Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for the production of brown algae polysaccharides. Background Technology

[0002] This device is specifically designed to treat wastewater generated during the production of brown algae polysaccharides. Brown algae polysaccharides are an important class of bioactive substances extracted from brown algae. During the production process, various chemical reagents are used, and the raw materials themselves also release some substances, resulting in wastewater with complex composition.

[0003] The mixed wastewater enters the solid-liquid separator, where solid impurities such as kelp residue are removed mechanically. The separated liquid flows into the mixed wastewater preconditioning tank, where formaldehyde and other harmful substances are further removed through aeration oxidation. The pretreated wastewater then enters the biological conditioning filter, where microorganisms degrade organic pollutants and harmful substances such as ammonia nitrogen. The biologically treated wastewater then passes through the flotation tank, where flocculants are added to coagulate suspended solids into larger particles. The scum is then separated by a scum scraper to further reduce the concentration of suspended solids in the water. The flotation-treated wastewater then enters the flocculation reaction tank, where flocculants are added to coagulate and settle colloidal particles. The supernatant after sedimentation enters the circulating oxidation reactor, while the sludge is transported off-site for disposal through the sludge discharge system. The mixed wastewater and waste calcium water are mixed in the circulating oxidation reactor and further treated using oxidants such as ozone.

[0004] Traditional physical sedimentation and filtration methods are difficult to effectively remove organic matter and salt from wastewater, resulting in the treated water quality failing to meet discharge standards. Biological treatment processes have high requirements for water quality and environmental conditions, unstable treatment efficiency, and are prone to generating secondary pollution such as sludge, and the equipment is difficult to clean. Utility Model Content This solves the problems of poor filtration and difficulty in cleaning existing devices, avoids secondary pollution, and improves processing efficiency. In view of the above-mentioned problems with filtration and cleaning, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wastewater treatment device for the production of brown algae polysaccharides, comprising a body, a processing chamber formed on the inner wall of the body, a cylinder fixedly connected to the inner wall of the processing chamber, a large-pore filter screen fixedly installed on the inner wall of the cylinder, a small-pore filter plate fixedly connected to the inner wall of the cylinder on the outer wall of the large-pore filter screen, a plurality of evenly distributed circular tubes slidably connected to the inner wall of the large-pore filter screen, a plurality of evenly distributed jet nozzles corresponding to the circular tubes slidably connected to the outer wall of the small-pore filter plate, and a water outlet pipe communicating with the processing chamber formed on the outer wall of the body, with an activated carbon filter layer clamped to the inner wall of the water outlet pipe.

[0006] As a preferred embodiment of the wastewater treatment device for the production of brown algae polysaccharides according to this utility model, the bottom end of the machine body is provided with a water inlet pipe communicating with the processing chamber, the top end of the machine body is fixedly installed with a reduction motor, the output end of the reduction motor is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to an exhaust pipe communicating with the inner wall of the round pipe, and the inner wall of the machine body is fixedly connected to a pressure gauge.

[0007] As a preferred embodiment of the wastewater treatment device for the production of brown algae polysaccharides according to this utility model, the outer wall of the exhaust pipe has two support rods that are mirror-distributed and communicate with the inner wall of the jet head, the inner wall of the exhaust pipe has two diverter plates that are mirror-distributed and fixedly connected to the bottom end of the support rods, and the top end of the exhaust pipe has an air inlet pipe.

[0008] As a preferred embodiment of the wastewater treatment device for the production of brown algae polysaccharides according to this utility model, the outer wall of the air inlet pipe is fixedly connected to a cavity compressor that is fixedly connected to the top of the machine body, the bottom end of the support rod is fixedly connected to a connecting plate that is slidably connected to the inner wall of the cylinder, and the bottom end of the exhaust pipe is provided with a sewage pipe that communicates with the processing chamber.

[0009] As a preferred embodiment of the wastewater treatment device for the production of brown algae polysaccharides according to this utility model, the outer wall of the activated carbon filter layer is fixedly connected to an installation block that is slidably connected to the inner wall of the outlet pipe. Both sides of the outer wall of the installation block are fixedly connected to sealing gaskets that are slidably connected to the inner wall of the outlet pipe. The inner wall of the outlet pipe is slidably connected to two mirror-distributed locking blocks that are slidably connected to the inner wall of the installation block.

