Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically to a reaction device for preparing anti-clogging material for water-soluble fertilizer anti-caking agents. Background Technology

[0002] In the process of the vigorous development of modern agriculture, water-soluble fertilizers have been widely used in agricultural production due to their significant advantages such as easy absorption and rapid effect. As a key additive to ensure the quality of water-soluble fertilizer products and prevent caking, the preparation process and production efficiency of water-soluble fertilizer anti-caking agents have attracted much attention. Among them, the reaction device is the core equipment for the production of water-soluble fertilizer anti-caking agents, and the performance of its discharge stage directly affects the smoothness of the entire production process and the quality of the products.

[0003] Currently, most reaction devices used for preparing water-soluble fertilizer anti-caking agents on the market adopt a traditional discharge structure design. This structure has many drawbacks in actual production. Due to the complex composition of raw materials and products of water-soluble fertilizer anti-caking agents, some highly viscous materials tend to adhere to the inner wall of the discharge channel during discharge. Over time, these materials gradually accumulate and block the channel, leading to poor discharge or even complete blockage. Once a blockage occurs, production personnel have to stop production and disassemble and clean the device, which not only consumes a lot of manpower and time but also seriously reduces production efficiency and disrupts normal production plans. In addition, traditional reaction devices are difficult to effectively filter and separate materials during the discharge process. Some unreacted impurities and clumps can easily mix into the product. The presence of these impurities not only affects the purity and performance of the water-soluble fertilizer anti-caking agent but may also have adverse effects on crop growth during subsequent use of the water-soluble fertilizer, damaging the product's market reputation.

[0004] Therefore, in view of the above-mentioned problems in the discharge stage of the existing reaction device for preparing water-soluble fertilizer anti-caking agent, it is urgent to develop a new type of anti-clogging reaction device to achieve efficient, stable and precise discharge, ensure the product quality of water-soluble fertilizer anti-caking agent and reduce production costs. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging reaction device for the preparation of water-soluble fertilizer anti-caking agents, so as to solve the problems mentioned in the background art, such as the easy blockage of the discharge channel due to material adhesion and accumulation, resulting in low production efficiency, and the difficulty in effectively filtering and separating materials, causing impurities to be mixed in and affecting product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reaction device for preparing anti-clogging material for water-soluble fertilizer anti-caking agent, comprising a vessel body, a discharge barrel fixedly installed at the lower end of the vessel body, a sliding discharge pipe installed inside the discharge barrel, a temporary storage chamber opened inside the upper end of the discharge pipe, and a filter hole opened on the outer surface of the upper end of the discharge pipe, a pressure relief hole opened at the lower end of the discharge barrel, a piston chamber opened inside the lower end of the discharge pipe, one end of a piston rod installed inside the piston chamber, and the other end of the piston rod penetrating the lower surface of the discharge pipe, a toothed block fixedly installed on the outer surface of the middle section of the discharge pipe, a rotating gear installed inside the discharge barrel side surface on the side of the discharge pipe with the toothed block, and a motor fixedly installed inside the discharge barrel on the side of the discharge pipe with the toothed block;

[0007] The lower end of the discharge hopper has a sedimentation chamber, and a partition plate is fixedly installed on the bottom surface of the sedimentation chamber. An overflow plate is fixedly connected to the upper end of the partition plate. A splash guard is fixedly installed on the top surface of the sedimentation chamber. A one-way valve is fixedly installed on the outer surface of the lower end of the discharge hopper.

[0008] Preferably, the discharge pipe and the discharge barrel are connected by sliding friction, and the upper end of the discharge pipe passes through the upper end of the discharge barrel and is located inside the lower end of the reactor body.

[0009] By adopting the above technical solution, the discharge pipe can slide up and down inside the discharge bucket. With the meshing transmission of the toothed block and gear, the material attached to the outer wall of the discharge pipe is scraped off and vibrated, preventing the material from accumulating and blocking the discharge channel.

[0010] Preferably, the lower end of the temporary storage chamber is connected to the upper end of the piston chamber, the upper end of the piston rod is slidably frictionally connected to the piston chamber, and a return spring is connected between the upper end of the piston rod and the piston chamber. The lower end of the piston rod is slidably connected to the discharge pipe with clearance fit, and the lower end of the piston rod is fixedly connected to the discharge bucket.

