Abstract

This utility model discloses an N-ethylcarbazole separation and purification device, belonging to the field of separation and purification technology. It includes a reaction vessel with a conveying pipe fixedly connected to its bottom side, and a valve installed on the conveying pipe. In this N-ethylcarbazole separation and purification device, after N-ethylcarbazole precipitates, the operator rotates the valve to allow N-ethylcarbazole and unreacted raw materials to flow down from the conveying pipe and onto filter plates in a filter box. N-ethylcarbazole remains above the filter plates, while unreacted raw materials flow through the filter plates and accumulate at the bottom of the filter box. The operator then starts a first motor to drive an auger, evenly pushing the N-ethylcarbazole on the filter plates towards the discharge port for discharge. This facilitates the separation of precipitated N-ethylcarbazole from unreacted raw materials, preventing excessive unreacted raw materials from remaining on the surface after N-ethylcarbazole precipitation, which would render the N-ethylcarbazole unusable directly. This improves the functionality of the separation and purification device.

[0001] This utility model belongs to the field of separation and purification technology, specifically an N-ethylcarbazole separation and purification device. Background Technology

[0002] N-Ethylcarbazole separation and purification equipment refers to a specialized chemical equipment system used for the efficient separation and purification of N-ethylcarbazole from crude products or mixtures. Its core function is to remove impurities through physical or chemical means to improve the purity and yield of the target product. Current N-ethylcarbazole separation and purification equipment does not have the function of separating the precipitated N-ethylcarbazole from unreacted raw materials. After N-ethylcarbazole precipitates, it cannot be further filtered, resulting in N-ethylcarbazole mixing with unreacted raw materials, making it unusable directly. Therefore, a N-ethylcarbazole separation and purification equipment with filtration function is needed. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an N-ethylcarbazole separation and purification device, which solves the problem that the N-ethylcarbazole separation and purification device does not have the function of separating the precipitated N-ethylcarbazole and unreacted raw materials. After N-ethylcarbazole is precipitated, it is impossible to further filter the N-ethylcarbazole, resulting in N-ethylcarbazole mixing with unreacted raw materials and making it unusable directly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an N-ethylcarbazole separation and purification device, comprising a reaction vessel, a conveying pipe fixedly connected to the bottom of the reaction vessel, a valve installed on the conveying pipe, a filter box fixedly connected to the bottom of the conveying pipe, two support columns installed on the filter box, the top ends of the support columns fixedly connected to the bottom of the reaction vessel, an auger connected to the inner wall of the filter box via bearings, one end of the auger penetrating and snapped into the filter box, a first motor installed at the end of the auger extending out of the filter box, the first motor fixedly connected to the filter box, a filter plate provided below the auger, the filter plate fixedly connected to the filter box, guide plates installed on both sides of the filter plate, the guide plates fixedly connected to the filter box, and an outlet opening at one end of the auger corresponding to the filter box.

[0005] As a further embodiment of this utility model: a feed pipe is fixedly connected to the reactor, and a hopper is installed at the top of the feed pipe.

[0006] As a further embodiment of this utility model: a second motor is fixedly connected to the reactor, a rotating rod is installed on the bottom side of the second motor, the rotating rod is engaged with the reactor, the bottom end of the rotating rod is connected to the inner wall of the reactor through a bearing, a bracket is fixedly connected to both sides of the rotating rod, a scraper is installed on the side of the bracket, and the scraper is in contact with the inner wall of the reactor.

[0007] As a further embodiment of this utility model: a heating shell is fixedly connected to the outside of the reaction vessel, and a plurality of heating screws are installed on the inner wall of the heating shell.

[0008] As a further embodiment of this utility model: a protective shell is fitted onto the outside of the second motor, and the protective shell is fixedly connected to the reaction vessel.

[0009] As a further embodiment of this utility model: four anti-slip pads are installed on the bottom side of the filter box, and the four anti-slip pads are respectively arranged at the four corners of the bottom side of the filter box.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This N-ethylcarbazole separation and purification equipment, through the setting of a conveying pipe, filter box, valve, auger, first motor, filter plate and discharge port, after N-ethylcarbazole precipitates, the operator turns the valve to let N-ethylcarbazole and unreacted raw materials flow down from the conveying pipe and onto the filter plate in the filter box. N-ethylcarbazole remains on the top of the filter plate, while unreacted raw materials flow down through the filter plate and accumulate at the bottom of the filter box. The operator then starts the first motor to drive the auger to rotate, pushing the N-ethylcarbazole on the filter plate evenly to the discharge port and discharging it. This facilitates the separation of precipitated N-ethylcarbazole from unreacted raw materials and prevents excessive unreacted raw materials from remaining on the surface of N-ethylcarbazole after precipitation, which would render the N-ethylcarbazole unusable directly. This improves the functionality of the separation and purification equipment.

