains a longer stable period during storage and transportation, thereby avoiding decomposition reaction.

DETAILED DESCRIPTION

[0019] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0020] Example: Refer to Figures 1 to 6 , a zinc oxide production overflow prevention and conveying device, comprising: A gas transmission channel 1, one end of the gas transmission channel 1 is fixedly connected to a delivery pipeline 11, one end of the delivery pipeline 11 away from the gas transmission channel 1 is fixedly connected to a detection channel 12, and one end of the detection channel 12 away from the delivery pipeline 11 is fixedly connected to a discharge pipeline 13; The spoiler assembly 2 is used to prevent the occurrence of agglomeration during the transportation of zinc hypochlorite. The spoiler assembly 2 includes a rotating rod 21 that penetrates and is rotatably connected to the side wall of the gas transmission channel 1. A spiral spoiler blade 22 is provided on the peripheral side wall of the rotating rod 21. A driving component 23 for driving the rotating rod 21 and the spiral spoiler blade 22 to rotate is fixedly connected to the outer wall of the gas transmission channel 1. An air transmission cavity is provided inside the rotating rod 21. A plurality of spoiler holes 24 distributed in a spiral array are provided on a side wall of the spiral spoiler blade 22 away from the gas transmission channel 1. The air transmission cavity is connected to the interior of the delivery pipeline 11 through the plurality of spoiler holes 24. A pump air box 25 is fixedly connected to the upper end of the delivery pipeline 11. An air transmission pipe 26 is fixedly connected between the interior of the pump air box 25 and the air transmission cavity.

[0021] Specifically, the driving component 23 includes a first motor 231 fixedly connected to the outer wall of the gas transmission channel 1, a gear 232 is fixedly connected to the output end of the first motor 231, and the part of the rotating rod 21 extending outside the gas transmission channel 1 is fixedly connected to a gear ring 233 meshing with the gear 232.

[0022] In view of the problem that zinc subchloride in the prior art is easy to form lumps during transportation, blocks the transportation pipeline, causes reduced transportation efficiency, and zinc subchloride overflows from the input port, the present invention provides a spoiler component 2. When zinc subchloride is transported, the first motor 231, the gear 232 and the gear ring 233 can be used to drive the rotating rod 21 to rotate, thereby driving the spiral spoiler blades 22 on the side wall of the rotating rod 21 to rotate. During the transportation of zinc subchloride, a spoiler treatment is performed on it to avoid the agglomeration of zinc subchloride. At the same time, gas can be pumped into the pump air box 25, and the gas is transported to the gas delivery cavity inside the rotating rod through the gas delivery pipe 26, and the gas is further discharged into the transportation pipeline 11 through the spoiler hole 24. Through the impact of the airflow on the zinc subchloride, the spoiler effect on the zinc subchloride is improved, and the agglomeration of zinc subchloride is further prevented, and the blockage in the transportation pipeline is prevented, thereby improving the transportation efficiency.

[0023] A conveying speed regulating component 3 is provided in the detection channel 12 and the pump air box 25, which is used to selectively increase or decrease the gas flow rate according to the conveying speed of the secondary zinc oxide. The conveying speed regulating component 3 includes an annular slide groove 31 opened on the inner wall of the detection channel 12, and an annular sliding plate 32 is slidably connected in the annular slide groove 31. A movable plate 33 is fixedly connected to the upper end of the annular sliding plate 32. A limiting groove 34 is provided on the outer wall of the detection channel 12. The movable plate 33 is slidably connected to the inner wall of the limiting groove 34, and a first spring 35 is provided between the movable plate 33 and the inner wall of the limiting groove 34. Two groups of sliding rheostats 36 controlled by the position of the movable plate 33 are provided on the outer wall of the detection channel 12. Both side walls of the pump air box 25 are provided with a plurality of sliding resistors 36. An air extraction pipe 37 is fixedly connected, one of which connects the pump air box 25 with the air supply channel 1, and the other air extraction pipe 37 connects the pump air box 25 with the outside world. A solenoid valve is provided in each of the air extraction pipes 37, and the solenoid valve is electrically connected to the power supply device through a sliding rheostat 36. A first non-return valve is provided in the air supply pipe 26. A pump air chamber 38 is fixedly connected on one side wall of the pump air box 25, and a piston block 39 is sealingly and slidably connected in the pump air chamber 38. A suction component 4 for driving the piston block 39 to move back and forth is also provided in the pump air chamber 38, and the suction component 4 is controlled by the sliding rheostat 36 to adjust the displacement of the piston block 39 when it moves back and forth, thereby adjusting the specific increase and decrease in the gas flow rate during the zinc hypochlorite transportation process.

