Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz powder processing technology, and in particular to a raw material screening device for quartz powder processing. Background Technology
[0002] Quartz powder is a powder produced from pure quartz (natural quartz or fused quartz) through multiple processes including crushing, sorting, washing, acid treatment, high-temperature melting, medium crushing, fine grinding, grading, and iron removal, meeting the requirements for use. After the raw materials of quartz powder are crushed and ground, a raw material screening device is used to screen the raw materials to separate larger particles, which are then subjected to secondary grinding.
[0003] For example, utility model application number 20212242519.5 discloses a raw material screening device for quartz powder processing. By setting a push plate and a drive mechanism inside the shell, the push plate can be moved by the drive mechanism to directly push the screened particles out of the shell, which facilitates the cleaning of quartz particles, reduces the difficulty of cleaning, and avoids the leakage of quartz powder during manual cleaning, thus greatly improving the convenience of the device.
[0004] The above applications still have shortcomings:
[0005] The raw material screening device for this type of quartz powder processing requires an additional drive mechanism, such as a motor, to discharge the screened particles out of the shell. This not only increases the overall production cost, but also the vibration of the screen by the vibrating motor affects the operation of the drive mechanism, affects the discharge of particles, and increases the difficulty of cleaning.
[0006] To address this issue, a raw material screening device for quartz powder processing was designed. Utility Model Content
[0007] The main purpose of this invention is to provide a raw material screening device for quartz powder processing, so as to solve the related technical problems mentioned in the background art.
[0008] The objective of this utility model can be achieved by adopting the following technical solution:
[0009] A raw material screening device for quartz powder processing includes a housing. A support plate is vertically installed inside the housing. A screening cylinder is rotatably installed at the middle position of the support plate, and one end of the screening cylinder is rotatably connected to the inner side wall of the housing. A motor is installed on one side of the housing. A rotating shaft is fixed to the output shaft of the motor. Connecting rods are evenly arranged on the outer side of the rotating shaft. The screening cylinder is connected to the outer side of the rotating shaft through the connecting rods. A feeding assembly is provided on the other side of the housing. A cleaning assembly is provided on the inner top wall of the housing. An inclined plate 1 and a movable inclined plate 2 are respectively inclined on both sides of the support plate. A collection frame 1 and a collection frame 2 are slidably installed on both sides of the housing.
[0010] Preferably, the feeding assembly includes a feeding cylinder and a fixing rod. The feeding cylinder is located on one side of the housing and extends through and into the interior of the housing. A feeding hopper is installed at one end of the feeding cylinder. The fixing rod is located at one end of the rotating shaft and extends through the feeding cylinder to the inner wall of the feeding hopper. A spiral blade is sleeved on the outer side of the fixing rod. The bottom of the feeding cylinder is uniformly provided with material discharge ports.
[0011] Preferably, the cleaning assembly includes a fixing plate and bristles. The fixing plate is located on the inner top wall of the housing. Bristles are evenly arranged on the bottom of the fixing plate, and sleeves are evenly arranged on the top of the fixing plate. A sleeve rod is slidably installed inside the sleeve, and springs are sleeved on the outer side of the sleeve rod.
[0012] Preferably, a handle is provided on one side of the first collection box and one side of the second collection box, and a protective ring is provided on the outside of the handle.
[0013] Preferably, the screening cylinder is provided with bearing rings at both ends, and the screening cylinder is a conical cylinder.
[0014] Preferably, the bottom of the housing is provided with a support block, and the bottom of the support block is provided with anti-slip texture.
[0015] The beneficial effects of this utility model are as follows:
[0016] This utility model provides a raw material screening device for quartz powder processing. Through the coordinated use of a shell, a support plate, a screening cylinder, a motor, a rotating shaft, a connecting rod, an inclined plate one, an inclined plate two, a collection frame one, and a collection frame two, the screened particles can be collected into the collection frame two during the rotation screening of quartz powder raw materials. No additional drive mechanism is needed to separate the particles, achieving higher energy efficiency and thus improving the practicality of the raw material screening device for quartz powder processing.
[0017] By using the feed hopper, feed cylinder, fixed rod, spiral blade and discharge port in combination, the quartz powder raw material is pushed into the screening cylinder by the spiral blade to avoid clogging of the quartz powder raw material. The discharge port ensures that the quartz powder raw material is evenly fed into the screening cylinder, avoiding excessive material conveying and affecting the screening accuracy, thereby improving the screening accuracy of the screening device for quartz powder processing raw material screening.
[0018] By using a combination of a fixed plate, brush bristles, sleeve, rod, and spring, the sieve cylinder rotates to the top where it filters the quartz powder raw material. This allows the brush bristles to comb through the mesh of the sieve cylinder, causing the raw material particles that are blocked in the mesh to return to the inside of the sieve cylinder for further screening. This avoids clogging of the mesh during screening and improves screening efficiency. Attached Figure Description
