Description

Technical Field

[0001] This invention relates to the field of biodiesel storage, and particularly to a biodiesel production and storage device. Background Technology

[0002] Biodiesel refers to fatty acid methyl esters or ethyl esters formed by esterification of vegetable oil, animal oil, waste oil or microbial oil with methanol or ethanol. It is a typical "green energy". The biodiesel produced is mostly stored in tank containers and then transported as a whole to the destination for use.

[0003] Containers used for storing biodiesel need to be internally cleaned before use to prevent rust, impurities, etc. from being present on the inner surface of the container, which would reduce the purity of the biodiesel and prevent biodiesel with impurities from affecting the operation of the equipment. However, if the cleaning is not done properly, the overall cleaning operation will not be very effective.

[0004] In addition, containers used to store biodiesel must have high sealing properties to prevent unnecessary contact between the diesel and air, which could lead to oxidation. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a biodiesel production and storage device, including a storage tank, which consists of a tank body and a cap. The cap is installed on the upper end of the tank body by means of a threaded connection. A cleaning part is provided at the upper end of the tank body, and a suction part is arranged on the right side of the tank body.

[0006] The upper surface of the tank body has threaded holes evenly distributed around the circumference of the tank body. An electric push rod is installed in each threaded hole via a threaded connection. The upper end of the electric push rod is rotatably connected to the lower end of the same circular ring plate. A vertical frame is arranged at the center of the circular ring plate. Symmetrical mating plates are installed on the upper end of the vertical frame, with their opposite ends slidably connected to the inner ring surface of the circular ring plate. A square electric slider is installed on the vertical frame. Side blocks are provided on all four sides of the square electric slider. An arc-shaped electric slider is installed on the end of each side block facing away from the vertical frame. A connecting shaft is located on the end of the arc-shaped electric slider facing away from the side blocks. A cleaning section is located on the end of the connecting shaft facing away from the side blocks. The cleaning section includes a rectangular block, an arc-shaped plate, an arc-shaped grinding plate, an auxiliary grinding plate, a push rod, an inverted U-shaped plate, a conveying electric slider, and a circular... The rectangular block is connected to one end of the connecting shaft and the opposite side block by a threaded connection. An arc-shaped plate is installed on the other end of the rectangular block. An arc-shaped grinding plate is installed on the lower end of the outer arc surface of the arc-shaped plate. An auxiliary grinding plate with a vertical triangular cross-section is provided on the upper end of the arc-shaped plate. The end of the auxiliary grinding plate near the outer arc surface of the arc-shaped plate has a pointed structure and is inclined upward. Two ear plates are arranged between the arc-shaped plate and the side block. The rectangular block is located between the two ear plates. A plug rod is engaged between the upper end of the ear plate and the rectangular block. An inverted U-shaped plate is installed between the lower ends of the ear plates on the same side. The inverted U-shaped plate is below the side block. A conveying electric slider is installed inside the inverted U-shaped plate. A circular grinding plate is installed at the lower end of the conveying electric slider. The outer ring surface of the circular grinding plate and the outer arc surface of the arc-shaped grinding plate are on the same vertical plane.

[0007] With the tank fixed to the ground, the inside of the tank is first cleaned by the cleaning unit. After the cleaning is completed, the cleaning unit is detached from the tank. Then, the impurities are removed by manual labor in conjunction with the suction unit. Biodiesel is then poured into the tank, and finally the cap is installed, and the biodiesel is stored in a sealed container.

[0008] The suction unit includes a vacuum cleaner, a suction hose, a main suction plate, and side suction plates. The upper end of the vacuum cleaner is connected to the suction hose, which is assembled from two equal-length rigid and flexible hoses. The lower end of the rigid hose section is fitted with the main suction plate, which has a square structure. Side suction plates are provided on all four sides of the main suction plate. The upper end of the side suction plates is connected to the suction hose by a side tube. The side suction plates facing away from the main suction plate and the lower end of the main suction plate are both open structures. After polishing and cleaning, the electric push rod is manually removed from the tank. The cleaning unit and vertical frame are completely detached from the tank. Then, the main suction plate and side suction plates are suspended inside the tank by manually holding the rigid section of the suction hose, and the main suction plate and side suction plates are moved downward at a relatively uniform speed. At the same time, the vacuum cleaner works. The side suction plates are mainly used to remove impurities that have been removed from the inner ring of the tank, while the main suction plate is mainly used to remove impurities that have been removed from the bottom wall of the tank. This multi-directional suction can speed up the removal of impurities and also prevent impurities from being left in the tank again.

