DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a purification device for producing methyltrimethoxysilane, comprising a distillation tank 1 and a side frame 2 fixedly connected to the side of the distillation tank 1, a filter assembly 3 is movably connected to the surface of the side frame 2, the distillation tank 1 and the filter assembly 3 are movably connected, and a neutralizing liquid tank 5 is connected to the side of the distillation tank 1 through a pipeline; an adjusting rod 6 is installed on the top of the distillation tank 1, and an end of the adjusting rod 6 away from the distillation tank 1 is fixedly connected to an exhaust gas recovery tank 4, a sliding seat 7 is slidably connected to the surface of the adjusting rod 6, and a sealing sleeve 8 is fixedly connected to the side of the sliding seat 7 for sealing the contact position of the upper and lower ends of the filter assembly 3; a reset spring 9 is arranged on the top of the distillation tank 1, and one end of the reset spring 9 is fixedly connected to the sliding seat 7. Due to the adjustment of the sliding seat 7, the following are used:

[0022] like Figure 4 As shown, a positioning ring 201 is fixedly connected to the surface of the side frame 2, and the positioning ring 201 is located below the filter assembly 3. By setting the positioning ring 201, it is convenient to position the filter assembly 3 and avoid position deviation, which will cause errors in the docking of the filter box of the filter assembly 3 with the distillation tank 1 and the exhaust gas recovery tank 4, affecting the overall usage.

[0023] like Figure 2 As shown, a filter net 301 is fixedly connected to the inner wall of the filter assembly 3, and a limit ring 302 is provided on the surface of the filter assembly 3. The limit ring 302 is located on the side of the sealing sleeve 8. By providing the limit ring 302, the position of the sealing sleeve 8 in sealing use is limited to avoid excessive displacement during use, resulting in exposure of the connection part and affecting the use effect.

[0024] like Figure 3As shown, the surface of the adjusting rod 6 is fixedly connected to a limiting member 601, and the limiting member 601 is located between the two sliding seats 7. By setting the limiting member 601, the movement range of the sliding seat 7 is limited to avoid contact between the two sliding seats 7 and delay of the normal sealing effect.

[0025] like Figure 1 As shown, a fixed valve 101 is fixedly connected to the side of the distillation tank 1, and a support frame 102 is fixedly connected to the bottom of the distillation tank 1. By setting the support frame 102, it is convenient to support the bottom to avoid contact between the bottom and the ground, thereby avoiding corrosion and extending the service life of the equipment.

[0026] like Figure 3 As shown, a pulling rod 701 is fixedly connected to the side of the sliding seat 7, and the surface of the pulling rod 701 is provided with anti-skid patterns. The anti-skid patterns on the surface of the pulling rod 701 facilitate the staff to pull the pulling rod 701, making it more convenient to pull up and down, thereby facilitating use.

[0027] like Figure 4 As shown, the surface of the side frame 2 is connected to a limiting threaded sleeve 10 through a threaded connection. The limiting threaded sleeve 10 is located above the filter assembly 3. By setting the limiting threaded sleeve 10, the position of the filter assembly 3 is limited to avoid separation during rotation and affect the overall usage.

[0028] The working principle of the utility model is as follows: when in use, by connecting the distillation tank 1 to the neutralization liquid tank 5 and filling a small amount of water in the neutralization liquid tank 5, the HCL gas generated in the distillation process can be dissolved in the water, the impurity gas can be filtered out, and the effect of further purification can be achieved. When one of the filter boxes of the filter assembly 3 is in use, the staff pulls the sliding seat 7, and the pulled sliding seat 7 moves up and down on the surface of the adjusting rod 6 for use. When replacing with a clean filter box, the staff loosens the sliding seat 7, and under the telescopic movement of the reset spring 9, drives the two sealing sleeves 8 to respectively cover the upper and lower parts of the filter assembly 3, thereby achieving the sealing degree of the contact position between the distillation tank 1 and the filter assembly 3 and sealing the waste gas recovery tank 4 and the filter assembly 3. When the staff finishes using it, by rotating the limiting threaded sleeve 10, the rotating limiting threaded sleeve 10 is threadedly connected with the side frame 2, so that the staff can remove the limiting threaded sleeve 10 and disassemble and clean the filter assembly 3 for use.

[0029] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
