Description

Technical Field

[0001] This utility model belongs to the field of construction solid waste resource utilization technology, and specifically relates to a lightweight material separation device for recycled aggregates from construction waste. Background Technology

[0002] Among construction waste, renovation waste is the most difficult to utilize as a resource. Its composition is complex and varied, with a high content of lightweight materials (usually including impurities with low density such as plastics, wood, foam, and cardboard) and a low content of high-strength components. This results in recycled aggregates with low strength, poor density, and a high content of lightweight materials, which severely limits the scope of reuse of recycled aggregates.

[0003] Therefore, the separation of lightweight materials in recycled aggregates of construction waste is particularly important. Currently, water flotation is often used to separate lightweight materials in recycled aggregates of construction waste. However, when separating lightweight materials using water flotation, some paper, wood chips, plastics and gypsum in recycled aggregates of construction waste are difficult to float due to adhesion, resulting in poor separation effect. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a lightweight material separation device for recycled aggregates from construction waste, which can simply, quickly, and thoroughly separate lightweight materials from recycled aggregates from construction waste.

[0005] A lightweight material separation device for recycled aggregates from construction waste according to an embodiment of the present invention includes: a mixing drum, wherein a mixing chamber is provided inside the mixing drum, a limiting mechanism is provided on the mixing chamber, and a drain pipe communicating with the mixing chamber is provided at the lower part of the mixing drum; a mixing mechanism including a drive motor and a feeding impeller, wherein the feeding impeller is disposed in the mixing chamber and its position in the mixing chamber is lower than the limiting mechanism, and the drive motor can drive the feeding impeller to rotate; and a filter mechanism including a filter screen, a sleeve frame, and a filter screen control, wherein the filter screen is rotatably disposed at the bottom of the sleeve frame, and the filter screen can be controlled to rotate on the sleeve frame by the filter screen control, the sleeve frame can be inserted into the mixing drum, and the limiting mechanism can cooperate with the filter screen to limit its position.

[0006] According to an embodiment of this utility model, a lightweight material separation device for recycled aggregate from construction waste has at least the following technical effects: In use, the recycled aggregate from construction waste and water are first added to a mixing drum. Then, the drive motor is started to rotate the feeding impeller, which moves the material, causing the lightweight material adhering to the material to detach and float on the water surface. The filter screen is then controlled to rotate vertically via a filter screen control. A sleeve frame is then inserted into the mixing drum, and the filter screen is controlled to rotate horizontally until it engages with a limiting mechanism for positioning, placing the filter screen between the lightweight material and the bottom layer of material. The drive motor is then turned off, and the drain pipe is opened to drain the water from the mixing drum, allowing the lightweight material to fall onto the filter screen. The sleeve frame is then removed, allowing the lightweight material to be removed along with the filter screen, thus achieving the separation of the lightweight material from the recycled aggregate from construction waste.

[0007] According to some embodiments of this utility model, the limiting mechanism includes two semi-circular limiting seats arranged opposite each other on the inner wall of the stirring chamber. The limiting seats are made of elastic material and have annular limiting grooves. Each limiting seat includes an upper baffle and a lower baffle. The length of the upper baffle of one limiting seat is greater than the length of the lower baffle, and the length of the upper baffle of the other limiting seat is less than the length of the lower baffle. The filter screen can rotate into the limiting grooves of the two limiting seats and cooperate with the limiting seats to achieve limiting and sealing of the edge of the filter screen. When using this construction waste recycled aggregate lightweight material separation device, with the filter screen in a vertical position, the sleeve frame is inserted into the mixing cylinder to ensure the filter screen is at a suitable depth. Then, the filter screen is rotated by the filter screen control, causing both sides of the filter screen to enter the limiting groove from the shorter baffles of the two limiting seats. Simultaneously, the elastic upper and lower baffles of the two limiting seats achieve limiting and sealing of the filter screen edges. When the sleeve frame needs to be removed, simply control the filter screen to rotate slightly in the opposite direction by the filter screen control, causing both sides of the filter screen to disengage from the shorter baffles of the two limiting seats and thus escape from the limiting groove. Then, the sleeve frame is removed upwards. At this time, the filter screen is in a slightly tilted state. During the removal of the sleeve frame, the lightweight material on the filter screen will not fall off.