[0009] Preferred technical solution one: The upper end of the side block is provided with a vertical circular hole, and the upper surface of the square electric slider is equipped with an extension fixing plate on all four sides. The upper surface of the extension fixing plate is provided with a circular through hole, which is arranged at equal intervals along the length of the extension fixing plate. The vertical circular hole and the corresponding circular through hole are connected by a shaft through a threaded connection. The installation position of the shaft is adjusted by manually removing and installing the shaft. As the installation position of the shaft changes, the diameter of the circular structure formed by the arc-shaped grinding plate changes synchronously. Based on this, the cleaning unit can be used for internal cleaning of tanks with different inner diameters within a certain range, and the effective utilization rate of the cleaning unit and its connected structure as a whole is improved.

[0010] Preferred technical solution two: An L-shaped plate is arranged above the arc-shaped electric slider. The horizontal section of the L-shaped plate is rotatably mounted on the upper end of the side block via a pin. An extension fixing plate is located between the vertical frame and the L-shaped plate. The lower end face of the vertical section of the L-shaped plate is connected to the upper end face of the rectangular block via a magnetic layer. Before rotating the rectangular block, the L-shaped plate is manually lifted upwards, and the L-shaped plate rotates around the pin it is connected to until the L-shaped plate no longer obstructs the rotation of the rectangular block. Then, the rectangular block is manually rotated, and the arc-shaped plate drives the auxiliary grinding plate to move synchronously. After the arc-shaped plate is rotated 180 degrees, the auxiliary grinding plate faces downwards. Then, the L-shaped plate is manually rotated back to its original state. The L-shaped plate can play an additional role in stabilizing the position of the arc-shaped plate, preventing the arc-shaped plate from deflecting after rotation and affecting the auxiliary grinding work.

[0011] Preferred technical solution three: The connecting shaft and the end of the arc-shaped electric slider opposite to the side block are connected by a threaded engagement. The threads at both ends of the connecting shaft are in opposite directions. With the threads at both ends of the connecting shaft in opposite directions, the connecting shaft and the arc-shaped electric slider remain tightly connected during the manual rotation of the rectangular block. When the worker rotates the connecting shaft to disengage it from the arc-shaped electric slider, the entire cleaning part can be removed, which facilitates the specific inspection or cleaning of the cleaning part.

[0012] Preferred technical solution four: The auxiliary grinding plate is equipped with an overlapping plate at one end near the side block. The end of the overlapping plate away from the auxiliary grinding plate is connected to the upper end of the rectangular block by connecting bolts. When the grinding end of the auxiliary grinding plate is worn to a large extent, the grinding end of the auxiliary grinding plate cannot contact the inner wall of the tank and therefore cannot be ground. At this time, the connecting bolts can be manually removed to replace the entire auxiliary grinding plate and overlapping plate.

[0013] Preferred technical solution five: The vertical cross-section of the cover is T-shaped. Mounting plates are symmetrically installed on the lower end face of the horizontal section of the cover. The tank body is located between the mounting plates. Arc-shaped elastic plates are installed on opposite sides of the mounting plates. A rubber band connects the opposite ends of the elastic plates. The upper end faces of both the elastic plates and the rubber band are in contact with the lower end face of the horizontal section of the cover. In its natural state, the diameter of the complete circular structure formed by the elastic plates and the rubber band is smaller than the outer diameter of the tank body. When the cover is manually installed, the elastic plates and the rubber band are both clamped onto the tank body, and both are in a stretched state. In this state, the connection between the elastic plates and the rubber band and the outer ring surface of the tank is very tight, thus greatly improving the overall sealing performance of the storage tank.

[0014] Preferred technical solution six: A brush is installed at the upper end of the outer arc surface of the arc plate. The brush is evenly distributed along the arc direction of the arc plate and can move synchronously with the arc plate. The function of the brush is to clean the polished parts of the inner wall of the tank to prevent the removed impurities from re-attaching to the inner ring surface of the tank.

