Description

Technical Field

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

[0002] Pesticide suspension is an important pesticide formulation widely used in agricultural production. It forms a stable suspension system by evenly dissolving and separating solid pesticide particles in a liquid medium. It has the advantages of easy use, long-lasting efficacy, and low environmental pollution. However, traditional pesticide suspension production equipment has many problems in practical applications, which restricts the improvement of production efficiency and product quality.

[0003] First, due to the high hardness of pesticide particles, it is difficult for ordinary crushing equipment to fully refine them, resulting in uneven distribution of particle size in the suspension, affecting the efficacy of the drug. In addition, during the dissolution and separation process of liquid and powder, particles that are difficult to dissolve and separate will always be deposited in the solution, prone to eddy currents and sedimentation, and will also adhere to the inner cavity of the equipment, causing the equipment to need to be frequently shut down for cleaning. In addition, the undissolved separated particles remaining in the solution will cause the suspension to be unstable, and stratification or precipitation will easily occur during storage. Secondly, the grinding pressure of traditional grinding equipment is fixed and cannot be dynamically adjusted according to the hardness of the material, resulting in severe equipment wear and high maintenance costs.

[0014] The present invention provides a pesticide suspension production device, which has the following beneficial effects: First, the device adopts a pear-shaped tank structure, combined with the dynamic linkage design of the upper and lower grinding bodies, to achieve efficient grinding and uniform mixing of materials. The narrowing structure in the middle of the pear-shaped tank enhances the extrusion and circulation of materials between the upper and lower grinding bodies, avoiding the problem of material sedimentation at the bottom. At the same time, the upper and lower grinding bodies are linked to rotate through the locking lifting mechanism, and the third motor drives the card wheel to drive the lower grinding body to rotate as a whole, forming a dynamic and static grinding mode, which greatly improves the grinding shear force and material uniformity. This design not only improves the grinding efficiency, but also ensures the particle fineness of the pesticide suspension, meeting the needs of high-quality production.

[0015] Secondly, the device realizes a continuous and automated production process from feeding, crushing, grinding to discharging through the coordinated work of the crushing and supplying composite mechanism, the suction and flushing composite mechanism and the slag discharge pipe. The bud-shaped six-blade single-edge structure of the crushing and supplying composite mechanism generates a vortex airflow while crushing the material, assisting the dissolution and separation of the powder, and pushes the liquid downward through the spiral blades of the first water wheel, forming a negative pressure suction effect to ensure continuous material transportation. The second water wheel of the suction and flushing composite mechanism draws the ground suspension into the water pump through centrifugal force, and then discharges it through the injection pipe in the form of a high-pressure jet (to prevent the liquid outlet pipe from being blocked). It also has the functions of discharging, centrifugal separation and cleaning. Particles that are difficult to dissolve and separate will settle at the bottom. The detachable design of the slag discharge pipe further simplifies the equipment maintenance process, reduces downtime, and improves the efficiency of slag discharge and separation.

[0016] In addition, the grinding disc is connected to the cross through the sliding connection of the plug block, combined with the buffering effect of the spring, to achieve automatic adjustment of the grinding pressure, avoiding equipment wear caused by hard contact. In Example 2, the magnetic repulsion design of the electromagnet and the magnetic retaining ring further optimizes the dynamic adjustment of the grinding gap, and can adapt to the processing requirements of materials of different hardness by adjusting the current. At the same time, the brush at the lower end of the buffer rod automatically cleans the residue at the connection between the support frame and the liquid outlet pipe during the floating process of the grinding disc to prevent blockage, significantly reducing the frequency of equipment maintenance and ensuring continuous and efficient production.

[0017] Finally, the device monitors the composition ratio of the suspension concentrate in real time through the component detection probe, and feeds the data back to the control system, realizing intelligent regulation of the production process. This design not only improves the stability of product quality, but also reduces the need for manual intervention, providing reliable technical support for the large-scale production of pesticide suspension concentrates.

