Abstract

The utility model relates to a petroleum dry cleaner for multi-stage filtering detergent, which is provided with a washing barrel, an oil tank, a fine filter and a detergent circulation line. The oil tank is arranged below a detergent barrel, and the detergent barrel is connected with the oil tank by an oil return pipe; a primary filter is arranged on the point of the connection opening of the oil return pipe in the oil tank, and a cavity body of a secondary filter is also arranged in the oil tank. A final stage fine filter is arranged on the side part of the washing barrel, an oil suction pipe is connected between the cavity body of the secondary filter and the fine filter through an oil suction pump, and an oil supply pipe is connected between the fine filter and the washing barrel. The utility model has the advantages that the utility model is filtered by three stages to cause washing effect to be better, the service life of a fine filter core can be prolonged, and work efficiency can also be improved.

Description

The petroleum dry-washer of multistage filtering washing agent

It is the dry cleaner of washing agent, the particularly petroleum dry-washer of multistage filtering washing agent with the oil that the utility model relates to a kind of.

Big in order to overcome by the intrinsic complex structure of the dry cleaner of washing agent, power consumption with the tetrachloro-ethylene, environment had shortcoming such as pollution, released the petroleum dry-washer of various structures at present both at home and abroad.But petroleum dry-washer of the prior art all has a common weak point: the filtration system of washing agent is too simple, causes fine filter cartridge too short service life; Need often to shut down cleaning thereby influence operating efficiency; Filter not thorough thereby undesirable to the clean result of some clothings.

The utility model purpose is: overcome the deficiency of prior art, a kind of petroleum dry-washer of multistage filtering washing agent is provided.

The utility model is achieved in that the petroleum dry-washer of multistage filtering washing agent, has washtub, fuel tank, fine filter and washing agent circulation line, it is characterized in that: fuel tank is set below washtub, there is oil return pipe to connect between them, primary filter is equipped with at oil return pipe connector place in fuel tank, also be provided with intermediate filter cavity in the fuel tank, be provided with the final stage fine filter at the washtub sidepiece, between intermediate filter cavity and fine filter, be connected a fuel sucking pipe by oil scavenge pump, be connected fuel feed pump between fine filter and the washtub, on inlet line, also be connected to oil filling pipe outside before the oil scavenge pump.

The utility model adopts above-mentioned three-stage filtration, and its operation principle is: elementary and middle rank mainly is that the mechanical admixture in the cleaning solution is reclaimed in filtering, and final stage is to utilize the active carbon material of smart filter core to adsorb organic impurities in the cleaning solution.Further decompose, primary filter filters fine hair, bulky grain earth etc., so primary filter can be by cloth bag or nylon wire or felt or coarse sand or metal fillings realization.The middle rank filter filters the first order and filters omission thing and fine grained earth, and therefore intermediate filter can adopt net formula or edge type or sintered type filtration device structure.

That primary filter can rotate around central shaft by one, constitute at the garden type lattice plate that has one or several hole clippings on the edge and one or several filter bags of being contained on the hole clipping, above primary filter, have the fuel tank loam cake.

When realizing the utility model, can make that intermediate filter cavity is the cylinder that a side surface all seals with the upper end, the lower surface opening communicates with fuel tank that is positioned at one jiao of fuel tank, intermediate filter is located at that this cavity is interior, end interface joins with it under the fuel sucking pipe.Be provided with washtub liquid level control valve, this pipe upper end joins with the washtub sidewall, lower end and oil return pipe join.The final stage fine filter vertically is provided with, and that its underpart is is cone-shaped, cone tip part connects a pipeline to oil return pipe by a blowoff valve.With ball valve on the oil return pipe and connect one and be subjected to the timer-operated electromagnetic valve branch road of wash time.

The utility model advantage is:

Owing to adopted three grades to filter step by step, can guarantee that washing agent is cleaner, can reach better clean result to washing clothes; Can prolong 4～5 times of the smart life-spans that crosses filter core, the complete machine operating cost is reduced; The cleaning of primary filter has been substituted direct cleaning to fuel tank, and the former, easy operating simpler than the latter; Reduce and shut down the frequency of cleaning, thereby increase work efficiency.

Fig. 1 is the utility model embodiment general structure schematic diagram.

Fig. 2 is an Oiltank structure schematic diagram among the utility model embodiment.

Below in conjunction with drawings and Examples the utility model is done further narration:

With reference to accompanying drawing, fuel tank 11 is set, fuel tank 11 lids are contained on the primary filter loam cake 30 below in whole box body 1.Primary filter adopts cloth bag in this example, the cloth bag 13 of cloth envelop collector is contained on the lattice plate 29, the lattice plate can freely rotate around axle 12, mandrel 12 is fixed on and covers on 30, lattice plate 29 is bearing on the garden iron hoop 33, cloth envelop collector loam cake 30 usefulness flanges are connected with fuel tank, can make cloth bag align the 32 convenient taking-up cloth bags cleanings of fuel tank loam cake thereby rotate the lattice plate.Angle of fuel tank is equipped with intermediate filter, adopt network structure in this example, well strainer 14 is contained in the bucket 16 of lower ending opening, bucket 16 is welded on the fuel tank 11, well strainer flowline and bucket 16 loam cakes weldering one, fastening with bolt with bucket 16 flanges, form oil pump oil suction loop by oil pump 20, check valve 17, the oil pump 20 fuel-displaced fine filters 25 that enter, fine filter 25, peep hole 26, washtub are formed oil pump 20 and are gone out oil return line, fine filter 25 is vertically placed, and dirt falls within its bottom cone automatically, enters cloth envelop collector through blowoff valve 22.High liquid level (HLL) in the level control oil pipe 35 control washtubs, washing agent is through oil pipe 35 or electromagnetic valve 8 in the washtub, ball valve 9 is got back in the cloth envelop collector, washtub connects by big or small pulley belt with double speed load motor 6, the drive washtub rotates, washtub, washs outer bucket and is connected with casing 1 by counterweight, spring 2, shock absorber 7 with bearing sealed ring and the outer bucket supporting of washing by axle.Behind circulation cleaning repeatedly, cleaning solution need be replenished, and arm 18 promptly is the outer oil filling pipe that is used for adding cleaning solution.

The utility model washing part operation program and the course of work are as follows:

Opening washtub door knob clothing packs in the washtub 4, selector switch as required shuts up the door carefully, reserve washing, return liquid, the drying time, press start button, promptly enter automatic washing, Oil pump electrical machinery 19 rotates and drives the oil pump oil pumping, and double-speed motor just, anti-low speed rotation, dry cleaning agent is evacuated to fine filter through well strainer, enter bucket in the washing by the road, the interior bucket of washing constantly rotating washs, and the dry cleaning agent liquid level is by pipe 35 controls, and be back to fuel tank top cloth envelop collector through valve 9, cloth bag filters out short flannel earth, and dry cleaning agent is got back to fuel tank and finished circulation, when having washed, electromagnetic valve 8 is opened, binary channel returns liquid fast, returns liquid and finishes, and beginning rotation at a high speed dries, dry and finish the back power failure, having a power failure can open the door in 2～3 minutes gets work.
