Description

Liquid vacuum suction pot for paper making

The utility model relates to the improvement of the liquid attracting device that paper industry uses, and is that liquid vacuum that a kind of paper industry is used attracts jar, is specially adapted to the new equipment of the application on the liquid conveying systems such as the low concentration paper pulp of pulping and paper-making factory and plain boiled water.

At present, the suction device that uses in the delivery system of liquid that uses in the paper industry such as plain boiled water, paper pulp, black liquor, sewage etc. generally adopts suction pipe to add bottom valve, by the direct structure that connects with the pump housing that driven by engine of delivery pipe, bottom valve is equipped with in the sucking hole lower end of suction pipe, water injection pipe is installed on the delivery pipe, be convenient to before the turn on pump clear water be injected in the pump housing and the suction pipe, air is overflowed, guarantee that the pump housing normally starts.Because the bottom valve flap that this structure is used adopts hinge joint or rubber to be connected with valve body more; so the time one is long; rust is dead easily; thereby influence the normal operation of pump; prior reason is no matter the liquid of carrying in the paper industry is that plain boiled water or paper pulp all contain more fiber; causing has the part fiber retention in the flap of bottom valve in the suction process; cause valve body to be not closed completely even complete ineffective consequence; thereby make the pump housing in case shutdown just is difficult to restart work on; run into this situation; have to shut down down the water maintenance, bring very big trouble to the maintainer.Want water filling and the malfunctioning trouble that causes of bottom valve when solving turn on pump, usually the scheme that solves is to dig melt pit, the pump housing is placed reservoir below or side-lower, difficulty, the increasing construction investment of construction had so both been increased, reduced the degree of utilization of factory building again, and the residing position of the pump housing is in low-lying place, moist easily, accumulated water, under these circumstances, often may the be damaged accident of motor of driving pump body running.

The purpose of this utility model is at above-mentioned deficiency, to propose the liquid vacuum attraction jar that a kind of paper industry is used.

Technical solution of the present utility model is that suction pipe communicates with liquid storage tank, delivery pipe connects with the liquid delivery pump that driven by engine, it is characterized in that, adopted the vacuum attraction jar, the vacuum attraction jar is above liquid storage tank, be installed between suction pipe and the liquid delivery pump, the suction pipe upper end connects with the vacuum attraction jar, pass through connection pipe, the water outlet and the liquid delivery pump of vacuum attraction jar connect, and constitute liquid conveying system, and the water injection pipe and the freeing pipe of band valve is housed on the vacuum attraction jar, suction pipe upper end opening part is on vacuum attraction jar top, and the water outlet on the vacuum attraction jar is in its lower sidewall.Principle of work of the present utility model is, the interior formation of vacuum attraction jar vacuum is reached overcome liquid enters the required hoisting depth H generation of vacuum attraction jar through suction pipe from liquid storage tank resistance, liquid is sucked high-order vacuum attraction jar from the reservoir of low level, send into the liquid delivery pump of working by the connection pipe that connects with the vacuum attraction jar again.Concrete service condition is; first before the start; open the water injection pipe on the vacuum attraction jar and the valve of freeing pipe; water filling in the vacuum attraction jar; air is overflowed; liquid level in the vacuum attraction jar rises till the height of suction tube upper end open; close the valve of water injection pipe and freeing pipe subsequently; can carry out work by the start liquid transmission pump, along with liquid constantly is discharged from, the liquid level in the vacuum attraction jar constantly descends; because of no replenish air; spatial volume constantly enlarges in jar, makes the interior vacuum that forms of vacuum attraction jar to enter the vacuum attraction jar after degree of vacuum in the jar reaches the resistance that can make liquid overcome required hoisting depth; liquid in the storage pond can continuously be inhaled in the jar; liquid delivery pump just can continuously be carried liquid like this, after shutting down, will reflux with liquid in the matched delivery pipe of liquid delivery pump; make and attract jar to be full of by liquid again; do not need again water filling, thereby operate much easier when starting shooting next time again.

Advantage of the present utility model is, and is easy to manufacture, installs simply, easy to operate, overcome the deficiency of existing installation, make easy to maintenance, structure become ground rationally, safely, avoided the underground ponding of digging pit to burn out the accident of motor.Adopt the utility model, suction pipe does not use bottom valve, thereby liquid delivery pump is installed than on the liquid storage tank high ground or floor.Make the expense of installation reduce, increased the reliability of equipment simultaneously.The utility model is not only applicable to the paper pulp delivery system of the plain boiled water and the low concentration of paper industry, is applicable to the liquid conveying system of other industries such as water supply and sewage work in the water conservancy construction and chemical industry, light industry simultaneously.
