[0002] The treatment and disposal of sludge in my country is relatively lagging due to factors such as funding. The sludge stabilization rate is low, the harmless treatment rate is not high, the treatment and disposal technology is single and the cost is high. As a result, most sludge is not treated or only treated simply before being directly used for agriculture, landfilled, or sent to landfills, incinerated, or used for sludge land utilization. Some are even piled up at random. The sludge mainly contains sand and gravel, domestic waste, plastic products, glass products, microorganisms and their residues. The residue is mainly organic matter, and contains nutrients such as nitrogen and phosphorus and organic matter. The sludge contains a large amount of organic components, which is not only an important cause of sludge pollution, but also an important basis for sludge resource utilization.

[0003] Since sludge is usually mixed with a large amount of sewage, the existing technology usually dries the sludge directly for extracting soil, which not only easily causes the organic components in the sludge to be wasted with the evaporation of sewage, but also consumes a large amount of heat resources for drying the sludge, resulting in waste.

DETAILED DESCRIPTION

[0022] 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.

[0023] Reference Figure 1-4 A sludge treatment, recycling and reuse device includes a barrel body 1, a filter plate 101 is fixedly connected to the middle of the inner wall of the barrel body 1, a filter assembly 2 is installed in the inner cavity of the barrel body 1 above the filter plate 101, and the filter assembly 2 is used to filter large impurities in the sludge, and a pressing assembly 3 is installed in the inner cavity of the barrel body 1 below the filter plate 101, and the pressing assembly 3 is used to separate wastewater from the sludge, and also includes:

[0024] The pressing assembly 3 includes a servo motor 301, which is fixedly mounted on the top of the barrel body 1. The output end of the servo motor 301 is fixedly connected to a rotating shaft 302, and the rotating shaft 302 extends to the bottom of the barrel body 1. The inner bottom wall of the barrel body 1 is fixedly connected to a base 303, and the top of the base 303 is fixedly connected to a first filter barrel 304. The top of the first filter barrel 304 is fixedly connected to a second filter barrel 305, and the second filter barrel 305 is in contact with the filter plate 101.

[0025] A pressing block 306 is threadedly connected to the side wall of the rotating shaft 302 below the filter plate 101, and a limiting column 307 is fixedly connected to the bottom of the filter plate 101, and the limiting column 307 penetrates the pressing block 306 and extends to the bottom of the first filter barrel 304;

[0026] The side walls of the pressing block 306 and the second filter barrel 305 are both arranged to be inclined, and the bottom diameter of the pressing block 306 is equal to the diameter of the first filter barrel 304;

[0027] It should be noted that: the servo motor 301 is used to drive the rotating shaft 302 to rotate. After the sludge filters the large impurities in the filter assembly 2, it will fall on the side wall of the second filter barrel 305 and the top of the pressing block 306 through the filter plate 101. Since the pressing block 306 and the side wall of the second filter barrel 305 are both arranged to be inclined, the sludge will slide to the bottom of the first filter barrel 304. At the same time, since the rotating shaft 302 and the pressing block 306 are threadedly connected and there is a limiting effect of the limiting column 307, the pressing block 306 can slide on the side wall of the rotating shaft 302. The pressing block 306 slides downward on the rotating shaft 302 to squeeze the sludge located in the inner cavity of the first filter barrel 304, so that the water in the sludge passes through the first filter barrel 304 to reach the inner cavity of the barrel body 1 outside it. After the servo motor 301 reverses the rotating shaft 302, the pressing block 306 slides upward, so that the sludge can continue to enter the inner cavity of the first filter barrel 304 for squeezing, thereby realizing rapid dehydration of the sludge.

