Description

Technical Field

[0001] This utility model relates to the technical field of snowplow devices, and in particular to a snowplow sealing device. Background Technology

[0002] In existing snowplow devices, frequent pushing of the pusher tongue leads to several issues. First, residual molten material accumulates on the pusher tongue, increasing its surface roughness and exacerbating wear on the graphite packing used for sealing. Second, the pusher tongue heats up with frequent pushing, potentially scalding the packing and reducing its lifespan. Wear on the sealing packing in existing snowplow devices leads to material leakage, requiring replacement as the pressure cannot be adjusted further. However, replacement is inconvenient in practice, significantly increasing labor intensity. Furthermore, wear on the sealing packing causes ash and material leakage in the snowplow device, as positive pressure generated after the pusher tongue is pushed in can lead to ash and material leakage. Therefore, we propose a snowplow sealing device. Utility Model Content

[0003] This invention provides a sealing device for a snowman pusher, which solves the above-mentioned technical problems.

[0004] The present invention provides the following solution to the above-mentioned technical problems: a snowman-pushing sealing device, comprising a pushing tongue, a casting refractory wall outside the pushing tongue, a protective outer shell outside the pushing tongue, the protective outer shell being fixedly connected to the casting refractory wall, a metal nozzle fixedly connected to the outer wall of the protective outer shell, a high-pressure hose fixedly connected to the metal nozzle, a solenoid valve installed on the high-pressure hose, a fixed flange fixedly installed on the outer wall of the protective outer shell, a second flange installed on the fixed flange by hexagonal bolts, a clamping flange installed on the second flange by fastening bolts, a first sealing packing between the fixed flange and the second flange, the first sealing packing being connected to an adjusting mechanism, a second sealing packing being slidably fitted between the second flange and the clamping flange, and both the first and second sealing packings being slidably fitted with the pushing tongue.

[0005] Preferably, the adjusting mechanism includes baffles fixedly installed on the outer walls of the fixed flange and the second flange, a pressure plate clamped and fixed between the two baffles, a clamping bolt threaded through the pressure plate, a metal pressure block rotatably installed at the end of the clamping bolt, and the metal pressure block being fixedly connected to the outer wall of the first sealing packing.

[0006] Preferably, a displacement sensor is fixedly inserted through the upper part of the sheath shell.

[0007] Preferably, the second-layer flange and the clamping flange are movably sleeved on the outer wall of the pusher tongue.

[0008] Preferably, the cross-section of the second sealing packing is trapezoidal, and the contact surfaces of the second flange, the compression flange and the second sealing packing are all inclined surfaces.

[0009] The beneficial effects of this utility model are:

[0010] 1. By setting up a double-layer adjustable seal, after a period of use, only periodic tightening of the bolts is needed to compress the seal, increasing the service life of the first sealing packing. At the same time, a second sealing packing is set up for auxiliary sealing, enhancing the sealing effect.

[0011] 2. By setting up a blowing device, when the pusher tongue moves forward, the solenoid valve opens, and compressed air blows cold air into the outer casing through the high-pressure hose and metal pipe. This can blow the ash into the inner side of the castable wall to prevent ash leakage. At the same time, the blowing also cools the pusher tongue, preventing it from getting too hot after it is pushed out and damaging the first and second sealing packings, thus extending their service life. The blowing also cleans the moving pusher tongue, removing any residual clinker particles.

[0020] The following is in conjunction with the appendix Figure 1-4 The principles and features of this utility model are described below. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0021] like Figure 1-4 As shown, this utility model discloses a snowman sealing device, including a pusher tongue 2, a castable refractory wall surrounding the pusher tongue 2, a protective outer shell 3 covering the pusher tongue 2, the protective outer shell 3 being fixedly connected to the castable refractory wall, a metal nozzle 4 being fixedly connected to the outer wall of the protective outer shell 3, a high-pressure hose 5 being fixedly connected to the metal nozzle 4, a solenoid valve 6 being installed on the high-pressure hose 5, a fixed flange 7 being fixedly installed on the outer wall of the protective outer shell 3, a second flange 8 being installed on the fixed flange 7 via hexagonal bolts 9, a clamping flange 11 being installed on the second flange 8 via fastening bolts 10, a first sealing packing 12 being provided between the fixed flange 7 and the second flange 8, the first sealing packing 12 being connected to an adjusting mechanism, and a second sealing packing 13 being slidably fitted between the second flange 8 and the clamping flange 11. All sealing packing 13 slides with the pusher tongue 2. The double flange 8 and the clamping flange 11 are respectively movably sleeved on the outer wall of the pusher tongue 2. This device adds a double-layer adjustable seal, which still has adjustment margin after the seal wears for a period of time, so as to extend the service life of the sealing components and thus achieve the purpose of saving costs. A spraying device is added. The spraying device can be controlled by a switch and feedback from the displacement sensor 1. It is opened when the snowman device moves, and high-pressure gas is sprayed to clean the moving pusher tongue 2, cleaning away the residual clinker particles on the pusher tongue 2, ensuring that the surface of the pusher tongue 2 is smooth. The high-pressure air blown out can also block the hot air carrying particles blown from under the grate. In addition, the cooling air blown out can also cool down the pusher tongue, reduce the temperature of the pusher tongue 2 and extend the seal life.

[0022] Specifically, the adjustment mechanism includes baffles 14 fixedly installed on the outer walls of the fixed flange 7 and the second flange 8. A pressure plate 15 is clamped and fixed between the two baffles 14. A clamping bolt 16 is threaded through the pressure plate 15. A metal pressure block 17 is rotatably installed at the end of the clamping bolt 16. The metal pressure block 17 is fixedly connected to the outer wall of the first sealing packing 12. Rotating the clamping bolt 16 can indirectly drive the first sealing packing 12 to move, adjust the position of the first sealing packing 12, and make the first sealing packing 12 in close contact with the pusher tongue 2 to achieve sealing.

[0023] Furthermore, a displacement sensor 1 is fixedly inserted through the upper part of the sheath shell 3. The displacement sensor 1 is used to monitor the moving distance of the pusher tongue 2. After the pusher tongue 2 moves to the set start distance, the feedback control opens the solenoid valve 6, causing compressed air to be sprayed out from the metal nozzle 4 to cool the pusher tongue 2 and blow away the residual clinker particles on the pusher tongue.

[0024] Furthermore, the second sealing packing 13 has a trapezoidal cross-section, and the contact surfaces of the second flange 8, the clamping flange 11 and the second sealing packing 13 are all inclined. This design also allows the clamping flange 11 to move toward the second flange 8 by tightening the fastening bolts 10. The clamping flange 11 and the second flange 8 cooperate to squeeze the second sealing packing 13, so that the second sealing packing 13 is pressed against the pusher tongue.

[0025] Working principle:

[0026] When the device is started, the pusher tongue 2 moves towards the inside of the casting wall. After the pusher tongue 2 moves a set distance, the displacement sensor 1 controls the opening of the solenoid valve 6. Compressed air is introduced from the high-pressure hose 5 into the metal nozzle 4 and then sprayed out to sweep the pusher tongue 2, removing clinker particles from its surface and cooling the pusher tongue 2. After the first sealing packing 12 is worn due to the movement of the pusher tongue 2, it can be moved by rotating the clamping bolt 16 to move the first sealing packing 12 under the metal pressure block 17, so that the first sealing packing 12 is tightly sealed with the pusher tongue 2 again.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
