Description

Technical Field

[0001] The utility model relates to the field of chloroacetaldehyde dimethyl acetal processing, and more specifically, it relates to a chloroacetaldehyde dimethyl acetal processing and extraction device. Background Art

[0002] Chloroacetaldehyde dimethyl acetal is an important chemical raw material solution, widely used in coatings, adhesives, polymers and other fields. In the processing of chloroacetaldehyde dimethyl acetal, extraction is a key step, which can effectively extract the effective components in the raw material solution, so the extraction device is needed.

[0003] During the extraction process of chloroacetaldehyde dimethyl acetal, a stirring paddle is needed to promote the mixing of the extractant and the raw material solution. However, the stirring paddle of the existing extraction device is generally fixed in height and located in the middle, with a limited stirring range and poor mixing effect. If the extractant is added in batches, the progress and effect of the experiment can be better controlled, and it is also beneficial to observe and monitor changes during the experiment. However, the existing extraction solvent requires manual addition of the extractant, which will undoubtedly greatly consume manpower if added in batches.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a chloroacetaldehyde dimethyl acetal processing and extraction device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a chloroacetaldehyde dimethyl acetal processing and extraction device.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it comprises an extraction tank with an opening at the top, one side of the extraction tank is fixedly connected to an electric repeated lifting assembly for driving two vertical plates to lift and lower via an N-shaped rod A, the ends of the vertical plates are fixedly connected to an electric stirring paddle, the other side of the extraction tank is detachably connected to an extractant tank via an N-shaped rod B, the bottom end of the extractant tank is fixedly connected to a pressing head, the side ends of the vertical plates are fixedly connected to a lifting plate, and the top end of the lifting plate and the bottom end of the pressing head are fixedly connected via screws.

[0007] Preferably, the electric repetitive lifting assembly includes a shell with a lower opening, a reciprocating screw driven by a motor is installed inside the shell, guide rails for sliding sliders are fixedly connected on both sides of the shell, a rod sleeve whose inner wall is threadedly connected to the reciprocating screw is fixedly connected between the sliders, and the two sides of the bottom end of the slider are fixed to the top of the vertical plate.

[0008] Preferably, a cover is threadedly connected to the top of the extractant tank, and the cover is opened to add a sufficient amount of extractant into the extractant tank in advance.

[0009] Preferably, an observation window made of tempered glass is provided on the surface of the extraction tank.

[0010] Preferably, support plates are fixedly connected to both sides of the bottom end of the extraction tank, and the ends of the support plates are fixedly connected to a cast iron counterweight base, and the bottom end of the extraction tank is interconnected with a discharge pipe equipped with a valve.

[0011] Preferably, a heating rod is provided inside the extraction tank, and the raw material solution is heated by the heating rod during extraction to accelerate the diffusion between molecules, thereby improving the extraction efficiency.

[0012] Preferably, a protrusion is fixedly connected to the surface of the extractant tank, a groove for inserting the protrusion is formed at the head of the N-shaped rod B, a through hole is formed at the head of the N-shaped rod B below the groove, and a screw threadedly connected to a nut on the outer wall is fixedly connected to the bottom end of the protrusion, so as to facilitate cleaning of the extractant tank.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model drives the vertical plate to move up and down through the electric repeated lifting component, and the vertical plate drives the electric stirring paddle to move up and down. At the same time, the vertical plate will repeatedly squeeze the pressing head when moving up and down, so that the extractant in the extractant tank is added to the extraction tank in batches through the pressing head.

[0015] 2. The extractant tank in the utility model can be disassembled from the extraction device through the detachable structure, so that the inside thereof can be easily cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The electric repetitive lifting component 3 includes a shell 301 with a lower opening, and a reciprocating screw rod 303 driven by a motor 302 is installed inside the shell 301. Guide rails 304 for sliding sliders 305 are fixedly connected on both sides of the shell 301. A rod sleeve 306 whose inner wall is threadedly connected to the reciprocating screw rod 303 is fixedly connected between the sliders 305. The bottom ends of the sliders 305 are fixed to the tops of the vertical plates 4. That is, the reciprocating screw rod 303 is driven to rotate by the motor 302, and the reciprocating screw rod 303 drives the rod sleeve 306 to move up and down. The rod sleeve 306 drives the slider 305 to move up and down. The slider 305 interacts linearly up and down along the guide rail 304, and the slider 305 drives the vertical plate 4 to move linearly up and down.

[0024] The surface of the extraction tank 1 is provided with an observation window 9 made of tempered glass. During the extraction process, the actual extraction status can be understood through the observation window 9. A heating rod is provided inside the extraction tank 1 (the heating rod needs to be installed in a suitable position, and the number can be multiple, but it must not conflict with the electric stirring paddle 18). During extraction, the raw material solution is heated by the heating rod to accelerate the diffusion between molecules, thereby improving the extraction efficiency. Support plates 10 are fixedly connected to both sides of the bottom end of the extraction tank 1, and the end of the support plate 10 is fixedly connected to a cast iron counterweight base 11. The bottom end of the extraction tank 1 is interconnected with a discharge pipe 12 equipped with a valve thereon. The cast iron counterweight base 11 is heavy and can stably support the device.

At the same time, the vertical plate 4 will repeatedly squeeze the pressing head 7 (the principle of the pressing head 7 is the same as the head of a large shampoo bottle) when moving up and down, so as to press The pressure head 7 adds the extractant in the extractant tank 6 into the extraction tank 1 in batches (select a suitable pressure head 7 according to the needs, and different pressure heads 7 spray different extractants at one time). In this way, the electric stirring paddle 18 can be raised and lowered to increase the stirring range, so that the mixing effect of the raw material solution and the extractant is better, and the extractant can also be automatically added in batches, which saves manpower.
