Abstract

The utility model provides a portable high efficiency vibration sieve. The portable high efficiency vibration sieve is mainly characterized in that two vibrating motors are installed on a sieve frame; the upper spring of a group spring for supporting the sieve frame is connected with a vibration component; a lower spring is connected with a machine frame. Movable sealing structure is used in the sieve frame; folding wheels are installed on the feet of the machine frame. Compared with the existing vibration sieve, the utility model has the advantages of small total weight, low cost, electric energy saving, high efficiency, little pollution, convenient portability and environmental protection, being widely adapted to chemical industry, metallurgy, construction material, minerals, food and wet method sieving.

Description

Portable efficiency vibration sieve

The utility model belongs to screening plant, relates to a kind of portable and effective vibratory sieve.

Existing vibratory sieve mainly contains reciprocating oscillating screen, flat vibrating screen, drum screen etc.The reciprocating oscillating screen vibration number is less, and rotary screen screen cloth and material contact-making surface are little, adds that reciprocating oscillating screen, rotary screen all are back and forth translation or rollings of screen cloth itself, and mesh is blocked easily, so their screening efficiencies are low.The screen frame of reciprocating oscillating screen, flat vibrating screen does not seal, and dust pollution is serious when the dry screening material.A common feature of existing all vibratory sieves is that a vibrating motor is installed on the frame under the screen frame, not only big to the frame vibrations, must fix on the basis, and because of vibrating motor directly ginseng shake, power consumption is also big, the motor that needs is also big, parts are many in addition, therefore equipment is heavy, and noise is big, moves inconvenience.It is also inconvenient that the screen cloth of these vibratory sieves is changed dismounting, maintenance difficult, and influence is produced.In a word, it is low that existing vibratory sieve exists screening efficiency, and power consumption is high, pollutes greatly, and heavy inconvenience is moved, shortcoming such as during the consumable accessory replacement cost.

The purpose of this utility model be development a kind of efficient, energy-conservation, light, pollute little novel vibrating screen.

The main technical schemes that realizes above-mentioned task is: the exciting parts adopt two vibrating motors, are installed on the screen frame; Join the parts that shake and supported by four groups of springs, screen bed base is set in the screen frame, screen frame adopts enclosed construction, and the charging aperture base plate is convex; Device folding wheel on the frame pin.

Further describe specific structural features of the present utility model in conjunction with example and accompanying drawing.

Accompanying drawing is represented the general structure schematic diagram of the utility model portable and effective vibratory sieve.

Referring to accompanying drawing, the utility model portable and effective vibrosieve exciting parts, ginseng shake parts and frame three parts.The main involving vibrations motor 1 of exciting part, vibrating motor 2, vibrating motor seat 3, elevating lever 4.The ginseng part of shaking mainly comprises 9, one of screen frames with upper screen cloth 11, and one deck is with scalping shoe 8, four groups of groups of springs 5, charging aperture 6 and a plurality of discharging opening 13,14.Every group of groups of springs 5, the upper spring in its spring seat of honour are to join the spring that shakes, and link with the exciting parts, and the lower spring in its spring lower seat is an isolation spring, links with frame, and the centre separates by in the spring.Seat is fixed on the screen frame 9 in the spring, plays a supportive role.Rack section mainly comprises frame 10, folding wheel 12.

Exciting source is produced jointly by the motor and the weight of vibrating motor 1,2.Regulate the space angle of vibrating motor weight, can change amplitude, promptly change the curve shape and the flow trace of compass screen surface material movement.Since be equipped with two vibrating motors 1,2,, the running of No. 2 motors makes the compass screen surface material produce conical surface vibration, the running of No. 1 motor makes the compass screen surface material produce rotary vibration, the synergy of two vibrating motors, make on the compass screen surface material do about, double vibrations, vibration number increases, screening thoroughly rapidly.Because vibrating motor is contained on the screen frame, exciting source is near and disembark frame and ground are far away from the ginseng parts that shake, therefore power consumption is little, ginseng is shaken and is provided with isolation spring between parts and frame again in addition, therefore also little to frame, earth shock, so the power of motor can reduce, frame also can be fixed on the basis.Because the base plate of charging aperture 6 is convex, material can be scattering on the screen cloth at the very start equably, avoids the feed end of screen cloth the clear area to occur.In a word, because the resultant effect of above-mentioned measure can fully improve screening efficiency, saves energy can alleviate the screen(ing) machine gross weight again, reduces noise.

Because screen frame 9 tops are provided with cover plate 15, are lined with sealing gasket between cover plate and screen frame, two ends of screen frame 9 are provided with closing door 7, establish the screen frame (unit) 8 more than one deck on the inwall of screen frame 9, and screen cloth 11 is pressed on the screen frame (unit) 8.So not only reduced dust pollution, and when maintenance or cleaning screen cloth, opened closing door and just can change dismounting soon.

Because this vibratory sieve does not need the basis fixing, on frame 10 pin, respectively adorn a folding wheel.During screening operation folding wheel is turned up, when needing mobile machine the folding wheel is put down, just can promote vibratory sieve other places material to be sieved nearby soon, alleviated labour intensity.

This Portable efficiency vibration sieve of the present utility model is compared with existing vibratory sieve, have in light weight, energy-conservation, the efficient height, cost is low, pollute little, advantage and the remarkable results such as conveniently moving. Such as I type vibratory sieve of the present utility model, adopt the 1.5KW vibrating motor, 400 kilograms of gross weights, screening efficiency are 10 tons/hour in quartz sand 20 orders, 2.8 square metres of floor spaces, noise 75-80 decibel, 7350 yuan/platform of cost; And/the 900mm rotary screen, gross weight is 1300 kilograms, adopt 5.5KW vibrating motor, screening efficiency be quartz sand 20 order 8-10 tons/hour, 5.5 square metres of floor spaces, noise 100-110 decibel, 17000 yuan/platform of cost, 1000 yuan of foundation costs. Such as II type vibratory sieve of the present utility model, adopt the 0.2KW vibrating motor, 180 kilograms of gross weights, screening efficiency are 2600 kilograms/hour in 40 order polyvinyl chloride resin powder, 1.2 square metres of floor spaces, noise 65-70 decibel, 4350 yuan/platform of cost; And the double vibrations motor is 3.2KW, and 600 kilograms of gross weights, screening efficiency are 2000 kilograms/hour in 40 order polyvinyl chloride resin powder, 3 square metres of floor spaces, and noise 90-100 decibel, 6500 yuan/platform of cost, 600 yuan of foundation costs, dust pollution is serious.

The utility model vibratory sieve is widely used in the industries such as chemical industry, metallurgy, building materials, mineral products, food, environmental protection and carries out dry method, wet screening.
