Description

Technical Field

[0001] This utility model belongs to the field of xylene production technology, and specifically relates to a cooling device. Background Technology

[0002] Xylene is an important organic chemical raw material, widely used in coatings, resins, dyes, pharmaceuticals and pesticides. It is mainly extracted or synthesized from aromatic fractions in petroleum and coal tar. In the process of xylene production, cooling devices are required to precisely control the xylene temperature in order to maintain reaction efficiency or separation purity.

[0003] Existing cooling devices involve adding the raw xylene solution to be cooled into the cooling cylinder, then starting a motor to drive a connected stirring shaft. A stirring paddle on the outer arc surface of the stirring shaft agitates the solution, and cooling pipes installed on the inner wall of the cooling cylinder rapidly and uniformly cool the agitated solution. However, in actual use, because the amount of xylene solution requiring cooling at one time during production is large, the cooling cylinder needs to cool a significant amount of xylene solution, resulting in a long cooling time and poor cooling effect. This slows down the xylene production rate and affects processing efficiency. Utility Model Content

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a cooling device that can continuously and rapidly cool xylene stock solution by extending the flow path of the xylene stock solution within the cooling cylinder and by cooperating with a stirring paddle.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cooling device, including a cooling cylinder, wherein multiple evenly distributed partitions 1 and 2 are arranged inside the cooling cylinder, and partitions 1 and 2 are fitted together. Multiple evenly distributed cooling pipes are arranged on partitions 1 and 2. Multiple evenly distributed stirring shafts are arranged inside the cooling cylinder, and stirring paddles are fixedly sleeved in the middle of the outer arc surface of each stirring shaft. Symmetrically distributed connecting pipe groups are arranged on the outside of the cooling cylinder, and the cooling pipes are respectively connected to adjacent connecting pipe groups. Symmetrically distributed connecting boxes are arranged on the outside of the cooling cylinder, and connecting pipes are arranged between the connecting boxes and the connecting pipe groups. A bracket is fixedly installed on the outside of the cooling cylinder by bolts, and rubber pads are arranged at the four corners of the lower end of the bracket.

[0006] As a further improvement of this utility model, a drive box is provided on the cooling cylinder. Multiple evenly distributed rotating shafts are rotatably arranged inside the drive box. The rotating shafts are fixed to adjacent stirring shafts by couplings. Worm wheels are fixedly sleeved on the outer arc surface of each rotating shaft. Multiple evenly distributed rotating seats are provided inside the drive box. Worms are rotatably arranged between adjacent rotating seats. The worms are meshed with adjacent worm wheels. Multiple dual-axis motors are provided inside the drive box. The output shafts of the dual-axis motors are fixed to adjacent worms by couplings.

[0007] As a further improvement of this utility model, a solenoid valve one is provided at the liquid inlet pipe at the upper end of the cooling cylinder, and a solenoid valve two is provided at the liquid outlet pipe at the lower end of the cooling cylinder.

[0008] As a further improvement of this utility model, a control box is provided on the outside of the cooling cylinder, and solenoid valve one, solenoid valve two and the dual-axis motor are all electrically connected to the control box.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the cooled xylene stock solution enters through the inlet pipe and then flows downward between partition one and partition two. The cooperation between partition one and partition two extends the flow path of the xylene stock solution, allowing it to be cooled quickly and thoroughly.

[0011] Secondly, the coolant enters the interior of the connecting pipe assembly through the connecting pipe on one side, and then enters the interior of the connecting pipe assembly on the other side through the cooling pipe, and is discharged from the connecting pipe on the other side, so that the coolant flows inside the cooling pipe and cools the xylene stock solution through the cooling pipes evenly arranged on the first and second partitions.

[0012] Third, the dual-shaft motor is controlled by the control box. The meshing relationship between the worm and the worm wheel drives the worm wheel to rotate, which in turn drives the stirring shaft to rotate. This causes the stirring paddle on the outer arc surface of the stirring shaft to rotate, which helps to rapidly cool the xylene stock solution.

