Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of decabromodiphenyl ethane processing equipment, and in particular to an evaporation and filtration mechanism for the production of decabromodiphenyl ethane. Background Technology
[0002] The evaporation and filtration press for decabromodiphenyl ethane production is a comprehensive equipment combination used in the production process of decabromodiphenyl ethane. It mainly consists of two parts: an evaporator and a filter press. The evaporator is used to heat and evaporate the reaction mixture containing decabromodiphenyl ethane, while the filter press plays a role in the post-evaporation process. By applying pressure, the liquid in the material is forced through the filter medium, while the solids (such as decabromodiphenyl ethane and impurities) remain on the filter cloth.
[0003] However, in existing technologies, when the evaporator and filter press are directly combined in an evaporation-filtration mechanism, although some volatile components are removed from the decabromodiphenyl ethane after evaporation, it may still contain some tiny particles or impurities that precipitate out due to evaporation and concentration. These substances tend to accumulate on the filter screen surface after entering the filter press, increasing the probability of filter screen clogging. In addition, the solubility of some components in the evaporated material may decrease due to factors such as temperature changes, leading to precipitation. These precipitates will adhere to the filter screen, reducing the effective filtration area and increasing the filtration resistance over time. Utility Model Content
[0004] The purpose of this invention is to address the problem in existing evaporation-filtration mechanisms that directly combine the evaporator and filter press. While the evaporation process removes some volatile components from the decabromodiphenyl ethane, it may still contain small particles or impurities precipitated during the evaporation and concentration process. These substances tend to accumulate on the filter screen surface after entering the filter press, increasing the probability of clogging. Furthermore, the solubility of certain components in the evaporated material may decrease due to temperature changes, leading to precipitation. These precipitates adhere to the filter screen, reducing its effective filtration area and increasing filtration resistance over time. Therefore, this invention proposes an evaporation-filtration mechanism for the production of decabromodiphenyl ethane.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: an evaporation and filtration mechanism for the production of decabromodiphenyl ethane, comprising an evaporation mechanism, wherein the evaporation mechanism includes an evaporator body, a discharge pipe fixedly connected to the upper part of the evaporator body, a pressure filtration mechanism fixedly connected to one end of the discharge pipe, the pressure filtration mechanism including a filter press, a piston plate and a drive shaft, a filter plate fixedly connected inside the filter press, the end of the discharge pipe fixedly connected to the filter press and located above the filter plate, a fixing frame fixedly connected to the side of the filter press, an electric push rod fixedly connected to the surface of the fixing frame, and the output end of the electric push rod penetrating through the top of the filter press and... A piston plate is fixedly connected, and a sealing ring is fixedly connected to the side of the piston plate. The sealing ring is in contact with the inner wall of the filter press. A motor is fixedly connected to the surface of the fixing frame. A connecting outer tube is fixedly connected to the output end of the motor. A collection box is fixedly connected to the surface of the filter plate. One end of the drive shaft is rotatably connected to the collection box, and the other end of the drive shaft is inserted into the connecting outer tube. A slot is provided inside the connecting outer tube. A limiting plate is fixedly connected to the surface of the drive shaft. The limiting plate is located inside the slot and inserted into the connecting outer tube. The drive shaft passes through the top of the filter press and the surface of the piston plate. A cleaning brush is fixedly connected to the side of the drive shaft. The bottom of the cleaning brush is in contact with the surface of the filter plate.
[0006] Preferably, a heat source inlet pipe is fixedly connected to one end of the evaporator body, and a heat source outlet pipe is fixedly connected to the other end of the evaporator body.
[0007] Preferably, a feed pipe is fixedly connected to the bottom of the evaporator body.
[0008] Preferably, a second connecting pipe is fixedly connected to the side of the filter press, and the connection end of the second connecting pipe to the filter press is located at the lower part of the filter plate.
[0009] Preferably, a one-way valve is fixedly connected to the surface of the second connecting pipe.