[0028] The filter assembly 2 includes a stirring plate 201, which is fixedly mounted on the side wall of the rotating shaft 302 located above the filter plate 101, and a cleaning plate 202 is fixedly connected to the side wall of the rotating shaft 302, and the cleaning plate 202 and the filter plate 101 are in contact with each other;

[0029] A sliding column 203 is slidably connected to the top of the barrel body 1, and a ring 204 is fixedly connected to the bottom end of the sliding column 203 in the inner cavity of the barrel body 1;

[0030] The top of the barrel body 1 is fixedly connected with a connecting plate 205 on both sides, the top of the sliding column 203 is rotatably connected with a rotating plate 206, the side wall of the connecting plate 205 is provided with a slot 207, and the rotating plate 206 can be rotated to the inner cavity of the slot 207;

[0031] It should be noted that when the sludge enters the inner cavity of the barrel body 1, it will fall on the top of the filter plate 101 located on the inner side of the ring 204. The servo motor 301 is used to drive the rotating shaft 302 to rotate. When the rotating shaft 302 rotates, it will drive the stirring plate 201 to rotate to break the soil blocks in the sludge for easy filtering, and the cleaning plate 202 will also rotate with the rotating shaft 302 to clean the filter plate 101 to avoid sludge blockage. After all the sludge is filtered, there are large particles of impurities on the top of the filter plate 101. At this time, the rotating plate 206 is rotated to disengage it from the slot 207 on the side wall of the connecting plate 205, and then the sliding column 203 and the ring 204 are slid upward to disengage the ring 204, and then the rotating plate 206 is rotated to make it stuck in the inner cavity of the slot 207. At this time, with the rotation of the stirring plate 201 and the cleaning plate 202, the impurities will be cleaned to the outside of the ring 204 for easy cleaning.

[0032] A discharge pipe 4 is fixedly connected to the bottom of the barrel body 1 below the first filter barrel 304, and a pipe plug 401 is threadedly connected to the inner wall of the discharge pipe 4;

[0033] A feed pipe 402 is fixedly connected to the top of the barrel body 1 located inside the ring 204, the side wall of the base 303 is arranged in an inclined shape, and a water outlet pipe 403 is fixedly connected to the bottom of the barrel body 1 located outside the base 303;

[0034] It should be noted that: the pressing block 306 squeezes the sludge out of the water to the outside of the first filter barrel 304, flows along the side wall of the base 303 to the inner bottom wall of the barrel body 1, and then flows out through the outlet pipe 403. After dehydration, the pipe plug 401 is rotated to disengage it from the discharge pipe 4, and then it is used to clean and collect the dehydrated sludge. At the same time, the pressing block 306 continues to rotate and press down with the rotating shaft 302, which can squeeze the sludge toward the discharge pipe 4, so that it can achieve the effect of rapid discharge. The sludge enters the top of the filter plate 101 on the inner side of the ring 204 through the feed pipe 402.

[0035] Operation method: the sludge enters the top of the filter plate 101 inside the circular ring 204 through the feed pipe 402, and the servo motor 301 is turned on. The servo motor 301 drives the rotating shaft 302 to rotate. When the rotating shaft 302 rotates, it drives the stirring plate 201 to rotate to break the soil blocks in the sludge for easy filtering, and the cleaning plate 202 will also rotate with the rotating shaft 302 to clean the filter plate 101 to avoid sludge blockage. After all the sludge is filtered, there are large particles of impurities on the top of the filter plate 101. At this time, the rotating plate 206 is rotated to disengage it from the slot 207 on the side wall of the connecting plate 205, and then the sliding column 203 and the circular ring 204 are slid upward to disengage the circular ring 204, and then the rotating plate 206 is rotated to be stuck in the inner cavity of the slot 207. At this time, with the rotation of the stirring plate 201 and the cleaning plate 202, the impurities will be cleaned to the outside of the circular ring 204 for easy cleaning;

[0036] The sludge will pass through the filter plate 101 and fall on the side wall of the second filter barrel 305 and the top of the pressing block 306. Since the pressing block 306 and the side walls of the second filter barrel 305 are arranged to be inclined, the sludge will slide to the bottom of the first filter barrel 304. At the same time, since the rotating shaft 302 and the pressing block 306 are threadedly connected and there is a limiting effect of the limiting column 307, the pressing block 306 can slide on the side wall of the rotating shaft 302. The pressing block 306 slides downward on the rotating shaft 302 to squeeze the sludge in the inner cavity of the first filter barrel 304, so that the water in the sludge passes through the first filter barrel 304 to reach the inner cavity of the barrel body 1 outside it. After the servo motor 301 reverses the rotating shaft 302, the pressing block 306 slides upward, so that the sludge can continue to enter the inner cavity of the first filter barrel 304 for squeezing, thereby realizing rapid dehydration of the sludge.
