Description

Technical Field

[0001] This utility model belongs to the field of grate cleaning technology, specifically relating to a grate material cleaning device. Background Technology

[0002] The grate bed is the main component of the grate cooler, comprising several grate boxes. Each grate box contains several lower grate plates fixed at equal intervals. The grate plates typically have support supports and multiple parallel V-shaped bent plates located within the support supports. These bent plates are designed so that the openings of two bent plates are opposite, one opening upwards and the other downwards, alternating in this manner. The two side plates of the upward-opening bent plate are connected to the inner bottoms of the two downward-opening bent plates located on either side of that bent plate, forming an interlaced structure. Adjacent bent plates... A sloping groove is formed between the plates. During the operation of the grate cooler, material and dust will accumulate in the sloping groove. Because the grate cooler box is relatively narrow, it is very difficult to manually enter the sloping groove of the grate cooler box for cleaning. Moreover, because the accumulated material and dust have a certain degree of adhesion, they can adhere to the surface of the object through electrostatic action, chemical bonding or physical adsorption. After a long period of accumulation, the dust particles and the dust and the grate plate surface will form a firm bond, making cleaning difficult. It is not easy to completely remove the accumulated material by using vacuum equipment alone. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a grate box material cleaning device to solve the problems mentioned in the background art.

[0004] This utility model provides a grate cleaning device, including a housing with a negative pressure device installed inside, a suction head connected to the negative pressure device via a suction pipe to extend into the grate to clean the accumulated material on the inclined channel, and a dust collection box connected between the suction pipe and the negative pressure device for collecting the accumulated material sucked up by the suction head. The housing is also equipped with a shovel for loosening the accumulated material on the inclined channel. In use, the accumulated material on the inclined channel is first loosened by the shovel, and then a negative pressure area is formed in the dust collection box under the drive of the negative pressure device. The suction head sucks the loosened material along the suction pipe into the dust collection box for collection.

[0005] Preferably, the suction end of the suction head extends to the outside of the housing, and the shovel is located below the suction head. When the shovel loosens the accumulated material on the inclined groove and shovels it onto the shovel, the suction head can suck up the accumulated material on the shovel.

[0006] Preferably, the shape of the shovel is adapted to the shape of the inclined groove formed by two adjacent grates.

[0007] Preferably, the shovel is detachably connected to the housing.

[0008] Preferably, the dust collection box is provided with a dust collection bag connected to the dust collection pipe. The dust collection bag is used to collect accumulated material and prevent it from entering the negative pressure equipment, thereby protecting the negative pressure equipment from damage.

[0009] Preferably, a handle that is easy for a person to hold is fixedly connected to the side of the housing away from the suction head. An elastic element is provided on the side of the handle near the housing. This elastic element is used to ensure that the shovel is always in contact with the grate as the shovel moves along the grate and cleans the accumulated material in the chute, thereby ensuring the effect of cleaning the accumulated material.

[0010] Preferably, the handle is also equipped with a controller connected to the negative pressure device for controlling the start and stop of the negative pressure device.

[0011] The beneficial effects of this utility model are: by combining the suction head and the shovel, when cleaning the accumulated material on the grate, the shovel is first used to loosen the accumulated material on the inclined channel, and then the negative pressure equipment and suction head are used to suck it up, which can significantly improve the cleaning efficiency of the accumulated material. Compared with the traditional method of manually entering the grate box for cleaning, this device can remove the accumulated material more quickly and thoroughly, reducing cleaning time and labor costs.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0019] The existing grate cleaning device mainly includes a housing 2 with a negative pressure device 1 installed inside, a suction head 5 connected to the negative pressure device 1 via a dust extraction pipe 3 to extend into the grate to clean the accumulated material on the inclined groove 4, and a dust collection box 6 connected between the dust extraction pipe 3 and the negative pressure device 1 to collect the accumulated material sucked up by the suction head 5. During downtime, workers enter the air chamber of the grate cooler and use the aforementioned dust extraction device to suck up the accumulated dust and material on the grate plate 14 and other components to clean the grate. The above is an introduction to the existing grate cleaning device.

[0020] As can be seen from the above, the existing grate box material cleaning device has the following defects when in use. Due to the narrowness of the grate cooler box, it is very difficult for manual personnel to enter the inclined groove 4 of the grate cooler box for cleaning. Moreover, because the accumulated material and dust have a certain degree of adhesion, they can adhere to the surface of the object through electrostatic action, chemical bonding or physical adsorption. After long-term accumulation, a firm bond will form between the dust particles and between the dust and the surface of the grate plate 14, making cleaning difficult. It is not easy to completely remove the accumulated material by using a vacuum cleaner alone. Based on the above problems, the present invention adopts the following improvement method to solve them.

