Description

Technical Field

[0001] This utility model belongs to the technical field of separation and purification equipment, and in particular to a separation and purification device for chemical production. Background Technology

[0002] Purification refers to the process of separating impurities from a mixture to increase its purity. As an important chemical method, purification plays a crucial role not only in chemical research but also in chemical production. Existing chemical production separation and purification equipment often employs rotation or overall heating to ensure uniform heating of the liquid during purification, thus guaranteeing high efficiency. However, when purifying substances with low boiling points, existing equipment requires condensation. Prolonged use can cause the condensing material or structure to heat up, hindering extended condensation purification operations and reducing purification efficiency.

[0003] For example (Authorization Announcement No. CN220176070U), a chemical production separation and purification device includes: a heating chamber; a condensing chamber located on one side of the heating chamber, both the heating chamber and the condensing chamber being mounted on the ground with mounting brackets, the heating chamber being positioned at a higher level and the condensing chamber at a lower level; a connecting pipe extending from the upper part of the condensing chamber to the heating chamber, and the connecting pipe being inclined; a heating pipe located at the bottom of the inner wall of the heating chamber, with the heating pipe located in the middle, and a gap on the inner side of the heating pipe; and a pressure plate that can slide up and down inside the heating chamber, the outer edge of the pressure plate contacting the inner wall of the heating chamber, and when the pressure plate slides to the uppermost position, the heating chamber connects to the connecting pipe. This device solves the problem of uneven heating of the purified liquid inside existing equipment. However, when purifying low-boiling-point liquids, especially when condensation is required, prolonged use of the pressure plate at the top can lead to temperature increases and reduced purification efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a chemical production separation and purification device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical production separation and purification device, comprising a box for chemical production separation and purification and a disc-shaped fixing plate fixedly welded to the bottom of the box for fixing, the top of the box being connected to a conical fixing cover that is easy to disassemble and install, the top of the fixing cover being connected to an inlet pipe and an outlet pipe, the inlet pipe passing through the fixing cover and connecting to a condenser cap disposed therein, the condenser cap being connected to the outlet pipe through a set pipe;

[0006] The inner wall of the enclosure is welded with a hollow circular support plate. The top of the support plate abuts against a semi-circular condenser cap. The outer wall of the condenser cap is connected to a fixed cover. The side wall of the fixed cover is slidably connected to the inner wall of the enclosure.

[0007] As a preferred embodiment, the outer periphery of the enclosure is provided with a connection port with a control valve. One end of the connection port extends through the side wall of the enclosure into its interior, and the connection port is located below the support plate.

[0008] As a preferred embodiment, the outer periphery of the housing is provided with four symmetrically arranged mounting holes for connection. Bolts for easy fixing are connected in the mounting holes, and the bolts pass through the mounting holes and connect to the threaded holes provided in the side wall of the fixed cover.

[0009] As a preferred embodiment, the bottom of the fixing plate is welded with four support legs for support and fixation, and the bottom of the fixing plate is screwed to a drive motor that provides power.

[0010] As a preferred embodiment, the output shaft of the drive motor extends through the fixed plate into the interior of the housing, and the output shaft of the drive motor is connected to one end of the rotating shaft.

[0011] As a preferred embodiment, the two ends of the rotating shaft are fitted with bushings for easy connection, and the outer periphery of the two bushings is symmetrically provided with C-shaped fixing frames for easy fixation. The inner wall of the fixing frame is rotatably connected with blades to improve the stirring efficiency.

[0012] As a preferred embodiment, a number of evenly spaced stirring paddles are welded to the outer periphery of the rotating shaft, and the side wall of the fixing frame is slidably connected to the inner side wall of the box.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This chemical production separation and purification device benefits from the design of a condenser cap. The edge of the condenser cap abuts against a support plate welded to the inner side wall of the housing. A fixing cover is installed above the condenser cap for connection to the housing. The side wall of the fixing cover has threaded holes, and symmetrical mounting holes are provided on the side wall of the housing. Bolts are installed in the mounting holes, passing through the threaded holes to connect the housing to the fixing cover, thus securing the condenser cap. Above the fixing cap are inlet and outlet pipes for connection. The condenser cap has pipes inside for easy circulation of coolant. The connection between the inlet and outlet pipes through the fixing cover allows the condenser cap to maintain a low temperature even after long-term use, facilitating the separation and purification of liquids used in chemical production and improving the efficiency of the device.

[0015] This chemical production separation and purification device benefits from the designed rotating shaft. One end of the rotating shaft is connected to the output shaft of the drive motor, and the fixed part of the drive motor is connected to the bottom screw of the fixed plate. Bushings are fitted on both ends of the rotating shaft, and C-shaped fixing frames for easy connection are symmetrically welded to the outer walls of the bushings. Blades are rotatably connected to the inner walls of the fixing frames, and several symmetrically distributed stirring blades are welded to the outer periphery of the rotating shaft. Driven by the drive motor, the fixing frames and stirring blades rotate, and in conjunction with the blades rotatably connected in the fixing frames, the liquid to be purified is stirred. This allows the liquid inside the tank to be fully heated by the heating plate embedded in the fixed plate, and the sliding action between the fixing frame and the inner wall of the tank prevents the inner wall of the tank from adhering to the material, making operation convenient.

