Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a centrifugal modular activated carbon tube dynamic adsorption water treatment device. Background Technology

[0002] Activated carbon adsorption is a widely used technology in water treatment, used to remove pollutants such as organic matter, odors, pigments, and some heavy metals from water. Traditional activated carbon adsorption devices (such as fixed beds and filter tanks) mainly rely on the natural flow of water through the activated carbon layer for adsorption, which has the following main problems:

[0003] Adsorption efficiency is limited: the flow velocity of water between activated carbon particles is relatively low and the distribution may be uneven, which means that the adsorption capacity of activated carbon is not fully utilized, and there is room for improvement in adsorption efficiency.

[0004] Easy to clog: Suspended solids in the water can easily deposit on the surface of activated carbon or at the pore inlet, causing blockage, increasing water flow resistance, reducing treatment efficiency, and shortening the service life of activated carbon.

[0005] Inconvenient replacement and maintenance: When activated carbon adsorption is saturated and needs to be replaced, it is usually necessary to shut down the machine, empty the system, disassemble the entire adsorption unit or empty a large amount of bulk activated carbon. The operation is cumbersome, time-consuming and costly.

[0006] Static adsorption is the primary method: In traditional methods, activated carbon is relatively stationary relative to water flow, resulting in limited mass transfer efficiency.

[0007] Therefore, there is an urgent need for a water treatment device that can improve activated carbon adsorption efficiency, reduce clogging, facilitate maintenance, and achieve dynamic enhanced adsorption. Utility Model Content

[0008] The purpose of this invention is to provide a centrifugal modular activated carbon tube dynamic adsorption water treatment device to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal modular activated carbon tube dynamic adsorption water treatment device, comprising a shell, a top cover on the top of the shell, an inlet pipe at the center of the top of the top cover, a shield fixedly installed on the inner wall of the bottom of the shell, a rotating shaft rotatably connected to the center of the top of the shield via a bearing, a bottom support plate fixedly installed on the outer wall of the rotating shaft, an activated carbon filter element installed on the top of the bottom support plate, the outer diameter of the bottom support plate being smaller than the inner diameter of the shell, a driving component inside the shield, the driving end of the driving component being rotatably connected to the rotating shaft, the inlet pipe communicating with the inlet channel of the activated carbon filter element, a cleaning mechanism being provided in the inlet channel of the activated carbon filter element, and an outlet pipe communicating with the side of the shell, the outlet pipe being close to the bottom of the shield.

[0010] Furthermore, the cleaning mechanism includes a chuck, an electric telescopic rod, and a drain outlet. The drain outlet is located at the bottom of the activated carbon filter element. The electric telescopic rod is fixedly installed on the bottom inner wall of the housing. A connecting rod is fixedly connected to the telescopic end of the electric telescopic rod. The chuck is fixedly connected to the top end of the rotating shaft, and the interior of the chuck communicates with the interior of the rotating shaft. The chuck is inserted into the drain outlet. An installation plate is fixedly installed at the top end of the connecting rod. A sealing plug is fixedly sleeved on the outer wall of the top end of the installation plate. The sealing plug is slidably disposed within the chuck. A slot is opened at the top of the installation plate, and an installation shaft is engaged in the slot. The installation shaft extends into the water inlet channel of the activated carbon filter element. A soft brush is fixedly installed on the outer wall of the installation shaft.

[0011] Furthermore, the driving component includes a drive motor, the output end of which is fixedly mounted with a rotating shaft, a gear one is fixedly mounted on the outer wall of the rotating shaft, the gear one meshes with a gear two, and the gear two is fixedly mounted on the outer wall of the rotating shaft.

[0012] Furthermore, a positioning rod is fixedly installed on the top of the base plate, and a positioning hole is opened at the bottom of the activated carbon filter element, into which the positioning rod is inserted.

[0013] Furthermore, a clamping sleeve is rotatably connected to the bottom of the top cover via a bearing, and the clamping sleeve presses against the top of the activated carbon filter element.

[0014] Furthermore, the activated carbon filter element consists of a stainless steel outer shell and activated carbon filled inside the outer shell, and the outer shell has water passage holes.

[0015] Furthermore, a drain port is provided on the bottom inner wall of the housing, the drain port is located inside the shield, and a support frame is provided at the bottom of the drive motor, the support frame being connected to the bottom inner wall of the housing.

[0016] Furthermore, three soft brushes are provided on the mounting shaft, and the soft brushes are distributed in a circumferential array on the mounting shaft.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The centrifugal force generated by the rotating activated carbon filter element, the strong turbulence and high-speed relative motion generated by the centrifugal rotation greatly enhance the mass transfer kinetics of pollutants to the activated carbon surface, break the mass transfer boundary layer limitation of traditional static adsorption, significantly shorten the time required to reach adsorption equilibrium, and improve the processing capacity of the device per unit time.

[0019] 2. It can also effectively prevent clogging and extend service life. The high-speed water flow and centrifugal force form a continuous and strong scouring effect on the surface of activated carbon, which can effectively peel off and prevent the adhesion and accumulation of suspended solids, colloids and biofilms, significantly reduce the risk of clogging, keep the water flow channel unobstructed, thereby extending the service life of activated carbon and reducing the frequency and cost of operation and maintenance.

