Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a water quality testing device for hydrochloric acid desorption wastewater treatment. Background Technology

[0002] Hydrochloric acid desorption wastewater refers to acidic wastewater containing hydrochloric acid generated during industrial production processes due to the use of hydrochloric acid for chemical treatment. Currently, the treatment process for hydrochloric acid desorption wastewater typically involves filtration and precipitation pretreatment, neutralization treatment, membrane concentration treatment, deep desalination treatment, water quality testing, and recycling treatment.

[0003] Currently, a Chinese patent (authorization announcement number CN219751934U) discloses a hydrochloric acid wastewater treatment tank with real-time detection function. The tank has inlets installed at the front and rear, and chutes on both sides. A crossbar is installed within the chutes, and a support base is installed in the middle of the crossbar. The support base is located at the front end of the inlet, and a support rod is welded to its upper surface. A water quality detection device is fixed to the top surface of the support base. Two batteries are fixed to the right side of the water quality detection device, located on the support base. A detection probe is located below the support base and connected to the water quality detection device via wiring. The chutes and crossbar structure on both sides of the tank, along with the water quality detection device fixed above the crossbar, enable the device to move, facilitating sampling at different locations within the tank. The water quality detection devices on both sides of the inlet simultaneously sample and detect the inlet and outlet, achieving real-time monitoring of the wastewater tank.

[0004] As can be seen from the above reference case, the above device sets up a sliding water quality detection device above the wastewater treatment tank. Although this can facilitate the detection of water quality at different locations, since the above device only uses a line to connect the detection probe to the water quality detection device, when the water quality detection device moves the detection probe through the line, this will pull on the connection between the water quality detection device and the detection probe and the line. This will not only reduce the stability of the connection between the water quality monitoring device and the detection probe and the line, but also make it difficult to ensure the stable operation of the detection probe in the wastewater treatment tank.

[0005] Based on this, this utility model designs a water quality testing device for hydrochloric acid desorption wastewater treatment to solve the above problems. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, this invention provides a water quality testing device for hydrochloric acid desorption wastewater treatment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A water quality testing device for hydrochloric acid desorption wastewater treatment includes a testing tank, a displacement mechanism slidably connected to the top of the testing tank, a water quality analyzer fixedly connected to the surface of the displacement mechanism, a detection probe electrically connected to the surface of the water quality analyzer, and a directional guiding mechanism sleeved on the surface of the detection probe fixedly connected to one end of the displacement mechanism.

[0009] Furthermore, the directional guiding mechanism includes a U-shaped seat fixedly connected to one end of the displacement mechanism. Both ends of the U-shaped seat are rotatably connected to a rotating shaft. A positioning sleeve fitted onto the surface of the detection probe is fixedly connected between the two rotating shafts. A positioning hole is opened at one end of the U-shaped seat, and an insertion hole communicating with the positioning hole is opened at one end of one of the rotating shafts. A pin that is inserted into the positioning hole is inserted into the insertion hole.

[0010] Furthermore, the directional guidance mechanism also includes a locking assembly, which includes a piston cylinder fixedly connected to the outside of the positioning sleeve. A piston is slidably connected inside the piston cylinder. A threaded rod that is threadedly connected to the piston cylinder is rotatably connected to the top of the piston. A liquid guide tube is fixedly connected to and communicates with the bottom of the piston cylinder. One end of the liquid guide tube extends through to the inside of the positioning sleeve. An elastic liquid bladder fitted on the surface of the detection probe is fixedly connected to and communicates with the other end of the liquid guide tube. The piston cylinder, the liquid guide tube, and the elastic liquid bladder are all filled with water.

[0011] Furthermore, the positioning sleeve has an annular cavity on its inner side, and the elastic fluid bladder is fixedly connected to the inside of the annular cavity.

[0012] Furthermore, a throttle is fixedly connected to the top of the threaded rod, and the corners of the throttle are rounded.

[0013] Furthermore, a guide rod is fixedly connected to the top of the piston, the top of the guide rod extends through the piston cylinder, and the guide rod is parallel to the axis of the threaded rod.

[0014] Furthermore, there are two guide rods, which are symmetrically distributed on both sides of the threaded rod axis.

[0015] Furthermore, there are two positioning holes, and the center points of the two positioning holes and the center point of the rotatable connection between the piston cylinder and the positioning sleeve can jointly form an isosceles right triangle, and the pin is inserted into the positioning hole below.

[0016] Furthermore, a pull ring is fixedly connected to the other end of the pin, and the diameter of the pull ring is larger than the inner diameter of the insertion hole.

