Description

Technical Field

[0001] The invention relates to the technical field of suspended seed coating agent production, in particular to a filtering device used in the production process of suspended seed coating agent. Background Art

[0002] Suspended seed coating agent is a type of preparation used for seed coating and has film-forming properties. Suspended seed coating agent can not only standardize improved varieties, but also kill insects and bacteria, change the microenvironment around seeds, promote early germination and early maturity of plants, facilitate machine sowing, and break the dormancy period of seeds to achieve continuous sowing and other purposes. Suspended seed coating agent is a flowable, stable and uniform suspension made of active ingredients (insecticides, fungicides, plant growth regulators, trace elements, etc.), film-forming agents, wetting agents, dispersants, thickeners, warning colors, fillers and water. In the production process of suspended seed coating agent, it is necessary to go through the steps of batching, mixing, stirring, grinding, filtering and so on.

[0003] At present, when producing suspended seed coating agents, it is necessary to add thickeners and a variety of solid ingredients. It is easy for the thickener concentration to be too high or added too quickly, causing local violent thickening and forming granular clumps or flocculent clumps between the solid ingredients. It is easy to cause filter blockage when filtering the suspended seed coating agent. In addition, due to the viscous nature of the suspended seed coating agent itself, the screening speed of the suspended seed coating agent is slow. Because the mesh number of the screen for coating filtration is large, that is, the filtration degree is relatively fine, the viscous coating falls on the filter and cannot pass through the filter quickly like liquids such as clean water. The coating only falls through the sieve naturally by gravity, which greatly prolongs the overall filtration time and the filtration efficiency is very low. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For an embodiment of the present invention, please refer to Figures 1 to 13, comprising a box body 1, a support leg is arranged at the bottom of the box body 1, a control panel 6 is arranged on the front outer wall of the box body 1, a feeding assembly 3 is arranged in the middle of the top of the box body 1, a conical bottom plate 102 with a central upward protrusion is arranged at the bottom of the box body 1, and a discharge pipe 101 located above the conical bottom plate 102 is arranged on the outer side of the box body 1, such as Figure 8 and Fig. 9 As shown, the top edge of the conical bottom plate 102 is connected to the conical bottom net 112 through the bottom net support rods 111 arranged in a circumferential array, the top outer side of the conical bottom plate 102 is connected to the rotating outer cylinder 701 through a bearing, and the top inner side of the conical bottom plate 102 is connected to the rotating inner cylinder 109 through a bearing;

[0038] like Fig.12 and Fig.13 As shown, the middle part of the rotating inner cylinder 109 is connected to the inner cylinder net 702 in a cylindrical shape through the inner cylinder net rod 711, the top side wall of the rotating inner cylinder 109 is provided with inner spline plates 708 distributed in a ring array, the outer part of the inner spline plate 708 is sleeved with a rotating ring 707, the outer wall of the rotating ring 707 is connected to four rotating rods 705 through a bearing, the top inner wall of the rotating outer cylinder 701 is clamped with a clamping ring 706 through an outer spline plate 713, and the outer end of the rotating rod 705 is connected to the inner wall of the clamping ring 706;

[0039] like Figure 5 and Figure 8 As shown, a driving assembly 5 is arranged on one side of the top of the housing 1, and the driving assembly 5 includes a servo motor 501, the output end of the servo motor 501 is downwardly inserted into the top wall of the housing 1 and is keyed to a driving gear 502, a large gear ring 504 meshing with the driving gear 502 is arranged on the top side of the rotating outer cylinder 701, a gear ring 801 is arranged on the bottom inner wall of the rotating outer cylinder 701, a planetary gear 802 meshing with the gear ring 801 is connected to the top of the conical bottom plate 102 through a bearing, and a sun gear 803 meshing with the planetary gear 802 is arranged on the outer side wall of the rotating inner cylinder 109.

[0040] like Figure 5 and Figure 6 As shown, the feeding assembly 3 includes a cover 301 hingedly arranged on the top of the box body 1, a handle 302 is arranged on one side of the top of the cover 301, and a feeding hole 303 with a larger top and a smaller bottom is opened in the middle of the cover 301, and the bottom diameter of the feeding hole 303 is smaller than the diameter of the inner cylinder net 702.

