A boost control component 7 connected thereto is fixedly installed on the immediate treatment pipe 4. A sewage detector 9 matched thereto is fixedly installed on the sewage input pipe 3. The right end of the immediate treatment pipe 4 is connected to the input end of the pretreatment filter 11, the left end of the storage input pipe 5 is connected to the input end of the liquid storage tank 12, and the output end of the liquid storage tank 12 is connected to the input end of the pretreatment filter 11;

[0031] An intelligent controller 6 is fixedly installed at the rear end of the liquid inlet tee 2, and a pretreatment control system is mounted in the intelligent controller 6. The pretreatment control system includes a control processing unit, and the input end of the control processing unit is connected to a processing program setting unit, a sewage state collection unit and a processing pressure collection unit, and the output end of the control processing unit is connected to a diversion control unit, a pressure floating control unit and a pretreatment data output unit;

[0032] The input end of the processing program setting unit is connected to the PC end signal through a wireless transmitter, the input end of the sewage state acquisition unit is connected to the sewage detector 9 signal, the input end of the processing pressure acquisition unit is connected to the boost control component 7 signal, the output end of the shunt control unit is respectively connected to the liquid inlet tee 2 and the stop valve 8 arranged on the storage input pipe 5, the output end of the pressure floating control unit is respectively connected to the boost control component 7 and the stop valve 8 arranged on the instant processing pipe 4, and the output end of the pre-processing data output unit is connected to the PC end signal through a wireless transmitter. Through the cooperation of the instant processing pipe 4, the storage input pipe 5, the boost control component 7, the stop valve 8, the sewage detector 9 and the pre-processing control system, on the one hand, the laboratory can be The state of sewage is detected, and a suitable pretreatment method is selected according to its pollution properties. While effectively promoting the adaptability of the device body 1 to laboratory sewage, energy saving and environmental protection are achieved. On the other hand, the device body 1 can adjust the applicability of the pretreatment pressure according to the pretreatment methods of laboratory sewage in different states, so that the device body 1 has a dual treatment mode, which increases its functionality. While effectively reducing the damage to the structure of the device body 1 caused by insufficient flow and pressure, and ensuring the structural stability and service life of the device body 1, it can also improve the efficiency and effect of the device body 1 on the pretreatment of laboratory sewage, promote the pretreatment quality of the device body 1 on laboratory sewage, and further promote the environmental protection and economy of the device body 1.

[0033] Figure 3 - Figure 5The boost control assembly 7 is shown to include a control sleeve 71 fixedly sleeved on the instant processing pipe 4, a boost tank 73 connected to the instant processing pipe 4 is fixedly connected to the upper end of the control sleeve 71, sleeve brackets 72 are fixedly connected to the left and right ends of the control sleeve 71, and the boost tank 73 is fixedly arranged between the two sleeve brackets 72, a hydraulic push rod 74 is fixedly installed on the upper end of the sleeve bracket 72, the output end of the pressure floating control unit is connected to the hydraulic push rod 74 signal, a support ear push plate 75 located at the upper end of the boost tank 73 is fixedly connected between the two hydraulic push rods 74, a pressure regulating plug 77 is slidably arranged in the boost tank 73, a connecting rod 76 is fixedly connected to the upper end of the pressure regulating plug 77, and the upper end of the connecting rod 76 extends It is fixedly connected to the outer side of the booster tank 73 and the support ear push plate 75. Through the setting of the booster tank 73, the sewage entering the pretreatment filter 11 can be pressurized, thereby promoting the flow and pressure increase effect of the small amount of sewage to be treated immediately, ensuring its pretreatment effect, and reducing the structural damage to the device body 1. The pressurization space of the booster tank 73 is regulated by the hydraulic push rod 74 in cooperation with the pressure regulating plug 77 and the support ear push plate 75, thereby achieving the adjustability and applicability of the pressurization effect of the booster tank 73, promoting the pressure regulation range of the booster tank 73, and then achieving the function of pressure regulation of laboratory sewage in different states, so that the device body 1 can effectively cope with the randomness of laboratory sewage.

