Description

Technical Field

[0001] This utility model relates to a valve, specifically a non-powered ash discharge valve. Background Technology

[0002] Ash discharge valves are key components in dust removal equipment for ash discharge, air supply, and feeding in other equipment. They are suitable for unloading powdery and granular materials and are widely used in environmental protection, metallurgy, chemical, building materials, non-ferrous metals, grain, and food industries. Existing ash discharge valves come in many types. Most common automatic ash discharge valves are electric or pneumatic. While automatic ash discharge valves offer better efficiency, their high cost makes them somewhat overkill for use in dry or easily dusty environments, increasing operating costs. Manual gate-type ash discharge valves increase the workload of operators, and manual operation can lead to incomplete gate return, causing dust to escape. Dust is harmful to operators. Therefore, developing a non-powered, sealed ash discharge valve is a pressing technical problem. Utility Model Content

[0003] To address the problems of high energy consumption and cumbersome operation of existing ash discharge valves in the background art, this utility model provides an ash discharge valve that is not powered.

[0004] The technical solution of this utility model is: a non-powered ash discharge valve, including a valve body, wherein the valve body is provided with a feed inlet and a medium channel; and further comprising:

[0005] A rotating shaft is mounted on the valve body and rotates in conjunction with the valve body.

[0006] An impeller is mounted on a rotating shaft and is linked to the rotating shaft. The impeller has multiple blades. The medium entering through the feed inlet interacts with the blades on one side of the rotating shaft, causing the blades to rotate and open the medium channel.

[0007] A cam is mounted on a rotating shaft and is linked to the rotating shaft.

[0008] The adjusting mechanism, in conjunction with the cam, is used to adjust the rotational speed of the impeller.

[0009] As a further improvement of this utility model, the adjusting mechanism includes a pressure rod, which is hinged to the valve body and can rotate relative to the valve body, and the pressure rod is in contact with the outer surface of the cam.

[0010] As a further improvement to this utility model, it also includes:

[0011] Adjustment seat, located on the valve body;

[0012] An elastic element is provided inside the adjusting seat. The elastic element abuts against the pressure rod and has a tendency to drive the pressure rod to press against the outer surface of the cam.

[0013] As a further improvement of this utility model, it also includes an adjusting bolt, which is disposed on the adjusting seat and threadedly connected to the adjusting seat. The adjusting bolt abuts against the elastic element to adjust the elastic force of the elastic element pressing against the pressure rod.

[0014] As a further improvement of this utility model, the cam is provided with a protrusion, which protrudes from the outer surface of the cam.

[0015] As a further improvement of this utility model, it also includes a limiting mechanism, which cooperates with the cam to limit the rotation of the cam.

[0016] As a further improvement of this utility model, the limiting mechanism includes a push rod and a driving member. The driving member is connected to the push rod and is used to drive the push rod to reciprocate. The push rod abuts against the outer surface of the cam and / or the protrusion and cooperates with the outer surface of the protrusion to limit the rotation of the cam.

[0017] As a further improvement of this utility model, the outer surface of the protrusion is arc-shaped.

[0018] As a further improvement of this utility model, the valve body is provided with an inclined surface, which is located at the feed inlet and causes the medium at the feed inlet to flow to the blades on one side of the rotating shaft of the impeller, so that the blades rotate to open the medium channel.

[0019] As a further improvement of this utility model, it also includes a pressure cap, wherein the rotating shaft is fitted with a packing seal, the packing seal is fitted with a packing pressure plate, and the pressure cap is located at the other end of the rotating shaft opposite to the cam.

[0020] The beneficial effects of this utility model are that the impeller rotates when the medium enters through the feed inlet, and the impeller can be rotated to open the medium channel without the need for an additional power source. The structure is simple, the cost is low, and the energy consumption is low. The rotation speed of the impeller can be adjusted by adjusting the structure settings, making it suitable for different scenarios and thus making the product widely applicable.

Detailed Implementation

[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0026] Depend on Figure 1 Combination Figure 2-3 As shown, a non-powered ash discharge valve includes a valve body 1, on which a feed inlet 11 and a medium channel 12 are provided; it also includes:

[0027] Rotating shaft 2 is mounted on valve body 1 and rotates in conjunction with valve body 1;

[0028] Impeller 3 is mounted on rotating shaft 2 and is linked to rotating shaft 2. Impeller 3 is provided with multiple blades 31. The medium entering through feed inlet 11 interacts with the blades 31 on one side of rotating shaft 2, causing the blades 31 to rotate and open medium channel 12.

