Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation, in particular to a solid-liquid separation device for a rhizobium agent which is easy to clean. Background Art

[0002] Microbial inoculants are biological products that utilize the metabolic activities of microorganisms and their products to improve the soil environment and increase crop yield and quality. In the production process of microbial inoculants, solid-liquid separation is a key link. Through solid-liquid separation, the microbial cells can be separated from the culture medium to obtain a pure inoculant product.

[0003] The applicant has found that after the solid-liquid operation in the traditional technology is completed, the filter residue is placed on the filter screen and needs to be manually cleaned, which is very troublesome. Therefore, the existing improved technology will design automatic cleaning, but still requires some manual auxiliary operations. For example, a solid-liquid separator for producing microbial agents announced in Application No. 202020882805.4 needs to release the right limit of the right baffle when discharging the residue, and then drive the left pressure plate through the electric cylinder to push the solid filter residue to the right again, so that the solid filter residue is discharged from the solid discharge port, realizing the function of conveniently discharging liquid and solid. Although the above scheme has been improved to a certain extent, it is still It requires manual participation, which is inconvenient when performing continuous solid-liquid operations. Secondly, some microbial agents may produce sticky substances during the production process, and these substances may form sticky filter residues during solid-liquid separation. For example, in agricultural liquid microbial agents, if there are viscous precipitates and these precipitates are not completely separated during the solid-liquid separation process, then the filter residue may be sticky. In addition, if the microbial agent contains high molecular weight substances, polysaccharides, proteins and other components, these components may also cause the filter residue to be sticky. These sticky substances may stick to the inside of the baffle during slag discharge and are not easy to fall off.

[0004] Therefore, the applicant proposed a solid-liquid separation device for Rhizobium inoculant that is easy to clean to solve the problem. Utility Model Content

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] Depend on Figure 1-Figure 9 A solid-liquid separation device for a rhizobium agent that is easy to clean is provided, comprising a device seat 1, a loading rack 11 is installed on the top of the device seat 1, the loading rack 11 is of U-shaped design and a material box is installed on the top, a discharge pipe of the material box passes through the loading rack 11, a horizontal plate is installed on one side of the loading rack 11, two electric push rods 12 are symmetrically passed through the horizontal plate, two "L"-shaped connecting seats are installed on the outer wall of the horizontal plate, the connecting seats are installed and connected to one end of the electric push rods 12, so as to improve the stability of the electric push rods 12, one end of the two electric push rods 12 located inside the loading rack 11 is connected to a squeeze plate 13 together, the squeeze plate 13 slides on both sides of the inside of the U-shaped frame 14, and one end of the U-shaped frame 14 is fixed to the side wall of the horizontal plate. , and both sides of the U-shaped frame 14 are fixedly connected to the inner wall of the loading rack 11, the top of the device seat 1 is movably installed with a base 2 through a driving assembly, and the top of the base 2 is installed with a second-layer plate 21 through a support rod, the top surface of the second-layer plate 21 slides in contact with the extrusion plate 13 and the bottom surface of the U-shaped frame 14, and the second-layer plate 21 is respectively installed with a filter screen 23 and a slag discharge port 22, and the filter screen 23 and the slag discharge port 22 can be moved to the inner side of the U-shaped frame 14, and a bacterial agent collection box 24 and a waste residue collection box 28 are installed on the top of the base 2, the bacterial agent collection box 24 is located below the filter screen 23 for collecting bacterial liquid, and the waste residue collection box 28 is located below the slag discharge port 22 for collecting filter residue, see Figure 7A cleaning assembly is installed on the loading rack 11 for flushing the inner side of the U-shaped frame 14 and the extrusion plate 13.

[0029] Through the above structural design, in the optimized design of slag discharge performance, when working, the material is placed in the charging box and discharged from the bottom discharge pipe, and the material falls on the filter screen 23 and is located in the interval between the extrusion plate 13 and the U-shaped frame 14. Then, the electric push rod 12 is started to make the extrusion plate 13 fit the inner sides of the U-shaped frame 14 and the surface of the filter screen 23 to move, and the bacterial agent is squeezed and filtered. The bacterial liquid penetrates the filter screen 23 and falls into the bacterial agent collection box 24 below it. As the interval gradually becomes smaller, the material is fully squeezed and filtered, and only the residue remains on the filter screen 23. Figure 6 As shown, the base 2 is then driven by the driving assembly to move together with the second layer plate 21, and the residue is blocked in the interval. When the slag discharge port 22 moves to the bottom of the interval, the slag can fall from the slag discharge port 22 and fall into the waste slag collection box 28 below, see Figure 8 , and then the base 2 is reset to carry out the next batch of bacterial agent solid-liquid separation operation.

