DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-4 A multi-stage construction wastewater treatment device for environmental protection construction includes a filter barrel 1, a filter plate 101 is fixedly connected to the inner wall of the filter barrel 1, a servo motor 102 is fixedly connected to the top of the filter barrel 1, and further includes:

[0025] The output end of the servo motor 102 is fixedly connected with a rotating shaft 2, and the rotating shaft 2 penetrates the filter plate 101. A cleaning plate 201 is fixedly connected to the side wall of the rotating shaft 2 above the filter plate 101, and the cleaning plate 201 and the filter plate 101 are fitted together. A connecting box 202 is fixedly connected to the side wall of the filter barrel 1, and the connecting box 202 is connected to the filter barrel 1. A filter hole is fixedly connected between the connecting box 202 and the filter barrel 1 below the filter plate 101;

[0026] An L-shaped frame 203 is fixedly connected to the bottom of the connection box 202, and a strap 204 is slidably connected to the bottom of the connection box 202;

[0027] A first spring 205 is fixedly connected between the strap 204 and the L-shaped frame 203, and a filter box 206 is fixedly connected to the side wall of the filter barrel 1;

[0028] It should be noted that: when the wastewater is passed to the filter barrel 1, large particles of impurities in the wastewater will be filtered out by the filter plate 101 inside the filter barrel 1, driving the servo motor 102, the servo motor 102 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the cleaning plate 201 to rotate, and the impurities filtered out on the surface of the filter plate 101 are scraped to the inner cavity of the connecting box 202. Since a filter hole is provided between the connecting box 202 and the filter barrel 1, the impurities will be collected in the inner cavity of the connecting box 202. When the impurities inside the connecting box 202 are too much and block the filter holes, the pressure in the inner cavity of the connecting box 202 increases, causing the strap 204 to slide toward the bottom of the L-shaped frame 203, and the first spring 205 is squeezed to generate a rebound force, and the connecting box 202 is opened. At this time, the impurities in the inner cavity of the connecting box 202 together with the sewage will be discharged from the connecting box 202, thereby completing the effect of the filter barrel 1 automatically removing large particles of impurities without stopping the filtering process.

[0029] Reference Figure 1-4The side wall of the filter barrel 1 below the filter plate 101 is fixedly connected to a liquid storage tank 3, a partition is fixedly connected to the side wall of the liquid storage tank 3, and a sliding plate 301 is slidably connected between the partition and the liquid storage tank 3;

[0030] The side wall of the sliding plate 301 is fixedly connected with a sliding column 302, and the sliding column 302 extends to the inner cavity of the filter barrel 1, and the end of the sliding column 302 is fixedly connected with a collision block 303;

[0031] The side wall of the rotating shaft 2 is fixedly connected to the extrusion column 304, and the extrusion column 304 can fit with the collision block 303. The side wall of the rotating shaft 2 is fixedly connected to the stirring plate 310, and the second spring 305 is fixedly connected between the sliding plate 301 and the liquid storage tank 3.

[0032] It should be noted that when the rotating shaft 2 rotates, the squeezing column 304 on its side wall is driven to rotate, and the squeezing column 304 collides with the collision block 303, so that the collision block 303 drives the sliding column 302 and the sliding plate 301 to slide, and the second spring 305 is squeezed. At the same time, the pressure in the inner cavity of the liquid storage tank 3 increases, and the flocculant inside the liquid storage tank 3 is sprayed into the inner cavity of the filter barrel 1, and is fully mixed with the sewage inside the filter barrel 1 in combination with the rotating stirring plate 310, so that the impurities in the sewage are precipitated and filtered again. When the squeezing column 304 is away from the collision block 303, under the action of the rebound force of the second spring 305, the collision block 303 returns to its original position, and waits for the next collision with the squeezing column 304, so that the flocculant in the inner cavity of the liquid storage tank 3 can be continuously added to the sewage in the inner cavity of the filter barrel 1.

[0033] Reference Figure 1-4 The inner wall of the filter box 206 is connected with a filter device, and the filter device includes filter cotton 306, biochemical balls 307 and activated carbon 308 from top to bottom;

[0034] A water outlet is provided between the liquid storage tank 3 and the filter barrel 1, an air inlet pipe 309 is fixedly connected to the top of the liquid storage tank 3, and a one-way valve is provided in the water outlet and the inner cavity of the air inlet pipe 309;

[0035] It should be noted that the sewage with flocculant added will pass through the filtering device again and be filtered by the filter cotton 306, biochemical ball 307 and activated carbon 308 in the filtering device to obtain multi-filtered sewage. Secondly, the air inlet pipe 309 can only take in air but not let out air, and the water outlet hole can only flow out but not flow in, which is convenient for controlling the pressure in the inner cavity of the liquid storage tank 3.

[0036] Operation method: wastewater is passed to the filter barrel 1, and large particles of impurities in the wastewater will be filtered out by the filter plate 101 inside the filter barrel 1, driving the servo motor 102, the servo motor 102 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the cleaning plate 201 to rotate, and the impurities filtered out on the surface of the filter plate 101 are scraped to the inner cavity of the connection box 202. Since there are filter holes between the connection box 202 and the filter barrel 1, the impurities will be collected in the inner cavity of the connection box 202. When there are too many impurities in the connection box 202 to block the filter holes, the pressure in the inner cavity of the connection box 202 increases, causing the strap 204 to slide to the bottom of the L-shaped frame 203, and the first spring 205 is squeezed to generate a rebound force, and the connection box 202 is opened. At this time, the impurities in the inner cavity of the connection box 202 together with the sewage will be discharged from the connection box 202, thereby completing the effect of automatically removing large particles of impurities from the filter barrel 1 without stopping the filtering process;

[0037] At the same time, the rotating shaft 2 drives the squeezing column 304 on its side wall to rotate, and the squeezing column 304 collides with the collision block 303, so that the collision block 303 drives the sliding column 302 and the sliding plate 301 to slide, and the second spring 305 is squeezed. At the same time, the pressure in the inner cavity of the liquid storage tank 3 increases, and the flocculant inside the liquid storage tank 3 is sprayed into the inner cavity of the filter barrel 1, and is fully mixed with the sewage inside the filter barrel 1 with the rotating stirring plate 310, so that the impurities in the sewage can be precipitated and filtered again. When the squeezing column 304 is away from the collision block 303, under the action of the rebound force of the second spring 305, the collision block 303 returns to its original position, waiting for the next collision with the squeezing column 304, so that the flocculant in the inner cavity of the liquid storage tank 3 can be continuously added to the sewage in the inner cavity of the filter barrel 1.
