[0023] 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.

[0024] like Figure 1 , Figure 2 As shown, a wastewater treatment device for environmental protection includes: an equipment platform 1 for wastewater treatment; a pretreatment tank 2 disposed on the equipment platform 1; a water storage pipe 3 connected to the pretreatment tank 2; a filter pipe 4 connected to the water storage pipe 3, the filter pipe 4 being connected to a water storage tank 5; a filter stone plate 6 slidably connected to the filter pipe 4; and a water pressure mechanism 7 slidably connected to the water storage pipe 3.

[0025] The equipment platform 1 is equipped with a support platform 11, and the pretreatment box 2 is located on the top of the support platform 11. The pretreatment box 2 is located above the water storage pipe 3. The top of the pretreatment box 2 is connected to the water inlet network. The sewage to be treated in the water inlet network flows directly into the pretreatment box 2. The bottom of the pretreatment box 2 is connected to the top of the water storage pipe 3 through a transfer pipe 23. The water passing through the pretreatment box 2 flows into the water storage pipe 3 for further treatment.

[0026] like Figure 3 As shown, a filter screen 21 is installed in the middle of the pretreatment tank 2. The wastewater to be treated passes through the filter screen 21, separating large particles from the wastewater. A suspension frame 22 is installed on the top of the filter screen 21. The top of the suspension frame 22 is higher than the top of the pretreatment tank 2. When the large particles intercepted by the filter screen 21 fill the upper part of the filter screen 21, the suspension frame 22 is lifted using a forklift or gantry crane and transferred to a designated location for waste storage, where the impurities are then further processed.

[0027] The water storage pipe 3 and the filter pipe 4 are connected by a flange. The inner diameter of the filter pipe 4 is larger than that of the water storage pipe 3. The flange on the water storage pipe 3 is located behind the port of the water storage pipe 3, and the port of the water storage pipe 3 extends into the filter pipe 4. The side walls of the water storage pipe 3 and the filter pipe 4 are equipped with supports 12, which are connected to the equipment platform 1. The supports 12 fix the water storage pipe 3 and the filter pipe 4 on the equipment platform 1, keeping their positions unchanged during sewage treatment.

[0028] The filter stone plate 6 is made of ceramic or activated carbon, which are effective materials for wastewater adsorption. The diameter of the filter stone plate 6 is larger than that of the water storage pipe 3. During wastewater treatment, the filter stone plate 6 blocks the outlet of the water storage pipe 3, so that all the wastewater in the water storage pipe 3 passes through the filter stone plate 6 before entering the inner cavity of the filter pipe 4. The water entering the inner cavity of the filter pipe 4 is adsorbed, removing some impurities and pollutants from the water.

[0029] A push rod 61 passes through the filter stone plate 6. A limit nut 62 is screwed to one end of the push rod 61 that passes through the filter stone plate 6. The limit nut 62 fits against the filter stone plate 6. When the push rod 61 moves back and forth, the filter stone plate 6 moves accordingly. When the filter stone plate 6 needs to be replaced, the limit nut 62 can be unscrewed to remove and replace the filter stone plate 6.

[0030] The end of the filter pipe 4 away from the water storage pipe 3 is detachably connected to a sealing plate 41. The sealing plate 41 is also connected to the filter pipe 4 via a flange. The other end of the push rod 61 passes through the sealing plate 41. A water outlet connected to the water storage tank 5 is provided on the side wall of the filter pipe 4 facing the bottom. Under normal circumstances, the water level cannot reach the height of the push rod 61.

[0031] The part of the push rod 61 outside the sealing plate 41 is threaded, and there is a distance of about 10cm between the thread and the outside of the sealing plate 41 to prevent the thread from affecting the sliding of the push rod 61.

[0032] A reaction plate 63 is detachably connected to the equipment platform 1. The reaction plate 63 is fixed to the equipment platform 1 with bolts. When it is necessary to remove the reaction plate 63, only the bolts need to be installed or removed. A hydraulic cylinder 64 is provided on the reaction plate 63, and the reaction plate 63 provides support for the hydraulic cylinder 64. The telescopic end of the hydraulic cylinder 64 is threaded, and the telescopic end of the hydraulic cylinder 64 is connected to the push rod 61 through a threaded sleeve 65. When connecting the hydraulic cylinder 64 and the push rod 61, first tighten the threaded sleeve 65 completely to the telescopic end of the hydraulic cylinder 64, then extend the telescopic end of the hydraulic cylinder 64 so that the hydraulic cylinder 64 fits against the end of the push rod 61, and then rotate the threaded sleeve 65 towards the push rod 61. During sewage treatment, the hydraulic cylinder 64 pushes the push rod 61 and the filter stone plate 6 towards the water storage pipe 3, so that the water in the water storage pipe 3 is completely filtered by the filter stone plate 6 before entering the filter pipe 4, ensuring the effectiveness of sewage treatment. When replacing the filter stone plate 6, unscrew the threaded sleeve 65, and then remove the reaction plate 63, hydraulic cylinder 64 and sealing disc 41 in sequence to remove the filter stone plate 6 from the filter tube 4 for replacement.

[0033] The water pressurization mechanism 7 includes a propulsion vehicle 71, a connecting rod 72, and a propulsion head 73. The equipment platform 1 is equipped with a slide rail 13, and the propulsion vehicle 71 moves on the slide rail 13. The propulsion vehicle 71 is powered by internal combustion or electric power. The slide rail 13 restricts the direction of movement of the propulsion vehicle 71. The connecting rod 72 is fixed to the front end of the propulsion vehicle 71, and the propulsion head 73 is located at the front end of the connecting rod 72. The propulsion vehicle 71 drives the connecting rod 72 and the propulsion head 73 to move. The propulsion head 73 pushes the water in the water storage pipe 3 to quickly pass through the filter stone plate 6 and enter the filter pipe 4, thereby accelerating the sewage treatment speed and improving the sewage purification effect.

[0034] The side wall of the propulsion head 73 is provided with multiple sealing strips 731. The sealing strips 731 and the propulsion head 73 are slidably connected to the inner wall of the water storage pipe 3. The sealing strips 731 prevent water from flowing out from one end of the propulsion head 73 when the propulsion head 73 and the filter stone plate 6 compress the water, thereby improving the sealing performance of the device.

[0035] Before wastewater treatment, the propeller head 73 is positioned behind the transfer pipe 23. At this point, water is poured into the storage pipe 3 to half its capacity, and then the water supply to the storage pipe 3 is stopped. The propeller 71 is then activated, causing the propeller head 73 to quickly push the water through the filter plate 6 for purification. The treated water then passes through the filter pipe 4 and enters the storage tank 5 for further treatment. Afterward, the propeller 71 is reversed so that the propeller head 73 is positioned behind the transfer pipe 23, and the next round of water discharge can begin.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