[0041] When in use, the servo motor 501 is started through the control panel 6, and then Figure 5 and Figure 6As shown, the suspended seed coating agent to be filtered is added through the feeding hole 303, and after the servo motor 501 drives the driving gear 502 to rotate, since the driving gear 502 is meshed with the large gear ring 504, and the bottom of the rotating outer cylinder 701 is movably connected to the conical bottom plate 102 through the bearing, and the top of the rotating outer cylinder 701 is movably connected to the top wall of the box body 1 through the bearing, the rotating outer cylinder 701 can be driven to rotate by the driving gear 502, and at the same time, Figure 8 As shown, the outer wall of the rotating inner cylinder 109 is movably connected to the conical bottom plate 102 and the rotating outer cylinder 701 through the bearing, and as shown in FIG. Fig.12 As shown, the top is clamped in the rotating ring 707 through the inner spline plate 708 provided, and is movably connected to the rotating rod 705 through the bearing. Therefore, under the planetary gear mechanism composed of the gear ring 801, the planetary gear 802, and the sun gear 803, the rotating outer cylinder 701 and the rotating inner cylinder 109 can be rotated in opposite directions at the same time, and the angular velocity of the rotating inner cylinder 109 is greater than the angular velocity of the rotating outer cylinder 701. In addition, the inner cylinder net 702 is smaller than the mesh number of the outer cylinder net 710, which is convenient for the initial suspended seed coating agent to pass through the inner cylinder net 702, and at the same time, larger impurities can be intercepted inside the inner cylinder net 702. The suspended seed coating agent filtered by the inner cylinder net 702 is then filtered by the outer cylinder net 710 to prevent large impurities from causing large-scale blockage of the finer mesh of the outer cylinder net 710, thereby improving the filtering effect of the filter net. At the same time, when filtering, the inner cylinder net 702 and the outer cylinder net 710 are both rotating, and the internal suspended seed coating agent can be thrown out by centrifugal force, further increasing the filtering efficiency.

[0042] like Figure 2 , Figure 3 and Figure 8 As shown, the bottom inner wall of the box body 1 is fixedly connected to the middle column 104 through the bottom rods 103 distributed in a circular array, the top of the middle column 104 is fixedly connected to the bearing column 105, the inner wall of the bearing column 105 is connected to the tightening elastic member 106 through the bearing, and the top of the tightening elastic member 106 is fixedly connected to the rubber plugging member 107 for sealing the bottom of the rotating inner cylinder 109.

[0043] like Figure 8 and Fig.13 As shown, a reciprocating screw 108 is provided in the middle of the top of the intermediate column 104 and is vertically inserted into the rotating inner cylinder 109. A rubber plug 107 is sleeved on the outside of the reciprocating screw 108. A threaded portion is provided in the middle of the reciprocating screw 108 and is threadedly connected to a semi-cylinder 116. A semi-circular scraper 110 for cleaning the inside of the inner cylinder net 702 is provided on the outside of the semi-cylinder 116. A vertical groove 115 is provided on the inner wall of the inner cylinder net rod 711. A slider 114 that slides and limits in the groove 115 is provided on the outer side of the semi-circular scraper 110.

[0044] like Figure 6 As shown, a cross rod 304 is provided at the top of the inner wall of the feeding hole 303, and a positioning cap 305 is provided below the middle cross position of the cross rod 304. The positioning cap 305 is sleeved on the top of the reciprocating screw 108 to fix the upper end of the reciprocating screw 108.

[0045] In specific use, when the inner cylinder net 702 is driven to rotate by the power of the driving assembly 5, the reciprocating screw 108 does not rotate because the bottom of the reciprocating screw 108 is fixedly connected to the middle column 104, and the top of the reciprocating screw 108 is fixed by the positioning cap 305. When the inner cylinder net 702 and the inner cylinder net rod 711 rotate together, the semicircular scraper 110 can be rotated with the cooperation of the slider 114 and the slide groove 115. The inner wall of the semicircular cylinder 116 is provided with a side surface that contacts the reciprocating screw 108. When the semi-ball and semi-cylinder 116 cooperate with the thread groove and rotate around the reciprocating screw 108, the semi-cylinder 116 can move along the path of the thread groove to realize the up and down movement of the semi-circular scraper 110. In addition, there are two semi-circular scrapers 110, which are respectively arranged at the upper and lower ends of the reciprocating screw 108. When the inner cylinder net rod 711 rotates, the top semi-circular scraper 110 moves downward and the bottom semi-circular scraper 110 moves upward, thereby cleaning the granular agglomerates or flocculated agglomerates filtered out by the inner cylinder net 702;