[0024] Specifically, the sliding rheostat 36 includes two support rods 361 arranged on the outer wall of the detection channel 12, a resistance rod 362 is fixedly connected between the two support rods 361, a sliding plate 363 is slidably connected to the resistance rod 362, and a second spring 364 is provided between the sliding plate 363 and the side wall of the movable plate 33.

[0025] In view of the complexity of the interaction between the flow of zinc subchloride and the airflow in the prior art, it is difficult for the pneumatic conveying pump to accurately adjust the conveying speed of zinc subchloride, which further leads to the problem that the conveying speed of zinc subchloride is easily too fast or too slow. In the present invention, by setting a conveying speed adjustment component 3, the gas flow rate can be selectively increased or decreased according to the conveying speed of zinc subchloride during the conveying process. The specific increase or decrease is as follows: When the conveying speed of zinc hypochlorite is slow, the shear stress generated during the conveying of zinc hypochlorite flowing into the detection channel 12 is small, which drives the annular sliding plate 32 to be located on the left side of the annular sliding groove 31, so that the sliding piece 363 on the left side of the movable plate 33 is not located on the rightmost side of the resistance rod 362, so that the resistance of the circuit where the electromagnetic valve in the air extraction pipe 37 connecting the pump air box 25 with the outside world is located is not at the maximum value, and the current is not at the minimum value. The electromagnetic valve in the air extraction pipe 37 connecting the pump air box 25 with the outside world is in an open state, so that the pump air box 25 draws outside air and conveys it to the inside of the conveying pipeline 11 when pumping air, so as to assist the conveying of zinc hypochlorite, increase its conveying speed, and avoid blockage of the conveying pipeline due to the too slow conveying speed of zinc hypochlorite; When the conveying speed of zinc subchloride is faster, the shear stress generated by the zinc subchloride flowing into the detection channel 12 during conveying is relatively large, and the annular sliding plate 32 is in the right position in the annular sliding groove 31, so that the sliding piece 363 on the right side of the movable plate 33 is not in the leftmost position on the resistance rod 362, so that the resistance of the circuit where the electromagnetic valve in the exhaust pipe 37 connecting the pump air box 25 and the gas transmission channel 1 is located is not at the maximum value, and the current is not at the minimum value. The electromagnetic valve in the exhaust pipe 37 connecting the pump air box 25 and the gas transmission channel 1 is in an open state, so that the pump air box 25 extracts air from the gas transmission channel 1 when pumping air, and conveys it to the conveying pipeline 11, so that the gas flow at the gas transmission channel 1 is reduced, and the pumped gas weakens the driving force of the zinc subchloride after circulating through the pump air box 25, the gas transmission pipe 26, the gas transmission cavity and the spoiler hole 24, so that the conveying speed of zinc subchloride can be reduced, and the generation of a large number of bubbles caused by the excessively fast conveying speed of zinc subchloride can be avoided, thereby improving the product quality of the produced zinc subchloride.

[0026] The suction assembly 4 includes a reciprocating screw 41 rotatably connected to the inner wall of the pump air chamber 38, a lifting block 42 is threadedly connected to the reciprocating screw 41, the lifting block 42 is slidably connected to the inner wall of the pump air chamber 38, the side end of the lifting block 42 is fixedly connected to a support plate 43, the upper end of the support plate 43 is rotatably connected to a guide inclined plate 44 through a mounting seat, two electromagnetic springs 45 are provided between the guide inclined plate 44 and the upper end of the support plate 43, two sliding rheostats 36 are connected in parallel, one electromagnetic spring 45 is connected in series with one of the sliding rheostats 36, and the other electromagnetic spring 45 is connected in parallel with the other sliding rheostat 36, one end of the piston block 39 close to the guide inclined plate 44 is fixedly connected to a hinged rod 46, a guide wheel 47 is hinged on the hinged rod 46 and rolls in contact with the guide inclined plate 44, and a second motor 48 for driving the reciprocating screw 41 is fixedly connected to the outer wall of the pump air chamber 38.

