Abstract
Description
Technical Field
[0001] The utility model relates to the technical field related to methyltrimethoxysilane production equipment, in particular to a reaction tower for methyltrimethoxysilane production. Background Art
[0002] Methyltrimethoxysilane is typically produced through an alcoholysis reaction between methylchlorosilane and methanol in the presence of a catalyst. Under the action of the catalyst, the chlorine atoms in methylchlorosilane are replaced by methoxy groups in methanol, producing methyltrimethoxysilane and hydrogen chloride. During the reaction, a temperature control system regulates heating and cooling equipment to maintain the reaction temperature within the optimal range, promoting the reaction and preventing side reactions. A pressure control system regulates the pressure within the reaction tower to ensure the reaction proceeds at an appropriate pressure, thereby improving reaction rate and product purity. A reaction tower typically consists of a tower body, inlet and outlet piping, a stirring device, a temperature control system, and a pressure control system.
[0003] In the prior art, the reaction tower is fed through a feeding pipe. The material is introduced into the reaction tower through the feeding pipe and accumulated at the same position in the tower, resulting in uneven distribution of the material. In the subsequent reaction process, the local concentration of the material is too high or too low, which leads to uneven reaction. To this end, we propose a reaction tower for the production of methyltrimethoxysilane. Utility Model Content
[0004] In order to solve the defects of the prior art, the utility model provides a reaction tower for producing methyltrimethoxysilane.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0006] The utility model discloses a reaction tower for producing methyltrimethoxysilane, comprising a tower body, a feed pipe rotatably mounted on the upper end of the tower body, a discharge pipe mounted on the lower end of the tower body and a control valve mounted thereon, a barrel arranged in the tower body, the barrel being connected to the feed pipe, the upper end of the barrel being sleeved on the lower end of the feed pipe and being able to slide up and down, guide rods being fixedly mounted on both sides of the lower end of the feed pipe, the upper end of the guide rod passing through the barrel, a first spring being sleeved on the guide rod, the two ends of the first spring being respectively fixedly connected to the barrel and the feed pipe, the bottom of the barrel being provided with evenly distributed leakage grooves, the bottom end of the barrel side wall being provided with evenly distributed outlets, a driving mechanism connected to the discharge pipe being mounted on the tower body and the driving mechanism being able to drive the discharge pipe to rotate, and a sealing plug being provided at the upper end of the discharge pipe.
[0007] As an optimal technical solution of the present invention, the driving mechanism includes a ring gear, which is fixedly connected to the top of the discharge pipe. A motor is fixedly installed on the tower body, and a gear is fixedly installed on the output shaft end of the motor, and the gear is meshed with the ring gear.

[0009] As a preferred technical solution of the present invention, a plurality of inclined blocks distributed in a circular array are fixedly installed in the tower body, and the inclined blocks are arranged in cooperation with the round rods.
[0010] As an optimal technical solution of the present invention, the contact surface between the sealing plug and the feed pipe is provided with vertically arranged anti-slip grooves, a spline sleeve is fixedly installed on the bottom of the sealing plug, a support frame is fixedly installed on the lower end of the tower body, a vertical shaft is rotatably installed on the support frame, and a plurality of blades are fixedly connected to the vertical shaft.

[0013] 1. This reaction tower for the production of methyltrimethoxysilane drives the feed pipe to rotate, and the feed pipe can drive the barrel to rotate synchronously. Under the action of centrifugal force, the material in the barrel moves outward and can be discharged from the outlet distributed on the outside, so that the material can be thrown out from the outlet and scattered to other places besides directly below the barrel.

The round rod separates from the inclined block, and the first spring drives the barrel to fall. During the rotation of the barrel, the round rod cooperates with the multiple inclined blocks, thereby causing the barrel to vibrate, which can shake off the materials at the trough and outlet, making it less likely to be blocked.

