detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Referring to Figures 1-3, the utility model discloses a small filter screen equipment, which includes a motor (17), two side plates (1) and three trapezoidal columns (2); the motor (17) is fixed on the shock absorbing on the rubber plate (18); the bottom of the shock-absorbing rubber plate (18) is provided with a base (16); It is connected with the lower fixing rod (13); the upper fixing rod (14) is arranged on the upper part of the two side plates (1), and the lower fixing rod (13) is arranged on the lower part of the two side boards (1); the said The top of the two side plates (1) is provided with a baffle plate (6) on the same level as the side plate (1); the left and right ends of the outer sides of the two side plates (1) are respectively welded with cylindrical bumps (4); The cylindrical bump (4) is locked and connected to the trapezoidal column (2) through the hoop (5); a shock absorbing spring (3) is also provided between the hoop (5) and the trapezoidal column (2); The upper part of the two side plates (1) is provided with a sieve plate (8) perpendicular to it and equal in length; the sieve plate (8) is provided with an oval sieve hole (7); the sieve plate (8) One end is fixed on the upper fixing rod (14); the lower part of the two side plates (1) is provided with an arc-shaped receiving trough (12) of the same length; one end of the arc-shaped receiving trough (12) It is fixed on the lower fixing rod (13), and the other end is fixed on the bottom of the side plate (1); the middle part of one side plate (1) is provided with a bearing (11), and the middle part of the other side plate (1) is provided with a coupling Shaft (15); the bottom of the bearing (11) is connected to the trapezoidal column (2); the transmission shaft (10) of the motor (17) passes through the coupling (15) and the bearing on the other side ( 11) Phase rolling connection; the end of the transmission shaft (10) is fixed with a detachable polarized metal block (9), and polarized metal blocks of different masses and sizes can be replaced as required.

The working principle of the utility model is:

When the motor is running at the same frequency, different vibration frequencies can be obtained by replacing polarized metal blocks of different masses and sizes; when the frequency of the motor is adjusted under the adjustment of polarized metal blocks of the same mass and size, different vibration frequencies can also be obtained. vibration frequency. The process of placing broken materials with different particle sizes on the sieve plate, passing through the sieve surface with evenly distributed holes many times, and dividing them into several different levels is called sieving. The particles larger than the sieve hole stay on the sieve surface, and the particles smaller than the sieve hole fall through the sieve hole to the arc receiving trough for further filtration and sieving. The actual screening process is: after a large number of broken materials with different particle sizes and mixed thicknesses enter the screen surface, only a part of the particles are in contact with the screen surface. The gap between the holes is further enlarged, and the small particles take the opportunity to pass through the gap and transfer to the arc-shaped receiving trough on the lower layer. Due to the small gap between the small particles, the large particles cannot pass through, so the particle groups that were originally arranged in disorder are separated, that is, they are layered according to the particle size, forming an arrangement rule that the small particles are at the bottom and the coarse particles are at the top, and finally realized Coarse and fine particles are separated to complete the screening process.

The utility model is not limited to the above-mentioned best implementation mode, anyone should know that the structural changes made under the enlightenment of the utility model, all technical solutions that are the same as or similar to the utility model, all fall under the protection of the utility model scope.
