DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] Embodiment 1: This embodiment 1 provides an insulation board trimming and dust reduction device, which is directly improved on the existing insulation board trimming device and has a unique structure. Please refer to Figure 1-4 As shown, it includes an annular retaining wall 2 arranged on the ground and a trimming device 1 arranged in the retaining wall 2, and also includes a sedimentation tank 3, a mud pump 5, a separation tank 6 and a recovery device. There are many options for the retaining wall 2, such as: an annular wall built on the ground, the lower part of the retaining wall 2 is connected with a return pipe, and the other end of the return pipe extends to the bottom of the sedimentation tank 3. A mixer 4 is arranged in the sedimentation tank 3, the input end of the mud pump 5 is connected with the bottom of the sedimentation tank 3, and the output end is connected with the recovery device. There are many options for the recovery device, such as: a mortar mixing tank.

[0017] The separation tank 6 is a rotating body with a cylindrical upper portion and a conical lower portion, and the top of the separation tank 6 is sealed and the lower end is open. A vortex component is provided inside the separation tank 6, and spiral strips are evenly provided along the circumference on the inner side wall of the lower portion of the separation tank 6; the vortex component includes a drive shaft 8 rotatably installed in the separation tank 6, the separation tank 6 and the drive shaft 8 are concentrically arranged, a drive motor 7 is fixedly installed on the top of the separation tank 6, the drive motor 7 is transmission-connected to the drive shaft 8, a turbine 9 is mounted on the lower end of the drive shaft 8, and the rotation direction of the turbine 9 is opposite to the spiral direction of the spiral strip.

[0018] There are many ways to connect the drive motor 7 and the drive shaft 8. For example, the top end of the drive shaft 8 passes through the separation tank 6 and is fixedly connected to the output shaft of the drive motor 7 through a coupling. The spiral gear bar is arranged in a counterclockwise spiral. The drive motor 7 drives the turbine 9 to rotate clockwise, so that the water inside the separation tank 6 rotates clockwise to form a vortex. During the rotation of the water, under the action of centrifugal force, the dust particles in the water will rotate clockwise along the inner wall of the separation tank 6, and then move downward under the action of the spiral gear bar and gather at the bottom of the separation tank 6, thereby achieving the effect of separating impurities.

[0019] A connecting pipe 10 is horizontally arranged below the separation tank 6, and a connecting rod is concentrically arranged in the connecting pipe 10. Three pistons 14 are spaced apart on the connecting rod. The three pistons 14 divide the connecting pipe 10 into a first chamber, a second chamber, a third chamber and a fourth chamber. The piston 14 is made of rubber material, and the outer ring surface of the piston 14 is in close contact with the inner wall of the connecting pipe 10; the opening of the separation tank 6 is connected to the second chamber, and the tops of the first and third chambers are both provided with air inlet holes 21, and the lower parts are both connected with impurity discharge pipes 22, and the other end of the impurity discharge pipe 22 extends to the bottom of the sedimentation tank 3.

[0020] A reciprocating mechanism is provided at one end of the connecting pipe 10, and the output end of the reciprocating mechanism is drivingly connected to the piston 14 on the adjacent side. The input end of the water pump 11 is connected to the upper part of the sedimentation tank 3, and the output end is connected to the lower part of the separation tank 6; the input end of the water pump 11 is connected to a water pumping pipe 12, and the other end of the water pumping pipe 12 extends to the upper part of the sedimentation tank 3, and the output end of the water pump 11 is connected to a drain pipe 13, and the other end of the drain pipe 13 is connected to the lower part of the separation tank 6; a fixed plate is fixedly installed at the left end of the connecting pipe 10, and the reciprocating mechanism includes a transmission belt 20 and a motor 18 fixedly mounted on a fixed plate, further comprising a screw barrel 16 rotatably mounted on the fixed plate, the screw barrel 16 being concentrically arranged with the connecting pipe 10, the internal thread of the screw barrel 16 being sleeved with a connecting rod 15, the other end of the connecting rod 15 extending into the connecting pipe 10 and being fixedly connected to the piston 14 on the adjacent side, the outside of the screw barrel 16 and the output shaft of the motor 18 being respectively sleeved with a first pulley 17 and a second pulley 19, the first pulley 17 and the second pulley 19 being connected through a transmission belt 20.

[0021] When more dust particles accumulate in the second chamber, the motor 18 drives the screw barrel 16 to rotate through the belt drive. Since the piston 14 is made of rubber material and the outer ring surface of the piston 14 is in close contact with the inner wall of the connecting pipe 10, the friction between the piston 14 and the connecting pipe 10 is relatively large. Therefore, when the screw barrel 16 rotates, it can drive the connecting rod 15 to move axially to the left through the threaded connection until the left piston 14 and the middle piston 14 are respectively located on both sides of the impurity discharge pipe 22 on the first chamber. At this time, the opening of the separation tank 6 is located between the right piston 14 and the middle piston 14, and the dust particles in the left piston 14 and the middle piston 14 are discharged into the sedimentation tank 3 through the impurity discharge pipe 22, so that the separation operation and the impurity discharge operation are carried out simultaneously to achieve the continuity of water supply; a dust cover is provided on the cutting knife of the trimming device 1, and an atomizing nozzle is provided in the dust cover. The upper part of the separation tank 6 is connected with a water supply pipe, and the other end of the water supply pipe is connected with the atomizing nozzle.

[0022] When we use the device to trim the insulation board, the atomizing nozzle in the dust cover can spray water mist, which can cool the cutter and extend the working time of the cutter on the one hand, and on the other hand, it can reduce the dust generated by cutting to prevent the dust from drifting into the air and affecting the health of the workers; the water droplets mixed with dust are collected in the retaining wall 2, and then flow into the sedimentation tank 3 through the reflux pipe, and settle in the sedimentation tank 3. The water pump 11 extracts the upper layer of clean water and transports it to the separation tank 6. The driving motor 7 drives the turbine 9 to rotate clockwise, so that the water inside the separation tank 6 rotates clockwise to form a vortex, and the water During the rotation, under the action of centrifugal force, the dust particles in the water will rotate clockwise along the inner wall of the separation tank 6, and then move downward under the action of the spiral bar, and gather at the bottom of the separation tank 6, so as to further separate the impurities in the clean water, and the clean water is transported to the atomizing nozzle, and the separated impurities continue to flow back to the sedimentation tank 3; when there are many dust particles in the sedimentation tank 3, start the mixer 4, and after the mixer 4 fully mixes the water and dust particles in the sedimentation tank 3, start the mud pump 5, and use the mud pump 5 to transport the mixture of water and dust particles to the mortar mixing tank, so as to realize the recycling of resources.

[0023] Embodiment 2: Embodiment 2 is different from Embodiment 1 in that Figure 2 As shown, the screw barrel 16 is set away from the center of the connecting tube 10. When the screw barrel 16 rotates, under the action of friction, the screw barrel 16 will drive the connecting rod 15 to rotate synchronously. Since the axes of the connecting rod 15 and the piston 14 are not in a straight line, when the piston 14 rotates along the axis of the connecting rod 15, the outer annular surface of the piston 14 will squeeze the inner wall of the connecting tube 10, thereby increasing the friction between the connecting tube 10 and the piston 14 until it is greater than the friction between the connecting rod 15 and the screw barrel 16. At this time, the screw barrel 16 will drive the connecting rod 15 to move axially through the threaded connection. Example 2 is only used to illustrate a possible optimization method of the technical solution of the present invention and does not constitute a limitation to the claims.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
