Description

Technical Field

[0001] This utility model relates to the field of washing technology, specifically to a washing liquid temperature control device for reverse washing. Background Technology

[0002] In industrial fields such as mineral processing and chemical separation, settling tanks are key equipment for solid-liquid separation. They use the principle of gravity settling to make solid particles in suspension sink, thereby obtaining clarified liquid and underflow slurry. In order to improve the purity of solid products or recover valuable components, the concentrated slurry at the bottom of the settling tank needs to be washed. That is, through a reverse washing process, the washing liquid flows upward from the bottom of the settling tank, fully contacts the sinking solid particles, and replaces and removes impurities or soluble substances attached to the particle surface.

[0003] The effectiveness of reverse washing directly affects the quality of the final product, and the temperature of the washing liquid is a key control parameter: too low a temperature will cause the viscosity of the washing liquid to increase and the fluidity to decrease, which will not only prolong the washing time but also reduce the efficiency of impurity replacement; too high a temperature may damage the structural stability of solid particles or cause the dissolution and loss of target components (such as certain heat-sensitive minerals or chemicals). In addition, fluctuations in the temperature of the washing liquid will cause local convection instability in the settling tank, interfere with the particle settling pattern, and affect the consistency of the separation effect.

[0004] In traditional settling tank washing systems, the temperature control of the washing liquid often uses external heat exchange equipment (such as plate heat exchangers). The cooled or heated washing liquid is transported to the settling tank through pipelines. During the transport of the washing liquid from the heat exchange equipment to the settling tank, heat loss or absorption can easily occur due to the ambient temperature difference, causing the actual temperature of the washing liquid entering the settling tank to deviate from the set value. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model solve the technical problem that in the traditional settling tank washing system of the prior art, the washing liquid temperature control is mostly achieved by using an external heat exchange device. The cooled or heated washing liquid is transported to the settling tank through pipelines. During the transportation of the washing liquid from the heat exchange device to the settling tank, heat loss or absorption is easily caused by the ambient temperature difference, resulting in the actual temperature of the washing liquid entering the settling tank deviating from the set value.

[0007] A control box, the upper end of which is provided with a sealing buckle cover;

[0008] A sealed thermostatic assembly is disposed within the control box;

[0009] A liquid diversion assembly is disposed inside the control box;

[0010] The sealed thermostatic assembly includes a temperature control tube;

[0011] The temperature control tube is coiled in a serpentine shape inside the control box, with both ends of the temperature control tube extending out from the same side of the control box. The two ends of the temperature control tube are respectively provided with a liquid inlet and a liquid outlet. A sealing ring is provided at the lower end of the sealing cover, and a rotating cavity is opened on the upper end face of the sealing cover. A locking shaft is provided inside the rotating cavity, and a locking plate is provided at the bottom of the locking shaft. The locking plate is engaged with the control box.

[0012] For example, the sealing and temperature-controlled assembly provided in at least one embodiment of this utility model also includes a limiting ring;

[0013] The limiting ring is movably fitted on the locking shaft and embedded inside the rotating cavity. The locking plate has an engagement groove that fits against the inner wall of the control box.

[0014] According to another aspect, at least one embodiment of the present invention also provides a liquid diversion assembly, including a liquid inlet shroud;

[0015] The liquid inlet hood is disposed on the upper end face of the sealing buckle cover, and the liquid inlet hood is connected to the sealing buckle cover. The inner side wall of the liquid inlet hood is provided with a diversion strip, and the inner bottom surface of the control box is provided with a liquid outlet, and a liquid outlet hood is provided on the liquid outlet.

[0016] For example, the liquid diversion assembly provided in at least one embodiment of this utility model also includes a liquid outlet pipe;

[0017] The liquid outlet pipe is located at the lower end of the liquid outlet hood and is connected to the liquid outlet hood. The liquid outlet pipe is equipped with a spiral guide plate inside, and the spiral guide plate has a spiral structure.

[0018] As a further technical solution, the outer wall of the limiting ring is provided with a positioning pin, which is inserted into the interior of the rotating cavity.

[0019] As a further technical solution, a screw is provided at the top of the locking shaft, and the screw is located at the upper end of the sealing buckle cover.

[0020] As a further technical solution, a sealing gasket is provided on the lower end face of the sealing buckle cover, and the sealing gasket is located on the outer contour of the sealing ring.

[0021] As a further technical solution, the upper surface of the control box has a notch, and the sealing ring is sealed and inserted into the notch.

[0022] The beneficial effects of this utility model are as follows:

[0023] In this invention, the serpentine spiral temperature control tube increases the contact area and contact time with the washing liquid, resulting in more thorough and uniform heat exchange and effectively avoiding localized temperature deviations. Simultaneously, the device is directly integrated into the washing liquid delivery path, reducing pipeline transmission losses typical of external equipment. This ensures that the temperature of the washing liquid entering the settling tank is highly consistent with the set value, thereby stabilizing impurity replacement efficiency and preventing product purity instability caused by temperature fluctuations. The sealing cap, through the insertion and engagement of the sealing ring with the control box notch, the secondary protection of the sealing gasket, and the meshing and fixing of the locking plate with the inner wall of the control box, forms a multi-layered sealing structure, significantly improving the overall sealing performance of the device and effectively preventing material waste caused by washing liquid leakage. It also prevents external contaminants from entering the washing liquid, ensuring the cleanliness of the washing process, making it particularly suitable for mineral processing or chemical separation scenarios with high purity requirements.

