Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment devices, and particularly to a wastewater treatment device based on an enzyme biocatalyst. Background Art

[0002] At present, the method of using an enzyme biocatalyst to treat wastewater has been widely applied. Its working principle is to utilize the series of bio-enzyme binding technologies of different types of ordinary microbial bacteria. The enzyme can break the chemical bonds in various pollutants and degrade large-molecule organic substances into small-molecule organic substances or inorganic substances such as water and carbon dioxide, achieving a good pollutant removal effect.

[0003] The existing Chinese patent with the publication number CN208814793U discloses a catalyst wastewater treatment device, including a water inlet pipe and a connection platform. A valve is installed on the front surface of the water inlet pipe. The upper part of the connection platform is welded and fixed to the bottom of the first treatment box body. A surface chute is opened on the front surface of the fixed platform. One side of the first treatment box body is connected to one side of the fixed frame body. A stirring shaft is arranged through the inside of the second treatment box body, and stirring blades are symmetrically fixed on both sides of the stirring shaft. Connection frame bodies are symmetrically fixed on both sides of the fixed frame body.

[0004] In view of the above related technologies, it is found that most of the existing wastewater treatment devices can only use a stirring mechanism installed in the treatment tank for stirring operations after adding the catalyst. Not only is the mixing effect limited, but also stratification is likely to occur, resulting in uneven treatment effects between the upper and lower parts. Summary of the Invention

[0005] In order to achieve the effect of stable feeding of the enzyme biocatalyst and uniform mixing with the wastewater, the present application provides a wastewater treatment device based on an enzyme biocatalyst.

[0006] The present invention is implemented as follows:

[0007] A wastewater treatment device based on an enzyme biocatalyst includes a base. The upper end surface of the base is provided with a first treatment barrel and a second treatment barrel. The first treatment barrel and the second treatment barrel are both fixedly connected to the base, and a mixing component is installed between the first treatment barrel and the second treatment barrel. Both sides of the mixing component extend into the first treatment barrel and the second treatment barrel respectively, for mixing the wastewater in the first treatment barrel and the second treatment barrel with each other. The upper end surfaces of the first treatment barrel and the second treatment barrel are fixedly installed with a wastewater tank. A feeding component is fixedly installed at the front end of the wastewater tank, and a diversion grid plate is installed in the wastewater tank.

[0008] By adopting the above technical solution, the base is provided to facilitate the stable installation and use of the first treatment barrel and the second treatment barrel. In this way, during processing, the wastewater can be mixed and reacted with the enzyme biocatalyst in the first treatment barrel and the second treatment barrel respectively. At the same time, by installing a mixing component between the first treatment barrel and the second treatment barrel, it is easy to exchange the wastewater between the two treatment barrels through the mixing component during the wastewater treatment process, and the wastewater at different upper and lower layers in the treatment barrel can also be exchanged with each other. In this way, more uniform mixing can be achieved, and different mixing methods can be adopted according to the treatment needs, making it very flexible to use. By fixedly installing a wastewater tank on the upper end faces of the first treatment barrel and the second treatment barrel, it is easy to add the wastewater to be processed into the wastewater tank during use, and then the wastewater is filtered and shunted through the shunt mesh plate in the wastewater tank and discharged into the first treatment barrel and the second treatment barrel for treatment operations. By setting the feeding component, the catalyst can be added to the first treatment barrel and the second treatment barrel for use, ensuring that the catalyst can be mixed with the wastewater in the treatment barrel for treatment.

[0009] Furthermore, the base includes a seat plate and a seat cover. The seat cover is arranged on the upper end face of the seat plate. Symmetrically arranged on the upper end of the seat plate are installation vertical plates for positioning and installing the seat cover. A number of threaded holes are evenly formed in the installation vertical plates. Corresponding mating holes are formed on both sides of the seat cover, and a control panel is fixedly installed on the front end face of the seat cover.

[0010] By adopting the above technical solution, through the structural setting of the base, it is ensured that the first treatment barrel and the second treatment barrel can be conveniently supported and fixed by the seat plate, ensuring the stability during the processing of the first treatment barrel and the second treatment barrel. At the same time, by setting the seat cover, the purpose of shielding and protecting the mixing component is achieved, and setting the mixing component in the seat cover can ensure that the noise impact of the mixing component on the outside is reduced during the processing. Through the setting of the installation vertical plates, it is easy for the seat cover to be quickly positioned and installed, and through the setting of the threaded holes and the mating holes, it is convenient to fix the two with bolts after the seat cover is installed on the vertical plates, ensuring the stable protection and noise reduction use of the seat cover. By fixedly installing a control panel on the front end of the seat cover, it is easy to control the equipment to process wastewater through the control panel during use.