[0015] Preferred technical solution seven: A pin is rotatably connected to one end of the side suction plate near the main suction plate. Both ends of the pin connected to the side suction plate are connected to the main suction plate with lugs. The side suction plate is placed between two L-shaped hanging plates, with the lower end face of the side suction plate contacting the upper end face of the horizontal section of the hanging plate. A T-shaped plate connects the upper ends of the hanging plates on the same side. A vertical electric slider is installed at the end of the T-shaped plate away from the hanging plate. The vertical electric slider is installed on the vertical side end of the sleeve block. The sleeve block is fitted onto the rigid section of the suction pipe. The sleeve block is located on the side... Above the pipe, as the side suction plate and the main suction plate are moved downwards synchronously inside the tank by manual operation, when the side suction plate approaches the bottom wall of the tank, the T-shaped plate is driven downwards by the vertical electric slider. The T-shaped plate drives the hanging plate to move synchronously. Under the action of gravity, the side suction plate rotates downwards around the pin shaft it is connected to, but the side suction plate always rests on the horizontal section of the hanging plate. The side suction plate in the inclined state can remove impurities accumulated at the edge of the bottom wall of the tank, and the suction range of the suction unit is further expanded, avoiding the occurrence of suction dead corners.

[0016] Preferred technical solution eight: An embedded plate is installed inside the lower end of the main dust suction plate. A ventilation groove is opened at the lower end of the embedded plate. The upper ends of the ventilation grooves at both ends of the embedded plate are inclined towards the center of the embedded plate. The advantage of designing the ventilation groove as an inclined structure is that it expands the suction range of the main dust suction plate and shortens the time required for impurities to be completely removed.

[0017] The present invention has the following beneficial effects: 1. The cleaning part designed in the present invention can simultaneously polish the inner ring surface and the inner bottom wall of the tank, and can also polish the connection between the inner ring surface and the inner bottom wall of the tank, so as to make the inner wall of the tank fully polished and improve the one-time cleaning effect of the tank. At the same time, the cleaning part as a whole can move down along the vertical plane and swing back and forth along the horizontal plane, thereby greatly improving the polishing effect of the inner ring surface of the tank through this dual movement.

[0018] 2. The side suction plate in this invention is mainly for removing impurities that have been removed from the inner circumference of the tank, while the main suction plate is mainly for removing impurities that have been removed from the bottom wall of the tank. This multi-directional suction can speed up the removal of impurities and also prevent impurities from being left in the tank again.

[0019] 3. The diameter of the circular structure formed by the arc-shaped grinding plate in this invention can be adjusted. Based on this, the cleaning unit can be used for internal cleaning of tanks with different inner diameters within a certain range, and the effective utilization rate of the cleaning unit and its connected structure as a whole is improved.

[0020] 4. The elastic plate and rubber band in this invention can be tightly fitted onto tanks of different outer diameters. Both can improve the tightness of the connection between the cap and the tank, thereby improving the overall sealing performance of the storage tank.

[0021] 5. The side suction plate in this invention adopts a rotatable structure, which is intended to remove impurities accumulated at the edge of the bottom wall of the tank by means of the rotatability of the side suction plate, thereby further expanding the suction range of the suction unit and avoiding suction dead corners.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] See Figure 1 , Figure 2 and Figure 3 A biodiesel production and storage device includes a storage tank 1, which consists of a tank body 10 and a cover 11. The cover 11 is installed on the upper end of the tank body 10 by means of threaded connection. A cleaning part 12 is provided on the upper end of the tank body 10, and a suction part 13 is arranged on the right side of the tank body 10.

[0039] See Figure 1 and Figure 3 The vertical cross-section of the cover 11 is T-shaped. Mounting plates 110 are symmetrically installed on the lower end face of the horizontal section of the cover 11. The tank body 10 is located between the mounting plates 110. An arc-shaped elastic plate 111 is installed on the opposite side of the mounting plates 110. A rubber strip 112 is connected between the opposite ends of the elastic plates 111. The upper end face of the elastic plate 111 and the upper end face of the rubber strip 112 are in contact with the lower end face of the horizontal section of the cover 11. In its natural state, the diameter of the complete circular structure formed by the elastic plate 111 and the rubber strip 112 is smaller than the outer diameter of the tank body 10. When the cover 11 is installed manually, the elastic plate 111 and the rubber strip 112 are both clamped on the tank body 10 and are in a stretched state. In this state, the connection between the elastic plate 111 and the rubber strip 112 and the outer ring surface of the tank body 10 is tight, thereby greatly improving the overall sealing performance of the storage tank 1.