[0017] Beneficial effects

[0018] First paragraph: The beneficial effects brought about by the first independent claim of this utility model;

[0019] 1. When the displacement mechanism simultaneously moves the water quality analyzer and the detection probe, the U-shaped seat drives the positioning sleeve to move vertically through the pin and the rotating shaft. The positioning sleeve drives the detection probe to move vertically. At this time, the detection probe and the water quality analyzer are relatively stationary. This can reduce the connection burden between the detection probe and the water quality analyzer. At the same time, the positioning sleeve can also stably lock the detection probe at the corresponding depth of the detection pool, so that the detection probe can more stably perform detection operations on the water passing through.

[0020] 2. After the detection probe is connected to the water quality analyzer through the positioning sleeve, the operator only needs to rotate the threaded rod accordingly. The threaded rod drives the piston closer to the detection probe. At the same time, the piston squeezes the water in the piston cylinder into the liquid guide tube. The liquid guide tube guides the water into the elastic liquid bladder. The elastic liquid bladder fills with water and expands, and firmly wraps around and locks the detection probe along the annular cavity. This not only firmly locks the detection probe inside the positioning sleeve, but also seals the gap between the detection probe and the positioning sleeve, preventing water from entering the interior of the positioning sleeve.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-5 A water quality testing device for hydrochloric acid desorption wastewater treatment includes a quartz sand filter and a testing tank 100. A displacement mechanism 200 is slidably connected to the top of the testing tank 100. A water quality analyzer 300 is fixedly connected to the surface of the displacement mechanism 200, and a detection probe 400 is electrically connected to the surface of the water quality analyzer 300. A directional guiding mechanism 500, sleeved on the surface of the detection probe 400, is fixedly connected to one end of the displacement mechanism 200. The inlet end of the quartz sand filter is connected to a first infusion pump via a flange, and the outlet end of the quartz sand filter is connected to a second infusion pump via a flange. The outlet end of the second infusion pump is connected to a neutralization tank via a flange, and the inlet end of the neutralization tank is connected to a third infusion pump via a flange. An alkaline storage tank is connected via a flange. The outlet of the neutralization tank is connected via a flange to a fourth infusion pump. The outlet of the fourth infusion pump is connected via a flange to an acid-resistant nanofiltration membrane concentration device. The freshwater outlet of the acid-resistant nanofiltration membrane concentration device is connected via a flange to a fifth infusion pump. The outlet of the fifth infusion pump is connected via a flange to a detection tank 100. The outlet of the detection tank 100 is connected via a flange to a circulation pump. The concentrated liquid outlet of the acid-resistant sodium filtration membrane concentration device is connected via a flange to a sixth infusion pump. The outlet of the sixth infusion pump is connected via a flange to a vapor recompression evaporator. The outlet of the vapor recompression evaporator is connected via a flange to a seventh infusion pump. The outlet of the seventh infusion pump is connected via a flange to the detection tank 100.

[0032] After the first infusion pump delivers the hydrochloric acid desorption wastewater to the quartz sand filter, the filter removes solid impurities. The filtered wastewater is then pumped by the second infusion pump to the neutralization tank. Simultaneously, the third infusion pump delivers a measured amount of alkali solution from the alkali storage tank to the neutralization tank, neutralizing the wastewater with the alkali solution. Finally, the fourth infusion pump introduces the treated solution into an acid-resistant nanofiltration membrane concentration unit, which separates the wastewater into fresh water and high-concentration hydrochloric acid / salt solution. The concentrate and fresh water are pumped into the testing tank 100 by the fifth pump. The water quality analyzer 300 monitors the quality of the fresh water in real time through the detection probe 400. If the water quality meets the standards, the circulation pump will pump the fresh water into the factory's circulating water system to achieve zero discharge of acidic wastewater. At the same time, the sixth pump will pump the high-concentration hydrochloric acid / salt concentrate into the vapor recompression evaporator to crystallize and produce industrial salts such as NaCl and CaCl2. Meanwhile, the evaporation condensate is pumped into the testing tank 100 by the seventh pump for recycling.

[0033] The displacement mechanism 200 includes a trolley that is slidably connected to the top of the detection pool 100. An electric trolley is slidably connected to the surface of the trolley. The water quality analyzer 300 and the U-shaped seat 510 are both fixedly connected to the surface of the electric trolley by bolts.

[0034] The directional guidance mechanism 500 includes a U-shaped seat 510 fixedly connected to one end of the displacement mechanism 200. Both ends of the U-shaped seat 510 are rotatably connected to a rotating shaft 520. A positioning sleeve 530 fitted onto the surface of the detection probe 400 is fixedly connected between the two rotating shafts 520. A positioning hole 511 is opened at one end of the U-shaped seat 510. One end of one of the rotating shafts 520 is opened with an insertion hole 521 communicating with the positioning hole 511. A pin 540 is inserted into the positioning hole 511 and is inserted into the insertion hole 521.

