Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a separator for diethyl maleate. Background Art

[0002] Diethyl maleate is a commonly used organic solvent, and its production requires a series of reactions and separation and purification processes; in the separation process of diethyl maleate, one step is to adopt a cooling crystallization method, by cooling the filtered solution to a certain temperature, so that the diethyl maleate in it crystallizes and precipitates; then, it is separated out, which is pure diethyl maleate.

[0003] Traditionally, the separation of the solution and crystals is carried out by using a filter screen filtration method. After the filtration is completed, the filter screen is disassembled, and the crystals on the surface of the filter screen are manually extracted. However, this method not only makes it impossible for the crystals to be concentrated in the same place during filtration, making it difficult to collect later, but also the operator will directly contact the purified crystals, posing a risk of harm to the operator.

[0017] 3. In this utility model, by starting the first motor, the scraper is driven to scrape along the inner wall surface of the mixing tank, preventing crystals from easily adhering to the inner wall of the mixing tank. Scraping the inner wall of the mixing tank can improve the mixing efficiency and quality, and reduce the waste of crystals. At the same time, due to the elastic effect of the spring, the spring closely adheres to the inner wall of the mixing tank, avoiding wear of the spring after long-term operation and preventing gaps from occurring in the contact with the inner wall, which would reduce the effect of scraping the crystals. At the same time, the spiral blade rotates to avoid the blockage phenomenon of the liquid flowing downward inside the mixing tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figures 1 - 4 , which is the first embodiment of the utility model, provides a separator for diethyl maleate, the separator for diethyl maleate includes a plurality of brackets 1, the top of the bracket 1 is fixedly connected with a base 2, a mixing tank 3 is arranged above the base 2, and the mixing tank 3 passes through the base 2, a scratching unit 4 is arranged in the inner cavity of the mixing tank 3, and a striking unit 5 and a flipping unit 6 are arranged at the bottom of the base 2; the striking unit 5 includes a support plate 1 51 fixedly connected to the bottom of the base 2, a motor 2 52 is arranged on one side of the support plate 1 51, and the output end of the motor 2 52 passes through the support plate 1 51 and is fixedly connected with a gear 1 53, a connecting frame 55 is arranged on one side of the support plate 1 51, an arc strip 54 is fixedly connected to the surface of the connecting frame 55, and the arc strip 54 slides along the serrations on the surface of the gear 1 53, and a ball 56 is fixedly connected to one end of the connecting frame 55.

[0030] The ball 56 is made of phenolic resin, which is a synthetic material with extremely high strength and rigidity, as well as excellent wear resistance. This material can quickly restore its shape after being impacted and maintain striking accuracy. In the initial state, the ball 56 is in a vertical downward state. After starting the motor 52, the ball 56 is driven to rotate. Due to the obstruction of the filter net bag 69, the ball 56 is struck at the same point.

[0031] The connecting frame 55 is Z-shaped, and one side of the top of the connecting frame 55 extends to the outside of the support plate 51; two groups of support plates 61 are fixedly connected to the bottom of the base 2, and a slide groove 62 is provided on the surface of the support plate 61, and two groups of sliders 63 are slidably connected inside the slide groove 62; one group of sliders 63 is L-shaped, and the top of the slider 63 is rotatably connected to a gear 2 64 through a fixed rod, one end of the gear 2 64 is fixedly connected to a support rod 65, a motor 3 66 is installed on the top of the slider 63, and the output end of the motor 3 66 is fixedly connected to a gear 3 67, and the gear 2 64 and the gear 3 67 are meshed, and a filter net bag 69 is fixedly connected to the surface of the support rod 65; a cylinder 68 is fixedly connected to one side of the support plate 51, and the output end of the cylinder 68 is fixedly connected to one side of the slider 63, and the support plate 2 61 and the support plate 1 51 are perpendicular.

[0032] During use, pour diethyl maleate into the inlet of the mixing tank 3. After cooling and crystallization, open the valve at the bottom outlet of the mixing tank 3 to pour the liquid and crystals inside the mixing tank 3 into the inside of the filter net bag 69. After filtering through the filter net bag 69, drain the liquid into one of the cavities at the bottom of the base 2. While pouring and filtering the liquid, start the second motor 52 to drive the first gear 53 to rotate, and at the same time drive the arc-shaped strip 54 to move along the sawteeth on the surface of the first gear 53. Since the connecting frame 55 is fixedly connected to the arc-shaped strip 54, the sphere 56 is driven to move accordingly, hitting the surface of the filter net bag 69, and hitting the side surface of the filter net bag 69 while filtering, so that the crystals on the side wall of the filter net bag 69 fall to the bottom of the filter net bag 69.

[0033] After all the crystals on the side wall fall to the bottom of the filter net bag 69 through the hitting of the sphere 56, start the cylinder 68 to drive the slider 63 to slide inside the chute 62 until the filter net bag 69 is placed above another group of cavities. Then start the third motor 66 to drive the third gear 67 to rotate, driving the second gear 64 to rotate drivenly, so as to drive the support rod 65 and the filter net bag 69 to rotate. The flipping of the filter net bag 69 causes the crystals inside the filter net bag 69 to fall into this cavity, completing the collection work.

[0034] Embodiment 2

[0035] Refer to Figures 1 - 6 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the scraping unit 4 includes a first motor 41 arranged on the top of the mixing tank 3. The output end of the first motor 41 is fixedly connected with a rotating rod, and a plurality of groups of support units 42 are circumferentially arranged on the surface of the rotating rod. Two groups of scraping plates 43 are arranged on one side of the support unit 42, and a spiral blade 44 is sleeved at the bottom of the rotating rod.

[0036] The support unit 42 includes a support column 421 fixedly connected to the rotating rod. A sleeve 422 is sleeved on the surface of the support column 421, and a spring 423 is arranged inside the sleeve 422; one end of the spring 423 is fixedly connected to the bottom of the inner cavity of the sleeve 422, the other end of the spring 423 is fixedly connected to the surface of the support column 421, and one side of the spring 423 is fixedly connected to the scraping plate 43.

[0037] During use, start the first motor 41 to drive the scraping plate 43 to scrape along the inner wall surface of the mixing tank 3. Due to the elastic action of the spring 423, the spring 423 is closely attached to the inner wall of the mixing tank 3, and at the same time drive the sleeve 422 to slide on the surface of the support column 421, scraping the crystals on the inner wall of the mixing tank 3 to the outlet of the mixing tank 3. When the first motor 41 rotates, it drives the spiral blade 44 to rotate at the same time, preventing blockage at the outlet and ensuring that the liquid and crystals can be discharged.
