Description

Technical Field

[0001] The invention belongs to the technical field of refrigerant production, and in particular is a preparation device for refrigerant production. Background Art

[0002] Refrigerant plays an important role in transferring cold in the refrigeration system. Selecting high-quality refrigerant is crucial to the stability and life of the equipment.

[0003] At present, the refrigerant used under conditions below 0°C is usually an aqueous solution of sodium chloride or calcium chloride salts, or an aqueous solution of organic compounds such as ethylene glycol or propylene glycol. Therefore, the refrigerant used under conditions below 0°C needs to be separately configured. In the prior art, when configuring the refrigerant, various refrigerant raw materials need to be placed inside a configuration container, and then the various refrigerant raw materials are stirred with the help of a stirring mechanism to allow the various refrigerant raw materials to be fully mixed. However, the existing stirring mechanism has a relatively single stirring method for the refrigerant raw materials (for example, a single horizontal stirring using a stirring blade, or a single vertical stirring using a stirring screw). The single stirring method will result in a longer mixing time for the refrigerant raw materials, thereby making the refrigerant configuration efficiency relatively low. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a preparation device for producing a secondary refrigerant.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

While the stirring component is moving in a circular motion, the second driving component is used to drive the stirring component to move radially along the preparation tank, thereby radially stirring the various refrigerant raw materials. In this way, the various refrigerant raw materials inside the preparation tank can obtain a double stirring effect, thereby improving the mixing effect of the various refrigerant raw materials, and thereby improving the configuration effect of the refrigerant.

DETAILED DESCRIPTION

[0033] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] See also Figure 1 as well as Figure 2 The present embodiment provides a preparation device for producing a refrigerant, comprising a preparation tank 10, a first drive assembly 20, a stirring assembly 30 and a second drive assembly 40. A feed pipe 101 is arranged on the top of the preparation tank 10, and the stirring assembly 30 is arranged inside the preparation tank 10. The first drive assembly 20 is installed on the side wall of the preparation tank 10, and is used to drive the stirring assembly 30 to move in a circular motion along the inside of the preparation tank 10 to circumferentially stir the refrigerant raw material. The second drive assembly 40 is movably arranged on the inner wall of the preparation tank 10. When the stirring assembly 30 moves in a circular motion, the second drive assembly 40 is used to drive the stirring assembly 30 to move radially along the preparation tank 10 to radially stir the refrigerant raw material.

[0036] When it is necessary to configure the refrigerant, various refrigerant raw materials can be introduced into the preparation tank 10 from the feed pipe 101, and then the first drive component 20 is used to drive the stirring component 30 to move in a circular motion inside the preparation tank 10, thereby circumferentially stirring the various refrigerant raw materials. While the stirring component 30 is moving in a circular motion, the second drive component 40 drives the stirring component 30 to move radially along the preparation tank 10, thereby radially stirring the various refrigerant raw materials. In this way, the various refrigerant raw materials inside the preparation tank 10 can obtain a double stirring effect, thereby improving the mixing effect of the various refrigerant raw materials, and then improving the configuration effect of the refrigerant.

[0037] See also Figure 1 In one embodiment, the first driving component 20 includes a motor 201 and a rotating shaft 202, wherein the motor 201 is fixedly mounted on the upper portion of the preparation tank 10, one end of the rotating shaft 202 is connected to the output end of the motor 201, and the other end extends into the interior of the preparation tank 10 and is distributed along the axial direction of the preparation tank 10, the stirring component 30 includes a stirring vertical rod 301 and a stirring horizontal rod 302, the stirring horizontal rod 302 is provided with a plurality of groups, a plurality of the stirring horizontal rods 302 are fixedly mounted on the side wall of the stirring vertical rod 301, and the bottom of the stirring vertical rod 301 is connected to the rotating shaft 202.