[0010] Preferably, a discharge pipe is installed at the bottom of the filter press.
[0011] Preferably, a No. 1 connecting pipe is fixedly connected to the top of the filter press, and a valve is fixedly connected to the surface of the No. 1 connecting pipe.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, when filtering materials, the motor drives the connecting outer tube to rotate. The limiting plate is inserted into the slot inside the connecting outer tube, thereby driving the drive shaft to rotate. The drive shaft then drives the cleaning brush to rotate, cleaning the surface of the filter plate to prevent the filter plate from being blocked and affecting the filtration efficiency. The particulate matter cleaned by the cleaning brush will fall into the collection box and be collected. As the electric push rod pushes the piston plate downward, the upper end of the drive shaft drives the limiting plate to slide downward. At this time, the drive shaft is in a state of rotating and moving downward, so that the pressure filtration mechanism can simultaneously pressurize and filter the raw material and clean the filter plate, improving the filtration efficiency.
[0014] 2. In this utility model, raw materials are fed into the evaporator body through the feed pipe, and heat is simultaneously supplied to the evaporator body through the heat source inlet pipe to carry out evaporation. The evaporated material enters the filter press chamber through the discharge pipe for filtration. The raw material is filtered on the upper part of the filter plate. During the filtration process, the piston plate is pushed downward by the electric push rod. At this time, the air on the upper part of the filter plate is compressed, forming a high-pressure area on the upper part of the filter plate, thereby pressurizing and filtering the raw material on the upper part of the filter plate and improving the filtration efficiency.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1
[0023] like Figures 1-4 As shown, this utility model provides an evaporation and filtration mechanism for the production of decabromodiphenyl ethane, including an evaporation mechanism 1. The evaporation mechanism 1 includes an evaporator body 11, with a discharge pipe 12 fixedly connected to the upper part of the evaporator body 11. A pressure filtration mechanism 2 is fixedly connected to one end of the discharge pipe 12. The pressure filtration mechanism 2 includes a filter press 21, a piston plate 26, and a drive shaft 28. A filter plate 212 is fixedly connected inside the filter press 21. The end of the discharge pipe 12 is fixedly connected to the filter press 21, and the end of the discharge pipe 12 is located above the filter plate 212. A fixing frame 22 is fixedly connected to the side of the filter press 21. An electric push rod 23 is fixedly connected to the surface of the fixing frame 22. The output end of the electric push rod 23 passes through the top of the filter press 21 and is fixedly connected to the piston plate 26. A sealing ring 27 is fixedly connected to the side of the piston plate 26. The sealing ring 27 fits against the inner wall of the filter press 21. The surface of the fixing frame 22 is fixedly connected to the piston plate 26. A motor 24 is fixedly connected to the filter press 21, and an external connecting pipe 25 is fixedly connected to the output end of the motor 24. A collection box 213 is fixedly connected to the surface of the filter plate 212. One end of the drive shaft 28 is rotatably connected to the collection box 213, and the other end of the drive shaft 28 is inserted into the external connecting pipe 25. A slot is provided inside the external connecting pipe 25. A limiting plate 214 is fixedly connected to the surface of the drive shaft 28. The limiting plate 214 is located inside the slot and inserted into the external connecting pipe 25. The drive shaft 28 passes through the top of the filter press 21 and the surface of the piston plate 26. A cleaning brush 29 is fixedly connected to the side of the drive shaft 28. The bottom of the cleaning brush 29 is in contact with the surface of the filter plate 212. A heat source inlet pipe 14 is fixedly connected to one end of the evaporator body 11, and a heat source outlet pipe 15 is fixedly connected to the other end of the evaporator body 11. A feed pipe 13 is fixedly connected to the bottom of the evaporator body 11, and a discharge pipe is installed at the bottom of the filter press 21.
