Description

Technical Field

[0001] The invention belongs to the technical field of construction waste utilization, and in particular relates to a construction waste recycled micro-powder separation and preparation device. Background Art

[0002] Due to the acceleration of urbanization, the amount of construction waste is increasing. Traditional treatment methods such as landfill and incineration not only occupy a large amount of land resources, but also may cause environmental pollution. Therefore, it is particularly important to convert construction waste into reusable resources. Therefore, it is more efficient and less polluting to prepare construction waste into recycled micropowder. When processing recycled micropowder, it needs to be separated by a separation device, but the existing device has defects. For example, in the Chinese patent with the announcement number "CN 113814159A", a construction waste recycled micropowder separation and preparation device is disclosed, including a bracket, a body, a feed hopper, and a discharge hopper. The bottom surface of the body is welded to the top surface of the bracket, the bottom end of the feed hopper is installed on the top of the body near the right end, and the right end of the discharge hopper is tilted and fixed on the left side surface of the body. The feed hopper includes a shell, a pushing mechanism, and a filter plate. The pushing mechanism is respectively installed on the inner walls on the left and right sides of the shell, and the bottom surfaces of the left and right ends of the filter plate are against the upper surface of the pushing mechanism. The pushing mechanism includes a spring block, a frame, an active cavity, a push rod, a push plate, and a discharge port. The right side surface of the frame is connected to the left side surface of the spring block. The active cavity is recessed from top to bottom on the upper surface of the frame.

The discharge port passes through the bottom surface of the frame close to the left and right sides respectively, and is connected to the bottom of the active cavity. Although the device can realize the separation of fine powder, when the device is added, the powder is easily lifted up during the adding process, which not only increases the damage to the raw materials and the production cost, but also easily causes pollution to the surrounding environment. In addition, during the separation process, it relies on its own gravity for separation, so the separation efficiency is low. Summary of the invention

[0017] (3) After the present invention guides the powder to be transported into the inner cavity of the inner cylinder through the feed pipe, the inner cylinder is driven to rotate by the second motor, so that the powder is separated under the action of centrifugal force, avoiding the powder being separated only by its own gravity, thereby improving the separation efficiency of the powder.

[0018] (4) When the inner cylinder of the present invention separates the powder, a plurality of partitions are arranged inside the inner cylinder. After the powder is transported into the inner cylinder, the partitions receive the powder and cooperate with the notches on the partitions so that the powder can pass through each partition in turn, thereby preventing the powder from being discharged through the discharge pipe without being thoroughly processed. No secondary processing is required, thereby further improving the processing efficiency of the powder. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-Figure 9 As shown, the present invention provides the following technical solutions:

[0031] A construction waste recycled fine powder separation and preparation device comprises a shell member 1, a separator 3 for separating powder is arranged inside the shell member 1, and a feed member 2 is arranged on the shell member 1, a conveying channel for conveying powder along a preset path is formed inside the feed member 2, the discharge end of the conveying channel is above the separator 3, and the feed end of the conveying channel is above the shell member 1, the feed member 2 comprises a plurality of conical covers 24, the plurality of conical covers 24 are stacked up and down in sequence along the conveying channel, and the top of the conical cover 24 is open to form a conical cavity 25, and the bottom of the conical cover 24 forms a bottom hole 26, the bottom hole 26 is connected to the conical cavity 25, and the diameter of the bottom hole 26 is smaller than the diameter of the conical cavity 25.

[0032] Through the above technical solution, when personnel need to separate powder, they place the device at the required position, add powder to the inside of the feed piece 2, guide the powder through the conveying channel on the feed piece 2, and convey the powder to the separator 3 inside the shell 1 through the conveying channel. In the process of powder conveying, multiple conical covers 24 cooperate, and the bottom hole 26 cooperates with the conical cavity 25. In addition, in the present invention, since the diameter of the bottom hole 26 is smaller than the diameter of the conical cavity 25, the powder can be normally conveyed to the separator 3, and the powder can be prevented from being lifted up during the conveying process, and the powder can be prevented from accidentally leaking through the feeding end of the feed piece 2. When the powder enters the separator 3, the powder is separated by the separator 3, so that the larger powder is retained in the separator 3, and the smaller powder passes through the separator 3 and falls below the separator 3, thereby entering the shell 1, and completing the separation of the powder.

[0033] When the powder is added into the conveying channel of the feed member 2, in order to improve the conveying efficiency of the powder, Figure 1-Figure 3 , Figure 5-Figure 6 As shown, an auger 27 is rotatably connected between two adjacent conical covers 24 , a first connecting rod 28 is fixedly connected between the plurality of augers 27 , and the plurality of augers 27 are located inside the conveying passage.

