specific Embodiment 1

[0028] This embodiment is an embodiment of the mesh width continuously adjustable filter screen with vibration function.

[0029] The mesh width continuously adjustable filter screen with vibration function in this embodiment, the structural diagram is as follows figure 1 shown. The grid width continuously adjusting filter screen with vibrating function includes a first one-dimensional filter screen 11 and a second one-dimensional filter screen 12 with the same cycle set up and down, and a duty cycle of 50%. The net 11 and the second one-dimensional filter screen 12 perform reverse motion and vibrate up and down simultaneously under the adjustment of the filter screen adjustment mechanism 2, and the filter screen adjustment mechanism 2 is powered by the power transmission device 3 installed on the base 4;

[0030] The first one-dimensional filter screen 11 is installed between two first supports 13 through a linear bearing, and the linear bearing can ensure that the first one...

specific Embodiment 2

[0033] This embodiment is an embodiment of the mesh width continuously adjustable filter screen with vibration function.

[0034] The mesh width continuous adjustment filter screen with vibration function of this embodiment is further defined on the basis of specific embodiment one:

[0035] The swivel 21 is supported by a swivel bracket 24 installed on the base 4. The specific structure is: the bearing connection between the swivel 21 and the swivel bracket 24, the swivel 21 is interference fit with the inner ring of the bearing, and the swivel bracket 24 is connected to the bearing. The outer ring is fixedly connected;

[0036] The transmission rod 32 is supported by the transmission bracket 33 installed on the base 4. The specific structure is: the bearing connection between the transmission rod 32 and the transmission bracket 33, the transmission rod 32 and the inner ring of the bearing have an interference fit, and the transmission bracket 33 is fixed to the outer ring of...

specific Embodiment 3

[0037] This embodiment is an embodiment of the mesh width continuously adjustable filter screen with vibration function.

[0038] The mesh width continuous adjustment filter screen with vibration function of this embodiment is further defined on the basis of the specific embodiment one: the bottoms of the first support 13 and the second support 14 are all provided with rollers, the first support 13 and the second support Rolling friction is formed between the two brackets 14 and the cam 34 .

[0039] This structural limitation can reduce wear between the first bracket 13 and the second bracket 14 and the cam 34 , thereby improving the service life.

Abstract

The invention provides a grid width continuous adjustment filter screen with vibration function and a continuous adjustment method, and belongs to the fields of machinery and precision instruments. The filter screen comprises a first one-dimensional filter screen and a second one-dimensional filter screen, which are arranged in an upper and lower mode, and have the same cycle and duty ratio 50%; the first one-dimensional filter screen and second one-dimensional filter screen under the regulation of a filter screen regulating mechanism conduct reverse movement and upper and lower vibration at the same time; the screen regulating mechanism is powered by a power transfer device installed on a base. The grid width continuous adjustment method with vibration function controls motor transmission in the power in the power transfer device to drive the upper and lower movement and reverse movement of the first one-dimensional filter screen and second one-dimensional filter screen, so as to realize the continuous adjustment of the mesh width and vibration. The structure of the invention not only can achieve real-time model of grid width, but also can enhance the filtering effect through the vibration of the first one-dimensional filter screen and the second one-dimensional filter screen.

Description

technical field [0001] The invention discloses a mesh width continuously adjusting filter screen with a vibration function and a continuous adjusting method, which belong to the field of machinery and precision instruments. Background technique [0002] The filter screen is referred to as the filter screen, which mainly plays the role of filtering and increasing resistance. It is widely used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries. [0003] However, the mesh size of most of the filter screens is custom-made. If the mesh size can be changed according to needs, the filter screen will play a greater role. Unfortunately, no filters that can adjust the mesh size have been found yet. Contents of the invention [0004] In view of the above problems, the present invention discloses a mesh width continuously adjustable filter screen with vibration function and a continuous adjustment method, which can not only realize continuous...
