Description

Technical Field

[0001] The utility model belongs to the technical field of methoxyphenamine distillation equipment, in particular to methoxyphenamine distillation equipment. Background Art

[0002] Among the methoxyphenamine distillation equipment, the distillation tower is the most commonly used equipment. The distillation tower is a tower-type gas-liquid contact device for distillation. It uses the different volatilities of the components in the mixture, that is, the different vapor pressures of the components at the same temperature. This property allows the light components in the liquid phase to be transferred to the gas phase, and the heavy components in the gas phase to be transferred to the liquid phase, thereby achieving the purpose of separation. The distillation tower is also a mass transfer and heat transfer device that is extremely widely used in the production of chemical products. At the same time, the distillation tower is also a commonly used equipment in the chemical industry.

[0003] A Chinese patent with the announcement number "CN220656441U" discloses a distillation tower, including a distillation tower body, wherein a first insulation layer and a second insulation layer are respectively provided on both sides of the outside of the distillation tower body, the first insulation layer and the second insulation layer are both arc-shaped, and a first mounting plate is fixedly connected to both sides of the outer arc surface of the first insulation layer; the utility model provides a distillation tower to solve the problem that if the external environment in which the existing distillation tower is located is relatively cold and harsh, the distillation operation inside the distillation tower may be affected.

[0004] However, this device still has some shortcomings. Since the first insulation layer and the second insulation layer are fixed by plugging structures such as plug rods and pull rods into each other, the disassembly method requires pulling out the plug rods and pull rods in sequence before they can be removed. For example, the pull rod needs to be pulled out first, but the first spring has a rebound ability. The user needs to keep the pull rod pulled out before completing the subsequent work of pulling out the plug rod. In addition, since this structure is provided on both sides of the first insulation layer and the second insulation layer, the efficiency of the subsequent disassembly and maintenance of the first insulation layer and the second insulation layer is reduced.

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a methoxyphenamine distillation device to solve the problems raised by the above background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] The lid is located on the inside of the first and second insulation shells, and the distillation tower is positioned at the bottom of the first and second insulation shells. A first clamping groove is provided on one side of the second insulation shell, and the first clamping groove runs through the second insulation shell and one side of the first insulation shell. A second clamping groove is provided on the inner wall of the first clamping groove, and a first circular groove is provided on the inner side of the first clamping groove. A retaining spring is installed on the inner side of the first circular groove, and a first clamping block is clamped on the inner side of the first clamping groove. The outer side of the first clamping block is fixedly connected to a second clamping block matching the second clamping groove, and the second clamping block is clamped on one side of the retaining spring. A sealing block is fixedly connected to one side of the second clamping block, and a protrusion is fixedly connected to one side of the sealing block. A protective plate is clamped on the other side of the first insulation shell and one side of the second insulation shell.

[0008] As an optimal technical solution, the bottom end of the distillation tower is fixedly connected with a support leg, which is fixedly connected to the four sides of the bottom end of the distillation tower near the corners. The bottom end of the support leg is coated with an anti-slip layer, and the anti-slip layer at the bottom end of the support leg covers the support leg.

[0009] As a preferred technical solution, an electromagnet is installed at the top of the distillation tower, the bottom end of the top cover is made of magnetic iron material, and the bottom end of the top cover is magnetically connected to the top end of the electromagnet.

[0010] As an optimal technical solution, the top of the cleaning ring is fixedly connected to a fixed plate, the outer side of the fixed plate is in contact with the inner wall of the distillation tower, a socket is opened on one side of the fixed plate, the socket extends to the interior of the distillation tower, and a plug is inserted into the inner side of the socket. The cleaning ring is inserted into the inner wall of the distillation tower through the fixed plate, the socket and the plug.

[0011] As an optimal technical solution, a rubber pad is fixedly connected to one side of the second insulation shell, one side of the rubber pad is in contact with the other side of the sealing block, and the first slot is located close to the inner side of the rubber pad.

[0012] As an optimal technical solution, a second circular groove is provided on the other side of the first insulation shell and one side of the second insulation shell, and a rotating shaft is rotatably connected to the inner side of the second circular groove. A spring clip is installed on one side of the rotating shaft, and a circular hole is provided on one side of the protective plate. A strip opening is provided on the inner wall of the circular hole. A limit block matching the circular groove is fixedly connected to one side of the spring clip, and a stop block matching the strip opening is fixedly connected to the outer side of the limit block, and the stop block protrudes from one side of the strip opening.

[0013] As an optimal technical solution, a third clamping block is fixedly connected to the other side of the first insulation shell and one side of the second insulation shell, and a third clamping slot matching the third clamping block is opened on the inner side of the protective plate, and the third clamping block is clamped to the inner side of the third clamping slot.

[0014] In summary, the present invention has the following beneficial effects:

[0015] When the first and second insulation shells are installed, the second clamping block is inserted into the circular groove through the first clamping block, and then the first clamping block is slightly rotated to adjust the angle of the second clamping block to an angle asymmetrical with the second clamping groove, and then the second clamping block is clamped and limited for a second time by the clamping spring, thereby effectively preventing the first and second insulation shells from being separated, and also effectively insulating the outer wall of the distillation tower. When it is necessary to disassemble and maintain it later, the user only needs to adjust the angle of the second clamping block to an angle symmetrical with the second clamping groove, and finally pull out the first clamping block, which not only achieves the convenience of installing the first and second insulation shells, but also achieves the purpose of facilitating disassembly and maintenance in the later stage.

[0016] Second, because the packing net is fixed on the inner wall of the distillation tower by cleaning and plugging, the adsorption of the electromagnet can effectively limit the position of the top cover, and it is also convenient for the user to remove the top cover later. When the packing net needs to be maintained and cleaned, the top cover is first removed, and then the plug is pulled out of the socket, and finally the cleaning ring can be pulled out along the inner wall of the distillation tower. At the same time, the cleaning ring can also scrape off the impurities on the inner wall of the distillation tower, which not only facilitates the later cleaning and maintenance of the packing net, but also achieves the purpose of facilitating the cleaning of impurities on the inner wall of the distillation tower.