[0038] After various refrigerant raw materials are placed inside the preparation tank 10, the motor 201 is started. The motor 201 drives the rotating shaft 202 to rotate, and then drives the stirring vertical rod 301 to perform circular motion around the rotating shaft 202. While the stirring vertical rod 301 moves in a circular motion, it also drives several stirring horizontal rods 302 to perform synchronous circular motion. The stirring vertical rod 301 and several stirring horizontal rods 302 are used to perform circumferential stirring treatment on various refrigerant raw materials inside the preparation tank 10.

[0039] See also Figure 1 , Figure 3 as well as Figure 4In one embodiment, the second driving assembly 40 includes a rotating ring 401 and an arc-shaped protrusion 402, the rotating ring 401 is installed on the inner wall of the preparation tank 10, the arc-shaped protrusion 402 is provided with a plurality of groups, a plurality of the arc-shaped protrusions 402 are fixedly arranged on the inner wall of the rotating ring 401, and a plurality of the arc-shaped protrusions 402 are spaced apart on the inner wall of the rotating ring 401, the stirring assembly 30 also includes a square guide sleeve 303 and a square telescopic rod 304, one end of the square guide sleeve 303 is fixedly connected to the side wall of the rotating shaft 202, and the other end is along the preparation tank 10. The can making machine 10 extends radially, one end of the square telescopic rod 304 extends from one end of the square guide sleeve 303 away from the rotating shaft 202 to the inside of the square guide sleeve 303 and telescopically cooperates with the square guide sleeve 303, and the other end extends to the inside of the rotating ring 401, and a first elastic member 305 for providing elastic support to the square telescopic rod 304 is arranged inside the square guide sleeve 303, a slot 3031 is opened on the square guide sleeve 303, and the stirring vertical rod 301 vertically penetrates the square telescopic rod 304 from the slot 3031.

[0040] When the motor 201 drives the rotating shaft 202 to rotate, the rotating shaft 202 can rotate through the square guide sleeve 303 and the square telescopic rod 304. When the square telescopic rod 304 rotates, it drives the stirring vertical rod 301 and a plurality of stirring horizontal rods 302 to move in a circle around the rotating shaft 202. The stirring vertical rod 301 and the stirring horizontal rod 302 perform circumferential stirring treatment on various coolants. At the same time, during the rotation of the square telescopic rod 304, due to the elastic support of the first elastic member 305, when one end of the square telescopic rod 304 away from the square guide sleeve 303 acts on a group of arc-shaped protrusions 402, the group of arc-shaped protrusions 402 can push the square telescopic rod 304 so that the square telescopic rod 304 moves toward the square guide sleeve 30 3, thereby driving the stirring vertical rod 301 and the plurality of stirring cross rods 302 to approach the rotating shaft 202. When the end of the square telescopic rod 304 away from the square guide sleeve 303 passes over the middle position of the group of arc-shaped protrusions 402, the first elastic member 305 pushes the square telescopic rod 304 to move outside the square guide sleeve 303, thereby driving the stirring vertical rod 301 and the plurality of stirring cross rods 302 to move away from the rotating shaft 202. By the stirring vertical rod 301 and the plurality of stirring cross rods 302 approaching and moving away from the rotating shaft 202, the stirring vertical rod 301 and the stirring cross rod 302 can be moved radially along the preparation tank 10, thereby performing radial stirring treatment on various coolants.

[0041] See also Figure 4In one embodiment, the stirring vertical rod 301 is rotatably matched with the square telescopic rod 304 , a gear 307 is fixedly provided at the bottom of the stirring vertical rod 301 , a rack 306 is fixedly provided at the bottom of the square guide sleeve 303 , and the gear 307 is meshed with the rack 306 .