[0046] After cleaning, due to the weight of the granular agglomerates or flocculated agglomerates themselves, when too much impurity is accumulated on the semicircular scraper 110, the gravity of the accumulated agglomerates will gradually increase, but the adhesion area with the semicircular scraper 110 will not increase too much. When the adhesion force is gradually less than the gravity, the accumulated agglomerates with a larger volume will fall from the semicircular scraper 110, and will eventually settle at the bottom of the rotating inner cylinder 109 and fall on the rubber plug 107, so that the substances cleaned from the inner cylinder net 702 are stored at the bottom of the rotating inner cylinder 109, ensuring that the inner cylinder net 702 has good filtering performance;

[0047] When it is necessary to clean the sediment at the bottom of the rotating inner cylinder 109, first cut off the power to the device to stop filtering. Since the bottom edge of the rubber plug 107 is larger than the outer wall of the rotating inner cylinder 109, the edge of the rubber plug 107 can be pressed down to move the rubber plug 107 downward. At this time, the bottom of the rotating inner cylinder 109 will be opened to discharge the stored sediment. After the discharge, the rubber plug 107 is released and the rubber plug 107 returns to its original position under the force of the tightening elastic member 106.

[0048] like Figure 4 , Figure 7 , Fig.11As shown, an outer cylinder net 710 is arranged in the middle of the rotating outer cylinder 701, and the outside of the outer cylinder net 710 is supported by four outer cylinder net rods 709, and cleaning rods 703 are arranged at equal intervals on the outside of the inner cylinder net rods 711 in the vertical direction, and a cleaning plate 704 for cleaning the inner wall of the outer cylinder net 710 is arranged at the end of the cleaning rod 703, and a T-shaped block is arranged at the end of the cleaning rod 703, and a sliding groove 700 cooperating with the T-shaped block is arranged on the side wall of the cleaning plate 704, and a bottom ring 712 is fixedly connected to the bottom of the inner cylinder net 702, and the top edge of the inner cylinder net 702 is pressed against the top of the rotating outer cylinder 701 by the clamping ring 706.

[0049] When in use, the outer cylinder net 710 with the bottom ring 712 is vertically placed into the outer cylinder net rod 709, and the top is pressed by the clamping ring 706. After the outer cylinder net 710 is installed, the cleaning plate 704 is vertically inserted so that the end of the cleaning rod 703 cooperates with the sliding groove 700, so that the edge of the cleaning rod 703 is in close contact with the inner wall of the outer cylinder net 710, so as to facilitate the cleaning of impurities on the inner wall of the outer cylinder net 710. When the inner cylinder net rod 711 is driven to rotate by the driving component 5, due to the setting of the planetary gear mechanism, the rotating outer cylinder 701 and the rotating inner cylinder 109 can rotate in different directions, so that the outer cylinder net 710 and the cleaning plate 704 can move quickly to clean up the impurities. After the impurities are precipitated, the rotating rod 705 is pulled out upward, and then the cleaning plate 704 is pulled out upward so that the bottom ring 712 that presses the outer cylinder net 710 at the bottom can be taken out, thereby cleaning the precipitated impurities.

[0050] like Figure 4 , Figure 7 and Fig. 9 As shown, spiral scrapers 113 are arranged in a circular array on the outer side of the bottom of the rotating outer cylinder 701, and the bottom of the spiral scraper 113 is in contact with the top of the conical bottom net 112, so as to clean the top of the conical bottom net 112. A notch is arranged on the edge of the spiral scraper 113 on the box body 1 to facilitate the discharge of impurities, and a waste box 2 is arranged on the outer wall of the box body 1 to collect impurities discharged from the notch.

[0051] The waste box 2 includes two upper and lower annular plates 201, which are respectively arranged on the upper and lower sides of the notch. The two annular plates 201 are supported and connected by support columns 204 distributed in a circular array. Two semicircular sealing plates 202 are arranged on the outer sides of the two annular plates 201, and the two semicircular sealing plates 202 are sealed and connected by connecting bolts 203.

[0052] During specific use, when the spiral scraper 113 is driven to rotate by the driving component 5, the bottom of the spiral scraper 113 can be close to the top of the conical bottom net 112 for cleaning. Since the spiral scraper 113 is in the shape of a coiled spring when viewed from above, its actual state is a spiral shape that fits the conical bottom net 112. After the suspended seed coating agent falling from the outer cylinder net 710 is filtered through the conical bottom net 112, the remaining impurities will be cleaned up by the spiral scraper 113, so that the impurities gradually enter the interior of the waste box 2 through the gap. After the impurities inside the waste box 2 are gradually accumulated, the two semicircular sealing sheets 202 are opened by loosening the connecting bolts 203 to clean out the internal impurities.

