Description

Technical Field

[0001] This invention relates to the field of fertilizer production technology, and in particular to a production apparatus for selenium-containing water-soluble fertilizer. Background Technology

[0002] Water-soluble fertilizer is a highly efficient compound fertilizer that is completely soluble in water. Its nutrients exist in ionic form and can be precisely applied through irrigation systems. It features rapid absorption, high utilization rate, and environmental friendliness. Based on their physical form, water-soluble fertilizers can be divided into two categories: solid water-soluble fertilizers and liquid water-soluble fertilizers. Solid water-soluble fertilizers exist in powder, granule, or crystal form and must be dissolved in water before use; liquid water-soluble fertilizers exist directly in solution or suspension form, requiring no secondary dissolution, and are more convenient to use.

[0003] Selenium-containing liquid water-soluble fertilizer, as a functional specialty fertilizer, imparts selenium enrichment to crops and enhances the added value of agricultural products by adding selenium compounds (such as sodium selenite and selenomethionine) to traditional nutrient solutions. Its production process requires ensuring that selenium is uniformly dispersed in the liquid phase and maintains chemical stability, avoiding precipitation or stratification. To achieve this, a stirrer is used. Water, macroelements (nitrogen, phosphorus, potassium), microelements, and functional additives (such as selenium compounds) are added to the reaction tank according to the formula, and homogenization is achieved through mechanical stirring.

[0004] However, existing mixing processes have significant drawbacks:

[0005] 1. Uneven mixing problem: Conventional agitators (such as paddle and turbine agitators) are prone to creating "laminar flow zones" and "stirring dead zones" inside the tank, causing denser selenium compounds to deposit at the bottom of the tank, forming a concentration gradient.

[0006] 2. Layering phenomenon: In a static tank, the unmixed materials naturally separate into layers due to density differences. The lower layer of high-concentration selenium-rich solution is difficult to be disturbed by the upper weak stirring zone, so the stirring cycle needs to be extended.

[0007] While existing technologies attempt to improve mixing by optimizing blade angles, adding baffles, or using multi-layer agitators, they still struggle to simultaneously address the dual requirements of uniform horizontal dispersion and forced vertical convection. In particular, the low dispersion efficiency for easily sedimenting trace elements such as selenium has become a bottleneck restricting product quality.

[0008] Therefore, the present invention provides a selenium-containing water-soluble fertilizer production device, which uses the circumferential extension and retraction of the stirring blades in conjunction with the circulating pump to form a three-dimensional circulation state of horizontal push flow and vertical convection, which can better solve the problems of uneven mixing and stratification. Summary of the Invention

An elastic element is disposed in the insertion hole and connected to the end of the blade rod facing the rotating shaft.

[0013] Preferably, the blade has notches at both ends and on the side that fits the blade stem.

[0014] Preferably, the thickness of the ring rail gradually decreases from the outer edge to the inner ring.

[0015] Preferably, the lower end of the rotating shaft is provided with a crankshaft, and a collar is rotatably mounted on the crank pin of the crankshaft. Multiple handles are rotatably connected to the outer edge of the collar, and pistons are rotatably connected to the ends of the handles. The processing tank is provided with circulation cylinders corresponding to the pistons one by one. The circulation cylinders are open on the side facing the rotating shaft, and the pistons are embedded into the circulation cylinders from the openings. The end of the circulation cylinder opposite to the rotating shaft is provided with a feed port and a discharge port. One-way valve structures are provided at the connection points of the feed port, the discharge port and the circulation cylinder, respectively, for controlling the feeding and discharging of materials in the circulation cylinder. The discharge port is connected to a circulation pipe.

[0016] Preferably, the one-way valve structure includes a mounting base disposed on the back side of the circulation cylinder, a through-feed port on the back side of the circulation cylinder, a material channel on the side of the mounting base facing the circulation cylinder, one end of the material channel communicating with the feed port and the other end extending to the side wall of the mounting base and communicating with the inside of the processing tank, a stop hole is provided on the side of the mounting base facing the circulation cylinder at the material channel, a stop element is embedded in the stop hole, a driven rod passing through the mounting base is provided on the side of the stop element away from the circulation cylinder, a pry bar is rotatably mounted on the side of the mounting base away from the circulation cylinder, an elastic element is provided between the pry bar and the mounting base, straight grooves are provided at both the upper and lower ends of the pry bar, the end of the driven rod is embedded in the lower straight groove, an active rod that moves axially along the circulation cylinder is embedded in the upper straight groove of the pry bar, and the other end of the active rod abuts against an eccentric wheel disposed on a rotating shaft.

