Description

Technical Field

[0001] The invention relates to the technical field of glass production, in particular to a raw material crushing and impurity removal device for glass production. Background Art

[0002] Most of the existing glass raw material crushing and impurity removal devices adopt a relatively simple single-stage crushing structure, and usually process the glass raw materials by a single impact or grinding method. The main problem of this type of equipment is that its crushing effect is limited, especially when processing large particles of raw materials. Since the crushing process mainly relies on a one-time impact or a single mechanical force, larger particles cannot be fully crushed in a short time, resulting in the need for repeated operations. During the multiple crushing processes, some raw material dust will leak, thereby affecting the ambient air quality. In addition, traditional crushing equipment is prone to generate a large amount of dust during operation. This dust is usually formed by the peeling or decomposition of the surface of the material particles during high-speed impact or grinding. Since most existing equipment lacks an effective dust collection system, dust can easily spread inside and outside the crushing area. This not only causes serious pollution to the operating environment, but also poses a potential threat to the health of workers and increases the cleaning and maintenance costs of the production site.

[0003] More importantly, the spread of this dust will directly affect the utilization rate of raw materials. Since dust often contains fine raw material particles, these particles are easily lost if they are not fully collected, resulting in a waste of raw materials. At the same time, if the dust is not handled in time, it may also affect the quality of products in subsequent processes, and even in some cases cause increased wear of equipment, further shortening the service life of the equipment.

The end of the sliding inclined tube 114 connected to the separation chamber 105 is at a high position, and the end of the sliding inclined tube 114 at a low position is fixedly connected to a recovery pipe 116.

[0023] A cleaning collection plate 120 is fixedly connected to the top of the first collecting chamber 119 and the second collecting chamber 126, and a cleaning scraper 125 is coaxially rotatably arranged in the cleaning collection plate 120. A sealing cover plate 121 is fixedly sealed on the cleaning collection plate 120. The sealing cover plate 121 and the cleaning collection plate 120 form a cavity, and the cleaning scraper 125 is rotatably arranged in the cavity. A circular through hole is opened at the position where the sealing cover plate 121 is aligned with the first collecting chamber 119, and a filter screen 124 is fixedly arranged in the circular through hole. The filter screen 124 is connected to the inner diameter of the first collecting chamber 119, and the filter screen 124 is coaxially positioned with the first collecting chamber 119, and the lower surface of the filter screen 124 is slidably matched with the cleaning scraper 125. A cleaning motor 123 is fixedly mounted on the sealing cover plate 121, and the output shaft of the cleaning motor 123 is fixed to the cleaning scraper 125. A negative pressure air pump 122 is also fixedly mounted on the sealing cover plate 121, and a filter screen 124 is arranged on the air inlet of the negative pressure air pump 122. A discharge nozzle 129 is fixedly connected to the bottom of the discharge sedimentation pool 127, and a discharge screw 128 is rotatably mounted on the discharge nozzle 129 and the bottom of the inner wall of the discharge sedimentation pool 127. The discharge screw 128 is driven to rotate by a second gearbox 130 fixed to the outer wall of the discharge sedimentation pool 127; the bottom end of the rotating shaft 106 is connected to the input shaft of the second gearbox 130 through a second transmission belt 133. A driving disk 131 is fixed to the bottom end of the rotating shaft 106, and a first gearbox 117 is fixed to the bottom end of the recovery pipe 116. The output shaft of the first gearbox 117 is fixedly matched with the recovery screw 115. The input shaft of the first gearbox 117 is connected to the bottom end of the rotating shaft 106 through a first transmission belt 132. A driving motor 135 is also fixedly installed on the base 137. The output shaft of the driving motor 135 is connected to the driving disk 131 through a third transmission belt 134.

