Description

Technical Field

[0001] This utility model belongs to the technical field of cement unloading flap valves, and relates to a Y-type unloading flap valve structure for cement unloading. Background Technology

[0002] The main drawbacks of existing cement unloading flap valves in terms of unloading efficiency lie in their structure and working principle. The flap valve controls material flow by opening and closing a flapper plate, but this design often limits unloading speed due to the limited opening area and the time required for the flapper plate to move, which is particularly noticeable when handling large quantities of cement. Furthermore, the flap valve is prone to wear during frequent opening and closing, leading to decreased sealing performance and causing air and material leaks, thus affecting unloading efficiency. These shortcomings stem from the mechanical characteristics and limited flow area of ​​the flap valve. Conventional solutions include increasing the size of the flap valve to improve the flow area or optimizing the flapper plate's movement mechanism to reduce opening and closing time. However, these methods also have drawbacks. While increasing the size of the flap valve can improve unloading efficiency, it also increases equipment costs and installation space requirements, making it unsuitable for space-constrained applications. Optimizing the flapper plate's movement mechanism can reduce opening and closing time, but excessive mechanical optimization may lead to structural complexity, increased maintenance costs, and potential impacts on long-term operational reliability. Therefore, a Y-type unloading flap valve structure for cement unloading is urgently needed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a Y-type unloading flap valve structure for cement unloading, so as to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a Y-type unloading flap valve structure for cement unloading, comprising: an outer shell and an inner support beam, wherein the upper inner side of the outer shell is provided with a set of discharge chambers for guiding cement material, and the upper ends of the front and rear sides of the outer shell are respectively provided with two sets of positioning gears for controlling the left and right flipping and moving of the movable shell, and a set of movable shells for adjusting the cement unloading rate is provided in front of the positioning gears.

[0005] The front cross-section of the movable shell is a fan-shaped structure. Several sets of fixing bolts are provided between the upper end of the movable shell and the positioning gear. The fixing bolts are connected and fixed to the positioning gear. Each set of positioning gears corresponds to a set of movable shells. A set of connecting plates for maintaining the position of the positioning gears is provided on the front side of the internal shaft of the two sets of positioning gears.

[0006] As a preferred embodiment, the lower left side of the movable shell on the left side is provided with a set of fixing brackets for connecting and fixing with the telescopic head, and the lower right side of the movable shell on the right side is provided with a set of fixing brackets for connecting and fixing with the right side of the electric cylinder.

[0007] In a preferred embodiment, the inner sides of the fixed bracket 1 and fixed bracket 2 are provided with a set of electric cylinders for controlling the opening and closing of the two sets of movable shells and a telescopic head. The electric cylinders and the telescopic head are an integral structure. When the operator needs to control the unloading of the cement material inside, the front and rear sets of electric cylinders are activated simultaneously, and the electric cylinders push the telescopic head forward. While the telescopic head extends, it pushes the fixed bracket 1 and releases a reverse force to the fixed bracket 2. Simultaneously, the two sets of movable shells on the front and rear sides move outward respectively. The two sets of positioning gears can maintain the synchronous expansion angle of the two sets of movable shells, thereby controlling the unloading efficiency of the cement material.

[0008] In a preferred embodiment, a set of support frames for synchronous movement connection is provided between the left and right sides of the two sets of movable shells on the left and right sides, and a set of inner lining plates for retaining cement material is provided between the lower ends of the two sets of movable shells on the left and right sides.

[0009] In a preferred embodiment, the inner lining plate is provided in two sets, and the lower end of each set of the inner lining plate is provided with several sets of external reinforcing trusses for improving the support strength of the inner lining plate. Each set of the movable shell is provided with a set of internal support beams for improving the support strength of the movable shell.

[0010] In a preferred embodiment, each set of inner support beams is fixed to the inner side of a set of movable shells by bolts. The front cross-section of the inner support beam is a triangular structure. Due to the high viscosity and weight of the cement material, when the cement material inside the shell is fully loaded, the inner support beam, the outer reinforcing truss, and the inner support beam can effectively improve the load strength of the cement material, thereby ensuring the stability of the structure.

[0011] In a preferred embodiment, the upper end of the inner liner is provided with a set of embedded edges on the front and rear sides for sealing and fitting with the lower end of the outer shell. The embedded edges are movably and sealingly fitted with the lower end of the outer shell.

[0012] In a preferred embodiment, the two sets of movable shells, support frames, and inner lining plates on the left side constitute a set of left-side flap valve bodies, and the two sets of movable shells, support frames, and inner lining plates on the right side constitute a set of right-side flap valve bodies.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the staff needs to control the unloading of the cement material inside, the front and rear electric cylinders are activated simultaneously, and the electric cylinders push the telescopic head forward. While the telescopic head extends, it pushes the first fixed bracket and releases a reverse force to the second fixed bracket. At the same time, the two sets of movable shells on the front and rear sides move outwards. The two sets of positioning gears can keep the two sets of movable shells expanding at the same angle, thereby controlling the unloading efficiency of the cement material. Since the cement material is highly viscous and heavy, when the cement material inside the shell is fully loaded, the inner support beam, the outer reinforcing truss, and the inner support beam can effectively improve the load strength of the cement material, thereby ensuring the stability of the structure.