[0018] In summary, the present invention realizes the high efficiency, automation and intelligence of pesticide suspension production through structural innovation and functional integration, and has significant technical advantages and application value. After testing, the grinding efficiency of the device is improved by 40% compared with traditional equipment, the uniformity of particle size distribution (D90 value) is reduced from 50μm of traditional equipment to 20μm, and the energy consumption is reduced by 25%.

Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment 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.

Its pear-shaped design can enhance the extrusion and circulation of materials between the upper grinding body 5 and the lower grinding body 6 through the narrowing structure in the middle (similar to an hourglass), thereby avoiding the deposition of materials at the bottom. The upper grinding body 5 and the lower grinding body 6 are linked by a locking lifting mechanism 9. When the third motor 10 drives a single locking lifting mechanism 9 to rotate, the gear meshing (gear ring 602) drives the remaining locking lifting mechanisms 9 to rotate synchronously, thereby realizing the overall rotation of the lower grinding body 6. At the same time, the lifting auger 902 produces an upward lifting effect on the material during rotation, thereby assisting the flow of the ground material. The combination of the pear-shaped tank body and the rotating grinding body can realize dynamic grinding and static separation, thereby improving the uniformity of the pesticide suspension. A grinding disc 11 is provided at the upper end of the inner cavity of the lower grinding body 6, and the upper end of the grinding disc 11 is against the bottom of the inner cavity of the upper grinding body 5. A tetrahedral columnar plug block 1103 is vertically provided at the bottom of the grinding disc 11. The plug block 1103 is vertically slidably inserted in a cross 1104.

A spring 1106 is mounted on the buffer rod 1105. The grinding disc 11 forms a grinding surface that can float up and down through the sliding cooperation between the plug block 1103 and the cross 1104. The spring 1106 provides buffer pressure to avoid hard contact and cause equipment wear. During the grinding process, the resistance of the material to the upper grinding body 5 will be transmitted to the spring 1106 through the plug block 1103. The spring 1106 automatically adjusts the height of the grinding disc 11 according to the resistance to ensure constant grinding pressure. The magnetic repulsion design of the buffer rod 1105 and the magnetic retaining ring 1108 (mentioned later) can further dynamically adjust the grinding gap to meet the processing requirements of materials with different hardness.

[0025] Among them, a feeding pipe 101 is provided on one side of the top of the dissolution and separation grinding kettle 1, and the inner end of the feeding pipe 101 extends to the top of the crushing and supplying composite mechanism 7.

The feeding pipe 101 corresponds to the crushing and supplying composite mechanism 7 to realize the integration of "feeding-crushing-dissolution separation-transportation". The component detection probe 103 monitors the component ratio of the suspension in real time, and can be fed back to the control system to adjust the grinding parameters (such as rotation speed, grinding time). The component detection data can be used for automated production to ensure the quality stability of the pesticide suspension.

[0026] Among them, the upper end of the upper grinding body 5 is a conical grinding cover 501, the upper end of the grinding cover 501 is a liquid inlet pipe 502, the lower end of the liquid inlet pipe 502 extends to the bottom of the upper grinding body 5, and the junction between the lower end of the liquid inlet pipe 502 and the upper grinding body 5 is a conical expansion structure that is narrow at the top and wide at the bottom, and the side wall of the expansion structure is annularly distributed with arc-shaped drainage grooves 5021. The conical expansion structure plus the drainage grooves 5021 can accelerate the diffusion of liquid when it enters the upper grinding body 5 from the liquid inlet pipe 502, avoiding the generation of vortexes; the spiral first water wheel 704 (see below) cooperates with the drainage grooves 5021 to form a downward spiral liquid flow, thereby enhancing the material dissolution, separation and transportation efficiency. This design solves the problem of uneven mixing of liquid and powder in traditional devices.

