Description

Technical Field

[0001] This utility model relates to the field of hexanediol production technology, and in particular to an oil-alkali separation device for hexanediol production. Background Technology

[0002] In the production of hexanediol, fatty acid raw materials need to be neutralized with alkali to remove acidic impurities. During this stage, fatty acids react with excess sodium hydroxide to form sodium fatty acid soap (soap residue), which forms a highly emulsified oil-alkali mixture with unreacted alkali. Since the soap residue particles are dispersed at the micron level and the viscosity of the oil phase fluctuates significantly with temperature, if they are not separated in time, the residual alkali will cause poisoning and failure of the subsequent hydrogenation catalyst. At the same time, the soap residue will reduce the purity of the hexanediol product (<99.2%), and the direct discharge of soap-containing waste alkali will significantly increase the wastewater treatment cost. Therefore, an oil-alkali separation device is used for separation.

[0003] However, in some existing devices, after oil-alkali separation is achieved by settling, the oil phase and soap residue (including alkali solution) are distributed in layers. When the soap residue and alkali solution are discharged from the bottom of the device, it is difficult to control the critical point between them and the oil phase, resulting in slow discharge and easy discharge of too much oil phase, causing inaccurate separation. To address this, we propose an oil-alkali separation device for hexanediol production. Utility Model Content

[0004] The purpose of this invention is to provide an oil-alkali separation device for hexanediol production, which can solve the problem of inaccurate separation in some existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil-alkali separation device for hexanediol production, comprising:

[0006] The separator cylinder has a sealing plate hinged to its bottom.

[0007] A positioning mechanism is installed on the sealing plate and is used to assist the opening and closing of the sealing plate.

[0008] An isolation mechanism is installed inside the separation cylinder. The isolation mechanism includes an isolation plate, a sealing ring, a handle, and through slots. The isolation plate is installed inside the separation cylinder. A sealing ring is fixedly installed on the outer surface of the isolation plate. The sealing ring fits against the inner wall of the separation cylinder. A handle is fixedly installed on the top of the isolation plate. At least two sets of through slots are opened through the isolation plate.

[0009] Preferably, the isolation mechanism further includes a hanging plate, connecting rods, sealing plates, limiting rods, anti-detachment blocks, and handles. A hanging plate is provided directly above the isolation plate. At least two sets of connecting rods are fixedly installed at the bottom of the hanging plate. A sealing plate that fits against the top of the isolation plate is fixedly installed at one end of each set of connecting rods. A limiting rod is fixedly installed on the rear outer surface of the hanging plate. The limiting rod moves through the handle. An anti-detachment block is fixedly installed at one end of the limiting rod. A handle is fixedly installed at the top of the hanging plate.

[0010] Preferably, the positioning mechanism includes a positioning rod and a handle. The positioning rod is movably inserted through one side of the sealing plate, and a positioning groove is provided on one side of the separating cylinder. One end of the positioning rod is inserted into the positioning groove, and the other end of the positioning rod is fixedly installed with a handle.

[0011] Preferably, the positioning mechanism further includes a spring, with the spring sleeved on the positioning rod, and both ends of the spring being fixedly connected to the handle and the sealing plate, respectively.

[0012] Preferably, a servo motor is fixedly installed at the bottom of the sealing plate, and a stirring rod is rotatably installed at the top of the sealing plate, with the shaft of the servo motor being connected to the stirring rod via a transmission.

[0014] Preferably, two sets of mounting plates are fixedly installed on both outer surfaces of the separating cylinder.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The oil-alkali separation device for hexanediol production, through the isolation mechanism, after the oil and alkali are separated in the separation cylinder, can extend the open isolation plate into the critical point of oil-alkali separation and then close it to achieve oil-alkali isolation. Then, the soap residue and alkali can be discharged quickly and accurately. This solves the problem that in some existing devices, after oil-alkali separation is achieved by standing, the oil phase and soap residue (including alkali) are distributed in layers. When the soap residue and alkali are discharged from the bottom of the device, it is difficult to control the critical point between them and the oil phase, resulting in slow discharge and easy discharge of more oil phase, causing inaccurate separation. This improves the practicality of the device.

