Drawings

FIG. 1 is a schematic illustration of the internal structure of a shale dewatering shaker with an undersize discharge device.

Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in figure 1, a take discharge device's under sieve mud dehydration shale shaker, including vibrating box 1 with locate a plurality of sieve 2 of vibrating box 1 inboard, every 2 below slopes of sieve are provided with one under sieve and connect flitch 3, connect flitch 3 lower extreme under the sieve to export one side towards vibrating box 1 afterbody, every 2 tops of sieve all are equipped with an inlet pipe 4.

Preferably, a vibration exciter 6 is arranged on the vibration box body 1, and the bottom of the vibration box body 1 is connected with the ground through a compression spring 7. In this embodiment, the vibration exciter 6 drives the screened material to make continuous throwing motion on the screen plate 2, so that the material is easy to loosen and stratify, and the water penetrates through the screen plate when the material meets the screen plate 2, thereby realizing the dehydration process of the material.

Preferably, the sieve plate 2 is an L-shaped plate structure, and the bottom surface of the sieve plate is inclined. Can prevent after the design like this that the material from 2 lateral parts of sieve from unrestrained, as shown in figure 1, sieve 2 front and back sides in this embodiment and the 1 inside wall fixed connection of vibration box, because sieve 2 is L type plate structure, so 2 right sides of sieve are the baffle structure, and the left side is the feed end, and when sieve 2 was the tilt state, the material can not be unrestrained from the feed end, and the baffle also played the limiting displacement to the material.

Preferably, the lower end of the undersize material receiving plate 3 is fixedly connected with the undersize material discharging plate 8, and the undersize material receiving plate 3 and the undersize material discharging plate 8 shield the sieve plate 2 below. Connect flitch 3 and the cooperation that blocks of arranging flitch 8 under the sieve through the sieve for the muddy water that sees through sieve 2 can flow into 1 afterbody export one side of vibrating box along receiving flitch 3 under the sieve and arranging between flitch 8 under the sieve, and can not enter into lower floor sieve 2, just so can not influence walking speed and the moisture content of lower floor's material.

Preferably, every inlet pipe 4 surface all the suit is fixed with the polylith and scrapes flitch 5, scrape flitch 5 bottom and sieve 2 upper surface contact, inlet pipe 4 and a plurality of vertical discharging pipe 9 intercommunication set up vertical discharging pipe 9 between per two scraping flitchs 5. After the design, the following beneficial effects exist: firstly, the feeding pipe 4 can be limited on the surface of the sieve plate 2 through a plurality of scraping plates 5, and at the moment, the feeding pipe 4 and the scraping plates 5 are combined to form a structure similar to a support frame body and can be directly placed on the surface of the sieve plate 2 without toppling; secondly, a vertical discharge pipe 9 is arranged between every two scraping plates 5, so that the amount of slurry treated on the surface of the sieve plate 2 between every two scraping plates 5 is consistent, and the sieving and dewatering effect is improved; and finally, after the screening and dewatering process is finished, each scraping plate 5 can scrape sludge in a corresponding area respectively, the whole is broken into parts, and the scraping effect is improved.

Preferably, the end of said feed pipe 4 is connected to the bottom liquid outlet pipe of the cyclone by means of a flexible hose 10. After the design like this, after accomplishing screening dehydration process, can directly pull out inlet pipe 4 to alright scrape flitch 5 with pulling out, can scrape out the mud on 2 surfaces of sieve through scraping flitch 5 like this, the design of scalable hose 10 can make inlet pipe 4 freely pull out and put into, and the bellows structure can be chooseed for use to scalable hose 10 in this embodiment in addition.

The working principle of the embodiment is as follows:

firstly, materials discharged from a bottom liquid outlet pipe of the cyclone are respectively pumped into each feeding pipe 4 and then are pumped to the surface of the corresponding sieve plate 2, the vibration exciter 6 is started, the vibration exciter 6 drives the screened materials to do continuous throwing motion on the sieve plate 2, so that the materials are easy to loosen and stratify, and the materials collide when meeting the sieve plate 2 to ensure that moisture penetrates through the sieve, thereby realizing the dehydration process of the materials; after the screening dehydration process is finished, the feeding pipe 4 can be directly pulled out, so that the scraping plate 5 can be pulled out, and the sludge on the surface of the sieve plate 2 can be scraped out through the scraping plate 5; and the muddy water that sees through sieve 2 can connect flitch 3 and sieve down to flow into vibrating box 1 afterbody export one side between the row material board 8 along the sieve, and can not enter into next floor sieve 2, just so can not influence the walking speed and the moisture content of lower floor's material, muddy water finally through vibrating box 1 afterbody export one side and discharge to next process.

The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope.