[0017] Preferably, the circulation pipe is provided with multiple branch pipes facing the axis of the processing tank, and the ports of the multiple branch pipes on each circulation pipe are spaced at different distances from the axis of the processing tank.

[0018] Preferably, the processing tank is further provided with a cylinder body, and multiple circulation cylinders are connected to the cylinder body, with the crankshaft, handle, and eccentric wheel all located inside the cylinder body.

[0019] Preferably, it also includes a stand, with a hopper at the top of the stand, a wall-breaking machine at the top of the hopper, and a discharge pipe with a valve connected to the bottom of the hopper. The bottom of the discharge pipe is connected to an auger conveyor via a rotary joint, and the end of the auger conveyor is provided with a conveying pipe that cooperates with the feed pipe of the processing tank.

[0020] Preferably, the lower end of the hopper is provided with a distribution pipe with a valve on the side of the discharge pipe. The distribution pipe is inclined downwards, and the end of the distribution pipe is connected to an auger conveyor II. The upper end of the auger conveyor II is connected to the feeding port of the wall-breaking machine.

[0021] Compared with the prior art, the present invention provides a selenium-containing water-soluble fertilizer production device, which has the following beneficial effects:

[0022] 1. The present invention features a separate design for the stirring blade and the rotating shaft. While the stirring blade rotates synchronously with the rotating shaft, it can also move radially. This achieves shearing, diffusion, and stirring of the material in the horizontal layer, while the radial pushing of the material by the guide plate realizes material convection between the inside and outside of the horizontal layer, thereby eliminating the concentration difference in the horizontal layer.

[0023] 2. In this invention, a crankshaft is also provided at the lower end of the rotating shaft. The crankshaft is connected to the handle and a piston embedded in the circulation cylinder. As the rotating shaft rotates, it drives the piston to move back and forth in the circulation cylinder, thereby forcibly spraying the liquid at the bottom layer to the upper layer, forming a vertical circulation convection, breaking down the layering barrier. In conjunction with the radially movable stirring blades, it can also reduce the stirring dead angle.

[0024] 3. In this invention, the circulation pipe connected to the outlet of the circulation cylinder is equipped with multiple diversion pipes, which can realize the mixing of materials between multiple horizontal layers. Since the ports of the multiple diversion pipes are spaced at different distances from the axis of the processing tank, mixing can be performed at multiple points between multiple horizontal layers, resulting in more uniform mixing.

[0025] 4. The present invention is equipped with a one-way valve structure and a matching drive structure, which drives the piston to move back and forth in the circulation cylinder by rotating the shaft, thereby opening the feed port and the discharge port to prevent the flow direction of feed and discharge in the circulation cylinder from being disordered and to ensure the stable convection of the upper and lower layers of liquid.

[0026] 5. In this invention, notches are provided at both ends of the blade and on the side that is in contact with the blade shaft. These notches allow for avoidance of interference, eliminating the need to shorten the blade length and ensuring the blade maintains a consistent length.

[0027] 6. This invention also includes pre-processing equipment, including a wall-breaking machine, an auger conveyor I, and an auger conveyor II. This enables pre-crushing / mixing of materials, material conveying to the processing tank, and cyclic crushing / mixing of substandard materials. It reduces the mixing pressure in the processing tank and features automatic monitoring, thus reducing labor burden.

[0028] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0053] The following will refer to the appendices in the embodiments of the present invention. Figure 1-23 The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0054] Example 1: To address the issues of stratification and unevenness during the production of liquid water-soluble fertilizers, this example provides a selenium-containing water-soluble fertilizer production device, comprising a processing tank 1. The processing tank 1 has a feed pipe and a discharge pipe with valves at its upper and lower ends, respectively. The device is characterized by a rotating shaft 3 rotatably mounted inside the processing tank 1, driven by an external drive device 2. Multiple drive discs are axially spaced on the rotating shaft 3, and multiple radially arranged rails 4 are provided on the outer edge of each drive disc. A stirring blade 6 is slidably mounted on the rail 4, and an elastic element 8 is provided between the stirring blade 6 and the rail 4. A guide plate 7 is provided at the end of the stirring blade 6 facing the rotating shaft 3. A ring rail 9, corresponding to each drive disc, is provided on the inner wall of the processing tank 1. The end of the stirring blade 6 facing away from the rotating shaft 3 abuts against the inner wall of the ring rail 9, and the inner wall of the ring rail 9 has multiple arc-shaped protrusions.

