Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a stable water adding device for a mixer. Background Art

[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. The mixer is generally provided with a water adding device. During the material mixing process, water is added to the materials through the water adding device.

[0003] At present, some domestic models of mixers are provided with a water inlet on the mixer body, and water is added obliquely into the mixer through the water inlet. The water flow is sprayed obliquely into the cylinder from the water inlet and then sprayed in an umbrella shape. After the water nozzle is atomized, the umbrella-shaped spraying effect is not good. The umbrella-shaped spraying makes the outer circle of the mixer have more moisture and the inner circle have less moisture. The moisture content of the mixture in the mixer is uneven, and the moisture difference of the mixture is too large, which makes the materials not uniform when mixed.

[0004] If the mixed materials used in glass production, such as soda ash, aluminum hydroxide and other easily fusible materials used in glass production, are not mixed evenly, the problem of too fast melting speed will occur during production; and if the refractory materials such as silica sand and dolomite are not mixed evenly, it will be difficult to melt or even have incomplete melting problems. If the materials melt too fast or not completely, the uniformity of the glass will be destroyed, resulting in defects such as stones, inclusions, crystallization, streaks, bubbles, etc. in the glass production process. Therefore, it is urgent to propose a mixer stable water adding device to solve the problem of uneven moisture content of the mixed materials in the mixer. Summary of the invention

[0005] The utility model aims to provide a stable water adding device for a mixer to solve the problem of uneven water content of mixed materials in the mixer.

[0006] In order to achieve the above objectives, the technical solution of the utility model is:

[0007] A stable water adding device for a mixer comprises a water inlet located on a mixer body, and also comprises a main pipeline located on a side wall of a mixer cylinder, one end of the main pipeline is connected to the water inlet, a plurality of branch pipes are evenly arranged on the main pipeline, each branch pipe comprises an arc section and a horizontal section, the horizontal section is parallel to the bottom surface of the mixer cylinder, a plurality of water outlet pipes are arranged at intervals on each horizontal section, each water outlet pipe is perpendicular to the horizontal section, and water flows vertically from the end of the water outlet pipe to the material inside the mixer.

[0008] Furthermore, the main pipeline is arranged transversely along the side wall of the mixer cylinder, and the length of the main pipeline is 1 / 3-1 / 2 of the circumferential length of the mixer cylinder.

[0009] Furthermore, the main pipeline is located above the rake arm for stirring materials in the mixer.

[0010] Furthermore, the plurality of branch pipes have the same height, and each branch pipe comprises an arc section and a horizontal section which are integrally formed, the starting end of the arc section is connected to the main pipeline, and the end of the arc section (21) is connected to the horizontal section, and the plurality of horizontal sections are on the same horizontal plane.

[0011] Furthermore, the mixer barrel is cylindrical, and the extension lines of the ends of the multiple horizontal sections intersect at one point inside the cylindrical barrel.

[0012] Furthermore, three water outlet pipes are arranged at intervals on the branch pipe, and the horizontal distances between the three water outlet pipes and the side wall of the mixer cylinder are 150 mm, 250 mm and 400 mm respectively.

[0013] The beneficial effects of the utility model are:

[0014] 1. In the prior art, water is added obliquely toward the material in the mixer through the water inlet on the mixer body. The water flows obliquely from the water inlet into the interior of the cylinder and then sprays in an umbrella shape. The umbrella-shaped spraying makes the outer circle have more moisture and the inner circle have less moisture, which makes the moisture in the material uneven and affects the use of the material. The utility model arranges a horizontal section pipeline parallel to the bottom of the mixer cylinder in the mixer, and then arranges a water outlet pipe perpendicular to the horizontal section pipeline. Water flows vertically into the material through the water outlet pipe, avoiding the umbrella-shaped spraying during oblique water discharge, thereby avoiding the problem of uneven moisture in the material due to the outer circle of the mixer having more moisture and the inner circle having less moisture.

[0015] 2. The utility model sets a horizontal section pipeline parallel to the bottom of the mixer cylinder in the mixer, and sets a plurality of vertical water outlet pipes at intervals on the horizontal pipeline, so that there is a water outlet pipe at different distances from the side wall of the cylinder to add water to the material, which is beneficial to the uniformity of the moisture in the material.

[0016] 3. Each branch pipe of the utility model includes an arc-shaped water flow channel, which can buffer the flow rate of the water flow, which is beneficial to the stability of the water flow in the mixer, and further conducive to achieving the uniformity of the moisture content of the materials in the mixer.

Each branch pipe 2 includes an arc segment 21 and a horizontal segment 22 formed in one piece, and the arc segment 21 can buffer the flow rate of the water flow, making the water flow more stable and uniform. The starting end of the arc segment 21 is connected to the main pipe 1, and the end of the arc segment 21 is connected to the starting point of the horizontal segment 22.