[0034] Figure 2 - Figure 5 It is shown that a pressure detection probe is fixedly installed at the lower end of the pressure regulating plug 77, and the input end of the processing pressure acquisition unit is connected to the signal of the pressure detection probe. The setting of the pressure detection probe can assist the control processing unit in data detection and feedback of the pressure regulation of laboratory sewage through the pressure floating control unit, and can effectively realize the pressure control self-inspection effect of the pretreatment control system and promote its accuracy of pressure regulation.

[0035] Figure 2 It is shown that the output end of the control and treatment unit is also connected to a pressurization and emptying unit, and the output end of the pressurization and emptying unit is connected to the signal of the hydraulic push rod 74. The setting of the pressurization and emptying unit can, after the pressurization and regulation of the laboratory sewage to be immediately treated, perform pressurization and emptying of the retained sewage in the boosting tank 73, effectively ensuring the unified treatment effect of all laboratory sewage, and avoiding the laboratory sewage from being retained in the boosting tank 73, causing durability damage to the boosting tank 73.

[0036] Figure 1 - Figure 5It is shown that when the device body 1 is set for laboratory application, the relevant technicians first set the parameters and programs for laboratory sewage pretreatment to the processing program setting unit through the PC, including but not limited to the dual-mode program for laboratory sewage treatment - immediate treatment mode and centralized treatment mode, the benchmark data for the degree of pollution of laboratory sewage detection, the rated pressure data of the device body 1 for sewage pretreatment and other related parameter data and control programs, and then the processing program setting unit transmits the received pretreatment parameter program to the control processing unit, and the control processing unit processes and applies these data.

[0037] Then, when sewage is discharged from the laboratory, the sewage will first enter the sewage input pipe 3 through the laboratory's discharge pipe. The non-pass valve 8 on the sewage input pipe 3 is kept in a constantly open state, so the sewage will gradually flow through the sewage detector 9. The sewage detector 9 collects pollutant content data, flow data and pressure data of the sewage, and then transmits the collected data to the sewage state collection unit. The sewage state collection unit transmits the sewage state data at this time to the control processing unit, and the control processing unit judges the received sewage data;

[0038] When it is determined that the pollution degree of the sewage is not high, it is determined that the sewage at this time is in a state that can be centrally treated, and then the control instruction is transmitted to the diversion control unit, so that the diversion control unit first controls the liquid inlet tee 2 to open the channel connecting the sewage input pipe 3 to the storage input pipe 5, so that the sewage in the sewage input pipe 3 can flow into the storage input pipe 5, and then opens the stop valve 8 located on the storage input pipe 5, so that the sewage can flow through the storage input pipe 5 to the input end of the liquid storage tank 12, and then enter the liquid storage tank 12 for storage, waiting for subsequent centralized treatment. After all the sewage is stored, the diversion control unit re-closes the liquid inlet tee 2 and the stop valve 8 located on the storage input pipe 5;

[0039] When it is determined that the pollution degree of the sewage is high, it is determined that the sewage at this time is in a state of needing immediate treatment, and then the control instruction is transmitted to the diversion control unit and the pressure floating control unit. The diversion control unit controls the liquid inlet tee 2 to open the channel connecting the sewage input pipe 3 to the immediate treatment pipe 4, so that the sewage in the sewage input pipe 3 can flow into the immediate treatment pipe 4. The pressure floating control unit controls the hydraulic push rod 74 to extend according to the sewage flow and pressure data at this time, so that the support ear push plate 75 drives the connecting rod 76 and the pressure regulating plug 77 to move upward through the support ear push plate 75, so that the pressure regulating plug 77 releases the liquid storage amount in the boosting tank 73, and controls the pressure regulating plug 77 according to the pressure data regulated by the need. The upward movement height, then the sewage entering the immediate treatment pipe 4 will flow into the space of the boosting tank 73, filling the boosting tank 73, and the pressure detection head located at the lower end of the pressure regulating plug 77 will detect the pressure data in the boosting tank 73 at this time, and then transmit the data to the processing pressure acquisition unit, and the processing pressure acquisition unit will transmit the pressure data to the control processing unit. After judging that the pressure data in the boosting tank 73 at this time reaches the set data value, the control instruction will be transmitted to the pressure floating control unit. The pressure floating control unit controls the stop valve 8 on the immediate treatment pipe 4 to open, so that the sewage after the pressurization is completed passes through the immediate treatment pipe 4 into the pretreatment filter 11 for immediate pretreatment;

