For example, the first inlet 11 can be an opening directly opened on the housing of the first screening device 1, and the area and shape of the opening can be determined according to actual usage requirements, or it can be provided in the first screening device 1 An open piece or a delivery tube on the top. The first inlet 11 may not be a solid structure, for example, the first inlet 11 may be an open area above the screen, and the range of this area may be used as the first inlet 11 .

The first inlet 11 can be located at the top of the first screening device 1. After the sludge enters the first screening device 1 through the first inlet 11, the first screening device 1 will filter the sludge with a particle size larger than the first preset size.

A first outlet 12 may also be provided on the first screening device 1 . The first outlet 12 can output the remaining material after the sludge is screened by the first screening device 1 . Wherein, the output material can be transported into the second screening device 2 by way of pipeline transportation or transfer device. The shape of the first outlet 12 can also be various, for example, the first outlet 12 can be an opening directly opened on the housing of the first screening device 1, and the shape and area of the opening can be adjusted according to actual usage requirements. Determine; or the first outlet 12 is formed as an opening part or a discharge pipe arranged on the first screening device 1, or the first outlet 12 may not be a solid structure, for example, the first outlet 12 may be directly It is an open area located under the screen, and the entire area can be called the first outlet 12 .

Except that the shape of the first outlet 12 has various embodiments, the setting position of the first outlet 12 can also be various, for example, the first outlet 12 can be positioned at the bottom of the first screening device 1, and is used by the first screening device 1. The screened materials are discharged to the lower part of the first screening device 1 under the action of gravity, and then discharged from the first outlet 12. Of course, the first outlet 12 can also be arranged in the middle of the first screening device 1 . The present application does not impose specific limitations on the structure and location of the first outlet 12 , as long as it can discharge the remaining part of the sludge after screening, it all meets the requirements of the present application.

In this embodiment, the second screening device 2 can communicate with the first screening device 1 for materials. The second screening device 2 can further process the material output from the first screening device 1 . Specifically, the second screening device 2 can separate the fine sand whose particle size is larger than the second preset value from the input material and output the remaining part through the second outlet 22 .

Wherein, there may be various communication modes between the second screening device 2 and the first screening device 1 , for example, the first screening device 1 and the second screening device 2 may be connected through pipelines. A pipe can be arranged between the first outlet 12 and the second inlet 21 , one end of the pipe communicates with the first outlet 12 , and the other end of the pipe communicates with the second inlet 21 . The material discharged from the first outlet 12 can then be transported to the second screening device 2 by means of pipeline transportation; for another example, the first screening device 1 and the second screening device 2 may not be connected through any physical structure , the material discharged from the first outlet 12 of the first screening device 1 can be collected in the hopper first, and the hopper transfers the material to the position of the second inlet 21 of the second screening device 2, and then passes through the second inlet 21 Input into the second screening device 2;

In addition, the second screening device 2 can also be arranged close to the first screening device 1 and the second screening device 2 can be located below the first screening device 1, so that the first outlet 12 and the second inlet 21 are opposite, by The materials output from the first outlet 12 can directly fall into the second inlet 21, thereby realizing the transmission of materials.

Wherein, the second preset value may be 0.2 mm. Of course, the second preset value can also be between 0.2 mm and 15 mm, which can be determined by the user according to actual usage requirements. Sand and gravel particles within this particle size range can generally be recycled as low-grade building materials, thereby improving the utilization rate of sludge and reducing the amount that needs to be landfilled.

In this embodiment, the second screening device 2 may include a sand washer 23 . The sand washer 23 can use the Coanda effect to separate the fine sand with a particle size larger than 0.2 mm. Specifically, as shown in FIG. 2, the sand washer 23 may include a conical container 231, an input mechanism 232 arranged on the upper part of the conical container 231, a stirring mechanism 233 located in the conical container 231, and a The water delivery mechanism 234 and the sand delivery mechanism 235 connected to the bottom of the conical container 231.

Wherein, the conical container 231 may be a shell with a generally conical cavity formed therein. The housing can be made of metal, for example, stainless steel, aluminum alloy and the like. The housing can also be made of non-metallic material, such as plastic. The tapered container 231 may be disposed in a longitudinal direction. The diameter of the upper part of the conical container 231 can be larger than the diameter of the lower part, so that the materials entering the conical container 231 can decelerate continuously from top to bottom, so that the fine sand is deposited in the lower space for easy collection. In addition, the taper of the tapered container 231 and the volume of the container can be determined according to actual usage requirements, which are not limited in this application.

