Technical Field

[0001] This utility model relates to the technical field of mud and sand separation devices, specifically a rapid mud and sand separation device for construction waste. Background Technology

[0002] Construction waste refers to the waste soil and debris excavated from underground spaces and foundation piling. During urban construction, a large amount of construction waste is generated due to the development of key projects such as real estate, subway tunnels, and transportation hubs. Construction waste mostly comes from deep underground layers and has characteristics such as high soil moisture content, high viscosity, and many impurities, making it unsuitable for direct use as topsoil. Currently, the best treatment method is to combine multiple methods such as mud-rock separation, rapid drying, and mechanical crushing before application. Among these methods, mud-rock separation in the early stage of treatment is a prerequisite for subsequent treatment.

[0003] Conventional separation devices use a screen and rotating drum to separate mud and sand by centrifugal force. During the centrifugation process, water needs to be added frequently by hand to separate the mud. Moreover, conventional devices can only separate mud and water, but cannot separate stone chips and fine sand, requiring secondary screening by hand, which is time-consuming and labor-intensive. Therefore, a rapid separation device for construction waste mud and sand is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a rapid separation device for construction waste and silt to solve the problems mentioned in the background art.

[0022] 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.

[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a rapid separation device for construction waste and mud, including a box 1; in order to filter out fine sand and impurities in the mud, the box 1 is equipped with a screening mechanism 2 and a spraying device 3, a table leg 11 is installed below the box 1, a first support plate 4 is installed at the rear of the box 1, and a second support plate 5 is installed on the table leg 11. Through the cooperation of the spraying device 3 and the screening mechanism 2, the need for secondary manual filtration is eliminated, which facilitates the subsequent processing of the mud.

[0024] To achieve the screening and separation function, the screening mechanism 2 includes a screening motor 200, which is mounted on a first support plate 4. A first rotating rod 201 is mounted on the screening motor 200, and a roller 202 is mounted on the first rotating rod 201. Four first fixing blocks 209 are mounted on the inner wall of the housing 1. A vibration motor 204 is mounted on a second support plate 5, and a second rotating rod 205 is mounted on the vibration motor 204. An eccentric wheel 206 is mounted on the second rotating rod 205, and connecting rods 207 are mounted at both ends of the eccentric wheel 206. Two second fixing blocks 210 are mounted on the other ends of the two connecting rods 207. A filter screen 212 is mounted on the second fixing blocks 210, and two additional fixing blocks 210 are mounted on the other ends of the filter screen 212. The four second fixing blocks 210 and the four first fixing blocks 209 are connected by four flexible connecting plates 211. A hole is opened at one end of the connecting rod 207, and a fixing bolt 208 is installed in the hole. The fixing bolt 208 fixes the connecting rod 207 to the second fixing block 210. A roller inner sleeve 203 is movably installed inside the roller drum 202. Both the roller drum 202 and the roller inner sleeve 203 have mesh openings. A locking tongue 7 is installed on the screening drum cover 6, and a locking block 9 is installed on the box body 1. A locking groove 10 is opened in the locking block 9, and the locking tongue 7 is adapted to the locking groove 10. A hole is opened at the bottom of the box body 1, and two baffles 8 are installed on both sides of the hole. When it is necessary to screen the slag, the locking tongue 7 is rotated to move the locking tongue 7 away from the locking groove 10. Open the screening barrel cover 6, then fill the slag to be screened into the inner sleeve 203 of the drum. After filling, close the screening barrel cover 6 and engage the locking tongue 7 into the locking groove 10 to prevent the slag from overflowing during operation. The screening motor 200 drives the first rotating rod 201 to rotate, which in turn drives the drum 202 to rotate. The inner sleeve 203 inside the drum 202 rotates accordingly. The slag rotates within the inner sleeve 203, and the dissolved mud is thrown out of the drum 202 by the centrifugal force generated during the rotation of the inner sleeve 203. The thrown mud then flows into the lower filter screen 212 through the baffle 8. The vibration motor 204 drives the second rotating rod 205 to rotate, and the eccentric wheel 206 on the second rotating rod 205 also rotates accordingly. When wheel 206 rotates, it drives the fixing bolt 208 to make an eccentric motion. The filter screen 212 moves back and forth under the action of the fixing bolt 208. The mud and water will flow into the collection device set below through the filter screen 212. The fine sand and impurities in the mud and water will be filtered by the filter screen 212 and flow into the collection device in front of the filter screen 212 under the action of vibration. After the separation is completed, the two motors are stopped. At this time, the roller 202 and the filter screen 212 stop rotating. Rotate the locking tongue 7 and move the locking tongue 7 away from the locking groove 10 to open the screening barrel cover 6. At this time, the inner sleeve 203 of the roller can be removed from the roller 202. After cleaning the residue in the inner sleeve 203, the roller 202 is put back into the inner sleeve 203 to complete the entire separation process.