[0020] 3. It also has the ability of dynamic adsorption, making full use of the adsorption capacity. The modular carbon tube rotates at high speed with the device, and is in a true "dynamic adsorption" state, which helps to make full use of the adsorption sites inside and outside the activated carbon, improve the overall adsorption capacity utilization rate of the activated carbon, and the centrifugal force itself has a certain solid-liquid separation effect, which can remove some larger particles in advance and reduce the load of subsequent activated carbon adsorption.

[0021] 4. A cleaning mechanism that extends into the water inlet channel of the activated carbon filter element is installed to clean up larger particles that have been detached, preventing these larger particles from being pressed against the inner wall of the water inlet channel of the activated carbon filter element under the action of centrifugal force.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Please see Figures 1-7This utility model provides a technical solution: a centrifugal modular activated carbon tube dynamic adsorption water treatment device, including a shell 1, a top cover 2 covering the top of the shell 1, an inlet pipe 201 disposed at the top center of the top of the top cover 2, a shield 6 fixedly installed on the bottom inner wall of the shell 1, a rotating shaft 7 rotatably connected to the top center of the shield 6 via a bearing, a bottom support plate 3 fixedly installed on the outer wall of the rotating shaft 7, an activated carbon filter element 4 installed on the top of the bottom support plate 3, the outer diameter of the bottom support plate 3 being smaller than the inner diameter of the shell 1, and a driving component 8 disposed inside the shield 6. The drive end of component 8 is rotatably connected to the rotating shaft 7. The liquid inlet pipe 201 is connected to the liquid inlet channel of the activated carbon filter element 4. A cleaning mechanism 9 is provided in the water inlet channel of the activated carbon filter element 4. The side of the housing 1 is connected to the liquid outlet pipe 5, which is close to the bottom of the shield 6. The rotating shaft 7 is driven to rotate by the drive component 8. The rotation of the rotating shaft 7 drives the bottom support plate 3 to rotate, which in turn drives the activated carbon filter element 4 to rotate. The centrifugal force generated by the rotating activated carbon filter element 4, the strong turbulence and high-speed relative motion generated by the centrifugal rotation, greatly enhances the transfer of pollutants to the surface of the activated carbon. The mass transfer kinetics process breaks the boundary layer limitation of traditional static adsorption, significantly shortens the time required to reach adsorption equilibrium, improves the processing capacity (flux) of the device per unit time, and can also effectively prevent clogging and extend life. The high-speed water flow and centrifugal force form a continuous and strong scouring effect on the surface of activated carbon, which can effectively peel off and prevent the adhesion and accumulation of suspended solids, colloids and biofilms, significantly reduce the risk of clogging, keep the water flow channel unobstructed, thereby extending the service life of activated carbon, reducing the frequency and cost of operation and maintenance, and has the ability of dynamic adsorption, making full use of adsorption capacity. The modular carbon tube rotates with the device at high speed and is in a true "dynamic adsorption" state, which helps to make full use of the adsorption sites inside and outside the activated carbon, improve the overall adsorption capacity utilization rate of activated carbon, and the centrifugal force itself has a certain solid-liquid separation effect, which can remove some larger particles in advance, reduce the load of subsequent activated carbon adsorption, and a cleaning mechanism 9 is set to extend into the water inlet channel of activated carbon filter element 4 to clean the peeled larger particles, preventing larger particles from being pressed on the inner wall of the water inlet channel of activated carbon filter element 4 under the action of centrifugal force.

[0032] The cleaning mechanism 9 includes a chuck 901, an electric telescopic rod 903, and a drain outlet 9010. The drain outlet 9010 is located at the bottom of the activated carbon filter element 4. The electric telescopic rod 903 is fixedly installed on the bottom inner wall of the housing 1. A connecting rod 902 is fixedly connected to the telescopic end of the electric telescopic rod 903. The chuck 901 is fixedly connected to the top of the rotating shaft 7, and the interior of the chuck 901 communicates with the interior of the rotating shaft 7. The chuck 901 is inserted into the drain outlet 9010. An installation plate 904 is fixedly installed at the top of the connecting rod 902. A sealing plug 905 is fixedly sleeved on the outer wall of the top of the installation plate 904. The sealing plug 905 is slidably disposed within the chuck 901. A slot 906 is provided at the top of the installation plate 904. An installation shaft 908 is engaged in the slot 906. The installation shaft 908 extends into the water inlet channel of the activated carbon filter element 4. A soft brush 909 is fixedly installed on the outer wall of the installation shaft 908. 06. The locking block 907 is used to install the mounting shaft 908. After the activated carbon filter element 4 is installed on the bottom support plate 3, the mounting shaft 908 can be inserted vertically from top to bottom, so that the locking block 907 is locked into the slot 906. The rotating activated carbon filter element 4 comes into contact with the non-rotating soft brush 909, and then the larger particles adsorbed on the inner wall of the water inlet channel of the activated carbon filter element 4 are brushed off. When backwashing the activated carbon filter element 4, the connecting rod 902 can be raised by the electric telescopic rod 903, which in turn raises the mounting plate 904. The rise of the mounting plate 904 raises the sealing plug 905, which leaks the inside of the chuck 901. The backwash water will enter the drain port 9010 from the water inlet channel, then flow into the chuck 901, and then flow out from the rotating shaft 7. This achieves the cleaning of the inner wall of the water inlet channel of the activated carbon filter element 4 without hindering the flow of wastewater during backwashing.

