Description

Technical Field

[0001] This utility model belongs to the field of building material processing equipment, and in particular relates to a stone aggregate washing device. Background Technology

[0002] In construction engineering and road building, stone aggregate is a crucial raw material, and its cleanliness directly affects the quality of subsequent products such as concrete and mortar. However, during the mining, transportation, and storage processes, impurities such as mud and dust easily adhere to the surface of stone aggregate, necessitating cleaning treatment. Existing stone aggregate washing equipment mostly adopts a simple rinsing method, which is to spray water directly onto the stone aggregate on the conveyor belt through water pipes. This washing method has obvious drawbacks: on the one hand, the water flow is difficult to fully contact the surface of the stone aggregate, especially the parts where the stone aggregate overlaps with each other, resulting in incomplete cleaning, more impurities remaining, and reduced quality of subsequent products. Utility Model Content

[0003] In view of this, the present invention aims to provide a stone aggregate cleaning device to solve the problem that the traditional washing method results in incomplete cleaning due to the obstruction caused by the stacking of stone aggregates during transportation.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A stone aggregate washing device includes a screening unit mounted on a base frame. The screening unit includes a shell, a mounting plate, and a spring. A filter screen with an arc-shaped structure is installed inside the shell. Two mounting plates are respectively installed on both sides of the shell. A first positioning post is installed on one side of each mounting plate. A spring is installed around the periphery of each first positioning post. One end of the spring is fixedly connected to one side of the mounting plate, and the other end of the spring is fixedly connected to the base frame.

[0005] Furthermore, the screening unit also includes a drive motor, a connecting shaft, a rotating shaft, and an eccentric wheel. One side of the drive motor is fixedly connected to one side of the base frame, and the output end of the drive motor is fixedly connected to one end of the rotating shaft through the connecting shaft. An eccentric wheel is provided at each end of the rotating shaft, and the outer periphery of the rotating shaft is rotatably connected to one side of the housing.

[0006] Furthermore, the stone aggregate washing device also includes a feeding hopper, which is installed on the base frame and located above the screening unit. The output end of the feeding hopper is provided with a discharge channel, which is located inside the screening unit. A valve is installed inside the discharge channel to limit the opening and closing of the discharge channel.

[0007] Furthermore, the stone aggregate washing device also includes a spraying unit, which is located at the upper end of the screening unit. The spraying unit includes a main pipe, a connecting pipe, and a branch pipe. The main pipe is located on one side of the screening unit, and one end of the main pipe is fixedly connected to a water source. The other end of the main pipe is fixedly connected to one end of the connecting pipe. Multiple branch pipes are arranged axially around the periphery of the connecting pipe. The periphery of each branch pipe is fixedly connected to one end of the screening unit at both ends. Each branch pipe has multiple circular holes arranged axially on one side, which are used to spray liquid onto the screening unit.

[0008] Furthermore, the base frame includes a first bracket, a second bracket, a third bracket, and wheels. The lower end of the first bracket is provided with four wheels, which are located on both sides of the first bracket. The second bracket is provided inside the first bracket, and the third bracket is provided on one side of the first bracket. A feeding bin is provided inside the first bracket, and the feeding bin is located above the second bracket. One side of the first bracket is fixedly connected to one side of the drive motor. The upper end of the second bracket is fixedly connected to one end of a spring, and the upper end of the second bracket is provided with multiple second positioning posts, the outer periphery of each second positioning post being located within the inner ring of a spring.

[0009] Furthermore, the stone aggregate washing device also includes a conveying unit comprising a conveyor and a scraper. The outer sides of the conveyor are respectively connected to the inner walls of the second and third supports, and the conveyor is located below the screening unit. A scraper is provided on one side of the conveyor, and the two ends of the scraper are respectively fixedly connected to one side of the third support.

[0010] Compared with the prior art, the stone aggregate washing device of this utility model has the following advantages: (1) The stone aggregate cleaning device of this utility model is provided with a screening unit. The shafts of the drive motor are respectively set with eccentric wheels at both ends to rotate. The outer periphery of the shaft is rotatably connected to one side of the shell. The shell is fixedly connected to the base frame by springs, so that the stone aggregate inside the shell vibrates and reduces stacking. Water is sprayed onto the stone aggregate inside the shell through a diversion pipe with a round hole in the spray unit connected to the output end of the tap water pipe to clean it, so as to thoroughly wash away the impurities on the surface of the stone aggregate and improve the quality of subsequent products.

