DETAILED DESCRIPTION

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.

[0029] like Figure 1 、 Figure 2 As shown, a refrigerant intermediate temporary storage device includes a collecting barrel 1, a barrel cover 2, an air inlet plate 3, an air outlet plate 4 and a driving mechanism 5.

[0030] like Figure 1 、 Figure 2 As shown, the collection barrel 1 is placed vertically on the ground, and the upper side wall is provided with a feed port 11, and the lower side wall is provided with a discharge port 12. The barrel cover 2 is provided at the upper end of the collection barrel 1, and the barrel cover 2 is provided with an air inlet 21 and an air outlet 22 side by side.

[0031] like Figure 1 、 Figure 2 As shown, the air inlet plate 3 is rotatably connected to the upper end surface of the barrel cover 2, and an air inlet pipe 31 for communicating with the air inlet 21 is provided on the air inlet plate 3. The air outlet plate 4 is rotatably connected to the upper end surface of the barrel cover 2, and an air outlet pipe 41 for communicating with the air outlet 22 is provided on the air outlet plate 4.

[0032] like Figure 1 、 Figure 2 As shown, the driving mechanism 5 is used to control the synchronous rotation of the air inlet plate 3 and the air outlet plate 4. The driving mechanism 5 includes a mounting seat 51, a slide seat 52, a driving rod 53, a gear 54 and a rack 55.

[0033] like Figure 1 、 Figure 2 As shown, the mounting base 51 is vertically mounted on the barrel cover 2, the slide 52 is horizontally slidably connected to the barrel cover 2, and the drive rod 53 is threadedly connected to the mounting base 51 and rotatably connected to the slide 52. A gear 54 is mounted on the outer walls of the air inlet plate 3 and the air outlet plate 4, and a rack 55 is mounted on the slide 52 and meshes with the gear 54.

[0034] When brine storage is required, the drive rod 53 is controlled to rotate. This drives the slide 52 and the rack 55 to move synchronously. The rack 55 then rotates a pair of gears 54, thereby controlling the synchronous rotation of the air inlet plate 3 and the air outlet plate 4. This is until the air inlet pipe 31 on the air inlet plate 3 is connected to the air inlet port 21, and the air outlet pipe 41 on the air outlet plate 4 is also connected to the air outlet port 22.

[0035] Then, a nitrogen cylinder is connected to the air inlet pipe 31, so that nitrogen is filled into the collection barrel 1 and replaces the air in the collection barrel 1, making the collection barrel 1 in an oxygen-free state. Then, the coolant is filled into the collection barrel 1, and during the filling process, nitrogen is constantly introduced to ensure that the collection barrel 1 is in an oxygen-free state.

[0036] After the brine is filled, the drive rod 53 is controlled to rotate in the opposite direction. This causes the slide 52 and the rack 55 to move in the opposite direction. The rack 55 then rotates the pair of gears 54, thereby controlling the synchronous opposite rotation of the air inlet plate 3 and the air outlet plate 4. This is until the air inlet pipe 31 on the air inlet plate 3 is separated from the air inlet port 21 and the air outlet pipe 41 on the air outlet plate 4 is also separated from the air outlet port 22, thus sealing the entire collection barrel 1.

[0037] Therefore, by setting a rotating air inlet plate 3 and an air outlet plate 4, and after rotation, the air inlet pipe 31 and the air outlet pipe 41 are all connected to the interior of the collection barrel 1, at the same time, the nitrogen cylinder is connected to the air inlet pipe 31, so that nitrogen is filled into the collection barrel 1, thereby realizing the replacement of the air in the collection barrel 1, so that after the refrigerant is filled, the collection barrel 1 is ensured to be in an oxygen-free state, thereby realizing stable storage of the refrigerant.

[0038] like Figure 3 As shown, the lid 2 is vertically rotatably connected to a stirring paddle 6 located within the collection barrel 1, thereby stirring the stored brine. On the one hand, this is suitable for storing brine that is prone to sedimentation or precipitation, ensuring the stability of the brine during storage. On the other hand, some brine needs to be mixed or diluted with water during storage, so the stirring paddle 6 can achieve sufficient and uniform stirring of the brine, meeting the production requirements of brine.

