Compared with the single mechanical stirring method of traditional equipment, the introduction of air enables the raw materials to be better dispersed during the mixing process, avoiding the stratification or aggregation of different materials due to density differences; the collection shell in the equipment is connected to the mixing chamber, and cooperates with the negative pressure environment to realize continuous material discharge and screening functions. By setting up multiple discharge ports, the timely discharge of smaller particles during the mixing process is ensured, avoiding the interference of large particles on the mixing process.

Description

Technical Field

[0001] The invention relates to the technical field of glass production, in particular to a mixing device for glass production. Background Art

[0002] Existing mixing equipment for glass production has many limitations in terms of mixing uniformity and screening raw material particle diameter, and fails to effectively meet the needs of modern production for efficient and refined mixing processes. Specifically, traditional mixing equipment usually relies on a single stirring design to mix raw materials through mechanical stirring or rotary stirring. Although such a design can complete basic mixing tasks, in the complex and diverse glass production process, especially in situations where high mixing uniformity is required, traditional equipment often shows unsatisfactory results.

[0003] First, the mixing method of traditional mixing equipment is mostly simple mechanical mixing, which cannot effectively ensure the uniform distribution of different materials. Since the types and particle sizes of glass raw materials are different, especially quartz sand, borax, boric acid and other raw materials often have different physical properties when mixed, such as density, particle shape, etc., which makes it easy for materials to aggregate and agglomerate during the mixing process. It is common that heavier or larger particles tend to sink during mixing, while lighter or finer particles may float on the upper layer, resulting in obvious differences in mixing uniformity, which ultimately affects the quality of the glass.

[0027] The collecting mechanism includes an air intake chamber 106, which is connected to the interior of a collecting shell 105. A separating and narrowing ring 108 is fixed on the inner wall of the air intake chamber 106. A centrifugal impeller 107 is rotatably arranged between the separating and narrowing ring 108 and the bottom surface of the inner wall of the air intake chamber 106.

[0028] The lower surface of the suction chamber 106 is fixedly mounted with a gearbox 113 through a gearbox bracket 114, the output shaft of the gearbox 113 is fixedly matched with the centrifugal impeller 107, the collection chamber 109 is fixedly connected with a funnel 110, the funnel 110 is fixedly connected with a discharge pipe 111, the input shaft of the gearbox 113 is fixedly mounted with an extended shaft 112, the extended shaft 112 extends to the outside of the discharge pipe 111, wherein the discharge pipe 111 and the funnel 110 are fixed on the support base plate 218.

The outer surface of the stirring chamber 101 is provided with a sleeve ring 211 at the bottom of the sliding sleeve, and the sleeve ring 211 is fixed on the sleeve ring bracket 210, and the sleeve ring bracket 210 is slidably mounted on two support slide bars 208, and the two support slide bars 208 are fixed on the electromagnet bracket 207, and the electromagnet bracket 207 is fixed on the stirring chamber 101, and the electromagnet bracket 207 is also fixed with an electromagnet 206 that cooperates with the sleeve ring bracket 210 and the sleeve ring 211 by magnetic force. A return spring 209 is arranged around each support slide bar 208, and the two ends of the return spring 209 are fixed to the bottom ends of the sleeve ring bracket 210 and the support slide bar 208, and are used to pull the sleeve ring bracket 210 and the sleeve ring 211 to slide downward on the support slide bar 208, and the sleeve ring 211 can be sleeved on the bottom pool 202, and is used to seal and connect the stirring chamber 101 and the bottom pool 202. A plurality of feeding pipes 117 communicating with the interior of the mixing chamber 101 are fixedly mounted on the top sealing plate 103 , and a material storage pool 116 is fixedly disposed at the top end of each feeding pipe 117 .

[0029] The working principle of a mixing device for glass production disclosed in the present invention is as follows: raw materials are poured into a storage pool 116 (the raw materials are mainly quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc., different raw materials are poured into different storage pools 116, and a shut-off valve plate is provided in the feeding pipe 117 to control the amount of raw materials falling into the stirring chamber 101).