[0042] When the end of the square telescopic rod 304 away from the square guide sleeve 303 acts on a group of arc-shaped protrusions 402 and drives the stirring vertical rod 301 and the stirring horizontal rod 302 to approach the rotating shaft 202, the stirring vertical rod 301 drives the gear 307 to synchronously approach the rotating shaft 202. At this time, the meshing action of the gear 307 and the rack 306 can drive the stirring vertical rod 301 to rotate compared with the square telescopic rod 304, and the stirring vertical rod 301 drives a plurality of stirring horizontal rods 302 to rotate synchronously. When the end of the square telescopic rod 304 away from the square guide sleeve 303 passes through the middle position of a group of arc-shaped protrusions 402, the first elastic member 305 pushes the square telescopic rod 304. The stirring vertical rod 301 and the stirring cross rod 302 are moved away from the rotating shaft 202, and the stirring vertical rod 301 drives the gear 307 to synchronously move away from the rotating shaft 202. At this time, the reverse meshing action of the gear 307 and the rack 306 is utilized to drive the stirring vertical rod 301 to rotate in the opposite direction compared with the square telescopic rod 304. The stirring vertical rod 301 drives several stirring cross rods 302 to rotate in the opposite direction synchronously. In this way, when the stirring vertical rod 301 and the stirring cross rod 302 move radially along the preparation tank 10 to radially stir various refrigerant raw materials, the stirring vertical rod 301 can also drive several stirring cross rods 302 to rotate on their own, thereby further improving the stirring effect of various refrigerant raw materials.

[0043] When the square telescopic rod 304 acts on a certain group of arc-shaped protrusions 402, the first elastic member 305 can realize the radial movement of the stirring vertical rod 301 and the stirring horizontal rod 302. However, since the position of the arc-shaped protrusions 402 is relatively fixed, the paths of the stirring vertical rod 301 and the stirring horizontal rod 302 when they move radially are relatively fixed, so that the stirring vertical rod 301 and the stirring horizontal rod 302 cannot fully stir the coolant raw material inside the preparation tank 10, and the coolant raw material is prone to have a stirring dead angle. To avoid this phenomenon, please refer to Figure 2In one embodiment, the rotating ring 401 is rotatably mounted on the inner wall of the preparation tank 10, and a third driving assembly 50 is further provided inside the preparation tank 10. After the stirring vertical rod 301 and the stirring horizontal rod 302 make a circular motion inside the preparation tank 10, the third driving assembly 50 is used to drive the rotating ring 401 to rotate, and then drive the plurality of arc-shaped protrusions 402 to rotate, so as to adjust the positions of the plurality of arc-shaped protrusions 402, so that the plurality of arc-shaped protrusions 402 can provide support for the square telescopic rod 304 from different positions, thereby changing the radial movement paths of the stirring vertical rod 301 and the stirring horizontal rod 302 in the next circular motion cycle, thereby comprehensively stirring various refrigerant raw materials to further improve the configuration effect of the refrigerant raw materials.

[0044] See also Figure 1 , Figure 3 as well as Figure 5 In one embodiment, an annular guide rail 103 is fixedly provided on the inner wall of the preparation tank 10, an annular notch 403 is provided on the outer wall of the rotating ring 401, the annular guide rail 103 extends into the inside of the annular notch 403 and rotates with the rotating ring 401, a plurality of spaced limiting teeth 1031 are fixedly provided on the inner wall of the annular guide rail 103, a through hole 404 communicating with the annular notch 403 is provided on the inner wall of the rotating ring 401, and the third driving assembly 50 includes a limiting piece 5 01 and a second elastic member 503, the limiting plate 501 is a bent structure, one end of the limiting plate 501 extends between two adjacent groups of the limiting teeth 1031, and the other end extends from the through hole 404 to the inner side of the rotating ring 401, and the side wall of the limiting plate 501 is rotatably connected to the inner wall of the through hole 404 through a pin rod 502, one end of the second elastic member 503 is connected to the inner wall of the through hole 404, and the other end is connected to the limiting plate 501, which is used to provide elastic support for the limiting plate 501.

