Description

Technical Field

[0001] This utility model belongs to the technical field of soil remediation equipment, specifically relating to a leaching liquid spraying device for soil remediation, and in particular a leaching liquid spraying device with a self-cleaning and easy-to-maintain filter structure. Background Technology

[0002] With the intensification of industrial development and human activities, soil pollution has become an increasingly prominent problem, seriously threatening the ecological environment and human health. Soil remediation technology is a key means of controlling soil pollution, among which leaching remediation technology is widely used due to its simplicity and high efficiency. This technology involves spraying a specially formulated leaching solution onto contaminated soil. The leaching solution dissolves, complexes, and emulsifies the pollutants in the soil, leaching them away from the soil particles and carrying them out with the leaching solution, thereby achieving soil purification.

[0003] In the process of spraying leaching solution, automatic sprinklers are often used as auxiliary spraying devices to improve work efficiency and ensure uniform spraying. Automatic sprinklers, with their automated control and wide coverage, can stably spray the leaching solution to the target area according to preset parameters, effectively reducing manual labor intensity. However, during the preparation and storage of the leaching solution, impurities can easily be generated due to insufficient purity of raw materials, incomplete reactions, or changes in the storage environment. If these impurities enter the automatic sprinkler with the leaching solution, they can easily cause nozzle blockage, affecting the spraying effect and even leading to equipment failure. To solve the nozzle blockage problem, existing automatic sprinklers usually have a simple filtration structure at the nozzle, with screen filtration being the most common form. The screen intercepts solid impurities in the leaching solution, which can, to some extent, prevent impurities from entering the nozzle channel.

[0004] However, in practical applications, as spraying continues, intercepted impurities gradually accumulate on the filter screen, reducing its permeability and consequently affecting the flow rate and spraying pressure of the rinsing fluid, thus lowering repair efficiency. Cleaning the accumulated impurities on the filter screen requires disassembling the automatic sprinkler head and related components to remove the filter screen for cleaning or replacement. Frequent disassembly and reassembly not only interrupts the rinsing process but also impacts the repair schedule. Therefore, existing technologies lack a rinsing fluid spraying device that can conveniently remove filter screen impurities and is easy to maintain during continuous spraying operations.

[0019] 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.

[0020] This specific embodiment is a leaching solution spraying device for soil remediation, and its structural schematic diagram is shown below. Figures 1 to 4 As shown, the system includes a support pipe 1, with a rotating cylinder 2 connected to its upper end. Spraying mechanisms are installed at both the inner and outer ends of the rotating cylinder 2. Each spraying mechanism includes a connecting pipe 301 fixedly connected to the upper left and right ends of the rotating cylinder 2. A bent pipe 302 is installed at the end of the connecting pipe 301 away from the rotating cylinder 2, and a nozzle 303 for spraying a leaching agent onto the soil to be remediated is installed at the other end of the bent pipe 302. A discharge pipe 304 is fixedly connected to the lower end of the connecting pipe 301. A cap 305 is connected to the lower outer side of the connecting pipe 301. A left inclined block 306 is fixedly connected to the lower inner side of the connecting pipe 301 at a position to the left of the discharge pipe 304. A right inclined block 307 is fixedly connected to the lower inner side of the connecting pipe 301 at a position to the right of the discharge pipe 304. A filter screen 308 is fixedly connected to the inner side of the bent pipe 302 at a position to the left of the left inclined block 306. The lower end of the support pipe 1 is installed to the upper end of the main pipe for conveying the rinsing liquid. The connecting pipe 301 is fixed to the outer end of the rotating cylinder 2 at an upward inclination. Thus, after the spraying of the rinsing liquid by the nozzle 303 is completed, due to the inclination of the connecting pipe 301, the impurities accumulated at the outer end of the filter screen 308 will fall onto the left inclined block 306 and then slide down the surface of the inclined left inclined block 306.

