[0002] The brine transport device is a device specifically used to transport brine. It is used to collect brine from salt lakes and transport it to terraces, where the brine evaporates naturally. In the sea salt brine industry, well brine industry, or lake salt industry, the brine transport device plays an important role. The brine transport device mainly consists of a brine pump, a transport pipeline, and detection equipment. Under working conditions, the brine transport device and the detection equipment are controlled and connected, and the collection and transportation of brine are continuous and stable. However, during the actual operation of the brine transport device, due to the high concentration of brine in the transport pipeline and the harsh environment in the transport pipeline, salt will form on the inner wall of the transport pipeline over time. This will, on the one hand, affect the accuracy of the detection results of the detection equipment; on the other hand, when there is a lot of salt in the transport pipeline, it will cause pipeline blockage, which will cause damage to the impeller or even the locking of the brine pump. This will not only reduce the annual production capacity, but also increase the maintenance cost of the brine transport device. Utility Model Content

[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a salt-coagulation-proof brine delivery device. The salt-coagulation-proof brine delivery device includes a brine delivery pump 8, which is provided with an inlet, an outlet, and an installation chamber; a liquid inlet pipeline 1, which is provided with a liquid inlet, a liquid outlet, an opening, and a branch pipe connected to the liquid inlet pipeline 1. The liquid inlet is used to introduce brine, and the liquid outlet is connected to the inlet of the brine delivery pump 8; a flushing portion, which includes a liquid storage portion and a first flushing pipeline 2 connected to the liquid storage portion. The first flushing pipeline 2 extends into the liquid inlet pipeline 1 through the opening and is connected to the liquid inlet pipeline 1; and a flow detection portion 3. The flow detection portion 3 has a measuring rod 31, which extends into the liquid inlet pipeline 1 through the branch pipe to detect the liquid flow in the liquid inlet pipeline 1. The flow detection portion 3 is control-connected to the flushing portion.

[0024] In the above technical solution, brine is passed into the liquid inlet pipe 1 from the liquid inlet. As time goes by, when the measuring rod 31 detects that the flow rate of brine in the liquid inlet pipe 1 is small, the flushing part can be started, and the water in the liquid storage part is passed into the liquid inlet pipe 1 through the first flushing pipe 2. In this way, the salt condensed on the inner wall surface of the liquid inlet pipe 1 can be cleaned, and the brine is passed to the inlet of the brine pump 8 from the liquid outlet. In this way, compared with the prior art, in this embodiment, by setting the first flushing pipe 2, the inner wall surface of the liquid inlet pipe 1 can be cleaned. On the one hand, the blockage of the liquid inlet pipe 1 can be avoided, thereby avoiding the locking of the brine pump 8, so as to avoid the reduction of annual production capacity, and thus reducing the maintenance cost of the anti-salt brine delivery device; on the other hand, the accuracy of the detection result of the flow detection part 3 can also be improved.

[0025] Specifically, in an embodiment of the present invention, the liquid inlet of the liquid inlet pipeline 1 is connected to the salt lake, and the outlet of the brine pump 8 is connected to the terraced field. In this way, the brine will enter the salt field from the liquid inlet pipeline 1 through the brine pump 8, and the brine will evaporate naturally in the salt field.

[0026] Specifically, in the embodiment of the present invention, the liquid medium in the liquid storage part can be clean water or low-concentration brine.

[0027] Specifically, in the embodiment of the present invention, the material of the measuring rod 31 is stainless steel.

[0028] Specifically, in an embodiment of the present invention, the flow detection part 3 also includes a measuring head, which is used to detect the flow rate in the liquid inlet pipeline 1. The measuring head is fixedly connected to the measuring rod 31. The measuring head is an end head or a conduit made of insulating material. A pair of electrodes is installed on the measuring head. Except for the measuring head, the other parts of the measuring rod 31 are insulated from the brine in the liquid inlet pipeline 1. The flow detection part 3 also includes an excitation system, which includes an excitation coil and an iron core. The excitation system is insulated and sealed and fixed to the measuring rod 31. The function of the excitation system is to generate a working magnetic field. The flow detection part 3 also includes a converter and a junction box 32. The junction box 32 is fixedly connected to the measuring rod 31, and the junction box 32 is arranged at the end of the measuring rod 31 away from the liquid inlet pipeline 1. The junction box 32 is electrically connected to the converter. The specific structure of the flow detection part 3 can refer to the existing technology and will not be repeated here.