[0029] Cam 4 is mounted on rotating shaft 2 and is linked to rotating shaft 2;

[0030] The adjusting mechanism 5, in conjunction with the cam 4, is used to adjust the rotation speed of the impeller 3. The beneficial effects of this invention are that the medium entering through the feed inlet causes the impeller to rotate, opening the medium channel even without an additional power source. It features a simple structure, low cost, and low energy consumption. The impeller's rotation speed can be adjusted through the adjustable structure, making it suitable for various scenarios and resulting in a wide range of product applications. Specifically, when the ash material enters through the upper feed inlet, its weight and height create potential energy that directly impacts the impeller. By offsetting the feed inlet to one side, the impact is directed only to one side of the blades, ensuring the blades rotate continuously in one direction.

[0031] The adjusting mechanism 5 includes a pressure rod 51, which is hinged to the valve body 1 and can rotate relative to the valve body 1. The pressure rod 51 is in contact with the outer surface of the cam 4. The rotational speed of the impeller is adjusted by the frictional force provided by the pressure rod. The structure is simple and the adjustment is convenient and reliable.

[0032] This utility model also includes:

[0033] Adjustment seat 52 is located on valve body 1;

[0034] An elastic element 53 is disposed within the adjusting seat 52. The elastic element 53 abuts against the pressure rod 51 and has a tendency to drive the pressure rod 51 to press against the outer surface of the cam 4. Specifically, it also includes an adjusting bolt 54, disposed on the adjusting seat 52 and threadedly connected to it. The adjusting bolt 54 abuts against the elastic element 53 to adjust the elastic force of the elastic element 53 pressing against the pressure rod 51. Specifically, the elastic element is a spring. The adjusting bolt increases and decreases the spring force. The spring acts on the pressure rod, and the pressure rod acts on the cam. The magnitude of the spring force directly affects the friction between the pressure rod and the cam. A greater friction force results in a lower impeller speed, and a lower friction force results in a higher impeller speed. When the impeller reaches the... Figure 1 At the middle position, the impeller experiences the greatest force, and at this point, the cam and pressure rod are in contact at their highest point.

[0035] The cam 4 is provided with a protrusion 41, which protrudes from the outer surface of the cam 4. This structure ensures that the pressure rod and the cam (protrusion) are reliably engaged.

[0036] This utility model also includes a limiting mechanism 6, which cooperates with the cam 4 to limit the rotation of the cam 4. Specifically, the limiting mechanism 6 includes a push rod 61 and a driving member 62. The driving member 62 is connected to the push rod 61 and is used to drive the push rod 61 to reciprocate. The push rod 61 abuts against the outer surface of the cam 4 and / or the protrusion 41 and cooperates with the outer surface of the protrusion 41 to limit the rotation of the cam 4. More specifically, the outer surface of the protrusion 41 is arc-shaped. More specifically, the driving member can be a cylinder, or of course, a motor or a hydraulic cylinder; taking a cylinder as an example, when air enters through the small opening at the top of the cylinder (when air enters through the rodless chamber), the push rod moves downward rapidly and acts on the cam. Because the protrusion is arc-shaped, it becomes tighter as it rotates; the limiting mechanism of the cylinder is adjusted so that the impeller stops precisely at... Figure 1 The middle position is also the closed position, meaning the medium channel is closed. Of course, in actual operation, sensors or other sensing elements can be used to control the blades to stop at the desired position. To start operation, air enters through the small port below the cylinder (intake from the rod chamber), causing the push rod to move upwards quickly away from the cam, thus starting operation.

[0037] The valve body 1 is provided with an inclined surface 13, which is located at the feed inlet 11 and causes the medium flowing from the feed inlet 11 to the blades 31 on one side of the rotating shaft of the impeller 3, causing the blades 31 to rotate and open the medium passage 12. This structure facilitates the medium to open the impeller and control the impeller rotation. Even without power, the impeller can be reliably rotated. The structure is simple, saves production costs, and is easy to operate.

[0038] This utility model also includes a pressure cap 71, a packing seal 72 is fitted over the rotating shaft 2, a packing pressure plate 73 is fitted over the packing seal 72, and the pressure cap 71 is located at the other end of the rotating shaft 2 opposite to the cam 4. This structure ensures reliable sealing of the product.
