Description

Technical Field

[0001] This utility model relates to the field of water-coated sand production technology, specifically a screening device for water-coated sand production that facilitates material feeding. Background Technology

[0002] Water-coated sand is a raw material for artificial granite. During the production of water-coated sand, the raw material needs to be screened and cleaned before further mixing and processing. Most existing water-coated sand screening devices put all the raw materials into the screening device and process them all at once. This method not only results in high screening pressure and low screening efficiency, but also makes it inconvenient for continuous screening of water-coated sand raw materials.

[0003] Patent application CN218049249U discloses a screening device for water-coated sand production that facilitates material feeding. The device includes a barrel with a storage chamber at the top. This invention uses a limiting roller to feed water-coated sand raw materials in batches into a trough. The raw materials collide on a dust removal frame, achieving dust removal. A mist spray from the rinsing pipe and a rotating rod further agitate the materials on the chassis, resulting in friction cleaning. The materials are then dried with hot air in the discharge channel. This device enables one-time screening and cleaning of water-coated sand raw materials, allowing for continuous processing and improving both the screening efficiency and quality.

[0004] However, in practical applications, traditional water-coated sand screening devices can only remove lighter impurities such as dust. Due to their weight, clumps or lumps of impurities in the water-coated sand raw material cannot be selected by the airflow of the exhaust fan for filtration. The screening efficiency and processing quality of water-coated sand raw material need to be improved. For example, in the production of water-coated sand, the raw material may clump together or contain other impurities of a certain weight. Due to their weight, these impurities cannot be filtered out by the exhaust fan during the filtration process and cannot be removed during production, resulting in a need to improve production quality. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the actual needs, and provide a screening device for water-coated sand production that is easy to feed, so as to solve the technical problem that the water-coated sand raw material is clumped together or contains other impurities with a certain weight, which cannot be selected by the air volume of the exhaust fan for filtration and removal during the filtration process due to their weight.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a screening device for water-coated sand production that facilitates feeding is designed, including a barrel body, a storage cavity at the top of the barrel body, a receiving plate fixedly and horizontally arranged inside the storage cavity, side plates fixedly connected to both sides of the receiving plate, a rack fixedly connected to the top of the side plates, a rotating roller slidably connected to the upper end of the receiving plate, a cleaning brush fixedly connected to the outside of the rotating roller, drive gears fixedly connected to both ends of the rotating roller, the drive gears meshing with the rack, a first discharge port on both sides of the receiving plate, and a discharge box fixedly connected to the outside of the first discharge port.

The dust particles inside the barrel are then collected through the exhaust pipe, thus achieving the storage of the water-coated sand raw material.

[0012] Preferably, the bottom of the dust removal frame is provided with a rinsing pipe, one end of which extends to the outside of the barrel and is fixedly connected to a water tank, and the bottom of the rinsing pipe is fixedly connected with several water nozzles.

The bottom of the sweeping bar abuts against the bottom plate, and the bottom of the bottom plate is provided with a discharge channel.

[0015] In practical applications, the bottom of the flushing pipe has a rotating rod that rotates circumferentially, and the bottom of the rotating rod is fixedly connected to a sweeping bar.

[0016] Preferably, a drive motor is fixedly connected to the bottom of the barrel, the output end of the drive motor is connected to a central shaft, and the other end of the central shaft is fixedly connected to the bottom of the dust removal frame.

[0017] In practical applications, the rotation requirements of the above mechanisms are achieved by driving a motor to rotate the central shaft.

[0018] Preferably, the rotating rod is connected to the central shaft, a track plate is fixedly connected to the inner wall of the barrel, the track plate is provided with an annular track, and the extension end of the rotating rod is limited to slide within the annular track.