[0030] The cleaning assembly includes two water pumping cylinders 31, which are symmetrically mounted on the inner side of the horizontal plate on the loading rack 11. A piston valve rod 32 is telescopically mounted on one side of the water pumping cylinder 31, and the piston valve rod 32 passes through a vertical plate 1 34. A vertical plate 2 33 is provided on one side of the vertical plate 1 34. The outer end rod head of the piston valve rod 32 is designed to be thinner cylindrical and fits with the vertical plate 1 34. The vertical plate 1 34 and the vertical plate 2 33 are fixed at the top edge of the second layer plate 21. The outer walls of the two water pumping cylinders 31 are connected to a square ring tube 38 through a one-way valve tube 1 37. The bottom of the square ring tube 38 is provided with arranged and distributed oblique nozzles. The outer wall of the water pumping cylinder 31 is connected to a water tank 36 through a one-way valve tube 2 35. The one-way valve tube 2 35 passes through the loading rack 11, and the two water tanks 36 are respectively placed on both sides of the loading rack 11. It should be noted that one-way valves are installed on the one-way valve tube 1 37 and the one-way valve tube 2 35. 37 can only pump water out of the pumping cylinder 31 and send it to the square annular tube 38, while the one-way valve tube 35 can only pump water out of the water tank 36 and send it into the pumping cylinder 31. Both are existing conventional design means. When the extrusion plate 13 extrude the material to the maximum position, the square annular tube 38 is located at the upper end of the interval formed by the extrusion plate 13 and the U-shaped frame 14, and the nozzle of the square annular tube 38 sprays the upper ends of the four sides of the inner part of the square interval. During solid-liquid separation, the vertical plate 2 33 and the rod head of the piston valve rod 32 have a certain distance. During the slag discharge process, when the vertical plate 2 33 and the rod head of the piston valve rod 32 are in contact, the filter screen 23 moves out of the interval formed by the extrusion plate 13 and the U-shaped frame 14 (to prevent water from entering the bacterial agent collection box 24). It should be noted that the square annular tube 38 is connected to the inner side of the loading rack 11 through the connecting block. At the same time, a drying device in the prior art can be installed in the device to quickly dry the surface of the parts after spraying.

[0031] Through the design of the cleaning component, the water pump 31 is initially filled with water. During the slag discharge process, the vertical plate 2 33 slowly moves to fit the rod head of the piston valve rod 32. At this time, the filter screen 23 moves out of the interval formed by the extrusion plate 13 and the U-shaped frame 14, and the vertical plate 1 34 slides outside the piston valve rod 32 without contact and away from the rod head. Then the vertical plate 2 33 squeezes the piston valve rod 32 to push it to move. The piston valve rod 32 slides in a sealed manner inside the water pump 31, and the water inside the water pump 31 is transported to the square ring tube 38 through the one-way valve pipe 1 37 and sprayed out, and the inner wall of the square interval formed by the extrusion plate 13 and the U-shaped frame 14 is sprayed and cleaned. When the next solid-liquid separation is reset, it is first necessary to move the base 2 together with the second layer plate 21, the filter screen 23 and the slag discharge port 22 back to the initial position through the driving component, and the extrusion plate 13 It is also reset. During this process, the water pumping cylinder 31 of the cleaning component needs to be refilled with water so that it can be used again in the next slag discharge process. In order to achieve this, after the base 2 is reset, the piston valve rod 32 is moved back by the drive of the vertical plate 1 34 (the vertical plate 1 34 will re-fit the rod head of the piston valve rod 32 and drive it to move when it is reset), and the piston valve rod 32 is also restored to its initial position inside the water pumping cylinder 31. At this time, the water in the water tank 36 is pumped into the water pumping cylinder 31 through the one-way valve tube 2 35. Due to the one-way valve design of the one-way valve tube 2 35, water can only flow in one direction, from the water tank 36 into the water pumping cylinder 31, and will not flow back. In this way, some residues can be avoided from being adsorbed on the inner side of the extrusion plate 13 and the U-shaped frame 14 during the slag discharge process, thereby improving the slag discharge efficiency, and the whole process is automated to save electricity.

