specific Embodiment 1

[0025] This embodiment is an embodiment of the mesh width continuously adjustable filter screen.

[0026] The grid width of the present embodiment continuously adjusts the filter screen, and the structural diagram is as follows figure 1 shown. The grid width continuously adjustable filter screen includes a first one-dimensional filter screen 11 and a second one-dimensional filter screen 12 with the same direction, the same cycle, and a duty cycle of 50% that are arranged close to each other up and down. The filter screen 11 and the second one-dimensional filter screen 12 move in reverse under the regulation 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;

[0027] The first one-dimensional filter screen 11 is installed between two first brackets 13 through a linear bearing, and the two first brackets 13 are symmetrically installed on the base 4, and the linear beari...

specific Embodiment 2

[0030] This embodiment is an embodiment of the mesh width continuously adjustable filter screen.

[0031] The mesh width continuous adjustment filter screen of the present embodiment is further defined on the basis of the specific embodiment one:

[0032] 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;

[0033] 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 the bearing. connect.

specific Embodiment 3

[0034] This embodiment is an embodiment of the mesh width continuously adjustable filter screen.

[0035] The grid width of the present embodiment continuously adjusts the filter screen, and the structural diagram is as follows figure 2 shown. On the basis of the specific embodiment 1 or the specific embodiment 2, the mesh width continuously adjusting filter screen is further defined as follows: a storage box 5 is also arranged under the second one-dimensional filter screen 12 .

[0036] This structural limitation can ensure that the things filtered out from the first one-dimensional filter screen 11 and the second one-dimensional filter screen 12 are directly taken away.

Abstract

The invention discloses a grid width continuous adjusting filter net and a grid width continuous adjusting method and belongs to the field of machinery and precision instruments. The grid width continuous adjusting filter net comprises a first one-dimensional filter net and a second one-dimensional filter net which are arranged in an up-down clinging manner, are identical in direction and period and are 50% in duty ratio, the first one-dimensional filter net and the second one-dimensional filter net are adjusted by a filter net adjusting mechanism to move in opposite directions, and the filter net adjusting mechanism is powered by a power transmission device mounted on a base. The grid width continuous adjusting method includes that rotation of a motor in the power transmission device is controlled to drive a transmission rod to rotate so as to drive a rotating body to rotate, and an extending end on the rotating body drives the first one-dimensional filter net and the second one-dimensional filter net to move in opposite directions to realize continuous adjusting of grid width. Due to the structure, the motor can be controlled to rotate at any time according to needs to enable the first one-dimensional filter net and the second one-dimensional filter net to continuously move in opposite directions so as to realize continuous realtime adjusting of grid width.

Description

technical field [0001] The invention discloses a mesh width continuously adjusting filter screen and a mesh width continuously 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 invention discloses a mesh width continuous adjustment filter screen and a mesh width continuous adjustment method, which can realize continuous adjustment of mesh size. [0005] A mesh wi...