[0029] Specifically, in the embodiment of the present invention, the detection principle of the flow detection part 3 is: when the conductive fluid passes vertically through the working magnetic field of the measuring rod 31 (when the converter provides excitation current to the excitation coil, a working magnetic field is generated in the excitation system formed by the excitation coil), it is equivalent to the conductive fluid cutting the magnetic lines of force in the working magnetic field. According to Faraday's law of electromagnetic induction, an induced electromotive force will be generated at both ends of the conductive fluid. The induced electromotive force is detected by the electrodes on the measuring head. The magnitude of the induced electromotive force is proportional to the magnetic induction intensity B, the distance L between the two poles and the average flow velocity of the fluid, that is, E=B·L·V·K, wherein E represents the induced electromotive force, B represents the magnetic induction intensity, L represents the distance between the two electrodes, V represents the flow velocity flowing through the flow velocity sensor (that is, representing the particle flow velocity of the measured point in the liquid inlet pipeline 1), and K is a coefficient, which is converted into the coefficient of the average flow velocity according to the distribution position of the measuring rod 31 in the liquid inlet pipeline 1.

[0030] like Figure 2 As shown, in the embodiment of the present invention, the anti-salt brine transport device also includes a first valve 4, which is sleeved on the outer periphery of the measuring rod 31, the first valve 4 is slidably fitted with the measuring rod 31, and the branch pipe is slidably fitted with the measuring rod 31, and along the axial direction of the measuring rod 31, the first valve 4 has a first end and a second end that are relatively arranged.

[0031] In the above technical solution, when the measuring rod 31 needs to be replaced, the measuring rod 31 is pulled above the first valve 4 and the first valve 4 is closed. In this way, the brine in the liquid inlet pipeline 1 can be prevented from overflowing from the first valve 4.

[0032] Specifically, in the embodiment of the present invention, the first valve 4 is a ball valve.

[0033] like Figure 2As shown, in the embodiment of the present invention, the first end of the first valve 4 is provided with a first connecting flange 41, and the anti-salt brine transport device also includes a plurality of first locking members; a second connecting flange 5, the second connecting flange 5 is connected to the branch pipe, and the first connecting flange 41 is connected to the second connecting flange 5 through a plurality of first locking members.

[0034] In the above technical solution, by setting the first connecting flange 41, the first end of the first valve 4 can be connected to the second connecting flange 5 through multiple first locking members, and then connected to the branch pipe through the second connecting flange 5. In this way, the connection between the first end of the first valve 4 and the branch pipe can be realized.

[0035] Specifically, in an embodiment of the present invention, the first locking member is a screw.

[0036] Specifically, in the embodiment of the present invention, the second connecting flange 5 is connected to the branch pipe by welding.

[0037] like Figure 2 As shown, in the embodiment of the present invention, the second end of the first valve 4 is provided with a third connecting flange 42, and the anti-salt brine delivery device also includes a sealing member 61, which is located on the outer periphery of the measuring rod 31, and the sealing member 61 is sealed with the measuring rod 31; a plurality of second locking members; a fourth connecting flange 6, the fourth connecting flange 6 is connected to the sealing member 61, and the third connecting flange 42 and the fourth connecting flange 6 are connected by a plurality of second locking members.

[0038] In the above technical solution, by setting the third connecting flange 42, the second end of the first valve 4 can be connected to the fourth connecting flange 6 through multiple second locking parts, and then connected to the sealing member 61 through the fourth connecting flange 6. In this way, the sealing member 61 can be fixed to the outer periphery of the measuring rod 31.

[0039] Specifically, in an embodiment of the present invention, the second locking member is a screw.

[0040] Specifically, the seal 61 is a head seal, and the shape of the seal 61 is annular, and the seal 61 and the measuring rod 31 are interference fit. When the measuring rod 31 needs to be removed from the seal 61, the measuring rod 31 can be removed by applying lubricant or using a pin puller.

[0041] like Figure 2 As shown, in the embodiment of the present invention, the flow detection part 3 further includes a handle 33 , which is connected to the outer periphery of the measuring rod 31 , and is located at the end of the measuring rod 31 away from the liquid inlet pipeline 1 .

[0042] Through the above arrangement, the handle 33 can save effort, so that the installation and removal of the measuring rod 31 can be more convenient.

[0043] Preferably, in the embodiment of the present invention, there are two handles 33 .

[0044] like Figure 2 As shown, in the embodiment of the present invention, a second valve 7 is provided on the first flushing pipeline 2, and the second valve 7 can be opened and closed.

