Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figure 1An automatic cleaning device for horizontal filter cartridges (hereinafter referred to as the cleaning device) includes a water tank 100, which has a top wall 100c, a side wall 100b, and a bottom wall 100a, forming a water storage area 101. The cleaning device also includes a cover 200, which includes a top plate 200a and a side plate 200b, wherein the side plate 200b is connected to the edge line of the top plate 200a and is orthogonal to the top plate 200a. The top plate 200a, side plate 200b, and the top wall 100c of the water tank 100 together form a cleaning area for accommodating the filter cartridge (hereinafter referred to as the filter cartridge). A connecting port 104 is formed on 100c. The cleaning zone and the water storage zone 101 are connected at the connecting port 104. During the cleaning process, the water storage zone 101 supplies cleaning liquid (such as water) to the cleaning component 300 (described later). The cleaning liquid cleans the filter element in the cleaning zone under the action of the cleaning component 300. After cleaning, a recovery liquid is formed in the cleaning zone. The recovery liquid flows back into the water storage zone 101 through the connecting port 104 for collection. In some other embodiments of the cleaning device, a purification component 400 is formed in the water storage zone 101. The recovery liquid is at least partially converted into cleaning liquid under the action of the purification component 400 and is resupplyed to the cleaning component 300. The filter element is cleaned again by the cleaning component 300.

[0032] In some embodiments of the cleaning apparatus, reference is made to... Figure 1 The aforementioned cleaning device also includes a lifting assembly 500 and a moving assembly 501. The lifting assembly 500 is used to adjust the height of the water tank 100 and the cover 200 to accommodate the cleaning of filter cartridges of different specifications. For example, the lifting assembly 500 can be a manual or electric lifter installed on the side wall 100b of the water tank 100. In some embodiments of the cleaning device, multiple lifters (manual or electric) are provided and can operate independently, meaning a single lifter can be adjusted independently of other lifters to maintain the stability of the cleaning device on certain terrains (such as uneven surfaces). Simultaneously, the lifter can also be installed on the bottom wall 100a of the water tank 100, specifically to enable height adjustment of the water tank 100 and the cover 200. No specific limitations are imposed here. Figure 1 The aforementioned moving component 501 includes casters mounted on the bottom wall 100a of the water tank 100. For example, four casters are provided and distributed at the four corners of the bottom wall 100a of the water tank 100. Through the moving component 501, such as the casters, the cleaning device can move and stop at the cleaning position (next to the filter) to perform subsequent filter cleaning work.

[0033] In some embodiments of the cleaning apparatus, reference is made to... Figure 2The aforementioned water storage section 101 includes a first section 102 and a second section 103. The first section 102 is a storage section for pure cleaning fluid (with few impurities) and supplies pure cleaning fluid to the cleaning section. The second section 103 is equipped with a purification component 400 (described later). The second section 103 can store pure cleaning fluid or circulating fluid flowing out of the cleaning section (containing impurities such as mud and oil). That is, the second section 103 is connected to the cleaning section and filters impurities in the cleaning fluid through its purification component 400, and supplies pure cleaning fluid to the first section 102.

[0034] Reference Figure 2 , 3 4 and 5, the cleaning assembly 300 will now be described. The cleaning assembly 300 includes a pump body 301 and a piping assembly used in conjunction with the pump body 301. The pump body 301 has an input end and an output end. The input end of the pump body 301 draws in cleaning fluid, and the output end discharges the cleaning fluid. Specifically, the piping assembly includes an intake piping assembly and an output piping assembly. Valves (electric or manual) are provided on multiple pipes constituting the intake and output piping assemblies to control the connectivity of the pipelines. The intake piping assembly includes a first pipe 302, one end of which is connected to the first section 102 of the water storage section 101, and the other end of which is connected to the input end of the pump body 301. The output piping assembly includes a third pipe 304, which includes a first section 3... 04a and the second section 304b, wherein the second section 304b is configured as a section extending along the length direction of the cleaning interval, and multiple nozzles are installed in the second section 304b along its length direction. The multiple nozzles are evenly distributed in the length direction. Meanwhile, one end of the first section 304a is connected to the output end of the pump body 301, and the other end is connected to the end of the second section 304b. The end of the second section 304b connected to the first section 304a is referred to as the installation end. In some embodiments of the operation of the cleaning device, the pure cleaning liquid in the first interval 102 flows sequentially through the first section 304a and the second section 304b of the first pipe 302 and the third pipe 303 under the action of the pump body 301, and acts on the filter element through the nozzles on the second section 304b to achieve the cleaning of the filter element.