[0008] According to some embodiments of the present invention, the sleeve frame includes a circular upper frame and two columnar side supports, the upper ends of the two side supports are fixedly connected to the upper frame, and the filter screen is rotatably connected to the lower ends of the two side supports.

[0009] According to some embodiments of this utility model, the filter control includes a support rod and a filter pull wire. The support rod is disposed on the upper frame, and a rotating shaft is provided on the support rod. The two ends of the filter pull wire are respectively connected to the two ends of the filter. The middle part of the filter pull wire is wound around the rotating shaft. By rotating the rotating shaft, the filter pull wire can pull the filter to rotate at the lower ends of the two side supports. The rotation of the filter can be controlled by rotating the rotating shaft.

[0010] According to some embodiments of this utility model, two sleeves are provided at the lower ends of the two side supports, and two rods are provided opposite to each other on the outer side of the filter screen. The two rods are respectively engaged with the two sleeves. By engaging the two rods with the two sleeves, the filter screen can be rotatably installed at the lower ends of the side supports. A quick-release structure is provided between the filter screen and the rods, which can realize the quick installation and removal of the filter screen.

[0011] According to some embodiments of this utility model, the drive motor is a variable frequency motor, and the mixing drum is equipped with a speed adjustment knob for controlling the rotation of the drive motor. The rotation speed of the drive motor can be controlled by the speed adjustment knob, thereby controlling the speed of the feeding impeller to adapt to the separation of lightweight materials in recycled construction waste aggregates of different particle sizes.

[0012] According to some embodiments of this utility model, the mixing drum is further provided with a flushing pipe. One end of the flushing pipe is provided with a water inlet, and the other end of the flushing pipe is a flushing port. The flushing port is located inside the mixing chamber and can cooperate with the wall of the mixing chamber to flush water. Water can be injected into the water inlet to flush the wall of the mixing chamber. Therefore, when using the equipment, after draining the water from the drain pipe and then injecting water through the water inlet, the light substances adhering to the wall of the mixing chamber can be flushed onto the filter screen, achieving a better separation effect.

[0013] According to some embodiments of this utility model, the inner diameter of the stirring chamber gradually decreases from top to bottom, and the flushing pipe is spirally arranged along the outer wall of the mixing cylinder. This arrangement allows water to flow into the mixing cylinder along the spirally downward-facing flushing pipe after being injected from the water inlet. The water then flows obliquely out from the flushing port inside the stirring chamber and spirals down the wall of the stirring chamber, forming a vortex. Combined with the upper-wide, lower-narrowing structure of the stirring chamber, this achieves a better flushing effect on light substances adhering to the walls of the stirring chamber. According to some embodiments of this utility model, an outer cylinder is also included, located outside the mixing cylinder. A sandwich is formed between the outer cylinder and the mixing cylinder, and the flushing pipe is located within this sandwich, with one end of the flushing pipe's water inlet penetrating and installed on the outer cylinder. The outer cylinder facilitates the installation of the flushing pipe.

[0014] According to some embodiments of this utility model, both the mixing cylinder and the outer cylinder are made of transparent material, and the outer cylinder has scale lines along the height direction. The water level can be determined by the scale lines.

[0015] According to some embodiments of this utility model, the filter screen is made of stainless steel. Attached Figure Description

[0029] The following is for reference. Figures 1 to 3 This invention describes a lightweight material separation device for recycled aggregates from construction waste, according to an embodiment of the present invention.