[0013] Fourth, the rubber pads at the four corners of the lower surface of the bracket can buffer the bottom of the bracket, which can effectively prevent the bottom of the bracket from being damaged due to the pressure of the cooling cylinder on the bracket for a long time.

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 3 As shown, the device includes a cooling cylinder 101. Inside the cooling cylinder 101 are multiple evenly distributed partitions 201 and 202, which are fitted together and spaced apart. Multiple evenly distributed cooling pipes 203 are provided on both partitions 201 and 202. Inside the cooling cylinder 101 are multiple evenly distributed stirring shafts 204, each with a stirring paddle 205 fixedly fitted onto its outer arc surface. A drive box 209 is mounted on the cooling cylinder 101. The drive housing 209 has multiple evenly distributed rotating shafts 210, which are fixed to adjacent stirring shafts 204 via couplings. Worm gears 211 are fixedly sleeved on the outer arc surface of each rotating shaft 210. The drive housing 209 has multiple evenly distributed rotating seats 212, and worm gears 213 are rotatably mounted between adjacent rotating seats 212. The worm gears 213 are meshed with adjacent worm gears 211. The drive housing 209 also has multiple dual-shaft motors 214, whose output shafts are fixed to adjacent worm gears 213 via couplings.

[0022] like Figure 1 , 3As shown, symmetrically distributed connecting pipe groups 207 are provided on the outer side of the cooling cylinder 101, and the cooling pipes 203 are respectively connected to the adjacent connecting pipe groups 207. Symmetrically distributed connecting boxes 206 are provided on the outer side of the cooling cylinder 101, and connecting pipes 208 are provided between the connecting boxes 206 and the connecting pipe groups 207.

[0023] like Figure 1 , 4 As shown, a solenoid valve 104 is installed at the liquid inlet pipe at the upper end of the cooling cylinder 101, and a solenoid valve 105 is installed at the liquid outlet pipe at the lower end of the cooling cylinder 101.

[0024] like Figure 1 , 4 As shown, a control box 301 is provided on the outside of the cooling cylinder 101. Solenoid valve 104, solenoid valve 205 and dual-axis motor 214 are all electrically connected to the control box 301.

[0025] In use, the connecting pipes 208 are connected to the external coolant pipes respectively, so that the coolant enters the interior of the connecting pipe assembly 207 through the connecting pipe 208 on one side, enters the cooling pipe 203 through the connecting pipe assembly 207, and then enters the interior of the connecting pipe assembly 207 on the other side through the cooling pipe 203, and is discharged from the connecting pipe 208 on the other side, so that the coolant flows inside the cooling pipe 203.

[0026] The dual-axis motor 214 is controlled by the control box 301, which causes the output shaft of the dual-axis motor 214 to drive the worm 213 connected to it to rotate. Through the meshing relationship between the worm 213 and the worm wheel 211, the worm wheel 211 is driven to rotate. The worm wheel 211 drives the stirring shaft 204 to rotate through the rotating shaft 210, which causes the stirring paddle 205 on the outer arc surface of the stirring shaft 204 to rotate.

[0027] The control box 301 regulates the operation of solenoid valve 104 and solenoid valve 105, opening the inlet and outlet pipes, allowing the xylene stock solution to be cooled to enter through the inlet pipe and then flow downwards between partition 1 201 and partition 2 202. The flow path of the xylene stock solution is extended by the cooperation of partition 1 201 and partition 2 202, and the xylene stock solution is cooled by the cooling pipes 203 evenly arranged on partition 1 201 and partition 2 202. During the flow process, the rotating agitator 205 assists in the rapid cooling of the xylene stock solution.

[0028] According to another embodiment of the present invention, such as Figure 1 , 2As shown, a bracket 102 is bolted to the outside of the cooling cylinder 101, and rubber pads are provided at the four corners of the lower end of the bracket 102. During use, the rubber pads at the four corners of the lower surface of the bracket 102 can buffer the bottom end of the bracket 102, which can effectively prevent the bottom end of the bracket 102 from being damaged due to the pressure of the cooling cylinder 101 on the bracket 102 for a long time.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