[0040] See Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The upper end face of the tank body 10 is provided with threaded holes, which are evenly distributed around the circumference of the tank body 10. An electric push rod 100 is installed in the threaded hole by means of threaded engagement. The upper end of the electric push rod 100 is rotatably connected to the lower end of the same annular plate 101. A vertical frame 102 is arranged at the center of the annular plate 101. A connecting plate 103 is symmetrically installed at the upper end of the vertical frame 102. The opposite ends of the connecting plates 103 are slidably connected to the inner ring surface of the annular plate 101. A square electric slider 1 is installed on the vertical frame 102. 04. The square electric slider 104 has side blocks 105 on all four sides. An arc-shaped electric slider 106 is mounted on one end of the side block 105 facing away from the vertical frame 102. A connecting shaft 107 is located on the end of the arc-shaped electric slider 106 facing away from the side block 105. A cleaning section 12 is located on the end of the connecting shaft 107 facing away from the side block 105. The cleaning section 12 includes a rectangular block 120, an arc-shaped plate 121, an arc-shaped grinding plate 122, an auxiliary grinding plate 123, a rod 124, an inverted U-shaped plate 125, and a conveyor electric motor. The slider 126 and the circular grinding plate 127, one end of the rectangular block 120 are connected to the connecting shaft 107 and the end of the side block 105 opposite to it by a threaded connection, the other end of the rectangular block 120 is equipped with an arc-shaped plate 121, the lower end of the outer arc surface of the arc-shaped plate 121 is equipped with an arc-shaped grinding plate 122, the upper end surface of the arc-shaped plate 121 is provided with an auxiliary grinding plate 123 with a vertical cross-section of a triangle, the end of the auxiliary grinding plate 123 near the outer arc surface of the arc-shaped plate 121 is a pointed structure and tilted upwards, the arc-shaped plate 121 and the side block Two ear plates are arranged between 105, and a rectangular block 120 is located between the two ear plates. A plug rod 124 is snapped between the upper end of the ear plate and the rectangular block 120. An inverted U-shaped plate 125 is installed between the lower ends of the ear plates on the same side. The inverted U-shaped plate 125 is located below the side block 105. A conveying electric slider 126 is installed inside the inverted U-shaped plate 125. A circular grinding plate 127 is installed at the lower end of the conveying electric slider 126. The outer ring surface of the circular grinding plate 127 and the outer arc surface of the arc-shaped grinding plate 122 are on the same vertical plane.

[0041] With the tank 10 fixed to the ground, the interior of the tank 10 is first cleaned by the cleaning unit 12. After cleaning, the cleaning unit 12 is detached from the tank 10, and then the impurities are removed manually in conjunction with the suction unit 13. Biodiesel is then poured into the tank 10, and finally, the cap 11 is installed, sealing the biodiesel for storage. The specific process of cleaning the interior of the tank 10 by the cleaning unit 12 is as follows: The electric push rod is manually connected to the threaded hole, at which point the vertical frame 102 is located at the center of the tank 10. Then, the electric push rod drives the annular plate 101 downwards to adjust the distance between the lower end of the vertical frame 102 and the inner bottom wall of the tank 10. Finally, the lower end of the vertical frame 102 is a certain distance from the inner bottom wall of the tank 10. Then, the square electric slider 104 drives the side block 105 downwards along the vertical frame 102. The arc-shaped electric slider 106 and the cleaning unit 12 move synchronously, and the outer edge of the arc-shaped grinding plate 122... After the arc surface contacts the inner ring surface of the tank 10, the square electric slider 104 continues to move downwards, while the arc-shaped electric slider 106 drives the rectangular block 120 to reciprocate along the horizontal plane. The arc-shaped grinding plate 122 moves synchronously, and the arc-shaped grinding plate 122 polishes the inside of the tank 10 to remove impurities attached to the inner ring surface of the tank 10, so as to avoid impurities reducing the purity of biodiesel. With the cooperation between the square electric slider 104 and the arc-shaped electric slider 106, the arc-shaped grinding plate 122 can move downwards along the vertical plane and reciprocate along the horizontal plane. This dual movement greatly improves the polishing effect of the inner ring surface of the tank 10.

