Technical Field
[0001] This utility model relates to the field of construction waste treatment, and more specifically, to a vibrating screening device for pre-treatment of construction waste. Background Technology
[0002] With the rapid development of the construction industry, the problem of construction waste disposal has become increasingly prominent. In the process of construction waste disposal, construction waste is often classified, dismantled, reprocessed, and recycled.
[0003] A search revealed that Chinese patent CN222607208U discloses "a vibrating multi-stage solid waste pretreatment screening device, comprising a housing, wherein an iron removal chamber, a coarse material chamber, and a fine material chamber are arranged sequentially from top to bottom within the housing; a vibrating baffle is provided between the iron removal chamber and the coarse material chamber, and a material leakage port is provided in the middle of the baffle; a liftable iron suction mechanism is mounted above the iron removal chamber; and a screening mechanism is provided between the iron removal chamber and the coarse material chamber, the screening mechanism including a vibrating filter plate." One end of the filter plate is equipped with a scraping assembly for discharging material from the coarse material chamber, and the other end is equipped with a slag discharge pipe. The bottom of the fine material chamber is equipped with a discharge pipe. This utility model, through its spatial vertical distribution structure of the iron removal chamber, coarse material chamber, and fine material chamber, completes sorting at each stage while occupying little space. It can also directly extract iron from the waste. To ensure rapid and efficient iron removal, large pieces of waste can be scraped out for collection, making screening convenient, saving manpower, and greatly improving the processing and screening progress. However, the following drawbacks still exist:
[0004] (1) The inclination angle of the filter plate in the screening mechanism of the device is fixed. In actual construction waste treatment, different materials have different characteristics. For construction waste with poor flowability and fine particles, a larger inclination angle is required to speed up the movement speed on the screen. Since the inclination angle of the filter plate is fixed, the screening efficiency is low.
[0005] (2) The feeding method of this device lacks an effective adjustment mechanism, which can easily lead to excessive feeding causing blockage of the screening box, or insufficient feeding affecting screening efficiency, which is not conducive to the stable and efficient operation of screening.
[0006] Therefore, we have made improvements to this by proposing a vibrating screening device for the pretreatment of construction waste. Utility Model Content
[0007] The purpose of this utility model is to address the problems of inconvenient adjustment of screening inclination, difficulty in adapting to different material characteristics, imperfect feeding adjustment function, and impact on the stability of screening operations.
[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0009] A vibrating screening device for pre-processing construction waste is proposed to improve the above-mentioned problems.
[0010] The specific details of this utility model are as follows:
[0011] The device includes a frame, one side of which is equipped with an adjustment device for flexibly adjusting the tilt angle of the screening device to adapt to different material characteristics and screening requirements. The other side of the adjustment device is equipped with a feeding component for stably and evenly conveying construction waste to the screening area.
[0012] The adjusting device includes a support frame hinged to one side of the frame. Two sets of arc-shaped strips are symmetrically bolted to the inner side of the frame. The side wall of the support frame is bolted to the other end of the two sets of arc-shaped strips. Multiple sets of threaded holes are opened on the arc-shaped strips. A screening frame is provided above the support frame. A screening box is bolted to the top of the screening frame. A vibration motor is fixedly installed on the outside of the screening box. A screen is bolted to the inner wall of the screening box.
[0013] As a preferred technical solution of this utility model, the feeding assembly includes a feeding hopper hinged to the top of the screening box, two sets of arc-shaped plates symmetrically bolted to the top of the screening box, the other ends of the two sets of arc-shaped plates being fixedly connected to the feeding hopper by bolts, a rectangular groove being provided at the bottom of the feeding hopper, and a baffle being bolted to the bottom of the feeding hopper, the baffle being located at the bottom of the rectangular groove.
[0014] As a preferred technical solution of this utility model, four sets of connecting parts are bolted to the top of the support frame and the bottom of the screening frame, and buffer springs are bolted to each of the four sets of connecting parts.
[0015] As a preferred technical solution of this utility model, a feeding hopper is bolted to the top of the frame, and a rectangular plate is bolted to the bottom of the screening box. The rectangular plate is located below the feeding hopper and the screen, and above the feeding hopper.
[0016] As a preferred technical solution of this utility model, a guide plate is bolted to one side of the support frame, and the guide plate is located on one side of the screen.
[0017] As a preferred technical solution of this utility model, four sets of anti-slip pads are fixedly connected to the bottom of the frame, and the material of the four sets of anti-slip pads is rubber.