[0024] The working principle of the raw material crushing and impurity removal device for glass production disclosed in the present invention is as follows: when in use, the driving motor 135 is started to pour the raw materials for producing glass into the top entrance of the recovery pipe 116. Since there is a recovery screw 115 inside the recovery pipe 116, this part of the raw materials will fall into the feed inclined tube 118, and then slide along the feed inclined tube 118 to the feed port 112. At this time, these raw materials will pass through the feed port 112 and enter the first crushing chamber 109. At this time, these raw materials will fall onto the first rotating disk 102 inside the first crushing chamber 109, and then the rotation of the first rotating disk 102 will drive these raw materials to rotate. The raw materials will move radially outward along the first rotating disk 102 under the action of centrifugal force. At this time, these raw materials will fly toward the inner wall of the first crushing chamber 109, thereby colliding with the inner wall of the first crushing chamber 109, so that the particles with larger diameters in the raw materials are broken. At this time, these raw materials will move along the first The inner wall of the crushing chamber 109 slides down (the inner walls of the first crushing chamber 109, the second crushing chamber 110, and the third crushing chamber 111 are all funnel-shaped and connected end to end), and then enters the second rotating disk 103 inside the second crushing chamber 110, aligns and performs another impact crushing, and then enters the third rotating disk 104 inside the third crushing chamber 111 for another impact crushing. Since the diameters of the first rotating disk 102, the second rotating disk 103, and the third rotating disk 104 increase successively, the rotation radius of the raw material increases. Since the first rotating disk 102, the second rotating disk 103, and the third rotating disk 104 are all fixed to the rotating shaft 106 and driven to rotate by the rotating shaft 106, their rotation speeds are the same, which also causes the centrifugal force on the raw materials on the first rotating disk 102, the second rotating disk 103, and the third rotating disk 104 to increase successively, thereby achieving gradual crushing.

[0025] The negative pressure air pump 122 is started simultaneously with the driving motor 135; the output shaft of the driving motor 135 drives the driving disk 131 to rotate via the third transmission belt 134, the driving disk 131 drives the rotating shaft 106 to rotate (the two are fixed), the rotating shaft 106 also drives the input shaft of the first gearbox 117 to rotate via the first transmission belt 132, and the rotating shaft 106 also drives the input shaft of the second gearbox 130 to rotate via the second transmission belt 133. When the negative pressure air pump 122 is started, it will absorb the air inside the first collecting chamber 119 through the filter screen 124, so that negative pressure is generated inside the first collecting chamber 119 (including the discharge sedimentation pool 127 and the second collecting chamber 126 connected to the first collecting chamber 119. At the beginning, raw materials are arranged at the bottom of the discharge sedimentation pool 127. This part of the raw materials will bury the discharge screw 128, thereby blocking the discharge nozzle 129). Since the separation port 108 is connected to the interior of the first collecting chamber 119, the interior of the separation chamber 105 is in a negative pressure environment. At the same time, the third crushing chamber 111, the second crushing chamber 110, the first crushing chamber 109, and the feeding inclined tube 118 connected to the separation chamber 105 are all in a negative pressure environment. At this time, the external air will also be sucked in through the top of the recovery pipe 116, thereby preventing some raw material dust from leaking out before entering the feeding inclined tube 118.

[0026] The raw materials crushed from the third crushing chamber 111 will fall into the separation chamber 105 through the discharge port 113 (a striking crushing blade 138 can be provided during the falling process for further crushing), and some of the raw material dust with a smaller particle diameter will follow the airflow into the separation port 108, and then enter the first collection chamber 119. Most of the dust entering the first collection chamber 119 will be adsorbed on the surface of the filter screen 124 under the action of negative pressure, and some will directly fall into the discharge sedimentation pool 127, so it is necessary to start the cleaning motor 123, and the output shaft of the cleaning motor 123 drives the cleaning scraper 125 to rotate, and the cleaning scraper 125 rotates to scrape off the raw material dust attached to the surface of the filter screen 124, and then discharge it to the second collection chamber 126. Since there is no pressure difference at the second collection chamber 126, these raw material dusts will fall into the discharge sedimentation pool 127 under the action of gravity. Then it is discharged through the discharge screw 128, and the discharge screw 128 is driven by the second gearbox 130.

[0027] The raw materials crushed from the third crushing chamber 111 will fall into the separation chamber 105 through the discharge port 113, among which some raw material particles with larger diameters will not follow the airflow into the separation port 108, but will fall directly to the bottom of the separation chamber 105 under the action of gravity, and then fall into the sliding inclined tube 114, and slide down the sliding inclined tube 114 to the bottom of the recovery pipe 116. At this time, the rotating recovery pipe 116 (the recovery pipe 116 is driven by the first gearbox 117) will convey this part of the raw material particles to the top, so as to re-enter the feed inclined tube 118 for re-crushing, while those impurities with larger diameters that have not been crushed will continue to enter the circulation and cannot enter the first collection chamber 119 through the separation port 108.