[0055] Principle details of this embodiment:

[0056] A selenium-containing water-soluble fertilizer production device includes a processing tank 1. The processing tank 1 is made of martensitic stainless steel and includes a tank body and a lid. The edges of the tank body and lid are flanged and fastened together with bolts, with a sealing gasket at the joint to prevent leakage. A feed pipe is provided on the lid for adding material into the processing tank 1. The lower end of the tank body is tapered to facilitate material accumulation and discharge; a discharge pipe is provided at the lower end of the tank body for discharging material. Valves (not shown in the attached diagram), such as electric butterfly valves, are provided at both the feed pipe and the discharge pipe to control their opening and closing.

[0057] See attached document Figure 3As shown, a geared motor is installed on the upper end of the tank cover of processing tank 1. The tank cover has a through hole for the output shaft of the geared motor to pass through, and a shaft seal is installed at the through hole. The output shaft of the geared motor is connected to a rotating shaft 3 via a flange structure, as shown in the attached diagram. Figure 4 Appendix Figure 5 As shown, multiple drive discs are axially spaced on the rotating shaft 3. The drive discs are connected to the rotating shaft 3 by screws to achieve synchronous rotation of the drive discs and the rotating shaft 3.

[0058] See attached document Figure 10 As shown, multiple rails 4 are arranged in a ring on the outer edge of the drive disk. The rails 4 are arranged radially along the drive disk. The ends of the multiple rails 4 are connected to a reinforcing ring 5 to reinforce the ends of the rails 4 and prevent the drive from shaking.

[0059] See attached document Figure 9 As shown, each rail 4 is slidably mounted with a stirring blade 6, which is a sheet-like plate structure. An elastic element 8, which is a spring, is provided between the end of the stirring blade 6 facing the rotating shaft 3 and the rail 4. The elastic element 8 provides an external thrust to the stirring blade 6, so that the stirring blade 6 always tends to move away from the rotating shaft 3.

[0060] See attached document Figure 13 As shown, the stirring blade 6 has a guide plate 7 facing the rotating shaft 3 at one end, and the guide plate 7 has an arc-shaped structure facing away from the rotating shaft 3.

[0061] See attached document Figure 4 Appendix Figure 5 As shown, ring rails 9 are bolted to the inner wall of the processing tank 1, and the number of ring rails 9 corresponds one-to-one with the number of drive discs. (See attached diagram.) Figure 7 Appendix Figure 9 As shown, the stirring blade 6 rests against the inner ring of the ring rail 9 at the end opposite to the rotating shaft 3, and the inner ring of the ring rail 9 has a ring array of multiple arc-shaped protrusions.

[0062] Based on the above technical solution:

[0063] In operation, the geared motor drives the rotating shaft 3 to rotate synchronously, which in turn drives all the drive discs to rotate synchronously. The drive discs, via the rails 4, drive all the stirring blades 6 to rotate synchronously, thus forming a traditional fan-blade type agitator structure. This agitates the water-soluble material in the tank, achieving shear diffusion of the material in the horizontal layer. While the stirring blades 6 rotate, under the action of the elastic element 8, they move along the inner wall of the ring rail 9, exhibiting a radial movement trend within the treatment tank 1. Combined with the circumferential rotation, this causes the guide plate 7 to exhibit a wave-like movement within the treatment tank 1. The wave-like movement of the guide plate 7, with its arc-shaped structure facing away from the rotating shaft 3, pushes material near the axis towards the tank wall when it moves away from the shaft; when it approaches the shaft, the arc-shaped guide plate 7 causes the compressed material to diffuse and transfer to both sides along the arc structure. This combination eliminates adhesion to the tank wall and reduces the concentration difference in the horizontal layer.