The input mechanism 232 may be disposed on the upper portion of the tapered container 231 . Specifically, the upper part of the conical container 231 may be provided with a top cover. The input mechanism 232 can be arranged on the top cover, and one end of the input mechanism 232 can extend into the chamber of the conical container 231, and the other end of the input mechanism 232 can be communicated with the second inlet 21, or the second inlet 21 can be It is directly formed on the other end of the input mechanism 232 so that the material output from the first outlet 12 can enter the conical container 231 . Preferably, the input mechanism 232 can be a pipe, and the shape of one end of the pipe protruding into the chamber of the tapered container 231 can be a bell mouth. The structure of the bell mouth can make the material entering the conical container 231 have a higher speed, and can guide the material to shoot to the side wall of the conical container 231, so that the fine sand in the material can contact the side wall, and the fine sand Then move down along the side wall and gather at the bottom of the conical container 231 . The other end of the pipe can communicate with the second inlet 21 , so that the material from the first outlet 12 can be input into the conical container 231 .

The stirring mechanism 233 may be disposed inside the conical container 231 . The stirring mechanism 233 may include a motor and a stirring member (stirring blade) rotatably connected to the motor. The motor drives the stirring member to stir the materials in the conical container 231 . Wherein, the material in the conical container 231 is generally a mixture of sand and water. The sand-water mixture rotates at a low speed in the conical container 231 driven by the stirring member. When there is surface friction between the sand-water mixture and the surface of the object it flows through (it can also be said to be fluid viscosity), as long as the curvature is not large, the fluid will flow along the surface of the object (the Coanda effect). Substances with relatively low density (water, scum and suspended solids) will move upward along the side wall, and substances with relatively high density (fine sand) will move down the side wall under their own gravity, and then deposit to the bottom of the conical container 231 to separate the fine sand from the material.

The water delivery mechanism 234 can also be arranged at the lower part of the conical container 231 . The water outlet end of the water delivery mechanism 234 is disposed at the bottom of the conical container 231 and located in the conical container 231 . The water inlet end of the water delivery mechanism 234 can be connected with an external water source. When a certain amount of fine sand is deposited on the bottom of the conical container 231, the water delivery mechanism 234 can deliver pressure water into the conical container 231, and the direction of the water flow can be upward. The pressurized water entering the conical container 231 can further agitate the fine sand, thereby forming a fluidized sand bed at the place where the fine sand is deposited. The fine sand in the fluidized sand bed is constantly moving and rubbing or colliding with each other, thereby removing the organic matter adhering to the surface of the fine sand.

The sand conveying mechanism 235 can be arranged at the lower part of the conical container 231 , which is used to discharge the fine sand after the organic matter is removed from the conical container 231 . Specifically, the sand conveying mechanism 235 may include a first housing 236 and a first screw 237 inside the housing. Wherein, the first shell 236 may be a sleeve extending along the longitudinal direction, and one end of the sleeve communicates with the lower part of the tapered container 231 . The first screw 237 can be sheathed in the first casing. The sand delivery mechanism 235 has a first output end and a first input end. The first input end may be an end of the first casing 236 communicating with the conical container 231 . The fine sand located at the bottom of the conical container 231 can enter into the first housing 236 through the first input port. One end of the first screw rod 237 is also located on the first input end, and the other end of the first screw rod 237 is located on the first output end, so that the first screw rod 237 can transport fine sand to the first output end and discharge the collection mechanism.

Preferably, in order to make the moisture content of the fine sand discharged from the sand conveying mechanism 235 lower, the first screw rod 237 is inclined relative to the horizontal plane and the first output end is higher than the first input end, so that the fine sand is discharged by the first screw rod 237 During the conveying process, the water in the fine sand can be discharged along the movement direction opposite to the first screw 237 under the action of gravity, and correspondingly, there is a water outlet below the first input end, so that the water discharged from the fine sand can be discharged It is discharged from the drain port and the position of the drain port is low, so as to avoid water remaining in the sand conveying mechanism 235 .

In this embodiment, the remaining part after the second screening device 2 separates the fine sand whose particle size is larger than the second preset value is basically liquid. The liquid also contains a large amount of organic matter and sand bodies with smaller particle sizes, which need to be processed by subsequent equipment. The upper part of the conical container 231 is provided with a drain pipe 238 communicating with the grid filter device 3 , and the liquid in the conical container 231 can enter the grid filter device 3 through the drain pipe 238 by gravity. Wherein, one end of the drain pipe 238 may be disposed on the side wall of the conical container 231 and close to the top of the conical container 231 . The other end of the drain pipe 238 may communicate with the second outlet 22 or the second outlet 22 may be directly formed on the drain pipe 238 . The grid filter device 3 may be located below the drain pipe 238, or the second outlet 22 may be located above the third inlet 31, so that the liquid in the conical container 231 enters the grid filter device 3 by gravity.

In this embodiment, the grid filtering device 3 may include a third inlet 31 and a third outlet 32 . The third inlet 31 is used to input the material output from the second outlet 22 , and the grid filter device 3 can separate the scum and suspended matter in the input material and output the remaining part through the third outlet 32 .