[0011] Furthermore, both the first treatment barrel and the second treatment barrel include an outer barrel shell, an inner barrel liner, and a bottom plate seat. The inner barrel liner is fixedly installed in the outer barrel shell, and an annular groove is provided between the inner barrel liner and the outer barrel shell. The bottom plate seat is fixedly installed on the lower end face of the outer barrel shell, and a temperature control pipe group is arranged on the upper end face of the bottom plate seat. The temperature control pipe group is installed in the annular groove and is in contact with the outer side surface of the inner barrel liner.

[0012] By adopting the above technical solution, the structures of the first treatment barrel and the second treatment barrel are used to ensure that an outer barrel shell can be arranged outside the inner barrel liner during use, so as to protect the inner barrel liner through the outer barrel shell. At the same time, an annular groove for installing the temperature control pipe group is arranged between the inner barrel liner and the outer barrel shell. After the bottom plate seat is fixedly installed on the lower end surface of the outer barrel shell, the temperature control pipe group can be stably sleeved on the outer side surface of the inner barrel liner. In this way, during the process of treating wastewater, the temperature control pipe group can be used to control the temperature during the treatment process, so that the wastewater and the catalyst can be treated at an appropriate temperature. Here, the temperature control pipe group can be realized by the structure of an electric heating pipe and a temperature control board in cooperation.

[0013] Further, the mixing component includes a flow pump, an adsorption pipe group and a discharge pipe group. A three-way valve is installed at the liquid outlet of the flow pump. The adsorption pipe group is connected to the liquid inlet of the flow pump. The discharge pipe group is installed on one outlet of the three-way valve. A drain pipe is installed on the other outlet of the three-way valve. Shunt pipe groups are installed on both the adsorption pipe group and the discharge pipe group, and the shunt pipe groups are hermetically and fixedly connected to both the adsorption pipe group and the discharge pipe group. The two ends of the shunt pipe group are respectively inserted into the first treatment barrel and the second treatment barrel, and the two ends of the shunt pipe group are hermetically connected to the inner barrel liner of the first treatment barrel and the inner barrel liner of the second treatment barrel respectively.

[0014] By adopting the above technical solution, the structure of the mixing component is set to ensure that a three-way valve can be installed at the liquid outlet of the flow pump during use, and the adsorption pipe group is directly connected to the liquid inlet of the flow pump. During use, the liquid can be sucked into the flow pump through the adsorption pipe group, and the three-way valve is set to facilitate controlling the adsorbed liquid to be discharged from the discharge pipe group or the drain pipe during use. At the same time, by installing shunt pipe groups on the adsorption pipe group and the discharge pipe group, it is convenient to cooperate and connect with the first treatment barrel and the second treatment barrel through the shunt pipe groups. During use, the adsorption pipe group can suck the waste liquid at the lower end in the first treatment barrel or the second treatment barrel into the flow pump through the shunt pipe group, and the discharge pipe group can discharge the waste liquid back to the upper end in the first treatment barrel or the second treatment barrel through the shunt pipe group.

[0015] Further, a suspension seat is fixedly installed on the upper end surface of the flow pump. A concave positioning frame is arranged on the suspension seat. Connecting holes are symmetrically opened on both sides of the concave positioning frame, and the concave positioning frame is fixed to the first treatment barrel and the second treatment barrel by bolts. A threaded rod connected to the suspension seat is welded and fixed on the concave positioning frame, and a locking nut is installed on the threaded rod.

[0016] By adopting the above technical solution, a suspension seat is fixedly installed on the upper end face of the flow pump. When in use, the flow pump can be fixedly installed on the concave positioning frame through the suspension seat, and the concave positioning frame is fixedly installed on the treatment barrel. In this way, the flow pump and the treatment barrel can be fixed to each other, ensuring the stability during use. At the same time, through the settings of the threaded rod and the locking nut, it is convenient for the suspension seat and the concave positioning frame to be stably connected and easy to disassemble during later maintenance.

