Description

Technical Field

[0001] This utility model belongs to the field of chemical equipment technology, and in particular relates to a solid-liquid separation tank for chemical mother liquor. Background Technology

[0002] In chemical production processes, mother liquor is an important product of chemical reactions or extraction processes. Its composition is complex and often contains a large number of solid particles, suspended matter and dissolved substances. Solid-liquid separation of mother liquor is an indispensable step in order to ensure the normal operation of subsequent processes and the quality of products.

[0003] However, existing solid-liquid separation tanks, especially those designed for chemical mother liquor, usually have built-in filter cartridges to achieve solid-liquid separation, trapping solid particles while allowing mother liquor to pass through. In practical applications, due to the varying sizes of solid particles in chemical mother liquor, these particles easily accumulate in the pores of the filter cartridge, causing blockage. As the blockage worsens, the permeability of the filter decreases sharply, severely affecting the separation efficiency and the flow rate of the mother liquor. Utility Model Content

[0022] In this embodiment, tank 1 serves as the main body of the entire separation device. Filter cartridge 2 is located inside tank 1 and connected to the first motor 7 via rotating shaft 6. Its main function is to filter and separate solid particles from the chemical mother liquor.

In summary, this chemical mother liquor solid-liquid separation tank, through the innovative design of the rotatable filter cartridge 2, air jet pipe 8, and air supply mechanism, effectively solves the problems of easy clogging and low separation efficiency of traditional separation tanks, and improves the efficiency and effect of chemical mother liquor treatment.

[0023] In a further preferred embodiment of this utility model, the air supply mechanism includes: a fan 9 fixed on the tank 1, the air outlet of the fan 9 being connected to the jet pipe 8 via an air outlet pipe 10; a filter box 11 disposed on the tank 1 for pre-filtering the air entering the fan 9, the air outlet of the filter box 11 being connected to the air inlet of the fan 9 via a connecting pipe; a plurality of filter plates 12 disposed in the filter box 11 for filtering air impurities; and an air inlet pipe 13 fixedly connected to the filter box 11 for guiding air into the filter box 11.

[0024] In this embodiment, the air supply mechanism is designed in detail and with optimization, specifically including components such as a fan 9, an air outlet pipe 10, a filter box 11, a filter plate 12, and an air inlet pipe 13. The coordinated operation of these components not only provides a stable air source for the jet pipe 8 but also ensures the quality of the air entering the jet pipe, thereby further improving the solid-liquid separation effect and the reliability of the equipment. The fan 9 is fixed to the tank 1, serving as the power source for the entire air supply mechanism. Its outlet end is connected to the jet pipe 8 through the air outlet pipe 10, providing the required high-pressure airflow to the jet pipe. The stable operation of the fan 9 ensures that the jet pipe 8 can continuously and effectively spray airflow to clear the filter cartridge 2 and prevent filter pore blockage. Simultaneously, by adjusting the output power of the fan, the intensity and frequency of the jet can be flexibly controlled to adapt to the separation requirements under different working conditions. The air outlet pipe 10 connects the air outlet end of the fan 9 to the jet pipe 8, responsible for delivering the high-pressure airflow generated by the fan to the jet pipe. The design of the air outlet pipe 10 ensures smooth airflow transmission, reduces energy loss, and improves jet efficiency. Meanwhile, its material and connection method must also meet the requirements of corrosion resistance and sealing in the chemical mother liquor treatment process; the filter box 11 is set on the tank 1 as a pre-filtration device for air, and its outlet end is connected to the inlet end of the blower 9 through a connecting pipe. The filter box is equipped with multiple filter plates 12 for filtering impurities in the air; the combined use of the filter box 11 and filter plates 12 effectively removes dust, particulate matter and other impurities in the air, preventing these impurities from entering the jet pipe 8 and filter cartridge 2 with the airflow, thereby protecting the normal operation of the equipment and extending its service life; the filter plate 12 is a key filtration element in the filter box 11, usually made of porous material, which can trap small particulate matter in the air; in summary, this air supply mechanism, through the close cooperation of components such as the blower 9, the outlet pipe 10, the filter box 11, the filter plates 12 and the inlet pipe 13, provides a stable and clean air source for the jet pipe 8, effectively solving the problem of easy clogging of the filter cartridge, and improving the efficiency and quality of solid-liquid separation.

[0025] In a further preferred embodiment of the present invention, a first auger 14 is provided inside the feed pipe 3, and a second motor 15 is fixedly installed on the feed pipe 3. The output shaft of the second motor 15 is fixedly connected to the first auger 14 through a coupling.

