[0002] Chemical nickel plating wastewater contains a large amount of hypophosphite, phosphite and other reducing substances. There are also nickel complexes in the wastewater, and most of these complexes have strong complexing properties for nickel, such as nickel citrate. Due to the complex composition of chemical nickel plating wastewater, including inorganic salts, complexes, organic matter, etc., the treatment of chemical nickel plating wastewater is relatively difficult, and any single method cannot achieve a good treatment effect. At present, the treatment of waste liquid and wastewater mainly adopts chemical precipitation, electrolysis, ion exchange, catalytic reduction, electrodialysis, membrane osmosis, biological method, etc., and some are combined with two or more methods. Although some treatment methods have better effects, the process of treating waste liquid is complicated, the stability is poor, and the cost is high.

[0003] The existing equipment is a combination of multiple devices, a non-integrated structure, and has shortcomings when used. Summary of the invention

Summary of the invention

[0008] After starting the equipment, the control system starts the centrifugal pump, and uses the principle of the Venturi ejector to evacuate the pressure in the evaporation system container to a vacuum, with a vacuum degree of >92KPa. After the raw liquid is introduced into the separator with the help of negative pressure, the self-priming pump starts the raw liquid circulation mode;

[0009] After the compressor is started, the refrigerant absorbs the low-level heat source in the air and converts it into a high-temperature clean heat source after compression. The refrigerant indirectly heats the waste liquid in the heat exchanger.

[0010] The waste liquid solvent water and the solute are physically separated in the separator by using the different boiling points. The solvent should be heated to become water vapor. The water vapor enters the condenser body and exchanges heat indirectly with the coolant, and then condenses into water droplets. The water droplets are collected in the water storage tank and then quantitatively discharged through the drainage centrifugal pump.

[0011] The solute in the waste liquid is retained in the separator, and when the solute reaches the set concentration, it is discharged through the diaphragm pump.

When the foam grows to the set position, the single-chip microcomputer processes the information and transmits it to the water pump. The water pump starts, and the defoaming agent is added to the separator through the liquid inlet pipe.

The reinforcement plate can improve the anti-deformation performance of the first shell, the second shell and the third shell. Start the drive motor, and the shaft drives the scraper to rotate. During the rotation of the scraper, the bottom end of the separator can be cleaned.

[0013] Preferably, the foam sensors are symmetrically arranged, and the foam sensors are vertically and centrally symmetrically distributed through the separator. Symmetrically arranged foam sensors can improve detection effect.

[0015] Preferably, the cleaning mechanism comprises a driving motor, a scraper and a rotating shaft, wherein the driving motor is installed at the bottom end of the separator, the top end of the driving motor is installed with a rotating shaft, and the outer side of the rotating shaft is installed with a scraper. The cleaning mechanism is convenient for cleaning the bottom end of the separator.

[0016] Preferably, the bottom end of the scraper is close to the bottom end of the separator, and the width of the scraper is smaller than the width of the separator. The scraper can play a certain cleaning role.

[0017] Preferably, the condenser body is an air-cooled condenser. The air-cooled condenser can improve the condensation effect of steam.

[0018] Preferably, the protective structure includes a reinforcing plate, a soundproofing plate and an anti-corrosion plate, the reinforcing plates are all installed on the inner side of the third outer shell, the second outer shell and the first outer shell, the inner side of the reinforcing plates are all installed with soundproofing plates, and the inner side of the soundproofing plates are all installed with anti-corrosion plates. The protective structure can play a certain protective role on the third outer shell, the second outer shell and the first outer shell, and improve their use effect. Beneficial Effects

[0019] The low-temperature heat pump concentrator and reducer provided by the present invention has the following advantages:

[0020] The present invention provides a low-temperature heat pump concentration and reduction integrated machine, which integrates multiple devices, has a simple structure and high working efficiency;

[0021] Through the foam sensor symmetrically arranged on the inner wall of the separator, one end of the liquid inlet pipe is connected to the defoaming agent storage box. The foam sensor can detect the foam position in the separator and transmit the information to the single-chip microcomputer. When the foam grows to the set position, the single-chip microcomputer processes the information and transmits it to the water pump. The water pump starts and the defoaming agent is added into the separator through the liquid inlet pipe, thereby achieving the purpose of automatically adding the defoaming agent.

