Description

Technical Field

[0001] The invention relates to the technical field of suspension production, in particular to a pesticide suspension production device. Background Art

[0002] As is known, pesticide suspension is a type of pesticide formulation that can form a suspended state in water to improve the utilization rate and efficacy of the pesticide. The basic formula of the suspension mainly includes active ingredients, dispersants, adjuvants and carriers. Among them, the active ingredient is the main component of the pesticide, which can exert the insecticidal, weeding or bactericidal effects of the pesticide; the dispersant is the key component of the suspension, which can ensure the uniform distribution of particles in the suspension and prevent precipitation and stratification; the adjuvant can improve the particle coating rate and efficacy of the suspension; the carrier is the basis of the suspension, which can be water or an organic solvent.

[0003] The production process of pesticide suspension is as follows:

[0004] 1. Raw material preparation: According to the formula of pesticide suspension, prepare active ingredients, solvents, surfactants, adjuvants and other raw materials in a certain proportion;

[0005] 2. Mixing treatment: Add the prepared active ingredients into a container, add an appropriate amount of solvent to dissolve, then slowly add the dissolved active ingredient solution into an appropriate amount of surfactant solution and stir, then add other auxiliary agents into the suspending agent, adjust the concentration of the suspending agent, stir and force impact the prepared raw materials to fully mix the various ingredients;

[0006] 3. Filtration and refining: Filter the evenly mixed suspension through filtering equipment to remove impurities and particles;

[0007] 4. Packaging and storage: Fill and package the filtered suspension, and then store the packaged suspension.

[0008] Most of the filtering equipment for suspensions uses filters to filter them. Most of the filters use filter plates to filter the suspensions. The filter plates are used to filter and remove impurities from the suspensions to obtain pure suspensions.

[0009] For example, a patent with announcement number CN217661811U and announcement date of October 28, 2022, entitled "A suspension pesticide production filtering device", discloses a suspension pesticide production filtering device, including a filter, a filter element is installed inside the filter, the arc surface of the filter is fixedly connected to a circular tube, and four sliding rods are slidably inserted on the arc surface of the circular tube. The four sliding rods are grouped in pairs, and the ends of the two groups of sliding rods close to each other are fixedly connected to arc plates, and the arc surfaces of the same group of sliding rods are fixedly connected to fixed plates, and the sides of the two arc plates close to each other are fixedly connected to multiple cone blocks. The patent is a suspension pesticide production filtering device. By arranging sliding rods, arc plates, cone blocks, and plate brushes, when the staff takes the filter element out of the filter for cleaning, the sliding rod can drive the arc plate to move, so that the cone blocks and the plate brush can poke the circular holes on the surface of the filter element, thereby allowing the drug residues stuck tightly inside the filter element to fall out, which facilitates the cleaning of the filter element by the staff to a certain extent.

[0010] The deficiency of the prior art is that most of the suspension filters use filter plates to filter the suspension, and a small number of them use filter cloths to filter the suspension. When the filter cloths are arranged in the tank of the filter, they are mostly in a taut state, so that the filter cloths can better filter the suspension. When impurities remain on the filter cloths and need to be cleaned, the filter cloths are in a taut state. The taut state of the filter cloths is similar to that of filter plates made of hard materials, which will lead to incomplete cleaning of the filter plates or filter cloths by the cleaning unit, and impurities will remain on the filter plates or filter cloths, affecting the subsequent use of the suspension filter.

[0042] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.14 The present invention is further described in detail.

[0043] An embodiment provided by the present invention relates to a pesticide suspension production device, comprising a tank body 1 and a filter unit, wherein the tank body is provided with a filter unit, wherein the filter unit comprises an annular filter cloth 2, a positioning ring 7 and a positioning cylinder 3, wherein the bottom of the annular filter cloth 2 is limited to the bottom of the tank body 1 by the positioning cylinder 3, and the top of the annular filter cloth 2 is limited to the top of the tank body 1 by the positioning ring 7 so as to be axially movable;

[0044] It also includes a cleaning unit, which includes a driving member 4 and a cleaning brush 5. The driving member 4 drives the cleaning brush 5 to revolve around the center line of the tank body 1 to clean the annular filter cloth 2.

