Description

Technical Field

[0001] This utility model relates to the field of batching device technology, specifically to a batching device for renewable concrete. Background Technology

[0002] Recyclable concrete is a building material that uses recycled raw materials to reduce its environmental impact. The raw materials it typically uses include recycled lightweight aggregates and fly ash.

[0003] Chinese patent CN219855293U discloses a batching device for renewable concrete, used to mix renewable concrete raw materials.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: In actual use, due to the presence of solid block particles in the renewable concrete raw materials, the mixing components used in the above-mentioned devices may get stuck during mixing, which in turn leads to a decrease in processing efficiency during the mixing process.

[0005] This invention proposes a batching device for renewable concrete to solve the problem. Summary of the Invention

[0006] The purpose of this invention is to enable the grinding and extrusion structures inside the device to crush lumpy impurities in the raw materials during the mixing process, thereby ensuring that there is no risk of jamming inside the device and overcoming the problems mentioned in the background art.

[0007] Based on the above technical concept, the technical solution adopted by this utility model is as follows: A batching device for renewable concrete includes a base and feet connected to its bottom, an outer shell connected to the top of the base, a cover plate connected to the top of the outer shell, a feed hopper connected through the top of the cover plate, a rotating component connected to the bottom of the base for mixing and stirring renewable concrete, and a discharge component connected through the top of the base.

[0008] Further defining the above technical solution, the rotating component includes a motor bracket connected to the bottom of the base, the motor bracket is connected to a rotating motor, the top output end of the rotating motor is connected to a rotating shaft, and the rotating shaft passes through the center of the base. By placing the motor at the bottom, the center of gravity of the device can be lowered, thereby reducing the risk of the device tipping over, and at the same time avoiding the motor from obstructing the feeding structure.

[0009] Further defining the above technical solution, a connector is connected to the end of the rotating shaft away from the rotating motor. A pressing roller is symmetrically connected to the side of the connector, and a conical grinding part is connected to the top of the connector. The connector drives the symmetrical pressing roller to rotate, thereby achieving the effect of extruding and processing the mixed powder raw materials, which makes the final powder product more delicate and the mixing effect more thorough.

[0010] Further defining the above technical solution, a guide ring is connected to the inner arc surface of the outer shell. The inner arc surface of the guide ring is conical, and the conical slope of the inner arc surface of the guide ring is inclined towards the conical grinding part. There is a gap between the inner arc surface of the guide ring and the outer arc surface of the conical grinding part. By controlling the size of the gap between the guide ring and the conical grinding part, the particle size of the material output from the conical grinding part can be controlled. Only raw materials ground to a particle size smaller than the gap will fall into the pressing roller area, thereby realizing the first layer of grinding and screening of this device and avoiding damage to the pressing roller structure by excessively large blocky impurities.

[0011] Further defining the above technical solution, the top of the base is provided with several anti-slip grooves distributed in a circular pattern, and the outer arc surface of the pressing roller is provided with several extrusion protrusions distributed in a circular pattern at equal intervals. The extrusion protrusions contact the anti-slip grooves. The combination of the extrusion protrusions and the anti-slip grooves can improve the stability of the device in crushing raw materials, increase the surface roughness of the pressing roller, and improve the processing stability of the device.

[0012] Further defining the above technical solution, the feeding component includes a feeding channel disposed on the top of the base, a limiting groove provided on the inner arc side of the feeding channel, a screening screen provided inside the feeding channel, a limiting protrusion provided on the outer arc surface of the screening screen, and the limiting protrusion located in the limiting groove. The screening screen can achieve the effect of controlling the particle size of the discharged raw material, and different particle sizes can be achieved by changing the screening screen with different mesh sizes.

[0013] Further defining the above technical solution, the connecting member is inclinedly connected to a connecting bracket on one side perpendicular to the pressing roller, and a scraper is connected to the side of the connecting bracket. The bottom of the scraper contacts the top of the base. The combination of the connecting bracket and the scraper can scoop up the powdery material on the top of the base, thereby preventing the powdery material from adhering to the surface of the base for a long time.

[0014] Further defining the above technical solution, the outer arc surface of the scraper and the outer arc surface of the conical grinding part are provided with a wear-resistant layer, and the outer arc surface of the screening screen is provided with a sealing element. The sealing element contacts and presses against the inner arc surface of the feeding channel. The structure of the sealing element can prevent powder raw materials that do not conform to the particle size of the screening screen from leaking out from the gap between the feeding channel and the edge of the screening screen, thus ensuring the accuracy of the output of this device.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Easy to connect: The combination of the top feeding hopper and the bottom discharging structure of this device makes it easy to connect and integrate with upstream and downstream equipment, reducing the difficulty of combining and using this device. 2. To avoid jamming, this device uses a combination of grinding and rolling processes, which avoids the problem of blocky raw materials causing jamming in the transmission structure inside the device. 3. Accurate discharge: The structure of the screening mesh of this device can achieve the effect of constraining the particle size of the discharged powder raw materials, thereby ensuring the accuracy of the discharge.