[0045] In the above technical solution, by providing the second valve 7, the brine in the liquid inlet pipeline 1 can be prevented from flowing back into the flushing part.

[0046] Specifically, in the embodiment of the present invention, the second valve 7 is a check valve. The working principle of a check valve is to use the pressure difference of the fluid to control the opening and closing of the valve flap. When the fluid flows in the forward direction along the pipeline, that is, the liquid in the liquid storage portion flows from the first flushing pipeline 2 through the opening into the liquid inlet pipeline 1, the fluid pressure will push open the valve flap, allowing the fluid to pass smoothly. When the fluid flows in the reverse direction, that is, the liquid in the liquid inlet pipeline 1 flows back through the opening into the first flushing pipeline 2, the valve flap automatically closes under the action of the fluid pressure and its own weight, preventing the fluid from flowing back.

[0047] like Figure 2 As shown, in an embodiment of the present invention, the flushing portion further includes a second flushing pipeline, one end of the second flushing pipeline is connected to the inlet of the brine pump 8, and the other end of the second flushing pipeline is connected to the liquid storage portion; the flushing portion further includes a third flushing pipeline, one end of the third flushing pipeline is connected to the outlet of the brine pump 8, and the other end of the third flushing pipeline is connected to the liquid storage portion.

[0048] In the above technical solution, the liquid in the liquid storage part flows to the inlet of the brine pump 8 through the second flushing pipeline, and the liquid in the liquid storage part flows to the outlet of the brine pump 8 through the third flushing pipeline. In this way, the condensed salt in the brine pump 8 can be cleaned, thereby preventing the impeller from being damaged or even the brine pump 8 from locking.

[0049] like Figure 2 As shown, in the embodiment of the present invention, water pumps are provided on the first flushing pipeline 2, the second flushing pipeline and the third flushing pipeline.

[0050] Through the above-mentioned setting, the water pump on the first flushing pipeline 2 can pump the liquid in the liquid storage part from the first flushing pipeline to the liquid inlet pipeline 1, the water pump on the second flushing pipeline can pump the liquid in the liquid storage part from the second flushing pipeline to the inlet of the brine pump 8, and the water pump on the third flushing pipeline can pump the liquid in the liquid storage part from the third flushing pipeline to the outlet of the brine pump 8.

[0051] In one embodiment, the first flushing pipeline, the second flushing pipeline and the third flushing pipeline are all provided with a high-level water tank or a high-pressure water source.

[0052] Specifically, in the embodiment of the present invention, the flow detection unit 3 is connected to the water pump control of the first flushing pipeline 2 .

[0053] In one embodiment, when the brine flow rate in the liquid inlet pipeline 1 is less than a certain set value, the liquid inlet pipeline 1 can be flushed by manually opening the water pump of the first flushing pipeline 2 to avoid salt accumulation on the inner wall of the liquid inlet pipeline 1.

[0054] In one embodiment, the control connection between the flow detection part 3 and the water pump of the first flushing pipeline 2 can refer to the existing technology.

[0055] like Figure 2 As shown, in the embodiment of the present invention, the inner wall surface of the liquid inlet pipeline 1 is coated with a hydrophobic material to form a smooth surface.

[0056] Through the above arrangement, the probability of salt deposition on the inner wall surface of the liquid inlet pipeline 1 can be reduced.

[0057] Specifically, in the embodiment of the present invention, the hydrophobic material may be polytetrafluoroethylene (PTFE) or a silicone coating.

[0058] Specifically, in the embodiment of the present invention, the inner wall surface of the liquid inlet pipe 1 is cleaned, and the anti-corrosion paint layer with serious local contamination is polished with sandpaper to make the inner wall surface clean and free of dust, rust, oil stains and other pollutants. Then, a surface treatment agent is used to treat the wall surface to be painted. After brushing, it is naturally dried and the prepared paint is sprayed with a sprayer. The parts that are missed or over-painted are carefully checked and adjusted in time to ensure that the overall thickness of the paint is uniform. After brushing, a paint baking lamp is used for auxiliary heating and curing until the paint film is completely hardened and formed, and then anti-crystallization and filling treatment are carried out. The treatment method uses brushing to infiltrate the surface of the paint coating. The treatment time is at least once every 3 days to ensure that the coating surface is moistened. It is completed after 2 times. Note that bumps and scratches should be prevented during this process, and it should be covered and protected when not in use for a long time.