[0021] like Figure 1-5 As shown, the grate cleaning device includes a housing 2 with a negative pressure device 1 installed inside, a suction head 5 connected to the negative pressure device 1 via a suction pipe 3 to extend into the grate to clean the accumulated material on the inclined groove 4, and a dust collection box 6 connected between the suction pipe 3 and the negative pressure device 1 for collecting the accumulated material sucked up by the suction head 5. The housing 2 is also equipped with a shovel 7 for loosening the accumulated material on the inclined groove 4. In use, the accumulated material on the inclined groove 4 is first loosened by the shovel 7, and then a negative pressure area is formed in the dust collection box 6 under the drive of the negative pressure device 1. The suction head 5 sucks the loosened material along the suction pipe 3 into the dust collection box 6 for collection. Compared with the existing operation of workers entering the grate to clean the grate plate 14, the present invention combines the shovel 7 and the suction head 5 to clean the accumulated material, which is more convenient and can significantly improve the cleaning efficiency of the accumulated material.

[0022] Furthermore, such as Figure 1-5 As shown, the suction end of the suction head 5 extends to the outside of the housing 2, and the shovel 7 is located below the suction head 5 and is positioned in conjunction with the shovel 7. When the shovel 7 loosens the accumulated material on the inclined groove 4 and shovels it onto the shovel 7, the suction head 5 can promptly suck up the accumulated material on the shovel 7, thereby improving the cleaning efficiency of the grate 14.

[0023] Furthermore, such as Figure 5As shown, the shape of the shovel 7 is adapted to the shape of the inclined groove 4 formed by two adjacent grate plates 14, so that the shovel 7 can more effectively loosen and collect the accumulated material in the inclined groove 4, improve the cleaning effect of the shovel 7, and reduce the resistance that may be encountered during the cleaning process. As shown in the figure, when cleaning a grate box with a V-shaped inclined groove 4 formed by two adjacent grate plates 14, the shovel 7 can be designed with a V-shaped cross section. Secondly, when cleaning a grate box with other shapes formed by two adjacent grate plates 14, such as a U-shaped inclined groove 4, the shovel 7 can be designed with a U-shaped cross section, so that the shovel 7 can clean the accumulated material on the inclined groove 4 and the surface of the two adjacent grate plates 14 at the same time, thereby further improving the cleaning efficiency of the grate box.

[0024] Furthermore, such as Figure 1-4 As shown, the shovel 7 is detachably connected to the housing 2. The shovel 7 and the housing 2 can be connected by bolts 8. As shown, the side of the shovel 7 closest to the housing 2 can be bent inward to form a groove 9, which is adapted to the bottom plate of the housing 2. The bottom plate of the housing 2 is inserted along the groove 9, and then the bolts 8 are used to fix the shovel 7 to the bottom plate of the housing 2, which facilitates the disassembly of the shovel 7. The shovel 7 can be replaced with a matching one according to different models of grate boxes.

[0025] Furthermore, such as Figure 2 As shown, the dust collection box 6 has a dust collection bag 10 connected to the dust collection pipe 3 inside. The dust collection bag 10 is used to collect accumulated material and prevent it from entering the negative pressure device 1, thereby protecting the negative pressure device 1 from damage. The end of the dust collection bag 10 near the suction head 5 is fitted onto the dust collection pipe 3. To ensure the stability of the dust collection bag 10, a rope can be used to tie the dust collection bag 10 to the dust collection pipe 3. When the dust collection bag 10 is full of accumulated material, the rope can be untied to remove the dust collection bag 10 from the dust collection pipe 3 for cleaning.

[0026] Furthermore, such as Figure 1-4 As shown, a handle 11 is fixedly connected to the side of the housing 2 away from the suction end of the suction head 5, which is easy for a person to hold. An elastic element 12 is provided on the side of the handle 11 close to the housing 2. The elastic element 12 can be a spring. When a person holds the handle 11 and drives the shovel 7 to move along the grate 14 and clean the accumulated material in the inclined groove 4, a downward force is applied to the handle 11. The shovel 7 can always be in contact with the grate 14, thereby ensuring the effect of cleaning the accumulated material.

[0027] Furthermore, such as Figure 1-4 As shown, the handle 11 is also equipped with a controller 13 connected to the negative pressure device 1. The controller 13 allows the user to start and stop the negative pressure device 1 at any time, improving the flexibility and convenience of operation and improving cleaning efficiency. The controller 13 is also equipped with a rechargeable power supply for supplying power to the negative pressure device 1.
