Abstract

The utility model relates to a sludge removal device used for a vertical type settling tank, in particular to a built-in type mud scrapping and sucking machine which has the technical proposal that a central bearing, a rotation central body, a mud scraping and sucking arm and a mud drainage pipe are included; the central bearing is hollow structured and is communicated with the mud drainage pipe, the bottom part of the central bearing can be fixedly connected with the settling tank, a horizontal bearing is arranged on the central bearing, the rotation central body comprises a worm wheel, a transmission shaft and a transmission shaft bracket, the transmission shaft is connected with a transmission device, a plurality of mud suction holes and mud scraping plates which are matched with the mud suction holes are arranged on the scraping and suction dredging arm, a dredging pipe is arranged at the outside of a tank body, and a butterfly valve is arranged at the outlet of the dredging pipe; wherein, a tension chain is arranged between the mud scraping and sucking arm and the horizontal bearing. The sludge removal device has the advantages that the sludge removal dead zone of the vertical type settling tank can be eliminated and the sludge in the tank can be automatically cleaned under normal operation conditions of the oil tank.

Description

Built-in scraping and sucking machine

One, technical field:

The utility model relates to a kind of vertical settling tank and removes the mud device, specifically is a kind of built-in scraping and sucking machine.

Two, background technology:

At present, the bottom is provided with fixedly tubular type mud discharging mouth in the vertical settling tank that use in the oil field, but vertical settling tank volume is comparatively huge, in actual motion, fixedly the gravity discharge pipeline can not clear the deposition of jar interior mud-sinking area timely and effectively, along with mud increases in the accumulation of mud-sinking area, the time of staying that makes jar include dirt water shortens, and influence contains the separating effect of dirt water.And the method for removing at present heavy mud is labor cleaning's mud, because the tank body hand-hole is little, and jar inner structure complexity, cleaning work is inconvenience very, the big and poor stability of labour intensity, cleaning cycle is long and cost is high simultaneously.

Three, summary of the invention:

The purpose of this utility model is exactly the defective that exists at prior art, a kind of security performance height is provided, can removes the built-in scraping and sucking machine of jar interior mud automatically.

Its technical scheme is: it comprises centre bearing, the pivot body, scrape and inhale mud arm and discharge pipeline, centre bearing is hollow structure and inhales the mud arm and discharge pipeline is communicated with scraping, can fixedly connected with at the bottom of the jar in its bottom, centre bearing is provided with horizontal support, the pivot body is by worm gear, power transmission shaft and power transmission shaft carriage are formed, power transmission shaft connects transmission device, scrape and inhale the cleaning shoe that the mud arm is provided with a plurality of suction mud mouths and matches with suction mud mouth, discharge pipeline is communicated to the tank body outside, the exit of discharge pipeline is provided with butterfly valve, wherein, scrape to inhale between mud arm and the horizontal support and be provided with the tension chain.

Effect of the present utility model is: can eliminate the spoil disposal dead band in the vertical sedimentation desilt oil tank, under the situation of the normal operation of maintenance oil tank, realization jar interior mud is removed automatically.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is vertical views of the present utility model.

Five, the specific embodiment:

With reference to attached Fig. 1 and 2, the utility model comprises centre bearing 1, pivot body 2, scrape and inhale mud arm 3 and discharge pipeline 4, centre bearing 1 is inhaled mud arm 3 and discharge pipeline 4 is communicated with for hollow structure and with scraping, can fixedly connected with at the bottom of the jar in its bottom, centre bearing 1 is provided with horizontal support 5, pivot body 2 is by worm gear 6, power transmission shaft 7 and power transmission shaft 8 carriages are formed, power transmission shaft 7 connects transmission device 9, scrape and inhale the cleaning shoe 11 that mud arm 3 is provided with a plurality of suction mud mouths 10 and matches with suction mud mouth 10, discharge pipeline 4 is communicated to the tank body outside, the exit of discharge pipeline 4 is provided with butterfly valve 12, wherein, scrapes to inhale to be provided with between mud arm and the horizontal support and strains chain 13.

During use, opened butterfly valve 12 starts transmission device 9, and pivot body 2 drives to scrape inhales mud arm 3 rotation at the bottom of jar, and cleaning shoe 11 stirs a jar end mud, and according to siphon principle, the mud that is stirred enters inhales mud mouth 10, through discharge pipeline 4 discharges, finishes the spoil disposal process then.

Claims
