Description

Technical Field

[0001] This utility model relates to the field of construction waste technology, specifically a screening and separation device for construction waste. Background Technology

[0002] Construction waste refers to the waste generated during the construction, laying, demolition, and repair of buildings, structures, pipelines, etc. by individuals or organizations. It includes slag, waste materials, mud, and other waste. Improper handling can cause environmental pollution and waste of resources, but through scientific classification, recycling, and resource utilization, it can be transformed from waste into treasure.

[0003] Existing technology discloses a construction waste separation device (publication number CN221832570U), comprising a fixed frame, support legs fixedly installed at the bottom of the fixed frame, and a processing assembly disposed on the side wall of the fixed frame. The processing assembly includes a separation mechanism installed on the side wall of the fixed frame, located on the right side of the fixed frame. An auxiliary mechanism is installed at the top of the fixed frame, located on the left side of the separation mechanism. A conveyor belt is driven along the inner wall of the fixed frame, and a crushing device is installed on the top left side of the fixed frame. This invention solves the problem that existing separation devices often separate construction waste by crushing and then screening it, making it difficult to separate the iron contained in the construction waste, thus limiting the application of existing separation devices.

[0004] A long rod is fixedly installed on the inner wall of the mounting plate, and a screen is slidably installed on the side wall of the long rod. A compression spring is fixedly installed on one side of the screen, and the other end of the compression spring is fixedly connected to the side wall of the mounting plate. The mounting plate, the long rod, and the compression spring determine the position of the screen. However, there are heavy components in the construction waste. When vibrating up and down, the heavier construction waste will cause damage to the screen, making it unable to screen. As a result, the screen needs to be replaced. This requires cutting the mounting plate, the long rod, and the compression spring, which can easily damage the mounting plate, the long rod, and the compression spring. It also requires a lot of time to repair the above components. Utility Model Content

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A screening and separation device for construction waste includes a screening device 1 and a support frame 3. A conveyor belt 2 is bolted to the top surface of the support frame 3, and the screening device 1 is bolted to the right side surface of the support frame 3.

[0029] The screening device 1 includes a screening housing 11, a screening component 13 is mounted on the surface of the screening housing 11, a collection box 12 is inserted into the bottom of the screening housing 11, and a connecting handle 14 is fixedly connected to the right side surface of the collection box 12.

[0030] The screening assembly 13 includes four electric push rods 131. Two electric push rods 131 form a group, and the two groups of electric push rods 131 are connected to the front and rear surfaces of the screening housing 11. The two electric push rods 131 in the same group are distributed on the left and right sides of the front of the screening housing 11. The four electric push rods 131 are controlled by a PLC controller so that the four electric push rods 131 can perform lifting and lowering operations together.

[0031] The top surface of the piston rod inside the electric push rod 131 is bolted to a connecting block 132. A connecting frame 137 is inserted into the top surface of the connecting block 132. A metal frame 133 is inserted into the top of the connecting frame 137. A threaded rod 134 is inserted into the inside of the metal frame 133. The threaded rod 134 is inserted into the top of the connecting frame 137. The metal frame 133 is slidably connected to the top of the connecting frame 137. The threaded rod 134 is inserted into the metal frame 133 and the connecting frame 137. The threaded rod 134 limits the metal frame 133 and the connecting frame 137, making it easy to disassemble and separate the connecting frame 137 and the metal frame 133.

[0032] A helical spring 135 is connected to the inward side of the top of the plug-in frame 137. A locking bolt 136 is threaded to the top of the plug-in frame 137. A threaded rod 134 is located inside the helical spring 135. The threaded rod 134 and the helical spring 135 determine the position of the plug-in frame 137, making it easy to pull the plug-in frame 137.

[0033] A connecting block 138 is fixedly connected to the bottom surface of the locking bolt 136. The locking bolt 136 is threaded to the top of the connecting block 132. The locking bolt 136 locks and fixes the connecting block 132 and the plug frame 137, which facilitates the disassembly and replacement of the connecting block 132, increases the service life of the connecting block 132, and makes the disassembly of the connecting block 132 faster.

[0034] A screen 139 is inserted into the surface of the connecting block 138. The screen 139 has through slots at both ends. The connecting block 138 is slidably connected to the inner wall surface of the through slot. The connecting block 138 slides on the inner wall surface of the through slot, which facilitates the adjustment of the position of the connecting block 138. The connecting block 138 can be disassembled and replaced. The screen 139 is slidably connected to the inner wall surface of the screening shell 11. The screen 139 is located above the collection box 12. The screen 139 moves up and down on the inner wall surface of the screening shell 11. The screen 139 performs screening operations on the construction waste and separates the construction waste.

[0035] When in use, rotate the locking bolt 136 to disengage the locking bolt 136 from the plug frame 137 and the connecting block 132, and then pull the plug frame 137 upward. The plug frame 137 drives the screen 139 upward, allowing the screen 139 to disengage from the screen housing 11.

[0036] At this time, the plug-in frame 137 is pulled inward, and the plug-in frame 137 slides on the surface of the metal frame 133 and the plug-in threaded rod 134, so that the helical spring 135 is compressed between the plug-in frame 137 and the metal frame 133.

[0037] When the plug-in frame 137 moves inward, the plug-in frame 137 drives the connecting plug 138 to slide at both ends of the screen 139, allowing the connecting plug 138 to disengage from the screen 139, making it easier to remove the plug-in frame 137 and the connecting plug 138 from the screen 139 for rinsing and maintenance.

[0038] After rinsing, the screen 139 and the connecting block 138 are movably connected. At this time, the compressed helical spring 135 begins to rebound. The helical spring 135 pushes the plug frame 137 to slide on the surface of the metal frame 133 and the plug thread rod 134, so that the connecting block 138 is engaged with the front and rear ends of the screen 139.

[0039] The replaced screen 139 is connected to the plug-in frame 137, and then the screen 139 is inserted into the inner wall surface of the screen housing 11, so that the plug-in frame 137 and the connecting block 132 are movably connected. Then, the locking bolt 136 is rotated, which can lock and fix the connecting block 132 and the plug-in frame 137, and the position of the screen 139 can be determined.

[0040] Construction waste is dumped onto the left end surface of conveyor belt 2, which transports the construction waste from left to right. The construction waste is dumped into the interior of the screening shell 11, so that the construction waste is located on the surface of the screening mesh 139.

[0041] Start the electric push rod 131. The electric push rod 131 is controlled by the PLC controller, so that the four electric push rods 131 can lift and lower together. The electric push rod 131 drives the plug frame 137 to move up and down through the connecting block 132. The plug frame 137 drives the screening screen 139 to move up and down through the connecting plug block 138.

[0042] The screening mesh 139 moves up and down on the inner wall surface of the screening shell 11. The screening mesh 139 screens and separates construction waste. Larger construction waste is located on the surface of the screening shell 11, while less construction waste passes through the screening mesh 139 and enters the collection box 12.

[0043] Hold the surface of the connecting handle 14 and pull the connecting handle 14. The connecting handle 14 will cause the collection box 12 to detach from the screening shell 11, making it easy to disassemble and replace the collection box 12.

[0044] 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 the 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.