[0025] The working principle is as follows: When it is necessary to screen the slag, rotate the locking tongue 7 to move the locking tongue 7 away from the locking groove 10, and then open the screening barrel cover 6. Then, fill the slag to be screened into the inner sleeve 203 of the drum. After filling, close the screening barrel cover 6 and lock the locking tongue 7 into the locking groove 10 to prevent the slag from overflowing during operation. The screening motor 200 drives the first rotating rod 201 to rotate, and the first rotating rod 201 drives the drum 202 to rotate. The inner sleeve 203 of the drum 202 rotates accordingly. The slag is rotating inside the inner sleeve 203 of the drum. A water pipe is inserted into the inlet sleeve 301, and water flows into the cavity of the spray baffle 302. The water is then sprayed out through the nozzles 303 on the spray baffle 302. Since both the drum 202 and the inner sleeve 203 have mesh openings, water can enter the inner sleeve 203 through the mesh. The soil inside the slag dissolves into muddy water under the action of the water flow. This dissolved muddy water is then neutralized by the centrifugal force generated during the rotation of the inner sleeve 203. The muddy water is thrown out of the drum 202 and flows through the baffle 8 into the lower filter screen 212. The vibrating motor 204 drives the second rotating rod 205 to rotate, and the eccentric wheel 206 on the second rotating rod 205 also rotates. When the eccentric wheel 206 rotates, it drives the fixing bolt 208 to make eccentric motion. The filter screen 212 reciprocates under the action of the fixing bolt 208, and the muddy water flows through the filter screen 212 into the collection device set below. Fine sand and impurities in the muddy water are removed. The material is filtered by the filter screen 212 and flows into the collection device in front of the filter screen 212 under the action of vibration. After the separation is completed, the two motors are stopped. At this time, both the drum 202 and the filter screen 212 stop rotating. Rotate the locking tongue 7 and move the locking tongue 7 away from the locking groove 10 to open the screening drum cover 6. At this time, the inner sleeve 203 of the drum can be taken out from the drum 202. After cleaning the residue in the inner sleeve 203, the drum 202 is put back into the inner sleeve 203 to complete the entire separation process.

[0026] Example 2: As Figure 1-5 To remove soil and impurities from the drum 202, the spraying device 3 includes a water inlet sleeve 301, which is installed on the housing 1. A spray baffle 302 is installed inside the housing 1, and several holes are opened on the spray baffle 302. Spray nozzles 303 are installed in the holes. A water inlet hole 300 is opened on the housing 1, and the water inlet sleeve 301 is installed in the water inlet hole 300 and connected to the inside of the housing 1. After filling is completed, the water pipe is inserted into the water inlet sleeve 301, and the water flows into the cavity inside the spray baffle 302. Then it is sprayed out through the spray nozzles 303 set on the spray baffle 302. Since both the drum 202 and the inner sleeve 203 of the drum have mesh holes, the water can enter the inner sleeve 203 of the drum through the mesh holes. The soil in the slag is dissolved into mud water under the action of the water flow. The mud and slag in the drum 202 are easily filtered out by the spraying device 3. The other features are the same as in Example 1.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