[0030] like Figure 1 and Figure 2As shown, a lightweight material separation device for recycled aggregates from construction waste according to an embodiment of the present invention includes: a mixing drum 100, a mixing mechanism, and a filter screen mechanism; a mixing chamber 101 is provided inside the mixing drum 100, a limit mechanism is provided on the mixing chamber 101, and a drain pipe 102 communicating with the mixing chamber 101 is provided at the lower part of the mixing drum 100; the mixing mechanism includes a drive motor 201 and a material-pushing impeller 202, the material-pushing impeller 202 is disposed inside the mixing chamber 101 and the material-pushing impeller... The position of 202 in the mixing chamber 101 is lower than the limiting mechanism, and the drive motor 201 can drive the feeding impeller 202 to rotate; the filter mechanism includes a filter screen 301, a sleeve frame 302 and a filter screen control 303. The filter screen 301 is rotatably set at the bottom of the sleeve frame 302, and the filter screen 301 can be controlled to rotate on the sleeve frame 302 through the filter screen control 303. The sleeve frame 302 can be inserted into the mixing cylinder 100 and the limiting mechanism can cooperate with the filter screen 301 to limit it. The drive motor 201 is located at the lower part of the mixing drum 100. The material-pushing impeller 202 is a hook-shaped impeller. A drain valve 103 is provided at the end of the drain pipe 102. A water inlet valve 111 is provided at the end of the flushing pipe 106 near the water inlet 107. When using this construction waste recycled aggregate lightweight material separation device, the construction waste recycled aggregate and water are first added to the mixing drum 100. Then, the drive motor 201 is started to make the material-pushing impeller 202 rotate. The material-pushing impeller 202 pushes the material, causing the lightweight material adhering to the material to detach from the material and float on the water surface. Then, it passes through the filter screen control 30. 3. Control the filter screen 301 to rotate to a vertical position, then insert the sleeve frame 302 into the mixing drum 100, and then control the filter screen to rotate to a horizontal position through the filter screen control 303 until it cooperates with the limiting mechanism to limit and fix it, so that the filter screen 301 is between the light material and the bottom material. Then turn off the drive motor 201, open the drain pipe 102 to drain the water in the mixing drum 100, and the light material falls onto the filter screen 301. Then remove the sleeve frame 302 so that the light material is removed together with the filter screen 301, thereby realizing the separation of light material and recycled aggregate from construction waste.

[0031] like Figure 3 and Figure 4As shown, in some specific embodiments of this utility model, the limiting mechanism includes two semi-circular limiting seats 104 arranged opposite to each other on the inner wall of the stirring chamber 101. The limiting seats 104 are made of elastic material and are provided with an annular limiting groove 104a. The limiting seat 104 includes an upper baffle 104b and a lower baffle 104c. The length of the upper baffle 104b of one limiting seat 104 is greater than the length of the lower baffle 104c, and the length of the upper baffle 104b of the other limiting seat 104 is less than the length of the lower baffle 104c. The filter screen 301 can rotate into the limiting groove 104a of the two limiting seats 104 and cooperate with the limiting seats 104 to achieve limiting and sealing of the edge of the filter screen 301. The filter screen 301 is circular. When using this construction waste recycled aggregate lightweight material separation device, with the filter screen 301 in a vertical position, the sleeve frame 302 is inserted into the mixing cylinder 100 to bring the filter screen 301 to a suitable depth. Then, the filter screen 301 is rotated via the filter screen control 303, causing both sides of the filter screen 301 to enter the limiting groove 104a from the shorter flanges of the two limiting seats 104. Simultaneously, the upper flange 104b and lower flange 104b of the two limiting seats 104 elastically engage with the filter screen. Under the action of c, the edge of the filter screen 301 is limited and sealed. When the sleeve frame 302 is to be removed, the filter screen 301 is only controlled to rotate slightly in the opposite direction by the filter screen control 303, so that the two sides of the filter screen 301 are respectively dislodged from the shorter side of the two limiting seats 104 and thus separated from the limiting groove 104a. Then the sleeve frame 302 is taken out upward. At this time, the filter screen 301 is in a slightly tilted state. During the process of taking out the sleeve frame 302, the light material on the filter screen 301 will not fall off the filter screen 301.

