Description
Technical field
The utility model relates to a kind of sizing screening equipment, relates in particular to a kind of screening plant in the sizing screening equipment.
Background technology
Feed, food, chemical industry, medicine and other fields are often used the sizing screening equipment that material is divided into the thickness grade, and screening plant is made up of support, frame, drive unit, sieve nest and afterbody supporting mechanism.Sieve nest of the prior art comprises sieve ship, top cover, wooden screen frame down, wooden interval box and the wooden screen frame of going up.The sieve ship is the carrier of screen frame, interval box and top cover, and its base plate is again the discharging opening of material.Top cover covers on the sieve ship, flour dust overflow when preventing to sieve.Screen cloth divides upper and lower two-layer, and respectively on the upper surface by fourth nail screen frame and the wooden screen frame down on wooden of riding, mesh support screen is also followed closely respectively on the lower surface of screen frame and wooden screen frame down on wooden by the fourth of riding, and is provided with elastic ball between screen cloth and the mesh support screen.During installation, place wooden screen frame down in the sieve ship earlier, press wooden interval box then, place the wooden screen frame of going up again, push down all frame fixation with top cover at last.
During work, drive unit drives the sieve nest that constant slope is arranged and does the reciprocating rotating motion, material on the screen cloth is carried out screen, screen cloth is constantly beated, hit to the elastic ball of screen cloth below, prevent that material from stopping up sieve aperture, the screenings of upper screen cloth is fallen and is continued screen on the lower screen cloth, makes that material is divided into slightly, thin grade.
There are the following problems for existing sieve nest:
1, screen frame is a wooden structure, though through qualitative processing, still have certain deformation, especially easily beats after replacing in the use.
2, screen cloth is fixed on the screen frame with staple, changes difficulty, during the nail staple, damages the steel wire of screen cloth easily.
3, after wooden screen frame made moist distortion, the squeezing screen ship was difficult for taking out, and needs the several people just can carry away, and replacing is inconvenient, and damages easily in the taking-up process.
The utility model content
For overcoming the technical problem that exists in the prior art, the utility model provides a kind of screening plant, and is not only light and handy, and screen cloth is changed quick and easy, reliable.
For solving above technical problem, a kind of screening plant provided by the utility model, comprise support, frame, drive unit and sieve nest, sieve nest comprises sieve ship and top cover, the sieve ship in from top to bottom closed assembly two-layer light metal screen frame is arranged, be connected with a plurality of elastic metallic hooks respectively around the two light metal screen frames, two-layer up and down screen cloth is tightened on the upper surface of two light metal screen frames by the elastic metallic hook respectively.
With respect to prior art, the utility model has been obtained following beneficial effect: the direct closed assembly of two-layer light metal screen frame in the sieve ship, cancelled interval box, alleviated complete machine weight, as long as pull up each elastic metallic hook when changing screen cloth, convenient, fast, screen cloth not damaged have improved production efficiency, have reduced use cost; But metal screen frame integral solder forms, and intensity and toughness is reliable, not fragile distortion.
As improvement of the present utility model, the lower surface of two light metal screen frames and top cover is respectively equipped with the type groove, is embedded with rubber weather strip in the various groove respectively.Rubber weather strip is inlaid on the lower surface of screen frame and top cover in advance, compresses step by step during installation, can realize sealing.
Description of drawings
Fig. 1 is the structural representation of the utility model screening plant.
Fig. 2 is the enlarged drawing at A position among Fig. 1.
Among the figure: screen frame supporting screening plate under screen frame sealing strip, 8a upper screen cloth, 8b lower screen cloth, 9a upper screen cloth elastic metallic hook, 9b lower screen cloth elastic metallic hook, the last screen frame supporting screening plate of 10a, the 10b under screen frame, 6 light metal top covers, 7a top seal bar, the last screen frame sealing strip of 7b, the 7c on screen frame, 5 light metals under 1 support, 2 drive units, 3 sieve ships, 4 light metals.
The specific embodiment
As shown in Figures 1 and 2, screening plant of the present utility model comprises support 1, frame, drive unit 2 and sieve nest, and sieve nest comprises sieve ship 3 and light metal top cover 6, and the lower surface of light metal top cover 6 is provided with ring-type type groove, is embedded with top seal bar 7a in the type groove.
In the sieve ship from top to bottom successively closed assembly screen frame 4 under the screen frame 5 and light metal is arranged on the light metal.On the light metal screen frame 5 around be connected with a plurality of upper screen cloth elastic metallic hook 9a, upper screen cloth 8a is tightened in the upper surface of screen frame 5 on the light metal by upper screen cloth elastic metallic hook 9a, the last screen frame supporting screening plate 10a of punching be positioned at upper screen cloth 8a below and with light metal on screen frame 5 be welded as a whole, place elastic ball between last screen frame supporting screening plate 10a and the upper screen cloth 8a.The lower surface of screen frame 5 is provided with ring-type type groove on the light metal, is embedded with top sieve frame sealing strip 7b in the type groove.
Under the light metal screen frame 4 around be connected with a plurality of lower screen cloth elastic metallic hook 9b, lower screen cloth 8b is tightened in the upper surface of screen frame 4 under the light metal by lower screen cloth elastic metallic hook 9b, the following screen frame supporting screening plate 10b of punching be positioned at lower screen cloth 8b below and with light metal under screen frame 4 be welded as a whole, place elastic ball between following screen frame supporting screening plate 10b and the lower screen cloth 8b.The lower surface of screen frame 4 is provided with ring-type type groove under the light metal, is embedded with down screen frame sealing strip 7c in the type groove.
During installation, screen frame 4 under the light metal of screen frame sealing strip 7c under placement is embedded with in sieve ship 3 earlier, place screen frame 5 on the light metal that is embedded with screen frame sealing strip 7b again, cover the light metal top cover 6 that is embedded with top seal bar 7a then, compress with handle at last.When changing screen cloth, open light metal top cover 6, successively screen frame under screen frame on the light metal 5 and the light metal 4 is taken out, pull up upper screen cloth elastic metallic hook 9a and lower screen cloth elastic metallic hook 9b respectively, behind the screen cloth that more renews, put into sieve ship 3 more in order and get final product.
