DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor are involved in the protection scope of the utility model.

[0022] The existing device filters domestic sewage through filter screens layer by layer, which can remove large impurities, but the filter screens continuously accumulate large-particle impurities in the sewage during the treatment process. With the passage of time, the permeability of the filter screens gradually decreases, the filtering effect becomes poor, so it is necessary to clean the intercepted impurities regularly. However, the cleaning process often needs manual intervention, and the sewage treatment will be suspended during the cleaning process, which causes waste of time, affects the overall treatment efficiency, and is difficult to achieve the purpose of high efficiency. Please refer to Figures 1-4 The embodiment provides a high-efficiency domestic sewage treatment and purification tank, which comprises a filter box 1 and a water inlet channel 11 and a water outlet channel 12 fixedly connected to the filter box 1.

[0023] As shown in Figures 2-4 The filter screen 22 continuously accumulates large-particle impurities in the sewage during the treatment process. With the passage of time, the permeability of the filter screen 22 gradually decreases, the filtering effect becomes poor, so it is necessary to clean the intercepted impurities regularly. However, the cleaning process often needs manual intervention, and the sewage treatment will be suspended during the cleaning process, which causes waste of time, affects the overall treatment efficiency, and is difficult to achieve the purpose of high efficiency. In order to improve the treatment efficiency of domestic sewage, the following settings are made:

[0024] As shown in Figure 2As shown, the inside of the filter box 1 is provided with a filter mechanism 2, which includes a mounting shaft 21 rotating in the inside of the filter box 1, and a plurality of filter screens 22 are fixed on the outer wall of the mounting shaft 21 at equal intervals, and a motor 23 is fixed on the rear side of the filter box 1, and one end of the mounting shaft 21 is fixed on the output end of the motor 23. Through the water inlet channel 11, domestic sewage is introduced and flows vertically to the top of one of the filter screens 22 at the bottom for preliminary filtration. With the rotation of the plurality of filter screens 22, alternating filtration operation is realized. After each filter screen 22 completes filtration, it will be rotated and turned over to the other side. During the turning process, the water-facing surface of the filter screen 22 gradually tilts and turns to the back surface, so that the impurities that have been filtered slide to the top of the filter screen 22 below. The filter screen 22 below is in an inclined state, so that the impurities slide to the deslagging mechanism 3, avoiding clogging or fouling of the filter screen 22 and improving the overall working efficiency.

[0025] As shown in Figure 3 The deslagging port 13 is provided on the side of the filter box 1 away from the water outlet channel 12, and the inner bottom wall of the filter box 1 is provided with a slope, wherein the slope head is communicated with the deslagging port 13, and the slope bottom is communicated with the water outlet channel 12. Due to the design of the slope, the filtered sewage flows to the water outlet channel 12 under the action of gravity, reducing the time of sewage stagnation in the filter box 1, ensuring smooth water flow and avoiding stagnant flow. Finally, through the water outlet channel 12, the domestic sewage after solid-liquid separation can be quickly discharged, improving the efficiency of the entire treatment system.

[0026] As shown in Figure 4As shown, the inside of the residue discharging port 13 is provided with a residue discharging mechanism 3 for efficient sewage treatment in cooperation with the filtering mechanism 2, the residue discharging mechanism 3 includes a residue discharging plate 31 rotating in the inside of the residue discharging port 13, the residue discharging plate 31 is not in contact with the rotating filtering screens 22, the top of the residue discharging plate 31 is coated with a lubricating coating 311, the material of the lubricating coating 311 includes but is not limited to polytetrafluoroethylene, fluoride material, which can reduce the friction of the surface of the residue discharging plate 31, help the impurities to slide more smoothly, reduce the adhesion between the impurities and the surface of the residue discharging plate 31, further accelerate the flow of the impurities, avoid solid residues on the residue discharging plate 31 due to excessive friction. The bottom of the residue discharging plate 31 is provided with a connecting assembly for limiting the rotation amplitude thereof and generating vibration force when it rotates, the connecting assembly includes an extension rod 33 fixed at the bottom of the residue discharging plate 31, the outer wall of the end of the extension rod 33 away from the residue discharging plate 31 is sleeved with an extension cylinder 32, the outer wall of the extension rod 33 is provided with a limiting assembly for limiting the sliding range of the extension rod 33 in the extension cylinder 32, the limiting assembly includes a semicircular sliding block fixed on the outer wall of the extension rod 33, the inner wall of the extension cylinder 32 is provided with an arc fillet sliding groove for the sliding of the semicircular sliding block, the outer wall of the extension rod 33 is sleeved with a spring 34, and the two ends of the spring 34 are fixed with the residue discharging plate 31 and the extension cylinder 32 respectively. The residue discharging plate 31 is located at the residue discharging port 13, and the impurities slide to the top thereof under the action of gravity, due to the influence of the gravity on one side of the residue discharging plate 31 and the feedback force of the spring 34, the residue discharging plate 31 starts to vibrate within a certain amplitude, which can help the impurities to slide more easily from the surface of the residue discharging plate 31 to the impurity collecting box, avoiding the blockage or accumulation of the impurities on the residue discharging plate 31, thereby improving the efficiency of residue discharging, and further improving the treatment efficiency of the domestic sewage.
