Abstract

The utility model relates to a self-gravity cut bag feeding device. A hopper is arranged at the feed port of a pulping tank; a support frame is arranged below the hopper and provided with a bag cutting triangular knife; and the upper part of the bag cutting triangular knife is provided with a spine of a bag opening cutter, and the lower part of the bag cutting triangular knife is provided with a vertical three-blade bag cutting knife. The self-gravity cut bag feeding device can be used for regularly opening the bottoms of ton bags, simultaneously ensuring the safety and the health of operating personnel and further avoiding or reducing choking phenomena, and is convenient to manufacture, and lateral air draft dedusting is not used, so that the power consumption is reduced; and the self-gravity cut bag feeding device can be adopted during magnesium oxide desulfuration for sintering flue gas and flue gas of heat power plants, and can also be adopted in the bottom opening feeding process of cement and loose powder materials filled in long ton bags.

Description

Cut a bag charging device from gravity

Technical field

The utility model belongs to bag discharge device technical field of cutting that the granular material of bagged-powder feeds intake, and what the desulphurization chemical that relates to a kind of sintering, electric power wet desulphurization fed intake that slurrying and the granular material of the bagged-powders such as cement, flour feed intake cuts a bag charging device from gravity.

Background technology

At present, when the desulphurization chemical slurrying of sintering, electric power wet desulphurization, feeding intake is jumbo bag dress powder and granule shape material by overhead traveling crane or loop wheel machine, forklift truck lifting equipment to the hopper that feeds intake, cuts open blowing with billhook by artificial bottom jumbo bag.The desulphurization chemical slurrying of certain steel mill's sintering flue gas of sintering machine feeds intake and adopts the human billhook to cut bag to feed intake, cut bag personnel during discharging and dress dust spectacles, dust cap, coordinate landing with the craneman, finish and cut bag, disclose material, and slurrying feeds intake.Manually cut bag with billhook and seriously fly upward dust to what human body had harm, and operation exists that personnel's is dangerous under the gross ton bag; Manually cut a bag opening and cut to get very irregular, cause the jumbo bag material to flow through and often block, lean on manually again hook, disclose, cause the mixing time that feeds intake oversize.In addition, the hopper side ventilation and dust removal pipeline that feeds intake is large because of dust, and moisture content is greatly also blocked inefficacy often simultaneously, and on-the-spot dust pollution is very large.

The utility model content

The safety and the operating condition that feed intake for the workman improve, avoid the openings of sizes of sack to differ, the long problem of bag clogged with fragments dog-house and charging time, the utility model provide a kind of utilization from the gravity broken bag, need not manually cut bag, quickness and high efficiency, conveniently feed intake cut a bag charging device from gravity.

The technical scheme that its technical matters that solves the utility model adopts is: a kind ofly cut a bag charging device from gravity, at the pulping tank dog-house hopper is housed, have bracing frame at hopper, be equipped with at bracing frame and cut a bag triangular knife, this top of cutting bag triangular knife is out the spine of bag cutter, and its bottom is vertical three and cuts a bag cutter.

The hopper cover that can reduce airborne dust is equipped with in the upper end of described hopper by operating mechanism.

The beneficial effects of the utility model are: can regularly guarantee simultaneously operating personnel's safety and Health rapidly at the jumbo bag bottom opening, also can avoid or reduce latch up phenomenon, the side ventilation and dust removal are stopped using and reduced power consumption, and are easy to make; Can adopt during with the magnesium oxide desulfurization at sinter fume and thermoelectric power station flue gas, again can cement etc. bottom opening during other large jumbo bag dress loose powder material feed intake and adopt in the process.

Among the figure: 1-drives a bag cutter, the 2-hopper, and the 3-bracing frame, vertical three of 4-cuts a bag cutter, the 5-hopper cover.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Referring to Fig. 1 to Fig. 5, a kind ofly cut a bag charging device from gravity, at the pulping tank dog-house hopper 2 is housed, the hopper cover 5 that can reduce airborne dust is equipped with in upper end at hopper 2 by operating mechanism, have bracing frame 3 at hopper 2, be equipped with at bracing frame 3 and cut a bag triangular knife, this top of cutting bag triangular knife is out the spine of bag cutter 1, and its bottom is vertical three and cuts bag cutter 4.When jumbo bag is hung lower time, bag cutter 1 spine and the bag end three of opening that utilize jumbo bag deadweight to cut on bag triangular knife cut bag cutter 4 and cut open the bag bottom, and material is cast pulping tank fast from the jumbo bag bottom, and bag down when the jumbo bag material is cast, can cover hopper cover 5 by mechanism operation, reduce airborne dust.It is very regular to cut bag estuary, can not break away from sack and fall down the material mouthful of resulting in blockage, and perhaps falls into the slurries delivery port that pulping tank is blocked pulping tank, causes carrying slurries, reaches slurrying personal security, the slurrying high effect of efficient that feeds intake.

During actual the use, in the time will feeding intake, open two hopper cover 5 of hopper 2 upper ends of Fig. 5, overhead traveling crane or forklift truck lifting equipment jumbo bag material, jumbo bag is put into hopper, toward transferring, the jumbo bag bottom is opened bag cutter 1 spine and is pierced through among Fig. 1, is to cut vertical three of bagging apparatus from gravity to cut bag cutter 4 and cut open by Fig. 2 down again, vertical three are cut bag cutter 4 and are trigonometric expression, self-gravity action more down scarfing is larger, and it is large that material flow becomes, and feeds intake and just leaks down very soon.Bag is stopping hopper top when feeding intake, and covers hopper cover when material falls, and can reduce dust pollution.

The device that the utility model is hermetically sealed, automatic bag-opening, feed intake, it has not only reduced the employee and has manually opened a bag work capacity, Employee Security problem when also solving well the very serious problem of magnesia powder reentrainment of dust when feeding intake and feeding intake, the charging time of slurrying one tank shortens to 1 hour 25 minutes after transforming, solved reentrainment of dust, and invest littlely, effect is fine.Specifically: the one, improve slurrying efficient about 19%; The 2nd, brownout: stop using dust exhaustor and vibrator are saved electricity consumption; The 3rd, cut bag without manpower with billhook, alleviate personnel labor intensity and work capacity; The 4th, reduce airborne dust, reduce and pollute, improve operating environment

Adopt the utility model, can regularly guarantee simultaneously operating personnel's safety and Health rapidly at the jumbo bag bottom opening, also can avoid or reduce latch up phenomenon, the side ventilation and dust removal are stopped using and reduced power consumption, and are easy to make; Can adopt during with the magnesium oxide desulfurization at sinter fume and thermoelectric power station flue gas, again can cement etc. bottom opening during other large jumbo bag dress loose powder material feed intake and adopt in the process.
