(54) INSTALLATION FOR CLEANING LIQUIDS

}. The invention relates to a device for the purification and separation of various suspensions and can be used in the MH o fields of industry, in particular, in mechanical engineering for the cleaning of coolants used in grinding. An erection unit for cleaning coolant in grinding machines, including a pump, hydrocyclone (hydrocycle battery), main coolant tank, sludge piping 6aKj .; Contaminated coolant from the machine is fed into the main tank, the pump feeds it to the hydrocyclone where cleaning takes place. Coolant flow to the machine .1 / |. Installations have a low degree of purification, are inconvenient in operation. Closest to the proposed technical dryness and the achieved result is the installation containing the main tank for coolant fluids, HacoCj separator, hydrocyclone Purified with inlet, drain and Sand pipe, sludge tanks, connecting pipes and valves, In a known installation Contaminated coolant flows from the machine to the separator where the coolant is first cleaned and then to the main tank. The pump sucks coolant from the main tank and supplies it for final cleaning to the hydro-slope, from which the purified liquid can be fed directly into the grinding zone or through the cutting valve of the main tank. The contaminated liquid from the sludge nozzle of the hydrocyclone flows into the sludge tank, where sludge occurs, after which the liquid lag with the liquid flows into the main tank 21. The main tank has a rectangular forivQT and a large volume due to the need to cool the coolant after participating in the grinding process. The deposition of particles is due to the fact that it is not possible to clean the coolant by 100% in the separator to completely stand in the sludge bed. The remaining particles in the coolant contaminant fall to the bottom. the tank with a long -j nominee soybean in it due to the lack of sufficient circulation throughout the tank. Gradually, particles of schlama grow together to form a silt. The usable tank volume is reduced. When the level of sludge settled on the bottom reaches the pump suction patr. The unit may stop working altogether. It is necessary to turn off the unit, drain the SOC and clean the tank. This is a time consuming operation that is usually performed by | Manually. ::,. :: Thus, osjjenivlyimy at the bottom of the main tank leads to a reduction in the useful tank, the need for frequent cleaning - time-consuming operation using the JK loss of working time at the installation, i.e., to reduce the period of continuous operation installation without cleaning the main tank. . The purpose of the invention is to reduce the cost of manual labor for its maintenance and increase the effectiveness of the use of equipment ...- ... .-. . This is achieved by installing a system that contains a main tank for cutting fluids, a pump, a separator, a hydrocyclone with inlet, SLN and Sand pipes, sludge tanks, connecting pipes and a shut-off device. It is equipped with a circulation device, one of which is implemented in the form of a perforated pipeline installed at the bottom of the main tank. along its walls and connected to the pressure line of the pump, and the other is made in the form of a tee, placed on the core of the pipeline through which the drain pipe of the hydrocyclone is connected to the main tank. Introduce circulating devices into the backfilled zone of the main tank. It uses the kinetic energy of the stream entering the coolant tank to lift the settled sludge particles from the bottom of the tank. The device circulates coolant through the KOHTypjy tank, in which the sludge particles are suspended and removed from the tank with the coolant flow. Through the pump and hydrocyclone, where they are separated from the coolant flow. 9 . 3.4 In this way, the use of circulation devices eliminates the deposition of sludge in the main tank, reduces the cost of manual labor for processing, increases the efficiency of equipment use. FIG. 1 shows the installation diagram; in fig. 2 — a fork A in FIG. 1 (tank clears); in fig. 3 — nozzle unit for cyclion; in fig. 4 is a section of MBG; FIG. 3. Equipment for cleaning. SOZH srderisite pp. 1m of the main coolant tank 1, centrifugal pump 2, separator 3, hydro-slope 4, sludge tank 5 for sludge slurry coming out of the cyclone sludge pipe, sludge tank for sludge, mounted on the depressor 3, the circulation device 7, is located in the stagnant space of the main tank, the nozzle 8, the valve, valve 9, served to regulate the pressure before the crank valve 10, listened to the regulation of the pressure supplied by to the machine, pipeline 11, coeJaan tion pipe ROJixx. with the input itaTj KOM of the hydro-cyclone 4.

Hose circulation device 7 / is a pipeline 23 with openings 24 along its entire length. Hose circular device tion is located at the bottom of the main tank and the Scholl of its walls is placed. A new circulation device 8 is attached at the end T1 of the bushing 14c (a wide thread. It is a tee 25, the two ends of which are plugged with plugs 26. Each plug 26 has an opening 27 in the side wall. Assembling the hole 27 of plugs 26 The installation works as follows .. Before starting the installation, the valve QV nepeKffciBaq enters the access of the liquid into the hydro cyclone, and then turns on the pump 2 The pump 2 sucks the liquid from the main tank 1 and supplies it with pressure to the pipeline 11 when reaching in 1ru power supply 11 pressure pressure; Higher than the set pressure of the spring of the safety valve 18, the relief valve 1% passes and passes the liquid through the pipe 23 of the circulation device 7 to the main tank .. ..,. ,: ,,,., The fluid, which is under pressure in pipe 423, flows into the main tank 1, is throttled through the holes 24. In this case, the liquid has a large kinetic energy, which is used to bring the sludge particles suspended to the bottom of the main tank 1.. After a certain amount of time has passed, during which time (Slug ticks, lying on the bottom of the base tank) will go into suspension, turn on the machine and start the process with parts 1 E. Filling i1 i. The grinding process with sludge particles and the abrasive coolant enters the separator 3 where it is pre-cleaned. The pre-cleaned SCREW is drained through the hole 2O into the main tank 1, and the lost sludge enters the slag tank 6. Open the taps 9 and 10, the liquid with suspended weights is dispensed with nasby 2 and From the main tank through the TRT pipeline 11 to the hydrocyclone 4. The pressure in the pipe 15 decreases below the opening pressure of the valve 18. At the same time, the valve 18 is closed, blocking the access of the liquid to the circulating hose device 7. In 1x1X cyclone 4, the final cleaning of the coolant occurs. Pure coolant on the output of the 1-line hydrocyclone .4 goes to the machine. Slurry slurry from the sand pipe of the hydrocyclone 4 enters the slurry tank 5. When the slurry slurry is reached in the slurry tank, the hose goes into the main tank 1. The grinding process (installation, removal of the part) requires periodically closing the crankshaft & 10. The coolant in line 12 increases. When it reaches the pressure of the valve 17, the valve opens the DS / s blunt coolant to the main tank. Under pressure, the coolant enters the co-circulation device 8, where it is throttled with holes 2.7. ; (The light energy of the jets, the output of the MIC from the openings 27 11 of the opposite direction, is sufficient for the sludge particles to go down from the bottom in the aanthra of the main tank: 1 and prevents the sludge particles from settling down and the bottom of the tank. Slag device 7 15 m in front of the billing operation on the flock.The coping device 8 does not require additional costs: power costs and pa6tnaev for a short period of time during the first time during the entire operation of the main tank. it's smart sew the sludge sedimentation on the main tank to reduce the cost of manual labor during maintenance of the installation, improve the efficiency of equipment use.It is trying to use qiqi qiqi devices to show that the use of kakhshogr from devices n "" means to increase the output by 30% The same economic efficiency, the effect is not less than Vr.