[0032] The driving assembly includes a screw rod 41 rotatably installed between two support plates at the top of the device seat 1, a motor 43 driving the screw rod 41 to rotate is installed on the side wall of a support plate, the screw rod 41 is threadedly connected to the bottom protrusion of the base 2, and two rows of rollers 42 are installed at the bottom of the base 2, and the rollers 42 are in contact with the device seat 1.

[0033] Through the design of the driving component, when the driving base 2 moves, the starting motor 43 drives the screw rod 41 to rotate, and the driving is performed through the threaded connection. The base 2 can move left and right through the roller 42, which is very convenient.

[0034] An H-shaped plate 25 is installed on the top of the base 2, and the bacterial agent collection box 24 and the waste residue collection box 28 are respectively stuck on the inner sides of the two ends of the H-shaped plate 25 and aligned with the two ends of the H-shaped plate 25. Two baffles 26 are rotatably installed at both ends of the H-shaped plate 25, and the baffles 26 are fitted with the outer ends of the bacterial agent collection box 24 and the waste residue collection box 28.

[0035] By designing the H-shaped plate 25, the microbial agent collection box 24 and the waste residue collection box 28 are engaged with each other, and then the baffle plate 26 is rotated to fit with the outer ends of the microbial agent collection box 24 and the waste residue collection box 28, so that the microbial agent collection box 24 and the waste residue collection box 28 cannot move horizontally, making the microbial agent collection box 24 and the waste residue collection box 28 very stable.

[0036] A protective plate 27 is installed on the top of the second layer plate 21 through a support rod. The protective plate 27 is inserted from one side of the horizontal plate on the loading rack 11 and slides in contact with the top of the U-shaped frame 14. A circular opening corresponding to the discharge pipe of the material box is provided on the top of the protective plate 27. The protective plate 27 is located below the square ring tube 38. It should be noted that when the vertical plate 33 is in contact with the rod head of the piston valve rod 32, that is, during the slag discharge process, the protective plate 27 leaves from above the interval formed by the extrusion plate 13 and the U-shaped frame 14.

[0037] Through the design of the protective plate 27, when feeding, that is, when the material is discharged from the material box discharge pipe and the material falls from the circular mouth of the protective plate 27 onto the filter screen 23, it can play a shielding effect to prevent the bacterial liquid from splashing everywhere and also avoid splashing during extrusion filtration, forming a closed area (a small amount of material may splash out from the circular mouth, which can be ignored), and when cleaning, the square ring tube 38 starts to spray water only when the protective plate 27 leaves the area formed by the extrusion plate 13 and the U-shaped frame 14, which will not affect the cleaning process.

[0038] Working principle: First, the material is guided. As the material falls into the filter screen 23 area on the second plate 21 through the discharge pipe, the area is defined by the extrusion plate 13 and the U-shaped frame 14. Then the electric push rod 12 is started, pushing the extrusion plate 13 to slide in the U-shaped frame 14, gradually compressing the material on the filter screen 23. The bacterial liquid passes through the filter screen 23 under the action of pressure and drips into the bacterial agent collection box 24 below, while the solid residue is left on the filter screen 23. When the extrusion plate 13 reaches the maximum stroke, the solid residue is concentrated. At this time, the drive component is started, driving the base 2 and the filter screen 23 and other components to move, so that the residue is located above the slag discharge port 22, and the residue falls into the waste residue collection box 28 below. During the residue discharge process, the pumping cylinder 31 of the cleaning component is activated, and the piston valve rod 32 is pushed by the vertical plate 2 33 to slide in a sealed manner inside the pumping cylinder 31, and water is sent to the square ring tube 38 through the one-way valve tube 1 37 for spraying. The water flow flushes the inner wall of the extrusion plate 13 and the U-shaped frame 14 to remove the material residues attached thereto. After the flushing is completed, the pumping cylinder 31 re-absorbs water from the water tank 36 through the one-way valve tube 2 35 to prepare for the next operation. The base 2 and the various components installed on the top of it are reset to return to the initial position to wait for the processing of the next batch of materials. At the same time, the pumping cylinder 31 remains full of water to prepare for the next round of flushing.
