Description

Technical Field

[0001] This utility model relates to the field of phenol crystallization technology, specifically to a phenol crystallization tower structure that facilitates continuous feeding. Background Technology

[0002] Phenol is an organic compound with the chemical formula C6H5OH. It is a colorless, needle-like crystal with a characteristic odor and is toxic. It is an important raw material for the production of certain resins, bactericides, preservatives, and pharmaceuticals (such as aspirin). It can also be used for disinfecting surgical instruments and treating excrement, as well as for skin sterilization, relieving itching, and treating otitis media. It has a melting point of 43°C, is slightly soluble in water at room temperature, and readily soluble in organic solvents; at temperatures above 65°C, it is miscible with water in any proportion. Phenol is corrosive; contact with it can cause local protein denaturation. If its solution gets on the skin, it can be washed off with alcohol. A small portion of phenol exposed to air is oxidized by oxygen to quinone, turning pink. It turns purple upon contact with ferric ions; this method is commonly used to test for phenol.

[0003] Traditional phenol crystallization methods typically employ batch crystallizers. This method is time-consuming for large-scale phenol crystallization. To improve production efficiency, crystallization towers are generally used for crystallization. Through continuous crystallization, phenol is separated from the liquid mixture. Because phenol has a certain degree of toxicity, common phenol crystallization towers are usually closed structures. When adding phenol solution to the crystallization tower, it is generally transported through pipelines. Phenol is usually injected slowly during crystallization. Since the pipelines are generally long, the solution may crystallize prematurely due to temperature fluctuations during transport, leading to pipeline blockage.

[0004] Therefore, we propose a phenol crystallization tower structure that facilitates continuous feeding. Utility Model Content

[0005] The purpose of this invention is to provide a phenol crystallization tower structure that facilitates continuous feeding, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a phenol crystallization tower structure for convenient continuous feeding, comprising a crystallization tower shell, a storage tank placed above the crystallization tower shell, a sealing component installed on the top wall of the crystallization tower shell, the sealing component being used to control the storage tank to seal when feeding material into the crystallization tower shell, the sealing component preventing leakage during feeding, and a flow control component installed below the storage tank, the flow control component being used to control the solution inside the storage tank to slowly flow into the crystallization tower shell for use, the flow control component preventing the solution inside the storage tank from spilling to the outside when the storage tank is installed.

[0007] Preferably, the sealing assembly includes two fixing plates, both of which are fixedly connected to the bottom wall of the crystallization tower shell. Each fixing plate has a guide rod snapped into its interior. A sealing block is fixedly connected between the adjacent sides of the two guide rods. A set of elastic steel plates is fixedly connected between each sealing block and the fixing plate.

[0008] Preferably, the bottom surface of the storage tank is fixedly connected to a conveying port, the size of which is adapted to the size of the opening on the top surface of the crystallization tower shell.

[0009] Preferably, inclined grooves are provided above the sides of the two closed blocks that are close to each other.

[0010] Preferably, the flow control assembly includes a rod, and three guide plates are fixedly connected to the inner wall of the crystallization tower shell. The opening directions of each pair of adjacent guide plates are opposite. The upper surface of the uppermost guide plate is fixedly connected to the bottom end of the rod, and two elastic rings are fixedly installed between the inner walls of the conveying port.

[0011] Preferably, a mounting plate is fixedly connected to the bottom surface of the storage tank, and a sealing ring is fixedly connected to the bottom surface of the mounting plate.

[0012] Preferably, the position of the sealing ring corresponds to the position of the opening on the upper surface of the crystallization tower shell.

[0013] Preferably, the output port of the conveying port is provided with a matching sealing cap, which closes the conveying port when it is normally placed.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When crystallizing phenol solution, first fill the storage tank with the solution to be crystallized. Then, open the sealing cap of the delivery port and insert the delivery port into the upper surface of the crystallization tower shell. At this time, the bottom surface of the delivery port will first contact the inclined groove opened on the upper left side of the sealing block. The delivery port will push the two inclined grooves in a direction away from each other. At this time, due to the reaction force of the elastic steel plate, the sealing block will clamp the outer surface of the delivery port. When the delivery port is pulled out from the inside of the crystallization tower shell, the sealing block will automatically reset under the influence of the elastic force of the elastic steel plate, thereby achieving the function of sealing the opening of the top wall of the crystallization tower shell. By setting the guide rod and the locking plate, the sealing block can be more stable when moving left and right. After the delivery port is installed, under the influence of gravity, the sealing ring on the bottom surface of the mounting plate will further seal the interface on the upper surface of the crystallization tower shell.

[0016] By setting up a closed component, the entire process of injecting solution into the crystallization tower shell using a storage tank can be completely sealed, further preventing solution leakage from causing harm to workers. This also solves the problem that currently, solutions are generally transported via pipelines, which can easily lead to premature crystallization when the pipelines are too long.

