Description

Technical Field

[0001] This utility model relates to the technical field of equipment for the production and processing of organosilicon, specifically to an organosilicon monomer distillation device. Background Technology

[0002] Organosilicon, also known as organosilicon compounds, is a class of organic compounds containing carbon-silicon bonds. Organosilicon can be divided into two categories: linear organosilicon and cyclic organosilicon. Linear organosilicon mainly has a chain-like molecular structure, such as polysiloxanes; cyclic organosilicon has a cyclic structure composed of silicon and carbon atoms, such as cyclic siloxanes. Organosilicon has many important industrial applications. For example, organosilicon materials with properties such as high temperature resistance, chemical corrosion resistance, and thermal insulation are widely used in aerospace, automotive, construction, and electronics industries. In addition, organosilicon is commonly used as a lubricant, adhesive, sealant, and waterproofing agent. Organosilicon also has rich biological applications, such as in pharmaceuticals, biomedicine, and biotechnology.

[0003] Currently, in organosilicon production, the exhaust gas emitted from the refining tower in the monomer distillation process needs to be treated before being released into the atmosphere. Existing filtration systems typically use filter screens to remove dust from the exhaust gas. However, these screens generally require frequent replacement to maintain optimal filtration performance, which is undoubtedly inconvenient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide an organosilicon monomer distillation device, which significantly reduces the frequency of filter replacement and makes filter replacement more convenient.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] An organosilicon monomer distillation apparatus, comprising:

[0007] The filter tank has a tank body and a tank cover; the tank body has a drain outlet at the bottom and is open at the top, which is then covered by a matching tank cover, which has an air outlet.

[0008] The system includes an inlet pipe, a transfer pipe, a gas delivery pipe, an outlet pipe, and a rotary drive mechanism. The gas delivery pipe is sealed at both ends, with an outlet pipe connected to its bottom. Multiple outlet pipes are evenly distributed along the circumference of the gas delivery pipe. The inlet pipe passes through and is fixed to the side wall of the tank. One end forms a transfer pipe through which the gas delivery pipe passes. The two ends of the transfer pipe are sealed, and the two end walls are rotatably fitted onto the gas delivery pipe. The inner side of the transfer pipe has a vent hole opened on the gas delivery pipe. The gas delivery pipe is driven to rotate by a rotary drive mechanism installed inside the tank. The tank contains a filtrate that submerges the outlet pipe.

[0009] A filter screen and a filter screen washing mechanism are provided above the gas pipeline. The filter screen is detachably installed inside the tank and is washed by the filter screen washing mechanism set on the filter tank.

[0010] As an improvement, the rotary drive mechanism includes a motor and a belt and pulley structure; after the motor is installed and fixed inside the tank, the output shaft is connected to the gas pipeline through the belt and pulley structure.

[0011] As an improvement, the filter washing mechanism includes a plate brush, which is installed and fixed at the top of the air supply pipe and is movably connected to the bottom surface of the filter screen. The bristles of the plate brush are made of nylon.

[0012] As an improvement, the filter washing mechanism also includes an annular water pipe and nozzles; multiple nozzles are evenly arranged circumferentially on the lower side of the annular water pipe, the nozzles penetrate and are fixed on the tank cover, and a water inlet is provided on the upper side of the annular water pipe. The water inlet is connected to a high-pressure water pump through a water delivery hose to pump water or cleaning fluid into the annular water pipe.

[0013] As an improvement, the filter screen is secured to the tank body with multiple screws, allowing for easy installation and removal of the filter screen.

[0014] It is worth mentioning that the motors, water pumps, and high-pressure water pumps used in this technical solution are all existing devices that are common knowledge, and their use and control methods are all existing technologies.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. When this new type of equipment is in use, the exhaust gas emitted from the refining tower of the single distillation process is first passed into the filtrate, and then filtered by the filter screen, resulting in a good filtration effect. In addition, with the filter screen washing mechanism, the filter residue attached to the filter screen can be washed away in time, thereby extending the service life of the filter screen each time and greatly reducing the frequency of filter screen replacement.

[0017] 2. The replacement of the filter screen of this new type is also very convenient. Attached Figure Description

Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] An organosilicon monomer distillation apparatus, comprising:

[0025] The filter tank has a tank body 1 and a tank cover 2; the bottom of the tank body 1 is provided with a drain outlet 3, and the top is open and then covered by a matching tank cover 2, which has an air outlet 4.

[0026] The tank comprises an inlet pipe 5, a transfer pipe 6, a gas delivery pipe 7, an outlet pipe 8, a motor 11, and a belt and pulley structure. The gas delivery pipe 7 is sealed at both ends, with an outlet pipe 8 connected to its bottom. Multiple outlet pipes 8 are evenly arranged along the circumference of the gas delivery pipe 7. The inlet pipe passes through and is fixed to the side wall of the tank body 1, forming a transfer pipe 6 through which the gas delivery pipe 7 passes at one end. The transfer pipe 6 is sealed at both ends, with its end walls rotatably fitted onto the gas delivery pipe 7 (rotary sealing at the connection). The inner side of the transfer pipe 6 has a vent hole 9 opened on the gas delivery pipe 7. The motor 11 is installed and fixed inside the tank body 1, and its output shaft is connected to the gas delivery pipe 7 via a belt and pulley structure. The tank body 1 contains a filtrate that submerges the outlet pipe 8; the filtrate can be a charged ion solution, etc.

[0027] A filter screen 10 and a filter screen washing mechanism are provided. The filter screen 10 is installed inside the tank 1 above the gas supply pipe 7 and is fixed inside the tank 1 by multiple screws 16. The filter screen washing mechanism includes a brush 12, an annular water pipe 13, and nozzles 14; it is installed and fixed at the top of the gas supply pipe 7 and is movably connected to the bottom surface of the filter screen 10. Multiple nozzles 14 are evenly arranged circumferentially on the lower side of the annular water pipe 13, and the nozzles 14 penetrate and are fixed to the tank cover 2. A water inlet 15 is provided on the upper side of the annular water pipe 13.

[0028] In the specific implementation of this embodiment:

[0029] like Figure 1 and 2 As shown, the exhaust gas emitted from the refining tower of the single-unit distillation process enters the inlet pipe 5, then flows through the gas delivery pipe 7, and finally exits into the filtrate through the outlet pipe 8. After passing through the filtrate, the exhaust gas passes through the filter screen 10 and is finally discharged from the outlet 4. During the process, the motor 11 drives the gas delivery pipe 7 to rotate, which in turn drives the brush 12 to brush off the filter residue attached to the filter screen 10. The nozzle 14 sprays water onto the filter screen 10, which can improve the washing effect of the brush 12. At the same time, the rotation of the outlet pipe 8 can also stir the filtrate, thereby allowing the exhaust gas and the filtrate to mix more thoroughly, resulting in a better filtration effect.

[0030] It is worth mentioning that when you replace the filter screen 10 regularly, the filtrate should also be replaced.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
