[0020] The present utility model provides an air intake adjustment device for the underflow port of a hydrocyclone, which includes a hydrocyclone body 100 and an adjustment assembly. The adjustment assembly includes a mounting ring 101, an elastic hose 102, a fixing member, a lead-out pipe 103, an adjustment block 104, a driving member, and a moving ring 105. The fixing member includes a connecting block 106, a fixing rod 107, and a fixing element. The fixing element includes a fixing block 108 and a fixing ring 109. The driving member includes a mounting base 110, a hydraulic rod 111, and a guiding element. The guiding element includes a fixing base 112 and a guiding rod 113. By this solution, the problem that a hydrocyclone generally needs to replace underflow ports with different specifications and sizes to meet different working requirements of the hydrocyclone is solved. In this way, not only is it necessary to equip multiple specifications of underflow ports, increasing production costs, but also the equipment needs to be paused when replacing the underflow port, which is not conducive to improving production and processing efficiency.

[0021] For this specific embodiment, the hydrocyclone body 100 is the hydrocyclone described in the existing patent technology CN200945461Y flat-bottom hydrocyclone. Through the hydrocyclone body 100, the accumulation of coarse and heavy materials in the cylinder is eliminated, the overflow of coarse particles and the entrainment of fine particles in the underflow (sand) are reduced, and the classification efficiency and classification accuracy can be improved. By this solution, it is realized that the inner diameter of the underflow port can be changed online without stopping production during the working process of the hydrocyclone, and the operation is simple and the impact on production is minimized to the greatest extent.

[0022] Among them, the mounting ring 101 is fixedly connected to the cyclone body 100 and is located below the cyclone body 100. The elastic hose 102 is fixedly connected to the mounting ring 101 and is located on the side of the mounting ring 101 away from the cyclone body 100. The outlet pipe 103 is fixedly connected to the elastic hose 102 and is located at one end of the elastic hose 102 away from the mounting ring 101. The fixing member is installed on the mounting ring 101, and the fixing member supports the outlet pipe 103.

The moving ring 105 is connected to the mounting ring 101 through the driving member, and the driving member drives the moving ring 105 to move. The moving ring 105 abuts against the adjusting block 104. The mounting ring 101 is installed on the cyclone body 100 by bolts. The elastic hose 102 is fixedly installed on the inner side of the mounting ring 101 by a buckle, so that the raw material in the cyclone body 100 flows into the elastic hose 102 from the mounting ring 101. The outlet pipe 103 is installed on one end of the elastic hose 102 away from the mounting ring 101 by a buckle, and the outlet pipe 103 is fixed by the fixing member to prevent the outlet rod from shaking. The adjusting block 104 is installed on the outer side of the elastic hose 102 by bolts. By squeezing the adjusting block 104, the inner diameter of the underflow port is changed. The moving ring 105 is installed on the outer side of the elastic hose 102 through the driving member. By driving the moving ring 105 to move through the driving member, the moving ring 105 abuts against the adjusting block 104. Due to the design of the inclined surface of the adjusting block 104, the elastic hose 102 is contracted and squeezed inward, thereby changing the inner diameter of the elastic hose 102. Thus, it is realized that the inner diameter of the underflow port can be changed online without stopping production during the working process of the cyclone, the operation is simple and the influence on production is minimized to the greatest extent.

[0023] Secondly, the connecting block 106 is fixedly connected to the mounting ring 101 and is located on the side of the mounting ring 101 away from the cyclone body 100; the fixing rod 107 is fixedly connected to the connecting block 106 and is located on the side of the connecting block 106 away from the mounting ring 101; the fixing rod 107 is connected to the outlet pipe 103 through the fixing element, and the fixing element supports the outlet pipe 103. The connecting block 106 is mounted on the side surface of the mounting ring 101 by bolts, and the fixing rod 107 is mounted on the side of the connecting block 106 away from the mounting ring 101 by bolts. Through the connecting block 106, the fixing rod 107 is stably mounted on the mounting ring 101, and the outlet pipe 103 is mounted on the fixing rod 107 through the fixing element, enabling the fixing rod 107 to stably support the outlet pipe 103.

[0024] Meanwhile, the fixing block 108 is fixedly connected to the fixing rod 107 and is located at one end of the fixing rod 107 away from the connecting block 106; the fixing ring 109 is fixedly connected to the fixing block 108 and is located on the side of the fixing block 108 away from the fixing rod 107 and is connected to the outlet pipe 103. The fixing block 108 is mounted on the end of the fixing rod 107 away from the connecting block 106 by bolts, the fixing ring 109 is mounted on the side of the fixing block 108 away from the connecting block 106 by bolts, and the outlet pipe 103 is mounted on the inner side of the fixing ring 109 by bolts. Through the cooperation of the fixing ring 109 and the fixing ring 109, the outlet pipe 103 is stably mounted on the fixing rod 107.

[0025] In addition, the mounting base 110 is fixedly connected to the mounting ring 101 and is located on the side of the mounting ring 101 away from the connecting block 106; the hydraulic rod 111 is fixedly connected to the mounting base 110 and is located on the side of the mounting base 110 away from the mounting ring 101 and is connected to the moving ring 105; the guiding element is mounted on the mounting ring 101, and the guiding element supports the moving ring 105. The mounting base 110 is mounted on the side of the mounting ring 101 away from the cyclone body 100 by bolts, the hydraulic rod 111 is mounted on the side of the mounting base 110 away from the mounting ring 101 by bolts, and the output end of the hydraulic rod 111 is connected to the moving ring 105 by bolts. By driving the moving ring 105 to move through the hydraulic rod 111, the contraction size of the elastic hose 102 is controlled. The guiding element is mounted on the mounting ring 101, and the moving trajectory of the moving ring 105 is restricted through the guiding element, avoiding the phenomenon that the moving ring 105 drives the hydraulic rod 111 to tilt.

[0026] Finally, the fixed base 112 is fixedly connected to the mounting ring 101 and is located on one side of the mounting ring 101 close to the mounting base 110; the guide rod 113 is fixedly connected to the mounting base 110, is located on one side of the fixed base 112 away from the mounting ring 101, and is connected to the moving ring 105. The fixed base 112 is mounted on one side of the mounting ring 101 close to the mounting base 110 by bolts. The guide rod 113 is mounted on the fixed base 112 by bolts, and the guide rod 113 passes through the moving ring 105. The moving trajectory of the moving ring 105 is restricted by the guide rod 113, so as to ensure that the moving ring 105 can stably press the adjusting block 104, thereby changing the inner diameter of the elastic hose 102.

[0027] When using the inlet air adjustment device at the underflow port of the cyclone in this embodiment, when it is necessary to adjust the inner diameter of the inlet air at the underflow port, start the hydraulic rod 111. The hydraulic rod 111 drives the moving ring 105 to move, so that the moving ring 105 abuts against the adjusting block 104. By moving the moving ring 105, the adjusting block 104 moves downward. Since the thickness of the adjusting block 104 is inconsistent, the moving ring 105 controls the descending distance of the adjusting block 104 by the moving distance, thereby controlling the contraction size of the elastic hose 102. Thus, it is realized that the inner diameter of the underflow port can be changed online without stopping production during the working process of the cyclone, and the operation is simple and the impact on production is minimized.