[0030] After the required proportion of raw materials is poured into the mixing chamber 101, the driving motor 217 is started, and the output shaft of the driving motor 217 drives the driving gear 216 to rotate, and the driving gear 216 drives the driving toothed disc 215 to rotate, and the driving toothed disc 215 drives the transmission sleeve shaft 213 to rotate, and the rotation of the transmission sleeve shaft 213 drives the central gear 205 to rotate, and the rotation of the central gear 205 drives the stirring toothed disc 204 to rotate (only one stirring toothed disc 204 is working, and the others are idling, because idling does not have too much load, so the energy consumed is very small), the stirring toothed disc 204 drives the stirring part 203 to rotate, and the rotation of the stirring part 203 will stir the raw materials inside the mixing chamber 101, and will also crush some raw materials with larger diameters. During the stirring and mixing process, the raw materials will rotate inside the mixing chamber 101 (the bottom is the bottom pool 202), and at this time, some raw material particles with smaller diameters will float in the air inside the mixing chamber 101 (dust).

[0031] The rotation of the transmission sleeve shaft 213 will also drive the extension shaft 112 to rotate through the transmission belt 214. The rotation of the extension shaft 112 will drive the input shaft of the gearbox 113 to rotate, and the output shaft of the gearbox 113 will drive the centrifugal impeller 107 to rotate. The rotation of the centrifugal impeller 107 will inhale the air inside the suction chamber 106 and also drive the air to rotate. At this time, the air will be thrown into the collection chamber 109 through the throwing-out channel 115 under the action of centrifugal force (the gap between the collection chamber 109 and the suction chamber 106 is filled with multiple sections of arc-shaped sealing wooden plugs to facilitate cleaning of the inside of the funnel 110). Under the action of the centrifugal impeller 107, the interior of the suction chamber 106 is in a low-pressure environment. Since the suction chamber 106 is connected to the interior of the collecting shell 105, the interior of the collecting shell 105 is also in a low-pressure environment. Then, the interior of the mixing chamber 101 is in a low-pressure environment through the discharge port 102. Therefore, the raw material particles with a smaller diameter and mass rotating in the mixing chamber 101 will be sucked out to the outside of the mixing chamber 101 through the discharge port 102, thereby achieving mixing and screening. At the same time, since the interior of the mixing chamber 101 is in a low-pressure environment, the external air will be introduced into the interior of the mixing chamber 101 through the set air inlet pipe 104. At this time, the bottom of the air inlet pipe 104 will blow air to the raw materials in the mixing chamber 101, so that the raw materials are dispersed in the mixing chamber 101, and at the same time, they are discharged to the outside of the mixing chamber 101 through the negative pressure discharge port 102. Some raw material particles with larger diameters will remain in the stirring chamber 101 (different stirring parts 203 are used according to needs. If the stirring part 203 has the function of crushing the raw materials, the raw materials can be crushed to meet the diameter requirements. In general, the stirring part 203 only mixes and stirs the raw materials).

[0032] The raw material particles discharged through the discharge port 102 will follow the direction of the air flow through the collecting housing 105 into the suction chamber 106, then enter between the blades of the centrifugal impeller 107, and then be thrown into the collection chamber 109 under the action of centrifugal force, and then fall into the funnel 110, and then be discharged to the designated location through the discharge pipe 111. In this way, the raw materials can be mixed and processed continuously, and at the same time, the function of raw material diameter screening is possessed to ensure the quality of raw material mixing.

[0033] To replace a different stirring part 203, it is only necessary to rotate the star frame 201. Before rotating the star frame 201, it is necessary to start the electromagnet 206 to allow the electromagnet 206 to generate magnetic force to attract the ring 211 and the ring bracket 210, so that the ring 211 is separated from the bottom pool 202. At this time, the reset spring 209 is in a stretched state, and then the star frame 201 is rotated to rotate the corresponding stirring part 203 to a position coaxial with the stirring chamber 101. At this time, the electromagnet 206 is powered off, and the ring 211 will be sleeved on the outside of the bottom pool 202 under the action of its own gravity and the reset spring 209.