[0019] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0020] Example 1: This example provides a batching device for renewable concrete, such as... Figures 1-4As shown, the base 1 and its bottom are connected to the foot 2, the top of the base 1 is connected to the outer shell 3, the top of the outer shell 3 is connected to the cover plate 4, the top of the cover plate 4 is connected to the feed hopper 5, the bottom of the base 1 is connected to the rotating part 6, which is used to mix and process the renewable concrete, and the top of the base 1 is connected to the discharge part 7.

[0021] The rotating component 6 includes a motor bracket 601 connected to the bottom of the base 1, a rotating motor 602 connected to the motor bracket 601, and a rotating shaft 603 connected to the top output end of the rotating motor 602, which passes through the center of the base 1.

[0022] A connector 604 is connected to the end of the rotating shaft 603 away from the rotating motor 602. A pressing roller 607 is symmetrically rotatably connected to the side of the connector 604, and a conical grinding part 605 is connected to the top of the connector 604.

[0023] A guide ring 606 is connected to the inner arc surface of the outer shell 3. The inner arc surface of the guide ring 606 is conical. The conical slope of the inner arc surface of the guide ring 606 is inclined towards the conical grinding part 605. There is a gap between the inner arc surface of the guide ring 606 and the outer arc surface of the conical grinding part 605.

[0024] The top of the base 1 is provided with several anti-slip grooves 609 distributed in a circular pattern, and several extrusion protrusions 608 are distributed in a circular pattern at equal intervals on the outer arc surface of the pressure roller 607, and the extrusion protrusions 608 are in contact with the anti-slip grooves 609.

[0025] The feeding component 7 includes a feeding channel 701 set on the top of the base 1. The inner arc side of the feeding channel 701 is provided with a limiting groove 702. The feeding channel 701 is provided with a screening screen 703 inside. The outer arc surface of the screening screen 703 is provided with a limiting protrusion. The limiting protrusion is located in the limiting groove 702.

[0026] The specific working principle is as follows: This device can crush and compress any solid blocky impurities that may exist in the raw materials during the mixing and processing of renewable concrete raw materials, thereby avoiding problems such as jamming of the mixing components due to blocky impurities, which may lead to breakage of the rotating transmission structure, and improving the processing stability of this device.

[0027] Example 2: This example provides a batching device for renewable concrete, such as... Figures 1-4 As shown, the connector 604 is inclinedly connected to the side of the pressing roller 607 with a connecting bracket 704, and a scraper 705 is connected to the side of the connecting bracket 704. The bottom of the scraper 705 is in contact with the top of the base 1.

[0028] The outer arc surface of scraper 705 and the outer arc surface of conical grinding part 605 are provided with wear-resistant layers, and the outer arc surface of screen 703 is provided with a sealing element. The sealing element contacts and is squeezed with the inner arc surface of discharge groove 701.

[0029] The specific working principle is as follows: This device can achieve the mixing and processing effect of renewable concrete raw materials. When the device is in use, the renewable concrete raw materials are poured into the shell 3 from the feed hopper 5. At this time, under the action of the guide ring 606, the falling renewable concrete raw materials are guided to the direction of the conical grinding part 605. At this time, the bottom rotating motor 602 is started, and the rotating motor 602 drives the rotating shaft 603 to rotate, thereby achieving the horizontal rotation effect of the conical grinding part 605. During the rotation of the conical grinding part 605 relative to the guide ring 606, the renewable concrete raw materials with a particle size larger than the gap between the conical grinding part 605 and the guide ring 606 are stuck in the gap. The renewable concrete raw materials smaller than the gap width fall to the pressing roller 607. The renewable concrete raw materials stuck in the gap are squeezed during the rotation of the conical grinding part 605, which leads to the crushing of the renewable concrete raw materials. With the crushing and grinding of the renewable concrete raw materials, the particle size of all renewable concrete raw materials is eventually smaller than the gap and finally falls into the area of ​​the pressing roller 607 below.

[0030] When the renewable concrete raw material enters the area of ​​the pressing roller 607, the connector 604 drives the two pressing rollers 607 to revolve. During the revolve of the pressing rollers 607, the renewable concrete raw material is located between the extrusion protrusion 608 and the anti-slip groove 609, which makes the renewable concrete raw material repeatedly crushed, further reducing the particle size of the renewable concrete raw material, and also making the renewable concrete raw material powder more fully mixed.

[0031] During the revolution of the pressing roller 607, the scraper 705 also revolves synchronously. The scraper 705 can scoop up the compressed powder from the top of the base 1, thereby ensuring that the powder returns to a loose state and is then compressed again, thus avoiding powder caking caused by continuous long-term compression.

[0032] When the particle size of the renewable concrete raw material powder is smaller than the mesh diameter of the 703 screen, the renewable concrete raw material can fall from the 703 screen, thus achieving the discharge effect of this device.

[0033] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
