Description

Technical Field

[0001] The utility model relates to the field of aerated concrete block production equipment, in particular to an automatic cleaning device for a suction cover of an aerated block cutting machine. Background Art

[0002] During the production process of aerated blocks, after the cast blank has been cured and reaches the cutting strength, the blank is flipped and demoulded and sent to the longitudinal cutting machine and cross-cutting machine in sequence by a trolley for six-sided cutting. The crust is automatically removed during the cutting operation to make the appearance size of the blank standard and meet the process requirements. After the top surface cutting is completed, the waste blank on the top surface is adsorbed and cleaned by the suction hood on the top of the cross-cutting machine. Working principle of the suction hood: The suction hood structure is a metal box with four closed sides and the top surface. A fan is installed on the top surface. The air inlet of the fan is connected to the box body, and the air outlet of the fan is exhausted to the atmosphere. The bottom surface of the suction hood is a metal grid structure covered with a metal filter on the outside. The metal filter is consistent in size with the upper surface of the aerated block blank. After the aerated block is cut, the suction hood descends to the upper surface of the block. The hood fan draws air from the chamber, creating negative pressure that acts on the cut scrap skin through the hood filter, firmly sucking it up. After the block carriage moves forward and leaves its original position, the hood fan stops, the negative pressure disappears, and the scrap skin loses suction and falls into the waste chute. In actual production, the hood filter is often clogged with scrap debris, resulting in insufficient suction. The scrap on the top surface cannot be cleaned, seriously affecting subsequent processes or even interrupting production. Utility Model Content

A suction hood fan 2 is arranged on the outer surface of the suction hood box body 1, and the suction hood fan 2 is connected to the suction hood box body 1 through an air intake duct 2-1. The air intake duct 2-1 is an inverted U-shaped duct, and both ends of the air intake duct 2-1 are respectively connected to the suction hood box body 1.

[0028] When the suction hood filter is clogged with scraps, resulting in insufficient suction and the scrap on the top surface cannot be cleaned, the fan and the fan inlet valve are closed through the controller, and the vibration motor is started. The mechanical vibration generated by the vibration motor acts on the suction hood filter fixed under the suction hood box, and the strong high-frequency amplitude is used to shake off the debris in the suction hood filter, thereby achieving the purpose of cleaning the suction hood filter.

[0029] Example 2

[0030] Reference Figure 2 This embodiment discloses an automatic cleaning device for the suction hood of an aerated block cutting machine, comprising a suction hood box body 1, a metal grid provided on the bottom surface of the suction hood box body 1, and a suction hood filter 3 fixed outside the metal grid. A suction hood fan 2 is provided on the outer surface of the suction hood box body 1, and the suction hood fan 2 is connected to the suction hood box body 1 through an air intake pipe 2-1. The air intake pipe 2-1 is an inverted U-shaped pipe, and the two ends of the air intake pipe 2-1 are respectively connected to the suction hood box body 1. A fan air intake valve 2-3 is provided on the upper part of the U-shaped pipe, and the suction hood fan air intake pipe 2-1 is connected to the fan inlet valve 2-3. The fan inlet valve 2-3 is connected to the controller. When compressed air is sprayed in, the fan air intake valve 2-3 is automatically closed to prevent the compressed air from being depressurized. The air storage tank outlet pipe 5-3 is connected to the suction hood fan air intake pipe 2-1, and an electromagnetic pulse valve 5-1 is provided on the air storage tank outlet pipe 5-3, and the electromagnetic pulse valve 5-1 is connected to the controller. The air storage tank 5 is provided with an air storage tank air inlet pipe 5-4, and the air storage tank air inlet pipe 5-4 is provided with a valve 5-2 to connect to an external compressed air source.

[0031] When the suction hood filter is clogged with scrap debris, resulting in insufficient suction and the scrap on the top surface cannot be cleaned, the fan and the fan inlet valve are closed by the controller, and the electromagnetic pulse valve is opened instantly. The compressed air stored in the air tank is sprayed into the suction hood box through the connected pipe, and the impact pressure of the compressed air is used to blow away the debris in the suction hood filter from the inside to the outside, thereby achieving the purpose of cleaning the suction hood filter.

[0032] Example 3

[0033] Reference Figure 3 This embodiment discloses an automatic cleaning device for the suction hood of an aerated block cutting machine, comprising a suction hood box body 1, a metal grid provided on the bottom surface of the suction hood box body 1, and a suction hood filter 3 fixed outside the metal grid. A suction hood fan 2 is provided on the outer surface of the suction hood box body 1, and the suction hood fan 2 is connected to the suction hood box body 1 through an air intake pipe 2-1. The air intake pipe 2-1 is an inverted U-shaped pipe, and the two ends of the air intake pipe 2-1 are respectively connected to the suction hood box body 1. A fan air intake valve 2-3 is provided on the upper part of the U-shaped pipe, and the suction hood fan air intake pipe 2-1 is connected to the fan inlet valve 2-3.

Air tank 5 is equipped with an air inlet pipe 5-4, which is equipped with a valve 5-2 for connecting to an external compressed air source. The compressed air stored in air tank 5 is momentarily opened by an electromagnetic pulse valve 5-1 and sprayed into the suction hood housing 1 through the connected air inlet pipe 2-1. The impact pressure of the compressed air blows debris from the suction hood filter 3 from the inside out, thereby cleaning the suction hood filter 3. Two vibration motors 4 are symmetrically mounted on the outer surface of the suction hood housing 1 and connected to a controller. The number of vibration motors 4 is designed based on the size and weight of the suction hood housing 1, as well as the required excitation force. The mechanical vibrations generated by the vibration motors 4 act on the suction hood filter 3 fixed below the suction hood housing 1, with strong, high-frequency amplitude vibrations that dislodge debris from the suction hood filter 3. If the suction hood filter is severely clogged, the controller shuts down the fan and fan inlet valve, starts the vibration motor, and opens the electromagnetic pulse valve at the air tank outlet. This dual cleaning process, using both the vibration motor and compressed air, achieves optimal cleaning results.

[0034] The present invention arranges an air storage tank and a vibration motor on the suction hood housing so that when the suction hood filter is clogged by scraps of waste blanks, resulting in insufficient suction that affects subsequent operations, referring to Example 1 or Example 2, compressed air alone can be used to blow off the debris in the suction hood filter, or a vibration motor alone can be used to shake off the debris in the suction hood filter with a strong high-frequency amplitude. When the suction hood filter is seriously clogged, referring to Example 3, a vibration motor and compressed air are simultaneously used for dual-force and thorough cleaning, so that the suction hood housing is always in the best working state and achieves a better cleaning effect. The present invention has a simple structure, easy maintenance, and high work efficiency, and can clean the suction hood filter online and in real time. At the same time, it communicates with the trolley operation, blank cutting, and mobile positioning, and is automatically controlled by the controller, and is connected in an orderly manner with the production system. It maintains the continuity of production, improves product quality, effectively reduces labor intensity, and has good application prospects.

[0035] The above are only preferred embodiments of the present invention. Any simple modification, deformation and equivalent replacement made by anyone to the present invention based on the content of the present invention shall fall within the scope of protection of the present invention.