[0026] In this embodiment, the feed pipe 3 has been optimized by introducing two key components: a first auger 14 and a second motor 15. The introduction of the first auger 14 ensures thorough stirring and mixing of the chemical mother liquor during feeding, contributing to the uniform distribution of solid particles within the mother liquor. This allows for a more even distribution of solid particles on the filter screen when the mother liquor enters the filter cartridge 2, reducing the risk of localized clogging and improving separation efficiency. The second motor 15 is fixedly mounted on the feed pipe 3, and its output shaft is fixedly connected to the first auger 14 via a coupling, providing power for the rotation of the first auger 14.

[0027] In a further preferred embodiment of the present invention, a second auger 16 is rotatably installed in the discharge channel 4, and a third motor 17 is fixedly installed on the tank body 1. The output shaft of the third motor 17 is fixedly connected to the second auger 16 through a coupling.

[0028] In this embodiment, the discharge channel 4 has been optimized by introducing two key components: a second auger 16 and a third motor 17. During the solid-liquid separation process, solid particles are trapped and accumulated on the filter cartridge 2 and need to be discharged through the discharge channel 4. However, since solid particles may have different shapes, sizes, and densities, direct discharge may encounter blockages or obstructions. The introduction of the second auger 16, through the driving force generated by its rotation, can effectively and continuously and stably discharge solid particles from the discharge channel 4, avoiding blockages and improving discharge efficiency.

[0029] In a further preferred embodiment of the present invention, a mounting bracket 18 is symmetrically fixedly installed inside the tank 1, and a guide wheel 19 is rotatably installed on the mounting bracket 18. An annular groove is provided on the outer wall of the filter cylinder 2, and the annular groove is adapted to the guide wheel 19.

[0030] In this embodiment, the stability of the mounting frame 18 directly determines the stability of the guide wheel 19 and the filter cartridge 2. Symmetrical installation ensures uniform force distribution on the filter cartridge 2 during rotation, reducing vibration and swaying, thereby improving the overall performance of the equipment. Furthermore, the material and structural design of the mounting frame 18 must meet the corrosion resistance and strength requirements of the chemical mother liquor treatment process. The guide wheel 19 is rotatably mounted on the mounting frame 18, and its shape and position are adapted to the annular groove on the outer wall of the filter cartridge 2. As an auxiliary support and guiding structure for the filter cartridge 2, the guide wheel 19, through its tight fit with the annular groove, effectively reduces friction and wear on the filter cartridge 2 during rotation. Simultaneously, the rolling support of the guide wheel reduces the resistance during filter cartridge rotation, making its rotation smoother and more stable.

[0031] In a further preferred embodiment of this utility model, a valve is provided on the drain pipe 5, and a port is provided at one end of the filter cylinder 2 for discharging solid particles.

[0032] In this embodiment, a valve is provided on the drain pipe 5 to control the opening and closing of the drain pipe. The valve allows the user to flexibly control the timing and amount of discharge of chemical mother liquor according to actual needs. A port is provided at one end of the filter cartridge 2 for discharging solid particles.

[0033] Beneficial effects: The opening allows solid particles to be easily discharged through it, avoiding the clogging and wear problems caused by the long-term accumulation of solid particles in the filter cartridge 2.

[0034] In a further preferred embodiment of the present invention, a support frame is symmetrically fixedly installed at the bottom of the tank body 1, and a base plate is fixedly installed on the bottom end of the support frame.

[0035] In this embodiment, the support frame is symmetrically fixedly installed at the bottom of the tank 1 as the main support structure of the tank. The base plate is fixedly installed on the bottom end of the support frame as a connection and fixing component between the support frame and the ground. The design of the base plate not only increases the contact area between the support frame and the ground, but also improves the overall stability of the equipment.

[0036] In summary, by introducing a rotatable filter cartridge 2, combined with the design of the jet pipe 8 and the air supply mechanism, the accumulation of solid particles in the filter pores is effectively reduced, improving filtration efficiency and permeability. The rotating design of the filter cartridge not only promotes the uniform distribution of the mother liquor but also utilizes airflow to clear the filter pores and prevent clogging. The air supply mechanism, including components such as the fan 9, air outlet pipe 10, filter box 11, and filter plate 12, provides a stable and clean air source for the jet pipe 8. This design ensures that the airflow can effectively clear the filter pores, further enhancing the filter cartridge's anti-clogging capability and ensuring the continuous and efficient operation of the separation process. The introduction of the first auger 14 and the second motor 15 in the feed pipe 3 allows the chemical mother liquor to be fully stirred and mixed during the feeding process, contributing to the uniform distribution of solid particles and thus improving the solid-liquid separation effect. The design of the second auger 16 and the third motor 17 in the discharge channel 4 effectively solves the problem of blockage or obstruction that may be encountered when solid particles are discharged. The rotating driving force of the auger ensures that solid particles can be discharged continuously and stably, improving discharge efficiency.