[0035] like Figures 1-3 As shown, it illustrates a washing liquid temperature control device for reverse washing according to an embodiment of the present invention, including...

[0036] Control box 1, with a sealing buckle cover 2 at the upper end of the control box 1;

[0037] Sealed thermostatic component 3 is installed inside control box 1;

[0038] Liquid diversion assembly 4 is located inside control box 1;

[0039] The sealed thermostatic assembly 3 includes a temperature control tube 3-1;

[0040] The temperature control tube 3-1 is coiled in a serpentine shape inside the control box 1. Both ends of the temperature control tube 3-1 extend out of the same side of the control box 1. The two ends of the temperature control tube 3-1 are respectively provided with liquid inlet 3-2 and liquid outlet 3-3. The lower end of the sealing cover 2 is provided with a sealing ring 3-4. The upper end face of the sealing cover 2 has a rotating cavity 3-5. The rotating cavity 3-5 is provided with a locking shaft 3-6. The bottom of the locking shaft 3-6 is provided with a locking piece 3-7. The locking piece 3-7 is engaged with the control box 1.

[0041] In some examples, the control box 1, which serves as the main frame of the device, is made of corrosion-resistant material to adapt to the working environment of the washing liquid.

[0042] The core of the sealed thermostatic component 3 is the temperature control tube 3-1. The temperature control tube 3-1 is made of a material with good thermal conductivity and is coiled in a serpentine shape inside the control box 1. This serpentine structure can increase the flow time of the washing liquid in the temperature control tube 3-1, thereby achieving better temperature control. The two ends of the temperature control tube 3-1 extend out of the same side of the control box 1 and are respectively set as the liquid inlet 3-2 and the liquid outlet 3-3. The washing liquid enters the temperature control tube 3-1 from the liquid inlet 3-2 and is discharged from the liquid outlet 3-3 after temperature adjustment.

[0043] Through the synergistic effect of the above components, the washing liquid temperature control device for reverse washing can achieve effective temperature control and stable delivery of the washing liquid, meeting the working requirements of reverse washing.

[0044] refer to Figure 1 and Figure 3 In some embodiments, the sealing thermostatic assembly 3 further includes a limiting ring 3-8;

[0045] The limiting ring 3-8 is movably mounted on the locking shaft 3-6. The limiting ring 3-8 is embedded inside the rotating cavity 3-5. The locking plate 3-7 has a meshing groove 3-9, which fits against the inner wall of the control box 1.

[0046] In some examples, a limiting ring 3-8 is movably mounted on the locking shaft 3-6, and the limiting ring 3-8 is embedded inside the rotating cavity 3-5.

[0047] like Figures 1-3As shown, on the other hand, this utility model also provides a liquid diversion assembly 4, including a liquid inlet hood 4-1;

[0048] The liquid inlet cover 4-1 is located on the upper end face of the sealing buckle cover 2. The liquid inlet cover 4-1 is connected to the sealing buckle cover 2. The inner side wall of the liquid inlet cover 4-1 is provided with a diversion strip 4-2. The inner bottom surface of the control box 1 is provided with a liquid outlet 4-3. A liquid outlet cover 4-4 is provided on the liquid outlet 4-3.

[0049] The liquid diversion assembly 4 also includes an outlet pipe 4-5;

[0050] The liquid outlet pipe 4-5 is located at the lower end of the liquid outlet hood 4-4. The liquid outlet pipe 4-5 is connected to the liquid outlet hood 4-4. The liquid outlet pipe 4-5 is equipped with a spiral guide plate 4-6, which has a spiral structure.

[0051] In some examples, the liquid diversion assembly 4 includes an inlet hood 4-1, a diversion strip 4-2, an outlet 4-3, an outlet hood 4-4, an outlet pipe 4-5, and a spiral guide plate 4-6. The inlet hood 4-1 is located on the upper end face of the sealing cover 2 and is connected to the sealing cover 2. The washing liquid can enter the device through the inlet hood 4-1. The diversion strip 4-2 is provided on the inner side wall of the inlet hood 4-1. The diversion strip 4-2 can divert the incoming washing liquid, so that the washing liquid enters the subsequent structure more evenly.

[0052] The bottom inner surface of the control box 1 is provided with a liquid outlet 4-3. A liquid outlet cover 4-4 is installed on the liquid outlet 4-3. The lower end of the liquid outlet cover 4-4 is connected to a liquid outlet pipe 4-5. The liquid outlet pipe 4-5 and the liquid outlet cover 4-4 are connected. The treated washing liquid enters the liquid outlet pipe 4-5 through the liquid outlet 4-3 and the liquid outlet cover 4-4, and is finally discharged from the liquid outlet pipe 4-5. A spiral guide plate 4-6 is provided inside the liquid outlet pipe 4-5. The spiral guide plate 4-6 has a spiral structure. Its function is to guide the washing liquid to flow spirally in the liquid outlet pipe 4-5, reduce flow resistance, and at the same time, it can further mix the washing liquid to a certain extent.

