Description

Technical Field

[0001] This utility model belongs to the field of styrene refrigeration technology, and specifically relates to a styrene refrigeration cycle device. Background Technology

[0002] During the storage of styrene, when the ambient temperature is too high, styrene in the storage tank will polymerize, resulting in excessive levels of styrene polymers in the tank. To prevent styrene from polymerizing, a refrigeration circulation device is usually installed in the styrene storage tank.

[0003] In existing technologies, when a refrigeration circulation device is installed inside a styrene storage tank to deliver cold air into the tank, the flow rate of the cold air delivery cannot be controlled. This results in insufficient precision in controlling the temperature inside the styrene storage tank, leading to poor storage performance and hindering its use.

[0004] Therefore, a styrene refrigeration cycle device is needed to solve the problem that most existing technologies cannot control the flow rate of cold air delivery, resulting in insufficient precision in temperature control inside styrene storage tanks and thus poor styrene storage performance. Utility Model Content

[0005] The purpose of this invention is to provide a styrene refrigeration cycle device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a styrene refrigeration cycle device, comprising a styrene storage tank body, an air inlet pipe connected to and fixed to the top of the styrene storage tank body, a connecting seat connected to and fixed to the top of the air inlet pipe, a connecting pipe disposed on the top of the connecting seat, and a variable diameter filter mechanism for controlling the aperture at the middle position of the connecting seat.

[0007] The variable diameter filter mechanism includes a rotating disk rotatably connected to the inner cavity of the connecting seat, an inner ring fixed to the inner cavity of the connecting seat at the top position of the rotating disk, connecting strips fixed to the outer circumferential surface of the inner ring and arranged in an equidistant ring, a plurality of valve blocks arranged in an equidistant ring at the bottom of the inner ring and a drive assembly acting on the valve blocks, wherein the end of the connecting strip away from the inner ring is fixed to the inner wall of the connecting seat.

[0008] It should be noted in the solution that the driving component includes a limiting groove that extends through the surface of the connecting strip and a limiting rod that is slidably inserted into the limiting groove.

[0009] It is further worth noting that the drive assembly also includes a hexagonal groove formed on the top surface of the rotating disk and a plurality of drive blocks slidably inserted into the cavity of the hexagonal groove.

[0010] Furthermore, it should be noted that the top of the drive block is fixed to the surface of the bottom of the adjacent valve block, and the bottom of the limiting rod is fixed to the surface of the adjacent valve block.

[0011] In a preferred embodiment, the drive assembly further includes an opening at one end of the connecting seat, a connecting plate fixed to one end of the outer peripheral surface of the connecting seat, and hydraulic cylinders fixed to both sides of the opening of the connecting seat.

[0012] In a preferred embodiment, the variable diameter filter mechanism further includes a mounting component acting on the connecting seat, the mounting component including a threaded section disposed on the top of the inner circumferential surface of the connecting seat.

[0013] In a preferred embodiment, the mounting assembly further includes a threaded ring fixed to the bottom of the connecting pipe and a filter screen fixed to the inner cavity of the connecting pipe.

[0014] Compared with the prior art, the styrene refrigeration cycle device provided by this utility model has at least the following beneficial effects:

[0015] (1) By controlling two hydraulic cylinders, the rotating disk can be rotated, and the distance between multiple valve blocks can be changed under the action of the hexagonal groove and the drive block, thereby controlling the size of the hole at the middle position of the connecting seat, so as to facilitate the adjustment of the flow rate of cold air delivery according to the actual needs, thereby facilitating the control of the styrene storage effect, thus improving the applicability of the device.

[0016] (2) The connection between the threaded ring and the threaded section makes it easy for the user to connect the connecting pipe to the connecting seat. The filter screen can filter the air before it enters the connecting seat, thereby preventing external dust from entering the interior of the styrene storage tank, thus further improving the applicability of the device.

Detailed Implementation

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will be apparent to those skilled in the art.

[0024] Example 1

[0025] Please see Figure 1-5 This utility model provides a styrene refrigeration cycle device, including a styrene storage tank body 1, an air inlet pipe 2 connected and fixed to the top of the styrene storage tank body 1, a connecting seat 4 connected and fixed to the top of the air inlet pipe 2, a connecting pipe 3 set on the top of the connecting seat 4, and a variable diameter filter mechanism for controlling the aperture at the middle position of the connecting seat 4.

[0026] The variable diameter filter mechanism includes a rotating disk 9 rotatably connected to the inner cavity of the connecting seat 4, an inner ring body 13 fixed to the top of the rotating disk 9 in the inner cavity of the connecting seat 4, connecting strips 14 fixed to the outer circumference of the inner ring body 13 and arranged in an equidistant ring, multiple valve blocks 15 arranged in an equidistant ring at the bottom of the inner ring body 13, and a drive assembly acting on the valve blocks 15. The end of the connecting strip 14 away from the inner ring body 13 is fixed to the inner wall of the connecting seat 4.

