[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The purification mechanism of this application takes fiber filter rings as the core. Three fiber filter rings are welded to the inside of the clear water filter body to form a multi-layer filtration structure. The pre-treated circulating water is transported to the inlet pipe through the liquid pump and the liquid pumping pipe, and then enters the filter body. When the water flows through the multi-layer fiber filter rings, the ultra-fine fiber filter material of the fiber filter rings can intercept tiny suspended impurities and colloidal particles in the water, so that the quality of the effluent meets the water requirements of the downstream equipment. At the same time, the electromagnetic one-way valves installed on the surface of the liquid pumping pipe and the drain pipe can control the water flow through the PLC controller, which facilitates the backwashing or maintenance of the purification mechanism and ensures the continuous and stable purification process.

[0018] 2. The pretreatment mechanism of this application achieves preliminary filtration of circulating water through the synergy of the pretreatment tank and the purification tank. The circulating water introduced by the inlet pipe first enters the pretreatment tank. Inside the tank, the servo motor drives the rotating rod and stirring blade to rotate, which can break up the impurities that are clustered in the water. At the same time, the flocculant added by the dosing pipe promotes the coagulation of small impurities. Then the water flows through the connecting square pipe into the purification tank. The inclined grid plate inside the tank uses the principle of gravity sedimentation to quickly intercept large particles of impurities such as mud, rust, and fibers in the water, preventing these impurities from directly entering the purification mechanism. This reduces the clogging of the filter holes of the fiber filter rings in the purification mechanism, reduces the filtration load of the fiber filter rings, extends their cleaning and replacement cycle, and indirectly reduces the equipment operation and maintenance costs.

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] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A circulating water deep purification treatment device includes a clear water filter body 1, a purification mechanism 2 welded to the inner side of the clear water filter body 1, and a pretreatment mechanism 3 fixedly connected to the left side of the purification mechanism 2. The pretreatment mechanism 3 includes a purification tank 301, a grid inclined plate 302, a connecting square tube 303, a pretreatment tank 304, a partition plate 305, a filling pipe 306, an inlet pipe 307, a servo motor 308, a rotating rod 309, a stirring blade 310, a PLC controller 311, and a collection device. The collection box 312 and the purification box 301 are fixedly connected to the left side of the purification mechanism 2. The grid inclined plate 302 is installed inside the purification box 301. The connecting square tube 303 is fixedly connected to the top left side of the purification box 301. The pretreatment box 304 is fixedly connected to the left side of the connecting square tube 303. The partition 305 is welded to the top inside the pretreatment box 304. The filling pipe 306 is fixedly connected to the top left side of the pretreatment box 304. The water inlet pipe 307 is fixedly connected to the left side of the pretreatment box 304.

[0028] In this embodiment: the clear water filter body 1 provides a stable installation space for the purification mechanism 2. The purification tank 301 can store the inclined bar screen 302 and the flocculated water. The inclined bar screen 302 is installed at an angle inside the purification tank 301 to expand the interception area and improve the settling efficiency of large particles. The connecting square tube 303 connects the purification tank 301 and the pretreatment tank 304, providing a conveying channel for the water flow in the pretreatment tank 304 to the purification tank 301. The pretreatment tank 304 serves as the initial treatment space for circulating water. The inner partition 305 can separate the water inlet area and the stirring area to prevent the newly entered high-impurity water from directly impacting the stirring components. At the same time, it provides space for the servo motor 308 and the rotating rod 3. The 09 provides installation space. The partition 305 guides the circulating water introduced by the inlet pipe 307 to flow to the stirring area first. The filling pipe 306 can add flocculants, degreasing agents and other agents. With the stirring of the stirring blade 310, it promotes the coagulation of small impurities or the separation of oil and dirt, and enhances the pretreatment effect. The inlet pipe 307 connects the external circulating water pipe and the pretreatment box 304 to provide the equipment with the water source to be purified. The servo motor 308 can drive the rotating rod 309 to drive the stirring blade 310 to rotate. The rotating rod 309 can drive the stirring blade 310 to stir. The PLC controller 311 can receive sensor data and control the speed of the servo motor 308 and the opening and closing of the electromagnetic one-way valve 206. The collection box 312 can collect impurities.

[0029] Specifically, such as Figure 2 , Figure 3 As shown, servo motors 308 are installed on both sides of the top of the pretreatment box 304, and rotating rods 309 are rotatably connected to both sides of the top of the inner side of the pretreatment box 304. The top of the rotating rods 309 is connected to a connecting shaft via a flat key. The output end of the bottom of the servo motors 308 passes through the pretreatment box 304 and is fixedly connected to the top of the connecting shaft. The stirring blades 310 are welded to the surface of the rotating rods 309. The PLC controller 311 is installed on the left side of the front side of the pretreatment box 304, and the collection box 312 is slidably connected to the bottom of the inner side of the pretreatment box 304.

[0030] Specifically, such as Figure 4 As shown, the purification mechanism 2 includes three fiber filter rings 201, a drain pipe 202, an inlet pipe 203, a liquid pump 204, a liquid extraction pipe 205, a solenoid one-way valve 206, and a support plate 207. The fiber filter rings 201 are welded to the inner side of the clear water filter body 1.

[0031] Specifically, such as Figure 4 As shown, the drain pipe 202 is fixedly connected to the bottom of the clear water filter body 1, the liquid inlet pipe 203 is fixedly connected to the top of the clear water filter body 1, the support plate 207 is welded to the surface of the clear water filter body 1, and the liquid pump 204 is installed on the top of the support plate 207.