[0027] Specifically, a return spring 5 is provided between the piston block 39 and the inner wall of the pump air box 25. Through the return spring 5, when the guide inclined plate 44 moves downward, the guide wheel 47 can be displaced along the guide inclined plate 44 under the action of the elastic force of the return spring 5, so that the guide wheel 47 can drive the piston plate 63 to move to the left side. When the guide inclined plate 44 moves upward, since the elastic force of the return spring 5 is much smaller than the elastic force of the electromagnetic spring 45, it will not compress the guide inclined plate 44, so that the guide wheel 47 can be displaced along the guide inclined plate 44 and drive the piston plate 63 to move to the right side, ensuring the reciprocating horizontal displacement of the piston plate 63.

[0028] In order to improve the accuracy of adjusting the conveying speed of zinc subchloride, the present invention sets a suction assembly 4. When the pump air box 25 pumps air, the reciprocating screw 41 can be driven to rotate by the second motor 48, thereby driving the lifting block 42 and the support plate 43 to perform reciprocating vertical displacement, and further causing the guide inclined plate 44 above them to perform reciprocating vertical displacement. Through the resistance of the guide inclined plate 44 to the guide wheel 47, the piston block 39 can perform reciprocating horizontal displacement in the pump air chamber 38 under the action of the guide wheel 47, thereby realizing continuous pumping of air, and the displacement of the piston block 39 in the pump air chamber 38 will show the following changes: In the process of the annular sliding plate 32 sliding from the left side to the middle, it means that the conveying speed of zinc subchloride increases to a suitable conveying speed under a relatively slow condition. In this process, the sliding of the left sliding piece 363 on the left resistance rod 362 increases the resistance of the sliding rheostat 36 connected in parallel with the electromagnetic spring 45, thereby reducing the resistance of the main circuit where the electromagnetic spring 45 is located, and the current tends to increase. Since the magnetic field strength generated when the current passes through the coil increases, the magnetic field exerts a greater force on the spring or the iron core. Therefore, when the current tends to increase, the deformation of the electromagnetic spring 45 increases, the elastic force increases, and the inclination angle of the guide inclined plate 44 on the support plate 43 increases, so that when the support plate 43 drives the guide inclined plate 44 to move vertically by the same amplitude, the amplitude of the horizontal displacement of the piston block 39 driven by the guide wheel 47 decreases, so that the conveying speed of zinc subchloride is closer to the suitable conveying speed, the amount of sucked external air is smaller, and the effect of assisting the conveying of zinc subchloride is lower; In the process of the annular sliding plate 32 sliding from the middle to the right side, it indicates that the conveying speed of zinc subchloride increases from a suitable conveying speed to a faster conveying speed. In this process, the sliding of the right sliding piece 363 on the right resistance rod 362 makes the resistance of the sliding rheostat 36 connected in series with the electromagnetic spring 45 tend to decrease, so that the resistance of the trunk where the electromagnetic spring 45 is located tends to increase, the current tends to decrease, and the elastic force of the electromagnetic spring 45 decreases, so that the inclination angle of the guide inclined plate 44 on the support plate 43 decreases, and then when the support plate 43 drives the guide inclined plate 44 to move vertically by the same amplitude, the guide wheel 47 drives the piston plate 63 to move horizontally by an increased amplitude, so that the conveying speed of zinc subchloride increases under faster conditions, and the more air is sucked into the air delivery channel 1, the greater the reduction in the conveying speed of zinc subchloride; During the zinc hypochlorite transportation process, the specific enhancement amount and reduction amount of the transportation speed can be adjusted in real time, and the zinc hypochlorite transportation speed can be adjusted more accurately, so as to further avoid the zinc hypochlorite transportation speed being too fast or too slow, so that the transportation speed is always maintained within an appropriate range, thereby improving the transportation efficiency and the stability of the zinc hypochlorite during the transportation process.