[0012] 2. This N-ethylcarbazole separation and purification equipment, by setting up a reaction vessel, a second motor, a rotating rod, a support, and a scraper, collects N-ethylcarbazole adhering to the inner wall of the reaction vessel. When collecting N-ethylcarbazole, the operator starts the second motor to drive the rotating rod to rotate, and the rotating rod drives the support and scraper to rotate, thereby scraping off the N-ethylcarbazole adhering to the inner wall of the reaction vessel. This prevents a large amount of N-ethylcarbazole from adhering to the inner wall of the reaction vessel, which would lead to the waste of N-ethylcarbazole resources, and improves the resource utilization rate of the separation and purification equipment.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: an N-ethylcarbazole separation and purification device, including a reaction vessel 1, a feed pipe 11 fixedly connected to the reaction vessel 1, and a hopper 12 installed at the top of the feed pipe 11. Because of the hopper 12, when separating and purifying N-ethylcarbazole, the operator pours the raw material into the hopper 12. The raw material flows down along the inclined surface of the hopper 12 and flows into the reaction vessel 1 through the feed pipe 11, preventing the raw material from splashing to the outside during the feeding process, thus avoiding the waste of N-ethylcarbazole resources and improving the functionality of the separation and purification device.

[0019] A second motor 13 is fixedly connected to the reactor 1. A rotating rod 14 is mounted on the bottom side of the second motor 13 and is engaged with the reactor 1. The bottom end of the rotating rod 14 is connected to the inner wall of the reactor 1 via a bearing. Supports 15 are fixedly connected to both sides of the rotating rod 14. Scrapers 16 are mounted on the sides of the supports 15 and are in contact with the inner wall of the reactor 1. A conveying pipe 2 is fixedly connected to the bottom side of the reactor 1. A valve 5 is mounted on the conveying pipe 2. A filter box 3 is fixedly connected to the bottom side of the conveying pipe 2. Two support columns 4 are mounted on the filter box 3. The top ends of the support columns 4 are fixedly connected to the bottom side of the reactor 1. An auger 6 is connected to the inner wall of the filter box 3 via a bearing. One end of the auger 6 is connected to the filter box. 3. A through-hole snap-fit ​​connection is made. One end of the auger 6 extending out of the filter box 3 is equipped with a first motor 7. The first motor 7 is fixedly connected to the filter box 3. A heating shell 17 is fixedly connected to the outside of the reaction vessel 1. Several heating screws 18 are installed on the inner wall of the heating shell 17. Because of the heating screws 18, when N-ethylcarbazole is precipitated, the operator starts the heating screws 18 in the heating box to heat the raw material in the reaction vessel 1 until N-ethylcarbazole can be precipitated. This facilitates uniform heating of the raw material in the reaction vessel 1 and prevents N-ethylcarbazole from not being completely precipitated due to uneven heating of the raw material. This improves the stability of the separation and purification equipment when precipitating N-ethylcarbazole.

[0020] The second motor 13 is fitted with a protective shell 19, which is fixedly connected to the reaction vessel 1. The protective shell 19 protects the second motor 13 from external influences, preventing it from rusting or being damaged, thus improving the functionality and protection of the separation and purification equipment. A filter plate 8 is installed below the auger 6, which is fixedly connected to the filter box 3. Guide plates 9 are installed on both sides of the filter plate 8, which are also fixedly connected to the filter box 3. An outlet 10 is opened at one end of the auger 6 corresponding to the filter box 3. Four anti-slip pads 20 are installed on the bottom side of the filter box 3, which are respectively arranged at the four corners of the bottom side of the filter box 3. The anti-slip pads 20 prevent the bottom side of the filter box 3 from directly contacting the ground, preventing the separation and purification equipment from tipping over due to water or oil on the ground, thus improving the overall stability of the separation and purification equipment.

[0021] The working principle of this invention is as follows: When separating and purifying N-ethylcarbazole, the operator pours the raw material into hopper 12. The raw material flows down the inclined surface of hopper 12 and into reactor 1 through feed pipe 11. Then, the heating screw 18 in the heating box is started to heat the raw material in reactor 1 until N-ethylcarbazole can precipitate. After N-ethylcarbazole precipitates, the operator turns valve 5 to allow N-ethylcarbazole and unreacted raw material to flow down from conveying pipe 2 and into filter box 3. On plate 8, N-ethylcarbazole remains above filter plate 8, while unreacted raw materials flow down through filter plate 8 and accumulate at the bottom of filter box 3. The operator then starts the first motor 7 to drive the auger 6 to rotate, pushing the N-ethylcarbazole on filter plate 8 evenly towards the outlet 10 and discharging it. When collecting the N-ethylcarbazole adhering to the inner wall of reactor 1, the operator starts the second motor 13 to drive the rotating rod 14 to rotate. The rotating rod 14 drives the support 15 and scraper 16 to rotate, thereby scraping off the N-ethylcarbazole adhering to the inner wall of reactor 1.