[0045] The annular filter cloth 2 has a vertically straight filtering state and a vertically loose cleaning state.

[0046] Specifically, the tank body 1 is a sealed tank for containing the positioning cylinder 3 and the annular filter cloth 2. The top of the tank body 1 is sealed and connected with a cover plate 6 through a flange. The annular filter cloth 2 is a filter medium woven from natural fibers or synthetic fibers. The annular filter cloth 2 is used for filtering operations in the production process of pesticide suspensions. The annular filter cloth 2 is an annular cylinder structure. A supporting member is provided at the bottom end of the tank body 1. The supporting member is used to carry the positioning cylinder 3. The supporting member and the bottom end of the positioning cylinder 3 are plugged and matched with each other to prevent the positioning cylinder 3 from rotating in the tank body 1. The cover plate 6 is provided with a driving member 4, and a cleaning brush 5 is installed at the output end of the driving member 4. The top of the positioning cylinder 3 is provided with an annular groove 8, and a positioning ring 7 is installed in the annular groove 8 in a sliding seal. The edge of the positioning ring 7 and the inner wall of the tank body are also slidingly sealed. A ring filter cloth 2 in a taut state is provided between the positioning ring 7 and the positioning cylinder 3. The bottom end of the ring filter cloth 2 is connected to the bottom end of the positioning cylinder 3, and the top end of the ring filter cloth 2 is connected to the positioning ring 7, so that the positioning ring 7 and the positioning cylinder 3 are in a tensioned state. The annular filter cloth 2 is stretched into a taut state, and a plurality of resilient members 9 are evenly arranged along the circumferential direction of the annular filter cloth 2 between the positioning ring 7 and the positioning cylinder 3 and on the outer side thereof. Each resilient member 9 is in a straight state under the tension of the positioning ring 7, and each resilient member 9 is a wavy structure in a natural state, that is, the resilient member 9 is a bent strip structure when not subjected to external force, and the resilient member 9 is deformed into a straight state under tension; a plurality of first threaded rods 1 are evenly installed along the circumferential direction of the positioning ring 7 in a rotationally matched manner at the top end thereof. 0, each first threaded rod 10 is threadedly connected to the cover plate 6; a water inlet pipe 11 and an air inlet pipe 12 are sequentially arranged on the side wall of one side of the tank body 1 from top to bottom, a first pressure gauge 13 for measuring the inlet pressure, a second pressure gauge 14 for measuring the outlet pressure and a water outlet pipe 15 are sequentially arranged on the side wall of the other side of the tank body 1 from top to bottom, a drain valve 16 is arranged at the bottom end of the tank body 1, and a drain pipe plugged with the drain valve 16 is arranged at the bottom end of the positioning cylinder 3, and the drain pipe is used to discharge impurities in the positioning cylinder 3;The positioning cylinder 3 is provided with a plurality of auxiliary channels 42 which are interconnected with the water inlet pipe 11, the air inlet pipe 12 and the water outlet pipe 15, so that the liquid (that is, clean water or suspension) in the water inlet pipe 11 can enter the annular filter cloth 2 on the positioning cylinder 3 from the auxiliary channels 42, and the liquid in the annular filter cloth 2 can be discharged from the tank body 1 through the auxiliary channels 42 through the water outlet pipe 15, and the gas in the air inlet pipe 12 can enter the annular filter cloth 2 on the positioning cylinder 3 from the auxiliary channels 42. The auxiliary channels 42 can facilitate the liquid (or gas) to enter (or be discharged from) the tank body 1. When the suspension needs to be filtered, the suspension is transported to the inner side of the positioning cylinder 3 and the annular filter cloth 2 through the water inlet pipe 11, and the liquid in the annular filter cloth 2 can be discharged from the tank body 1 through the annular filter cloth 2. The annular filter cloth 2 performs filtering operation on the suspension. At this time, the positioning ring 7 pulls the top of the annular filter cloth 2. Since the bottom of the annular filter cloth 2 is connected to the positioning cylinder 3, the annular filter cloth 2 is in a taut state (that is, the annular filter cloth 2 is in a vertically straight filtering state), so that impurities in the suspension remain in the annular filter cloth 2. Since an auxiliary channel 42 is provided between the outlet pipe 15 and the positioning cylinder 3, the filtered suspension is discharged from the positioning cylinder 3 and the tank body 1 through the auxiliary channel 42 and the outlet pipe 15, and the filtered suspension can be obtained. When the pressure of the first pressure gauge 13 and the second pressure gauge 14 reaches the set value (that is, the pressure difference between the water inlet pipe 11 and the water outlet pipe 15 reaches the set value ), at this time, the positioning ring 7 releases the tension on the top of the annular filter cloth 2. Under the action of the annular filter cloth 2's own gravity, the annular filter cloth 2 is in a vertically loose and clean state. At this time, the water inlet pipe 11 is used to transport clean water, and the water outlet pipe 15 is used to discharge sewage (the water inlet pipe 11 and the water outlet pipe 15 are provided with three-way valves, so that the water inlet pipe 11 can transport suspending agent and clean water, and the water outlet pipe 15 can discharge suspending agent and clean water, that is, one inlet of the three-way valve on the water inlet pipe 11 is used to transport clean water, and the other inlet is used to transport suspending agent, and one inlet of the three-way valve on the water outlet pipe 15 is used to discharge sewage, and the other inlet is used to discharge suspending agent), so that the clean water cleans the annular filter cloth 2, and at the same time , start the driving member 4 (driving member 4 is a device with an output end capable of forward and reverse motion, preferably a motor) to drive the cleaning brush 5 to rotate, so that the cleaning brush 5 performs a cleaning operation on the annular filter cloth 2. When the impurities in the annular filter cloth 2 are cleaned, open the drain valve 16, and discharge the impurities in the annular filter cloth 2 into the annular filter cloth 2 and the tank body 1 through the drain valve 16. Since the annular filter cloth 2 is made of a flexible material, when the cleaning brush 5 rotates to clean the annular filter cloth 2, the annular filter cloth 2 will move with the rotation of the cleaning brush 5, so that the cleaning brush 5 can perform a comprehensive cleaning operation on the annular filter cloth 2, thereby improving the cleaning quality of the annular filter cloth 2 and providing convenience for the subsequent use of the annular filter cloth 2. ;

