Description

Technical Field

[0001] This utility model belongs to the technical field of bleaching powder production equipment, and in particular, it is a finished product vibrating screen for bleaching powder production. Background Technology

[0002] In the production process of bleaching powder, the finished product needs to be screened to remove impurities and ensure the uniformity of particle size. Bleaching powder itself is a powdery substance with small particle size and light weight. During the screening operation of the vibrating screen, the material is constantly thrown up and down, colliding and rubbing against the screen and other components. This makes the powder that was originally aggregated easily disperse into smaller particles, thus forming dust. Traditional vibrating screens used for bleaching powder production can meet basic usage requirements, but their dust handling capacity is weak, which leads to increased environmental pollution, affects the heat dissipation of the equipment, causes the equipment to overheat, and increases the probability of electrical failures.

[0003] A search revealed a Chinese patent document (authorization announcement number CN214132664U), which discloses a vibrating screen for screening and separating feed powder. The screen includes a base plate, a screening chamber, and a three-way pipe. A first discharge channel and a second discharge channel are sequentially fixed to one side of the screening chamber, respectively communicating with the interior of the chamber. A first valve is installed on the first discharge channel, and its end facing away from the screening chamber is connected to the top interface of the three-way pipe via a bend. A second valve is installed on the second discharge channel, and its end facing away from the screening chamber is connected to one side interface of the three-way pipe. This invention offers the advantage of being able to both package feed and collect powder through the three-way pipe, improving the applicability and operability of the device. While the vibrating screen meets basic usage requirements, its dust handling capacity is weak, potentially increasing environmental pollution. It also affects heat dissipation, leading to overheating and increasing the probability of electrical malfunctions. Utility Model Content

[0004] The purpose of this invention is to provide a finished product vibrating screen for bleaching powder production, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a vibrating screen for finished product bleaching powder production, comprising a base for supporting finished bleaching powder, a screening box for screening finished product bleaching powder production is provided on the top of the base, and a dust collection box is connected to the top of the screening box.

[0006] The dust collector has a dust inlet hopper installed on its vertical inner wall. A motor is installed on the top of the dust inlet hopper. The output shaft of the motor is connected to a rotating frame via a coupling. Four filter plate frames for support are symmetrically installed at the ends of the rotating frame. Each of the four filter plate frames contains a filter plate for filtering dust.

[0007] Preferably, the top of the dust inlet hopper is connected to a dust inlet pipe for bleaching powder dust to enter, the inner top wall of the dust collector is connected to an air outlet pipe, and a fan is installed inside the air outlet pipe.

[0008] Preferably, the dust collector is provided with an air outlet at the top and a replacement door for replacing the filter plate is installed on the outer periphery of the dust collector.

[0009] Preferably, the top of the screening box is connected to a feed hopper for bleaching powder to enter, and the vertical inner wall of the feed hopper is symmetrically provided with two rotating grooves for limiting the movement, and the inside of the rotating grooves is connected to a spring.

[0010] Preferably, a rotating shaft is rotatably mounted inside the rotating groove, one end of the spring is connected to the outer periphery of the rotating shaft, and a dust baffle is mounted on the outer periphery of the rotating shaft.

[0011] Preferably, the base has four support feet welded to its top, and each of the four support feet has a vibration spring installed on its top. The end of the vibration spring away from the support foot is connected to the bottom of the screening box.

[0012] Preferably, a vibrator for vibration is installed on the top of the screening box, a vibrating screen plate for vibration of finished product for bleaching powder production is installed inside the screening box, a fine discharge hopper is connected to the bottom of the screening box, and a coarse material discharge port is connected to the side of the screening box.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This vibrating screen for bleaching powder production benefits from the structure of the dust collection box. Dust in the screening box comes into contact with the filter plates through the dust inlet hopper and dust inlet pipe. The filter plates filter the dust, and the filtered gas is discharged through the air outlet pipe and air outlet. The motor drives the rotating frame and filter plate frame to rotate. The filter plate frame rotates the used filter plates away from the dust inlet pipe and air outlet pipe, and new filter plates enter the dust inlet pipe and air outlet pipe to continue filtration. Used filter plates can be removed and replaced through the replacement door. Compared with the traditional vibrating screen for bleaching powder production, which has a weaker dust handling capacity, this structure can improve the dust handling capacity, reduce environmental pollution, and will not affect the heat dissipation of the equipment, thus reducing the probability of electrical failures.