[0018] As a preferred technical solution of this utility model, a control board is bolted to one side of the frame, and the control board is electrically connected to the vibration motor.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In the solution of this utility model:
[0021] 1. Through the adjustable device, the operator can change the fixed connection between the support frame and the threaded holes at different positions of the two sets of arc strips during use. This will cause the support frame to rotate around the hinge point with the frame. The screening frame set above the support frame will change with the change of the tilt angle of the support frame. The high-frequency vibration generated by the vibrating motor can make the screening box and screen vibrate continuously to screen the material on the screen. For construction waste with poor flowability and fine particles, appropriately increasing the tilt angle can speed up the movement speed of the material on the screen and improve screening efficiency. For materials with good flowability and larger particles, decreasing the tilt angle can make the material stay on the screen for a longer time, ensuring full screening and improving screening quality. It is flexible to adjust and easy to use.
[0022] 2. With the feeding assembly in place, when the tilt angle of the feeding hopper needs to be adjusted, the operator only needs to loosen the bolts, rotate the feeding hopper around the hinge point to a suitable angle, and then tighten the bolts to fix the tilt angle of the feeding hopper. This changes the angle at which construction waste enters the screening box. When the feeding rate needs to be increased, the operator can move the baffle appropriately to increase the effective opening area of the rectangular trough, allowing more construction waste to enter the screening box. Conversely, when the feeding rate needs to be reduced, the baffle is moved in the opposite direction to reduce the opening area of the rectangular trough, thereby controlling the flow rate of construction waste entering the screening box. This allows for the adjustment of the feeding rate, ensuring stable and efficient screening operations and extending the service life of the equipment. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0031] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] like Figure 1 As shown, this embodiment proposes a vibrating screening device for pretreatment of construction waste, including a frame 1. One side of the frame 1 is provided with an adjustment device 2 for flexibly adjusting the tilt angle of the screening device to adapt to different material characteristics and screening requirements. One side of the adjustment device 2 is provided with a feeding component 3 for stably and uniformly conveying construction waste to the screening area.
[0035] like Figure 3 and Figure 4As shown, the adjusting device 2 includes a support frame 201 hinged to one side of the frame 1. Two sets of arc-shaped strips 202 are symmetrically bolted to the inner side of the frame 1. The side wall of the support frame 201 is bolted to the other end of the two sets of arc-shaped strips 202. Multiple sets of threaded holes are opened on the arc-shaped strips 202. A screening frame 203 is provided above the support frame 201. The angle of the screening frame 203 is changed by changing the fixed connection between the support frame 201 and the threaded holes at different positions of the two sets of arc-shaped strips 202. A screening box 204 is bolted to the top of the screening frame 203. A vibration motor 205 is fixedly installed on the outer side of the screening box 204. A screen 206 is bolted to the inner wall of the screening box 204. In use, the operator can change the fixed connection between the support frame 201 and the threaded holes at different positions of the two sets of arc-shaped bars 202, which will cause the support frame 201 to rotate around the hinge point with the frame 1. The screening frame 203 set above the support frame 201 will change with the change of the tilt angle of the support frame 201. The high-frequency vibration generated by the vibration motor 205 can make the screening box 204 and the screen 206 vibrate continuously, screening the material on the screen 206. For construction waste with poor flowability and fine particles, appropriately increasing the tilt angle can speed up the movement speed of the material on the screen 206 and improve screening efficiency. For materials with good flowability and larger particles, decreasing the tilt angle can make the material stay on the screen 206 for a longer time, ensuring full screening, improving screening quality, and making it flexible and easy to use.
[0036] like Figure 4 and Figure 5 As shown, the feeding assembly 3 includes a feeding hopper 301 hinged to the top of the screening box 204, two sets of arc plates 302 symmetrically bolted to the top of the screening box 204, and the other ends of the two sets of arc plates 302 are fixedly connected to the feeding hopper 301 by bolts. A rectangular groove is provided at the bottom of the feeding hopper 301, and a baffle 303 is bolted to the bottom of the feeding hopper 301. The baffle 303 is located at the bottom of the rectangular groove. When the tilt angle of the feed hopper 301 needs to be adjusted, the operator only needs to loosen the bolts, rotate the feed hopper 301 around the hinge point to a suitable angle, and then tighten the bolts to fix the tilt angle of the feed hopper 301, thereby changing the feeding angle of the construction waste into the screening box 204. When it is necessary to increase the feed rate, the operator can move the baffle 303 appropriately to increase the effective opening area of the rectangular trough, so that more construction waste can enter the screening box 204. Conversely, when it is necessary to reduce the feed rate, the baffle 303 is moved in the opposite direction to reduce the opening area of the rectangular trough, thereby controlling the flow rate of construction waste entering the screening box 204, realizing the adjustment of the feed rate, ensuring the stable and efficient screening operation, and extending the service life of the equipment.
