Description

Technical Field

[0001] The present invention relates to the technical field of compressor diaphragm processing, and particularly relates to a processing device for a diaphragm of a diaphragm compressor. Background Art

[0002] A diaphragm compressor is a reciprocating compressor that compresses and transports gas by the reciprocating motion of a diaphragm in a cylinder. It does not produce any pollution during the compression process and is widely used in industries such as hydrogen energy. When producing the diaphragm in a diaphragm compressor, it is necessary to perform sandblasting treatment on the surface of the diaphragm. After the sandblasting treatment, the stress of the diaphragm is eliminated, the fatigue strength of the diaphragm is increased, and thus its service life is prolonged. The existing diaphragm sandblasting processing device usually uses manual operation to put the hand into the sandblasting box body and hold the sandblasting head by hand to perform sandblasting processing on the diaphragm. The uniformity of this sandblasting method is poor, resulting in uneven surface roughness of the processed diaphragm, affecting the effect of sandblasting treatment, and having a low processing efficiency. Moreover, after the sandblasting processing is completed, it is necessary to manually hold a blowing gun to clean the sand grains remaining on both sides of the diaphragm surface. The operation steps are cumbersome, resulting in a further reduction in the processing efficiency of the diaphragm. Therefore, a processing device for a diaphragm of a diaphragm compressor is needed to solve the above problems. Summary of the Invention

[0027] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] Please refer to Figure 1-10 , the present invention provides a technical solution:

[0029] A processing device for a diaphragm of a diaphragm compressor, including a box body 1, a mounting frame 3 and a lifting mechanism 4. The mounting frame 3 is connected to the inside of the box body 1. A support frame 2 is connected to the lower end of the box body 1. A transparent glass 13 for observing the processing situation is installed on the front side of the box body 1. A cabinet door 14 is connected to the side of the box body 1 through a hinge. A sand outlet 15 is provided at the bottom of the box body 1. The setting of the transparent glass 13 facilitates observing the sandblasting process of the diaphragm, and the setting of the sand outlet 15 facilitates discharging and replacing the sand grains.

[0030] The lifting mechanism 4 is installed on the mounting frame 3 and is used to drive the positioning frame 5 connected to its upper end to move up and down. The lifting mechanism 4 includes a lifting rod 41, a lifting frame 42 and a cylinder 43. There are 4 lifting rods 41 and they are distributed around the positioning frame 5. The lifting frame 42 is connected to the lower side of the positioning frame 5. A cylinder 43 for driving the lifting frame 42 to move up and down is installed on the mounting frame 3. An installation ring body 6 is rotatably connected to the middle of the positioning frame 5. The setting of the lifting mechanism 4 can drive the positioning frame 5 and the installation ring body 6 installed in the positioning frame 5 to move up and down, so as to realize the driving of the clamping assembly 10.

[0031] A turning-over assembly 7 for driving the installation ring body 6 to rotate is further arranged on the positioning frame 5. The turning-over assembly 7 includes a first motor 71 and a transmission belt 72. The first motor 71 is installed on the positioning frame 5. The installation ring body 6 is rotatably connected to the positioning frame 5 through a bushing 61. A pulley on the bushing 61 is connected to a pulley on the output end of the first motor 71 through the transmission belt 72. By arranging the turning-over assembly 7, the installation ring body 6 can be driven to drive the diaphragm to turn over, so as to facilitate automatic sandblasting processing on both sides of the diaphragm.

[0032] A supporting mechanism 8 for supporting the diaphragm is installed on the installation ring body 6. The supporting mechanism 8 includes a supporting frame 81, a first telescopic rod 82 and a first spring 83. The supporting frame 81 is slidably connected to the installation ring body 6 through the first telescopic rod 82. Four supporting frames 81 are provided and are arranged in pairs at the upper and lower ends inside the installation ring body 6. An annular block is arranged on the first telescopic rod 82. A first spring 83 for driving the supporting frame 81 to move closer to the installation ring body 6 is connected between the annular block and the inner wall of the installation ring body 6. Driving blocks 84 for driving the first telescopic rod 82 to slide are connected to both sides of the positioning frame 5. The supporting mechanism 8 can switch the position of the supporting frame 81 as the installation ring body 6 rotates, so that the supporting frame 81 located on the lower side of the installation ring body 6 is in an extended state, and the supporting frame 81 located on the upper side of the installation ring body 6 is in a contracted state. This setting method is convenient for loading the diaphragm and can ensure that the upper surface of the diaphragm is completely exposed, facilitating complete sandblasting treatment of the diaphragm.