[0047] When some impurities still remain on the inner wall of the annular filter cloth 2, the driving member 4 is closed to stop its rotation, and the staff simultaneously twists the first threaded rod 10 to rotate it on the cover plate 6 toward one end inside the tank body 1, so that the first threaded rod 10 drives the positioning ring 7 to slide toward one end inside the annular groove 8. Since the annular filter cloth 2 loses the straightening force provided by the positioning ring 7, the annular filter cloth 2 is in a loose state (that is, the annular filter cloth 2 is in a vertically loose and clean state), the rebound member 9 loses the straightening force provided by the positioning ring 7, and the rebound member 9 rebounds and deforms into a wavy structure, so that the rebound member 9 provides a certain support force for the annular filter cloth 2, so that the inner wall of the annular filter cloth 2 is in a curved and uneven state (such as Figure 7 , Figure 8 as well as Fig. 9 The cleaning brush 5 is then moved back and forth to clean the filter cloth 2, and the cleaning brush 5 is then moved back and forth to clean the filter cloth 2.

[0048] When the cleaning operation of the annular filter cloth 2 is completed, the staff simultaneously twists the first threaded rod 10 to rotate it on the cover plate 6 toward the outer end of the tank body 1, so that the first threaded rod 10 drives the positioning ring 7 to slide toward the outer end of the annular groove 8. Since the annular filter cloth 2 is stretched by the positioning ring 7, the annular filter cloth 2 is in a taut state (that is, the annular filter cloth 2 is in a vertically straight filtering state), which facilitates the filtering operation of the annular filter cloth 2 on the suspended agent. The rebound member 9 is stretched by the positioning ring 7 again, so that the rebound member 9 is deformed into a straight state by the tension, so that the rebound member 9 will not affect the filtering operation of the annular filter cloth 2 on the suspended agent.