[0011] Using the above technical solution, when the discharge pipe slides up and down, the piston rod moves relative to the piston chamber. The volume change of the piston chamber is achieved by the elastic force of the return spring, thereby completing the suction and discharge of materials. At the same time, the pressure when discharging materials can clear the blockage in the filter holes and ensure smooth discharge.

[0012] Preferably, the gear has a missing tooth design, and the gear is connected to the discharge pipe through a tooth block, and the gear shaft is fixedly connected to the output shaft of the motor.

[0013] Using the above technical solution, the toothed gear can periodically mesh with the toothed block when it rotates, driving the discharge pipe to make reciprocating sliding motion in the discharge bucket. Through sliding vibration and mechanical scraping, the material accumulation on the outer wall of the discharge pipe and near the filter hole is effectively removed, enhancing the anti-clogging effect.

[0014] Preferably, the partition plate and the splash guard are both arc-shaped, and the partition plate, the splash guard and the discharge pipe are concentrically arranged.

[0015] Using the above technical solution, the arc-shaped partition plate and splash guard can guide the material to flow smoothly and avoid splashing caused by material impact. The concentric arrangement ensures that the material is evenly distributed around the discharge pipe. Together with the sedimentation chamber, it can achieve efficient sedimentation of impurities and static separation of materials.

[0016] Preferably, the overflow plate has a flared design with a larger top and a smaller bottom, and a gap is left between the outer surface of the upper end of the overflow plate and the inner surface of the sedimentation chamber.

[0017] Using the above technical solution, the overflow plate with the flared mouth design can guide the upper clear liquid to overflow smoothly along the gap, realizing solid-liquid separation. The existence of the gap prevents the clear liquid from mixing with the lower impurities, ensuring the purity of the discharged material. At the same time, the flared mouth structure can slow down the liquid flow rate and reduce the possibility of impurities being carried out with the clear liquid.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the anti-clogging reaction device for preparing water-soluble fertilizer anti-caking agent:

[0019] 1. The material enters the temporary storage chamber through the filter holes on the outer surface of the upper end of the discharge pipe, which can effectively intercept larger particles of impurities and prevent them from clogging the discharge channel. At the same time, the discharge pipe and the discharge barrel are connected by sliding friction, and a rotating gear is installed inside the discharge barrel side surface on the side of the discharge pipe with toothed blocks. The gear is connected to the discharge pipe through the toothed blocks. The motor drives the gear to rotate, which allows the discharge pipe to slide up and down in the discharge barrel. This sliding structure helps to shake off and scrape off large particles of material attached to the outer wall of the discharge pipe, further preventing blockage.

[0020] 2. In terms of material handling and separation, when the material enters the settling chamber, the heavier impurities settle under the action of gravity. The arc-shaped partition plate and splash guard can guide the flow of the material, allowing the material to smoothly enter the overflow plate side. Solid-liquid separation is achieved through static overflow, ensuring the purity of the discharged material.

[0021] 3. In terms of discharge control, when the discharge pipe slides up and down, the piston rod moves in the piston chamber. Through the action of the return spring, the material can be sucked in and expelled by pressure, which can accelerate the output speed of the material when conveying high viscosity materials. At the same time, in conjunction with the pressurized spraying of the material, large particles that are blocked inside the filter holes can be cleared, further ensuring the output speed of the material and preventing the occurrence of material blockage.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In modern agricultural development, water-soluble fertilizers are widely used due to their easy absorption and rapid effects. Water-soluble fertilizer anti-caking agents, as key additives to ensure their quality, have received considerable attention in their preparation process. The reaction device, as the core equipment, significantly impacts the production process and product quality through its discharge stage. In traditional discharge structures, sticky materials easily adhere to the inner wall of the discharge channel, accumulating and clogging, leading to poor discharge. This requires production personnel to suspend production for disassembly and cleaning, wasting time and manpower and reducing production efficiency. Furthermore, it is difficult to effectively filter and separate materials during discharge, allowing unreacted impurities and clumps to easily mix into the product, affecting the purity and performance of the water-soluble fertilizer anti-caking agent and adversely impacting crop growth.

[0031] Please see Figures 1-6 This utility model provides a technical solution: a reaction device for preparing anti-clogging material for water-soluble fertilizer anti-caking agent.