[0064] In this embodiment, a pressure regulating valve is provided on the lid of the processing tank 1 to balance the gas pressure after the materials in the processing tank 1 have been fermented and fused.

[0065] In this embodiment, the processing tank 1 is also equipped with heating equipment, such as a coiled electric heating tube, to regulate the temperature of the material fusion environment. The outer wall of the processing tank 1 is wrapped with an insulation layer for heat preservation.

[0066] In this embodiment, in order to improve the stability of the rotating shaft 3 in the treatment tank 1, multiple star-shaped support seats 10 are arranged between the multi-layer ring rails 9 in the treatment tank 1. The support seats 10 are provided with bearing seats at their axial centers, and the rotating shaft 3 passes through the inner ring of the bearing in the bearing seat, thereby supporting and reinforcing the rotating shaft 3; while the star-shaped structure does not affect the flow and leakage of the liquid.

[0067] In this embodiment, a support (not shown in the attached figure) is provided to support the processing tank 1, so that the processing tank 1 is stably suspended in the air.

[0068] Example 2, a further embodiment of this solution, refers to the appendix. Figure 13 As shown, the stirring blade 6 includes a blade rod 601, and blades 602 are fixedly installed at both ends of the blade rod 601 by screws. Both sets of blades 602 are provided with guide plates 7 at the ends facing the rotating shaft 3.

[0069] See attached document Figure 10 Appendix Figure 12As shown, the rail 4 has an opening groove along its length, within which the blade 601 is slidably mounted. The end of the opening groove facing the rotating shaft 3 has an insertion hole, into which the elastic element 8 is disposed; the reinforcing ring 5 has mounting holes corresponding to the insertion hole. One end of the blade 601 is inserted into the insertion hole and connected to the elastic element 8, while the other end of the blade 601 passes through the mounting hole and abuts against the inner ring of the ring rail 9. This constitutes the sliding mounting structure of the stirring blade 6, and the sliding mounting of the blade 601 within the rail 4 provides a wider mounting support surface for the stirring rod, making it more stable against the shear resistance encountered during stirring.

[0070] In this embodiment, refer to the appendix Figure 12 As shown, a rubber ring is provided at the inlet of the insertion hole. The rubber ring wraps around the blade 601 to prevent liquid from seeping into the insertion hole and causing inconvenience in cleaning.

[0071] In this embodiment, refer to the appendix Figure 10 As shown, a notch 38 is provided on the upper side of the opening groove on the rail rod 4, which is used for the material liquid to seep out from the opening groove. Especially in the cleaning state, the cleaning water flows out from the notch 38 and remains in the space where the opening groove and the blade rod 601 are assembled.

[0072] In Example 3, a further embodiment of this solution, since the blade 602 moves back and forth within the opening slot along with the blade rod 601, to avoid interference with the blade 602 when the blade rod 601 moves back and forth at the insertion hole and mounting hole ports, refer to the attached... Figure 12 Appendix Figure 13 As shown, notches are provided at both ends of the blade 602 and on the side that is in contact with the blade shaft 601. The notches are used to avoid interference, so that the blade 602 can maintain a certain length without having to shorten its length.

[0073] Example 4, a further embodiment of this solution, in order to prevent liquid residue on the surface of the ring rail 9, the thickness of the ring rail 9 is designed to gradually decrease from the outer edge to the inner ring, forming a sloping shoulder design, so as to promote the liquid to slide off and reduce residue.

[0074] Example 5, a further embodiment of this solution, further optimizes the mixing of the liquid mixture in this embodiment, based on achieving balanced mixing through alternating internal and external circulation of the horizontal layer: refer to Appendix Figure 4 Appendix Figure 15 Appendix Figure 16 As shown, a crankshaft 11 is provided at the lower end of the rotating shaft 3. The crankshaft 11 includes a main journal, and a flange is provided at the joint between the main journal and the rotating shaft 3, which is connected by bolts. A crank is provided at the lower end of the main journal, and a crank pin is provided at the end of the crank. A collar is rotatably mounted on the crank pin, and multiple stems 12 are rotatably mounted on the outer edge of the collar. A piston 13 is rotatably connected to the end of the stems 12.

