Description

Technical Field

[0001] The utility model relates to the technical field of discharge valves, in particular to a discharge valve with a supporting and limiting function. Background Art

[0002] The discharge valve, also known as the discharger, is the main equipment for dust removal equipment to discharge dust, supply air and feed other equipment. It is suitable for powdery and granular materials and plays the function of transferring and transporting materials. With the continuous use of the discharge valve, the traditional discharge valve is equipped with a drive motor on the side. Since the drive motor of the discharge valve is heavy and far away from the center of the valve body, the discharge valve is easy to tilt under the action of gravity, causing deformation of the connection and causing material leakage.

[0003] According to the description of a discharge valve with a support and limit function disclosed on the patent website (authorization announcement number: CN210164972U), "The utility model discloses a discharge valve with a support and limit function, including a discharge valve body, a second bearing and a limit plate, a side threaded column is fixed to the bottom end side of the discharge valve body, a first through nut is installed on the mounting plate, and the first through nut is interconnected with the first adjusting bolt, and the top of the first adjusting bolt is interconnected with the inner side of the first bearing, the outer side of the first bearing is fixed to the bottom end of the support plate, and the support plate is interconnected with the discharge valve body, a second through nut is installed on the mounting plate, and the second through nut is interconnected with the second adjusting bolt. The discharge valve with a support and limit function adopts a new structural design, so that after the device is connected to the external structure, the part extending away from the center of the device can be supported and fixed, so as to avoid deformation of the connection between the device and the external structure due to gravity, which causes leakage and difficulty in disassembly and maintenance."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, since the device rotates inside the first through nut through the first adjusting bolt, the support plate is driven to rise and fall to support the motor part of the discharge valve body, but the support plate is not limited. This will cause the support plate to rotate when the first adjusting bolt is twisted. Therefore, the support plate needs to be adjusted before it approaches the discharge valve body, which is inconvenient to use. Therefore, it is necessary to improve a discharge valve with a support limit function to solve the above problem. Utility Model Content