[0016] This device solves the problem of maintaining a low temperature in the condensation structure when existing equipment cannot condense and purify low-boiling-point substances, thus improving the processing efficiency of the device. Attached Figure Description

[0027] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0028] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0029] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0030] Example

[0031] like Figures 1 to 7 As shown, this embodiment includes a box 1 for chemical separation and purification and a disc-shaped fixing plate 2 fixedly welded to the bottom of the box 1 for fixation. Four symmetrically arranged support legs 3 are welded to the bottom of the fixing plate 2 for easy connection. The support legs 3 separate the fixing plate 2 from the ground to facilitate ventilation at the bottom of the device. A heating plate for heating chemical separation and purification is set inside the fixing plate 2. The heating plate is located at the bottom of the box 1 and its size is the same as that of the box 1, so that the bottom of the box 1 is always uniformly heated.

[0032] The top of the housing 1 is connected to a conical fixed cover 6 that is easy to disassemble and install. The top of the fixed cover 6 is connected to an inlet pipe 7 and an outlet pipe 8. The inlet pipe 7 passes through the fixed cover 6 and connects to the condenser cap 19 located inside it. The condenser cap 19 is connected to the outlet pipe 8 through a set pipe. The inlet pipe 7 and outlet pipe 8 located on the top of the fixed cover 6 and the inlet pipe 7 and outlet pipe 8 located on the top of the condenser cap 19 are connected through a set connecting pipe. A pipe for coolant circulation is set inside the condenser cap 19, which facilitates the circulation of coolant in the pipe under the action of an external motor. This allows the condenser cap 19 to maintain a suitable temperature for condensing and purifying low-boiling-point substances even after long-term use, thereby improving the processing efficiency of the device.

[0033] A hollow, annular support plate 11 is welded to the inner wall of the housing 1. The top of the support plate 11 abuts against a semi-circular condenser cap 19. The outer wall of the condenser cap 19 is connected to a fixed cover 6. The side wall of the fixed cover 6 is slidably connected to the inner wall of the housing 1. Symmetrically arranged threaded holes 12 are provided on the bottom side wall of the fixed cover 6. The threaded holes 12 correspond one-to-one with the mounting holes 10 provided on the outer wall of the housing 1. The inner wall of the housing 1 is completed by bolts 5 provided inside the mounting holes 10 passing through the threaded holes 12. The condenser cap 19, which is connected to the support plate 11, is provided at the bottom of the fixed cover 6. The fixed cover 6 fixes the condenser cap 19, which facilitates the disassembly and cleaning of the entire device and makes it easy to use. A connection port 4 with a control valve is provided on the side wall of the box 1. The connection port 4 extends through the side wall of the box 1 into the inside of the box 1 and is located below the support plate 11. The purified liquid can be added into the box 1 through the connection port 4, which is convenient to use.

[0034] A drive motor 13 is screwed to the bottom of the fixed plate 2. The output shaft of the drive motor 13 passes through the fixed plate 2 and is connected to one end of the rotating shaft 16. Because the heating plate embedded inside the fixed plate 2 has a through hole in the middle that matches the output shaft of the drive motor 13, and heat insulation material, such as heat insulation cotton, is placed around the hole, the heating plate will not affect the winding inside the drive motor when it is working.

[0035] The outer circumference of the rotating shaft 16 is fitted with bushings 17 at both ends. The outer wall of the bushings 17 is welded with symmetrically arranged C-shaped fixing frames 14. The inner wall of the fixing frames 14 is rotatably connected with blades 15. Several evenly spaced stirring paddles 18 are welded to the outer wall of the rotating shaft 16. Driven by the drive motor 13, the rotating shaft 16 is rotated to stir the liquid used for purification inside the box 1. With the sliding connection between the fixing frames 14 and the side wall of the box 1, the liquid inside the box 1 can be heated evenly, improving the heating quality of the device.

[0036] The drive motor 13 is a conventional instrument, and its working principle, size and model are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0037] Working principle

[0038] When using this chemical production separation and purification device, the edge of the condenser cap 19 is connected to the support plate 11, and the fixed cover 6 is connected to the side wall and the inner side wall of the box 1. The connection is completed by bolts 5 passing through the threaded hole 12. At this time, the pipeline for conveying the purified liquid is connected to the connection port 4, and the control valve is opened to facilitate the delivery of the liquid to the inside of the box 1.

[0039] The heating plate embedded in the fixed plate 2 is started and the output shaft of the drive motor 13 is rotated in sync, which drives the fixed frame 14, the blade 15 and the stirring paddle 18 to rotate, mixing the liquid inside the box 1. Finally, the inlet pipe 7 and the outlet pipe 8 are connected to the external water pipe, and the coolant inside the condenser cap 19 is continuously circulated by the water pump, so that low boiling point chemical products can be continuously extracted.