[0017] 2. When the delivery port is inserted into the crystallization tower shell, the rod fixed to the uppermost guide plate will be inserted between the two elastic rings inside the delivery port. The rod will squeeze a certain gap between the two elastic rings. At this time, the solution inside the storage tank can flow from the gap into the surface of the uppermost guide plate under the influence of gravity, and then flow through several guide plates and finally into the lower part of the crystallization tower shell. At this time, the solution will crystallize in the lower part of the crystallization tower shell due to the temperature change inside the crystallization tower shell.

[0018] By setting up a flow control component, the solution can be continuously transported simply by inserting the delivery port into the interior of the crystallization tower shell. When the solution inside the storage tank is empty, the entire process can be completed by replacing the storage tank in a closed manner. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] Example 1: A phenol crystallization tower structure for convenient continuous feeding includes a crystallization tower shell 3, a storage tank 4 placed on top of the crystallization tower shell 3, a sealing component 1 installed on the top wall of the crystallization tower shell 3. The sealing component 1 is used to control the sealing of the storage tank 4 when feeding material into the crystallization tower shell 3, thus preventing leakage during feeding. A flow control component 2 is installed below the storage tank 4, and is used to control the slow flow of the solution inside the storage tank 4 into the crystallization tower shell 3, thus preventing the solution inside the storage tank 4 from spilling out during installation.

[0028] The sealing component 1 includes a fixing plate 6. There are two fixing plates 6, both of which are fixedly connected to the bottom wall of the crystallization tower shell 3. A guide rod 8 is snapped into the inside of each fixing plate 6. A sealing block 7 is fixedly connected between the adjacent sides of the two guide rods 8. A set of elastic steel plates 10 is fixedly connected between each sealing block 7 and the fixing plate 6.

[0029] The bottom surface of the storage tank 4 is fixedly connected to the conveying port 5, and the size of the conveying port 5 is adapted to the size of the opening on the top surface of the crystallization tower shell 3.

[0030] An inclined groove 9 is provided above the side of each of the two closed blocks 7 that are close to each other.

[0031] When crystallizing phenol solution, first fill the storage tank 4 with the solution to be crystallized. Then, open the sealing cap of the delivery port 5 and insert the delivery port 5 into the upper surface of the crystallization tower shell 3. At this time, the bottom surface of the delivery port 5 will first contact the inclined groove 9 opened on the upper left side of the sealing block 7. The delivery port 5 will push the two inclined grooves 9 in a direction away from each other. At this time, due to the reaction force of the elastic steel plate 10, the sealing block 7 will clamp the outer surface of the delivery port 5. When the delivery port 5 is pulled out from the inside of the crystallization tower shell 3, the sealing block 7 will automatically reset under the influence of the elastic force of the elastic steel plate 10, thereby achieving the function of sealing the opening of the top wall of the crystallization tower shell 3. By setting the guide rod 8 and the fixing plate 6 to engage, the sealing block 7 can be more stable when moving left and right. After the delivery port 5 is installed, the storage tank 4 will be affected by gravity, and the sealing ring 15 on the bottom surface of the mounting plate 14 will further seal the interface on the upper surface of the crystallization tower shell 3.

[0032] By setting up the sealing component 1, the entire process of injecting solution into the crystallization tower shell 3 using the storage tank 4 can be completely sealed, further preventing solution leakage from causing harm to personnel. This solves the problem that currently, solutions are generally transported via pipelines, which can easily lead to premature crystallization when the pipelines are too long.

[0033] Example 2: The flow control component 2 includes a rod 12. Three guide plates 13 are fixedly connected to the inner wall of the crystallization tower shell 3. The opening directions of each pair of adjacent guide plates 13 are opposite. The upper surface of the uppermost guide plate 13 is fixedly connected to the bottom end of the rod 12. Two elastic rings 11 are fixedly installed between the inner walls of the conveying port 5.

[0034] A mounting plate 14 is fixedly connected to the bottom surface of the storage tank 4, and a sealing ring 15 is fixedly connected to the bottom surface of the mounting plate 14.

[0035] The position of the sealing ring 15 corresponds to the position of the opening on the upper surface of the crystallization tower shell 3. A matching sealing cap is provided at the outlet of the conveying port 5, and the conveying port 5 is closed by the matching sealing cap when it is normally placed.

[0036] When the delivery port 5 is inserted into the crystallization tower shell 3, the insertion rod 12, which is fixedly connected to the upper surface of the top guide plate 13, will be inserted between the two elastic rings 11 inside the delivery port 5. At this time, the insertion rod 12 will squeeze a certain gap between the two elastic rings 11. At this time, the solution inside the storage tank 4 can flow from the gap into the surface of the top guide plate 13 under the influence of gravity, and then flow through several guide plates 13 and finally into the lower part of the crystallization tower shell 3. At this time, the solution will crystallize in the lower part of the crystallization tower shell 3 due to the temperature change inside the crystallization tower shell 3.

[0037] By setting the flow control component 2, the solution can be continuously transported by inserting the delivery port 5 into the interior of the crystallization tower shell 3. When the solution inside the storage tank 4 is empty, the storage tank 4 can be replaced in a completely closed manner.
