Detailed Implementation

[0022] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 , Figure 2 As shown, this utility model discloses an embodiment of a V-type mixer used in optical glass production. The mixer 1 consists of a V-shaped mixing chamber 2, a support 3, a stirring shaft 4, an iron removal device 5, a motor 6, and a transmission belt 7. The V-shaped mixing chamber 2 includes a lower main mixing chamber and an upper V-shaped inlet 8 and a cleaning port 9. The inlet 8 is equipped with an inlet cover 11, and the cleaning port 9 is equipped with a cleaning port cover 12. The cleaning port cover 12 can be opened and is used to clean the adhering substances on one side of the inner wall of the cleaning port 9 when the mixer has been used for a long time or when the mixing grade is changed. The bottom of the main mixing chamber is equipped with an outlet 10 and a butterfly valve 13. The lower end of the outlet 10 is equipped with an iron removal device 5, which consists of a PP material outlet pipe and magnetic rods 14 arranged on the outlet pipe. The magnetic rods 14 can be arranged in one layer or multiple layers. The support frame 3 consists of two symmetrical vertical supports. The V-shaped mixing chamber 2 is welded to the middle of the stirring shaft 4, and both ends of the stirring shaft 4 are horizontally fixed to the support frame 3 via bearings. The motor 6 is mounted on one vertical support, and the controller 16 is mounted on the other vertical support. The controller 16 is electrically connected to the motor 6 and the heating baffle 15. The V-shaped mixing chamber 2 is made of stainless steel, and a PVC lining is added as needed based on the chemical properties of the raw materials to be mixed. The heating device consists of pairs of heating baffles 15 arranged on both sides of the V-shaped mixing chamber 2. There are two pairs of heating baffles 15, located in the middle and lower part of the V-shaped mixing chamber 2. Depending on the needs, there may be one or more pairs of heating baffles 15. Each pair of heating baffles 15 is symmetrically arranged inside the V-shaped mixing chamber 2, forming an angle of 5 to 45 degrees with the inner wall of the V-shaped mixing chamber 2. The heating baffles 15 have electrodes on the outside of the V-shaped mixing chamber 2 and heating resistance wires installed inside, which can be directly heated by electricity. A soft gasket for sealing is installed between the feed inlet 8 and the feed inlet cover 11, between the cleaning port 9 and the cleaning port cover 12, and between the discharge port 10 and the butterfly valve 13. The gasket can be made of materials such as rubber.

[0024] Before using the V-type mixer provided by this utility model, open the feed inlet cover 11, weigh the required raw materials according to the required type and weight, and put them into the V-type mixing bin 2 through the feed inlet 8, then close the feed inlet cover 11. After confirming that there are no gaps at the interfaces of the mixer, start the motor 6 and the heating baffle 15 through the controller 16. Driven by the motor 6 and the transmission belt 7, the stirring shaft 4 starts to rotate, and the entire V-type mixing bin 2 will also rotate and flip to mix the materials. At the same time, the heating baffle 15 starts to be heated by a constant current power supply, usually using a current of about 10~100A. After the mixing is completed, open the butterfly valve 13 of the discharge port 10, and the batch material flows out of the V-type mixing bin 2 under the action of gravity after passing through the iron removal device 5. When the mixer has been used for a long time or when cleaning the mixer after changing its grade, the cleaning port cover 12 of the cleaning port 9 can be opened to clean or wash the attached substances on the inner wall of the hopper on one side of the cleaning port 9. The inner wall of the feeding end can be cleaned or washed through the feeding port 8, and the inner wall of the discharging end can be cleaned or washed through the discharging port 10. After the mixer is cleaned, the heating baffle 15 in the mixer can be activated through the controller 16 to dry the mixer.