[0045] When one end of the square telescopic rod 304 away from the square guide sleeve 303 acts on a group of arc-shaped protrusions 402, one end of the limiting piece 501 is inserted between two adjacent groups of limiting teeth 1031 under the elastic support of the second elastic member 503, thereby realizing the limiting of the rotating ring 401 and the arc-shaped protrusion 402, so that the arc-shaped protrusion 402 can stably provide support for the square telescopic rod 304, and then push the square telescopic rod 304 to move inside the square guide sleeve 303, so that the stirring vertical rod 301 and the stirring horizontal rod 302 can stably move radially. After the stirring vertical rod 301 and the stirring horizontal rod 302 have made a circular motion, the end of the square telescopic rod 304 away from the square guide sleeve 303 acts on the end of the limiting plate 501 located on the inner side of the rotating ring 401, thereby pushing the limiting plate 501 to make the limiting plate 501 rotate relative to the pin rod 502. Since the limiting plate 501 is a bent structure, when the limiting plate 501 rotates, the end of the limiting plate 501 inserted between two adjacent sets of limiting teeth 1031 is removed from between the current two sets of limiting teeth 1031 to release the limiting state of the rotating ring 401. 4 continues to rotate, the square telescopic rod 304 pushes the limiting piece 501 and then drives the rotating ring 401 to rotate relative to the annular guide rail 103, and the rotating ring 401 drives the plurality of arc-shaped protrusions 402 to rotate, thereby changing the positions of the plurality of arc-shaped protrusions 402. After the plurality of arc-shaped protrusions 402 rotate a certain angle, as the limiting piece 501 continues to rotate relative to the pin rod 502, one end of the limiting piece 501 located on the inner side of the rotating ring 401 slides relative to the square telescopic rod 304, the limiting piece 501 gradually separates from the square telescopic rod 304, and the square telescopic rod 304 passes over The limiting plate 501 and the second elastic member 503 push the limiting plate 501 so that the limiting plate 501 rotates in the opposite direction compared to the pin rod 502, and the other end of the limiting plate 501 is reinserted between two adjacent groups of limiting teeth 1031, thereby re-limiting the rotating ring 401 and the plurality of arc-shaped protrusions 402, and the square telescopic rod 304 is continuously pushed by the plurality of arc-shaped protrusions 402 whose positions are changed in the subsequent circular motion cycle, thereby driving the stirring vertical rod 301 and the stirring horizontal rod 302 to move radially along different paths, thereby realizing comprehensive stirring of the coolant raw material.

[0046] In one embodiment, the first elastic member 305 and the second elastic member 503 may be springs or metal springs, which are not limited herein.

[0047] See also Figure 1 In one embodiment, a discharge pipe 102 is provided at the bottom of the preparation tank 10, and a discharge valve (not shown in the figure) is provided inside the discharge pipe 102. After the coolant is prepared, the discharge valve can be opened to discharge the coolant inside the preparation tank 10 from the discharge pipe 102.

[0048] In an embodiment of the present invention, when it is necessary to configure the refrigerant, various refrigerant raw materials can be introduced into the preparation tank 10 from the feed pipe 101, and then the first drive component 20 is used to drive the stirring component 30 to move in a circular motion inside the preparation tank 10, thereby circumferentially stirring the various refrigerant raw materials. While the stirring component 30 is moving in a circular motion, the second drive component 40 drives the stirring component 30 to move radially along the preparation tank 10, thereby radially stirring the various refrigerant raw materials. In this way, the various refrigerant raw materials inside the preparation tank 10 can obtain a double stirring effect, thereby improving the mixing effect of the various refrigerant raw materials, and thereby improving the configuration effect of the refrigerant. Compared with the prior art, when configuring the refrigerant, various refrigerant raw materials can be double stirred, thereby improving the mixing effect of the various refrigerant raw materials, and improving the configuration effect and efficiency of the refrigerant.

Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