[0024] The specific settings and functions of this embodiment are described in detail below. Raw materials are fed into the evaporator body 11 through the feed pipe 13, and heat is supplied to the evaporator body 11 through the heat source inlet pipe 14 to carry out evaporation. The material after evaporation is processed enters the filter press 21 through the discharge pipe 12 for filtration. The raw materials are filtered on the upper part of the filter plate 212. During the filtration process, the piston plate 26 is pushed downward by the electric push rod 23. At this time, the air on the upper part of the filter plate 212 is compressed, forming a high-pressure area on the upper part of the filter plate 212, thereby pressurizing and filtering the raw materials on the upper part of the filter plate 212 and improving the filtration efficiency.
[0025] When filtering materials, the motor 24 drives the connecting outer tube 25 to rotate. The limiting plate 214 is inserted into the slot inside the one-way valve 216, thereby driving the drive shaft 28 to rotate. The drive shaft 28 then drives the cleaning brush 29 to rotate. The cleaning brush 29 cleans the surface of the filter plate 212 to prevent the surface of the filter plate 212 from being blocked, which would affect the filtration efficiency. The particulate matter cleaned by the cleaning brush 29 will fall into the collection box 213 and be collected. As the electric push rod 23 pushes the piston plate 26 to move downward, the upper end of the drive shaft 28 drives the limiting plate 214 to slide downward. At this time, the drive shaft 28 is in a state of rotating and moving downward, so that the pressure filtration mechanism 2 can simultaneously pressurize and filter the raw material and clean the filter plate 212.
[0026] Example 2
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a first connecting pipe 210 is fixedly connected to the top of the filter press 21, and a valve 211 is fixedly connected to the surface of the first connecting pipe 210. A second connecting pipe 215 is fixedly connected to the side of the filter press 21. The connection end of the second connecting pipe 215 to the filter press 21 is located at the lower part of the filter plate 212, and a one-way valve 216 is fixedly connected to the surface of the second connecting pipe 215.
[0028] The overall effect of this embodiment is that when the piston plate 26 moves up and down, the valve 211 is opened to keep the pressure between the piston plate 26 and the filter press 21 balanced. During the downward movement of the piston plate 26, the one-way valve 216 does not discharge air. When the piston plate 26 moves upward, air enters the filter press 21 through the one-way valve 216 and the second connecting pipe 215 to replenish the air at the bottom of the filter plate 212, thus preventing the air at the bottom of the filter plate 212 from being discharged through the discharge pipe and causing insufficient air pressure.
[0029] The working principle of this utility model is as follows: Raw materials are fed into the evaporator body 11 through the feed pipe 13, and heat is supplied into the evaporator body 11 through the heat source inlet pipe 14 to carry out evaporation. The material after evaporation is processed enters the filter press 21 through the discharge pipe 12 for filtration. The raw materials are filtered on the upper part of the filter plate 212. During the filtration process, the piston plate 26 is pushed downward by the electric push rod 23. At this time, the air on the upper part of the filter plate 212 is compressed, so that a high pressure area is formed on the upper part of the filter plate 212, thereby pressurizing and filtering the raw materials on the upper part of the filter plate 212.
[0030] When filtering materials, the motor 24 drives the connecting outer tube 25 to rotate. The limiting plate 214 is inserted into the slot inside the connecting outer tube 25, thereby driving the drive shaft 28 to rotate. The drive shaft 28 then drives the cleaning brush 29 to rotate. The cleaning brush 29 cleans the surface of the filter plate 212 to prevent the surface of the filter plate 212 from being blocked, which would affect the filtration efficiency. The particulate matter cleaned by the cleaning brush 29 will fall into the collection box 213 and be collected. As the electric push rod 23 pushes the piston plate 26 to move downward, the upper end of the drive shaft 28 drives the limiting plate 214 to slide downward. At this time, the drive shaft 28 is in a state of rotating and moving downward, so that the pressure filtration mechanism 2 can simultaneously pressurize and filter the raw material and clean the filter plate 212.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