[0021] The lower outer side of the discharge pipe 304 has an external thread, and the inner side of the cover 305 has an internal thread. The lower outer side of the discharge pipe 304 is connected to the inner thread of the cover 305. Thus, after impurities slide down the left inclined block 306 into the discharge pipe 304, they accumulate inside the discharge pipe 304. Then, by rotating the cover 305, the impurities can be removed from the lower end of the discharge pipe 304, allowing them to automatically fall and be discharged without disassembling the entire sprinkler. This makes cleaning the impurities at the filter screen 308 very convenient and quick.

[0022] In addition, a disassembly unit is provided on the outer side of the connecting pipe 301 and the bent pipe 302. The disassembly unit includes an outer connecting ring 401 connected to the outer end of the connecting pipe 301. A left retaining ring 402 is welded to the inner side of the outer connecting ring 401 away from the rotating cylinder 2. A fixing ring 403 is welded to the outer side of the bent pipe 302 near the rotating cylinder 2. An inner connecting ring 404 is welded to the outer side of the connecting pipe 301 away from the rotating cylinder 2. The inner side of the outer connecting ring 401 has an internal thread, and the outer side of the inner connecting ring 404 has an external thread. The inner side of the outer connecting ring 401 is threaded to the outer side of the inner connecting ring 404. The side of the connecting pipe 301 away from the rotating cylinder 2 abuts against the side of the bent pipe 302 near the rotating cylinder 2. The left and right sides of the fixing ring 403 abut against the sides adjacent to the left retaining ring 402 and the inner connecting ring 404. The inner side of the left retaining ring 402 is slidably connected to the outer side of the bent pipe 302. Thus, by placing the left retaining ring 402 on the side of the fixed ring 403 away from the rotating cylinder 2, and at the same time, after the fixed ring 403 contacts the inner connecting ring 404, the left retaining ring 402 is slid to contact the fixed ring 403, and at the same time, the outer connecting ring 401 is threaded to the outside of the inner connecting ring 404, so that the fixed ring 403 can be fixed between the left retaining ring 402 and the inner connecting ring 404, and the connecting pipe 301 and the bent pipe 302 are relatively fixed.

[0023] Cooperate Figure 5 As shown, a rotating unit is provided above the support tube 1. The rotating unit includes a middle ring 501 welded to the upper outer side of the support tube 1, a lower limit ring 502 fixedly connected to the lower inner side of the rotating cylinder 2, and an upper limit ring 503 fixedly connected to the inner side of the rotating cylinder 2 above the lower limit ring 502. Ball bearings 504 are connected to the upper and lower ends of the middle ring 501. Annular grooves are formed on the upper and lower sides of the middle ring 501, the upper side of the lower limit ring 502, and the lower side of the upper limit ring 503. The outer side of the ball bearings 504 is in rolling connection with the inner side of the annular groove, the outer circumferential surface of the middle ring 501 is in sliding connection with the lower inner side of the rotating cylinder 2, and the inner side of the lower limit ring 502 is in sliding connection with the upper outer side of the support tube 1. This allows the rotating cylinder 2 to rotate more smoothly above the support tube 1.

[0024] Working principle: When spraying the leaching agent on the soil that needs to be repaired, the leaching liquid is transported into the main pipe connected to the lower end of the support pipe 1, and then flows into the support pipe 1 and then upwards to the rotating cylinder 2. After passing through the interior of the connecting pipe 301 and the bend pipe 302, it is filtered by the filter screen 308 and finally sprayed out from the nozzle 303. At the same time as spraying, a thrust opposite to the spraying direction is generated, causing the support pipe 1 to rotate on top of the support pipe 1, so as to spray the surrounding soil comprehensively. After the spraying work is completed, the impurities attached to the outer end of the filter screen 308 fall into the left inclined block 306, and then slide down the inclined left inclined block 306 into the discharge pipe 304. Then, the cover 305 is rotated to remove it from the lower end of the discharge pipe 304, so that the impurities in the discharge pipe 304 can fall and be discharged automatically, completing the soil spraying and the removal of impurities inside the sprinkler.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
