Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and more specifically, to an adjustable ash discharge valve device for a feed pipe. Background Technology

[0002] Raw materials such as limestone, clay, and iron ore, which are mined, are usually in large chunks. They must first be crushed into smaller particles by crushers (such as jaw crushers and cone crushers) to facilitate further processing and uniform mixing. For example, raw limestone ore may first undergo coarse crushing with a jaw crusher, and then fine crushing with a cone crusher to achieve a certain particle size, generally between a few millimeters and tens of millimeters.

[0003] Cement production crushing and processing equipment discharges material through a feed pipe. Existing feed pipes use built-in valve plates for opening and closing, resulting in poor operability. Furthermore, the locking mechanism makes it inconvenient to adjust the discharge power according to the ash discharge volume, further complicating operability. Therefore, we propose an adjustable ash discharge valve device for the feed pipe. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an adjustable ash discharge valve device for the discharge pipe, so as to solve the technical problems of the current discharge mechanism having inconvenient discharge volume adjustment and poor operability.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable ash discharge valve device for a feeding pipe, comprising an adjusting mechanism, a baffle, a handle, and a locking mechanism. The baffle is rotatably installed inside the feeding pipe. The upper and lower ends of the feeding pipe are respectively provided with an upper opening and a lower opening, and a side opening is provided on one side of the feeding pipe. There are two adjusting mechanisms, which are respectively installed at the upper ends of the side openings. The adjusting mechanism is composed of a rotating disc, which is located at the upper ends of the side openings. The handle and the locking mechanism are installed on the upper end of the adjusting mechanism. The handle is composed of an inner handle cylinder and an outer adjusting cylinder. The locking mechanism is composed of an upper shell and a spring pressure plate. Both the upper shell and the spring pressure plate are arc-shaped and form a cylindrical shape.

[0006] In use, the upper opening of the feeding pipe of this device is connected to the discharge port of the processing equipment. Pressing the handle according to the discharge volume causes the eccentric rod to deflect, which in turn drives the rotating disc to rotate, simultaneously causing the baffle to deflect and open. The opening range of the baffle is adjusted according to the material quantity to ensure smooth discharge and prevent blockage caused by excessive material accumulation. Simultaneously, it can close the internal passage of the feeding pipe, facilitating the replacement of storage facilities. The baffle allows for convenient, staged adjustment of discharge efficiency, offering high operability. The baffle's eccentric, inclined design allows material to be discharged along its inclined surface after opening, facilitating discharge while guiding the material. When the handle is pressed, it simultaneously drives the locking mechanism to deflect, locking... The locking mechanism moves along the track within the arc frame. The arc frame has three-stage positioning ports. During the movement of the locking mechanism, the spring plate is squeezed and deformed into the upper shell. When the spring plate corresponds to the positioning port, it resets and locks in place to complete the limit position. The uppermost positioning port is in a closed state with a baffle. After deflecting downwards by 60 degrees, the baffle is in a half-open state. After deflecting downwards by 120 degrees, the baffle is fully open. At the same time, after the limit position is reached, the outer adjusting cylinder is rotated so that the screw thread enters between the upper shell and the spring plate. The screw limit prevents the spring plate from deforming, thus improving the positioning stability and avoiding damage to the locking structure caused by excessive weight of accumulated material. Through the above structural design, it is convenient to adjust the deflection angle of the baffle to achieve different working states. At the same time, the handle locks after the positioning adjustment to ensure stable operation of the device.

[0007] Preferably, the baffle is designed in an inclined state, and a limiting plate is provided on the inner side of the feed tube, with the inclined surface of the baffle abutting the lower end of the limiting plate.

[0008] Preferably, the upper end of the baffle is provided with side receiving plates on both sides, and the side receiving plates are connected to the inner side of the rotating disk by bolts. The outer side of the rotating disk is fixed with an outer fixed shaft, and the upper end of the outer fixed shaft is provided with an eccentric rod.

[0009] Preferably, both sides of the feeding tube are provided with brackets, and the outer end of the outer fixed shaft is rotatably mounted on the brackets, and the upper end of the eccentric rod is fixed at the connection between the inner handle and the upper shell.

[0010] Preferably, both sides of the feeding tube are embedded with arc frames, and positioning holes are equidistantly opened on the inner side of the arc frames. The arc frames and the rotating disk are concentric circles.

[0011] Preferably, a screw is fixed inside the outer adjusting cylinder, and the screw thread passes through the inner cylinder and the eccentric rod, with the outer end of the screw located between the upper shell and the spring pressure plate.

[0012] Preferably, the upper shell and the spring pressure plate are located within the arc frame, the spring pressure plate is adapted to the positioning port, the inner side of the upper shell is arrayed with limiting posts, the spring pressure plate is provided with a limiting port, and the limiting port is connected to the limiting post.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the design of a baffle, connects the upper opening of the feeding pipe of this device to the discharge port of the processing equipment. Pressing the handle according to the discharge volume causes the eccentric rod to deflect, which in turn drives the rotating disk to rotate, simultaneously causing the baffle to deflect and open. The opening range of the baffle can be adjusted according to the material volume to ensure smooth discharge and avoid blockage caused by excessive material accumulation. At the same time, it can close the internal passage of the feeding pipe, facilitating the replacement of the material storage device. The baffle allows for convenient staged adjustment of the discharge efficiency, making it highly operable. In addition, the baffle has an eccentric inclined design, which allows the material to be discharged along the inclined surface of the baffle after opening, facilitating discharge while guiding the material.

[0015] 2. This utility model also incorporates a locking mechanism. When the handle is pressed, it synchronously drives the locking mechanism to deflect. The locking mechanism moves along a track within the arc frame. The arc frame has three positioning ports. During its movement, the locking mechanism compresses the spring plate, causing it to deform and contract into the upper shell. When the spring plate aligns with the positioning port, it resets and engages to complete the limiting position. The uppermost positioning port is in a closed baffle state. After deflecting downwards by 60 degrees, the baffle is in a half-open state. After deflecting downwards by 120 degrees, the baffle is fully open. Simultaneously, after the limiting position is achieved, the outer adjusting cylinder is rotated to allow the screw thread to enter between the upper shell and the spring plate. The screw limiting position prevents deformation of the spring plate, improving positioning stability and avoiding damage to the locking structure caused by excessive material accumulation. Through the above structural design, the baffle deflection angle can be easily adjusted to achieve different working states. At the same time, the handle locks after positioning adjustment, ensuring stable operation of the device. Attached Figure Description

[0026] Working Principle: This embodiment provides an adjustable ash discharge valve device for a feeding pipe. In use, the upper opening 104 of the feeding pipe body 1 is connected to the discharge port of the processing equipment. Pressing the handle 5 according to the discharge volume causes the eccentric rod 303 to deflect, which in turn drives the rotating disk 302 to rotate, simultaneously causing the baffle 4 to deflect and open.