[0010] As a preferred embodiment of the wastewater treatment device for the production of brown algae polysaccharides according to this utility model, a first spring is connected between the outer wall of the locking block and the inner wall of the outlet pipe, a trapezoidal block is slidably connected to the inner wall of the mounting block, a push rod is slidably connected to the top of the trapezoidal block and slidably connected to the inner wall of the mounting block, and two evenly distributed second springs are connected between the inner wall of the push rod and the inner wall of the mounting block.

[0011] The beneficial effects of this utility model are: 1. Wastewater passes through a large-pore filter screen, a small-pore filter plate, and an activated carbon filter layer, achieving comprehensive purification from intercepting large particulate impurities to adsorbing fine pollutants. The large-pore filter screen first intercepts larger solid impurities, the small-pore filter plate further filters fine particles, and finally the activated carbon filter layer deeply adsorbs organic pollutants, pigments, and odors. This layer-by-layer filtration ensures that the wastewater treatment meets standards. At the same time, when the filter screen and filter plate experience increased water flow resistance and decreased pressure due to impurity accumulation, the geared motor drives the exhaust pipe to rotate, and the jet nozzle sprays towards the filter components. The strong airflow blows the impurities clogging the filter structure into the round pipe and discharges them through the drain pipe, avoiding reduced filtration efficiency due to blockage, ensuring continuous and stable operation of the device, and reducing the frequency of manual cleaning and maintenance costs.

[0012] 2. By squeezing the push rod, the locking block retracts and detaches from the installation block under the linkage of the spring and the trapezoidal block, allowing the old activated carbon filter layer to be easily extracted. When installing the new filter layer, align it and insert it into the outlet pipe. The locking block automatically engages under the spring force, quickly completing the fixation. The sealing gasket ensures a tight and leak-free connection, guaranteeing the filtration effect. This design simplifies the replacement process of the activated carbon filter layer, shortens maintenance time, and allows operators to replace the filter layer regularly and conveniently, maintaining the device's deep purification capability for wastewater and ensuring that the wastewater treatment quality always meets the standard requirements.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1:

[0019] Reference Figure 1-3This is the first embodiment of the present invention, which provides a wastewater treatment device for the production of brown algae polysaccharides. The device includes a body 1, a processing chamber on the inner wall of the body 1, a cylinder 6 fixedly connected to the inner wall of the processing chamber, a large-pore filter screen 15 fixedly installed on the inner wall of the cylinder 6, a small-pore filter plate 16 fixedly connected to the inner wall of the cylinder 6 on the outer wall of the large-pore filter screen 15, a plurality of evenly distributed circular tubes 14 slidably connected to the inner wall of the large-pore filter screen 15, and a plurality of evenly distributed jet nozzles 13 corresponding to the circular tubes 14 slidably connected to the outer wall of the small-pore filter plate 16. The jet nozzles 13 rotate synchronously with the circular tubes 14. A water outlet pipe 4 communicating with the processing chamber is opened on the outer wall of the body 1, and an activated carbon filter layer 10 is snapped into the inner wall of the water outlet pipe 4. The activated carbon filter layer 10 is used to further purify the wastewater.

[0020] The bottom of the machine body 1 is provided with a water inlet pipe 2 that communicates with the processing chamber. A geared motor is fixedly installed at the top of the machine body 1. A rotating shaft 8 is fixedly connected to the output end of the geared motor. An exhaust pipe 9 that communicates with the inner wall of the circular tube 14 is fixedly connected to the outer wall of the rotating shaft 8. The exhaust pipe 9 is used to drive impurities through the sewage pipe 3. A pressure gauge 5 is fixedly connected to the inner wall of the machine body 1. The pressure gauge 5 is used to monitor the blockage of the inner wall of the cylinder 6.

[0021] The outer wall of the exhaust pipe 9 has two support rods 12 that are mirror-distributed and communicate with the inner wall of the jet head 13. The inner wall of the exhaust pipe 9 is fixedly connected to two diverter plates 11 that are mirror-distributed and fixedly connected to the bottom end of the support rods 12. The diverter plates 11 are used to divide the airflow into three parts. The top end of the exhaust pipe 9 has an intake pipe 7.