[0027] Among them, the lower end of the lower grinding body 6 is a guide cover 601 which is wide at the top and narrow at the bottom. The lower end of the guide cover 601 is a liquid outlet pipe 603. A gap is left between the upper inner cavity of the lower grinding body 6 and the edge of the grinding disc 11. The ground suspension mixture flows through the guide cover 601 cavity through the gap and is discharged downward from the liquid outlet pipe 603. A gear ring 602 is fixedly provided at the upper end of the outer wall of the lower grinding body 6 at a position corresponding to the locking lifting mechanism 9. The outer ring wall of the gear ring 602 is a tooth groove. The gear ring 602 is meshed with the ring teeth 9011 of the locking lifting mechanism 9 to transmit the power of the third motor 10 to the lower grinding body 6, thereby realizing the dynamic and static rotation of the upper grinding body 5 and the lower grinding body 6, and greatly improving the grinding shear force.

The side wall of the wheel frame 703 is provided with a strip opening for liquid to pass through. The first water wheel 704 rotates to push the solution downward into the liquid inlet pipe 502. The bud-shaped six-blade single-edge structure forms a vortex airflow when rotating, which assists in the dissolution and separation of powders; the single-edge design reduces blade resistance and reduces energy consumption. The spiral blades of the first water wheel 704 push the liquid downward to form a negative pressure, and the crushed material is sucked into the liquid inlet pipe 502 to achieve continuous feeding.

[0029] The suction and flushing composite mechanism 8 includes a second motor 801, a water pumping cylinder 802, a jet pipe 803 and a second water wheel 804.

At least six jet pipes 803 are distributed in an annular manner on the water pumping cylinder 802, which synchronously follow the rotation of the water pumping cylinder 802 to pump the liquid out. The liquid in the liquid pipe 603 is discharged, and when the second water wheel 804 rotates at a high speed, the liquid is drawn from the guide cover 601 into the pumping cylinder 802 by centrifugal force, and then discharged through the injection pipe 803 in the form of a high-pressure jet, which has the functions of discharging, cleaning and upward reflux circulation, and prevents the liquid outlet pipe 603 from being blocked, so that the discharged liquid can help propel it to reflux upward along the inner wall of the dissolution and separation grinding kettle 1 for cyclic grinding. The injection pipe 803 rotates with the pumping cylinder 802, and can circumferentially flush the inner wall of the dissolution and separation grinding kettle 1 around the slag discharge pipe 4, further reducing the residual sediment.

[0030] Among them, the middle part of the slag discharge pipe 4 is a through hollow structure, and a hexagonal nut 401 that can be rotated by a tool is provided at the lower end of the slag discharge pipe 4. An external thread 402 is provided on the pipe wall of the slag discharge pipe 4, which is screwed to the bottom of the dissolution and separation grinding kettle 1.

[0032] Embodiment 2: Based on Embodiment 1, Figure 7 , Fig. 9 and Fig.10A diverter cone 1101 is provided in the middle of the upper end of the grinding disc 11. The grinding disc 11 around the diverter cone 1101 is annularly distributed with arc-shaped grinding strips 1102 to the edge of the grinding disc 11. A magnetic blocking ring 1108 is also slidably mounted on the buffer rod 1105 above the support frame 1107. The lower end of the spring 1106 abuts against the magnetic blocking ring 1108, and the upper end of the spring 1106 abuts against the plug 1103. An electromagnet is embedded in the support frame 1107 at a position corresponding to the magnetic blocking ring 1108. The magnetism of the electromagnet is the same as that of the magnetic blocking ring 1108 when the electromagnet is energized. The magnetic force of the electromagnet is adjusted by changing the current. A brush 110 is annularly distributed on the part of the buffer rod 1105 near the lower end. 9 Clean and clear the connection between the support frame 1107 and the liquid outlet pipe 603. The diverter cone 1101 will evenly dissolve and separate the material to the grinding strip 1102 area. The arc-shaped grinding strip 1102 increases the material contact path. The magnetic repulsion between the magnetic retaining ring 1108 and the electromagnet can dynamically adjust the pressure of the grinding disc 11 by adjusting the compression of the current control spring 1106. The brush 1109 on the buffer rod 1105 automatically cleans the residue at the connection between the support frame 1107 and the liquid outlet pipe 603 when moving up and down to prevent blockage and achieve self-cleaning. When processing high-hardness materials, the electromagnet current is adjusted to 5A, the magnetic repulsion increases the compression of the spring 1106 by 20%, and the grinding pressure is increased to 2MPa.

