[0002] Cement grinding aid is a chemical additive that improves the grinding effect and performance of cement. It can significantly increase the hourly output of cement, the strength of cement at all ages, and improve its fluidity. Cement grinding aid can greatly reduce the electrostatic adsorption and balling phenomenon formed during the grinding process, and can reduce the re-agglomeration tendency of ultrafine particles formed during the grinding process. Cement grinding aid can also significantly improve cement fluidity, improve the grinding effect of the mill and the powder selection efficiency of the powder classifier, thereby reducing grinding energy consumption. Cement produced using grinding aids has a lower compaction and agglomeration tendency, which is beneficial to the loading and unloading of cement and can reduce the wall hanging phenomenon of cement storage.

[0010] Furthermore, the two fans are vertically fixed to the side of the dust collecting box, and a dustproof net is fixed to the air intake of the fan.

[0011] Furthermore, the filtering accuracy of the filter element close to the fan is greater than that of the filter element far away from the fan, and the gap between the filter elements close to the dust box is greater than the gap between the filter elements far away from the dust box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a plurality of layers of filter elements are arranged inside the dust box, and the air carrying dust is sucked into the dust box through a fan, so that the dust in the air adheres to the surface of the filter element, and then the connecting rod is struck and vibrated by the cylinder, so that the dust on the filter element falls and is discharged and recovered from the dust outlet, thereby solving the problem that a large amount of dust is generated, which not only pollutes the environment but also threatens the health of the operator.

[0014] 2. In the utility model, a number of guide plates are fixed inside the sealing tube, so that the air carrying dust can flow faster.

[0022] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a cement grinding aid production device with dust-proof effect, comprises a production device body 1, a sealing tube 2 is connected to the top of the production device body 1 through a flange, a transmission tube 3 is connected to the top of the sealing tube 2 through a flange, a dust box 4 is arranged on one side of the production device body 1, an end of the transmission tube 3 away from the production device body 1 is connected to the inside of the dust box 4, a dust outlet 5 is fixed to the bottom of the dust box 4, a valve 6 is arranged inside the dust outlet 5, two fans 7 are fixed to the side of the dust box 4 away from the transmission tube 3, the air intake of each fan 7 is connected to the inside of the dust box 4, four connecting rods 8 are symmetrically fixed on both sides of the inside of the dust box 4, a connecting frame 9 is fixed on every two opposite connecting rods 8, a filter element 10 is fixed between every two opposite connecting frames 9, a cylinder 12 is fixed on the top of the production device body 1, an output end of the cylinder 12 extends to the inside of the dust box 4, and the output end of the dust box 4 is located above the connecting rod 8 above the inside of the dust box 4, so that the dust produced by the production of the production device body 1 flows into the inside of the dust box 4 for recovery.

[0024] Specifically, a number of guide plates 13 are fixed at equal intervals on the inner side of the sealing tube 2. The guide plates 13 are triangular in shape to speed up the flow of air. Four fixing rings 11 are symmetrically arranged on both sides of each connecting frame 9. Each fixing ring 11 is fixed on the connecting rod 8, so that the fixing ring 11 assists in fixing the connecting frame 9 on the connecting rod 8. A card slot 15 is provided on the outer side of the dust outlet 5. The card slot 15 is located below the valve 6, so that the staff can conveniently fix the recovery bag on the card slot 15.

[0025] As an optimization solution, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the filtering accuracy of the filter element 10 close to the fan 7 is greater than that of the filter element 10 far away from the fan 7, and the gap between the filter elements 10 close to the dust box 4 is greater than the gap between the filter elements 10 far away from the dust box 4, thereby improving the filtering efficiency of the filter element 10.

[0026] Specifically, two fans 7 are vertically fixed to the side of the dust box 4 , and a dustproof net 14 is fixed to the air intake of the fans 7 to prevent dust from being discharged by the fans 7 .

[0027] Working principle: When the main body 1 of the production device generates dust during operation, the valve 6 is closed and the fan 7 is started, so that negative pressure is formed inside the dust box 4, and the air carrying dust is sucked into the dust box 4 through the sealing tube 2 and the transmission tube 3. When the air carrying dust passes through the sealing tube 2, the guide plate 13 guides the air flow direction, so that the air flow rate is accelerated. When the air carrying dust enters the dust box 4, the air passes through the multi-layer filter element 10 and is discharged by the fan 7. At the same time, the dustproof net 14 prevents the dust carried in the air from being discharged by the fan 7. When the air passes through the filter element 10, the dust in the air adheres to the filter element 10, and at the same time, the dust box 4 The closer the gap between adjacent filter elements 10 inside is to the transmission pipe 3, the larger the gap between adjacent filter elements 10 inside is, and the closer the filter element 10 is to the fan 7, the higher the filtering accuracy is, so that multiple filter elements 10 filter dust step by step. After the dust filtering is completed, the fan 7 is turned off. At this time, the staff will tie the recovery bag to the slot 15, open the valve 6, and then start the cylinder 12, so that the output end of the cylinder 12 hits the connecting rod 8, causing the connecting rod 8 to vibrate. At the same time, the connecting rod 8 drives the connecting frame 9 to vibrate, and the connecting frame 9 drives the filter element 10 to vibrate. The dust on the filter element 10 is vibrated and then separated from the filter element 10, so that the dust naturally falls into the recovery bag through the dust outlet 5.
