Description

Technical Field

[0001] The utility model relates to an esterification filtering and slag removal device. Background Art

[0002] Esterification is a type of organic chemical reaction, mainly the reaction of alcohol with carboxylic acid or inorganic oxygen-containing acid to produce ester and water. It is divided into three categories: the reaction of carboxylic acid with alcohol, the reaction of inorganic oxygen-containing acid with alcohol, and the reaction of inorganic strong acid with alcohol. The esterification reaction of carboxylic acid with alcohol is reversible, and the reaction is generally very slow, so concentrated sulfuric acid is often used as a catalyst. The reaction of polycarboxylic acid with alcohol can produce a variety of esters. The reaction of inorganic strong acid with alcohol is generally faster. A typical esterification reaction is the reaction of ethanol and acetic acid to produce ethyl acetate with an aromatic smell, which is the raw material for making dyes and medicines. Esterification reactions are widely used in organic synthesis and other fields.

[0003] In the prior art, the crude ester generated by the esterification reaction directly enters the distillation storage tank through a pipeline. The crude ester contains a lot of waste residue. This type of waste residue is directly pumped to the distillation storage tank along the pipeline, which causes the distillation storage tank to become dirty quickly, takes a long time to maintain, and is difficult to maintain.

[0004] Based on the above problems, we designed an esterification filtration and slag removal device installed at the front end of the distillation temporary storage tank to intercept the waste residue contained in the crude ester entering the distillation temporary storage tank. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an esterification filtering and slag removal device which is installed at the front end of a distillation temporary storage tank and can intercept waste slag contained in the crude ester entering the distillation temporary storage tank.

[0027] like Figure 1 and Figure 2An esterification, filtering and deslagging device is shown, comprising a tank body 1, an upper box body 2 is arranged at the upper end of the tank body 1, a stepped surface (not shown) is arranged inside the upper box body 2, a filter plate 21 is installed through the stepped surface, the filter plate 21 is fixed by bolts to ensure that it is not lifted up under the action of the material penetrating upward, filter holes 22 are evenly distributed on the plate surface of the filter plate 21, a box cover 2333 is detachably installed on the top of the upper box body 2, a feed pipe 23 is arranged on one side of the upper box body 2, and a discharge pipe 24 is arranged on the other side of the upper box body 2, and the material enters the tank body 1 through the feed pipe 23, then permeates upward from the filter plate 21, and is discharged from the discharge pipe 24.

[0028] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, one end of the tank body 1 is closed, and the other end is provided with an opening 121. A connecting plate 131 is provided at the inner axis of the tank body 1, near the opening 121. A threaded hole 141 is provided at the axis of the connecting plate 131. A bracket 151 is welded between the connecting plate 131 and the inner wall of the tank body 1. A tank cover 161 is detachably installed at the opening 121. A tapered hole 17 corresponding to the threaded hole 141 is provided at the axis of the tank cover 161. 1. A sealing ring 181 is arranged on the inner wall of the tapered hole 171, and a bolt 191 is fitted through the tapered hole 141. The bolt 191 is screwed into the threaded hole 141, and a plunger portion 122 for acting on the sealing ring 181 is arranged at the end of the bolt 191. A pressing plate 123 is arranged at the outer end surface of the plunger portion 122, and the pressing plate 123 acts on the surface of the tank cover 161. A plurality of handles 124 are arranged in an annular shape on the outer wall of the pressing plate 123.

[0029] The above technical solution is mainly designed for the maintenance of the tank body 1. After the waste residue is full, the tank cover 161 can be opened, and then personnel can enter the tank body 1 to process the waste residue.

[0030] In the traditional technology, such a tank body is usually provided with an opening at the top or the side, which makes it difficult to discharge the waste residue, but the present device does not have this technical problem.

[0031] See also Figure 6 As shown, a pipe 221 is provided at the bottom of the filter plate 21 , the lower end of the pipe 221 acts on the inner bottom of the tank body 1 , first filter holes 222 are evenly distributed on the pipe 221 , and the pipe 221 penetrates the filter plate 21 upward.

[0032] When it is necessary to clean the interior of the tank body 1, first open the box cover, then insert the extraction equipment into the pipe 221 to extract the residual crude ester in the tank body 1. After the extraction is completed, only waste residue remains in the tank body 1. At this time, open the tank cover for cleaning, which solves the problem of residual crude ester.

[0033] See also Figure 6 As shown, the lower end of the pipe 221 forms a spherical bottom 223 after a spherical transition, and the spherical bottom 223 is provided with a plurality of the first filter holes 222 in an annular shape near the bottom.

[0034] This technical solution is mainly designed for a cylindrical tank body 1 to facilitate the absorption of crude ester.

[0035] See also Figure 3 As shown, a first sealing ring 188 and a second sealing ring 199 are provided at the opening of the tank body 1, the first sealing ring 188 and the second sealing ring 199 are coaxially arranged, the first sealing ring 188 is located on the inner side of the second sealing ring 199, and the first sealing ring 188 and the second sealing ring 199 are both embedded in the tank body 1.

[0036] The first sealing ring 188 and the second sealing ring 199 are used to seal and thus leakage can be avoided.

[0037] The thickness of the first sealing ring 188 is greater than the thickness of the second sealing ring 199 .

[0038] This technical means first performs sealing through the first sealing ring 188. At this time, since the thickness of the second sealing ring 199 is relatively small, the second sealing ring 199 is not subjected to much pressure from the can cover and is more durable. When the sealing of the first sealing ring 188 is insufficient, sealing is performed through the second sealing ring 199.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