[0019] In practical applications, the working principle and beneficial effects of innovative components are discussed.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a combination of receiving plate and rotating roller to filter out other impurities that are agglomerated or large in the water-coated sand raw material. The rotating roller collects the impurities, thereby improving the screening efficiency of the water-coated sand raw material. 2. This utility model uses a combination of rotating rollers and cleaning brushes to clean up impurities accumulated on the receiving plate and some impurities stuck in the holes of the receiving plate.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A screening device for water-coated sand production that facilitates material feeding, see [link to example]. Figures 1 to 5 The container includes a barrel body 100, a storage chamber 110 at the top of the barrel body 100, a receiving plate 120 fixedly and horizontally arranged inside the storage chamber 110, side plates 130 fixedly connected to both sides of the receiving plate 120, a rack 140 fixedly connected to the top of the side plates 130, a rotating roller 150 slidably connected to the upper end of the receiving plate 120, a cleaning brush 160 fixedly connected to the outside of the rotating roller 150, a drive gear 170 fixedly connected to both ends of the rotating roller 150, the drive gear 170 meshing with the rack 140, a first discharge port 121 on both sides of the receiving plate 120, and a storage box 122 fixedly connected to the outside of the first discharge port 121. The water-coated sand raw material is filtered by the receiving plate 120 and the rotating roller 150 to remove other impurities that are lumpy or large in size. The rotating roller 150 collects the impurities and cleans the impurities accumulated on the receiving plate 120 and some of the impurities stuck in the holes of the receiving plate 120, thereby improving the screening efficiency of the water-coated sand raw material.

[0028] For details, see Figures 1 to 5The bottom of the receiving plate 120 is provided with a feeding port 200. A roller 210 is rotatably positioned between the feeding ports 200. Multiple material troughs 211 are arranged in a circular array around the roller 210. A dust collector frame 220 is provided at the bottom of the roller 210. An exhaust pipe 230 is provided on one side of the dust collector frame 220. The exhaust pipe 230 extends to the outside of the barrel 100 and connects to a filter box 231. An exhaust fan 232 is connected to the top of the filter box 231. A rinsing pipe 240 is provided at the bottom of the dust collector frame 220. One end of the rinsing pipe 240 extends to the outside of the barrel 100 and is fixedly connected to a water tank 241. Several water nozzles 242 are fixedly connected to the bottom of the rinsing pipe 240. A rotating rod 250 is circumferentially rotated at the bottom of the flushing pipe 240. A sweeping bar 251 is fixedly connected to the bottom of the rotating rod 250. The bottom of the sweeping bar 251 abuts against the bottom plate 252. The bottom of the bottom plate 252 is provided with a discharge channel 260. A drive motor 270 is fixedly connected to the bottom of the barrel 100. The output end of the drive motor 270 is connected to a central shaft 280. The other end of the central shaft 280 is fixedly connected to the bottom of the dust collector 220. The rotating rod 250 is connected to the central shaft 280. A track plate 290 is fixedly connected to the inner wall of the barrel 100. An annular track 291 is provided inside the track plate 290. The extension end of the rotating rod 250 is limited to slide within the annular track 291.

[0029] The water-coated sand material falling into the trough plate 211 is caused to fall in batches by the roller 210 and the trough plate 211. The water-coated sand material collides with the dust collector 220, causing dust particles to spread around the dust collector 220. The dust particles in the barrel 100 are recovered by the exhaust pipe 230 to realize the storage of water-coated sand material. The material is coated with water by the spray of the flushing pipe 240. The rotating rod 250 moves the material on the bottom plate 252 to realize the further friction and cleaning of the material. The rotating rod 250 is stably rotated in a circular manner by the track plate 290 and the ring track 291. The material falls freely into the corresponding discharge channel 260, thereby realizing the screening and cleaning of water-coated sand material. Continuous processing of water-coated sand material can be carried out, which improves the screening efficiency and screening quality of water-coated sand material.

[0030] In practical application, this solution works as follows: As construction workers require, the receiving plate 120 and rotating roller 150 filter the water-coated sand material, removing clumps or large pieces of impurities. The rotating roller 150 collects these impurities, clearing accumulated impurities and some stuck in the holes of the receiving plate 120. The shaft roller 210 and trough plate 211 cause the water-coated sand material falling into the trough plate 211 in batches. The material collides with the dust collector 220, causing dust particles to disperse around the dust collector 220. Dust particles inside the barrel 100 are recovered through the exhaust pipe 230 to store the water-coated sand raw material. The raw material is coated with moisture through the spraying of the flushing pipe 240. The rotating rod 250 moves the raw material on the bottom plate 252 to achieve further friction cleaning. The rotating rod 250 is stably rotated in a circular manner through the track plate 290 and the ring track 291. The raw material falls freely into the corresponding discharge channel 260, thereby realizing the screening and cleaning of the water-coated sand raw material. This allows for continuous processing of the water-coated sand raw material, improving the screening efficiency and screening quality.