[0022] During use, wastewater enters the processing chamber of the machine body 1 through the inlet pipe 2. The wastewater first flows into the cylinder 6 and passes through the large-pore filter screen 15 and the small-pore filter plate 16 in sequence. The large-pore filter screen 15 intercepts larger particles of impurities, and the small-pore filter plate 16 further filters smaller particles, achieving preliminary purification of the wastewater. The preliminarily purified wastewater continues to flow and passes through the outlet pipe 4, where it undergoes deep adsorption filtration through the activated carbon filter layer 10 to remove residual organic pollutants, pigments, and odors from the water, ultimately meeting the discharge standards before being discharged. During the filtration process, impurities gradually accumulate on the large-pore filter screen 15 and the small-pore filter plate 16. When too many impurities accumulate and block the pores of the filter screen and filter plate, the water flow resistance increases and the pressure inside the processing chamber decreases. At this time, the pressure gauge 5 installed on the inner wall of the machine body 1 detects the decrease in pressure and sends a signal to the PLC controller. The PLC controller starts the geared motor, and the output end of the geared motor drives the rotating shaft 8 to rotate. The exhaust pipe 9 connected to the rotating shaft 8 rotates accordingly. At the same time, the cavity compressor starts, and the output compressed air enters the exhaust pipe 9 from the air inlet pipe 7. After being divided by the flow divider plate 11, it enters the jet head 13 through the support rod 12. The jet head 13 sprays high-speed airflow toward the large-pore filter screen 15 and the small-pore filter plate 16, blowing away the impurities and causing them to enter the exhaust pipe 9 through the round pipe 14. Then, driven by the airflow, they are discharged from the drain pipe 3, realizing the automatic cleaning of the filter screen and filter plate and ensuring the continuous and efficient operation of the device. Example 2:

[0023] Reference Figure 1 , Figure 2 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the outer wall of the air inlet pipe 7 is fixedly connected to a cavity compressor that is fixedly connected to the top of the body 1. The air compressor is used to increase the gas pressure and deliver it to the exhaust pipe 9. The bottom end of the support rod 12 is fixedly connected to a connecting plate 17 that is slidably connected to the inner wall of the cylinder 6. The bottom end of the exhaust pipe 9 is provided with a drain pipe 3 that communicates with the processing chamber.

[0024] An installation block 19 is fixedly connected to the outer wall of the activated carbon filter layer 10 and slidably connected to the inner wall of the water outlet pipe 4. Both sides of the outer wall of the installation block 19 are fixedly connected to sealing gaskets 18 that are slidably connected to the inner wall of the water outlet pipe 4. The sealing gaskets 18 are used to prevent water from seeping out. Two mirror-distributed locking blocks 20 are slidably connected to the inner wall of the water outlet pipe 4 and are slidably connected to the inner wall of the installation block 19. The locking blocks 20 are used to lock the installation block 19.

[0025] A first spring 21 is connected between the outer wall of the locking block 20 and the inner wall of the water outlet pipe 4. The first spring 21 is used to push the locking block 20. A trapezoidal block 22 is slidably connected to the inner wall of the mounting block 19. The trapezoidal block 22 is limited to the inner wall of the mounting block 19. A push rod 23 is slidably connected to the top of the trapezoidal block 22 and is slidably connected to the inner wall of the mounting block 19. The bottom end of the push rod 23 is chamfered. Two evenly distributed second springs 24 are connected between the inner wall of the push rod 23 and the inner wall of the mounting block 19. The second springs 24 are used to push the push rod 23.

[0026] During use, to ensure the wastewater treatment effect, the activated carbon filter layer 10 needs to be replaced regularly. The operator squeezes the push rod 23 on the inner wall of the mounting block 19. The push rod 23 slides downward against the elastic force of the second spring 24, which drives the two trapezoidal blocks 22 to move left and right to squeeze the locking block 20. This causes the locking block 20 to retract against the elastic force of the first spring 21 and into the inner wall of the outlet pipe 4, releasing the locking and fixing of the mounting block 19. At this time, the operator can easily pull the mounting block 19 together with the activated carbon filter layer 10 out of the outlet pipe 4. After removing the old activated carbon filter layer 10 and replacing it with a new one, align the mounting block 19 with the water outlet pipe 4 and insert it. As the mounting block 19 is inserted, the locking block 20 automatically pops out under the elastic force of the first spring 21 and locks into the inner wall of the mounting block 19, thus quickly fixing the new activated carbon filter layer 10. The sealing gaskets 18 on both sides of the outer wall of the mounting block 19 ensure the sealing of the connection, prevent wastewater leakage, and ensure that the activated carbon filter layer 10 functions properly. The operation is now complete.

[0027] The remaining structure is the same as that in Example 1.

[0028] 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. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