[0049] The deficiency of the prior art is that most of the suspension filters use filter plates to filter the suspension, and a small number of them use filter cloths to filter the suspension. When the filter cloths are arranged in the tank of the filter, they are mostly in a taut state, so that the filter cloths can better filter the suspension. When impurities remain on the filter cloths and need to be cleaned, the filter cloths are in a taut state. The taut state of the filter cloths is similar to that of filter plates made of hard materials, which will lead to incomplete cleaning of the filter plates or filter cloths by the cleaning unit, and impurities will remain on the filter plates or filter cloths, affecting the subsequent use of the suspension filter.

[0050] The beneficial effect of this embodiment is that when filtering the suspension, the annular filter cloth 2 is in a vertically straight filtering state, and the suspension is filtered by the annular filter cloth 2 so that impurities in the suspension can remain in the annular filter cloth 2. When there are many impurities in the annular filter cloth 2, the annular filter cloth 2 is in a vertically loose cleaning state, and the driving member 4 drives the cleaning brush 5 to revolve around the center line of the tank body, so that the cleaning brush 5 cleans the annular filter cloth 2. Since the annular filter cloth 2 is in a vertically loose state, the cleaning brush 5 can drive the annular filter cloth 2 to shake or vibrate to a certain extent when it rotates, so that the impurities remaining on the annular filter cloth 2 can be shaken away from the annular filter cloth 2, so that the cleaning of the annular filter cloth 2 is more complete.

[0051] Furthermore, a plurality of first threaded holes 17 are evenly arranged in the annular groove 8 along the circumferential direction thereof, and each of the first threaded holes 17 is threadably engaged with its corresponding first threaded rod 10 .

[0052] Specifically, when the annular filter cloth 2 needs to be replaced, the positioning cylinder 3 and the annular filter cloth 2 need to be taken out from the tank body 1, and the staff simultaneously twists the first threaded rod 10 to rotate it on the cover plate 6 toward one end inside the tank body 1 until the first threaded rod 10 is screwed into the first threaded hole 17, so that the cover plate 6, the positioning ring 7 and the positioning cylinder 3 are connected into a whole (such as Figure 8 as well as Fig. 9 As shown in the figure, the staff uses a lifting tool to remove the cover plate 6 from the tank body 1, and then simultaneously removes the cover plate 6, the positioning ring 7, the positioning cylinder 3 and the annular filter cloth 2 from the tank body 1, making the replacement of the annular filter cloth 2 more convenient.

[0053] Furthermore, the cleaning unit also includes a driven roller 18, a driving member 4 is installed in the middle of the top end of the cover plate 6, the output end of the driving member 4 passes through the cover plate 6 to connect to the driven roller 18, and a plurality of first elastic members 19 are symmetrically arranged on the outer wall of the driven roller 18 along its axial direction, that is, a plurality of first elastic members 19 are arranged on the outer walls on both sides of the driven roller 18 along its axial direction, and the first elastic members 19 on both sides of the driven roller 18 are symmetrically arranged with respect to the axis of the driven roller 18, and each first elastic member 19 located on the same side of the driven roller 18 is commonly connected to a cleaning brush 5.

[0054] Specifically, when the annular filter cloth 2 needs to be cleaned, the annular filter cloth 2 is in a vertically loose cleaning state, the driving member 4 is started to drive the driven roller 18 to rotate, and the driven roller 18 drives the first elastic member 19 (the first elastic member 19 is an element that can be telescopic and reset, preferably an elastic telescopic rod) to rotate synchronously, and the first elastic member 19 drives the cleaning brush 5 to rotate. Since the first elastic member 19 has a certain elasticity, the cleaning brush 5 can perform a certain elastic pressing and rubbing on the annular filter cloth 2, thereby preventing the annular filter cloth 2 from being damaged due to excessive pressing force of the cleaning brush 5 on the annular filter cloth 2.

[0055] In another embodiment provided by the present invention, the cleaning unit also includes a square plate 20, and a plurality of first elastic members 19 are symmetrically arranged on the outer wall of the driven roller 18 along its axial direction, and each of the first elastic members 19 located on the same side of the driven roller 18 is commonly connected to a square plate 20, and an arc groove 21 is respectively provided on the two square plates 20, and each of the two arc grooves 21 is rotatably installed with a swing plate 23 through a positioning shaft 22, and a plurality of second elastic members 24 are evenly arranged on the side wall of one end of the two swing plates 23 located inside the arc groove 21, and each of the second elastic members 24 is connected to the inner wall of the arc groove 21.

