[0002] The discharge port of the two-in-one / three-in-one filter will be installed with a discharge device for controlling the opening and closing of the filter discharge. The existing device generally includes a cylinder that passes through from front to back, and the front end of the cylinder is connected to the discharge port of the filter. A plug that is driven by a hydraulic cylinder to move forward and backward is provided in the cylinder. When the plug plugs the front end of the cylinder, the filter discharge is in a closed state, and when the plug moves backward, the filter discharge is in an open state.

[0003] The filter needs to cooperate with the piston for discharging and sealing during use. However, the piston inside the existing filter is sometimes affected by the temperature and may not be sealed during use, resulting in leakage at the discharge pipe during the sealing process. In view of this, we provide a filter discharge device with a flange connection. Utility Model Content

[0021] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a flange-connected filter discharging device, comprising a body 1, a cover plate 8 is arranged on the body 1, materials can be put into the body 1 by opening the cover plate 8, a flange 2 is arranged on the side wall of the body 1, a filter discharge port 3 is arranged on the side of the flange 2, a support frame 4 is fixedly installed on the outer wall of the body 1, a hydraulic cylinder 5 is fixedly sleeved inside the support frame 4, a hydraulic rod 6 is arranged on the output end of the hydraulic cylinder 5, the hydraulic rod 6 can be driven to move toward the inside of the body 1 by starting the hydraulic cylinder 5, and a sealing mechanism 7 is arranged inside the body 1.

[0022] In this embodiment, a sealing mechanism 7 is provided inside the body 1. By squeezing the end of the support rod 79 through the hinged plate 710 in the sealing mechanism 7, the slider 74 can drive the squeezing plate 77 at the end of the connecting rod 76 to move toward the inner wall of the sealing plug 72. By squeezing the inner wall of the sealing plug 72 through the squeezing plate 77, the outer wall of the sealing plug 72 and the inner wall of the filter outlet 3 can be squeezed and fit tightly, making the interior of the filter outlet 3 more sealed. At the same time, by setting the protrusion 78 on the outer wall of the squeezing plate 77, the sealing plug 72 can be more easily squeezed and fit with the inner wall of the filter outlet 3 through the principle of small contact surface and large pressure, so that the sealing effect is optimized and leakage is prevented.

[0023] The above-mentioned sealing mechanism 7 includes a fixing frame 71, which is located inside the machine body 1. A sealing plug 72 is fixedly installed on the outer wall of the fixing frame 71. The sealing plug 72 is located at the side of the filter outlet 3. The solution inside the machine body 1 can be pushed to the inside of the filter outlet 3 to the left through the sealing plug 72, and then the material is filtered and discharged through the filter outlet 3. A fixing rod 73 is fixedly installed on the inner wall of the fixing frame 71, and a slider 74 is slidably connected to the outer wall of the fixing rod 73. A load-bearing spring 75 is sleeved on the outer wall of the fixing rod 73. One end of the load-bearing spring 75 is fixedly connected to the side wall of the slider 74, and the other end of the load-bearing spring 75 is fixedly connected to the inner wall of the fixing frame 71. The outer wall of the slider 74 is fixedly connected to one end of the connecting rod 76. An extrusion plate 77 is fixedly installed on the other end of the connecting rod 76. The extrusion plate 77 is set in an arc shape, and the connecting rod 7 is driven by the slider 74.

When the inside of the machine body 1 needs to be sealed after the discharge is completed, the hydraulic rod 6 is continued to drive the hinged plate 710 to move to the left, and then the end of the support rod 79 is squeezed by the hinged plate 710, and then the support rod 79 and the sliding The hinge between the blocks 74 causes the two sliders 74 to move back to back, and then the slider 74 drives the extrusion plate 77 at the end of the connecting rod 76 to move toward the inner wall of the sealing plug 72, so that the extrusion plate 77 squeezes the inner wall of the sealing plug 72. At the same time, the outer wall of the sealing plug 72 fits with the inner wall of the filter outlet port 3, so that the outer wall of the sealing plug 72 and the inner wall of the filter outlet port 3 are squeezed and tightly fit, making the interior of the filter outlet port 3 more sealed.
