[0023] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification. Embodiment

[0024] Referring to Figures 1 - 3 , as the first embodiment of the present utility model, a rapid cooling device for the working hot zone of a hot isostatic press is provided. This rapid cooling device for the working hot zone of a hot isostatic press includes a static pressure cylinder 1, a cooler 2, and a circulating liquid tank 3. A spray pipe 4 is connected between the circulating liquid tank 3 and the static pressure cylinder 1. It also includes a return pipe 5 connected to the static pressure cylinder 1 and the circulating liquid tank 3. A vibration filtering mechanism 6 is provided in the return pipe 5, and a sewage collection tank 7 is fixedly connected to the return pipe 5.

[0025] In the above technical solution, when the return pipe 5 conveys the coolant into the circulation liquid tank 3, the vibration filtering mechanism 6 can intercept the impurities in the coolant to prevent the impurities from entering the circulation liquid tank 3. When the vibration filtering mechanism 6 vibrates, the intercepted impurities can be shaken off and precipitated into the dirt collection tank 7. The impurities can be removed by disassembling the dirt collection tank 7.

[0026] The vibration filtering mechanism 6 includes a connecting ring 601 slidably connected to the inner wall of the return pipe 5. One side of the connecting ring 601 is fixedly connected with a filter net 602. The vibration filtering mechanism 6 further includes a motor 603 for driving the connecting ring 601 to reciprocate.

[0027] In the above technical solution, when the motor 603 drives the connecting ring 601 to reciprocate rapidly, the filter net 602 generates vibration, so that the impurities on the filter net 602 can be shaken off and precipitated into the dirt collection tank 7.

[0028] During the actual working process, a solenoid valve is installed at one end of the return pipe 5 close to the static pressure cylinder 1. The solenoid valve controls the opening and closing state of the flow in the return pipe 5. A water pump and a delivery pump are arranged in the circulation liquid tank 3. The water pump is connected to the return pipe 5, and the delivery pump is connected to the spray pipe 4.

[0029] The motor 603 is fixedly installed on one side of the circulation liquid tank 3, and the output shaft of the motor 603 penetrates into the return pipe 5 and is fixedly connected with a crankshaft 604. One end of the crankshaft 604 is hinged with a pull rod 605, and one end of the pull rod 605 is hinged with a connecting rod 606. The connecting rod 606 is fixedly connected with the connecting ring 601.

[0030] In the above technical solution, when the motor 603 drives the crankshaft 604 to rotate, the crankshaft 604 and the pull rod 605 cooperate to drive the connecting rod 606 to move, so that the connecting ring 601 slides rapidly back and forth in the return pipe 5.

[0031] The dirt collection tank 7 includes a guide cover 701, and a dirt collection cylinder 702 is threadedly connected to the guide cover 701.

[0032] In the above technical solution, the impurities falling on the filter net 602 gradually precipitate in the coolant and fall into the guide cover 701. Under the limitation of the guide cover 701, the impurities gather in the dirt collection cylinder 702. The dirt collection cylinder 702 can be removed from the guide cover 701 by rotation, so as to remove the impurities.

[0033] During use, after the static pressure cylinder 1 completes one operation, the conveying water pump extracts the coolant in the circulating liquid tank 3 and sprays it into the static pressure cylinder 1 through the spray pipe 4. The solenoid valve is opened, and at the same time, the water pump extracts the coolant in the static pressure cylinder 1, and the coolant flows back into the circulating liquid tank 3 through the return pipe 5. When the coolant passes through the filter screen 602, impurities are intercepted. After the cooling operation is completed, the connecting ring 601 is driven by the motor 603 to reciprocate, causing the filter screen 602 to vibrate and shake off the impurities, so that the impurities finally settle into the sewage collection cylinder 702. By rotating and removing the sewage collection cylinder 702, the collected impurities can be removed. Embodiment

[0034] Refer to Figures 2 - 4 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a sealing component 8 is installed on the guide cover 701. The sealing component 8 includes a plurality of sealing plates 801 arranged at equal intervals. The sealing plates 801 are rotatably connected inside the guide cover 701, and two adjacent sealing plates 801 are in abutting cooperation. Moreover, sealing strips 802 are fixedly connected to both symmetric sides of the guide cover 701, and the sealing strips 802 are in abutting cooperation with the sealing plates 801.

[0035] In the above technical solution, when the sealing plate 801 is vertically arranged, the upper and lower parts of the guide cover 701 are communicated, so that the impurities in the coolant can precipitate downward. When the sealing plate 801 rotates to the horizontal position, two adjacent sealing plates 801 abut against each other, and the sealing plate 801 on the side is in abutting contact with the sealing strip 802, so that the upper and lower parts of the guide cover 701 are sealed and isolated. At this time, removing the sewage collection cylinder 702 does not affect the normal operation of the return pipe 5.

[0036] Among them, refer to Figure 4 , the sealing plate 801 is rotatably connected to the guide cover 701 through a central rotating shaft, and a sealing ring is provided on the rotating shaft, and the sealing ring is fixedly connected to the guide cover 701.

[0037] The sealing component 8 further includes a bolt 803 rotatably connected to the guide cover 701. A fixing rod 804 is threadedly connected to the bolt 803. Both ends of the fixing rod 804 are fixedly connected with a rack 805. A plurality of gears 806 are meshed with the rack 805, and the gears 806 are coaxially connected and fixed to the sealing plate 801.

[0038] In the above technical solution, the rack 805 is slidably connected to the outer side of the guide cover 701. Rotating the bolt 803 can drive the rack 805 to translate, and the rack 805 cooperates with the gear 806 to drive the sealing plate 801 to rotate.

[0039] It can be understood that refer to Figure 2, a pointer is fixedly connected to the lower end of the rack 805. The guiding plate 701 is located below the pointer and is engraved with the words "open" and "close". When the pointer is above the word "open", the sealing plate 801 is in a vertical state. When the pointer is above the word "close", the sealing plate 801 is in a horizontal state. By matching the pointer with the switch font, the up and down opening and closing states of the guiding cover 701 can be known, avoiding misoperation.

[0040] The remaining structure is the same as that of Embodiment 1.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