[0035] There are two positioning holes 511. The center point of the two positioning holes 511 and the center point of the piston cylinder 551 and the positioning sleeve 530 can form an isosceles right triangle. The pin 540 is inserted into the lower positioning hole 511. This can not only fix the positioning sleeve 530 vertically, but also fix the positioning sleeve 530 horizontally, so that the staff can maintain the detection probe 400.

[0036] The other end of the pin 540 is fixedly connected to a pull ring 560. The diameter of the pull ring 560 is larger than the inner diameter of the socket 521, which reduces the difficulty for the user to insert or remove the pin 540.

[0037] In this embodiment of the utility model, when the displacement mechanism 200 simultaneously drives the water quality analyzer 300 and the detection probe 400 to move, the U-shaped seat 510 drives the positioning sleeve 530 to move vertically through the pin 540 and the rotating shaft 520. The positioning sleeve 530 drives the detection probe 400 to move vertically. At this time, the detection probe 400 and the water quality analyzer 300 are relatively stationary. This can reduce the connection burden between the detection probe 400 and the water quality analyzer 300. At the same time, the positioning sleeve 530 can also stably lock the detection probe 400 at the corresponding depth of the detection pool 100, so that the detection probe 400 can more stably perform detection operations on the passing water.

[0038] It should be noted that the quartz sand filter, neutralization tank, alkali storage tank, acid-resistant sodium filtration membrane concentration equipment, vapor recompression evaporator, first infusion pump, second infusion pump, third infusion pump, fourth infusion pump, fifth infusion pump, sixth infusion pump, seventh infusion pump, circulation pump, trolley, electric trolley, detection pool 100, water quality analyzer 300, and detection probe 400 mentioned above are all devices with relatively mature existing technologies. Specific models can be selected according to actual needs. Meanwhile, the acid-resistant sodium filtration membrane concentration equipment, vapor recompression evaporator, first infusion pump, second infusion pump, third infusion pump, fourth infusion pump, fifth infusion pump, sixth infusion pump, seventh infusion pump, circulation pump, trolley, electric trolley, detection pool 100, and water quality analyzer 300 can be powered by their built-in power supply or by mains power. The specific power supply method should be selected according to the situation and will not be elaborated here.

[0039] In some embodiments, please refer to the appendix to the instruction manual. Figure 2-5 A water quality testing device for hydrochloric acid desorption wastewater treatment includes a directional guiding mechanism 500 that further includes a locking component 550. The locking component 550 includes a piston cylinder 551 fixedly connected to the outside of a positioning sleeve 530. A piston 552 is slidably connected inside the piston cylinder 551. A threaded rod 553, which is threadedly connected to the piston cylinder 551, is rotatably connected to the top of the piston 552. A liquid guide tube 554 is fixedly connected to and communicates with the bottom of the piston cylinder 551. One end of the liquid guide tube 554 extends through the inside of the positioning sleeve 530. An elastic liquid bladder 555, which is sleeved on the surface of a detection probe 400, is fixedly connected to and communicates with the other end of the liquid guide tube 554. The piston cylinder 551, the liquid guide tube 554, and the elastic liquid bladder 555 are all filled with water.

[0040] The positioning sleeve 530 has an annular cavity 531 on its inner side, and the elastic liquid bladder 555 is fixedly connected to the inside of the annular cavity 531, which can limit the position of the elastic liquid bladder 555.

[0041] The top of the threaded rod 553 is fixedly connected to a handle 556, and the corners of the handle 556 are rounded, which reduces the difficulty for the operator to rotate the threaded rod 553.

[0042] A guide rod 557 is fixedly connected to the top of the piston 552. The top of the guide rod 557 extends through the piston cylinder 551. The guide rod 557 is parallel to the axis of the threaded rod 553. There are two guide rods 557, which are symmetrically distributed on both sides of the axis of the threaded rod 553. This prevents the piston 552 from rotating with the threaded rod 553.

[0043] In this embodiment of the invention, after the detection probe 400 is connected to the water quality analyzer 300 through the positioning sleeve 530, the operator only needs to rotate the threaded rod 553 accordingly. The threaded rod 553 drives the piston 552 to approach the detection probe 400. At the same time, the piston 552 squeezes the water in the piston cylinder 551 into the liquid guide tube 554. The liquid guide tube 554 guides the water into the elastic liquid bladder 555. The elastic liquid bladder 555 is filled with water and expands, and firmly wraps around and locks the detection probe 400 along the annular cavity 531. This not only firmly locks the detection probe 400 inside the positioning sleeve 530, but also seals the gap between the detection probe 400 and the positioning sleeve 530, preventing water from entering the interior of the positioning sleeve 530.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
