[0002] Chloroacetaldehyde is an organic compound with the chemical formula C2HCl3O. It is a colorless oily liquid, miscible in water, soluble in ethanol, ether, and chloroform. It is mainly used as a raw material for the manufacture of pesticides such as DDT, trichlorfon, dichlorvos, and herbicides chloral-urea.

[0003] In the prior art, chloroacetaldehyde hydrate is a product of chloroacetaldehyde processing, and during the processing of chloroacetaldehyde hydrate, it is necessary to distill it to obtain chloroacetaldehyde hydrate. The existing distillation processing is generally carried out through a distillation tower, but the existing chloroacetaldehyde hydrate distillation is processed through a distillation tower, and the distillation efficiency is very low, resulting in a low production capacity of chloroacetaldehyde hydrate. Therefore, we propose a chloroacetaldehyde hydrate processing distillation device. Utility Model Content

[0004] The utility model aims to solve the shortcomings existing in the prior art. Chloraldehyde hydrate is a product of chloroacetaldehyde processing. During the processing of chloroacetaldehyde hydrate, it is necessary to distill it. After distillation, chloroacetaldehyde hydrate can be obtained. The existing distillation processing is generally carried out through a distillation tower. However, the existing chloroacetaldehyde hydrate distillation is processed through a distillation tower, and the distillation efficiency is very low, thereby resulting in a low production capacity of chloroacetaldehyde hydrate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A chloral hydrate processing distillation device comprises a cylindrical distillation tower body, a rectangular protection box is installed on the top of the distillation tower body, a driving motor is installed inside the protection box, a cylindrical first rotating shaft is installed at the output end of the driving motor and located inside the distillation tower body near the top, triangular scrapers are symmetrically installed on both sides of the first rotating shaft, a cylindrical connecting shaft is installed at the bottom of the first rotating shaft, a second rotating shaft also in a cylindrical shape is installed at the bottom of the connecting shaft, and a stirring roller is installed on the periphery of the second rotating shaft.

[0007] As a preferred solution of the utility model, a support plate with the same size as the scraper is installed on the wider side of the scraper, and six support rollers are evenly installed on the side of the support plate away from the scraper and close to the first rotating shaft, and the two ends of the support rollers are respectively fixed to the support plate and the first rotating shaft.

[0008] As a preferred solution of the utility model, a first rotating bearing is sleeved on the periphery of the connecting shaft near the center, and a bearing sleeve with an inner diameter consistent with the outer diameter of the first rotating bearing is installed on the periphery of the first rotating bearing.

[0009] As a preferred solution of the utility model, four connecting rollers are equidistantly installed on the periphery of the bearing sleeve, and a circular support ring is installed on the end of the connecting roller away from the bearing sleeve, and four fixed rollers fixedly connected to the inner wall of the distillation tower body are equidistantly installed on the periphery of the support ring.

[0010] As a preferred solution of the utility model, a second rotating bearing is installed at the periphery of the bottom of the second rotating shaft, and a fixing groove is opened at the periphery of the second rotating bearing and at the inner bottom of the distillation tower body.

[0011] The technical effect of adopting the above further solution is that the stability of the first rotating shaft, the connecting shaft and the second rotating shaft during rotation can be effectively improved by the second active bearing and the fixing groove.

[0012] As a preferred solution of the utility model, a mounting frame is installed on the periphery of the distillation tower body, and a reboiler connected to the distillation tower body through a pipeline is installed on the front of the mounting frame, and a condenser connected to the distillation tower body through a pipeline is installed on the top of the mounting frame near the right side surface, and a reflux tank connected to the condenser through a pipeline is installed below the condenser.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, through the setting of the driving motor, the driving motor can effectively drive the first rotating shaft to rotate, so that the first rotating shaft drives the scraper to scrape the liquid condensed on the top of the distillation tower body, so that it falls back into the bottom of the distillation tower body and is evaporated into steam, thereby improving the distillation efficiency. The heated liquid can be stirred by the second rotating shaft and the stirring roller, so that the steam evaporates faster and the distillation efficiency can be effectively improved. The connecting shaft and the fixed roller can effectively improve the stability of the first rotating shaft and the second rotating shaft during the rotation process, thereby ensuring the distillation efficiency.