[0035] In some embodiments of the cleaning assembly 300, the nozzle is composed of multiple sets of linear nozzles spaced apart in the circumferential direction. Each set of linear nozzles is composed of multiple independent nozzles 306 spaced apart along the length of the second section 304b. In other embodiments of the cleaning assembly 300, the mounting end of the second section 304b is rotatably connected to the first section 304a, that is, the second section 304b can rotate along the axis. In this case, the nozzles on the second section 304b are composed of two sets of linear nozzles spaced at 180-degree angles. When the independent nozzles 306 spray, they can apply a rotational driving force to the second section 304b, thereby achieving 360° cleaning. In other embodiments of the cleaning assembly 300, the independent nozzles 306 are tilted towards the mounting end to push out impurities in the filter element from its opening end. Preferably, the tilt angle of the nozzle is between 10° and 20°. For example, the tilt angle is 15°.

[0036] Specifically, the selection of the independent nozzle 306 needs to consider the following factors:

[0037] 1. Pressure

[0038] (1) The most significant effect of pressure on nozzle performance is to change the nozzle flow rate; generally, within the operating range of the nozzle, pressure and flow rate have the following approximate relationship:

[0039] P2 / P1=(Q2 / Q1)2

[0040] Where: P1 and Q1 are the pressure and flow rate in the first state;

[0041] P2 and Q2 are the pressure and flow rate in the second state;

[0042] (2) Pressure and droplet diameter: When the pressure increases, the droplet diameter will decrease;

[0043] (3) Pressure and spray angle: When the pressure increases, the spray angle will change slightly;

[0044] 2. Specific gravity

[0045] The specific gravity of the medium also directly affects the flow rate; under the same pressure, the medium with a lower specific gravity has a larger flow rate.

[0046] 3. Viscosity

[0047] The effect of viscosity on nozzle performance is very complex, affecting almost all external characteristics of nozzles, such as spray angle, spray volume, distribution density, droplet diameter, and atomization degree. Therefore, the effect of viscosity is generally not considered for nozzles used for low-viscosity fluids that are similar to water. However, for nozzles used for high-viscosity fluids that are significantly different from water, it is generally necessary to conduct nozzle measurements and simulation experiments.

[0048] 4. Temperature

[0049] Temperature primarily affects nozzle performance by altering the viscosity and surface tension of the fluid.

[0050] 5. Surface tension

[0051] The effect of surface tension on nozzle performance is obvious, especially on the droplet diameter and spray angle.

[0052] For example, taking into account the above factors and the minimum thrust of the second section 304b (sprinkler manifold) rotation, after repeated experiments, a 220V, 22.5M maximum head, 600L / min maximum displacement, and 2.1KW water pump was finally selected.

[0053] For example, the nozzle design consists of 8 nozzles, with 4 independent nozzles of 306 forming a group, the included angle between the two groups being 180 degrees, and the nozzle diameter being 1 cm.

[0054] In some other embodiments of the cleaning assembly 300, the above-mentioned output pipe assembly further includes a fourth pipe 305 with one end connected to the output end of the pump body 301. The other end of the fourth pipe 305 is configured as a flexible hose, that is, the other end of the fourth pipe 305 is movable, and the operator can operate one end of the fourth pipe 305 to manually clean the filter element.