[0059] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, the brine pump 8 includes a pump body 87, the interior of the pump body 87 forms an installation chamber; an impeller 89, the impeller 89 is arranged in the installation chamber; a pump cover 91, the pump cover 91 is arranged at one end of the pump body 87; the tail cover 82 is provided with a drainage hole, and the tail cover 82 is arranged at the other end of the pump body 87; at least one of the inner wall of the installation chamber, the inner wall of the pump cover 91, the surface of the impeller 89, and the inner wall surface of the drainage hole is provided with a hydrophobic material to form a smooth surface.

[0060] Through the above arrangement, the probability of salt accumulation in the brine pump 8 can be reduced.

[0061] Specifically, in the embodiment of the present invention, the brine pump 8 also includes a pulley 81, a pump shaft 83, a stopper sleeve 84, a bearing 85, a front cover 86, a screw plug 88, an impeller nut 90, a stuffing gland 92, a stuffing 93, a sleeve 94, an impeller nut washer 95, a bearing body 96 and a stuffing seat 97. The specific structure and assembly relationship of the brine pump 8 can refer to the existing technology and will not be repeated here.

[0062] Specifically, in the embodiment of the present invention, the coating process of the hydrophobic material inside the brine pump 8 is as follows: after the brine pump 8 is stopped, the anchor bolts are removed, the pump cover 91 is opened, and the impeller 89, the pulley 81, the bearing body 96, the shaft sleeve 94, the stuffing gland 92 and the tail cover 82 are removed. First, clean the workpiece, then use a surface treatment agent to treat the surface of the workpiece to be coated, brush it and let it dry naturally. Then, paint is applied by brushing, such as Figure 1 As shown, the mating surfaces of the pump cover 91 and the pump body, the cylindrical surface of the pump cover stop, and the mating surfaces of the tail cover 82 and the pump body do not require painting. However, the pump cover 91, the surface of the impeller 89, the drainage holes of the tail cover 82, and the internal flow surfaces of the brine pump 8 all require painting. These flow surfaces include the surface of the impeller 89, the inner wall of the volute, the inner wall of the tail cover 82, and the inner wall of the pump cover 91. After the paint is cured using auxiliary heat, it is filled with a crystallizing agent in the same manner as the liquid inlet pipeline 1. After a final inspection, the brine pump 8 is assembled and put into operation.

[0063] Specifically, if Figure 3 As shown, in the embodiment of the present invention, clean water or low-concentration brine is flushed into the liquid inlet pipe 1 for cleaning, and the judgment module delays the judgment parameter to determine whether it has returned to normal. The time t1 between the end of the cleaning and the end of the last cleaning is recorded as the time when the driving module automatically starts cleaning. This time can be continuously corrected through delayed judgment. If it is abnormal, the alarm module is triggered, and it is determined to be a fault type of the brine delivery pump 8. The judgment result, i.e., the current, voltage, flow and vibration conditions, is output to assist personnel in solving the problem. Once the anti-salt brine delivery device starts the flushing part and eliminates salt after normal operation for a period of time, it begins to slowly form salt again. The flow detection part 3 signal feedback flow is too small. At this time, the time t2 of the last flushing part flushing can be directly used, i.e., the running time of the brine delivery pump 8. If the salt in the liquid inlet pipe 1 and the brine delivery pump 8 is still not eliminated, the flushing time of the flushing part is extended. Finally, time t1 and t2, corresponding to the brine transportation time and cleaning time of the system, are repeated continuously to ensure the distribution capacity requirements of the anti-salting brine delivery device under specific operating conditions (flow resistance characteristics of the brine delivery pump 8, climatic conditions, brine concentration and viscosity properties, etc.).

[0064] Specifically, in the embodiment of the present invention, the anti-salt brine delivery device monitors the operating parameters of the brine delivery pump 8, mainly including pressure, flow, current, voltage and vibration. The lift formula of the brine delivery pump 8 is: Among them, H is the head of the brine pump 8, in meters; p1, p2 are the absolute pressures at the inlet and outlet of the brine pump 8 (pressure sensors are provided at the inlet and outlet of the brine pump 8 to detect the liquid pressure at the inlet and outlet of the brine pump 8), in Pascals; ρ is the liquid density, in kilograms per cubic meter; g is the acceleration due to gravity, which is 9.81m / S 2 ; Z1, Z2 is the height difference between the inlet and outlet pressure gauges of the brine pump 8, in meters; v1, v2 is the liquid flow rate at the inlet and outlet of the brine pump 8, in meters per second.

