Description

Spacing self-adjusting type grid blade group and grid
Technical Field
The invention relates to the field of water treatment equipment, in particular to a self-adjusting interval type grid blade set and a grid.
Background
The crushing type grid is a garbage crusher arranged at a water inlet of a drainage pump station. The current crushing type grating is generally composed of a left group of rotating blade sets and a right group of rotating blade sets which are arranged in a waterproof frame and a vertical rotary drum which is positioned on the left and the right of the blade sets. After the crushing type grating is started, the motor starts to work to drive the cutting blades in the grating cutting area and the vertical rotary drums in the rotary drum areas on the two sides to simultaneously perform opposite differential rotation. Small-volume sundries in water can enter the next stage through the vertical rotary drum, and if large-volume sundries exist, the sundries can be intercepted by the vertical rotary drum rotating to the crushing area and conveyed to the crushing area for crushing. In the crushing area, sundries are quickly cut and crushed into 6-12 mm fragments in the axial direction and the radial direction by two groups of rotating blades. The crushed sundries do not need to be collected and salvaged and subjected to secondary treatment, but directly enter a subsequent lift pump along with water flow. The crushing type grid is used in the pump station, so that the problem of blockage of the pump can be effectively reduced, and the working efficiency of the pump station is improved.
The gasket and two independent groups of cutting blades of the existing crushing type grating are arranged on two parallel shafts, and the blades are mutually alternated, so that spiral cutting can be performed on sundries. The general cutting blade and gasket all adopt the hexagon, and some brands are hexagonal plum blossom type, install on assorted driving shaft and driven shaft. The blade group consisting of the plurality of blades can thoroughly crush large-particle impurities. The blade is generally made of alloy steel with high strength and uniform surface. The application of the material and the special design of the blade can ensure that the grating can stably and thoroughly cut large-volume sundries with different textures. The solid foreign materials intercepted in the pulverizing type grids can be completely removed as the cutting blades rotate. And the alternate design of the grating cutting blades also enables the grating to self-clean the blade set while crushing sundries, and other cleaning equipment is not required to be additionally arranged. The cutting blade of the crushing type grating adopts a bidirectional rotating design, when a sensor detects that flexible impurities are involved in a crushing area or rigid impurities are clamped into a blade gap, a reverse rotation program is activated, and the blade group can move reversely to release the impurities which block the normal work of the crushing type grating.
However, the distance between adjacent blades of the existing crushing type grating cannot be changed, and once sundries are clamped in, only the blade group is reversed to release the sundries. However, when the blade is reversely rotated, only flexible sundries can be released, and hard sundries clamped into the blade interval cannot be released, if manual cleaning is not performed in time, the hard sundries are likely to cause deformation and damage of the blade in the rotating process of the blade, the service life of the blade is further shortened, and the subsequent crushing effect is also poor.

And repeating the steps until the whole group of blades rotate forwards to enter a normal working state. At this time, no gap exists between the sliding blocks of the two adjacent blades, and the distance between the two adjacent blades is the normal working distance (as shown in fig. 1).
When sundries are clamped in the grating, a control system of the grating activates a reverse rotation program, a limiting driving shaft of a driving device reversely rotates at the moment, a protruding sliding pin at the lower end of a driving sliding block of a driving blade reversely rotates in an inwards concave sliding groove of a driven sliding block of a second blade, and the lower side of the inwards concave sliding groove is an inclined plane, so that the protruding sliding pin can generate axial displacement when reversely sliding, further drives the blades to axially move, the distance between two adjacent blades is increased, and a release gap (shown in figure 2) is formed between the two adjacent blades at the moment; when the protruding sliding pin slides to the tail end of the corresponding concave sliding groove, the second blade is driven to rotate reversely, so that the sliding motion is ended, the interval between the blades is enlarged, sundries are released, and the released sundries can flow out of the grille under the driving of water flow.
Furthermore, in order to prevent sundries from being clamped into the concave sliding groove, a corrugated rubber sleeve can be arranged outside the sliding block of the blade group to protect the concave sliding groove and the convex sliding pin.
The blade set of the invention has at least the following advantages:
the blade gap can be increased when the grating rotates reversely, and impurities can be fully released to enter the next stage or perform secondary cutting. The crushing type grating applying the blade set can reduce the workload of manual maintenance under the condition of prolonging the service life of the blades, and can ensure that the grating can realize more perfect unmanned full-automatic operation.