[0032] In some specific embodiments of this utility model, the sleeve frame 302 includes a circular upper frame 302a and two columnar side supports 302b. The upper ends of the two side supports 302b are fixedly connected to the upper frame 302a, and the filter screen 301 is rotatably connected to the lower ends of the two side supports 302b.

[0033] In some specific embodiments of this utility model, the filter control 303 includes a support rod 303a and a filter pull wire 303b. The support rod 303a is mounted on the upper frame 302a, and a rotating shaft 304 is mounted on the support rod 303a. Both ends of the filter pull wire 303b are connected to both ends of the filter 301, and the middle part of the filter pull wire 303b is wound around the rotating shaft 304. Rotating the rotating shaft 304 causes the filter pull wire 303b to pull the filter 301 to rotate at the lower ends of the side supports 302b. The rotation of the filter 301 can be controlled by rotating the rotating shaft 304.

[0034] In some specific embodiments of this utility model, two sleeves 305 are provided at the lower ends of the side supports 302b, and two rods 306 are provided opposite to each other on the outer side of the filter screen 301. The two rods 306 are respectively engaged with the two sleeves 305. By engaging the two rods 306 with the two sleeves 305, the filter screen 301 can be rotatably installed at the lower ends of the side supports 302b. A quick-release structure is provided between the filter screen 301 and the rods 306, which can realize the quick installation and removal of the filter screen 301.

[0035] In some specific embodiments of this utility model, the drive motor 201 is a variable frequency motor, and the mixing drum 100 is provided with a speed adjustment knob 105 for controlling the rotation of the drive motor 201. The rotation speed of the drive motor 201 can be controlled by the speed adjustment knob 105, thereby controlling the speed of the feeding impeller 202 to adapt to the separation of light materials in recycled aggregates of construction waste of different particle sizes.

[0036] In some specific embodiments of this utility model, the mixing drum 100 is also provided with a flushing pipe 106. One end of the flushing pipe 106 is provided with a water inlet 107, and the other end of the flushing pipe 106 is a flushing port (not shown in the figure). The flushing port is located inside the mixing chamber 101 and can cooperate with the wall of the mixing chamber 101 to flush water. Water can be injected into the water inlet 107 to flush the wall of the mixing chamber 101. Thus, when using the equipment, after opening the drain pipe 102 to drain water, water can be injected into the water inlet 107 to flush the light substances attached to the wall of the mixing chamber 101 onto the filter screen 301, thereby achieving a better separation effect.

[0037] In some specific embodiments of this utility model, the inner diameter of the stirring chamber 101 gradually decreases from top to bottom, and the flushing pipe 106 is spirally arranged around the outer wall of the mixing cylinder 100. This arrangement allows water to flow into the mixing cylinder 100 along the spirally downward flushing pipe 106 after being injected from the water inlet 107. After being obliquely ejected from the flushing port inside the stirring chamber 101, the water flows down the wall of the stirring chamber 101 in a spiral shape, forming a vortex. Combined with the structure of the stirring chamber 101, which is wider at the top and narrower at the bottom, this achieves a better rinsing effect on light substances adhering to the wall of the stirring chamber 101.

[0038] In some specific embodiments of this utility model, an outer cylinder 108 is further provided outside the mixing cylinder 100, and a sandwich 109 is formed between the outer cylinder 108 and the mixing cylinder 100. The flushing pipe 106 is provided inside the sandwich 109, and one end of the water inlet 107 of the flushing pipe 106 is installed through the outer cylinder 108. The outer cylinder 108 facilitates the installation of the flushing pipe 106.

[0039] In some specific embodiments of this utility model, both the mixing cylinder 100 and the outer cylinder 108 are made of transparent material, and the outer cylinder 108 has a scale line 110 along the height direction. The water level can be determined by the scale line 110.

[0040] In some specific embodiments of this utility model, the filter screen 301 is made of stainless steel.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
