A discharge pipe is fixedly inserted into the bottom of one outer wall of the housing. This invention allows materials to move back and forth in the screen box, achieving raw material screening and improving screening efficiency. While the device meets basic screening requirements, the screening process can be harmful to the respiratory system, impact the environment, and increase equipment damage. Utility Model Content

[0004] The purpose of this invention is to provide a raw material screening device for glass fiber production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material screening device for glass fiber production, comprising a screening box for screening raw materials for glass fiber production, a filter box for filtering dust generated during the screening of raw materials for glass fiber production, a sliding frame installed at the bottom of the filter box, a pushing column connected to the inside of the sliding frame via a second spring, spring supports installed at both ends of the second spring, a sliding column installed at the end of the pushing column away from the second spring, a first filter frame installed on the outer periphery of the sliding column, a filter plate installed inside the first filter frame, a dust collection box installed on the side of the first filter frame, a sealing cover installed on the top of the filter box, an air outlet pipe connected to the side of the filter box, and a fan installed inside the air outlet pipe.

[0006] Preferably, the top of the screening box is provided with a sealing plate, the top of the sealing plate is provided with a feed inlet, the top of the sealing plate is equipped with a sliding base, the outer periphery of the sliding base is connected with a connecting rod, and the end of the connecting rod away from the sliding base is connected to a second filter frame.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0013] This raw material screening device for glass fiber production benefits from the structure of the filter box. When the fan is turned on, the dust generated during the screening of raw materials for glass fiber production enters the filter box through the air inlet. The dust is adsorbed by the filter plates. Due to the vibration of the screening box, the first filter frame moves the filter plates left and right. Due to the vibration effect, the dust adsorbed on the filter plates is shaken off and falls into the dust collection box. This structure reduces the harm to the respiratory system during the screening of raw materials for glass fiber production, reduces the impact on the environment, and reduces equipment damage.

[0014] This raw material screening device for glass fiber production benefits from the structure of the feeding hood. When the raw material for glass fiber production is pressed down on the feeding baffle, the feeding baffle separates, the vibration motor is turned on, and the vibration motor drives the screening box to vibrate. The irregular baffle vibrates with the screening box and slides left and right to prevent the raw material for glass fiber production from clogging. This structure can prevent the raw material from clogging the feeding port and prevent dust from overflowing. Attached Figure Description

[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 6 The device shown is a raw material screening device for glass fiber production, including a screening box 1 for screening raw materials for glass fiber production. A filter box 3 is installed on the top of the screening box 1 to filter dust generated during the screening of raw materials for glass fiber production. A sliding frame 314 is installed at the bottom of the filter box 3. A pushing column 312 is connected to the inside of the sliding frame 314 via a second spring 313. Spring supports 315 are installed at both ends of the second spring 313. A sliding column 311 is installed at the end of the pushing column 312 away from the second spring 313. A first filter frame 310 is installed on the outer periphery of the sliding column 311. The inside of the first filter frame 310... The filter box 3 is equipped with a filter plate 302, a dust collection box 309 is installed on the side of the first filter frame 310, a sealing cover 303 is installed on the top of the filter box 3, an air outlet duct 305 is connected to the side of the filter box 3, and a fan 304 is installed inside the air outlet duct 305. When the fan 304 is turned on, the dust generated during the screening of raw materials for glass fiber production enters the filter box 3 through the air inlet 301. The dust is adsorbed by the filter plate 302. Due to the vibration of the screening box 1, the first filter frame 310 drives the filter plate 302 to move left and right. Due to the vibration effect, the dust adsorbed on the filter plate 302 is shaken off and falls into the dust collection box 309.

[0027] The top of the screening box 1 is provided with a sealing plate 101, the top of the sealing plate 101 is provided with a feed inlet 206, the top of the sealing plate 101 is provided with a sliding base 308, the outer periphery of the sliding base 308 is connected with a connecting rod 306, and the end of the connecting rod 306 away from the sliding base 308 is connected with a second filter frame 307.

[0028] An air inlet 301 is provided on the top of the sealing plate 101, and a feeding hood 2 is installed on the top of the sealing plate 101. A feeding baffle 201 is installed on the vertical inner wall of the feeding hood 2 via a third spring 202. A sliding groove 204 is provided on the vertical inner wall of the feeding hood 2. A shaped baffle 203 is slidably connected to the inside of the sliding groove 204 via a fourth spring 205. When the raw materials for glass fiber production are poured into the feeding hood 2, the raw materials for glass fiber production press down on the feeding baffle 201, and the feeding baffle 201 separates. The vibration motor 108 is turned on, and the vibration motor 108 drives the screening box 1 to vibrate. The shaped baffle 203 vibrates with the screening box 1 and slides left and right to prevent the raw materials for glass fiber production from clogging.

[0029] The screening box 1 is equipped with a screening rack 105, on which a screening mesh 102 is installed. The raw materials for glass fiber production fall onto the screening mesh 102 through the feed port 206. The side of the screening box 1 is connected to a coarse material outlet 103 and a fine material outlet 104. Due to vibration, the screening mesh 102 screens the raw materials for glass fiber production. The fine material falls to the bottom of the screening box 1 and is collected from the fine material outlet 104. The coarse material is collected from the coarse material outlet 103. The bottom of the screening box 1 is connected to a vibration connecting frame 109. A vibration motor 108 is installed on the side of the vibration connecting frame 109. The vibration motor 108 is covered with a protective shell. The vibration motor 108 is existing technology. For reference (YZO-20-4), an eccentric block is installed at both ends of the motor shaft. When the motor rotates, the centrifugal force generated by the eccentric block causes the motor to vibrate. This vibration can be transmitted to other equipment or materials through the motor base or connecting device, thereby realizing various industrial applications. The bottom of the screening box 1 is connected to a support frame 107 via a first spring 106. The first spring 106 is a high-strength spring with internal limit posts to prevent excessive displacement of the screening box 1. The box body needs to withstand the weight of the raw materials and the vibration generated by the vibrating motor, therefore it should have high strength. High-strength steel, such as Q345 steel, is generally selected. This type of steel has good yield strength and tensile strength, ensuring that the box body will not deform or crack during long-term use. To prevent raw material leakage and dust emission, the box body should have good sealing performance. Sealing materials such as sealant and rubber sealing strips can be used at the joints of the box body to ensure the sealing performance of the box body.

[0030] Working principle

[0031] In operation, the raw material screening device for glass fiber production first pours the raw material into the feed hood 2. The raw material presses down on the feed baffle 201, causing the baffle 201 to separate. Then, the vibration motor 108 is activated, causing the screening box 1 to vibrate. The irregularly shaped baffle 203 vibrates with the screening box 1, sliding left and right to prevent the raw material from clogging. The raw material falls through the feed inlet 206 onto the screening screen 102. Due to the vibration, the screening screen 102... The raw materials for glass fiber production are screened. Fine materials fall to the bottom of the screening box 1 and are collected from the fine material outlet 104. Coarse materials are collected from the coarse material outlet 103. The fan 304 is turned on. The dust generated during the screening of the raw materials for glass fiber production enters the filter box 3 from the air inlet 301. The dust is adsorbed by the filter plate 302. Due to the vibration of the screening box 1, the first filter frame 310 drives the filter plate 302 to move left and right. Due to the vibration effect, the dust adsorbed on the filter plate 302 is shaken off and falls into the dust collection box 309.
