Description

Technical Field

[0001] The utility model belongs to the technical field of water glass production, and in particular relates to a melt cooling and molding device for water glass production. Background Art

[0002] The production of water glass includes two methods: dry method and wet method. The dry method usually involves evenly mixing soda ash and silica sand in a certain proportion, and then melting them at high temperature. The molten material is then cooled by water quenching to form glass material, which is then put into a dissolving tank while hot, and then steam is introduced to heat and dissolve it. Finally, the water glass is produced through sedimentation and concentration.

[0003] When the existing cooling device is cooling, the molten body is in a relatively static state with the cooling water after entering the cooling water. During the heat exchange process, the temperature of the cooling water in direct contact with the molten body is high, and the temperature of the cooling water at a distance is low, that is, the temperature gradient of the cooling water is large, resulting in low heat exchange efficiency and poor cooling effect.

[0015] The beneficial effects of the utility model are:

[0016] 1. The utility model utilizes stirring blades to drive the melt to move in the cooling pool, so that the melt can fully contact with cooling water, thereby enabling the melt to be fully cooled, accelerating the cooling speed of the melt and improving production efficiency.

[0022] The present application is described in further detail below. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-2As shown, a molten body cooling and molding device for water glass production includes a cooling pool 1, the bottom of the cooling pool 1 is a semicircular arc structure, and the bottom of the semicircular arc structure of the cooling pool 1 is provided with an opening, a filter screen 2 is fixed at the opening, and the filter screen 2 is a semicircular arc structure.

[0025] A rotating shaft 5 is rotatably provided on the cooling pool 1, and the rotating shaft 5 is placed horizontally. A driving motor 6 is fixed on the outer wall of the cooling pool 1, and the output shaft end of the driving motor 6 is fixedly connected to the rotating shaft 5 or indirectly connected to the rotating shaft 5 through a reducer. A plurality of stirring blades 7 are fixed on the rotating shaft 5 along its circumference, and the maximum rotation radius of the stirring blade 7 is the same as the inner wall radius of the filter screen 2, that is, the end of the stirring blade 7 away from the rotating shaft 5 contacts the inner wall of the filter screen 2.

[0026] A cooling pool 3 is fixed at the bottom of the cooling pool 1 , and a conveyor 4 for taking the water glass away from the cooling pool 3 is arranged in the cooling pool 3 .

[0027] It should be noted that when the molten body enters the cooling pool 1, it is cooled by the cooling water (not limited to water, it can be other cooling bodies) in the cooling pool 1, and the molten body moves downward under the action of gravity until it moves to the bottom of the cooling pool 1, and the molten body accumulates above the filter screen 2.

[0028] As the molten body falls, it exchanges heat with the cooling water. At the same time, the driving motor 6 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the stirring blade 7 to rotate. The stirring blade pushes the accumulated molten body to move, and when the stirring blade rotates upward, the molten body is lifted up, so that the molten body is away from the filter screen 2.

[0029] The stirring action of the stirring blade 7 on the melt makes the melt come into full contact with the cooling water, so that the melt can be well and evenly cooled. When the melt is cooled and forms small particles, they fall onto the filter screen 2. The small particles of water glass that meet the screening criteria of the filter screen 2 pass through the filter screen 2, while the large particles of water glass continue to be stirred by the stirring blade 7 until they meet the screening criteria of the filter screen 2.

[0030] The water glass passing through the filter screen 2 falls onto the conveyor 4 and is then transported to the outside of the cooling pool 3 by the conveyor 4 .

[0031] The rotation speed of the stirring blade 7 is 10 r / min. The rotation speed of the stirring blade 7 should not be too fast or too slow. If it is too fast, the burden on the driving motor 6 will be too heavy, and if it is too slow, the efficiency of heat exchange between the melt and the cooling water will be reduced.

[0032] Furthermore, the cooling pool 3 further includes a first portion 8 located at the bottom of the cooling pool 1 and a second portion 9 located at the side of the cooling pool 1, and the first portion 8 and the second portion 9 are L-shaped structures. The height of the second portion 9 is the same as that of the cooling pool 1, so that the liquid height in the cooling pool 1 can be maintained at a higher position.

[0033] Furthermore, the conveyor 4 has a first section 10, a second section 11 and a third section 12. The first section 10 and the third section 12 are in horizontal directions and the height of the third section 12 is higher than that of the first section 10. The second section 11 is inclined.

[0034] The height of the third section 12 is higher than the height of the second section 9 .

[0035] It should be noted that the second section 11 of the conveyor 4 lifts the water glass upward, and the water glass is cooled again during the lifting process.

[0036] Furthermore, the conveyor 4 includes a frame and a conveyor belt, and a plurality of scraper strips 13 for assisting conveying are fixedly arranged on the conveyor belt. The scraper strips 13 can smoothly carry the water glass to the third section 12, thereby solving the problem of water glass slipping during conveying. The width of the conveyor belt can be set to be greater than the width of the filter screen 2, so as to reduce the situation that the water glass falls from the conveyor belt into the cooling pool 3.

[0037] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