[0056] Specifically, when the annular filter cloth 2 needs to be cleaned, the annular filter cloth 2 is in a vertically loose cleaning state, the driving member 4 is started to drive the driven roller 18 to rotate, the driven roller 18 drives the first elastic member 19 to rotate synchronously, the first elastic member 19 drives the square plate 20 to rotate, the square plate 20 drives the swing plate 23 to rotate, the swing plate 23 is made of rubber material, because the swing plate 23 is pressed against the annular filter cloth 2, when the annular filter cloth 2 is cleaned when the swing plate 23 rotates, the swing plate 23 is subjected to the pressing force of the annular filter cloth 2, so that the swing plate 23 is subjected to the pressing force of the annular filter cloth 2 while being subjected to the rotational thrust of the square plate 20, so that the swing plate 23 can rotate in the arc groove 21, when the swing plate 23 is in the arc groove 21, the swing plate 23 is in the arc groove 21, and the swing plate 23 is in the arc groove 21. When the cambered groove 21 rotates to a certain angle, the swing plate 23 provides a certain pulling force (or pushing force) for the second elastic member 24 (the second elastic member 24 is an element capable of telescopic reset, preferably a spring), so that the second elastic member 24 is in a stretched (or contracted) state. When the pressing force between the swing plate 23 and the annular filter cloth 2 is reduced, under the rebound action of the second elastic member 24, the swing plate 23 rotates and resets, so that the swing plate 23 can perform a certain reciprocating swing, so that the swing plate 23 drives the annular filter cloth 2 to perform a certain reciprocating swing, so that the impurities remaining on the annular filter cloth 2 can be swung off the annular filter cloth 2, thereby preventing the annular filter cloth 2 from remaining with impurities, and improving the cleaning efficiency of the annular filter cloth 2.

[0057] In another embodiment provided by the present invention, a plurality of first elastic members 19 are evenly arranged on the outer wall of the driven roller 18. In the axial direction of the driven roller 18, each of the first elastic members 19 is evenly arranged along the axial direction of the outer wall of the driven roller 18. A square plate 20 is commonly connected to each of the first elastic members 19 in the same axial direction. In the circumferential direction of the driven roller 18, each of the first elastic members 19 is evenly arranged along the circumference of the outer wall of the driven roller 18. Each of the square plates 20 is evenly arranged along the circumferential direction of the driven roller 18. Each of the square plates 20 has an arc groove formed thereon. 21, each of the arc grooves 21 is rotatably mounted with a cleaning round roller 25 through a positioning shaft 22, the top of each of the positioning shafts 22 in the square plate 20 penetrates the square plate 20 and is connected to a driven gear 26, and the top of each of the square plates 20 is rotatably mounted with a transmission gear 27, and each of the transmission gears 27 is respectively meshed with its corresponding driven gear 26, and the top of the positioning cylinder 3 is uniformly provided with a plurality of through grooves 28 along its circumferential direction, and an auxiliary circular tube 29 is arranged in the positioning cylinder 3, and a plurality of The part of the positioning cylinder 3 between its inner wall and the auxiliary round tube 29 is uniformly provided with a plurality of straight plates 31 along its circumferential direction by means of sliding fit, and each of the straight plates 31 is uniformly provided with a plurality of rubber soft rods 32, and each of the rubber soft rods 32 is slidably arranged in the corresponding through hole 30, and each of the straight plates 31 and the inner wall of the positioning cylinder 3 are connected by a uniformly arranged third elastic member 33, and each of the straight plates 31 is provided with a sliding round rod 34 at the top, and each of the sliding round rods 34 is slidably arranged in the corresponding through groove 28. A plurality of connecting rods 35 are symmetrically mounted on the outer wall of the driven roller 18 in a rotationally matched manner, and an inner ring gear 36 is commonly connected to the plurality of connecting rods 35, and the inner ring gear 36 is meshed with each of the transmission gears 27, and a plurality of fourth elastic members 37 are arranged on the outer wall of each of the square plates 20, and an active circular ring 38 is commonly connected between each of the fourth elastic members 37, and a fluctuation ring groove 39 is provided at the bottom end of the active circular ring 38, and each of the sliding circular rods 34 is slidably mounted in the fluctuation ring groove 39, and the fluctuation ring groove 39 is an annular groove with an uneven inner wall.

