Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a raw material vibrating screening device for concrete processing. Background Art

[0002] The raw materials used in concrete processing typically include cement, aggregate, sand, and water. Cement is the cementitious material for concrete, while aggregate and sand serve as fillers. Water is used to mix the concrete and form a slurry. After these raw materials are mixed in the right proportions, they undergo a process of vibration, pouring, and curing, ultimately forming a solid concrete structure. Vibratory screening equipment for concrete processing is primarily used to screen raw materials such as sand and stone required in the concrete production process. It uses a vibrating screen to grade the raw materials, ensuring that their quality and particle size meet production requirements.

[0003] After searching, the existing Chinese patent announcement number is: CN219965518U, which provides a raw material screening device for concrete production and processing. This patent sets a driving mechanism so that the screening device has a repeated screening function when in use, which can make the sand and gravel undergo more detailed screening, and avoid the sand and gravel screening being affected by the feeding speed, resulting in a part of the fine sand being mixed into the coarse sand and discharged before being screened by the filter during the screening process, resulting in poor screening effect. The setting of the driving mechanism effectively solves this problem. Compared with traditional screening devices, it is more outstanding in screening effect and more practical.

[0004] Although the above patent can utilize a driving mechanism to improve the screening effect, the above-mentioned raw material screening device for concrete production and processing still has the following problems: the mesh holes of the screen surface are often blocked and difficult to clean.

[0005] In view of the above problems, a raw material vibration screening device for concrete processing is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a raw material vibration screening device for concrete processing, which solves the problem in the background art that the screen mesh is easily blocked.

[0009] As a further description of the above technical solution: the cleaning mechanism includes a water tank, a water pump is fixedly connected to the top of the water tank, a water pipe is fixedly connected to the top of the water pump, the other end of the water pipe is fixedly connected to a fixed plate, and a plurality of high-pressure nozzles are fixedly connected to the bottom of the fixed plate;

[0010] By adopting the above technical solution, the high-pressure nozzle can regularly clean the sieve plate, which is helpful to prevent the occurrence of sieve hole blockage, thereby maintaining high-efficiency operation of the screening device.

[0011] As a further description of the above technical solution: a first motor is fixedly connected to the top left side of the box body, and the first motor is fixedly connected to a large particle vibration screen plate;

[0012] By adopting the above technical solution, the motor can directly drive the large-particle vibrating screen plate to generate vibration, thereby promoting the separation of coarse concrete raw materials on the screen plate and improving the screening efficiency.

[0013] As a further description of the above technical solution: a first material receiving plate is fixedly connected to the right side of the large particle vibration screen plate;

[0014] By adopting the above technical solution, direct connection with the material receiving plate can reduce vibration loss and structural deformation of the device.

[0015] As a further description of the above technical solution: a second motor is fixedly connected to the bottom left side of the box body, and the second motor is fixedly connected to a small particle vibration screen plate;

[0016] By adopting the above technical solution, the motor can directly drive the small particle vibrating screen plate to generate vibration, which can effectively promote the rapid transmission and separation of fine concrete raw materials on the screen plate.

[0017] As a further description of the above technical solution: a second material receiving plate is fixedly connected to the right side of the small particle vibration screen plate;

[0018] By adopting the above technical solution, connecting the material receiving plates can extend the service life of the vibration screening device.

[0019] As a further description of the above technical solution: four support columns are fixedly connected to the bottom of the box, and the bottom of the support columns is fixedly connected to the bottom plate;

[0020] By adopting the above technical solution, the support column can effectively reduce the vibration and shock generated by the box during operation.

[0021] As a further description of the above technical solution: a waste hopper is provided through and on the bottom of the inner wall of the box.

[0022] By adopting the above technical solution, waste can be collected and diverted in a timely manner using a waste hopper, while reducing the accumulation of waste in the work area, which helps to optimize the concrete production and processing process and improve production efficiency.

The inner wall of the support plate 3 is fixedly connected to a support bar 4, and the top of the support bar 4 is fixedly connected to a rotating motor 5. The output end of the rotating motor 5 is fixedly connected to a rotating shaft 6, and an outer ring of the rotating shaft 6 is fixedly connected to a stirrer 7. The bottom of the support plate 3 passes through and is fixedly connected to a heating barrel body 8, and the bottom of the heating barrel body 8 is fixedly connected to a discharge pipe 9.