[0065] Specifically, in the embodiment of the present invention, the anti-salt brine delivery device can monitor the operating status of the brine delivery pump 8, calculate the power and operating efficiency of the pump shaft 83 of the brine delivery pump 8, the power of the pump shaft 83 of the brine delivery pump 8, calculate the motor input active power by current and voltage, and then calculate the transmission efficiency and motor efficiency between the impeller 89 drive shaft and the motor input end. The transmission efficiency and motor efficiency generally take fixed values. Therefore, the motor input active power calculation formula is: Among them, U is the AC motor voltage; I is the motor current; The real-time operating efficiency formula of the brine pump 8 is: Where Q is the volume flow rate in the liquid inlet pipeline 1; N is the pump shaft power; and H is the head of the brine pump 8. Therefore, the operating status of the anti-salt brine delivery device can be determined based on the real-time operating efficiency formula of the brine pump 8 and the power of the pump shaft 83.

[0066] Specifically, in the embodiment of the present utility model, Figure 4 This is a graph showing the flow rate of the inlet pipeline 1 and the head of the brine pump 8 in the anti-salting brine delivery device. The horizontal axis is the volume flow rate Q in the inlet pipeline 1, and the vertical axis is the head H of the brine pump 8. There are two operating points A and B (corresponding to curves D and C, respectively). The head at point A is H0 and the volume flow rate is Q0. The head at point B is H1 and the volume flow rate is Q1. When the degree of salt accumulation in the inlet pipeline 1 increases, the resistance in the inlet pipeline 1 increases, and the operating point moves from A to B (from R to R'). B is the key to triggering the start of the flushing unit. Curve E is the power curve of the brine pump 8. Accordingly, the brine pump 8 operates between the operating conditions of points A and B. The parameters of the electrical signals (current, voltage, and vibration) are all stable values ​​or values ​​within a small fluctuation range. Comparison is made to see whether they are lower or higher than the parameter thresholds for normal operation. The auxiliary judgment module then determines the salt accumulation status in the inlet pipeline 1 and the brine pump 8.

[0067] Specifically, in the embodiments of the present invention, the control steps and control principles of the above-mentioned anti-salt brine delivery device can refer to the existing technology, and this application mainly protects the structure of the anti-salt brine delivery device.

[0068] Specifically, in the embodiment of the present invention, a method for preventing salt deposition by using hydrophobic materials inside the integrated liquid inlet pipeline 1 is combined with a monitoring and control operation method: through continuous signal control feedback, the most reasonable cleaning interval and cleaning time of the anti-salt brine delivery device to ensure the normal operation of the delivery system are finally found, and clean water is flushed in real time, and the operating status of the brine delivery pump 8 is constantly reflected, including the efficiency and power of the brine delivery pump 8. In this way, on the one hand, the smooth operation of the anti-salt brine delivery device can be guaranteed, salt will not form on the inner wall of the liquid inlet pipeline 1, and the brine delivery pump 8 will continue to operate efficiently. On the other hand, it can reduce personnel maintenance costs, simplify the control of the anti-salt brine delivery device, and improve efficiency.

[0069] Specifically, in an embodiment of the present invention, the flushing part also includes a fourth flushing pipeline, one end of the fourth flushing pipeline is connected to the liquid storage part, and the other end of the fourth flushing pipeline extends into the liquid inlet pipeline 1 to flush the surface of the measuring rod 31, thereby preventing salt from forming on the surface of the measuring rod 31.

[0070] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: brine is passed into the liquid inlet pipeline from the liquid inlet, and as time goes by, when the measuring rod detects that the flow rate of brine in the liquid inlet pipeline is small, the flushing part can be started, and the water in the liquid storage part is passed into the liquid inlet pipeline through the first flushing pipeline. In this way, the salt condensed on the inner wall surface of the liquid inlet pipeline can be cleaned, and the brine is passed to the inlet of the brine pump from the liquid outlet. In this way, compared with the prior art, in this embodiment, by setting the first flushing pipeline, the inner wall surface of the liquid inlet pipeline can be cleaned. On the one hand, the phenomenon of blockage of the liquid inlet pipeline can be avoided, thereby avoiding the phenomenon of locking of the brine pump, avoiding the phenomenon of reducing annual production capacity, and further reducing the maintenance cost of the anti-salt brine delivery device; on the other hand, the accuracy of the detection result of the flow detection part can also be improved.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