[0011] (2) The stone aggregate washing device described in this utility model uses a conveying unit set below the screening unit to transport small particles screened out by the screening unit or impurities remaining on the surface of the stone aggregate to the subsequent waste collection point, thereby reducing the pollution of the environment by the impurities.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown, a stone aggregate washing device includes a base frame 1, a feeding hopper 2, a screening unit 3, and a conveying unit 4. The feeding hopper 2 is installed on the base frame 1 for storing materials. The screening unit 3 is installed on the base frame 1 and is located at the output end of the feeding hopper 2. A spraying unit 5 is installed on the screening unit 3 for spraying cleaning liquid. The conveying unit 4 is installed on the base frame 1 and is located below the screening unit 3. By setting up the screening unit 3 and the spraying unit 5, the impurities and residues attached to the surface of the stone aggregate can be washed and screened out. The stone aggregate is shaken by the screening unit 3 to prevent the stone aggregate from sticking together and causing incomplete cleaning. The screening unit 3 is set at a small angle. Under the shaking action of the screening unit 3, the stone aggregate slowly moves down in the screening unit 3. At the same time, the stone aggregate is sprayed with water for cleaning by the spraying unit 5. The conveying unit 3 can collect and treat the impurities and residues screened out from the periphery of the stone aggregate, reducing environmental pollution caused by random discharge.

[0020] like Figure 2-3As shown, the screening unit 3 includes a housing 31, a mounting plate 32, and a spring 33. A filter screen 311 is installed inside the housing 31, and the filter screen 311 has an arc-shaped structure. Two mounting plates 32 are respectively installed on both sides of the housing 31. A first positioning post 321 is installed on one side of each mounting plate 32, and a spring 33 is installed around the periphery of each first positioning post 321. One end of the spring 33 is fixedly connected to one side of the mounting plate 32, and the other end of the spring 33 is fixedly connected to the base frame 1. By setting the positioning post 321, the spring 33 can be accurately positioned and effectively supported, preventing the spring 33 from shifting and causing damage to the equipment, thus improving the service life of the equipment. By setting the filter screen 311 with an arc-shaped structure, and the arc-shaped surface facing away from the stone aggregate, it is beneficial to the screening and cleaning of the stone aggregate.

[0021] The screening unit 3 also includes a drive motor 34, a connecting shaft 35, a rotating shaft 36, and an eccentric wheel 37. One side of the drive motor 34 is fixedly connected to one side of the base frame 1, and the output end of the drive motor 34 is fixedly connected to one end of the rotating shaft 36 through the connecting shaft 35. An eccentric wheel 37 is respectively provided at both ends of the rotating shaft 36, and the outer periphery of the rotating shaft 36 is rotatably connected to one side of the housing 31. The drive motor 34 drives the rotating shaft 36 with the eccentric wheel 37 to rotate, thereby causing the housing 31 to shake, so that the housing 31 can screen the stone aggregate inside. The drive motor 34 is existing technology, model YE4-H63-355, and the connecting shaft 35 is a universal coupling in the prior art, model SWC180WF.

[0022] like Figure 4 As shown, the base frame 1 includes a first support 11, a second support 12, a third support 13, and wheels 14. Four wheels 14 are provided at the lower end of the first support 11, and the four wheels 14 are located on both sides of the first support 11. The second support 12 is located inside the first support 11, and the third support 13 is located on one side of the first support 11. A feeding hopper 2 is located inside the first support 11, and the feeding hopper 2 is located above the second support 12. One side of the first support 11 is fixedly connected to one side of the drive motor 34. The upper end of the second support 12 is fixedly connected to one end of a spring 33, and multiple second positioning posts 121 are provided at the upper end of the second support 12. The periphery of each second positioning post 121 is located within the inner ring of a spring 33. By setting the first support 11, the second support 12, and the third support 13, the feeding hopper 2, the screening unit 3, and the conveying unit 4 are installed in layers, improving the continuity of the device's operation. The third support 13 provides effective support for one side of the conveying unit 4. The wheels 14 increase the flexibility and applicability of the device.