[0017] (2) The hexanediol production oil-alkali separation device, through the positioning mechanism, can realize the quick opening and closing of the sealing plate on the separation cylinder, which facilitates the quick discharge of soap residue and alkali solution. At the same time, the installation plate facilitates the installation of the device, ensuring the effectiveness of the device and promoting its use. Attached Figure Description

[0024] Please see Figure 1-3 This utility model provides a technical solution: an oil-alkali separation device for hexanediol production, including a separation cylinder 1, a positioning mechanism 4 and an isolation mechanism 3. A sealing plate 2 is hinged to the bottom of the separation cylinder 1. An installation hole is opened through the front side of the separation cylinder 1, and an observation window is installed in the installation hole. The positioning mechanism 4 is set on the sealing plate 2 and is used to assist the opening and closing of the sealing plate 2. A servo motor 5 is fixedly installed at the bottom of the sealing plate 2, and a stirring rod 6 is rotatably installed at the top of the sealing plate 2. The rotating shaft of the servo motor 5 is connected to the stirring rod 6 for transmission. A cover plate 7 is hinged to the top of the separation cylinder 1, and two sets of mounting plates 8 are fixedly installed on the outer surfaces of both sides of the separation cylinder 1.

[0025] The isolation mechanism 3 is located inside the separation cylinder 1. The isolation mechanism 3 includes an isolation plate 31, a sealing ring 32, a handle 33, and a through groove 34. The isolation plate 31 is located inside the separation cylinder 1. The sealing ring 32 is fixedly installed on the outer surface of the isolation plate 31. The sealing ring 32 is in contact with the inner wall of the separation cylinder 1. The handle 33 is fixedly installed on the top of the isolation plate 31. At least two sets of through grooves 34 are opened through the isolation plate 31.

[0026] The isolation mechanism 3 also includes a hanging plate 35, connecting rods 36, sealing plates 37, limiting rods 38, anti-detachment blocks 39, and handles 310. A hanging plate 35 is positioned directly above the isolation plate 31. At least two sets of connecting rods 36 are fixedly installed at the bottom of the hanging plate 35. A sealing plate 37 that fits against the top of the isolation plate 31 is fixedly installed at one end of each set of connecting rods 36. A limiting rod 38 is fixedly installed on the rear outer surface of the hanging plate 35. The limiting rod 38 extends movably through the handle 33. An anti-detachment block 39 is fixedly installed at one end of the limiting rod 38. The top of the hanging plate 35 is fixed... Equipped with a handle 310, the open isolation plate 31 can be extended into the critical point of oil-alkali separation after oil-alkali separation in the separation cylinder 1 via the isolation mechanism 3, and then closed to achieve oil-alkali separation. Then, soap residue and alkali can be discharged quickly and accurately. This solves the problem in some existing devices where the oil phase and soap residue (including alkali) are distributed in layers after oil-alkali separation by standing. When discharging soap residue and alkali from the bottom of the device, it is difficult to control the critical point between them and the oil phase, resulting in slow discharge and easy discharge of too much oil phase, causing inaccurate separation. This improves the practicality of the device.

[0027] The positioning mechanism 4 includes a positioning rod 41 and a handle 42. The positioning rod 41 is movably inserted through one side of the sealing plate 2. A positioning groove is provided on one side of the separating cylinder 1.

The positioning mechanism 4 also includes a spring 43. The spring 43 is sleeved on the positioning rod 41. Both ends of the spring 43 are fixedly connected to the handle 42 and the sealing plate 2, respectively. Through the positioning mechanism 4, the sealing plate 2 can be quickly opened and closed on the separating cylinder 1, which facilitates the rapid discharge of soap residue and alkali. At the same time, the installation plate 8 facilitates the installation of the device, ensuring the effectiveness of the device and promoting its promotion and use.

[0028] Working principle: First, remove the isolation mechanism 3, pour the mixture to be separated and the reactant into the separation cylinder 1, cover the cover plate 7, and then control the servo motor 5 to start and drive the stirring rod 6 to rotate for stirring. After thorough mixing, stop and wait for it to stand for separation. After the oil-alkali separation is completed, the oil phase is distributed in the upper layer, and the alkali and soap residue are distributed in the lower layer. Drive the rod 33 to slowly extend the isolation plate 31 into the separation cylinder 1. It passes through the groove 34 and crosses the oil phase to the critical point of oil-alkali separation. Then, slide the hanging plate 35 through the handle 310 to drive the sealing plates 37 to cover the grooves 34 so that the isolation plate 31 is closed, thus separating the oil and alkali. Then, pull the handle 42 to drive the positioning rod 41 to disengage from the positioning groove on the separation cylinder 1. Then, the sealing plate 2 can be opened, and the soap residue and alkali will be discharged directly. After collection, reset the sealing plates 37 and open the grooves 34. The oil phase will then be discharged through the grooves 34 for separate collection.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