[0055] Reference Figure 2The purification component 400 will now be described. In some embodiments of the purification component 400, the purification component 400 includes a plurality of partitions spaced along a first direction within the water storage section 101. The first direction is the flow direction of the cleaning liquid within the water storage section 101 (i.e., the flow direction from the second section 103 to the first section 102, shown as right to left in the figure). The height of the plurality of partitions gradually decreases along the first direction. For ease of description, the partitions located at both ends (i.e., the partitions with the highest and lowest heights) are distinguished. These are referred to as the first partition 401 and the second partition 402, with the first partition 401 being the partition with the lowest height. The partitions between the first partition 401 and the second partition 402 are collectively referred to as the intermediate partition 403. At this time, the interval between the first partition 401 and the side wall 100b of the water tank 100 constitutes part of the aforementioned first interval 102, and is correspondingly referred to as the first water tank 404. The first water tank 404 constitutes part of the first interval 102. The interval between the second partition 402 and the side wall 100b of the water tank 100 is referred to as the second water tank 405. The second water tank 405 forms part of the second section 103, and the section between the second partition 402 and the side wall 100b of the water tank 100 is connected to the aforementioned cleaning section through a connecting hole. Meanwhile, the first partition 401 is a closed partition, and a water passage hole 408 is provided at the bottom of the second partition 402. When the cleaning device is working, the pure cleaning solution in the first water tank 404 is supplied to the nozzle through the first pipe 302 and the third pipe 303 to clean the filter element. The recovered liquid generated during cleaning enters the second water tank 405 through the connecting port 104. In the process, the oil and water in the recovered liquid separate into layers in the second water tank 405, which is the initial purification of the recovered liquid. The purified recovered liquid (i.e., the bottom water) enters the space between the first partition 401 and the second partition 402 through the water passage 408 at the bottom of the second partition 402, and the mud and sand in the water layer accumulate at the bottom of this space, which is the secondary purification of the recovered liquid. The recovered liquid after the secondary purification (i.e., the pure cleaning liquid) overflows from the top of the first partition 401 and enters the first water tank 404, and is selectively supplied to the cleaning zone; for example, referring to Figure 2The figure illustrates an embodiment of a purification assembly 400 with three partitions within the storage area. The bottom of the middle partition 403 also has water passage holes 408. The area between the first partition 401 and the middle partition 403 is designated as the third water tank 406, and the area between the middle partition 403 and the second partition 402 is designated as the fourth water tank 407. By setting the middle partition 403 at a height between the first partition 401 and the second partition 402, it can, on the one hand, block the oil layer in the second water tank 405, and on the other hand, reduce the amount of recovered liquid in the second water tank 405. The flow rate within the water storage zone 101 is adjusted to better allow the sediment in the recovered liquid to accumulate at the bottom of the third water tank 406 and the fourth water tank 407. Furthermore, considering the supply efficiency of the cleaning liquid, and since the main sediment has already accumulated at the bottom of the fourth water tank 407, the aforementioned suction pipe assembly also has a second pipe 303. One end of the second pipe 303 is connected to the third water tank 406, and the other end of the second pipe 303 is connected to the output end of the pump body 301. At this time, the pure cleaning liquid in the water storage zone 101 can be supplied through the first pipe 302 and / or the second pipe 303.

[0056] In some other embodiments of the purification component 400, the heights of the first partition 401, the middle partition 403, and the second partition 402 are 0.2m, 0.35m, and 0.45m, respectively. Correspondingly, the water passage holes 408 at the bottom of the second partition 402 and the middle partition 403 are rectangular holes of 0.1m*0.1m.

[0057] The operation process of the cleaning device will now be described with reference to a specific embodiment. Specifically, the operation steps of the cleaning device are as follows:

[0058] 1. Fill the storage area of ​​the water tank 100 with clean water to a height of 0.4m;

[0066] 9. Lower the lifting device, move the cleaning unit away, and close the quick-opening blind flange of the horizontal filter;

[0067] 10. Cover the body part 200.