[0023] like Figure 5As shown, the output end of the feeding hopper 2 is provided with a discharge channel 21, and the discharge channel 21 is located inside the screening unit 3. A valve 22 is provided inside the discharge channel 21. The valve 22 is used to limit the opening and closing of the discharge channel 21. The valve 22 is provided and is controlled by an electrical signal. The worker controls the opening degree of the valve 22 according to the actual situation on site to prevent the valve 22 from being opened too wide, resulting in incomplete screening and washing, or the valve 22 from being opened too small, resulting in waste of manpower and resources. The valve 22 is the Bray752 series bidirectional knife gate valve in the prior art.

[0024] like Figure 6 As shown, the conveying unit 4 includes a conveyor 41 and a scraper 42. The outer sides of the conveyor 41 are respectively connected to the inner walls of the second support 12 and the third support 13. The conveyor 41 is located below the screening unit 3. A scraper 42 is provided on one side of the conveyor 41, and the two ends of the scraper 42 are respectively fixedly connected to one side of the third support 13. The conveyor 41 is used to collect the impurities washed out in the screening unit 3 and transport them to a unified collection position for unified treatment, preventing environmental pollution caused by random discharge. The scraper 42 is used to clean the cement mixture on the surface of the conveyor 41 to prevent the cement mixture from adhering to the surface of the conveyor 41 and causing damage to the conveyor 41. The conveyor 41 is a trough belt conveyor in the prior art.

[0025] like Figure 7-8 As shown, the spraying unit 5 includes a main pipe 51, a connecting pipe 52, and a branch pipe 53. The main pipe 51 is located on one side of the screening unit 3, and one end of the main pipe 51 is fixedly connected to a water source. The other end of the main pipe 51 is fixedly connected to one end of the connecting pipe 52. Multiple branch pipes 53 are arranged axially around the connecting pipe 52. The two ends of each branch pipe 53 are fixedly connected to one end of the screening unit 3. Multiple round holes 531 are provided axially on one side of each branch pipe 53. The round holes 531 are used to spray liquid into the screening unit 3. By setting multiple branch pipes 53, the stone aggregate in the screening unit 3 is graded and cleaned, improving the cleaning effect and the quality of subsequent products.

[0026] The working process of a stone aggregate washing device: The stone aggregate to be cleaned is poured into the feeding hopper 2 through the transmission equipment. The valve 22 in the discharge channel 21 at the output end of the feeding hopper 2 is opened to control the discharge speed, so that the stone aggregate is accurately conveyed to the screening unit 3 below along the discharge channel 21. The drive motor 34 is started, and its output end drives the rotating shaft 36 to rotate through the connecting shaft 35. The eccentric wheels 37 at both ends of the rotating shaft 36 rotate with the shaft, generating a vibration force. The vibration force causes the shell 31 of the screening unit 3 to vibrate. At the same time, the springs 33 on the mounting plates 32 on both sides of the shell 31 are fitted around the first positioning post 321 and cooperate with the second positioning post 121 on the second bracket 12 to maintain the stable vibration of the shell 31, ensuring that the arc-shaped filter screen 311 inside the shell efficiently screens. During the screening process, the water source of the main pipe 51 of the spray unit 5 is connected. The water flows through the main pipe 51 into the connecting pipe 52, and then through the outer side of the connecting pipe 52. Multiple diversion pipes 53 spray evenly onto the stone aggregate inside the shell 31 through round holes 531 on one side of the diversion pipes 53, achieving the washing of impurities on the surface of the aggregate. The vibrating arc-shaped filter screen 311 leaves the cleaned stone aggregate above the filter screen 311, which can be collected through the shell outlet later. Meanwhile, mud, sand, and small particle impurities pass through the gaps in the filter screen and fall directly onto the conveyor 41 below. The conveyor 41 is connected to the inner walls of the second support 12 and the third support 13 on both sides. When the conveyor 41 is started, the scraper 42 on the surface is fixed at both ends to one side of the third support 13. One side of the scraper contacts one side of the conveyor 41, assisting in cleaning the periphery of the conveyor 41 and conveying impurities to the outside of the equipment, thus completing the waste cleaning. Throughout the process, the wheels 14 under the base frame 1 facilitate the movement of the equipment; the third support 13 helps to fix the conveyor 41 and the scraper 42, ensuring the stability of the overall structure.

[0027] The control method in this embodiment is controlled by a controller. The controller circuit can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this document is mainly used to protect mechanical devices, and the control method and circuit connection will not be explained in detail here.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
