Description

Technical Field

[0001] This utility model relates to the field of anti-overflow structure technology, specifically to the installation of an anti-overflow structure for liquid inside a liquid fertilizer storage tank. Background Technology

[0002] In the design and use of liquid fertilizer storage tanks, it is essential to install an anti-overflow structure to prevent internal liquid from overflowing (which could lead to raw material waste, environmental pollution, equipment corrosion, or even safety hazards).

[0003] In existing technologies, recovery tanks are typically installed to prevent liquid from overflowing from liquid fertilizer storage tanks. To intercept impurities in the liquid fertilizer (such as incompletely decomposed organic matter particles), filters are usually installed in the recovery tank. Existing technologies typically use high-pressure water jets to clean impurities adhering to the filter screen to prevent clogging. However, for viscous stains (such as residual organic matter or colloidal precipitates from the liquid fertilizer) or solidified stains (such as long-term accumulated crystals) adhering to the filter screen surface, high-pressure water jets primarily perform "impact stripping." These stains have strong adhesion and are difficult to completely remove by water jet alone, easily remaining in the filter screen pores, leading to a gradual decrease in filter permeability. Therefore, a novel structure is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-overflow structure for the internal liquid of liquid fertilizer storage tanks, thereby solving the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to an anti-overflow structure for the internal liquid of a liquid fertilizer storage tank, comprising:

[0006] An overflow prevention and backflow prevention assembly includes a drain pipe, a recovery tank, and a backflow pipe. The drain pipe is fixedly inserted into the side of the liquid fertilizer storage tank, the recovery tank is placed on one side of the liquid fertilizer storage tank, and one end of the backflow pipe is fixedly inserted into the bottom of the side of the recovery tank.

[0007] An anti-clogging component includes a filter screen, receiving rods, bearings, a shaft, a brush plate, and a propeller. The filter screen is movably connected to the recycling tank. The receiving rods are fixedly connected to both sides of the inner wall of the recycling tank. The outer ring of the bearing is fixedly connected between the receiving rods. The shaft is fixedly connected to the inner ring of the bearing. The brush plate is fixedly connected to the top of the shaft. The propeller is fixedly connected to the bottom of the shaft.

[0008] Furthermore, the diameter of the bristles on the brush plate is smaller than the diameter of the mesh on the filter screen.

[0009] Furthermore, the anti-clogging component also includes a limiting guide groove and a limiting block. The limiting guide groove is opened on the inner walls of both sides of the recycling tank. The limiting blocks are fixedly connected to both sides of the filter screen, and the limiting blocks are movably connected in the limiting guide groove.

[0010] Furthermore, the anti-overflow backflow assembly also includes a valve, which is fixedly installed on the drain pipe.

[0011] Furthermore, the anti-overflow backflow assembly also includes a pressure pump, which is fixedly installed on the backflow pipe.

[0012] Furthermore, it also includes a convenient removal and cleaning component, which includes a sleeve base, a rectangular rod, a slot, and an insertion rod. The sleeve base is movably placed on the ground, and the rectangular rod is fixedly connected to the bottom of the recycling tank. The rectangular rod is located at the bottom end of the limiting block, and the rectangular rod is movably connected in the sleeve base. Slots are opened through the sleeve base and the rectangular rod, and the insertion rod is movably connected between the slots.

[0013] Furthermore, the convenient removal and cleaning component also includes an L-shaped pull rod, with the L-shaped pull rod fixedly connected to the top of the limiting block, and the L-shaped pull rod movably connected to the recycling tank.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a linked structure of "propeller-shaft-brush plate" and bearings to drive the propeller to rotate using the impact force of the falling liquid fertilizer, which in turn drives the brush plate to rotate synchronously. Compared to the passive cleaning method of "impact peeling" by existing high-pressure water flow, the bristles of the brush plate can penetrate deep into the filter mesh to actively rub and clean the attached viscous stains (such as residual organic matter and colloidal sediments) and solidified stains (such as long-term accumulated crystals). This fundamentally prevents stains from remaining in the mesh, completely solves the problem of the gradual decrease in filter permeability, and ensures the continuous and stable filtration function.

