Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a filterable reaction vessel for preparing chemical raw materials. Background Technology

[0002] A reaction vessel is a container for physical or chemical reactions. Through structural design and parameter configuration, it achieves functions such as heating, stirring, reaction, concentration, cooling, or mixing required for chemical synthesis or processes. It is widely used in fields such as chemistry, pharmaceuticals, petroleum, chemicals, rubber, pesticides, and fuels. In the preparation of chemical raw materials, stirring is usually necessary to promote reaction homogeneity, and solid-liquid separation is performed after the reaction to obtain the product.

[0003] Currently, existing reactors use filters or plates at the bottom for solid-liquid separation. However, this single-filtration structure has limited filtration efficiency and is easily clogged by material residue, thus affecting the liquid output efficiency.

[0004] Therefore, this application provides a filterable reaction vessel for the preparation of chemical raw materials to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a filterable reaction vessel for the preparation of chemical raw materials. In order to perform solid-liquid separation, existing reaction vessels will be equipped with filter screens or filter plates at the bottom for filtration. However, this single filtration structure not only has limited filtration effect during the liquid filtration process, but is also very easy to be blocked by material residue, thus affecting the liquid output efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A filterable reaction vessel for preparing chemical raw materials includes a vessel body, a vertical stirring column rotatably mounted in the center of the vessel body, several stirring blades symmetrically mounted on both sides of the stirring column, a hollow bottom of the stirring column, an opening at the lower end of the stirring column and a feed pipe connected thereto, the feed pipe being fixed to the center of the bottom surface of the vessel body, and horizontal discharge shafts connected to both sides of the bottom of the stirring column, an internal channel being provided inside the discharge shaft, and a sleeve-type filter cartridge being installed outside the discharge shaft;

[0008] The lower end of the feed pipe is open and a filter cylinder is detachably installed thereon, and a filter cone is provided on the top of the filter cylinder.

[0009] Optionally, the bottom of the vessel is fixed with multiple support legs, the top side of the vessel is equipped with a feed pipe, and the bottom of the vessel is also provided with a slag discharge pipe.

[0010] Optionally, a servo motor is provided at the top of the vessel body, and a reducer is fitted to the shaft of the servo motor. The reducer is fixed to the top of the vessel body, and the output end of the reducer is fixed to the top of the stirring column.

[0011] Optionally, a valve for controlling the opening and closing is installed at the top of the feed pipe.

[0012] Optionally, the filter cartridge is provided with a threaded portion around it and is threadedly installed with the lower port of the feed pipe.

[0013] Optionally, a cap is fixed around the bottom edge of the filter cartridge, and a sealing ring is provided on the cap to fit around the bottom of the filter cartridge.

[0014] Optionally, the swivel cap has a frustum-shaped structure, the curved surface of the swivel cap is a hollow filter screen structure, and it is connected to the hollow channel inside the filter cylinder. A discharge port is provided in the middle of the bottom surface of the filter cylinder.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the cooperation of the discharge shaft, the inner channel of the shaft, the sleeve-type filter cartridge, the feed pipe and the filter cartridge, two-stage filtration can be formed. The first stage of filtration is performed by the sleeve-type filter cartridge, which allows the liquid to enter the feed pipe through the inner channel of the shaft and the bottom of the stirring column. Then, the second stage of filtration is performed by the filter cone at the top of the filter cartridge, thereby ensuring the filtration effect.

[0017] In the above solution, thanks to the discharge shaft being installed at the bottom of the stirring column, the stirring column can drive the discharge shaft to rotate, thereby preventing the material residue from clogging the sleeve filter cartridge. Since the sleeve filter cartridge is a primary filter, it can effectively prevent the filter cartridge from clogging. Therefore, the filtration mechanism as a whole is not prone to clogging problems, which helps to ensure liquid output efficiency.

[0018] In summary, this device not only features multi-stage filtration to ensure filtration effectiveness but also prevents clogging, further guaranteeing liquid output efficiency and resulting in excellent overall performance. Attached Figure Description

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a filterable reaction vessel for preparing chemical raw materials, including a vessel body 1. The bottom of the vessel body 1 is fixed with a plurality of support legs 101. A feed pipe 102 is installed on the top side of the vessel body 1, and a slag discharge pipe 103 is also provided on the bottom edge of the vessel body 1. A valve for controlling the opening and closing of the slag discharge pipe 103 is provided on the slag discharge pipe 103.

[0033] A vertical stirring column 3 is rotatably mounted in the center of the vessel body 1, and several stirring blades 4 are symmetrically mounted on both sides of the stirring column 3. A servo motor 2 is installed at the top of the vessel body 1, and a reducer 201 is fitted to the shaft of the servo motor 2. The reducer 201 is fixed to the top of the vessel body 1, and its output end is fixed to the top of the stirring column 3. This allows the servo motor 2 to drive the stirring column 3 to move the stirring blades 4 to stir the materials inside the vessel body 1, ensuring a complete reaction.

[0034] Cooperate Figure 3 and Figure 4 As shown, the bottom of the stirring column 3 is hollow, and the lower end of the stirring column 3 is open and connected to the discharge pipe 6. Horizontal discharge shafts 5 are also connected to both sides of the bottom of the stirring column 3. An internal channel 501 is provided inside the discharge shaft 5, and a sleeve-type filter cartridge 502 is installed outside the discharge shaft 5, forming a primary filtration structure.

[0035] The feed pipe 6 is fixed to the center of the bottom surface of the vessel body 1. A valve for controlling the opening and closing is installed at the top of the feed pipe 6, and the lower end of the feed pipe 6 is open and detachably fitted with a filter cylinder 7. The top of the filter cylinder 7 is provided with a filter cone portion 701. Specifically, the filter cylinder 7 is provided with a threaded portion around it and is threadedly installed with the lower end of the feed pipe 6, forming a detachable installation.

[0036] Meanwhile, a cap 702 is fixed around the bottom edge of the filter cylinder 7, and a sealing ring 703 is provided on the cap 702 to fit around the bottom of the filter cylinder 7 to ensure a sealing effect.

[0037] In addition, in this embodiment, the swivel cap 702 has a frustum-shaped structure, and the curved surface of the swivel cap 702 is a hollow filter screen structure, which is connected to the hollow channel inside the filter cylinder 7. A discharge port is provided in the center of the bottom surface of the filter cylinder 7. Therefore, secondary filtration can be performed through the swivel cap 702.

[0038] The working principle provided by this utility model is that, in use, the filterable reaction vessel for preparing chemical raw materials allows the liquid to enter the inner channel 501 after primary filtration through the sleeve-type filter cartridge 502, then enter the feed pipe 6 through the bottom cavity of the stirring column 3, and after secondary filtration through the filter cone 701 at the top of the filter cartridge 7, it is discharged from the bottom opening of the filter cartridge 7 to form liquid effluent. The material residue can be discharged by opening the residue discharge pipe 103 after the liquid effluent is discharged.

[0039] In the above process, since the discharge shaft 5 is installed at the bottom of the stirring column 3, the stirring column 3 can drive the discharge shaft 5 to rotate, thereby preventing the material residue from clogging the sleeve filter cartridge 502. Due to the primary filtration of the sleeve filter cartridge 502, the filter cartridge 7 can be effectively prevented from clogging. Therefore, the filtration mechanism as a whole is not prone to clogging problems, which helps to ensure the liquid output efficiency.

[0040] In summary, this device not only features multi-stage filtration to ensure filtration effectiveness but also prevents clogging, further guaranteeing liquid output efficiency and resulting in excellent overall performance.