[0075] See attached document Figure 17 As shown, the processing tank 1 is equipped with a circulation cylinder 14 corresponding to each piston 13. The circulation cylinder 14 has an opening facing the rotating shaft 3, and the piston 13 is inserted into the circulation cylinder 14 through the opening. The end of the circulation cylinder 14 opposite to the rotating shaft 3 has an inlet and an outlet. One-way valves are installed at the connection points between the inlet and outlet and the circulation cylinder 14, respectively, to control the feeding and discharging of materials within the circulation cylinder 14. (Refer to the attached diagram.) Figure 6 As shown, the discharge port is connected to a circulation pipe 15, which extends upwards. The inlet is connected to a feeding pipe 17, which extends downwards, with its lower end close to the bottom wall of the processing tank 1.

[0076] Based on the above technical solution:

[0077] When the rotating shaft 3 rotates, it causes the crankshaft 11 to deflect synchronously, thereby driving all the handles 12 to deflect synchronously and push and pull through the collar, causing multiple sets of pistons 13 to reciprocate within the circulation cylinder 14. When the piston 13 moves towards the crank side within the circulation cylinder 14, the one-way valve structure of the inlet opens and the one-way valve structure of the outlet closes, and the liquid in the treatment tank 1 is drawn into the circulation cylinder 14 from the injection pipe 17; when the piston 13 moves away from the crank side within the circulation cylinder 14, the one-way valve structure of the inlet closes and the one-way valve structure of the outlet opens, and the liquid in the circulation cylinder 14 is squeezed into the circulation pipe 15 from the outlet, and then sprayed out along the upper port of the circulation pipe 15, forcibly transporting the high-concentration liquid that has settled in the lower layer to the upper layer, forming a vertical jet, creating a circulating convection between the upper and lower layers, and breaking down the stratification barrier.

[0078] In this embodiment, the circulation pipe 15 is provided with multiple branch pipes 16 facing the axis of the processing tank 1, which can realize the mixing of materials between multiple horizontal layers. The ports of the multiple branch pipes 16 on each circulation pipe 15 are spaced differently from the axis of the processing tank 1, allowing mixing at multiple points between multiple horizontal layers, resulting in more uniform mixing.

[0079] Example 6, a further embodiment of this solution, provides two specific one-way valve structures:

[0080] First method: Refer to the appendix Figure 19 As shown, both sets of one-way valve structures are equipped with mounting seats 18, which are fastened to the back side of the circulation cylinder 14 by screws. (Refer to the attached diagram.) Figure 22 As shown, the back side of the circulation cylinder 14 is provided with two sets of through conveying ports 20, which serve as material conveying channels for two sets of one-way valve structures. The mounting base 18 is provided with two sets of material channels 19 on the side facing the circulation cylinder 14, which correspond to the two conveying ports 20 respectively.

[0081] See attached document Figure 20 Appendix Figure 21As shown, both material channels 19 are shaped like the number 7. The horizontal end of material channel 19 is connected to the conveying port 20, and the vertical end of material channel 19 extends to the side wall of the mounting base 18. Material channel 19 connects with the injection pipe 17 and communicates with the inside of the processing tank 1. The mounting base 18 facing the circulation cylinder 14 has a stop hole at the material channel 19, and a stop element 21 is embedded in the stop hole. The stop element 21 is provided with a driven rod 22 that passes through the mounting base 18 on the side away from the circulation cylinder 14. A pry bar 23 is rotatably mounted on the side of the mounting base 18 away from the circulation cylinder 14. An elastic element two, which is a torsion spring or a disc spring, is provided between the pry bar 23 and the mounting base 18. Under the action of the elastic element two, the upper end of the pry bar 23 always tends to rotate towards the shaft 3. A rubber buckle cover can be installed on the mounting base 18 to isolate the elastic element two from the liquid. Both the upper and lower ends of the pry bar 23 are provided with straight grooves. The end of the driven rod 22 is provided with an insert rod, which is embedded in the lower straight groove. A second insert rod is embedded in the straight groove on the upper side of the pry bar 23. The second insert rod is connected to an active rod 24 that moves axially along the circulation cylinder 14. The other ends of the active rods 24 of the two sets of one-way valve structures abut against eccentric wheels 25 set on the rotating shaft 3. The two eccentric wheels 25 are axially spaced on the rotating shaft 3. One of the two eccentric wheels 25 has a groove and the other has a protrusion. The groove and the protrusion are located at the same position and are offset from the crank pin of the crankshaft 11.