[0032] In this embodiment: by setting the fiber filter ring 201, the ultra-fine fiber filter material can intercept the tiny suspended impurities and colloidal particles remaining after pretreatment. The drain pipe 202 provides a discharge channel for the purified water that meets the standards. The liquid inlet pipe 203 connects the liquid pump 204 and the filter body, and stably delivers the pretreated water to the inside of the filter body. The liquid pump 204 provides a stable delivery pressure to ensure that the water flows through the fiber filter ring 201 at a suitable flow rate. The liquid extraction pipe 205 connects the purification tank 301 and the liquid pump 204, and delivers the pretreated water to the purification mechanism 2. The electromagnetic single-way valve 206 can be linked with the PLC controller 311 to be turned on and off. The support plate 207 provides a horizontal and stable installation platform for the liquid pump 204.

[0033] Specifically, such as Figure 4 As shown, the left side of the inlet pipe 203 is fixedly connected to the right side of the pump 204, the pump 205 is fixedly connected to the left side of the pump 204, and the left side of the pump 205 is fixedly connected to the top of the right side of the purification box 301. The electromagnetic single-way valve 206 is installed on the surface of the pump 205 and the bottom of the drain pipe 202 respectively.

[0034] Specifically, such as Figure 1 As shown, a handle 4 is welded to the front of the collection box 312, and the surface of the handle 4 is engraved with anti-slip texture.

[0035] In this embodiment: by setting a handle 4, a point of leverage is provided for the operator to easily pull out the collection box 312 to clean impurities. By setting an anti-slip texture, the friction between the hand and the handle 4 can be increased.

[0036] Specifically, such as Figure 1 As shown, a stable base 5 is welded to the bottom of the purification box 301 and the pretreatment box 304, and the surface of the stable base 5 is coated with anti-corrosion paint.

[0037] Specifically, such as Figure 5 As shown, a reinforcing base 6 is welded to the bottom of the pump 204, and the bottom of the reinforcing base 6 is welded to the top of the support plate 207.

[0038] In this embodiment: by setting a stable base 5, the two boxes are connected as a whole, which enhances the placement stability of the pretreatment mechanism 3 and prevents the boxes from tipping over due to water flow impact or stirring vibration. By setting an anti-corrosion coating, the base can be resisted from corrosion caused by circulating water leakage or environmental moisture, thus extending the service life of the pretreatment mechanism 3. By setting a reinforcing base 6, the installation firmness of the liquid pump 204 is enhanced.

[0039] Specifically, such as Figure 5 As shown, a sealing ring 7 is welded to one side of the inlet pipe 203 near the top of the clear water filter body 1, and the surface of the sealing ring 7 is coated with anti-corrosion paint.

[0040] Specifically, such as Figure 5 As shown, a stabilizing post 8 is welded to the bottom of the surface of the main body 1 of the clear water filter, and the bottom of the stabilizing post 8 is engraved with anti-slip texture.

[0041] In this embodiment: by setting a sealing ring 7, the gap at the interface between the liquid inlet pipe 203 and the main body can be filled to prevent water from leaking from the interface during transportation. By setting an anti-corrosion coating, the sealing ring 7 can be resisted from aging caused by corrosive components in the water flow, thus extending the sealing life. By setting a stabilizing column 8, the equipment can be prevented from shifting due to vibration of the liquid pump 204 and water flow impact. By setting an anti-slip texture, the friction with the ground can be increased.

[0042] Working Principle: First, the operator introduces the circulating water to be purified into the equipment through the inlet pipe 307. Guided by the inner baffle 305 of the pretreatment tank 304, the water flows smoothly towards the stirring area. Simultaneously, based on the characteristics of the impurities in the circulating water, the operator adds flocculant if it contains small suspended particles, and degreasing agent if it contains oil. The corresponding agent is injected through the injection pipe 306 on the top left side of the pretreatment tank 304. Then, the PLC controller 311 receives preset instructions or sensor data and starts the servo motors 308 on both sides of the top of the pretreatment tank 304. Once the servo motor 308 starts, its bottom output end, connected via a keyed shaft, drives the rotating rod 309 on the top inner side of the pretreatment tank 304 to rotate. The stirring blades 310 welded to the surface of the rotating rod 309 rotate synchronously. The stirring blades 310 thoroughly mix the added reagent with the circulating water, causing tiny impurities in the water to agglomerate into larger particles and separating oil from water, thus improving the subsequent impurity interception efficiency. Then, the circulating water, after being treated by stirring, flows naturally into the purification tank through the connecting square pipe 303 between the pretreatment tank 304 and the purification tank 301. Inside the purification tank 301, the inclined grid 302 installed inside the purification tank 301 quickly intercepts large particles of impurities that have already condensed in the water. At the same time, the PLC controller 311 opens the solenoid single-way valve 206 on the surface of the suction pipe 205 and starts the suction pump 204 installed on the support plate 207. Then, the suction pump 204 draws out the circulating water with large particles of impurities intercepted in the purification tank 301 through the suction pipe 205, and then delivers it to the inside of the clear water filter body 1 through the inlet pipe 203 connected on the right. After the circulating water enters the filter body, it passes through three fiber dividers. The microfiber filter ring 201 uses ultra-fine fiber filter media to intercept tiny suspended impurities and colloidal particles remaining in the water, achieving deep purification. After purification, the PLC controller 311 opens the electromagnetic one-way valve 206 at the bottom of the drain pipe 202, and the qualified water is discharged through the drain pipe 202 at the bottom of the filter body and transported to the downstream equipment for use. Finally, when the impurities in the collection box 312 accumulate to a certain amount, the operator can use the handle 4 to pull the collection box 312 out of the pretreatment box 304, empty the impurities, and push it back in to reset.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