[0027] When the connecting pipe 3 is fixed to the top of the connecting seat 4 and connected to the inner cavity of the connecting seat 4, a pipe capable of conveying cold air is connected to the outside of the connecting seat 4. This allows the cold air to enter the interior of the styrene storage tank body 1 through the connecting pipe 3, the connecting seat 4 and the air inlet pipe 2. When it is necessary to control the orifice diameter of the inner cavity of the connecting seat 4, the rotating disk 9 is rotated by the drive assembly, thereby changing the spacing between the multiple valve blocks 15 and thus controlling the orifice diameter between the multiple valve blocks 15. This allows for easy adjustment of the flow rate of the cold air delivery according to actual needs, thereby facilitating the control of the styrene storage effect.

[0028] Please see Figure 1-5The drive assembly includes a limiting groove 16 extending through the surface of the connecting strip 14, a limiting rod 17 slidably inserted into the limiting groove 16, a hexagonal groove 18 extending on the top surface of the rotating disk 9, and a plurality of drive blocks 7 slidably inserted into the cavity of the hexagonal groove 18. The top of the drive block 7 is fixed to the bottom surface of the adjacent valve block 15, and the bottom of the limiting rod 17 is fixed to the surface of the adjacent valve block 15.

[0029] When it is necessary to adjust the spacing between multiple valve blocks 15, the rotating disk 9 is rotated, so that the inner cavity of the hexagonal groove 18 abuts against multiple driving blocks 7, causing them to slide. Due to the limiting effect of the contact between the surface of the limiting rod 17 and the inner wall of the limiting groove 16, the driving block 7 drives multiple valve blocks 15 to move closer to or further away from each other, thereby adjusting the aperture formed between multiple valve blocks 15.

[0030] Please see Figure 1-5 The drive assembly also includes an opening 10 at one end of the connecting seat 4, a connecting plate 11 fixed to one end of the outer peripheral surface of the connecting seat 4, and hydraulic cylinders 12 fixed to both sides of the opening 10 of the connecting seat 4.

[0031] By controlling the extension or retraction of the output ends of the two hydraulic cylinders 12, the output ends of the hydraulic cylinders 12 can abut against the connecting plate 11, causing the connecting plate 11 to drive the rotating disk 9 to rotate within the cavity of the connecting seat 4.

[0032] Example 2

[0033] Please see Figure 1-5 The variable diameter filter mechanism also includes an installation component that acts on the connecting seat 4. The installation component includes a threaded section 5 disposed on the top of the inner circumferential surface of the connecting seat 4, a threaded ring 6 fixed to the bottom of the threaded section 5, and a filter screen 8 fixed to the inner cavity of the connecting pipe 3.

[0034] By placing the threaded ring 6 on the top of the threaded section 5 and rotating the connecting pipe 3, the connecting pipe 3 can be connected to the connecting seat 4, and the inner cavity of the connecting pipe 3 can be connected to the inner cavity of the connecting seat 4. The filter screen 8 can prevent dust and other contaminants contained in the cold air transported by the connecting pipe 3 from being intercepted by the filter screen 8, thereby preventing dust from entering the inner cavity of the styrene storage tank body 1. Furthermore, by replacing the connecting pipe 3, it can be ensured that the connecting pipe 3 still has a good dustproof effect during long-term use.

[0035] Working principle: By setting the threaded ring 6 at the top of the threaded section 5 and rotating the connecting pipe 3, the connecting pipe 3 and the connecting seat 4 can be connected, making the inner cavity of the connecting pipe 3 and the inner cavity of the connecting seat 4 interconnected. The filter screen 8 prevents dust and other contaminants in the cold air transported by the connecting pipe 3 from being intercepted, thus preventing dust from entering the inner cavity of the styrene storage tank body 1. When it is necessary to control the flow rate of cold air entering the inner cavity of the styrene storage tank body 1, this can be achieved by controlling the orifice diameter of the inner cavity of the connecting seat 4. Firstly, the output ends of the two hydraulic cylinders 12 need to be extended or retracted, so that the output ends of the hydraulic cylinders 12 can... The contact plate 11 causes the rotating disk 9 to rotate within the cavity of the connecting seat 4, thereby causing the inner cavity of the hexagonal groove 18 to contact and slide against the multiple driving blocks 7. Due to the limiting effect of the contact between the surface of the limiting rod 17 and the inner wall of the limiting groove 16, the driving block 7 drives the multiple valve blocks 15 to move towards or away from each other, thereby adjusting the aperture formed between the multiple valve blocks 15 and controlling the aperture size at the middle position of the connecting seat. This allows for easy adjustment of the flow rate of cold air delivery according to actual needs, thus facilitating the control of the styrene storage effect.