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.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Please see Figure 1-4 As shown, this utility model is a structure for preventing spillage of liquid inside a liquid fertilizer storage tank, comprising:

[0028] An overflow prevention and backflow prevention assembly includes a drain pipe 101, a recovery tank 102, and a backflow pipe 103. The drain pipe 101 is fixedly inserted into the side of the liquid fertilizer storage tank, the recovery tank 102 is placed on one side of the liquid fertilizer storage tank, and one end of the backflow pipe 103 is fixedly inserted into the bottom of the side of the recovery tank 102.

[0029] The anti-clogging component includes a filter screen 201, a receiving rod 202, a bearing 203, a shaft 204, a brush plate 205, and a propeller 206. The filter screen 201 is movably connected in the recovery tank 102. The receiving rods 202 are fixedly connected to both sides of the inner wall of the recovery tank 102. The outer ring of the bearing 203 is fixedly connected between the receiving rods 202. The shaft 204 is fixedly connected to the inner ring of the bearing 203. The brush plate 205 is fixedly connected to the top of the shaft 204. The propeller 206 is fixedly connected to the bottom of the shaft 204.

[0030] The drain pipe 101 is used to drain the liquid fertilizer from the liquid fertilizer storage tank to prevent it from overflowing onto the ground from the top of the tank. The recovery tank 102 is used to store excess drained liquid fertilizer. The return pipe 103 is used to discharge the liquid fertilizer collected in the recovery tank 102 into the next liquid fertilizer storage tank to be installed. The filter screen 201 is used to intercept impurities in the liquid fertilizer (such as incompletely decomposed organic matter particles). The support rod 202 ensures the secure installation of the bearing 203. The outer ring of the bearing 203... The inner ring is connected to the shaft 204 via rolling elements. The shaft 204 is used to connect the brush plate 205 and the propeller 206. The brush plate 205 is used to efficiently clean the sticky or hardened stains attached to the mesh of the filter screen 201, so that they are removed from the mesh and prevent them from affecting the permeability of the filter screen 201. When the propeller 206 is impacted by liquid, it can drive the shaft 204 to rotate under the cooperation of the outer and inner rings of the bearing 203, which in turn drives the brush plate 205 to rotate and clean the filter screen 201.

[0031] The diameter of the bristles on the brush plate 205 is smaller than the diameter of the mesh openings on the filter screen 201.

[0032] The dimensional arrangement of the above components ensures that the bristles on the brush plate 205 can smoothly clean the mesh holes of the filter screen 201.

[0033] The anti-clogging component also includes a limiting guide groove 207 and a limiting block 208. The limiting guide groove 207 is opened on both sides of the inner wall of the recycling tank 102. The limiting block 208 is fixedly connected to both sides of the filter screen 201. The limiting block 208 is movably connected in the limiting guide groove 207.

[0034] The limiting guide groove 207 and the limiting block 208 work together to ensure the easy installation and removal of the filter screen 201.

[0035] The anti-overflow and backflow assembly also includes a valve 104, which is fixedly installed on the drain pipe 101; the anti-overflow and backflow assembly also includes a booster pump 105, which is fixedly installed on the backflow pipe 103.

[0036] Valve 104 is used to control the flow and closure of the drain pipe 101, and pressure pump 105 is used to ensure the accelerated flow of liquid fertilizer in return pipe 103.