Specifically, the grill filtering device 3 may be a drum grill or an inflow screen grill. The filtering range of the grid filter device 3 is between 3 mm and 15 mm, that is, the organic matter and the filter residue with a diameter between 3 mm and 15 mm in the material are separated, among which, the drum type grid or the internal flow net The connection between the plate grid and the second screening device 2 can be various, for example, the drum type grid or the inflow type screen grid can be arranged in a water channel, and the material output by the second outlet 22 It can be input into the water channel first, and the grid filter device 3 can then process the liquid in the water channel; or, the second outlet 22 can be directly connected with the third inlet 31, and the drum type grill or the internal inflow mesh screen grille Furthermore, the liquid output from the second outlet 22 can be filtered, so as to separate the organic matter in the liquid.

Among them, organic matter can include scum and suspended matter, decayed matter, fallen leaves, and plant roots, etc. If these organic matters are not separated from the sludge, when the sludge is landfilled, it may cause landfill. pollution, at the same time, after the organic matter is separated, it can be transported to an incineration power plant for incineration to generate electricity, avoiding pollution and improving resource utilization.

Certainly, besides being able to separate the organic matter between 3 mm and 15 mm, the grid filter device 3 can also separate the inorganic matter within this range. For example, the filter residue separated by the grid filter device 3 generally contains 30% to 40% organic matter, and the rest is inorganic matter, but the main function of the grid filter device 3 is to separate the organic matter. The presence of inorganic substances in the substances is not limited in this embodiment.

In this embodiment, after the grid filter device 3 separates the organic matter in the liquid, the remaining material (liquid) can be transported to the separation device 4 through the third outlet 32, and the separation device 4 can output the third outlet 32 Sediment with a particle size larger than the third preset value in the material is separated.

The communication mode between the separation device 4 and the grid filter device 3 can be various, for example, the separation device 4 and the grid filter device 3 can be directly connected through pipelines, that is, after the material is output from the third outlet 32 of organic matter It can directly enter the separation device 4; a pool body can be provided between the separation device 4 and the grid filter device 3, and the material is first discharged into the pool body, and then pumped into the separation device 4 through the pump body. Of course, different communication methods will also cause different positions between the separation device 4 and the grid filter device 3. When the communication method is a pipeline, close settings can be used to save pipelines. When the tank body is indirectly connected, the two Or can be set relatively far away. Of course, the present application does not impose specific restrictions on the communication mode and relative position between the separation device 4 and the grid filter device 3, as long as the material can be transported from the grid filter device 3 to the separation device 4, it is in accordance with the requirements of the present application. application requirements.

In this embodiment, the third preset value may be 0.05 mm. The particles in this particle size range are generally fine sand. In order to be able to supply the liquid to a sewage treatment plant or to discharge it directly into a sewer, it is also necessary to separate the fine sand from the liquid. Wherein, the third preset value may be between 0.05 mm and 0.2 mm, and the operator may determine it according to actual usage requirements, which is not limited in this application.

In this embodiment, the separation device 4 may be a cyclone separator 41 . The cyclone separator 41 separates the sediment whose particle size is larger than the third preset value by centrifugal force. Specifically, as shown in Figure 3, the cyclone separator 41 includes a conical casing 411, a feed inlet 412 arranged on the top of the conical casing 411, a sand outlet 413 arranged at the bottom of the conical casing 411, and The overflow port 414 arranged on the top of the conical shell 411 ; the feeding direction of the feed port 412 is the tangential direction of the cross-sectional profile of the conical shell 411 .

The conical housing 411 may be a housing in which a chamber is formed. The housing can be made of metal, for example, stainless steel, aluminum alloy and the like. The housing can also be made of non-metallic material, such as plastic. The conical housing 411 may be disposed in a longitudinal direction. The diameter of the upper portion of the conical housing 411 may be larger than the diameter of the lower portion thereof. The taper of the conical housing 411 and the volume of the conical housing 411 can be determined according to actual usage requirements.

The top of the conical housing 411 may be provided with a top cover, which can close the top of the conical housing 411 . The feed inlet 412 can be arranged on the side wall of the conical housing 411 and near the top of the housing, the feed inlet 412 can be directly communicated with the third outlet 32, and the material (liquid) output by the third outlet 32 can pass through The feed port 412 enters the conical shell 411; or, the feed port 412 of the cyclone separator 41 is connected with a booster pump 5; the booster pump 5 can input the material discharged from the third outlet 32 into the conical shell Or the booster pump 5 can be arranged in the pool body, and the booster pump 5 can pump the material (liquid) that the third outlet 32 enters into the pool body into the conical shell 411.

Specifically, the feeding direction of the feed port 412 is the tangential direction of the cross-sectional profile of the conical shell 411, that is, when the material enters the conical shell 411, the moving direction of the material can be tangent to the cross-sectional profile, The material can move along the side wall, and because the cross section of the side wall is a circle, the material can rotate around the axis of the conical shell 411.