[0029] A stabilizing component 6 is also provided at one end of the detection channel 12 away from the conveying pipeline 11, which is used to improve the stability of zinc hypochlorite during the conveying process. The stabilizing component 6 includes an extraction cylinder 61 fixedly connected to the outer wall of one end of the detection channel 12, and the part of the rotating rod 21 extending into the extraction cylinder 61 is provided with a reciprocating threaded section 62, and a piston plate 63 is threadedly connected to the reciprocating threaded section 62. The piston plate 63 is horizontally slidably connected to the inner wall of the extraction cylinder 61, and a liquid storage tank 64 is fixedly connected to the outer wall of the detection channel 12 through a connecting rod. An extraction pipe 65 is fixedly connected between the liquid storage tank 64 and the extraction cylinder 61, and a discharge pipe 66 is fixedly connected between the extraction cylinder 61 and the conveying pipeline 11, and a second one-way valve is provided in the extraction pipe 65 and the discharge pipe 66.

[0030] Specifically, the second one-way valve is set so that when the piston plate 63 reciprocates horizontally in the extraction cylinder 61, the stabilizer in the liquid storage tank 64 can only be pumped into the extraction cylinder 61, and the stabilizer in the extraction cylinder 61 can only be pumped out into the delivery pipe 11, thereby ensuring automatic delivery of the stabilizer during the delivery process.

[0031] In order to prevent the zinc hypochlorite from decomposing during transportation, the present invention provides a stabilizing component 6. During the operation of the spoiler component, the rotation of the rotating rod 21 causes the piston plate 63 in the extraction cylinder 61 to reciprocate horizontally under the action of the reciprocating threaded section 62, thereby continuously pumping the stabilizer in the liquid storage tank 64 into the extraction cylinder 61, and continuously pumping the stabilizer in the extraction cylinder 61 out into the delivery pipe 11, so that the zinc hypochlorite maintains a longer stability period during storage and transportation.

[0032] The present invention can be explained by the following operation mode: During transportation, the raw material is transported to the transportation pipeline 11 through the feed port, the gas is transported to the gas transmission channel 1 through the pneumatic conveying pump, and the zinc hypochlorite is pushed in the transportation pipeline 11 by pneumatic means for transportation; The first motor 231, the gear 232 and the gear ring 233 drive the rotating rod 21 to rotate, thereby driving the spiral flow-turbulating blades 22 on the side wall of the rotating rod 21 to rotate, and perform flow turbulation on the zinc subchloride during the transportation process. The gas is pumped into the pump air box 25, and the gas is transported to the gas delivery cavity inside the rotating rod through the gas delivery pipe 26, and the gas is further discharged into the delivery pipeline 11 through the flow-turbulating hole 24. The impact of the airflow on the zinc subchloride improves the flow turbulation effect on the zinc subchloride. When the conveying speed of zinc hypochlorite is slow, the shear stress generated during the conveying of zinc hypochlorite is small, which drives the annular sliding plate 32 to be located in the left position of the annular chute 31, so that the solenoid valve in the air extraction pipe 37 connecting the pump air box 25 with the outside is opened, so that the pump air box 25 extracts the outside air and conveys it to the inside of the conveying pipe 11 when pumping air, thereby assisting the conveying of zinc hypochlorite; When the conveying speed of zinc subchloride is fast, the shear stress generated during the conveying of zinc subchloride is large, and the annular sliding plate 32 is located in the right position of the annular sliding groove 31, so that the solenoid valve in the air extraction pipe 37 connecting the pump air box 25 and the air delivery channel 1 is opened, so that the pump air box 25 extracts the air at the air delivery channel 1 when pumping air, and delivers it to the delivery pipeline 11, thereby reducing the driving force for zinc subchloride, thereby reducing the conveying speed of zinc subchloride; The rotation of the rotating rod 21 will cause the piston plate 63 in the extraction cylinder 61 to reciprocate horizontally under the action of the reciprocating threaded section 62, thereby continuously pumping the stabilizer in the liquid storage tank 64 into the extraction cylinder 61, and continuously pumping the stabilizer in the extraction cylinder 61 out into the delivery pipe 11.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
