[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0022] like Figure 1 and Figure 2 As shown, the utility model is an automatic back-blowing dust removal device for floor dust collection equipment, comprising an air storage tank 1, an air compressor 2, a pulse valve 3, a nozzle 4, a dust collection chamber 6, and a timer 7.

[0023] The main body of the floor dust collection equipment includes a machine body and three rows of filter elements placed in the upper left part of the body; the air tank 1 and the air compressor 2 are arranged on the right side of the filter element, and are separated from the filter element by a baffle. The air compressor 2 is located above the air tank 1, and a partition is provided between them. The air compressor 2 and the air tank 1 are connected by an air pipe. Three nozzles 4 are respectively provided above the three rows of filter elements. The left ends of the nozzles 4 are respectively connected to the pulse valves 3 installed on the outside of the machine body. The pulse valve 3 is connected to the air tank 1 through an air pipe, and the pulse valve interval is controlled by a timer 7. The dust collecting chamber 6 is provided at the bottom of the filter element 5. Its length and width are greater than the length and width of the three rows of filter elements, so that all the dust can be collected.

[0024] like Figure 1 As shown, the automatic back-blowing dust removal device, except for the pulse valve 3, is installed in the dust collecting equipment. Ventilation holes are opened on the sides of the air compressor and the gas tank box. The box where the filter element and the nozzle are located is a sealed chamber, which is sealed by a set door to prevent dust from escaping. When it needs to be opened, just open the door.

[0025] The dust collecting chamber 6 is a mobile cart with pulleys 8 installed around the bottom of the cart. Two quick lock hook clamps 9 are respectively provided on both sides of the long side of the mobile cart. One end of the quick lock hook clamp is installed on the box where the filter element is located, and the other end is installed on the mobile cart, so as to realize the connection between the mobile cart and the box. When working, two people lift the cart upward on both sides at the same time and buckle it through the quick lock hook clamp. The mobile cart is fixed on the upper box for dust collection, and its bottom pulley is in a suspended state, which will not affect the operation of the floor grinder. When cleaning is needed, the quick lock hook clamp is manually opened and buckled, the cart falls, and the cart is manually pushed out to clean the dust inside.

[0026] Specifically, when the floor grinder is working, the dust collection equipment inside it will synchronously collect the dust generated by grinding, and the collected dust will be adsorbed on the filter element. After a period of time, the timer controls the pulse valve 3 to open and the high-pressure gas generated by the air compressor 2 enters the nozzle 4 through the pulse valve 3 from the gas tank 1. The high-pressure gas blows the filter element through the nozzle hole on the nozzle 4, and blows the dust on the filter element into the dust collecting chamber at the bottom of the filter element. When the timer setting time is reached, the dust removal device stops working and will be restarted at the next time, thereby realizing automatic backblowing dust removal.

[0027] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