[0037] Working principle: When valve 104 on drain pipe 101 is opened, and the liquid level in the liquid fertilizer storage tank rises to the height of drain pipe 101, excess liquid fertilizer in the storage tank flows naturally into the recovery tank 102 on one side through drain pipe 101, preventing liquid from overflowing from the top of the storage tank and achieving initial overflow prevention control. After the liquid fertilizer enters the recovery tank 102, it first passes through filter screen 201, which intercepts impurities such as incompletely decomposed organic matter particles in the liquid fertilizer. At the same time, during the fall of the liquid fertilizer, it impacts the propeller 206 at the bottom of the recovery tank 102. With the cooperation of the inner ring, rolling elements and outer ring in the bearing 203, the propeller 206 is driven to rotate by the impact force. The rotation of the propeller 206 drives the shaft 20 fixedly connected to it. 4. Rotation: The brush plate 205 at the top of the shaft 204 rotates synchronously with the shaft 204. Since the diameter of the bristles on the brush plate 205 is smaller than the diameter of the mesh of the filter screen 201, the bristles can penetrate into the mesh to rub and clean the attached sticky stains (such as residual organic matter and colloidal sediment) and solidified stains (such as crystals), preventing the stains from clogging the mesh and ensuring the permeability of the filter screen 201. The liquid fertilizer filtered by the filter screen 201 is stored at the bottom of the recovery tank 102. The pressure pump 105 on the return pipe 103 is started. Under the power of the pressure pump 105, the liquid fertilizer is transported through the return pipe 103 to the next liquid fertilizer storage tank, completing the liquid recycling and reuse, forming a closed loop process of anti-overflow-filtration-return.

[0038] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The easy-to-remove cleaning component includes a sleeve base 301, a rectangular rod 302, a slot 303, and an insert rod 304. The sleeve base 301 is movably placed on the ground. The rectangular rod 302 is fixedly connected to the bottom of the recycling tank 102. The rectangular rod 302 is located at the bottom end of the limiting block 208. The rectangular rod 302 is movably connected in the sleeve base 301. Slots 303 are opened through both the sleeve base 301 and the rectangular rod 302. The insert rod 304 is movably connected between the slots 303. The easy-to-remove cleaning component also includes an L-shaped pull rod 305. The L-shaped pull rod 305 is fixedly connected to the top of the limiting block 208. The L-shaped pull rod 305 is movably connected to the recycling tank 102.

[0040] When the insertion rod 304 is inserted into and removed from the slot 303, it can control the support and lowering state of the rectangular rod 302, thereby enabling the height adjustment of the recycling tank 102. When it is necessary to centrally clean the impurities filtered by the filter screen 201, the recycling tank 102 can be lowered. At this time, it can ensure that the top of the recycling tank 102 and the bottom of the drain pipe 101 are horizontally offset, thereby avoiding affecting the normal removal of the filter screen 201. Then, by pulling the L-shaped pull rods 305 at both ends, the filter screen 201 and the impurities filtered above it can be removed together.

[0041] Working principle: When it is necessary to centrally clean the impurities intercepted on the filter screen 201, first close the valve 104 of the drain pipe 101 and the pressure pump 105 of the return pipe 103 to stop the inflow and outflow of liquid fertilizer, thus preventing liquid leakage or impurities from entering the downstream storage tank during the cleaning process. Then, pull out the insert rod 304 from the slot 303 on the sleeve base 301 and the rectangular rod 302. After the rectangular rod 302 loses its fixed support, it slides downwards along the inner wall of the sleeve base 301, causing the recovery tank 102 to move downwards as a whole. The top of the recycling tank 102 and the bottom of the drain pipe 101 are completely offset in the horizontal direction to ensure that there is no structural obstruction when the filter screen is removed later. Hold the L-shaped pull rods 305 on both sides of the top of the recycling tank 102 with both hands and pull the L-shaped pull rods 305 upward at a uniform speed. At this time, the limiting block 208 slides upward along the limiting guide groove 207 on the inner wall of the recycling tank 102, driving the filter screen 201 to rise synchronously until the filter screen 201 is completely separated from the recycling tank 102, so that the filter screen 201 and the intercepted impurities can be removed together.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
