Problems solved by technology

[0005] This patent only sets up a single screen, which can only realize sand screening work of two specifications; Shaft, the second connecting rod, the slider and the second pin make the screen reciprocate up and down, but this structure produces a large range of movement, which is likely to cause the sand to pass through the screen before it can pass through the screen, that is, from the bar on the right. Slot discharge

Embodiment 1

[0055] Reference attached figure 1 , 2 , a graded sand screening treatment device for water conservancy and municipal engineering, comprising a frame assembly 1, a drive assembly 2, a secondary sand screening assembly 3, a transmission assembly 4, and a primary sand screening assembly 5;

[0056] The frame assembly 1 includes a base 101, a column 102 and a pole 103. The base 101 is connected with columns 102 at intervals, and the first-stage sand screening assembly 5 is connected between the columns 102 through the pole 103; The primary sand screening assembly 3; the base 101 is provided with a driving assembly 2, and the driving assembly 2 cooperates with the secondary sand screening assembly 3; the driving assembly 2 is also connected with the primary sand screening assembly 5 through the transmission assembly 4.

Embodiment 2

[0058] Reference attached figure 1 , 2 , a graded sand screening treatment device for water conservancy and municipal engineering, comprising a frame assembly 1, a drive assembly 2, a secondary sand screening assembly 3, a transmission assembly 4, and a primary sand screening assembly 5;

[0059] The frame assembly 1 includes a base 101, a column 102 and a pole 103. The base 101 is provided with columns 102 at intervals, and the columns 102 are connected with a first-stage sand screening assembly 5 through the pole 103; The primary sand screening assembly 3; the base 101 is provided with a driving assembly 2, and the driving assembly 2 cooperates with the secondary sand screening assembly 3; the driving assembly 2 is also connected to the primary sand screening assembly 5 through the transmission assembly 4.

[0060] Wherein, the drive assembly 2 includes a servo motor 201, a drive shaft 202, a cam 203 and a drive wheel 204;

[0061] The servomotor 201 is fixed on the base 1...

Embodiment 3

[0075] On the basis of the above examples,

[0076] See attached image 3 , also includes a vibrating material assembly 6; the vibrating material assembly 6 includes a rack 601, a driven gear 602, a swing rod 603 and a vibrating material head 604;

[0077] One side of the bottom end of the end plate 306 is connected with a horizontal rack 601, and the rack 601 is matched with a driven gear 602, and the driven gear 602 is installed on the column 102; one end of the swing rod 603 is coaxially connected with the driven gear 602, and the other end Stretch below the sand screening frame 301 and be equipped with a vibrating material head 604.

[0078] Specifically, the sand screening frame 301 also moves the end plate 306 through the moving rod 303, so that the rack 601 also reciprocates synchronously, so that the rack 601 drives the driven gear 602 to produce a reciprocating deflection, and the vibrating head 604 Intermittently collides with the secondary screen 302, causing the ...

Abstract

The invention relates to the technical field of sand screening equipment, in particular to a stagewise and screening treatment device and method for water conservancy municipal engineering. The device adopts the design of two stages of screens; a driving shaft rotates through a servo motor; on one hand, the driving shaft drives a driving wheel to rotate, a driven wheel drives a driven part to rotate through a transmission belt, and then a first bevel gear rotates and drives a second bevel gear to drive a mounting shaft in a sand screening box to rotate, so that a stirring rod drives a scraper to stir sand, and the screening of the first-stage screen is accelerated; and on the other hand, sand materials subjected to primary screening fall into a sand screening frame, the driving shaft enables a cam to act on the sand screening frame, and a reset spring is matched, so that the sand screening frame reciprocates, screening of the two-stage screen is accelerated, and therefore, quick stagewise screening of the sand materials is realized.

Description

technical field [0001] The invention relates to the technical field of sand screening equipment, and relates to a graded sand screening treatment device and method for water conservancy and municipal engineering. Background technique [0002] Municipal and water conservancy also belong to the national infrastructure construction, and the construction procedures are basically the same. [0003] Municipal administration mainly refers to urban infrastructure construction, and water conservancy mainly refers to river channel management, water storage, water supply, irrigation, flood control, power generation or comprehensive utilization projects. [0004] The Chinese utility model patent with the patent number CN202021996036.7 discloses a sand screening device for construction engineering, including a sand screening box shell, a sand storage mechanism is fixedly installed on the top of the sand screening box shell, and the left and right sides of the sand screening box shell Tw...