[0042] The circular grinding plate 127 and the inverted U-shaped plate 125 move synchronously with the arc-shaped grinding plate 122. When the circular grinding plate 127 contacts the inner bottom wall of the tank 10, the square electric slider 104 stops moving, and the arc-shaped electric slider 106 continues to drive the rectangular block 120 to perform reciprocating oscillating motion. The inverted U-shaped plate 125 and the circular grinding plate 127 oscillate synchronously. At the same time, the circular grinding plate 127 is driven to move along the inverted U-shaped plate 125 toward the vertical frame 102 by the conveying electric slider 126. The circular grinding plate 127 grinds the inner bottom wall of the tank 10. During the operation of the circular grinding plate 127 and the arc-shaped grinding plate 122, the work... The operator rotates the docking plate 103 to make the vertical frame 102 and the cleaning section 12 rotate synchronously, so as to improve the comprehensiveness of the grinding of the inner ring surface and the inner bottom wall of the tank 10. When the movement state of all the circular grinding plates 127 is consistent, the center of the inner bottom wall of the tank 10 will be in a state that has not been ground. At this time, the basic grinding of the inner bottom wall of the tank 10 is completed. Only a single conveying electric slider 126 drives the circular grinding plate 127 connected to it to move towards the center of the inner bottom wall of the tank 10. The circular grinding plate 127 is made to reciprocate and swing through the arc-shaped electric slider 106 to complete the comprehensive grinding of the inner bottom wall of the tank 10.

[0043] After the inner wall of the tank 10 is polished, the cleaning section 12 is moved upward by the square electric slider 104 until the cleaning section 12 is outside the tank 10. Then, the insert rod 124 is manually pulled out, and the inverted U-shaped plate 125 and the circular grinding plate 127 are removed as a whole. Next, the rectangular block 120 and the arc plate 121 are manually rotated as a whole until the arc plate 121 is flipped over. At this time, the auxiliary grinding plate 123 faces downward. Then, the square electric slider 104 moves the arc plate 121 and the auxiliary grinding plate together. 123 move downwards together. When the auxiliary grinding plate 123 contacts the connection between the inner ring surface and the inner bottom wall of the tank 10, the square electric slider 104 stops moving. Next, the arc-shaped electric slider 106 makes the auxiliary grinding plate 123 swing back and forth along the horizontal plane. At the same time, the worker rotates the docking plate 103 to make the vertical frame 102 and the cleaning part 12 rotate synchronously. The auxiliary grinding plate 123 grinds the connection between the inner ring surface and the inner bottom wall of the tank 10, so that the inner wall of the tank 10 is fully ground.

[0044] See Figure 6 and Figure 7 A brush 18 is installed on the upper end of the outer arc surface of the arc plate 121. The brush 18 is evenly arranged along the arc direction of the arc plate 121. The brush 18 can move synchronously with the arc plate 121. The function of the brush 18 is to clean the polished part of the inner wall of the tank 10 to prevent the removed impurities from re-attaching to the inner ring surface of the tank 10.

[0045] See Figure 6 , Figure 8 and Figure 9 The upper end of the side block 105 is provided with a vertical circular hole. The upper surface of the square electric slider 104 is equipped with an extension fixing plate 14 around its perimeter. The upper surface of the extension fixing plate 14 is provided with a circular through hole. The circular through holes are arranged at equal intervals along the length of the extension fixing plate 14. The vertical circular hole and the corresponding circular through hole are connected by a shaft 15 through a threaded connection. The installation position of the shaft 15 is adjusted by manually removing and installing the shaft 15. As the installation position of the shaft 15 changes, the diameter of the circular structure formed by the arc-shaped grinding plate 122 changes synchronously. Based on this, the cleaning part 12 can be used for internal cleaning of tanks 10 with different inner diameters within a certain range. The effective utilization rate of the cleaning part 12 and its connected structure as a whole is improved.

[0046] See Figure 6 , Figure 8 and Figure 9An L-shaped plate 16 is arranged above the arc-shaped electric slider 106. The horizontal section of the L-shaped plate 16 is rotatably mounted on the upper end of the side block 105 via a pin. The extension fixing plate 14 is located between the vertical frame 102 and the L-shaped plate 16. The lower end face of the vertical section of the L-shaped plate 16 is connected to the upper end face of the rectangular block 120 via a magnetic layer. Before rotating the rectangular block 120, the L-shaped plate 16 is manually lifted upwards, and the L-shaped plate 16 rotates around the pin it is connected to until the L-shaped plate 16 no longer obstructs the rotation of the rectangular block 120. Then, the rectangular block 120 is manually rotated, and the arc-shaped plate 121 drives the auxiliary grinding plate 123 to move synchronously. After the arc-shaped plate 121 is rotated 180 degrees, the auxiliary grinding plate 123 faces downwards. Then, the L-shaped plate 16 is manually rotated back to its original state. The L-shaped plate 16 can play an additional role in stabilizing the position of the arc-shaped plate 121, preventing the arc-shaped plate 121 from deflecting after being rotated and affecting the auxiliary grinding work.