[0039] like Figure 3 As shown, the stirring paddle 6 includes a gantry 61 , a rotating tube 62 , a stirring rod 63 , a stirring blade 64 and a control mechanism 7 .

[0040] like Figure 3 As shown, the gantry 61 is arranged on the upper end surface of the barrel cover 2, the rotating tube 62 is vertically rotatably connected between the gantry 61 and the upper end surface of the barrel cover 2, the stirring rod 63 is vertically slidably connected to the rotating tube 62, and the outer wall is provided with a spline 65 that cooperates with the rotating tube 62, and the stirring blade 64 is arranged at the lower end of the stirring rod 63.

[0041] like Figure 3 As shown, the control mechanism 7 is used to control the rotation of the rotating tube 62 and the vertical reciprocating sliding of the stirring rod 63. The control mechanism 7 includes a reciprocating screw 71, a connecting block 72, a motor 73 and a pulley set 74.

[0042] like Figure 3 As shown, a reciprocating screw 71 is vertically connected to the upper end of the gantry 61, and a connecting block 72 is threadedly connected to the reciprocating screw 71 and is rotatably connected to the upper end of the stirring rod 63. A motor 73 is used to control the rotation of the reciprocating screw 71, and a pulley assembly 74 is provided between the shaft of the motor 73 and the outer wall of the rotating tube 62.

[0043] When the refrigerant needs to be stirred, the motor 73 is controlled to work. At this time, with the cooperation of the pulley group 74, the rotating tube 62 is controlled to rotate, and with the cooperation of the spline 65, the rotating tube 62 drives the stirring rod 63 and the stirring blade 64 to move synchronously to achieve the stirring of the refrigerant.

[0044] At the same time, the motor 73 drives the reciprocating screw 71 to rotate, and the reciprocating screw 71 drives the connecting block 72 and the stirring rod 63 to reciprocate vertically, and can ensure that the stirring rod 63 and the stirring blade 64 reciprocate vertically while rotating stably, thereby achieving sufficient and uniform stirring of each layer of the refrigerant.

[0045] like Figure 3 、 Figure 4As shown, the stirring blade 64 includes a fixed seat 641, an upper rod 642, a lower rod 643 and a torsion spring 644. The fixed seat 641 is arranged below the stirring rod 63. The bottom wall of the collection barrel 1 is rotatably provided with a rotating table 13 for resisting the fixed seat 641 to prevent the fixed seat 641 from directly contacting the collection barrel 1 and causing wear.

[0046] like Figure 4 As shown, the upper end of the upper rod 642 is rotatably connected to the stirring rod 63, and the lower end of the lower rod 643 is rotatably connected to the fixed seat 641. The upper rod 642 and the lower rod 643 are rotatably connected, and the torsion spring 644 is arranged at the connection position between the upper rod 642 and the lower rod 643.

[0047] When the stirring blade 64 is working, the upper rod 642 and the lower rod 643 stir the material. When the stirring blade 64 moves downward, the fixed seat 641 contacts the rotating table 13, and as the stirring blade 64 continues to move downward, the connection position of the upper rod 642 and the lower rod 643 automatically rotates, thereby realizing the automatic expansion of the stirring blade 64.

[0048] When the stirring blade 64 moves upward, the torsion spring 644 can control the automatic rotation of the connection position of the upper rod 642 and the lower rod 643, thereby realizing the automatic retraction of the stirring blade 64, thereby disrupting the stirring law of the refrigerant during stirring, realizing sufficient stirring of the refrigerant, and ensuring the uniformity of the stirring effect.

[0049] like Figure 4 As shown, the outer walls of the upper rod 642 and the lower rod 643 are each provided with a stirring plate 645 to increase the contact area between the stirring blade 64 and the coolant, thereby achieving sufficient stirring of the coolant. A guide rod 646 is vertically provided on the fixed base 641 and is slidably connected to the stirring rod 63 to guide the movement of the fixed base 641 and increase the stability of the stirring blade 64 when it is freely extended and retracted.

[0050] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the embodiments as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
