Description

Technical Field

[0001] This utility model relates to the technical field of plate feeders, specifically a plate feeder with a spraying device. Background Technology

[0002] Plate feeders are generally classified into heavy-duty, medium-duty, and light-duty types, and are commonly used feeding equipment in mineral processing plants. A plate feeder consists of transmission components, a base assembly, and working components. Different models of plate feeders are classified by transmission method into right-hand drive and left-hand drive. Right-hand drive feeders have the transmission system on the right side of the machine in the direction of material flow, while left-hand drive feeders have the transmission system on the opposite side.

[0003] An existing patent (publication number: CN216917509U) discloses a plate feeder with a spray device. It supplies water to the spray pipes via a water pump. The water storage tank can be designed with dimensions larger than the chain plate to collect the falling rinsing liquid, or it can be designed with the same dimensions as the chain plate. A baffle is installed between the chain plate and the water storage tank to prevent splashing during rinsing and to increase the recovery rate of the rinsing liquid. The water storage tank can be divided into a clear water tank and a sedimentation tank, with the spray pipes connected to the clear water tank. This design allows for timely cleaning of residual material after use of the plate feeder, and is energy-saving, environmentally friendly, and makes full use of water resources.

[0004] However, the above technical solutions still have certain defects. When cleaning the material on the chain plate through the water spray pipe, the cleaned material will fall into the water storage tank, which will seriously affect the subsequent cleaning by the staff. At the same time, it will also cause blockage between the water storage tank and the water spray pipe, affecting the cleaning efficiency. Therefore, a plate feeder with a spray device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a plate feeder with a spraying device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plate feeder with a spraying device, comprising a frame, a U-shaped frame fixed at the top of the frame, and two sets of the frame, with a screening and collecting assembly between the two sets of the frame, and a drying assembly at the bottom of the U-shaped frame;

[0007] The screening and collection assembly includes a water tank located at the lower end between two sets of frames. A spray pipe is connected to one side of the water tank, and multiple sets of return springs are fixed to one side of the top of the water tank. A fixing plate is provided at the top of the multiple sets of return springs. A screen is installed on one side of the fixing plate. A movable plate is provided on the side of the screen away from the fixing plate. Round rods are rotatably connected to the other side of the top of the water tank on both sides inside the movable plate. A rotating shaft is provided directly below the screen. Multiple sets of cylinders are fixed to the surface of the rotating shaft. Ball-head rods are slidably connected inside the multiple sets of cylinders. A helical spring is fixed between the end of the ball-head rod and the inner wall of the cylinder. A collection box is provided on the side of the fixing plate away from the screen.

[0008] As a preferred technical solution, two sets of conveying rollers are provided between the two sets of frames, and the outer wall of the curved surface of the conveying rollers is driven by a chain plate. One end of one set of conveying rollers is provided with a servo motor installed on one side of one set of frames.

[0009] As a preferred technical solution, the spray pipe is provided in two sets, and the two sets of spray pipes are located directly below the chain plate.

[0010] As a preferred technical solution, a water pump is installed at the connection end between the water storage tank and the spray pipe.

[0011] As a preferred technical solution, a first pulley is fixed at the end of the conveying rollers away from the servo motor, a belt is driven to the surface of the first pulley, and a second pulley is driven to the end of the inner wall of the belt away from the first pulley, and the second pulley is fixed to the rotating shaft.

[0012] As a preferred technical solution, baffles are fixed at both the front and rear ends of the top of the screen, and the screen is inclined at the top of the water storage tank.

[0013] As a preferred technical solution, the drying assembly includes multiple sets of electronic fans installed at the bottom of the inner wall of the U-shaped frame, each set of electronic fans is provided with an electric heating element directly below it, and a scraper fixed between the two sets of frames is attached to the bottom of the chain plate.

[0014] In summary, the present invention has the following main advantages:

[0015] 1. This utility model uses a spray pipe to cause the cleaned material to fall onto the screen, while the water sprayed from the spray pipe also falls back into the water storage tank through the screen, improving the water recycling rate. The cylinder drives the ball head rod to rotate, applying force to the screen surface and causing the screen to vibrate. This causes the material falling onto the screen to move towards the collection box until it enters the collection box for subsequent centralized processing. By separating the material from the water inside the storage tank, the material is prevented from falling into the storage tank and hindering subsequent cleaning. At the same time, the vibration of the screen can prevent material from accumulating and clogging, ensuring that waste slides quickly into the collection box.

[0016] 2. This utility model uses an electronic fan to accelerate airflow and quickly evaporate moisture from the surface of the chain plate. The electric heating element can heat the circulating air, further shortening the drying time and preventing residual moisture after spray cleaning from causing chain plate corrosion. At the same time, the scraper can remove highly absorbent materials from the chain plate. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] The embodiments of this utility model will be described below based on its overall structure.

[0027] A plate feeder with a spraying device, such as Figure 1-5As shown, it includes a frame 100, a U-shaped frame 110 fixed at the top of the frame 100, and the frame 100 is provided in two sets. A screening and collection assembly 200 is provided between the two sets of frames 100, and a drying assembly 300 is provided at the bottom of the U-shaped frame 110.

