Description

Technical Field

[0001] The present application relates to the technical field of silo blockage clearing devices, and more specifically, to an anti-blockage silo blockage clearing spray device. Background Art

[0002] In the prior art, during the silo clearing process, the silo clearing spray device used is a spray gun. Since materials are stored inside the silo for a long time, and most of the materials are in powder form, the spray gun for clearing is installed inside the silo wall. The powder material will enter the spray gun, and over time it will clog the nozzle, resulting in the inability to spray gas, affecting the effect of clearing. The spray gun is generally installed on the silo wall. The silo body is relatively high and large. If the nozzle is blocked, it will be very troublesome to repair it, and it will take a lot of manpower and material resources to clear the blockage of the nozzle. Utility Model Content

[0003] The main purpose of the utility model is to provide an anti-blocking silo clearing spray device, aiming to solve the technical problem that the silo clearing spray device in the prior art is prone to blockage.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: an anti-blocking silo clearing and spraying device, which includes:

[0005] An injection sleeve, wherein an injection chamber is formed inside the injection sleeve, an injection outlet communicated with the injection chamber is formed at a first end of the injection sleeve in an axial direction, and an air inlet communicated with the injection chamber is formed on a side wall of the injection sleeve;

[0006] a movable top core, the movable top core being arranged in the injection chamber and being movable along the axis direction of the injection sleeve between a blocking position and a releasing position, wherein the movable top core blocks the injection outlet at the blocking position and releases the blocking of the injection outlet at the releasing position, so that the gas entering the injection chamber from the air inlet can be ejected from the injection outlet;

[0007] An elastic mechanism is arranged in the injection chamber and cooperates with the movable top core to keep the movable top core in the blocking position through elastic force. When gas is introduced into the injection chamber through the air inlet, the gas can act on the elastic mechanism to overcome the elastic force and move the movable top core to the release position.

[0008] Furthermore, a circle of baffles is formed at one end of the movable top core away from the air inlet, and the baffle is in sealing contact with the inner wall of the injection sleeve. One end of the elastic mechanism abuts against one side of the end of the baffle away from the air inlet, and the other end of the elastic mechanism abuts against the end wall of the second end of the injection sleeve in the axial direction.

[0009] Furthermore, the anti-blocking silo clearing and spraying device includes an elastic sealing ring arranged on the outer side of the baffle, and the baffle is in sealing contact with the inner wall of the spray sleeve through the elastic sealing ring.

[0010] Furthermore, a mounting opening is formed at the second end of the injection sleeve in the axial direction, and an end cover for sealing the mounting opening is detachably mounted at the mounting opening, and the end cover serves as the end wall.

[0011] Furthermore, the injection sleeve forms an exhaust port connecting the interior of the injection chamber with the exterior of the injection sleeve at a position between the baffle and the end wall.

[0012] Furthermore, the anti-blocking silo clearing injection device includes a muffler installed at the exhaust port.

[0013] Furthermore, the anti-blocking silo clearing injection device also includes a guide ring mounted on the movable top core, the guide ring is provided with a through hole extending axially therethrough, the guide ring is in contact with the inner wall of the injection sleeve, and the guide ring is closer to the injection outlet than the air inlet and the baffle.

[0014] Furthermore, the elastic mechanism is a spring.

[0015] Furthermore, the injection sleeve forms a tapered inner wall surface which gradually narrows toward the injection outlet at a position adjacent to the injection outlet, and one end of the movable top core facing the injection outlet is a tapered head adapted to the tapered inner wall surface.

[0016] Furthermore, the anti-blocking silo clearing injection device also includes an air intake guide pipe detachably connected to the air inlet.