[0058] Specifically, when the annular filter cloth 2 needs to be cleaned, the annular filter cloth 2 is in a vertically loose cleaning state, the driving member 4 is started to drive the driven roller 18 to rotate, the driven roller 18 drives the first elastic member 19 to rotate synchronously, the first elastic member 19 drives the square plate 20 to rotate synchronously, the square plate 20 drives the cleaning round roller 25 to move, so that the cleaning round roller 25 cleans the annular filter cloth 2. At the same time, since the connecting rod 35 is rotatably arranged on the outer wall of the driven roller 18, the connecting rod 35 is connected to the inner ring gear 36. When the driven roller 18 drives the square plate 20 to rotate through the first elastic member 19, the square plate 20 drives the driven gear 26 to rotate. Since each transmission gear 27 is meshed with the inner ring gear 36, when the square plate 20 drives the transmission gear 27 to rotate, the transmission gear 27 rotates under the meshing of the inner ring gear 36, so that the transmission gear 27 drives the driven gear 26 meshing with it to rotate, the driven gear 26 drives the positioning shaft 22 to rotate, and the positioning shaft 22 drives the cleaning roller 25 to rotate, so that the cleaning roller 25 rotates while following the rotation of the square plate 20 and driven by the driven gear 26 and the positioning shaft 22, so that the cleaning roller 25 can perform a comprehensive cleaning operation on the annular filter cloth 2. At the same time, the square plate 20 drives the active ring 38 to rotate. A fluctuation ring groove 39 is provided, and a sliding round rod 34 is slidably arranged in the fluctuation ring groove 39, so that when the active ring 38 rotates, the sliding round rod 34 slides along the track of the fluctuation ring groove 39. Since the fluctuation ring groove 39 is an annular groove with an uneven inner wall, the active ring 38 can drive the sliding round rod 34 to slide linearly reciprocatingly in the corresponding through groove 28 through the fluctuation ring groove 39, and the sliding round rod 34 drives the straight plate 31 to perform linear reciprocating motion. During the linear reciprocating motion of the straight plate 31, the third elastic member 33 (the third elastic member 33 is a component capable of telescopic reset, preferably a spring) is subjected to the linear reciprocating motion of the straight plate 31. The straight plate 31 drives the rubber rod 32 to perform linear reciprocating motion in the through hole 30, so that the rubber rod 32 can be pressed against the outer wall of the annular filter cloth 2, so that the annular filter cloth 2 can undergo a certain concave deformation. In the process of the cleaning roller 25 cleaning the annular filter cloth 2, the shape of the annular filter cloth 2 can undergo a certain deformation, so that when the cleaning roller 25 rotates to clean the annular filter cloth 2, the annular filter cloth 2 can vibrate to a certain extent, so that the impurities remaining on the annular filter cloth 2 can be shaken off the annular filter cloth 2, thereby improving the cleaning efficiency of the annular filter cloth 2.

[0059] In another embodiment provided by the present invention, a plurality of second threaded rods 40 are evenly arranged on the cover plate 6 along its circumferential direction in a threaded connection manner, a plurality of second thread grooves 41 are evenly arranged on the top end of the positioning cylinder 3 along its circumferential direction, and each of the second threaded rods 40 is threadably matched with its corresponding second thread groove 41.

[0060] Specifically, when the annular filter cloth 2 needs to be replaced, the positioning cylinder 3 and the annular filter cloth 2 need to be taken out from the tank body 1, and the staff simultaneously screws the second threaded rod 40 to rotate it on the cover plate 6 toward one end inside the tank body 1 until the first threaded rod 10 is screwed into the second threaded hole, so that the cover plate 6 and the positioning cylinder 3 are connected as a whole (such as Fig.14 As shown in the figure, the staff uses a lifting tool to remove the cover plate 6 from the tank body 1, and then simultaneously removes the cover plate 6, the positioning cylinder 3 and the annular filter cloth 2 from the tank body 1, making the replacement of the annular filter cloth 2 more convenient.

[0061] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