[0023] Example 1

[0024] like Figure 1-3As shown, the utility model provides a technical solution: a chloroacetaldehyde hydrate processing distillation device, comprising a cylindrical distillation tower body 1, a rectangular protection box 2 is installed on the top of the distillation tower body 1, and a driving motor 3 is installed inside the protection box 2, which can effectively drive a first rotating shaft 4 to rotate, and then a cylindrical first rotating shaft 4 is installed at the output end of the driving motor 3 and located inside the distillation tower body 1 near the top, and then triangular scrapers 5 are symmetrically installed on both sides of the first rotating shaft 4, and a cylindrical connecting shaft 6 is installed at the bottom of the first rotating shaft 4, and then a second cylindrical rotating shaft 7 is installed at the bottom of the connecting shaft 6, and then a stirring roller 8 is installed on the periphery of the second rotating shaft 7.

[0025] Example 2

[0026] like Figure 1-3 As shown, a support plate 51 having the same size as the scraper 5 is installed on the wider side of the scraper 5, and six support rollers 52 are evenly installed on the side of the support plate 51 away from the scraper 5 and close to the first rotating shaft 4. The two ends of the support rollers 52 are respectively fixed to the support plate 51 and the first rotating shaft 4. The support plate 51 and the support rollers 52 can improve the stability between the scraper 5 and the first rotating shaft 4.

[0027] A first rotating bearing 61 is sleeved on the periphery of the connecting shaft 6 near the center, and a bearing sleeve 62 whose inner diameter is consistent with the outer diameter of the first rotating bearing 61 is installed on the periphery of the first rotating bearing 61. The first rotating bearing 61 can facilitate the rotation of the connecting shaft 6.

[0028] Four connecting rollers 63 are installed at equal intervals on the periphery of the bearing sleeve 62, and a circular support ring 64 is installed on the end of the connecting roller 63 away from the bearing sleeve 62, and four fixed rollers 65 fixed to the inner wall of the distillation tower body 1 are installed at equal intervals on the periphery of the support ring 64, which can improve the support for the connecting shaft 6, thereby ensuring the stability of the connecting shaft 6.

[0029] A second rotating bearing 71 is installed at the periphery of the bottom of the second rotating shaft 7 , and a fixing groove 72 is provided at the periphery of the second rotating bearing 71 and at the bottom of the distillation tower body 1 , which can improve the stability of the second rotating shaft 7 .

[0030] A mounting frame 11 is installed on the periphery of the distillation tower body 1, and a reboiler 12 connected to the distillation tower body 1 through a pipeline is installed on the front of the mounting frame 11, and a condenser 13 connected to the distillation tower body 1 through a pipeline is installed on the top of the mounting frame 11 near the right side surface, and a reflux tank 14 connected to the condenser 13 through a pipeline is installed below the condenser 13.

[0031] The working process of the utility model is as follows: when a chloroacetaldehyde hydrate processing distillation device is used for distillation, first, the liquid inside the distillation tower body 1 is heated by the reboiler 12, and while heating, the driving motor 3 is turned on. After the driving motor 3 is turned on, the first rotating shaft 4 is driven to rotate, and while the first rotating shaft 4 is rotated, the connecting shaft 6 is also driven to rotate. Similarly, the second rotating shaft 7 is rotated by the rotation of the connecting shaft 6, and while the second rotating shaft 7 is rotated, the stirring roller 8 is driven to stir the liquid. By stirring and turning the liquid, steam is formed faster, and the steam rises along the inside of the distillation tower body 1. The rising liquid enters the condenser 13 for condensation, and part of the steam condenses on the top of the distillation tower body 1 to form liquid. At this time, the first rotating shaft 4 drives the scraper 5 to scrape the inner wall, so that the liquid is accelerated to fall into the bottom of the distillation tower body 1, and is heated by the reboiler 12 to become steam again. The utility model can effectively improve the distillation efficiency of chloroacetaldehyde hydrate through design, thereby effectively improving the production capacity of chloroacetaldehyde hydrate.