[0034] In this embodiment, when the powder is inside the feed piece 2, the first connecting rod 28 rotates, thereby driving multiple augers 27 to rotate inside the feed piece 2, thereby driving the powder to move in the conveying channel, so that the powder can pass through the multiple conical covers 24 faster, so that the powder can be transported to the inside of the separator 3 faster, and the powder can be separated by the separator 3 faster, thereby improving the separation efficiency of the separator 3.

[0035] Specifically, in one embodiment, regarding the above-mentioned feed member 2, as Figure 1-Figure 3 , Figure 6 As shown, the feed member 2 includes a feed pipe 21 , a conveying channel is formed inside the feed pipe 21 , and a first motor 29 is fixedly connected to the outside of the feed pipe 21 , and an output end of the first motor 29 is connected to a first connecting rod 28 .

[0036] In this embodiment, when personnel need to process powder, they add powder to the inside of the feed pipe 21, guide the powder through the conveying channel on the feed pipe 21, and drive the first motor 29 to rotate the first connecting rod 28, and drive the auger 27 to rotate through the first connecting rod 28, and drive the powder to move in the conveying channel inside the feed pipe 21 through the auger 27, so that the powder passes through the multiple conical covers 24 in sequence, cooperates with the multiple conical covers 24, and passes through the bottom hole 26 and the conical cavity 25. Since the diameter of the bottom hole 26 is smaller than the diameter of the tapered cavity 25, the powder can be normally conveyed to the separator 3, and the powder can be prevented from being lifted up during the conveying process, and the powder can be prevented from accidentally leaking through the feeding end of the feeding pipe 21. When the powder is conveyed to the separator 3 inside the shell 1 through the conveying channel, the powder can be separated by the separator 3, so that the larger powder is retained in the separator 3, and the smaller powder passes through the separator 3 and falls below the separator 3, thereby entering the shell 1 and being discharged.

[0037] Furthermore, in the present invention, when personnel add powder, in order to improve the efficiency of adding powder, as Figure 1-Figure 3 , Figure 6 As shown, a feed end of the feed pipe 21 is fixedly connected to a material guide hopper 22 , and a material guide cavity 23 is formed inside the material guide hopper 22 .

[0038] In this embodiment, when personnel need to add powder, they add the powder into the guide cavity 23 inside the guide hopper 22, and the powder is guided by the guide cavity 23 to be transported to the inside of the feed pipe 21, so that the powder can be fed normally.

[0039] In addition, when personnel add powder to the guide chamber 23 on the guide hopper 22, in order to make the powder mixed more evenly, Figure 1-Figure 2 , Figure 6 As shown, one end of the first connecting rod 28 is fixedly connected to the second connecting rod 210 , and the circumference of the second connecting rod 210 is fixedly connected to the stirring rod 211 . Both the stirring rod 211 and the second connecting rod 210 are located inside the material guiding cavity 23 .

[0040] In this embodiment, when a person adds powder into the material guide chamber 23, the first motor 29 is operated, so that the first motor 29 drives the first connecting rod 28 to rotate, and the first connecting rod 28 drives the auger 27 and the second connecting rod 210 to rotate synchronously, and the second connecting rod 210 drives the stirring rod 211 to rotate, and the stirring rod 211 stirs the powder in the material guide chamber 23, so that the powder added to the material guide chamber 23 can be mixed more evenly, and the evenly mixed powder can enter the interior of the feed pipe 21 faster, thereby improving the efficiency of adding powder.

[0041] Specifically, in one embodiment, regarding the housing 1, Figure 1-Figure 5 As shown, the shell member 1 includes an outer shell 11, and a support rod 12 for supporting itself is fixedly connected to the outer side of the outer shell 11, one side of the outer shell 11 is open to form a discharge hole 13 for discharging powder, and one side of the outer shell 11 is also open to form a feed hole 15 connected to the feed pipe 21, and the feed hole 15 is above the discharge hole 13.