[0047] See Figure 10 The connecting shaft 107 and the arc-shaped electric slider 106 are connected to the side block 105 by a threaded connection. The threads at both ends of the connecting shaft 107 are in opposite directions. With the threads at both ends of the connecting shaft 107 in opposite directions, the connecting shaft 107 and the arc-shaped electric slider 106 are kept in a tight connection during the manual rotation of the rectangular block 120. By rotating the connecting shaft 107 to disengage it from the arc-shaped electric slider 106, the cleaning part 12 can be completely removed, which facilitates the specific inspection or cleaning of the cleaning part 12.

[0048] See Figure 8 and Figure 9 The auxiliary grinding plate 123 is equipped with an overlapping plate 17 at one end near the side block 105. The end of the overlapping plate 17 away from the auxiliary grinding plate 123 is connected to the upper end of the rectangular block 120 by connecting bolts. When the grinding end of the auxiliary grinding plate 123 is worn to a large degree, the grinding end of the auxiliary grinding plate 123 cannot contact the inner wall of the tank 10, and grinding cannot be carried out. At this time, the connecting bolts can be manually removed to replace the entire auxiliary grinding plate 123 and overlapping plate 17.

[0049] See Figure 1 and Figure 11The suction unit 13 includes a vacuum cleaner 130, a suction pipe 131, a main suction plate 132, and side suction plates 133. The upper end of the vacuum cleaner 130 is connected to the suction pipe 131, which is assembled from two sections of rigid pipe and flexible pipe of equal length. The lower end of the rigid pipe section of the suction pipe 131 is fitted with the main suction plate 132, which has a square structure. Side suction plates 133 are provided on all four sides of the main suction plate 132. The upper end of the side suction plates 133 is connected to the suction pipe 131 by a side pipe. The end of the side suction plate 133 facing away from the main suction plate 132 and the lower end of the main suction plate 132 are both open structures. After polishing and cleaning, the electric... The push rod is removed from the tank 10, and the cleaning section 12 and the vertical frame 102 are completely separated from the tank 10. Then, by manually holding the rigid section of the suction pipe 131, the main suction plate 132 and the side suction plate 133 are suspended inside the tank 10, and the main suction plate 132 and the side suction plate 133 move downward at a relatively uniform speed. At the same time, the vacuum cleaner 130 works. The side suction plate 133 is mainly used to remove the impurities removed from the inner ring surface of the tank 10, and the main suction plate 132 is mainly used to remove the impurities removed from the inner bottom wall of the tank 10. This multi-directional suction can speed up the removal of impurities and also prevent impurities from being left in the tank 10 again.

[0050] See Figure 11 , Figure 12 and Figure 13 The side suction plate 133 is rotatably connected to a pin at one end near the main suction plate 132. Both ends of the pin connected to the side suction plate 133 are connected to the main suction plate 132 via lugs. The side suction plate 133 is placed between two L-shaped hanging plates 134, with the lower end face of the side suction plate 133 contacting the upper end face of the horizontal section of the hanging plate 134. A T-shaped plate 135 connects the upper ends of the hanging plates 134 on the same side. A vertical electric slider 136 is installed at the end of the T-shaped plate 135 away from the hanging plate 134. The vertical electric slider 136 is installed on the vertical side end of the sleeve block 137. The sleeve block 137 is fitted onto the rigid section of the suction pipe 131. Located above the side pipe, the side suction plate 133 and the main suction plate 132 are moved downward synchronously inside the tank 10 by manual operation. When the side suction plate 133 approaches the bottom wall of the tank 10, the T-shaped plate 135 is driven downward by the vertical electric slider 136. The T-shaped plate 135 drives the hanging plate 134 to move synchronously. Under the action of gravity, the side suction plate 133 rotates downward around the pin shaft it is connected to, but the side suction plate 133 always rests on the horizontal section of the hanging plate 134. The side suction plate 133 in the inclined state can suck up the impurities accumulated at the edge of the bottom wall of the tank 10, and the suction range of the suction unit is further expanded, avoiding the occurrence of suction dead corners.

[0051] See Figure 12 and Figure 13An embedded plate 138 is installed inside the lower end of the main suction plate 132. A ventilation groove is provided at the lower end of the embedded plate 138. The upper ends of the ventilation grooves at the left and right ends of the embedded plate 138 are inclined toward the center of the embedded plate 138. The advantage of designing the ventilation groove as an inclined structure is that it expands the suction range of the main suction plate 132 and shortens the time required for impurities to be completely removed.