[0015] This vibrating screen for bleaching powder production utilizes the structure of the feed hopper. When bleaching powder enters the hopper, it contacts the dust baffle, compressing it. The dust baffle drives the rotating shaft to rotate within the rotating groove, causing the spring to deform. The bleaching powder then enters the screening box through the gap between the feed hopper and the dust baffle. When no more bleaching powder enters, the spring returns to its original position, driving the rotating shaft and the dust baffle to close the feed hopper and prevent dust from overflowing.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0026] like Figures 1 to 5 The vibrating screen for bleaching powder production shown includes a base 1 for supporting the finished bleaching powder, a screening box 103 for screening the finished product for bleaching powder production is provided on the top of the base 1, and a dust collection box 3 is connected to the top of the screening box 103.

[0027] A dust inlet 301 is installed on the vertical inner wall of the dust collector 3. A motor 4 is installed on the top of the dust inlet 301. The output shaft of the motor 4 is connected to a rotating frame 401 via a coupling. Four filter plate frames 402 are symmetrically installed at the ends of the rotating frame 401 for support. Each of the four filter plate frames 402 contains a filter plate 403 for filtering dust. The top of the dust inlet 301 is connected to a dust inlet pipe 404 for bleaching powder dust to enter. An air outlet 405 is connected to the inner top wall of the dust collector 3. A fan 304 is installed inside the air outlet 405. An air outlet 303 is provided on the top of the dust collector 3. A replacement filter plate 403 is installed on the outer periphery of the dust collector 3. When changing door 302 and vibrating screening, the fan 304 is turned on. The dust in the screening box 103 comes into contact with the filter plate 403 through the dust inlet hopper 301 and dust inlet pipe 404. The filter plate 403 filters the dust. The filtered gas is discharged through the air outlet pipe 405 and air outlet 303. After a period of time, the motor 4 is turned on. The motor 4 drives the rotating frame 401 and the filter plate frame 402 to rotate. The filter plate frame 402 rotates the used filter plate 403 away from the dust inlet pipe 404 and the air outlet pipe 405. The new filter plate 403 enters the dust inlet pipe 404 and the air outlet pipe 405 to continue filtering. The used filter plate 403 can be taken out from the changing door 302 for replacement.

[0028] The top of the screening box 103 is connected to a feed hopper 2 for bleaching powder to enter. The vertical inner wall of the feed hopper 2 is symmetrically provided with two rotating grooves 201 for limiting. The inside of the rotating grooves 201 is connected to a spring 202. The spring 202 is usually a spiral metal strip. When an external force is applied to the spring 202, causing it to wind around the axis, the spring material undergoes elastic deformation. The work done by the external force is converted into the elastic potential energy of the spring and stored. Just like winding up a toy, rotating the key winds up the spring 202, storing energy. A rotating shaft 203 is mounted inside the rotating groove 201. One end of the spring 202 is connected to the outer circumference of the rotating shaft 203. A dust baffle 204 is mounted on the outer circumference of the rotating shaft 203. When bleaching powder enters the feed hopper 2, it contacts and compresses the dust baffle 204, causing the rotating shaft 203 to rotate within the rotating groove 201. This causes the spring 202 to deform, allowing the bleaching powder to enter the screening box 103 through the gap between the feed hopper 2 and the dust baffle 204. When no more bleaching powder enters, the spring 202 returns to its original position, driving the rotating shaft 203 and the dust baffle 204 to close the feed hopper 2, preventing dust from overflowing.