[0042] In this embodiment, when using the device, the shell 1 is placed at a position required by the personnel, the outer shell 11 is supported by the support rod 12, the powder is added to the guide cavity 23 inside the guide hopper 22, and the powder is guided by the guide cavity 23 so that the powder is transported to the inside of the feed pipe 21. When the personnel add the powder, the first motor 29 is operated, so that the first motor 29 drives the first connecting rod 28 to rotate, and the first connecting rod 28 drives the auger 27 and the second connecting rod 210 to rotate synchronously, and the second connecting rod 210 drives the stirring rod 211 to rotate, and the stirring rod 211 stirs the powder in the guide cavity 23, so that the powder added to the guide cavity 23 can be mixed more evenly, and the evenly mixed powder can enter the inside of the feed pipe 21 faster. After the powder enters the interior of the feed pipe 21, the auger 27 drives the powder to move in the conveying channel inside the feed pipe 21, so that the powder passes through multiple conical covers 24 in turn, cooperates with the multiple conical covers 24, and cooperates with the conical cavity 25 through the bottom hole 26. Since the diameter of the bottom hole 26 is smaller than the diameter of the conical cavity 25, the powder can be normally conveyed to the separator 3, and the powder is prevented from accidentally leaking from the feed end of the feed pipe 21 after being lifted up during the conveying process. After the powder is conveyed to the separator 3 inside the shell 1 through the conveying channel, the powder is separated by the separator 3, so that the larger powder is retained in the separator 3, and the smaller powder passes through the separator 3 and falls below the separator 3, thereby entering the interior of the shell 11 and being discharged through the discharge hole 13.

[0043] After the powder is separated by the separator 3, the powder that meets the requirements will be discharged through the surrounding surface of the separator 3. In order to improve the discharge efficiency of the powder that meets the requirements, Figure 1 , Figure 3-Figure 5 As shown, the bottom end of the inner part of the shell 11 is inclined to form a material guiding slope 16, and the horizontal height of the material guiding slope 16 on one side close to the discharge hole 13 is lower than the horizontal height on the other side.

[0044] In this embodiment, when the discharge hole 13 discharges the powder, the guide slope 16 cooperates to allow the powder to be discharged faster, thereby improving the powder discharge efficiency.

[0045] Specifically, in one embodiment, regarding the above-mentioned separator 3, as Figure 5 , Figure 8-Figure 9As shown, the separator 3 includes an inner cylinder 37, a circumferential surface of the inner cylinder 37 forms a side groove 38, and the top of the inner cylinder 37 is open to form an inner cavity 310, the side groove 38 is connected to the inner cavity 310, and the inside of the side groove 38 is fixedly connected with a baffle 39, and the bottom of the inner cylinder 37 is fixedly connected with a discharge pipe 14 connected to the inner cavity 310, and the bottom of the discharge pipe 14 extends to the bottom of the outer shell 11.

[0046] In this embodiment, when the feed pipe 21 discharges the powder, the powder is transported to the inner cavity 310 inside the inner cylinder 37, and the powder is filtered through the baffle 39, so that the larger powder is retained in the inner cavity 310, and the smaller powder passes through the baffle 39 and is discharged through the side groove 38. The smaller powder is transported to the inner bottom end of the outer shell 11, the larger powder is discharged through the discharge pipe 14, and the smaller powder is discharged through the discharge hole 13, thereby completing the separation of the powder.

[0047] When the powder to be separated enters the inner cavity 310, in order to further improve the separation efficiency of the powder, Figure 5 , Figure 8-Figure 9 As shown, a second motor 31 is fixedly connected to the top of the outer shell 11, and the output end of the second motor 31 is connected to a bottom rod 32. A plurality of partitions 33 are stacked up and down inside the inner cavity 310, and notches 34 are formed on the plurality of partitions 33. The plurality of notches 34 are staggered, and the bottom of the bottom rod 32 is fixedly connected to the top of the partition 33.

[0048] In this embodiment, after the powder is transported to the interior of the inner cylinder 37, the powder is blocked by a plurality of partitions 33, thereby extending the processing time of the powder in the inner cavity 310, and when the powder is in the inner cavity 310, the second motor 31 is operated to drive the inner cylinder 37 to rotate inside the outer shell 11, so that the powder in the inner cylinder 37 is separated under the action of centrifugal force, thereby improving the centrifugal efficiency of the powder, and through the cooperation of the notch groove 34 on the partition 33, the powder passes through the partition 33 and falls to the bottom of the inner cylinder 37, and finally the larger powder is discharged through the discharge pipe 14, thereby preventing the smaller powder from being discharged from the discharge pipe 14 together with the larger powder after being unprocessed.

[0049] Furthermore, in the present invention, after the feed pipe 21 discharges the powder, in order to facilitate the addition of the powder into the inner cavity 310, as shown in FIG. Figure 5 , Figure 7-Figure 9 As shown, a material guiding cover 35 is disposed inside the outer shell 11 . The material guiding cover 35 is located above the inner cylinder 37 , and a material discharge cavity 36 is formed on the material guiding cover 35 .

[0050] In this embodiment, after the feed pipe 21 discharges the powder, the powder falls into the material guide cover 35, and is guided by the discharge cavity 36 on the material guide cover 35, so that the powder can be easily transported to the inner cavity 310 in the inner cylinder 37, thereby facilitating the separation and processing of the powder.

[0051] 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.