[0032] Example 1: This example discloses: a vessel body 1, a discharge barrel 2 fixedly installed at the lower end of the vessel body 1, a sliding discharge pipe 3 installed inside the discharge barrel 2, a temporary storage chamber 4 opened inside the upper end of the discharge pipe 3, a filter hole 5 opened on the outer surface of the upper end of the discharge pipe 3, a pressure relief hole 6 opened at the lower end of the discharge barrel 2, a piston chamber 7 opened inside the lower end of the discharge pipe 3, one end of a piston rod 8 is installed inside the piston chamber 7, and the other end of the piston rod 8 penetrates the lower surface of the discharge pipe 3, a toothed block 10 is fixedly installed on the outer surface of the middle section of the discharge pipe 3, a rotating gear 11 is installed inside the discharge barrel 2 side surface of the side of the discharge pipe 3 with the toothed block 10, and a motor 12 is fixedly installed inside the discharge barrel 2 side of the discharge pipe 3 with the toothed block 10.

[0033] The discharge pipe 3 and the discharge barrel 2 are connected by sliding friction, and the upper end of the discharge pipe 3 passes through the upper end of the discharge barrel 2 and is located inside the lower end of the vessel body 1.

[0034] The lower end of the temporary storage chamber 4 is connected to the upper end of the piston chamber 7. The upper end of the piston rod 8 is connected to the piston chamber 7 by sliding friction. A return spring 9 is connected between the upper end of the piston rod 8 and the piston chamber 7. The lower end of the piston rod 8 is connected to the discharge pipe 3 by clearance fit. The lower end of the piston rod 8 is fixedly connected to the discharge bucket 2.

[0035] Gear 11 is designed with missing teeth, and gear 11 is connected to discharge pipe 3 through tooth block 10. The rotating shaft of gear 11 is fixedly connected to the output shaft of motor 12.

[0036] When the material enters the discharge pipe 3 from the vessel body 1, the filter hole 5 can intercept larger particles of impurities to prevent them from entering the discharge channel and causing blockage. The motor 12 drives the toothed gear 11 to rotate. Through the periodic meshing of the toothed gear 11 and the tooth block 10, the return spring 9 drives the discharge pipe 3 to slide up and down in the discharge bucket 2. During the sliding process, the outer wall of the discharge pipe 3 can scrape off the attached material, and at the same time, the vibration causes the accumulated material to fall off, further preventing blockage.

[0037] When the discharge pipe 3 slides up and down, the piston rod 8, because its lower end is fixed to the discharge barrel 2, will move relative to the piston chamber 7. When the discharge pipe 3 slides up, the volume of the piston chamber 7 increases, generating negative pressure to draw the material in the vessel 1 into the temporary storage chamber 4 through the filter hole 5. When it slides down, the volume of the piston chamber 7 decreases, and the internal pressure increases, forcing the material out of the temporary storage chamber 4 through the filter hole 5. The pressure relief hole 6 ensures that the discharge pipe 3 will not be affected by pressure and will not be able to slide when it slides back and forth.

[0038] Example 2: This example is based on Example 1: A sedimentation chamber 13 is provided inside the lower end of the discharge barrel 2, and a partition plate 14 is fixedly provided on the bottom surface of the sedimentation chamber 13. An overflow plate 15 is fixedly connected to the upper end of the partition plate 14. A splash guard 16 is fixedly provided on the top surface of the sedimentation chamber 13. A one-way valve 17 is fixedly installed on the outer surface of the lower end of the discharge barrel 2.

[0039] Both the partition plate 14 and the splash guard 16 are arc-shaped, and the partition plate 14, the splash guard 16 and the discharge pipe 3 are concentrically arranged;

[0040] The overflow plate 15 has a flared design with a larger top and a smaller bottom, and there is a gap between the outer surface of the upper end of the overflow plate 15 and the inner surface of the sedimentation chamber 13.

[0041] After the material enters the sedimentation chamber 13 from the discharge pipe 3, the heavier impurities settle to the bottom of the sedimentation chamber 13 inside the partition plate 14 under the action of gravity, achieving preliminary separation. After the material is left to stand, the upper clear liquid overflows from the gap between the overflow plate 15 and the sedimentation chamber 13 and is discharged through the one-way valve 17. The lower impurities remain in the sedimentation chamber 13 inside the partition plate 14 to ensure the purity of the discharged material. The splash plate 16 ensures that the material is prevented from falling into the sedimentation chamber 13 inside the partition plate 14 when it is pressed out through the filter hole 5.

[0042] When the piston chamber 7 is pressurized for discharge, the high-pressure material can flush out large particles of impurities that are blocking the filter holes 5. Combined with the sliding unblocking of the discharge pipe 3, this further ensures that the discharge channel is unobstructed.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