[0040] When the pretreatment filter 11 continues to perform immediate pretreatment on the sewage, the sewage detector 9 will transmit the sewage data it continuously senses to the sewage status collection unit, and the sewage status collection unit will continuously transmit the sewage status data to the control and processing unit. After the control and processing unit determines that the laboratory has finished discharging this type of sewage, it will transmit the emptying instruction to the boosting emptying unit and the diversion control unit. First, the diversion control unit controls the closure of the liquid inlet tee 2 to cut off the connection between the sewage input pipe 3 and the immediate treatment pipe 4, and then the boosting emptying unit controls the hydraulic push rod 74 to produce a rapid contraction effect. The rapid contraction of the hydraulic push rod 74 drives the ear push plate 75 and the connecting rod 76 to prompt the pressure regulating plug 77 to move down rapidly in the boosting tank 73, thereby allowing the sewage in the boosting tank 73 to be quickly emptied. In this way, the pressure of the sewage flowing out of the boosting tank 73 is promoted, and the pressure effect of the subsequent part of the sewage entering the pretreatment filter 11 is guaranteed, thereby promoting the treatment effect of the device body 1 on all sewage and reducing the structural damage of the device body 1 caused by pressure fluctuations.

[0041] During the process of centralized or immediate pretreatment of sewage by the device body 1, the control and processing unit will transmit the sewage pretreatment data to the pretreatment data output unit, and the pretreatment data output unit will transmit the data to the PC, so as to facilitate laboratory technicians to view the application process of the device body 1 and to manage and control the device body 1.

[0042] Second implementation method:

[0043] Figure 1 and Figure 3 - Figure 7 A laboratory sewage pretreatment device is shown. On the basis of the first embodiment, the following functions are added: the input end of the control processing unit is also connected to a storage liquid level acquisition unit, and the input end of the storage liquid level acquisition unit is connected to the liquid level sensor signal arranged in the liquid storage tank 12. The setting of the storage liquid level acquisition unit can effectively collect data on the storage volume of laboratory sewage that needs to be centrally treated in the liquid storage tank 12, and send data reminders to relevant laboratory personnel after the storage volume reaches the upper limit, reminding them to treat the centrally treated laboratory sewage, so as to ensure the timeliness and effectiveness of laboratory sewage treatment, and also ensure the service life of the liquid storage tank 12 to avoid damage and loss caused by excessive storage.

[0044] Figure 6 and Figure 7 It is shown that the output end of the control processing unit is also connected to a sewage pretreatment control unit, which includes a pretreatment data receiving module whose input end is connected to the control processing unit signal, the output end of the pretreatment data receiving module is connected to the sewage control instruction processing module, the output end of the sewage control instruction processing module is connected to the centralized processing module and the priority guarantee module, the output end of the centralized processing module is connected to the pump signal arranged on the liquid storage tank 12, and the output end of the priority guarantee module is connected to the centralized processing module signal. The setting of the sewage pretreatment control unit can, on the one hand, promote the automation and intelligence of the device body 1, and can automatically execute and control the laboratory sewage that needs centralized treatment stored in the liquid storage tank 12, and can also generate the control auxiliary effect of the priority instruction when facing the laboratory sewage that needs immediate treatment, thereby ensuring that the device body 1 is highly applicable to laboratory sewage, and at the same time, it can effectively avoid the treatment conflict of laboratory sewage in different states, realize the coordination effect of the dual treatment mode of the device body 1, and ensure the timeliness and effectiveness of laboratory sewage treatment.