[0022] By arranging the anti-corrosion plates on the inner sides of the first shell, the second shell and the third shell, the anti-corrosion performance and noise reduction performance of the first shell, the second shell and the third shell can be enhanced under the protection of the anti-corrosion plates and the sound insulation plates, and the reinforcement plates can improve the anti-deformation performance of the first shell, the second shell and the third shell;

[0023] By starting the driving motor arranged at the bottom of the separator, the rotating shaft drives the scraper to rotate. During the rotation of the scraper, the bottom of the separator can be cleaned to avoid the problem of material waste caused by material residue on the separator. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0033] See also Figure 1-5The low-temperature heat pump concentration and reduction integrated machine provided by the present invention includes a first shell 3, a second shell 5 and a third shell 6. A display screen 10 is installed at one end of the first shell 3, and a separator 11 is installed inside the first shell 3. The separator 11 is provided with components such as a diaphragm pump, a compressor, a heat exchanger and a self-priming pump. An inlet 2 is installed on one side of the separator 11. A detection structure 1 is provided on the inner wall of the separator 11. The detection structure 1 includes a water pump 101, a liquid inlet pipe 102, a single-chip computer 103 and a foam sensor 104. The foam sensors 104 are symmetrically installed on the inner wall of the separator 11. The single-chip computer 103 is installed on one side of the first shell 3, the water pump 101 is installed on one side of the first shell 3, and the liquid inlet pipes 102 are installed at both ends of the water pump 101. The foam sensors 104 are symmetrically arranged, and the foam sensors 104 are vertically symmetrically distributed through the separator 11.

[0034] The input end of the foam sensor 104 is electrically connected to the output end of the single chip microcomputer 103 , and the output end of the single chip microcomputer 103 is electrically connected to the input end of the water pump 101 .

[0035] A second shell 5 is installed on one side of the first shell 3, and a condenser body 8 is arranged inside the second shell 5. The condenser body 8 is an air-cooled condenser. A third shell 6 is installed on one side of the second shell 5, and a water tank 7, an ejector, a centrifugal pump and other components are arranged inside the third shell 6.

[0036] In this embodiment, after starting the equipment, the control system starts the centrifugal pump, and uses the Venturi ejector principle to evacuate the pressure in the evaporation system container to a vacuum, with a vacuum degree of >92KPa. After the raw liquid is introduced into the separator 11 with the help of negative pressure, the self-priming pump starts the raw liquid circulation mode.

[0037] After the compressor is started, the refrigerant absorbs the low-level heat source in the air and converts it into a higher temperature clean heat source after compression. The refrigerant indirectly heats the waste liquid in the heat exchanger.

[0038] The waste liquid solvent water and the solute are physically separated by utilizing the different boiling points in the separator 11, wherein the solvent is heated to become water vapor, and the water vapor enters the condenser body 8 and the coolant for indirect heat exchange and then condenses into water droplets, which are collected in the water storage tank 7 and quantitatively discharged through the drainage centrifugal pump.

[0039] The solute in the waste liquid is retained in the separator 11, and when the solute reaches a set concentration, it is discharged through a diaphragm pump.

[0040] The threshold value of harmful exhaust gas emitted during the evaporation process is far lower than the national standard, and there is no need to connect to the exhaust system.

[0041] One end of the liquid inlet pipe 102 is connected to the defoaming agent storage box. The foam position in the separator 11 can be detected by the foam sensor 104, and the information is transmitted to the single-chip computer 103. When the foam grows to the set position, the single-chip computer 103 processes the information and transmits it to the water pump 101. The water pump 101 starts and adds defoaming agent into the separator 11 through the liquid inlet pipe 102. The defoaming agent inhibits the continued increase of foam, thereby effectively controlling the poor water production caused by the equipment turning over. Example

The driving motor 401 is installed at the bottom end of the separator 11, and the rotating shaft 403 is installed at the top of the driving motor 401. The scraper 402 is installed on the outer side of the rotating shaft 403. The bottom end of the scraper 402 is close to the bottom end of the separator 11, and the width of the scraper 402 is smaller than the width of the separator 11.

[0044] In this embodiment, the anti-corrosion performance and noise reduction performance of the first shell 3, the second shell 5 and the third shell 6 can be enhanced to a certain extent through the protective effect of the anti-corrosion plate 903 and the sound insulation plate 902. The reinforcing plate 901 can improve the anti-deformation performance of the first shell 3, the second shell 5 and the third shell 6 to a certain extent. The drive motor 401 is started, and the rotating shaft 403 drives the scraper 402 to rotate. During the rotation of the scraper 402, the bottom end of the separator 11 can be cleaned to prevent material from remaining on the separator 11.