[0029] Four support feet 101 are welded to the top of the base 1, and a vibration spring 102 is installed on the top of each of the four support feet 101. The vibration spring 102 can be a composite spring, combining the advantages of helical springs and rubber springs. The inner part is a metal helical spring, and the outer part is wrapped with rubber material. This type of spring has both the high elastic modulus and load-bearing capacity of metal springs and the good damping and buffering performance of rubber springs, which can better meet the working requirements of vibrating screens. Composite springs are widely used in some large vibrating screens or in applications with high vibration performance requirements. The end of the vibration spring 102 away from the support feet 101 is connected to the bottom of the screening box 103.

[0030] The top of the screening box 103 is equipped with a vibrator 104 for vibration. The working principle of the vibrator 104 is based on the mechanical vibration theory. It generates periodic excitation force in different ways to make the screen box of the vibrating screen vibrate. Common methods include using an eccentric block to generate centrifugal force, which forms an excitation force. A motor drives the eccentric block to rotate at high speed. Because the center of gravity of the eccentric block does not coincide with the center of rotation, centrifugal force is generated during rotation, and the periodic centrifugal force causes the screen box to vibrate. Another method is using an electromagnetic vibrator 104, which utilizes the principle of electromagnetic induction. Alternating current passes through an electromagnet coil to generate an alternating magnetic field, causing the vibrating body to reciprocate under the action of the magnetic field, thus achieving vibration. The screening box 103 is equipped with a vibrating screen plate 105 for vibrating the finished product in the production of bleaching powder. The bottom of the screening box 103 is connected to a fine discharge hopper 106, and the side of the screening box 103 is connected to a coarse material discharge port 107. The bleaching powder to be screened is added from the feed hopper 2 onto the vibrating screen plate 105. The vibrator 104 is turned on, and the vibrator 104 drives the screening box 103 to vibrate. The vibrating screen plate 105 vibrates and screens the bleaching powder. Bleaching powder that meets the size requirements is discharged through the fine discharge hopper 106, while bleaching powder that is too large is discharged through the coarse material discharge port 107.

[0031] Working principle

[0032] This vibrating screen is used for finished product screening in bleaching powder production. In use, the bleaching powder to be screened is first added to the vibrating screen plate 105 from the feed hopper 2. The vibrator 104 is then turned on, causing the screening box 103 to vibrate. The vibrating screen plate 105 vibrates and screens the bleaching powder. Bleaching powder that meets the required size is discharged through the fine discharge hopper 106, while bleaching powder that is too large is discharged through the coarse discharge port 107. When the bleaching powder enters the feed hopper 2, it contacts the dust baffle 204, compressing it. The dust baffle 204 drives the rotating shaft 203 to rotate within the rotating groove 201, causing the spring 202 to deform. The bleaching powder then enters the screening box 103 through the gap between the feed hopper 2 and the dust baffle 204. When the bleaching powder stops entering, the spring 202 returns to its original position. In position, the spring 202 drives the rotating shaft 203 and the dust baffle 204 to close the feed hopper 2 to prevent dust from overflowing. During vibration screening, the fan 304 is turned on, and the dust in the screening box 103 comes into contact with the filter plate 403 through the dust inlet hopper 301 and the dust inlet pipe 404. The filter plate 403 filters the dust, and the filtered gas is discharged through the air outlet pipe 405 and the air outlet 303. After a period of time, the motor 4 is turned on, and the motor 4 drives the rotating frame 401 and the filter plate frame 402 to rotate. The filter plate frame 402 rotates the used filter plate 403 away from the dust inlet pipe 404 and the air outlet pipe 405, and the new filter plate 403 enters the dust inlet pipe 404 and the air outlet pipe 405 to continue filtering. The used filter plate 403 can be taken out from the replacement door 302 for replacement.