[0045] Figure 6 and Figure 7It is shown that the input end of the liquid storage tank 12 is connected to the output end of the water pump through an overflow pipe, and an overflow valve is arranged on the overflow pipe. The output end of the sewage control instruction processing module is also connected to an anti-overflow module, and the output end of the anti-overflow module is connected to the overflow valve signal. The setting of the anti-overflow module can enable the intercepted laboratory sewage to flow back to the liquid storage tank 12 when the device body 1 intercepts the centralized laboratory sewage for treatment, so as to wait for subsequent pretreatment, thereby avoiding the laboratory sewage from being retained in the pipeline or overflowing due to excessive pressure, and effectively ensuring the effectiveness and safety of the dual-treatment mode application of the device body 1.

[0046] Figure 1 and Figure 3 - Figure 7 It is shown that the sewage determined to be capable of centralized treatment enters the liquid storage tank 12 for storage, the liquid level sensor of the liquid storage tank 12 detects the amount of sewage stored therein, and then transmits the data to the storage liquid level acquisition unit, the storage liquid level acquisition unit transmits the liquid level data to the control processing unit, the control processing unit determines the action node for sewage treatment in the liquid storage tank 12 according to the liquid level data of the liquid storage tank 12, when the sewage liquid level in the liquid storage tank 12 reaches the node that needs to be treated, the control processing unit transmits the centralized treatment control instruction to the pretreatment data receiving module in the sewage pretreatment control unit, the pretreatment data receiving module transmits the data to the sewage control instruction processing module, the sewage control instruction processing module transmits the centralized pretreatment instruction to the centralized processing module according to the received control instruction, the centralized processing module starts the pumping pump, so that the pumping pump pumps out the sewage in the liquid storage tank 12, and passes it into the pretreatment filter 11 for pretreatment;

[0047] In the process of the centralized processing module working through the pump, if the laboratory discharges sewage that needs immediate treatment into the sewage input pipe 3, the control processing unit transmits the control instruction to the pretreatment data receiving module in the sewage pretreatment control unit after receiving the data transmitted by the sewage status acquisition unit at this time. The pretreatment data receiving module transmits the control data to the sewage control instruction processing module, and the sewage control instruction processing module transmits the immediate pretreatment instruction to the priority guarantee module and the anti-overflow module respectively, so that the priority guarantee module turns off the function of the centralized processing module, and the anti-overflow module opens the overflow pipe channel connected to the pump, so that the sewage that is often present in the liquid storage tank 12 and input into the pretreatment filter 11 pipeline flows back to the liquid storage tank 12 through the overflow pipe;

[0048] At the same time, the treatment unit is regulated to the diversion regulation unit and the pressure floating regulation unit. The diversion regulation unit controls the liquid inlet tee 2 to open the channel connecting the sewage input pipe 3 to the side of the immediate treatment pipe 4, so that the sewage in the sewage input pipe 3 can flow into the immediate treatment pipe 4. The pressure floating regulation unit controls the hydraulic push rod 74 to extend according to the sewage flow and pressure data at this time, releases the liquid storage volume in the boosting tank 73, so that the sewage entering the immediate treatment pipe 4 will flow into the space of the boosting tank 73. The pressure detection head will detect the pressure data in the boosting tank 73 at this time, and then transmit the data to the treatment pressure acquisition unit. The treatment pressure acquisition unit transmits the pressure data to the treatment pressure acquisition unit. The regulating and controlling unit, after judging that the pressure data in the boosting tank 73 has reached the set data value, transmits the regulating instruction to the pressure floating regulating and controlling unit. The pressure floating regulating and controlling unit controls the stop valve 8 on the immediate treatment pipe 4 to open, so that the sewage after the pressurization is completed enters the pretreatment filter 11 through the immediate treatment pipe 4 for immediate pretreatment, thereby effectively ensuring the effectiveness and safety of the dual-mode application of the device body 1 for laboratory sewage pretreatment, ensuring the effect of the device body 1 on laboratory sewage pretreatment, while improving the environmental protection of the device body 1, promoting the energy-saving effect of the device body 1, and improving the economic benefits of the laboratory application device body 1.

[0049] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
