Description

Technical Field

[0001] This invention relates to the technical field of unloading valves, and in particular to a silo unloading gate valve. Background Technology

[0002] A silo is a container used in industrial production, logistics storage, and agricultural processing to centrally contain, temporarily store, or transfer materials.

[0003] The dewatering silo (also called a dewatering bin) is equipped with a discharge gate valve at the bottom for solid-liquid separation and discharge. This discharge valve consists of four parts: a valve body, a valve plate, a valve stem, and a wheel. Its specific structure and functional logic are as follows: The valve body, as the fixed base of the device, is rigidly connected to the bottom of the dewatering bin, forming a material discharge channel frame; the valve plate is a movable actuator, fitted into the inner cavity of the valve body and sealed to it. Its surface has filter holes to filter residual dewatering water from the material, preventing water entrainment during discharge; the valve stem is installed on the valve body, its installation direction matching the valve plate's movement, with one end connected to the valve plate and the other end fixedly connected to the wheel; the wheel is the operating component, which can be manually rotated or mechanically driven to synchronously move the valve stem, thereby controlling the opening and closing degree of the valve plate, controlling the discharge rate, and ultimately allowing the dewatered material to be discharged along the valve body channel. The discharge valve of this type of dewatering silo has both the drain port and the discharge port located in the same place, which causes the drain and discharge to flow out from the same place. This requires a diversion device to be installed below the dewatering silo. At the same time, the valve plate is hidden inside the valve body, making it difficult to clean the filter holes and affecting the discharge efficiency.

[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems: The existing silo discharge gate valve cannot separate solid and liquid flows, and the valve plate is difficult to clean, which affects the discharge efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a silo unloading gate valve that solves the technical problems of existing dewatering silo unloading gate valves, which cannot perform solid-liquid separation and have difficult valve plate cleaning, thus affecting unloading efficiency.

[0006] Invention solution: This invention provides a hopper unloading gate valve, comprising a gate body, a gate panel, a cylinder rod, and a hydraulic cylinder; the gate body includes a frame, a flange plate, an unloading plate, a slide rail, a first working area, and a second working area; the flange plate is fixedly installed above the frame, the unloading plate is installed below the frame, the slide rail is fixedly installed on the unloading plate, the first working area is located between the flange plate and the unloading plate, and the second working area is located on one side of the first working area; the gate panel is slidably connected to the slide rail and is provided with a filter element, a water receiving groove, and a water flow hole; the filter element is installed on the gate panel, the water receiving groove is located below the filter element, and the water flow hole communicates with the water receiving groove; the frame is provided with a water flow pipe, the position of which corresponds to the position of the water flow hole; one end of the cylinder rod is fixedly connected to the gate panel, and the other end is fixedly connected to the output end of the hydraulic cylinder, the hydraulic cylinder being installed on the frame.

[0007] Furthermore, the filter element includes a filter frame and a filter screen; the door panel is provided with a insertion slot, the filter frame is installed in the insertion slot, and the filter screen is installed in the filter frame.

[0008] Furthermore, the door panel is provided with a sliding groove, and a slider is provided in the sliding groove, the slider being adapted to the sliding rail.

[0009] Furthermore, the door panel is provided with a water flow seat, the water flow seat is provided with an elastic washer, and the position of the water flow seat corresponds to the water flow hole and the water flow pipe respectively.

[0010] Furthermore, a sealing ring is provided at the bottom of the flange plate, which can abut against the door panel.

[0011] Furthermore, the flange plate is connected to a support plate, the support plate is connected to an upper cleaning pipe, and the upper cleaning pipe is connected to a plurality of upper cleaning nozzles.

[0012] Furthermore, the flange plate is equipped with a connecting seat, the connecting seat is equipped with a bolt, the bolt is threaded with a height adjusting nut, and a scraper is connected to the bottom of the bolt; the door panel is provided with a scraper groove, and the scraper is adapted to the scraper groove.

[0013] Furthermore, the unloading plate is provided with a lower cleaning pipe, and the lower cleaning pipe is connected to a plurality of lower cleaning nozzles.

[0014] Furthermore, the unloading plate is connected to a baffle plate, and the baffle plate is provided with a seat opening.

[0015] Furthermore, the frame is connected to a water collection device and a protective cover, with the water collection device located below the second working area and the protective cover located above the second working area.

[0016] Beneficial Effects: The silo discharge gate valve provided by this invention, when closed, has the gate plate and filter element located in the first working area. Material from the dewatering silo falls onto the filter element, and the moisture from the material flows through the filter element into the water receiving tank, then into the water outlet, and finally into the water pipe, flowing out from the side of the frame. When open, the hydraulic cylinder drives the cylinder rod to move, which in turn moves the gate plate and filter element into the second working area. At this time, the dewatered material flows out from the discharge plate, also flowing out from below the frame, achieving solid-liquid separation. This eliminates the need for a flow diversion device below the dewatering silo. The gate plate and filter element are exposed in the second working area, facilitating cleaning. Therefore, this silo discharge gate valve can achieve solid-liquid separation, and the gate plate and filter element are easy to clean without affecting the discharge efficiency.