[0053] For example, such as Figure 3 As shown, a positioning pin 5 is provided on the outer wall of the limiting ring 3-8, and the positioning pin 5 is inserted into the interior of the rotating cavity 3-5.

[0054] In some examples, the outer wall of the limiting ring 3-8 is provided with a positioning pin 5, which is inserted into the interior of the rotating cavity 3-5. This structural design can limit the axial movement of the locking shaft 3-6 and ensure the stability of the locking operation.

[0055] For example, such as Figure 3 As shown, a screw 6 is provided on the top of the locking shaft 3-6, and the screw 6 is located at the upper end of the sealing cover 2.

[0056] In some examples, the upper end face of the sealing cover 2 has a rotating cavity 3-5, and a locking shaft 3-6 is provided inside the rotating cavity 3-5. A turning knob 6 is installed on the top of the locking shaft 3-6. The turning knob 6 is located at the upper end of the sealing cover 2, which makes it convenient for the operator to rotate the locking shaft 3-6. A locking plate 3-7 is connected to the bottom of the locking shaft 3-6. A meshing groove 3-9 is opened on the locking plate 3-7. The meshing groove 3-9 fits against the inner side wall of the control box 1. By rotating the locking shaft 3-6, the locking plate 3-7 can be meshed with the control box 1, thereby firmly fixing the sealing cover 2 to the control box 1.

[0057] For example, such as Figure 2 As shown, a sealing gasket 7 is provided on the lower end face of the sealing cover 2, and the sealing gasket 7 is located on the outer contour of the sealing ring 3-4.

[0058] In some examples, a sealing gasket 7 is provided on the lower end face of the sealing cover 2, located at the outer contour of the sealing ring 3-4, which further enhances the sealing performance of the device.

[0059] For example, such as Figure 1 As shown, the upper surface of the control box 1 has a notch 8, and the sealing ring 3-4 is sealed and inserted into the notch 8.

[0060] In some examples, the upper surface of the control box 1 has a notch 8 for sealing connection with the sealing cover 2. The lower end of the sealing cover 2 is provided with a sealing ring 3-4, which matches the notch 8 at the upper end of the control box 1. The two are sealed and inserted together, which can effectively prevent the washing liquid from leaking.

[0061] During operation, the working principle of this reverse washing liquid temperature control device is based on the synergistic effect of fluid transmission, temperature regulation, and sealing protection. The specific process is as follows:

[0062] 1. Washing liquid input and diversion

[0063] The washing liquid to be treated first enters the device through the inlet hood 4-1. The diversion strip 4-2 on the inner wall of the inlet hood 4-1 disperses the fluid into multiple branches, so that the washing liquid flows evenly into the control box 1. This diversion design can avoid uneven temperature regulation caused by excessive local flow, and at the same time reduce the impact of the fluid on the internal structure of the device.

[0064] 2. Temperature regulation process

[0065] The washing liquid entering the control box 1 comes into full contact with the serpentine temperature control tube 3-1. A constant temperature medium (such as hot water, cold water, or heat transfer oil) can be introduced into the temperature control tube 3-1 to regulate the temperature of the washing liquid through heat exchange.

[0066] If heating is required, a high-temperature medium is introduced into the temperature control tube 3-1, and the heat is transferred to the washing liquid through the tube wall;

[0067] If cooling is required, a low-temperature medium is introduced into the temperature control tube 3-1 to absorb the heat from the washing liquid.

[0068] The serpentine structure extends the contact time and contact area between the washing liquid and the temperature control tube 3-1, ensuring sufficient and stable temperature regulation.

[0069] 3. Sealing and leak-proof mechanism

[0070] The control box 1 and the sealing cover 2 achieve initial sealing through the sealing ring 3-4 and the notch 8. The sealing gasket 7 further enhances the sealing performance at the joint to prevent the washing liquid from leaking. When the locking shaft 3-6 is rotated, the locking plate 3-7 at the bottom engages with the inner wall of the control box 1 through the meshing groove 3-9, which firmly fixes the sealing cover 2. At the same time, the limiting ring 3-8 and the positioning pin 5 restrict the axial displacement of the locking shaft 3-6 to ensure the stability of the sealing state.

[0071] 4. Washing liquid output and drainage

[0072] The temperature-regulated washing liquid is collected at the bottom of the control box 1, enters the liquid outlet 4-4 through the liquid outlet 4-3, and then flows into the liquid outlet pipe 4-5. The spiral guide plate 4-6 in the liquid outlet pipe 4-5 guides the fluid to flow in a spiral shape, which reduces turbulence and resistance and makes the output more stable. On the other hand, the spiral motion further mixes the washing liquid to ensure that the temperature is uniform during output.

[0073] The device achieves precise temperature control of the washing liquid for reverse washing through a continuous process of diversion, temperature control, sealing, and diversion, while ensuring the sealing and stability of the fluid during transmission, thus meeting the stringent temperature requirements of the reverse washing process.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
