Description

Technical Field

[0001] This utility model relates to the field of 1,4-butenediol preparation technology, and more particularly to a 1,4-butenediol evaporation and concentration circulating mixed flow device. Background Technology

[0002] 1,4-Butenediol is a chemical substance with the molecular formula C4H8O2. It is a colorless or light amber oily liquid. For storage and transportation, it should be stored in a well-ventilated hazardous materials warehouse below 35°C, insulated from heat and light. The storage period is generally no more than three months. The storage tank is used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids.

[0003] In the prior art, during the use of 1,4-butenediol evaporation and concentration circulating mixed flow devices, some 1,4-butenediol evaporation and concentration circulating mixed flow devices do not have internal turning equipment when evaporating materials, resulting in low evaporation efficiency. Secondly, when cooling and concentrating the evaporated materials, the fixed position of the cooling copper pipes prevents them from making sufficient and rapid contact with the evaporated materials. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a 1,4-butenediol evaporation and concentration circulating mixed flow device, comprising: a base plate, four pillars equidistantly installed at one end of the top of the base plate, a heating evaporation tank installed on the top of the four pillars, a stirring device provided in the inner cavity of the heating evaporation tank, a feed inlet fixedly penetrating the top of the surface of the heating evaporation tank, a support plate installed at the other end of the top of the base plate, a cooling tank installed on the top of the support plate, a cooling device provided in the inner cavity of the cooling tank, and a discharge pipe fixedly penetrating the bottom of one end of the cooling tank.

[0006] In a preferred embodiment, a pressure relief port is provided on one side of the top of the heating evaporation tank, and a connecting pipe is fixedly inserted through the other side of the top of the heating evaporation tank. One end of the connecting pipe is fixedly inserted through the top of the other end of the cooling tank, and a cooling connecting telescopic hose is embedded through one end of the cooling tank.

[0007] In a preferred embodiment, the stirring device includes a motor, the output end of which is fixedly connected to a drive shaft, and three fixing rings are equidistantly mounted on the surface of the drive shaft, with multiple stirring plates equidistantly mounted around the surfaces of the three fixing rings.

[0008] In a preferred embodiment, the top of the motor is mounted at the center of the bottom of the heating evaporation tank, the bottom end of the drive shaft is mounted through a sealed bearing at the center of the bottom of the heating evaporation tank, and the top end of the drive shaft is mounted through a bearing at the center of the top of the heating evaporation tank.

[0009] In a preferred embodiment, the cooling device includes a forward and reverse motor, the output end of which is fixedly connected to a transmission rod. Hollow copper plates are installed at both ends of the transmission rod, and cooling copper pipes are equidistantly mounted around the opposite sides of the two hollow copper plates.

[0010] In a preferred embodiment, one end of the forward and reverse motor is installed at the center of one end of the cooling tank, one end of the transmission rod surface passes through one end of the cooling tank via a sealed bearing, and the other end of the transmission rod is installed at the center of one end of the inner cavity of the cooling tank via a bearing.

[0011] In one preferred embodiment, one side of the hollow copper plate is connected through to one end of the cooling connecting telescopic hose, and the hollow copper plate and the cooling copper pipe are interconnected with the interior of the cooling connecting telescopic hose.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the motor is started by an external controller, which drives the transmission shaft to rotate and simultaneously drives the fixed ring and the stirring plate to rotate. During the rotation of the stirring plate, the liquid material is agitated to accelerate the evaporation process. This avoids the phenomenon of low evaporation efficiency in some 1,4-butenediol evaporation and concentration circulating mixing devices when evaporating materials because there is no agitation device inside.

[0014] 2. In this invention, an external controller starts a delivery pump to deliver coolant to the interior of the cooling copper tube via a telescopic hose, thereby cooling its surface. The external controller then starts a forward / reverse motor, which drives the transmission rod and hollow copper plate to rotate, simultaneously rotating the cooling copper tube. This ensures that the surface of the cooling copper tube makes full contact with the evaporating material. The cooled and concentrated 1,4-butenediol is then transported to a storage tank through a discharge pipe. This design avoids the problem in some 1,4-butenediol evaporation and concentration circulating mixing devices where the fixed position of the cooling copper tube prevents it from quickly and fully contacting the evaporating material during the cooling and concentration process.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a 1,4-butenediol evaporation and concentration circulating mixed flow device, comprising: a base plate 1, four pillars 101 are equidistantly installed at one end of the top of the base plate 1, a heating evaporation tank 104 is installed on the top of the four pillars 101, a stirring device 2 is provided in the inner cavity of the heating evaporation tank 104, a feed inlet 107 is fixedly inserted through the top of the surface of the heating evaporation tank 104, a support plate 102 is installed at the other end of the top of the base plate 1, a cooling tank 103 is installed on the top of the support plate 102, a cooling device 3 is provided in the inner cavity of the cooling tank 103, and a discharge pipe 108 is fixedly inserted through the bottom of one end of the cooling tank 103.