[0017] The beneficial effects of the anti-blocking silo clearing spray device provided in the present application are:

[0018] Since the anti-blocking silo clearing injection device provided by the embodiment of the utility model is provided with a movable top core and an elastic mechanism, the movable top core is arranged in the injection chamber and can move between a blocking position and a releasing position along the axial direction of the injection sleeve. In the blocking position, the movable top core blocks the injection outlet, and in the releasing position, the movable top core releases the blockage of the injection outlet, so that the gas entering the injection chamber from the air inlet can be ejected from the injection outlet. The elastic mechanism and the air inlet can be used to pass the gas into the injection chamber. The movable top core is controlled to be in the blocking position or the releasing position. Therefore, when the anti-blocking silo clearing injection device is installed on the silo wall, when the anti-blocking silo clearing injection device is not working, the movable top core can block the injection outlet to avoid the situation that the material in the silo blocks the injection outlet. When performing the clearing work, it is only necessary to introduce clearing gas from the air inlet so that the gas can act on the elastic mechanism to overcome the elastic force and move the movable top core to the releasing position, thereby ensuring that the gas can be normally ejected from the injection outlet after entering the injection chamber to perform the silo clearing operation.

[0046] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0047] See also Figures 1 to 4 The utility model provides an anti-blocking silo clearing spray device, which includes:

[0048] The spray sleeve 100 has a spray chamber 101 formed inside the spray sleeve 100, a spray outlet 102 (nozzle) communicating with the spray chamber 101 is formed at a first end of the spray sleeve 100 in the axial direction, and an air inlet 103 communicating with the spray chamber 101 is formed on a side wall of the spray sleeve 100;

[0049] The movable top core 200 is disposed in the injection chamber 101 and can move along the axis direction of the injection sleeve 100 between a blocking position and a releasing position. In the blocking position, the movable top core 200 blocks the injection outlet 102. In the releasing position, the movable top core 200 releases the blocking of the injection outlet 102, so that the gas entering the injection chamber 101 from the air inlet 103 can be ejected from the injection outlet 102;

[0050] The elastic mechanism is arranged in the injection chamber 101 and cooperates with the movable top core 200 to keep the movable top core 200 in the blocking position through the elastic force. When the gas is introduced into the injection chamber 101 through the air inlet 103, the gas can act on the elastic mechanism to overcome the elastic force and move the movable top core 200 to the release position.

[0051] Since the anti-blocking silo clearing and spraying device provided by the embodiment of the utility model is provided with a movable top core 200 and an elastic mechanism, the movable top core 200 is arranged in the spray chamber 101 and can move between a blocking position and a releasing position along the axial direction of the spray sleeve 100. In the blocking position, the movable top core 200 blocks the spray outlet 102. In the releasing position, the movable top core 200 releases the blockage of the spray outlet 102, so that the gas entering the spray chamber 101 from the air inlet 103 can be sprayed out from the spray outlet 102. The elastic mechanism and the air inlet 103 can control the effect of the gas entering the spray chamber 101. The movable top core 200 is controlled to be in the blocking position or the releasing position. Therefore, when the anti-blocking silo clearing injection device is installed on the silo wall, when the anti-blocking silo clearing injection device is not working, the movable top core 200 can block the injection outlet 102 to prevent the material in the silo from blocking the injection outlet 102. When clearing the blockage, it is only necessary to introduce clearing gas from the air inlet 103 so that the gas can act on the elastic mechanism to overcome the elastic force and move the movable top core 200 to the releasing position, ensuring that the gas can enter the injection chamber 101 and then be normally ejected from the injection outlet 102 to perform the silo clearing operation.

[0052] See also Figure 1 and Figure 2 According to an embodiment of the present invention, a peripheral stop 201 is formed at one end of the movable top core 200 away from the air inlet 103 .

[0053] In this embodiment, the baffle 201 is in sealing contact with the inner wall of the injection sleeve 100, one end of the elastic mechanism abuts against one side of the end of the baffle 201 away from the air inlet 103, and the other end of the elastic mechanism abuts against the end wall of the second end of the injection sleeve 100 in the axial direction.

[0054] According to an embodiment of the present invention, the elastic mechanism is a spring 1 , or a replaceable structure (element) similar to the spring 1 .

[0055] In this embodiment, the spring 1 can be sleeved on the movable top core 200 , with one end of the spring 1 abutting against the stopper 201 , and the other end of the spring 1 abutting against the end wall of the second end of the injection sleeve 100 in the axial direction.

[0056] See also Figure 1 and Figure 2 According to a preferred embodiment of the utility model, the anti-blocking silo clearing and spraying device includes an elastic sealing ring 2 arranged on the outside of the baffle 201, and the baffle 201 is in sealing contact with the inner wall of the spray sleeve 100 through the elastic sealing ring 2.