[0082] The active rod 24 of the one-way valve structure corresponding to the discharge port abuts against the eccentric wheel 25 with a groove. When the active rod 24 abuts against the circular surface of the eccentric wheel 25, the active rod 24 deflects against the pry bar 23, and the pry bar 23 pushes the stop member 21 away from the corresponding material channel 19 against the driven rod 22, so that the discharge channel of the circulation cylinder 14 is in the open state. When the active rod 24 abuts against the groove of the eccentric wheel 25, the corresponding pry bar 23 deflects in the opposite direction under the action of the elastic member 2, thereby pulling the driven member and closing the corresponding material channel 19, so that the discharge channel of the circulation cylinder 14 is in the closed state.

[0083] The active rod 24 of the one-way valve structure corresponding to the feed inlet abuts against the eccentric wheel 25 with a protrusion. When the active rod 24 abuts against the circular surface of the eccentric wheel 25, the shut-off element 21 blocks the corresponding material channel 19, so that the feed channel of the circulation cylinder 14 is in a closed state. When the active rod 24 abuts against the protrusion of the eccentric wheel 25, the active rod 24 will deflect against the corresponding pry bar 23, and the lower end of the pry bar 23 will abut against the driven rod 22, pushing the corresponding shut-off element 21 away from the corresponding material channel 19, so that the material channel 19 is opened, and the feed channel of the circulation cylinder 14 is in an open state.

[0084] Thus, during use, the rotating shaft 3 drives the crankshaft 11 to rotate, thereby causing the piston 13 to reciprocate within the circulation cylinder 14. Simultaneously, the two sets of eccentric wheels 25 alternately abut against the two sets of drive rods 24, causing the corresponding two sets of pry bars 23 to deflect in opposite directions. This ensures that the feed channel and discharge channel of the circulation cylinder 14 are always in an open and closed state, thus forming a single-opening and closing double one-way valve structure. The circulation cylinder 14, in conjunction with the two sets of one-way valves, can realize the pumping in and extrusion of liquid material.

[0085] The second method: refer to the appendix Figure 23 As shown, the two sets of one-way valve structures share a single valve seat 26, which is fastened to the back side of the circulation cylinder 14 with screws. The valve seat 26 has two sets of L-shaped valve holes 27, corresponding to the inlet and outlet respectively. The back side of the circulation cylinder 14 has conical holes 28 that correspond one-to-one with the valve holes 27. The two conical holes 28 have opposite flaring directions: one faces inwards towards the circulation cylinder 14, corresponding to the inlet; the other faces outwards towards the circulation cylinder 14, corresponding to the outlet. The two conical holes 28 are identical to the horizontal ports of the two valve holes 27, and the vertical ports extend through the valve seat 26. Conical plugs 29 are embedded in both conical holes. Each conical plug 29 has a connecting rod 30 on the side facing away from the circulation cylinder 14, extending from the horizontal portion of the valve hole 27 and penetrating the valve seat 26. Two retainers are fastened to the side of the valve seat 26 facing away from the circulation cylinder 14 with screws, and the ends of the connecting rods 30 extend into the corresponding retainers. An elastic element 31, which is a spring, is provided between the two sets of connecting rods 30 and the corresponding buckle covers. The elastic element 31 causes the conical plug 29 to tend to block the corresponding conical hole.

[0086] When piston 13 moves toward crankshaft 11, the internal air pressure of circulating cylinder 14 decreases, causing the flared end to face the conical plug 29 (attached) inside circulating cylinder 14. Figure 23 The lower conical plug 29 is drawn into the circulation cylinder 14, and the corresponding valve hole 27 opens, thus opening the feed channel of the circulation cylinder 14 and allowing the liquid to enter the circulation cylinder 14. Meanwhile, the other conical plug 29 is more firmly pressed against the corresponding conical hole under the suction force, so that the outlet of the circulation cylinder 14 is in a closed state.