[0037] like Figure 2 and Figure 4As shown, four sets of connectors 4 are bolted to the top of the support frame 201 and the bottom of the screening frame 203, and each of the four sets of connectors 4 is bolted with a buffer spring 5. When the vibrating motor 205 drives the screening box 204 to vibrate, the screening frame 203 will shake violently up and down, as well as back and forth and left and right. During this process, the buffer spring 5 will play its elastic role, absorbing and dissipating the energy generated by the vibration of the screening frame 203, reducing the propagation of vibration to the surrounding environment, and thus effectively reducing the noise generated during equipment operation.
[0038] like Figure 2 As shown, a hopper 6 is bolted to the top of the frame 1, and a rectangular plate 7 is bolted to the bottom of the screening box 204. The rectangular plate 7 is located below the feed hopper 301 and the screen 206, and above the hopper 6. Small particles of material screened by the screen 206 will fall into the hopper 6. The rectangular plate 7 can be used to guide the screened material into the hopper 6.
[0039] like Figure 1 and Figure 3 As shown, a guide plate 8 is bolted to one side of the support frame 201, and the guide plate 8 is located on one side of the screen 206. Large particles of material after being screened by the screen 206 will flow along the screen 206 to the guide plate 8. The operator can place a container under the guide plate 8 to collect the large particles of material.
[0040] like Figure 1 As shown, four sets of anti-slip pads 9 are fixedly connected to the bottom of the frame 1. The four sets of anti-slip pads 9 are made of rubber. During equipment operation, the four sets of anti-slip pads 9 can increase the friction between the device and the ground, ensuring that the equipment maintains a stable position during operation and guaranteeing the normal progress of screening operations.
[0041] like Figure 3 As shown, a control board 10 is bolted to one side of the frame 1, and the control board 10 is electrically connected to the vibratory motor 205. The operator can control the start, stop, speed adjustment, and frequency adjustment of the vibratory motor 205 by simply operating the buttons on the control board 10, which is convenient to use.
[0042] Specifically, when using this vibrating screening device for pre-treatment of construction waste: (e.g.) Figure 4 and Figure 5As shown, the operator only needs to loosen the bolts, rotate the feed hopper 301 around the hinge point to a suitable angle, and then tighten the bolts to fix the tilt angle of the feed hopper 301, thereby changing the feeding angle of the construction waste into the screening box 204. When it is necessary to increase the feed rate, the operator can appropriately move the baffle 303 to increase the effective opening area of the rectangular trough, allowing more construction waste to enter the screening box 204. Conversely, when it is necessary to decrease the feed rate, the baffle 303 is moved in the opposite direction to reduce the opening area of the rectangular trough, thereby controlling the flow rate of construction waste entering the screening box 204 and adjusting the feed rate. Figure 3 and Figure 4 As shown, the operator can change the threaded connection between the support frame 201 and the two sets of arc-shaped bars 202 at different positions, causing the support frame 201 to rotate around the hinge point with the frame 1. The screening frame 203 set above the support frame 201 will change with the change of the tilt angle of the support frame 201. The high-frequency vibration generated by the vibrating motor 205 can make the screening box 204 and the screen 206 vibrate continuously, screening the material on the screen 206. For construction waste with poor flowability and fine particles, appropriately increasing the tilt angle can accelerate the movement of the material on the screen 206. The screen 206 is inclined to increase screening efficiency. For materials with good flowability and larger particles, reducing the inclination angle allows the material to stay on the screen for a longer time, ensuring thorough screening and improving screening quality. It is flexible to adjust and easy to use. Large particles after being screened by the screen 206 will flow along the screen 206 to the guide plate 8. Operators can place a container under the guide plate 8 to collect the large particles. Small particles after being screened by the screen 206 will fall into the discharge hopper 6. The rectangular plate 7 can be used to guide the screened material into the discharge hopper 6.
[0043] All technical features in this embodiment can be freely combined according to actual needs.
[0044] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
