Description

Technical Field

[0001] The utility model relates to the technical field of screw compressors, in particular to an exhaust end seat of a screw compressor. Background Art

[0002] Screw compressors include screw air compressors and screw process compressors. Screw compressors are positive displacement twin-screw oil-injected compressors, generally box-type skid-mounted structures, with suction and exhaust ports arranged diagonally at both ends of the body. As the rotor rotates in the body, the working volume changes continuously due to the intrusion or disengagement of the teeth, thereby periodically changing the volume between each pair of rotor teeth to achieve the purpose of suction, compression and exhaust.

[0003] The exhaust end seat of the twin-screw compressor in the prior art is not easy to disassemble and assemble. Generally, multiple bolts need to be removed during disassembly, and the steps are complicated and inconvenient to disassemble and assemble, which makes it more troublesome to repair the compressor and has low practicality. Utility Model Content

[0004] The utility model aims to provide an exhaust end seat of a screw compressor to solve the technical problem that it is inconvenient to disassemble the exhaust end seat of the screw compressor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an exhaust end seat of a screw compressor, comprising a casing, an extrusion plate and an end seat, a movable ring being threadedly connected to the casing, a connecting groove being provided inside the movable ring, a plurality of extrusion plates being fixedly connected to one side with a connecting rod, a plurality of limit rods arranged in an annular array being fixedly connected to the casing, a plurality of extrusion plates being provided with limit grooves at positions corresponding to the limit rods, a plurality of mounting seats arranged in an annular array being fixedly connected to the casing, a plurality of mounting seats being rotatably connected to support rods, a plurality of support rods being fixedly connected to pressure-bearing rods, a plurality of pressure-bearing seats arranged in an annular array being fixedly connected to the end seat, and a plurality of pressure-bearing rods being fixedly connected to extrusion seats at positions corresponding to the pressure-bearing seats.

[0006] As a preferred solution of the utility model, four limiting rods and four extrusion plates are provided, and the limiting rods are slidably connected to the inside of the limiting grooves.

[0007] As a preferred solution of the utility model, a lever ring is fixedly connected to one side of the moving ring, and a plurality of lever grooves arranged in a circular array are provided on the lever ring.

[0008] As a preferred solution of the utility model, the end seat is slidably connected to one side of the casing, and one side of the connecting rod is slidably connected to the inside of the connecting groove.

[0009] As a preferred solution of the utility model, four extrusion seats and four pressure-bearing seats are provided, and the relative walls of the pressure-bearing seats and the extrusion seats are in contact with each other.

[0010] Compared with the prior art, the beneficial effect of the exhaust end seat of the screw compressor of the utility model is that when disassembling the end seat, it is only necessary to rotate the moving ring to move the moving ring, and the movement of the moving ring affects various mechanisms. At this time, the extrusion seat no longer applies pressure to the pressure-bearing seat to fix it, and the end seat can be removed from one side of the casing. The disassembly is convenient and the disassembly efficiency is extremely high, thereby facilitating the inspection and maintenance of the interior of the casing and improving the overall practicality.

For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0020] See also Figure 1-4 As shown, an exhaust end seat of a screw compressor in an embodiment of the utility model includes a casing 1, an extrusion plate 2 and an end seat 3. A movable ring 4 is threadedly connected to the casing 1, a connecting groove 5 is provided inside the movable ring 4, a plurality of extrusion plates 2 are fixedly connected to one side with a connecting rod 6, a plurality of limit rods 7 arranged in a ring array are fixedly connected to the casing 1, and a plurality of extrusion plates 2 are provided with limit grooves 8 at the positions corresponding to the limit rods 7.

[0021] The casing 1 is fixedly connected to a plurality of mounting seats 9 arranged in a circular array, the plurality of mounting seats 9 are rotatably connected to support rods 10, the plurality of support rods 10 are fixedly connected to pressure rods 11, the end seat 3 is fixedly connected to a plurality of pressure seats 12 arranged in a circular array, and the plurality of pressure rods 11 are fixedly connected to extrusion seats 13 at positions corresponding to the pressure seats 12.

[0022] There are four limit rods 7 and four extrusion plates 2 , and the limit rods 7 are slidably connected to the inside of the limit grooves 8 . The connection between the limit rods 7 and the limit grooves 8 facilitates the movement guidance of the extrusion plate 2 .

[0023] See also Figure 3 As shown, a lever ring 14 is fixedly connected to one side of the movable ring 4. The lever ring 14 is provided with a plurality of lever grooves 15 arranged in a circular array. The staff can insert external tools into the lever grooves 15 to facilitate the rotation of the lever ring 14 and the movable ring 4.

[0024] The end seat 3 is slidably connected to one side of the housing 1 , and one side of the connecting rod 6 is slidably connected to the inside of the connecting groove 5 .

[0025] There are four extrusion seats 13 and four pressure-bearing seats 12 , and the opposite walls of the pressure-bearing seats 12 and the extrusion seats 13 abut against each other.

[0026] When using the embodiment of the utility model, a tool is inserted into the lever groove 15, and the lever ring 14 is rotated through the connection between the tool and the lever groove 15. The rotation of the lever ring 14 will drive the movable ring 4 to rotate together, and the movable ring 4 will move in the opposite direction of the end seat 3 when it rotates. The movement of the movable ring 4 will pull the connecting rod 6 through the connecting groove 5, and the pulling of the connecting rod 6 will drive the extrusion plate 2 to move. Multiple extrusion plates 2 all move under the guidance of the limit rod 7. At this time, the extrusion plate 2 no longer squeezes the pressure-bearing rod 11, and the pressure-bearing rod 11 and the extrusion seat 13 cannot apply high-intensity pressure to the pressure-bearing seat 12. At this time, the staff can rotate the pressure-bearing rod 11 through the support rod 10, so that the extrusion seat 13 and the pressure-bearing seat 12 are no longer abutted, and then the end seat 3 can be removed.

[0027] During installation, the operating steps are similar. The end seat 3 can be connected to the casing 1, and then the moving ring 4 drives the connecting rod 6 and the extrusion plate 2 to move toward the end seat 3. The moving extrusion plate 2 will squeeze the pressure rod 11, and the pressure rod 11 will be squeezed and drive the extrusion seat 13 to rotate toward the pressure seat 12 on the end seat 3. At this time, the extrusion seat 13 and the pressure seat 12 are abutted again. At this time, the moving ring 4 is rotated vigorously, and the extrusion plate 2 will apply a huge extrusion force to the pressure rod 11, and the pressure rod 11 will make the extrusion seat 13 tightly buckle the pressure seat 12. At this time, the connection of the end seat 3 is completed.

[0028] The above shows and describes the basic principles of the present invention.