[0087] When piston 13 moves away from crankshaft 11, piston 13 compresses the liquid in circulation cylinder 14, causing the conical plug 29 (attached) to expand away from circulation cylinder 14. Figure 23 The lower conical plug 29 pushes away from the corresponding conical hole 28, opening the corresponding valve hole 27 and thus opening the discharge channel of the circulation cylinder 14. The liquid material can then enter the circulation pipe 15 through the valve hole 27, thereby spraying the liquid material in the circulation cylinder 14 to the upper layer. Meanwhile, the other conical plug 29, under the action of extrusion pressure, more firmly engages with the corresponding conical hole, keeping the feed inlet of the circulation cylinder 14 closed.

[0088] In Example 7, a further embodiment of this solution, in order to reduce the residue of the liquid in the workpiece, especially in the transmission components, transmission parts, and channel parts, the treatment tank 1 is also provided with a cylinder body 41. Multiple circulation cylinders 14 are all fastened to the cylinder body 41 by screws. The crankshaft 11, the handle 12, and the eccentric wheel 25 are all located inside the cylinder body 41, so that the entire circulation system is in a closed state, which can reduce the contact between the transmission components and the liquid, and also reduce the residue on the corresponding parts.

[0089] The cylinder body 41 is provided with guide sleeves that correspond one-to-one with the drive rod 24. The drive rod 24 passes through the guide sleeve and enters the cylinder body 41. The guide sleeves position and install the drive rod 24. The drive sleeve is provided with a rubber sleeve for sealing.

[0090] In Example 8, a further embodiment of this solution, a support frame 32 is also provided. A hopper 34 is provided at the upper end of the support frame 32, and a wall-breaking machine 33, which is a shear-type pulverizer, is provided at the upper end of the hopper 34. A discharge pipe with a valve is connected to the lower end of the hopper 34, and an auger conveyor 36 is connected to the lower end of the discharge pipe via a rotating joint 35. The end of the auger conveyor 36 is provided with a conveying pipe that cooperates with the feed pipe of the processing tank 1.

[0091] During use, the blender 33 can be used for auxiliary crushing to break down materials that do not meet the required particle size into the desired size. Materials that meet the requirements can be agitated by the blender 33 to premix the materials.

[0092] Materials meeting the particle size requirements are fed into the processing tank 1 via an auger conveyor 36 for processing. The auger conveyor 36 is connected to the hopper 34 via a rotary joint 35, enabling it to self-rotate. This allows the auger conveyor 36 to be deflected and moved away when the tank lid of the processing tank 1 needs to be opened, without interference.

[0093] In this embodiment, the lower end of the hopper 34 is provided with a distribution pipe with a valve on the side of the discharge pipe. The distribution pipe is inclined downwards, and the end of the distribution pipe is connected to an auger conveyor 37. The upper end of the auger conveyor 37 is connected to the feed port of the blender 33. The connection can be through insertion from the side wall or suspended at the port (the attached figure shows the suspended port). Circulating crushing is possible: when the valve of the hopper 34 is closed, the crushed material accumulates in the hopper 34, and then leaks through the distribution pipe into the auger conveyor 37, and is then reinjected into the blender 33 for crushing. This is suitable for materials that have not undergone pre-crushing treatment.

[0094] In this embodiment, a clamp is installed between the conveying pipe of the auger conveyor 36 and the feeding pipe of the processing tank 1, providing a tight connection. The clamp can be removed when relocation is required.

[0095] In this embodiment, a bracket is also provided, on which an arc-shaped support rail is mounted. The support rail is coaxial with the rotation axis of the auger conveyor 36. An auxiliary support is provided on the auger conveyor 36, and a guide wheel is provided at the lower end of the support. The guide wheel rests on the support rail, thereby providing auxiliary support for the auger conveyor 36.

[0096] In this embodiment, a lifting frame 39 is also provided, on which a lifting motor is mounted. The output shaft of the lifting motor is connected to a lead screw, and a lead screw nut is threaded onto the lead screw. The lead screw nut is connected to a slide block, which is vertically slidably mounted on the lifting frame. An extension frame 40 is provided on the slide block, and the extension frame 40 is connected to the lid of the processing tank 1 to control the opening and closing of the lid of the processing tank 1. The output shaft of the geared motor can be provided with a rectangular connecting shaft, and the upper end of the rotating shaft 3 is provided with a rectangular hole. Power is transmitted through the insertion of the connecting shaft into the rectangular hole, without affecting the opening of the lid of the processing tank 1.
