Description

Technical Field

[0001] This utility model relates to the field of air filtration device technology, and in particular to an anti-clogging air filtration device for air conditioning refrigeration systems. Background Technology

[0002] The main task of anti-clogging air filters is to prevent dust, dirt, and other impurities from passing through the air conditioning system while ensuring smooth airflow. In air conditioning refrigeration systems, the air filter used for anti-clogging is usually a dryer filter. The dryer filter is a key component of the air conditioning refrigeration system. It uses an internal desiccant (such as molecular sieves, activated alumina, etc.) to adsorb moisture in the refrigerant, preventing moisture from freezing at low temperatures and causing ice blockage. At the same time, it uses materials such as metal filter screens or polyester filter screens to filter solid impurities in the refrigerant, preventing impurities from clogging throttling elements (such as expansion valves and capillary tubes) or damaging the compressor.

[0003] Patent document CN205164354U discloses an anti-clogging air filtration device. This utility model discloses an anti-clogging air filtration device, including a body and a cover, which together form a sealed space. A dust filter cup and a spring are arranged within the sealed space. The dust filter cup is pressed against a step within the body by the spring. The dust filter cup divides the sealed space into left and right chambers. An inlet and an outlet are respectively provided on the body, communicating with the left and right chambers. In normal operation, compressed air entering through the inlet is filtered by the dust filter cup and output through the outlet. In a blocked state, compressed air entering through the inlet passes through the annular gap between the dust filter cup and the inner wall of the body and outputs through the outlet. This utility model utilizes the cooperation of the spring and the dust filter cup. The dust filter cup filters compressed air, and when the dust filter cup is blocked, the compressed air overcomes the pressure of the spring, pushing the dust filter cup open, allowing the compressed air to pass through the annular gap between the dust filter cup and the inner wall of the body and output through the outlet, thereby preventing blockage of the passage.

[0004] However, existing air conditioning refrigeration systems with anti-clogging air filters are difficult to open conveniently to replace the internal desiccant or clean the internal structure, making the operation process complicated and reducing maintenance efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging air filter device for an air conditioning refrigeration system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging air filter device for an air conditioning refrigeration system, comprising a cylindrical body, a collar fixedly connected to one end of the cylindrical body, an upper clamping ring snapped onto the surface of the collar, a lower clamping ring rotatably connected to one end of the upper clamping ring, and a fixing block fixedly connected to one end of both the upper and lower clamping rings. Two sets of limiting components are slidably connected to the top of one set of the fixing blocks. A positioning ring is snapped onto the inner wall of one end of the cylindrical body, and a sealing component is snapped onto one side of the positioning ring. The limiting component includes a rod slidably connected to the top of the fixing block, a limiting ring sleeved on the surface of the rod, and a support spring fixedly connected to the bottom of the limiting ring. The sealing component includes a movable ring snapped onto one side of the positioning ring, and several sets of positioning springs are fixedly connected in a circular array on one side of the movable ring.

[0007] As a further embodiment of this utility model, a groove is provided on one side of each of the two sets of fixing blocks, and a rotating rod is rotatably connected to the inner wall of one set of the grooves, with a fixing bolt sleeved on the surface of the rotating rod.

[0008] As a further embodiment of this utility model, a semi-circular limiting rod is sleeved on the top of the fixing bolt, and a slot that matches the semi-circular limiting rod is fixedly connected to the top of the insertion rod.

[0009] As a further embodiment of this utility model, one end of the positioning spring is fixedly connected to a support ring, and an end cap is sleeved on the surface of the support ring.

[0010] As a further embodiment of this utility model, one side of the end cap is snapped into the interior of the lower clamping ring, and one end of the end cap is fixedly connected to a connecting joint.

[0011] As a further embodiment of this utility model, a filter screen is snapped into the inside of the cylinder, and a desiccant is provided inside the cylinder.

[0012] As a further embodiment of this utility model, one end of the cylinder is fixedly connected to a connecting pipe, one end of the connecting pipe is connected to a connecting pipe, and one end of the connecting pipe is connected to an installation joint.