[0033] A rotation driving assembly 9 for driving the diaphragm to rotate is further installed on the installation ring body 6. The rotation driving assembly 9 includes a rotating ring 91, a gear ring 92 and a second motor 93. The rotating ring 91 is rotatably connected to the middle position inside the installation ring body 6. The gear ring 92 is key-connected to the outer side surface of the rotating ring 91. A second motor 93 is installed on the installation ring body 6. A gear 94 meshing with the gear ring 92 is key-connected to the output end of the second motor 93. A sandblasting mechanism 11 for sandblasting the diaphragm is installed in the box body 1. The sandblasting mechanism 11 includes a connecting frame 111, an electric sliding table 112 and a driving frame 113. The electric sliding table 112 is installed above the installation ring body 6 through the connecting frame 111.

By arranging the rotation driving assembly 9, the diaphragm can be driven to rotate, and by cooperating with the linear motion of the sandblasting mechanism 11, rapid and uniform sandblasting treatment on the surface of the diaphragm can be realized.

[0034] A clamping assembly 10 for clamping and fixing the diaphragm is provided on the rotation driving assembly 9. The clamping assembly 10 includes a second telescopic rod 101, a clamping plate 102 and a roller 103. The clamping plate 102 is horizontally slidably connected to the rotating ring 91 through the second telescopic rod 101. Two clamping plates 102 are provided and symmetrically arranged on both sides of the rotating ring 91. One end of the second telescopic rod 101 is connected with a roller 103. A second spring 104 is connected between the roller 103 and the rotating ring 91. A push rod 106 is movably nested in the shaft sleeve 61. One end of the push rod 106 is connected with a push plate 105 for pushing the roller 103. Extrusion blocks 107 for pushing the push rod 106 are connected to both sides of the mounting frame 3. The clamping assembly 10 can cooperate with the lifting mechanism 4 to clamp and loosen the diaphragm, so as to facilitate the loading and unloading of the diaphragm.

[0035] The processing device further includes a dust removal assembly 12 for dust removal inside the box body 1. The dust removal assembly 12 includes a fan 121, a ventilation pipe 122 and a filter element 123. The air inlet of the fan 121 is connected to the top of the box body 1 through the ventilation pipe 122. The air outlet of the fan 121 is connected to the filter element 123 through the ventilation pipe 122. A dust collection box 124 is also connected to the ventilation pipe 122. The fan 121 extracts the air inside the box body 1. The processing powder with smaller mass is extracted together with the air and collected and filtered by the dust collection box 124 and the filter element 123. The setting of the dust removal assembly 12 facilitates the removal of the powder generated during the sandblasting process of the diaphragm, so as to ensure the cleanliness of the sand grains.

[0036] The working process of the present invention is as follows:

[0037] When sandblasting the compressor diaphragm is required, first place the diaphragm on the supporting bracket 81 below the mounting ring body 6. Start the cylinder 43 to drive the positioning frame 5 upward through the lifting frame 42. The positioning frame 5 drives the entire mounting ring body 6 to move upward synchronously. Since the extrusion block 107 is provided with an inclined surface in contact with the push rod 106, during the upward movement of the mounting ring body 6, the inclined surface on the extrusion block 107 extrudes the push rod 106. The push rod 106 is pressed to drive the push plate 105 connected to its other end to press the roller 103, so that the roller 103 drives the clamping plate 102 to clamp the diaphragm through the second telescopic rod 101. And the push plates 105 on both sides of the mounting ring body 6 can form a complete circular ring structure after approaching each other. The diaphragm can still be stably fixed when it rotates.

[0038] By starting the second motor 93 to drive the gear 94 to rotate, the gear 94 drives the rotating ring 91 to rotate through the gear ring 92, so that the clamping plate 102 drives the diaphragm to rotate synchronously; start the electric slide table 112 to drive the sandblasting head 114 to move horizontally in a uniform straight line above the diaphragm, and the sandblasting head 114 performs sandblasting on the surface of the diaphragm, realizing uniform sandblasting treatment on the surface of the diaphragm, and the sand grains remaining on the surface of the diaphragm are separated from the diaphragm under the action of the rotational centrifugal force of the diaphragm, without the need for cleaning after sandblasting is completed.

[0039] After sandblasting is completed on one end face of the diaphragm, start the first motor 71 to drive the mounting ring body 6 to rotate through the transmission belt 72, and the mounting ring body 6 rotates 180° to realize the turning operation of the diaphragm; during the rotation of the mounting ring body 6, since the driving block 84 is provided with an annular inclined surface, the supporting bracket 81 on the lower side of the mounting ring body 6 gradually moves towards the inner wall of the mounting ring body 6 under the action of the first spring 83, while the supporting bracket 81 on the upper side of the mounting ring body 6 moves away from the inner wall of the mounting ring body 6 under the extrusion of the driving block 84 and the first telescopic rod 82, realizing the switching of the position of the supporting bracket 81, ensuring that the upper surface of the diaphragm after turning is completely exposed, facilitating complete sandblasting treatment of the diaphragm; after sandblasting is completed, drive the positioning frame 5 to move downward through the cylinder 43, so that the clamping plate 102 releases the diaphragm, and the diaphragm can be taken off, thereby realizing automatic and complete sandblasting processing of the diaphragm.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
