[0002] Aluminum powder paste, also known as aerated aluminum powder and aluminum powder paste for aerated concrete, has a certain earthquake resistance. Aerated aluminum powder has many benefits. For example, aerated concrete produced with aerated aluminum powder has good sound insulation, thermal insulation and earthquake resistance. In the production process of aluminum powder paste, it needs to be ground and crushed first, and the aluminum powder paste may not be crushed thoroughly during the grinding process, so the aluminum powder paste needs to be screened.

[0003] The Chinese utility model patent application number CN202023067787.3 proposes a convenient screening device for aluminum powder paste production that can solve the above problems;

[0004] The equipment uses a screw conveyor rod when filtering (see reference document Figure 1 ) for transportation, and a filter is used at the same time; when the aluminum powder paste is being transported, the aluminum powder will enter the filter for filtration, and the aluminum powder that meets the diameter will pass through the filter, and the non-compliant will be transported away by the auger conveyor rod; however, the diameter of the aluminum powder is very small, which may cause large particles of aluminum powder to be directly spread on the filter, resulting in small particles of aluminum powder cannot be filtered; therefore, the applicant believes that the equipment can still be optimized. Utility Model Content

[0005] The purpose of the utility model is to provide an aluminum powder paste screening device that can effectively solve the above-mentioned problems.

[0008] Furthermore: it also includes a screening box, the feeding cylinder is arranged in the screening box, and the two ends of the sliding rod are fixed to the side surfaces of the box body of the screening box.

[0009] Furthermore: the pushing device includes a push rod, which passes through the screening box and is slidingly connected to the screening box. One end of the push rod is hinged with a connecting rod, and one end of the connecting rod is rotatably connected to a cam. The cam is connected to an electric motor through a transmission shaft.

[0010] Furthermore: the filter screen is arc-shaped, and mounting bars are provided at the front and rear ends of the filter screen, a slide groove is provided in the mounting bar, and the slide rod is slidably provided in the slide groove.

[0011] Furthermore: a collecting hopper is provided in the screening box below the filter screen, a feeding hopper is provided at the upper end of the screening box, and the feeding hopper is provided at the feeding port position.

[0012] Furthermore: the auger conveyor includes a rotating rod and a spiral blade, a driving motor is provided at one end of the rotating rod, and the driving motor is fixed on the outside of the screening box.

[0013] The beneficial effects are:

[0014] The aluminum powder of this device is added into the feeding barrel from the feeding port, and then the driving motor is started to control the rotation of the rotating rod, driving the spiral blade to push the aluminum powder to move. At this time, the aluminum powder will fall from the discharge port onto the filter screen;

[0015] At this time, turn on the pushing device and push the filter to slide back and forth along the slide rod. This can shake the aluminum powder on the filter, prevent the aluminum powder from accumulating on the filter and causing the filter holes to be blocked, and improve the filtering effect of the aluminum powder.

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] See Figure 1-4 This is an embodiment of an aluminum powder paste screening device of the utility model.

[0025] It includes a feeding barrel 1 and an auger conveyor 2 rotatably arranged in the feeding barrel 1; a feeding port 3 is provided at the upper end of the feeding barrel 1, a discharge port 4 is provided at the lower end, and a filter screen 5 is provided at the position of the discharge port 4; wherein, a sliding rod 6 is installed at the front and rear ends of the filter screen 5, and a pushing device 7 is installed on one side of the filter screen 5 to push the filter screen 5 to slide on the sliding rod 6.

[0026] The auger conveyor 2 includes a rotating rod and spiral blades. A driving motor is provided at one end of the rotating rod, and the driving motor is fixed outside the screening box 8.

[0027] The aluminum powder of this device is added to the feeding barrel 1 from the feeding port 3, and then the driving motor is started to control the rotation of the rotating rod, driving the spiral blade to push the aluminum powder to move. At this time, the aluminum powder will fall from the discharge port 4 onto the filter screen 5;

[0028] At this time, the pushing device 7 is turned on to push the filter 5 to slide back and forth along the slide rod 6, which can shake the aluminum powder on the filter 5, thereby preventing the aluminum powder from accumulating on the filter 5 and causing the filter holes to be blocked, and improving the filtering effect of the aluminum powder.

[0029] It also includes a screening box 8, the feeding cylinder 1 is arranged in the screening box 8, and the two ends of the sliding rod 6 are fixed to the side surfaces of the box body of the screening box 8.

[0030] This device is mainly arranged in the screening box 8, through which the feeding cylinder 1 can be fixed, so that the auger conveyor 2 can work conveniently. At the same time, the slide bar 6 can also be fixed on the screening box 8, so that the filter screen 5 can move back and forth conveniently.

[0031] The pushing device 7 includes a push rod 9, which passes through the screening box 8 and is slidably connected to the screening box 8. One end of the push rod 9 is hinged with a connecting rod 10, and one end of the connecting rod 10 is rotatably connected to a cam 11. The cam 11 is connected to a motor 12 through a transmission shaft.

[0032] The pushing device 7 of this device adopts a cam mechanism. Of course, a cylinder or a hydraulic cylinder can also be directly used, but the cam mechanism has stronger stability. The motor 12 of this device is a bidirectional asynchronous motor. When the pushing device 7 is working, the motor 12 is started, driving the cam 11 to rotate, and the cam 11 drives the connecting rod 10 to move. At the same time, due to the limitation of the screening box 8, the connecting rod 10 will drive the push rod 9 to move linearly, thereby realizing the function of reciprocating linear movement of the filter screen 5.

[0033] The filter screen 5 is arc-shaped, and mounting bars 13 are provided at the front and rear ends of the filter screen 5 . A slide groove is provided in the mounting bar 13 , and the slide rod 6 is slidably provided in the slide groove.

[0034] The arc shape better fits the discharge port 4 of the feeding barrel 1; the function of the mounting strip 13 is to facilitate the installation of the slide rod 6.

[0035] A collecting hopper 14 is provided in the screening box 8 below the filter screen 5 , and a feeding hopper 15 is provided at the upper end of the screening box 8 , and the feeding hopper 15 is provided at the feeding port 3 .