[0028] The screening and collection assembly 200 includes a water storage tank 210 located at the lower end between two sets of frames 100. A spray pipe 220 is connected to one side of the water storage tank 210, and multiple sets of return springs 230 are fixed to one side of the top of the water storage tank 210. A fixing plate 240 is provided at the top of the multiple sets of return springs 230. A screen 250 is installed on one side of the fixing plate 240. A movable plate 260 is provided on the side of the screen 250 away from the fixing plate 240. Round rods 261 rotatably connected to the other side of the top of the water storage tank 210 are provided on both sides inside the movable plate 260. A rotating shaft 2910 is provided directly below the screen 250. Multiple sets of cylinders 2920 are fixed to the surface of the rotating shaft 2910. Ball-head rods 2930 are slidably connected inside the multiple sets of cylinders 2920. A helical spring 2940 is fixed between the end of 2930 and the inner wall of the cylinder 2920. A collection box 2950 is provided on the side of the fixing plate 240 away from the screen 250. Two sets of conveying rollers 130 are provided between the two sets of frames 100. A chain plate 120 is driven on the curved outer wall of the conveying roller 130. A servo motor 140 is installed on one side of a set of frames 100 at one end of a set of conveying rollers 130. A first pulley 270 is fixed at the end of a set of conveying rollers 130 away from the servo motor 140. A belt 280 is driven to the surface of the first pulley 270. A second pulley 290 is driven to the inner wall of the belt 280 away from the first pulley 270. The second pulley 290 is fixed to the rotating shaft 2910.

[0029] By starting the servo motor 140, the conveyor roller 130 is driven to rotate, which in turn drives the chain plate 120 for transmission. Subsequently, the spray pipe 220 sprays water through the water tank 210 to clean the material remaining on the surface of the chain plate 120. The cleaned material falls onto the screen 250, and the water sprayed from the spray pipe 220 also falls back into the water tank 210 through the screen 250, further improving water recycling. When the conveyor roller 130 rotates, it drives the first pulley 270 to rotate synchronously. The first pulley 270 drives the second pulley 290 to rotate via the belt 280, which in turn drives the rotating shaft 2910 and multiple sets of cylinders 2920 to rotate. When the cylinder 2920 drives the ball head rod 2930 to rotate and abut against the bottom of the screen 250, the ball head rod 2930 will compress the spiral spring 2940 to contract inward, thereby continuously applying force to the surface of the screen 250. Under the action of the return spring 230 and the round rod 261, the screen 250 vibrates, which causes the material falling onto the screen 250 to move towards the collection box 2950 until the material enters the collection box 2950 for subsequent centralized processing. By separating the material from the water inside the water tank 210, the material is prevented from falling into the water tank 210, which would make subsequent cleaning difficult. At the same time, the vibration of the screen 250 can prevent the material from accumulating and clogging, ensuring that the waste slides quickly into the collection box 2950.

[0030] Please refer to this carefully. Figure 3 There are two sets of spray pipes 220, which are located directly below the chain plate 120. A water pump is installed at the connection end between the water storage tank 210 and the spray pipe 220.

[0031] By placing the spray pipe 220 directly below the chain plate 120, residual material on the chain plate 120 can be cleaned more effectively.

[0032] Please refer to this carefully. Figures 1 to 4 The screen 250 has baffles 251 fixed at both the front and rear ends of the top, and the screen 250 is inclined at the top of the water storage tank 210.

[0033] By setting baffle 251, the material can be effectively dropped from both sides of screen 250. By tilting screen 250, the material can be better slid into collection box 2950.

[0034] Please refer to this carefully. Figure 2 The drying assembly 300 includes multiple sets of electric fans 310 installed at the bottom of the inner wall of the U-shaped frame 110. Each set of electric fans 310 is provided with an electric heating element 320 directly below it. A set of scrapers 330 fixed between the two sets of frames 100 is attached to the bottom of the chain plate 120.

[0035] After the residual material on the chain plate 120 is cleaned, the servo motor 140 drives the chain plate 120 to rotate continuously through the conveyor roller 130. Then, the electric fan 310 is started to accelerate the air flow and quickly evaporate the moisture on the surface of the chain plate 120. The electric heating element 320 can heat the circulating air, further shortening the drying time and preventing the chain plate 120 from rusting due to residual moisture after spray cleaning. At the same time, the scraper 330 can scrape off the highly absorbent material from the chain plate 120.

[0036] During use, the spray pipe 220 cleans the material remaining on the surface of the chain plate 120, causing the cleaned material to fall onto the screen 250. Simultaneously, water sprayed from the spray pipe 220 also passes through the screen 250 and falls back into the water storage tank 210, further improving water recycling. The cylinder 2920 drives the ball head rod 2930 to rotate, applying force to the surface of the screen 250, causing it to vibrate. This causes the material falling onto the screen 250 to move towards the collection box 2950 until it enters the collection box 2950 for subsequent centralized processing. By separating the material from the water inside the water storage tank 210, the material is prevented from being washed away. If the material falls into the water storage tank 210, it will be difficult to clean it later. At the same time, the vibration of the screen 250 can prevent the material from accumulating and clogging, ensuring that the waste slides quickly into the collection box 2950. After the residual material on the chain plate 120 is cleaned, the electric fan 310 is started to accelerate the air flow and quickly evaporate the moisture on the surface of the chain plate 120. The electric heating element 320 can heat the circulating air, further shortening the drying time and preventing the chain plate 120 from rusting due to residual moisture after spray cleaning. At the same time, the scraper 330 can scrape off the highly absorbent material from the chain plate 120. The parts not mentioned in this device are the same as or can be implemented using existing technology.