[0023] Specifically: the liquid material in the inner cavity of the heated evaporation tank 104 is stirred by the stirring device 2 to evaporate it faster, and then the evaporated material is cooled and concentrated by the cooling device 3.

[0024] In one embodiment, a pressure relief port 106 is provided on one side of the top of the heating evaporation tank 104, and a connecting pipe 105 is fixedly inserted through the other side of the top of the heating evaporation tank 104. One end of the connecting pipe 105 is fixedly inserted through the top of the other end of the cooling tank 103, and a cooling connecting telescopic hose 109 is inserted and connected through one end of the cooling tank 103.

[0025] Specifically: the pressure inside the heating evaporator 104 is prevented from being too high through the pressure relief port 106, and the connecting pipe 105 is used for conveying and pressure relief.

[0026] In one embodiment, the stirring device 2 includes a motor 201, the output end of which is fixedly connected to a drive shaft 202, and three fixing rings 203 are equidistantly mounted on the surface of the drive shaft 202, and a plurality of stirring plates 204 are equidistantly mounted around the surface of the three fixing rings 203.

[0027] Specifically: the motor 201 drives the stirring plate 204 to stir, so that the liquid material can be fully evaporated, which can accelerate the evaporation.

[0028] In one embodiment, the top of the motor 201 is mounted at the center of the bottom of the heating evaporation tank 104, the bottom end of the surface of the drive shaft 202 is mounted through a sealed bearing at the center of the bottom of the inner cavity of the heating evaporation tank 104, and the top end of the drive shaft 202 is mounted through a bearing at the center of the top of the inner cavity of the heating evaporation tank 104.

[0029] Specifically, the motor 201 and the drive shaft 202 are fixed and connected through the heated evaporation tank 104, thus achieving the function of fixing and connecting.

[0030] In one embodiment, the cooling device 3 includes a forward and reverse motor 301, the output end of which is fixedly connected to a transmission rod 302, and hollow copper plates 303 are installed at both ends of the surface of the transmission rod 302. Cooling copper pipes 304 are installed equidistantly around the opposite sides of the two hollow copper plates 303.

[0031] Specifically: The forward and reverse motor 301 drives the cooling copper pipe 304 to rotate half a circle in both directions, so that the evaporating material can be fully contacted and cooled, thus achieving the effect of full contact cooling.

[0032] In one embodiment, one end of the forward and reverse motor 301 is installed at the center of one end of the cooling tank 103, one end of the surface of the transmission rod 302 passes through one end of the cooling tank 103 through a seal, and the other end of the transmission rod 302 is installed at the center of one end of the inner cavity of the cooling tank 103 through a bearing.

[0033] Specifically, the cooling tank 103 fixes the forward and reverse motor 301 and the transmission rod 302, thus achieving a fixing effect.

[0034] In one embodiment, one side of a hollow copper plate 303 is connected through to one end of a cooling connection telescopic hose 109, and the hollow copper plate 303 and the cooling copper pipe 304 are interconnected with the interior of the cooling connection telescopic hose 109.

[0035] Specifically: the cooled and connected flexible hose 109 connects to the hollow copper plate 303, thus serving as a connection.

[0036] Working principle: When evaporating 1,4-butenediol, motor 201 and forward / reverse motor 301 are electrically connected to an external controller. One end of the cooling connection telescopic hose 109 is connected to the output end of an external delivery pump. The external delivery pump can connect to the interior of an external coolant container through a delivery pipe, and the coolant is delivered by the delivery pump. The feed inlet 107 connects to an external liquid 1,4-butenediol raw material delivery pipe. Liquid material is delivered to the inner cavity of the heating evaporation tank 104 through the feed inlet 107 for heating and evaporation. Then, the external controller starts motor 201, which drives the drive shaft 202 to rotate, and at the same time drives the fixed ring 203 and the stirring plate 204 to rotate. During the rotation of the stirring plate 204, the liquid material is turned over to accelerate the evaporation process, avoiding the phenomenon of low evaporation efficiency in some 1,4-butenediol evaporation and concentration circulating mixed flow devices when evaporating materials due to the lack of internal turning equipment.

[0037] When cooling and concentrating the evaporated material, an external controller starts a delivery pump to deliver coolant to the interior of the cooling copper tube 304 via the cooling connection telescopic hose 109, thereby cooling its surface. Then, the external controller starts a forward and reverse motor 301, which drives the transmission rod 302 and the hollow copper plate 303 to rotate, thereby rotating the cooling copper tube 304. This ensures that the surface of the cooling copper tube 304 makes full contact with the evaporated material. The cooled and concentrated 1,4-butenediol is then transported to a storage tank for storage through the discharge pipe 108. This also avoids the situation in some 1,4-butenediol evaporation and concentration circulating mixing devices where the cooling copper tube 304 is fixed in position, preventing it from making sufficient contact with the evaporated material more quickly.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