[0033] The driving component 8 includes a drive motor 801. A rotating shaft 802 is fixedly installed at the output end of the drive motor 801. A gear 803 is fixedly installed on the outer wall of the rotating shaft 802. The gear 803 meshes with a gear 804. The gear 804 is fixedly installed on the outer wall of the rotating shaft 7. The drive motor 801 drives the rotating shaft 802 to rotate, which in turn drives the gear 803 to rotate. The rotation of the gear 803 drives the gear 804 to rotate, which in turn drives the rotating shaft 7 to rotate.

[0034] A positioning rod 10 is fixedly installed on the top of the base plate 3, and a positioning hole 11 is opened at the bottom of the activated carbon filter element 4. The positioning rod 10 is inserted into the positioning hole 11. The positioning and connection method of inserting the positioning rod 10 into the positioning hole 11 is adopted so that the positioning rod 10 can push the activated carbon filter element 4 to rotate when the base plate 3 rotates.

[0035] The bottom of the top cover 2 is rotatably connected to a clamping sleeve 12 via a bearing. The clamping sleeve 12 presses against the top of the activated carbon filter element 4. The clamping sleeve 12 is set to press down the activated carbon filter element 4 to prevent the activated carbon filter element 4 from moving up and down. At the same time, because the clamping sleeve 12 rotates, the clamping sleeve 12 can also rotate when the activated carbon filter element 4 rotates, reducing wear on the activated carbon filter element 4.

[0036] The activated carbon filter element 4 consists of a stainless steel outer shell and activated carbon filled inside the outer shell. Water passage holes are provided on the outer shell. The outer shell is used to confine the activated carbon and also serves as a rigid component to connect with other structures.

[0037] The bottom inner wall of the housing 1 is provided with a drain port 13, which is located inside the shield 6. The bottom of the drive motor 801 is provided with a support frame 14, which is connected to the bottom inner wall of the housing 1. The drain port 13 is provided to discharge the sewage flowing out of the rotating shaft 7, while the support frame 14 is used to support the drive motor 801 to prevent the sewage flowing inside the shield 6 from contaminating the drive motor 801.

[0038] There are three soft brushes 909 on the mounting shaft 908. The soft brushes 909 are arranged in a circumferential array on the mounting shaft 908. Multiple soft brushes 909 can improve the cleaning effect.

[0039] Working principle: In use, open the top cover 2 and vertically place the activated carbon filter element 4 onto the bottom support plate 3. When placing it, align the positioning hole 11 at the bottom of the activated carbon filter element 4 with the positioning rod 10 at the top of the bottom support plate 3. Then, vertically insert the mounting shaft 908 from top to bottom, so that the locking block 907 is engaged in the slot 906. Then close the top cover 2 and use bolts to fix the housing 1 and the top cover 2. At this time, the clamping sleeve 12 presses on the top of the activated carbon filter element 4. Turn on the drive motor 801 to drive the rotating shaft 802 to rotate, which in turn drives the gear 803 to rotate. The rotation of gear 803 drives gear 804 to rotate, which in turn drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the base plate 3 to rotate, which in turn drives the activated carbon filter element 4 to rotate. The centrifugal force generated by the rotating activated carbon filter element 4, along with the strong turbulence and high-speed relative motion, greatly enhances the mass transfer kinetics of pollutants to the activated carbon surface. This breaks the mass transfer boundary layer limitation of traditional static adsorption, significantly shortens the time required to reach adsorption equilibrium, increases the processing capacity (flux) of the device per unit time, and effectively prevents clogging, extending its service life. The purified water flows out from the activated carbon filter element 4 and falls onto the shield 6, where it is guided to the outlet pipe 5 and discharged. As the activated carbon filter element 4 rotates, the inner wall of its inlet channel comes into contact with the soft brush 909. The soft brush 909 brushes off the larger particles initially filtered, preventing them from adsorbing onto the inner wall of the inlet channel under centrifugal force. When backwashing is required, the backwash water enters the inlet channel of the activated carbon filter element 4 from outside and flows through... When the activated carbon filter element 4 is in use, the adsorbed particles are flushed out of the activated carbon and into the water inlet channel. At this time, the electric telescopic rod 903 drives the connecting rod 902 to rise, which in turn drives the mounting plate 904 to rise. The rise of the mounting plate 904 drives the sealing plug 905 to rise, which leaks out the inside of the chuck 901. The backwash water then enters the drain port 9010 from the water inlet channel, flows into the chuck 901, and then flows out from the rotating shaft 7. This cleans the inner wall of the water inlet channel of the activated carbon filter element 4 without hindering the outflow of wastewater during backwashing.

[0040] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
