Description

Technical Field

[0001] The utility model relates to the technical field of chemical product production equipment, in particular to a filtration treatment device for chemical synthetic solutions. Background Art

[0002] N-cyanoethyl-N-benzylaniline is a light yellow white powder product synthesized by chemical means. It is mostly used to synthesize SE type disperse dyes. It not only has a high color fixation rate and sublimation fastness, but also is suitable for hot melt dyeing of polyester fibers. It can be used as an important organic intermediate and is widely used in the synthesis and preparation of pesticides and dye products. The conventional synthesis method of N-cyanoethyl-N-benzylaniline products is to synthesize water, N-cyanoethylaniline, sodium benzyl chloride carbonate solution and glacial acetic acid through multiple reactions. It is first made into a solution-like semi-finished product, and then through a series of processes such as drying to make a powdery finished product. In the production reaction process of N-cyanoethyl-N-benzylaniline products, some oil by-products will remain in the prepared solution. If they are not treated and the subsequent drying and other processes are directly carried out, oil-containing waste gas will be generated. The emission of these oil-containing waste gases will not only cause environmental pollution, but also the oil by-products will be directly wasted. It is an urgent need for enterprises to improve their production processes to filter the semi-finished solution of N-cyanoethyl-N-benzylaniline. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "left" and "right" in the present invention are all based on Figure 1 For reference direction:

[0020] like Figure 1 to Figure 3As shown, a chemical synthetic solution filtering treatment device comprises a bottom box 1, a filter box 2 and a rotary filtering mechanism 3, the filter box 2 is fixedly mounted on the top of the bottom box 1, a filtrate collecting area 11 is arranged in the bottom box 1, the filter box 2 plays a role in separating and filtering the semi-finished product liquid of N-cyanoethyl-N-benzylaniline, the separated solution is collected in the filtrate collecting area 11, a filtrate external discharge pipe 12 is connected to the bottom of the bottom box 1, when a large amount of solution is collected, the filtrate is discharged through the filtrate external discharge pipe 12, a filter chamber 21 is provided in the filter box 2, the separation and filtering operation is performed in the filter chamber 21, a raw liquid input port 22 is connected to the top of the filter box 2, a filtrate output port 23 is connected to the bottom of the filter box 2, the raw liquid input port 22 is used to introduce (pour) the semi-finished product liquid of N-cyanoethyl-N-benzylaniline, the filtrate output port 23 is used to output the filtered solution, the raw liquid input port 22 and the filtrate output port 23 are both connected to the filter chamber 2. 1. The connection point position of the raw liquid input port 22 is higher than the connection point position of the filtrate output port 23, and the raw liquid can form a downward flow movement in the sub-filter chamber 21 (water flows to a lower place, enters high and exits low, so as to form a downward flow effect of the raw liquid). The filtrate output port 23 is connected with a liquid guide pipe 24, which extends toward the filtrate collection area 11. The liquid guide pipe 24 can guide the treated solution to the filtrate collection area 11 for collection. The rotary filter mechanism 3 is installed at the position corresponding to the sub-filter chamber 21. The rotary filter mechanism 3 includes a main rotating shaft 31 and a filtrate plate 311. The main rotating shaft 31 is rotatably installed in the sub-filter chamber 21. A plurality of filtrate plates 311 are evenly connected to the outer wall of the main rotating shaft 31. The raw liquid in the downward flow can pass through the filtrate plate 311 to form a separation and filtration effect (a filter screen is installed on the filtrate plate 311. When the raw liquid passes through, grease cannot pass through, but the solution can pass through). When the main rotating shaft 31 rotates, it can drive the filtrate plate 311 to rotate together. Figure 1 As shown, in the present invention, the number of installed filtrate plates 311 is not less than eight, and the filtrate plates 311 need to rotate in a clockwise direction, so that the filtrate plates 311 just impact and collide with the downstream raw liquid, and can ensure that the raw liquid contacts with at least three filtrate plates 311 during the downstream process, forming a multi-pass oil separation and filtration effect. The above design makes the separation and filtration of the raw liquid more sufficient, and has the advantages of good filtration effect and high filtration efficiency. The utility model can well meet the urgent needs of enterprises for filtration treatment of N-cyanoethyl-N-benzylaniline semi-finished product solution.

[0021] like Figure 1 As shown, the connection point of the raw liquid input port 22 is set at the high point of the filter chamber 21, and the connection point of the filtrate output port 23 is set at the low point of the filter chamber 21. The above design can lengthen the downstream movement stroke of the raw liquid, so that it can contact with more filtrate plates 311 when passing through the filter chamber 21, forming a better filtration effect.

[0022] like Figure 2As shown, the rotary filtering mechanism 3 also includes a rotary power component 33 and a lifting drive component 34. One end of the main rotating shaft 31 extends to the outside of the filter box 2 and is fixedly connected to a transmission gear 32. The rotary power component 33 and the lifting drive component 34 are both installed on the outside of the filter box 2, and the rotary power component 33 is installed above the lifting drive component 34. The rotary power component 33 can be driven by the lifting drive component 34 to perform vertical lifting movement. After the rotary power component 33 rises, it can be connected to the transmission gear 32, and then it can drive the main rotating shaft 31 and the filtrate plate 311 to rotate, forming a filtering operation effect. After the lifting drive component 34 drives the rotary power component 33 to descend, the rotary power component 33 is separated from the transmission gear 32, and the main rotating shaft 31 loses power. At this time, the filtrate plate 311 can be disassembled, replaced, and grease removed.

