Description
Technical Field
[0001] The utility model relates to the technical field of liquid accumulators, in particular to a liquid accumulator for storing refrigerant. Background Art
[0002] The refrigerant receiver is an important component in the refrigeration system. It stores excess refrigerant in the system for use when the system load changes. At the same time, the gas and liquid refrigerants can be separated inside the receiver. Since the liquid is heavier than the gas, it will settle at the bottom of the receiver, while the gas will remain at the top.
[0003] When using a liquid storage tank, the liquid refrigerant is continuously injected into the tank body. During the falling process, it will impact the liquid refrigerant stored inside, causing the liquid refrigerant to shake greatly inside the tank body, increasing the number and activity of the internal refrigerant molecules, increasing the impact force between molecules, and increasing the pressure inside the tank body, resulting in certain dangers when using the liquid storage tank. Utility Model Content
[0004] The purpose of the utility model is to solve the problem that when using a liquid receiver, the liquid refrigerant is continuously injected into the interior of the receiver body and will impact the liquid refrigerant stored inside during the falling process, causing the liquid refrigerant to shake greatly inside the receiver body, thereby increasing the number and activity of the internal refrigerant molecules, increasing the impact force between molecules, and increasing the pressure inside the tank body, resulting in certain dangers when using the liquid receiver. A liquid receiver for refrigerant storage is proposed to solve the problem that when using a liquid receiver, the liquid refrigerant is continuously injected into the interior of the receiver body and will impact the liquid refrigerant stored inside during the falling process, causing the liquid refrigerant to shake greatly inside the receiver body, thereby increasing the number and activity of the internal refrigerant molecules, increasing the impact force between molecules, and increasing the pressure inside the tank body, thereby causing certain dangers when using the liquid receiver.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a liquid storage device for storing refrigerant, including a tank body, an inlet pipe is provided at the top of the tank body, a liquid outlet pipe is fixedly connected to the top of the inner wall of the tank body, a valve body and a connecting pipe are provided at the top of the liquid outlet pipe, a buffer device is provided inside the tank body, and the buffer device includes a rotating shaft, one end of the rotating shaft is rotatably connected to one side of the inner wall of the tank body, a guide plate is fixedly connected to the outer surface of the rotating shaft, a guide groove is provided on the outer surface of the guide plate, a spring is provided at the bottom end of the guide plate, a floating plate is provided at the bottom end of the spring, and the upper and lower ends of the spring are fixedly connected to the bottom end of the guide plate and the top of the floating plate respectively.
[0006] The effect achieved by the above components is as follows: by setting the guide plate, the liquid refrigerant will be located at the bottom of the inner wall of the tank after entering the tank body. At this time, the float plate will float on the surface of the liquid refrigerant. When the liquid refrigerant enters the tank body through the inlet pipe, it will drip into the guide groove on the outer surface of the guide plate, and then flow into the tank body through the guide groove on the surface of the guide plate, slowing down the liquid refrigerant and reducing the impact force when the liquid refrigerant contacts the refrigerant at the bottom end of the inner wall of the tank body. At the same time, when the refrigerant level at the bottom end of the tank body rises, the float plate will also move up, and the spring will push the guide plate and the rotating shaft to rotate, so that the angle of the guide plate is deflected upward, and the angle between the guide plate and the liquid surface is expanded, slowing down the flow speed of the liquid refrigerant flowing down from the inlet pipe on the surface of the guide plate when the liquid refrigerant level inside the tank body is high, thereby improving the buffering effect.
[0007] Preferably, inclined grooves are provided on both sides of the bottom end of the floating plate, and balancing plates are fixedly connected to both sides of the bottom end of the floating plate.
[0008] The effect achieved by the above components is: when the liquid level at the bottom of the tank changes and causes the float plate to shake, the shaking on both sides of the float plate can be buffered by the inclined groove and the balance plate, thereby avoiding as much as possible the large shaking of the float plate that causes the guide plate position to continue to change.
[0009] Preferably, the top end of the floating plate is fixedly connected to a cylinder, the inner wall of the cylinder is slidably connected to a round rod, and the top end of the round rod is rotatably connected to the bottom end of the guide plate.
[0010] The effect achieved by the above components is: the floating plate moves up and down, causing the round rod to slide a certain distance on the inner wall of the cylinder. The cylinder and the round rod can limit the internal shape of the spring and the relative position between the floating plate and the guide plate, thereby improving the structural stability of the buffer device.
[0011] Preferably, a buffer block is fixedly connected to the inner wall of the guide groove, and the buffer block is made of silicone material.
[0012] The effect achieved by the above components is that liquid refrigerant is less likely to splash when it flows to the surface of the silicone buffer block on the inner wall of the guide groove, further improving the buffering effect of the buffer device on the refrigerant.
[0013] Preferably, a protective device is provided on the outer surface of the tank body, and the protective device includes a base, a plurality of mounting plates are fixedly connected to the outer surface of the base, and mounting holes are provided on the outer surface of the mounting plates. A positioning ring is fixedly connected to the top of the base, and a plurality of screws are threadedly connected to the inner wall of the positioning ring. One end of the screw is rotatably connected to a positioning block, and one end of the positioning block slides on the top of the positioning ring.
[0014] The effect achieved by the above components is: when installing the liquid reservoir, the tank body can be placed on the surface of the base in the positioning ring, and then the screws on the outer surface of the positioning ring are pushed to rotate, and the screws are controlled to move on the inner wall of the positioning ring to drive one end of the positioning block to slide on the outer surface of the positioning ring, and one side of each positioning block is respectively pressed against the outer surface of the tank body to fix the position of the tank body on the outer surface of the base, and the liquid reservoir is connected to the refrigeration equipment through the mounting block on the outer surface of the base, and the outer side of the tank body is protected by the base and the positioning ring to avoid damage to the tank body surface caused by direct collision in the event of an accident as much as possible.
[0015] Preferably, a pad is fixedly connected to one side of the positioning block, and the pad is made of rubber.
[0016] The effect achieved by the above components is that when the outer surface of the base is subjected to external force, the rubber pad between the positioning block and the tank body can further cushion the contact between the tank body and the positioning block, further reducing the probability of damage to the tank body.
[0017] Preferably, one end of the screw rod away from the positioning block is fixedly connected to an operating block, and a plurality of protrusions are provided on the outer surface of the operating block.
[0018] The effect achieved by the above components is that gripping the protrusions on the outer surface of the operating block can more conveniently control the rotation of the screw without slipping.
[0019] Preferably, auxiliary rods are fixedly connected to both sides of the base, and the cross-section of the auxiliary rods is U-shaped.
[0020] The effect achieved by the above components is that by holding the outer surface of the U-shaped auxiliary rod, the base can be lifted more conveniently to control the moving position of the base for disassembly and assembly.

[0032] Reference Figure 1 and Figure 4As shown, in this embodiment: one side of the positioning block 34 is fixedly connected to a pad 35, and the pad 35 is made of rubber material. When the outer surface of the base 31 is subjected to external force, the rubber pad 35 between the positioning block 34 and the tank body 1 can further cushion the contact between the tank body 1 and the positioning block 34, further reducing the probability of damage to the tank body 1.