DETAILED DESCRIPTION
[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0022] Example 1:
[0023] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a reaction tower for the production of methyltrimethoxysilane, comprising a tower body 1, a feed pipe 2 being rotatably mounted on the upper end of the tower body 1, a discharge pipe 3 being mounted on the lower end of the tower body 1 and a control valve being mounted thereon, a barrel 17 being arranged in the tower body 1, the barrel 17 being connected to the feed pipe 2, the upper end of the barrel 17 being sleeved on the lower end of the feed pipe 2 and being able to slide up and down, guide rods 4 being fixedly mounted on both sides of the lower end of the feed pipe 2, the upper end of the guide rod 4 passing through the barrel 17, a first spring 5 being sleeved on the guide rod 4, the two ends of the first spring 5 being respectively fixedly connected to the barrel 17 and the feed pipe 2, a uniformly distributed leakage groove 6 being provided at the bottom of the barrel 17, a uniformly distributed outlet 7 being provided at the bottom end of the side wall of the barrel 17, a driving mechanism connected to the discharge pipe 3 being mounted on the tower body 1 and the driving mechanism being able to drive the discharge pipe 3 to rotate, and a sealing plug 8 being provided at the upper end of the discharge pipe 3.
[0024] Among them, the driving mechanism includes a ring gear 9, which is fixedly connected to the top of the discharge pipe 3, and a motor 10 is fixedly installed on the tower body 1. A gear 11 is fixedly installed on the output shaft end of the motor 10, and the gear 11 is meshed with the ring gear 9.
[0025] The sealing plug 8 is taken out and material is added through the feed pipe 2. The material falls into the barrel 17 through the feed pipe 2. The material can slowly fall into the tower body 1 through the leakage groove 6. At the same time, the gear 11 is driven to rotate by the motor 10, and the gear 11 drives the ring gear 9 to rotate, which can drive the ring gear 9 and the feed pipe 2 to rotate synchronously. The feed pipe 2 can drive the barrel 17 to rotate synchronously. Under the action of centrifugal force, the material in the barrel 17 moves outward and can be discharged from the outlet 7 distributed on the outside, so that the material can be thrown out from the outlet 7, and the material can be scattered to other places other than directly below the barrel 17. By changing the speed of the motor 10, the throwing speed of the material can be increased or decreased, so that the material can be thrown out at different distances, so that the material can be scattered at different positions in the tower body 1, making the material distribution more uniform, and the subsequent reaction will also be more uniform and sufficient.
[0026] Example 2:
[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, as another preferred embodiment of the present invention, the difference from Example 1 is that a round rod 12 is passed through the barrel 17, one end of the round rod 12 is fixedly connected to a magnet 13, a second spring 14 is sleeved on the round rod 12, and the two ends of the second spring 14 are respectively fixedly connected to the barrel 17 and the magnet 13. An electromagnet 15 is fixedly installed in the barrel 17 and is located on one side of the magnet 13. A plurality of inclined blocks 16 distributed in a circular array are fixedly installed in the tower body 1, and the inclined blocks 16 are arranged in conjunction with the round rod 12.
[0028] Under normal circumstances, the end of the round rod 12 will not contact the multiple inclined blocks 16. When the trough 6 and the outlet 7 are blocked by materials and the discharge is not smooth, the electromagnet 15 is energized and applies a repulsive force to the magnetic block 13, so that the round rod 12 can move outward and the second spring 14 is compressed. One end of the round rod 12 can contact the multiple inclined blocks 16. The motor 10 works and drives the barrel 17 to rotate. The round rod 12 rotates synchronously. The round rod 12 contacts the inclined block 16 and rises a certain distance under the action of the inclined surface, so that the barrel 17 can move upward synchronously. The first spring 5 is compressed, and the round rod 12 separates from the inclined block 16. The first spring 5 drives the barrel 17 to fall. During the rotation of the barrel 17, the round rod 12 cooperates with the multiple inclined blocks 16, so that the barrel 17 produces a shaking motion, which can shake off the materials at the trough 6 and the outlet 7, making it less likely to be blocked.
[0029] The contact surfaces of the sealing plug 8 and the feed pipe 2 are both provided with vertical anti-slip grooves. A spline sleeve 18 is fixedly mounted on the bottom of the sealing plug 8. A support frame 19 is fixedly mounted on the lower end of the tower body 1. A vertical shaft 20 is rotatably mounted on the support frame 19, and a plurality of blades 21 are fixedly connected to the vertical shaft 20. The lower end of the spline sleeve 18 can be sleeved on the upper end of the vertical shaft 20, and the spline sleeve 18 and the upper end of the vertical shaft 20 are splined.
[0030] After the feeding is completed, the sealing plug 8 is inserted into the feeding pipe 2. There is sufficient friction between the sealing plug 8 and the feeding pipe 2. The motor 10 works and drives the feeding pipe 2 to rotate. The feeding pipe 2 and the sealing plug 8 rotate synchronously. The spline sleeve 18 rotates and drives the vertical shaft 20 to rotate. The multiple blades 21 on the vertical shaft 20 rotate and stir and mix the solution. The stirring and feeding share the same power, saving costs.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