[0023] like Figure 2 As shown, the rotary power assembly 33 includes a motor frame 331 and a motor 332. The motor 332 is fixedly mounted on the motor frame 331. The output end of the motor 332 is fixedly connected with a driving pinion 333. The driving pinion 333 can mesh with the transmission gear 32. After the driving pinion 333 and the transmission gear 32 are meshed, the output power of the motor 332 can be transmitted to the main shaft 31 to drive it to rotate. Since it is a small-driven large transmission structure, a slow rotation effect of the filtrate plate 311 can be formed (during the filtration operation, the filtrate plate 311 should not rotate too fast).

[0024] like Figure 2 As shown, the lifting drive assembly 34 includes a fixed frame 341 and a guide rod 342. The fixed frame 341 is fixedly installed on the outer wall of the filter box 2. The two guide rods 342 are vertically installed on the fixed frame 341. The motor frame 331 is installed on the two guide rods 342. The guide rods 342 play a role in guiding the movement of the motor frame 331, so that the rotary power assembly 33 can only be lifted vertically. A lifting push rod 343 is also installed on the fixed frame 341. The lifting push rod 343 is a threaded rod. The top end of the lifting push rod 343 is rotatably connected to the motor frame 331. The bottom end of the lifting push rod 343 is connected to a second power-assisted turntable 344. The lifting push rod 343 is installed in a threaded connection. Pushing the second power-assisted turntable 344 can drive the lifting push rod 343 to rotate, so that the rotary power assembly 33 thereon can achieve lifting movement.

[0025] like Figure 2 As shown, a first power-assisted turntable 321 is fixedly connected to the transmission gear 32. After the rotary power assembly 33 is separated from the transmission gear 32, the rotation of the main shaft 31 and the filtrate plate 311 can be manually operated by twisting the first power-assisted turntable 321. This operation is performed when the filtrate plate 311 is disassembled or assembled.

[0026] like Figure 1 and Figure 3As shown, a plurality of filter plate seats 312 are fixedly installed on the outer wall of the main rotating shaft 31, and the filtrate plates 311 can be inserted into the filter plate seats 312 one by one. The filter plate seats 312 are provided with a plug-in plate groove 3121 and a spring hole 3122. The plug-in plate groove 3121 and the spring hole 3122 are connected. A spring 313 is installed in the spring hole 3122, and one end of the spring 313 extends into the plug-in plate groove 3121. The filtrate plate 311 is provided with a round head end 3111 and a flat head end 3112. The flat head end 31 12 sizes match the plug-in plate slot 3121, the filtrate plate 311 is inserted into the plug-in plate slot 3121 with the flat end 3112 and pressed onto the spring 313. After the filtrate plate 311 is installed, due to the space limitation of the sub-filter chamber 21, under the thrust of the spring 313, the round end 3111 of the filtrate plate 311 can contact the inner wall of the sub-filter chamber 21. The purpose of designing the round head is to ensure sealing while not affecting the rotation flexibility of the filtrate plate 311 (the round head has only linear contact, and the friction is small when rotating).

[0027] like Figure 1 As shown, a sealing plug 25 is installed on the top of the filter box 2. After the sealing plug 25 is installed, it can be spliced ​​to form a complete inner wall of the filter chamber 21. The sealing plug 25 must be installed before the filter operation so as not to affect the rotation of the filtrate plate 311. After the sealing plug 25 is removed, a top opening can be formed. Since the filtrate plate 311 is elastically inserted on the filter plate seat 312, it relies on the thrust of the spring 313 to maintain contact with the inner wall of the filter chamber 21. Therefore, when the sealing plug 25 is removed, the filter chamber 21 will form an opening. When the filtrate plate 311 rotates to the opening, the filtrate plate 311 will bounce upward due to the thrust of the spring 313. The worker can manually pick up the filtrate plate 311 that has jumped out. The above-mentioned removal operation of the filtrate plate 311 is very convenient.

[0028] like Figure 1 As shown, a secondary filter disc 26 is fixedly installed in the bottom box 1. The secondary filter disc 26 can be installed in a drawer style. The secondary filter disc 26 is installed correspondingly at the position below the liquid inlet pipe 24. After the filtrate plate 311 filters the raw liquid, grease will remain on the filter screen to form an oil layer. If it is not cleaned for a long time, the oil layer will have a problem of partial shedding. The shed grease may fall into the filtrate output port 23, which will contaminate the already filtered solution again. In order to solve the above problem, a secondary filter disc 26 is installed below the liquid inlet pipe 24. The solution output by the liquid inlet pipe 24 must be filtered again by the secondary filter disc 26. The secondary filter disc 26 can receive the abnormally fallen grease.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