[0033] The working principle of this embodiment: The granular material enters the dissolution and separation grinding kettle 1 through the feeding pipe 101, and is first crushed by the crushing knife 702 of the crushing supply composite mechanism 7. The crushing knife 702 adopts a bud-shaped six-blade single-blade structure. When rotating at high speed, it cuts the material through the single blade and generates a vortex airflow to assist the dissolution and separation of the powder. The crushed material falls into the liquid inlet pipe 502, and under the push of the spiral blades of the first water wheel 704, a downward spiral liquid flow is formed. The first water wheel 704 cooperates with the drainage groove 5021 to accelerate the diffusion of the liquid, avoid the generation of vortices, and ensure that the material is evenly dissolved, separated and transported to the inner cavity of the upper grinding body 5.

[0034] After the material enters the grinding area, the upper grinding body 5 and the lower grinding body 6 are linked to each other through the locking lifting mechanism 9, and the third motor 10 drives the card wheel 901 to rotate. The card wheel 901 engages with the ring gear 602 through the ring tooth 9011, driving the lower grinding body 6 to rotate as a whole. The upper grinding body 5 and the lower grinding body 6 can form dynamic and static rotation (one dynamic and one static), which greatly improves the grinding shear force. During the grinding process, the grinding disc 11 is slidably connected to the cross 1104 through the plug block 1103, and the spring 1106 automatically adjusts the height of the grinding disc 11 according to the material resistance to maintain a constant grinding pressure. In Example 2, the magnetic repulsion design of the electromagnet and the magnetic blocking ring 1108 further optimizes the dynamic adjustment of the grinding gap. By adjusting the electromagnet current, the magnetic repulsion force can be changed, thereby controlling the compression amount of the spring 1106 to meet the processing requirements of materials with different hardness.

[0035] During the grinding process, the lifting auger 902 rotates with the card wheel 901 to lift the bottom material upward to the grinding area to avoid material sedimentation. The spiral structure of the external skeleton 903 provides a channel to guide the material to rise, while enhancing the structural strength of the lifting auger 902. In addition, the booster impeller 904 generates airflow when the card wheel 901 rotates, accelerates the powder to fall from the feeding pipe 101, and promotes liquid circulation, further improving the grinding and dissolution efficiency.

[0036] The ground suspension mixture flows into the liquid outlet pipe 603 through the guide cover 601, and the discharge and cleaning are completed by the suction and flushing composite mechanism 8. The second water wheel 804 rotates at a high speed under the drive of the second motor 801, and the liquid is sucked into the water pump 802 from the guide cover 601 by centrifugal force, and then discharged in the form of a high-pressure jet through the injection pipe 803. The injection pipe 803 rotates with the water pump 802, and the inner wall of the slag discharge pipe 4 and the bottom of the dissolution and separation grinding kettle 1 are circumferentially flushed to prevent the accumulation of residues. The slag discharge pipe 4 adopts a detachable design, and the bottom sediment can be quickly cleaned by rotating the hexagonal nut 401. The support ring 403 and the bottom of the second motor 801 are sealed to ensure that there is no leakage during slag discharge. At the same time, the hollow structure of the slag discharge pipe 4 is used to provide a heat dissipation channel for the second motor 801. In the second embodiment, the diverter cone 1101 of the grinding disc 11 evenly dissolves and separates the material to the grinding bar 1102 area, and the arc-shaped grinding bar 1102 extends the material contact path and improves the grinding fineness. At the same time, the brush 1109 at the lower end of the buffer rod 1105 moves up and down during the floating process of the grinding disc 11, automatically cleaning the residue at the connection between the support frame 1107 and the liquid outlet pipe 603 to prevent blockage. This self-cleaning design significantly reduces the maintenance frequency of the equipment and ensures continuous and efficient production.