[0053] like Figure 1 , Figure 5 , Fig.10 As shown, a blower assembly 4 is provided on the top circumference of the housing 1, and the housing 1 includes a rotating cylinder 402 installed on the top wall of the housing 1 through bearings and distributed in a circular array, a filter layer 401 is provided on the top of the rotating cylinder 402, a fan blade 403 is provided inside the rotating cylinder 402, a small gear ring 505 is provided on the outer wall of the rotating cylinder 402, a speed-increasing gear 503 is meshed on the side of the driving gear 502, the speed-increasing gear 503 is meshed with the small gear ring 505, and adjacent small gear rings 505 are connected in power through an intermediate gear 506.

[0054] The speed increasing gear 503 is movably connected to the housing 1 at its upper and lower ends through bearings. The speed increasing gear 503 is composed of two gears, one large and one small. The small gear is meshed with the driving gear 502 , and the large gear is meshed with the small gear ring 505 .

[0055] During specific use, the driving gear 502 is driven to rotate by the servo motor 501, and after being accelerated by the speed-increasing gear 503, the small gear ring 505 is driven to rotate at a high speed, so that the rotating cylinder 402 is blown through the fan blades 403 inside the rotating cylinder 402 during rotation, and the suspended seed coating agent thrown onto the inner wall of the box body 1 is blown downward, so that the suspended seed coating agent quickly falls on the conical bottom net 112, and at the same time, the downward blowing of the air blowing component 4 can also make part of the air flow downward through the conical bottom net 112, so that the air accelerates the suspended seed coating agent to pass through the conical bottom net 112, thereby further suspending the seed coating agent to improve the filtration efficiency.

[0056] The specific steps and principles of this device are as follows:

[0057] First, install the outer cylinder net 710. After opening the cover 301, put the outer cylinder net 710 with one end of the bottom ring 712 into the outer cylinder net rod 709. After the bottom ring 712 falls to the lowest position, Fig.11 As shown, the cleaning plate 704 is inserted vertically downward, and the sliding groove 700 is ensured to be engaged with the end of the cleaning rod 703, and then Fig.12As shown, the clamping ring 706 cooperates with the outer spline plate 713, and the top edge of the outer cylinder net 710 is pressed by the clamping ring 706. At the same time, the inner wall of the rotating ring 707 cooperates with the inner spline plate 708, so that the outer cylinder net rod 709 and the inner cylinder net rod 711 can rotate relative to each other. After the outer cylinder net 710 and the cleaning plate 704 are installed, the cover 301 is closed;

[0058] Before filtering, the servo motor 501 is started and the speed of the servo motor 501 is adjusted through the control panel 6, such as Figure 5 As shown, since the servo motor 501 can drive the driving gear 502 to rotate, the driving gear 502 drives the large gear ring 504 and the speed-increasing gear 503 to rotate at the same time, and the power of the speed-increasing gear 503 is finally transmitted to the small gear ring 505 to rotate the rotating cylinder 402 and use the fan blades 403 to blow air inside the box body 1; at the same time, when the driving gear 502 drives the large gear ring 504 to rotate, the rotating outer cylinder 701 rotates, as shown in FIG. Figure 8 As shown, since the bottom of the rotating outer cylinder 701 drives the sun gear 803 to rotate through the gear ring 801 and the planetary gear 802, the rotating inner cylinder 109 can rotate in the opposite direction relative to the rotating outer cylinder 701 at a faster angular speed;

[0059] After the suspended seed coating agent to be filtered is added through the feeding hole 303 opened in the middle of the cover 301, the larger lumps in the suspended seed coating agent will be filtered out by the inner cylinder net 702, and the suspended seed coating agent after preliminary filtration will be thrown out from the inside of the inner cylinder net 702. After entering the inside of the outer cylinder net 710, it will be filtered again to block the smaller impurities in the suspended seed coating agent on the outer cylinder net 710. After the suspended seed coating agent is thrown out, part of the suspended seed coating agent will remain on the inner wall of the box body 1, and will flow downward rapidly under the blowing of the air blowing component 4, and finally fall on the top of the conical bottom net 112, and gradually flow along the inclined surface of the conical bottom net 112. In the process of flowing, it is continuously filtered by the conical bottom net 112, and at the same time, part of the air blown downward by the air blowing component 4 will also pass through the conical bottom net 112, thereby accelerating the further filtering of the suspended seed coating agent by the conical bottom net 112, and finally the filtered suspended seed coating agent will flow out from the discharge pipe 101 and be collected;