[0013] As a further embodiment of this utility model, the fixed block has a sliding hole inside that matches the insertion rod, and the movable ring has a slot on one side that matches the positioning ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The anti-clogging air filter device used in this air conditioning refrigeration system, through the setting of an upper clamping ring, a lower clamping ring, and a limiting component, allows for easy opening of the filter device when the two sets of insert rods are pressed. This causes the insert rods to drive the limiting rings to compress the support springs, resulting in the support springs contracting under force. Consequently, the top slot of the insert rod disengages from the surface of the semi-circular limiting rod, pulling the fixing bolt. The rotating rod rotates within the fixing block, further pulling the upper and lower clamping rings, causing them to disengage from the collar and end cap surfaces, thus opening the filter device. This achieves the effect of conveniently opening the air filter device, facilitating the replacement of the internal desiccant or cleaning of the internal structure, and simplifying desiccant replacement and... The internal cleaning process improves maintenance efficiency. The air conditioning refrigeration system uses an anti-clogging air filter device. Through the setting of the sealing components, during installation, since one end of the cylinder and one side of the end cover are fixed, the positioning ring is fixed inside one end of the cylinder. Then, the movable ring is inserted into one side of the positioning ring, causing the movable ring to compress the positioning spring. Since the position of the support ring remains unchanged, the positioning spring generates elastic force to push the movable ring in the opposite direction to restore its deformation. This keeps the movable ring tightly against the positioning ring, thereby achieving a dynamic sealing effect at the joint. This compensates for the assembly tolerance between the cylinder and the end cover and the material deformation after long-term use, ensuring that the joint always maintains an effective seal.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: an anti-clogging air filter device for an air conditioning refrigeration system, comprising a cylinder 1, a collar 2 fixedly connected to one end of the cylinder 1, an upper clamping ring 3 snapped onto the surface of the collar 2, a lower clamping ring 4 rotatably connected to one end of the upper clamping ring 3, and a fixing block 5 fixedly connected to one end of both the upper clamping ring 3 and the lower clamping ring 4. Two sets of limiting components 6 are slidably connected to the top of one set of fixing blocks 5. Through the arrangement of the upper clamping ring 3, the lower clamping ring 4, and the limiting components 6, the air filter device can be easily opened, facilitating the replacement of the internal desiccant 16 or the cleaning of the internal structure. This simplifies the operation process of replacing the desiccant 16 and cleaning the internal structure, improving maintenance efficiency. A positioning ring 7 is snapped onto the inner wall of one end of the cylinder 1, and a sealing component 8 is snapped onto one side of the positioning ring 7. The sealing component 8 achieves a dynamic sealing effect at the joint, compensating for the assembly tolerance between the cylinder 1 and the end cap 13 and the material deformation after long-term use, ensuring that the joint remains effectively sealed. The limiting component 6 includes a rod 601 slidably connected to the top of the fixed block 5. A limiting ring 602 is sleeved on the surface of the rod 601, and a support spring 603 is fixedly connected to the bottom of the limiting ring 602. The sealing component 8 includes a movable ring 801 snapped onto one side of the positioning ring 7, and several sets of positioning springs 802 are fixedly connected in a ring array on one side of the movable ring 801.

[0024] One side of each of the two sets of fixing blocks 5 has a groove. The inner wall of one set of grooves is rotatably connected to a rotating rod 9. A fixing bolt 10 is sleeved on the surface of the rotating rod 9. The fixing bolt 10 facilitates the rotation of the rotating rod 9.

[0025] The top of the fixing bolt 10 is fitted with a semi-circular limiting rod 11, and the top of the insertion rod 601 is fixedly connected with a slot that matches the semi-circular limiting rod 11. The slot facilitates the semi-circular limiting rod 11 to be inserted and limited.

[0026] One end of the positioning spring 802 is fixedly connected to a support ring 12, and an end cap 13 is sleeved on the surface of the support ring 12. The end cap 13 serves to close the cylinder 1.

[0027] One side of the end cap 13 is snapped into the inside of the lower clamping ring 4, and one end of the end cap 13 is fixedly connected to a connecting connector 14. The connecting connector 14 serves to connect to external equipment.

[0028] A filter screen 15 is snapped into the inside of the cylinder 1, and a desiccant 16 is installed inside the cylinder 1. The desiccant 16 dries the air.

[0029] One end of the cylinder 1 is fixedly connected to a pipe 17, one end of the pipe 17 is connected to a connecting pipe 18, and one end of the connecting pipe 18 is connected to an installation connector 19. The installation connector 19 facilitates installation and connection.

[0030] The fixed block 5 has a sliding hole inside that matches the insertion rod 601, and the movable ring 801 has a slot on one side that matches the positioning ring 7. The slot facilitates a tight connection between the movable ring 801 and the positioning ring 7.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When the filter needs to be opened, press the two sets of insert rods 601, so that the insert rods 601 drive the limiting rings 602 to squeeze the support springs 603, so that the support springs 603 are compressed by force, and then the top slot of the insert rods 601 disengages from the surface of the semi-circular limiting rods 11, pulls the fixing bolts 10, and rotates the rods 9 within the fixing block 5, thereby pulling the upper clamping rings 3 and the lower clamping rings 4, disengaging them from the surface of the collar 2 and the end cap 13, and thus opening the filter;

[0033] Second step: During installation, since one end of the cylinder 1 and one side of the end cap 13 are fixedly installed, the positioning ring 7 is fixed inside one end of the cylinder 1. Then, the movable ring 801 is inserted into one side of the positioning ring 7, so that the movable ring 801 compresses the positioning spring 802. Since the position of the support ring 12 remains unchanged, the positioning spring 802 generates elastic force to push the movable ring 801 in the opposite direction to restore its deformation, so that the movable ring 801 is always tightly attached to the positioning ring 7.