[0057] According to an embodiment of the present invention, the elastic sealing ring 2 can be made of a rubber ring or other material.

[0058] Of course, as other embodiments, the outer side of the baffle 201 may be directly in sealing contact with the inner wall of the injection sleeve 100. However, considering the wear of the baffle 201 and the impact on its own sealing performance, as mentioned above, it is preferred that the baffle 201 is in sealing contact with the inner wall of the injection sleeve 100 through the elastic sealing ring 2.

[0059] According to an embodiment of the present invention, a mounting opening is formed at the second end of the injection sleeve 100 in the axial direction, and an end cover 3 for sealing the mounting opening is detachably mounted at the mounting opening.

[0060] In this embodiment, the end cover 3 serves as the end wall of the second end of the injection sleeve 100 in the axial direction. The end cover 3 can be installed on the second end of the injection sleeve 100 by means of bolts, screws 4 (specifically hexagon socket screws, etc.).

[0061] Of course, as another embodiment, the second end of the injection sleeve 100 can also be directly integrally formed with an end wall (end cover 3).

[0062] See also Figure 1 According to an embodiment of the present invention, the injection sleeve 100 forms an exhaust port 104 between the baffle 201 and the end wall, which connects the inside of the injection chamber 101 with the outside of the injection sleeve 100 .

[0063] In this embodiment, because the baffle 201 is in sealed contact with the inner wall of the injection sleeve 100, there is gas in the local chamber between the baffle 201 and the end of the injection sleeve 100. The exhaust port 104 is provided to ensure that when the movable top core 200 moves toward the second end of the injection sleeve 100, the local chamber between the baffle 201 and the end of the injection sleeve 100 becomes smaller, and the gas therein can be discharged, thereby not affecting the movement of the movable top core 200 toward the second end of the injection sleeve 100.

[0064] According to an embodiment of the utility model, the anti-blocking silo clearing injection device includes a muffler 5 installed at the exhaust port 104 .

[0065] In this embodiment, since the muffler 5 is provided, the gas in the local chamber between the baffle 201 and the end of the injection sleeve 100 can pass through the exhaust port 104 and finally be discharged through the muffler 5, so that the local chamber between the baffle 201 and the end of the injection sleeve 100 can have a very good silent effect when discharging the gas, avoiding the generation of airflow noise.

[0066] However, it is understandable that, as other embodiments, even if the muffler 5 is not provided, it will fall within the protection scope of the present utility model.

[0067] See also Figures 1 to 3According to an embodiment of the utility model, the anti-blocking silo clearing and spraying device also includes a guide ring 300 mounted on the movable top core 200.

[0068] In this embodiment, a through hole 301 is provided on the guide ring 300 which passes through the guide ring 300 along its axial direction. The guide ring 300 contacts the inner wall of the injection sleeve 100. The guide ring 300 is closer to the injection outlet 102 than the air inlet 103 and the baffle 201. The through hole 301 can ensure that the gas flowing into the injection chamber 101 from the air inlet 103 reaches the injection outlet 102 through the through hole 301.

[0069] In this embodiment, the number of the through holes 301 is preferably multiple, and the multiple through holes 301 can be arranged in a ring-like manner and at intervals in the circumferential direction of the guide ring 300.

[0070] According to one embodiment of the utility model, the spray sleeve 100 forms a conical inner wall surface 105 which gradually narrows toward the spray outlet 102 at a position adjacent to the spray outlet 102 , and the end of the movable top core 200 facing the spray outlet 102 is a conical head 202 adapted to the conical inner wall surface 105 .

[0071] In this embodiment, the conical head 202 is in sealing contact with the conical inner wall surface 105, so that the movable top core 200 can better block the injection outlet 102 at the blocking position.

[0072] According to one embodiment of the utility model, the anti-blocking silo clearing injection device also includes an air intake guide pipe 6 detachably connected to the air inlet 103. The air intake guide pipe 6 can be specifically screwed to the portion of the injection sleeve 100 located at the air inlet 103 to facilitate the introduction of silo clearing gas.

[0073] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