[0060] When filtering the suspended seed coating agent, since the bottom of the reciprocating screw 108 is fixedly connected to the middle column 104, the reciprocating screw 108 does not rotate, and the top of the reciprocating screw 108 is fixed by the positioning cap 305. When the inner cylinder net 702 and the inner cylinder net rod 711 rotate together, the semicircular scraper 110 can be rotated with the cooperation of the slider 114 and the slide groove 115. The side of the inner wall of the semicircular cylinder 116 that contacts the reciprocating screw 108 is provided with a semicircular scraper 110 that cooperates with the thread groove. When the ball and the semi-cylinder 116 rotate around the reciprocating screw 108, the semi-cylinder 116 can move along the path of the thread groove to realize the up and down movement of the semi-circular scraper 110. In addition, there are two semi-circular scrapers 110, which are respectively arranged at the upper and lower ends of the reciprocating screw 108. When the inner cylinder net rod 711 rotates, the top semi-circular scraper 110 moves downward, and the bottom semi-circular scraper 110 moves upward, thereby cleaning the granular agglomerates or flocculated agglomerates filtered out by the inner cylinder net 702;

[0061] After cleaning, due to the weight of the granular agglomerates or flocculated agglomerates themselves, when too much impurity is accumulated on the semicircular scraper 110, the gravity of the accumulated agglomerates will gradually increase, but the adhesion area with the semicircular scraper 110 will not increase too much. When the adhesion force is gradually less than the gravity, the accumulated agglomerates with a larger volume will fall from the semicircular scraper 110, and will eventually settle at the bottom of the rotating inner cylinder 109 and fall on the rubber plug 107, so that the substances cleaned from the inner cylinder net 702 are stored at the bottom of the rotating inner cylinder 109, ensuring that the inner cylinder net 702 has good filtering performance;

[0062] When it is necessary to clean the sediment at the bottom of the rotating inner cylinder 109, first ensure that the device is powered off and the suspended seed coating agent to be filtered is no longer added, so that the entire device stops filtering. Since the bottom edge of the rubber plug 107 is larger than the outer wall of the rotating inner cylinder 109, the edge of the rubber plug 107 can be pressed down to move the rubber plug 107 downward. At this time, the bottom of the rotating inner cylinder 109 will be opened to discharge the stored sediment. After the discharge, the rubber plug 107 is released and the rubber plug 107 returns to its original position under the force of the tightening elastic member 106.

[0063] At the same time, due to the setting of the planetary gear mechanism, the rotating outer cylinder 701 and the rotating inner cylinder 109 can rotate in different directions, so that the outer cylinder net 710 and the cleaning plate 704 can move quickly to clean up the impurities;

[0064] After too much impurity has been precipitated, first ensure that the device is powered off and no more suspended seed dressing agent to be filtered is added, so that the entire device stops filtering, pull out the rotating rod 705 upward, and then pull out the cleaning plate 704 upward, so that the bottom ring 712 that presses the outer cylinder net 710 at the bottom can be taken out, thereby cleaning the sediment;

[0065] Moreover, when the spiral scraper 113 is driven to rotate by the driving assembly 5, the bottom of the spiral scraper 113 can be closely attached to the top of the conical bottom net 112 for cleaning. Since the spiral scraper 113 is in the shape of a coiled spring when viewed from above, it is actually in the shape of a spiral that fits the conical bottom net 112. After the suspended seed coating agent falling from the outer cylinder net 710 is filtered by the conical bottom net 112, the remaining impurities will be cleaned up by the spiral scraper 113, so that the impurities gradually enter the interior of the waste box 2 through the gap.

[0066] When too much impurity gradually accumulates inside the waste box 2 and the inside of the waste box 2 needs to be cleaned, first ensure that the device is powered off and no more suspended seed dressing agent to be filtered is added, so that the entire device stops filtering, and the two semicircular sealing sheets 202 are opened by loosening the connecting bolts 203 to clean out the impurities inside. After cleaning, the two semicircular sealing sheets 202 are reinstalled and filtering can be carried out again.