[0017] Furthermore, the shunt pipe group includes a central pipe, a plurality of left pipes and a plurality of right pipes. The left pipes and the right pipes are arranged on both sides of the central pipe, and both the left pipes and the right pipes are communicated with the central pipe. Control valves are installed on both the left pipes and the right pipes.

[0018] By adopting the above technical solution, through the structural setting of the shunt pipe group, it is ensured that the left pipes and the right pipes are fixedly installed on the central pipe. When in use, it is convenient for the left pipes to extend into the first treatment barrel for use, and the right pipes to extend into the second treatment barrel for use. Moreover, both the left pipes and the right pipes are provided with several with different heights. In this way, liquid suction or drainage can be carried out at different depths of the treatment barrel. At the same time, by installing control valves on the left pipes and the right pipes, it is easy to flexibly select to open according to actual needs during use to meet different usage requirements.

[0019] Furthermore, the wastewater tank includes a tank seat, a main housing, and two shunt housings corresponding to the first treatment barrel and the second treatment barrel. The tank seat is fixedly installed on the front end face of the main housing for the dosing assembly to be fixedly installed, and a fixing seat for limiting the dosing assembly is also provided on the front end face of the tank seat. The shunt housing is fixedly installed on the lower end face of the main housing, and the shunt housing is communicated with the main housing.

[0020] By adopting the above technical solution, through the structural setting of the wastewater tank, it is ensured that the main housing receives the wastewater to be treated. At the same time, by fixedly installing the tank seat on the front end of the main housing, it is convenient to install the dosing assembly through the tank seat, and it is easy for the dosing assembly to stably dose the catalyst for use. At the same time, by fixedly installing two shunt housings on the lower end of the main housing, it is ensured that the wastewater in the main housing can stably flow into the treatment barrel through the shunt housings, allowing the wastewater and the catalyst to react in the treatment barrel.

[0021] Furthermore, the dosing component includes a container housing, a flow splitting pipe head, a plunger block and a driving component. The container housing is fixedly installed in the fixed seat. The flow splitting pipe head is installed on the lower end face of the container housing and is fixedly and sealingly connected to the container housing. Drainage elbows connected to the inner barrel are installed at both ends of the flow splitting pipe head. One-way valves are installed in the drainage elbows. The plunger block is installed in the container housing and is sealingly and slidably connected to the container housing. The driving component is fixedly installed on the container housing and is used to drive the plunger block to move in the container housing.

[0022] By adopting the above technical solution, the structure of the dosing component is arranged to ensure that the catalyst is stored in the container housing. Moreover, by installing the plunger block in the container housing, it is easy for the plunger block to press down the catalyst under the drive of the driving component during use, ensuring that the catalyst can be stably discharged from the lower flow splitting pipe head. At the same time, by installing drainage elbows at both ends of the flow splitting pipe head, it can be ensured that the catalyst is sent into the inner barrel through the drainage elbows, so that the catalyst is mixed with the wastewater in the inner barrel. At the same time, by installing one-way valves in the drainage elbows, the situation of backflow in the drainage elbows during the process of adding the catalyst can be effectively avoided.

[0023] Furthermore, the plunger block includes a threaded pipe sleeve and a rubber block. The threaded pipe sleeve is fixedly installed at the center of the rubber block. The driving component includes a stepping motor and a threaded vertical rod that cooperates with the threaded pipe sleeve. A suspension for installing the stepping motor is fixedly provided on the upper end face of the container housing. The output end of the stepping motor is installed downward on the suspension, and the threaded vertical rod is fixedly connected to the output end of the stepping motor.

[0024] By adopting the above technical solution, the structure of the plunger block is arranged to ensure that the rubber block can be connected to the threaded vertical rod on the driving component through the centrally installed threaded pipe sleeve during use, ensuring that when the plunger block needs to be moved, the stepping motor can drive the threaded rod to rotate, and then the purpose of driving the plunger block to move in the container housing is achieved through the cooperation of the threaded rod and the threaded pipe sleeve. By fixedly installing the suspension on the upper end face of the container housing, it is convenient to stably install the stepping motor through the suspension, ensuring that the stepping motor can be stably used on the upper end of the container housing. Moreover, by suspending the stepping motor, the plunger block can be slid out of the container housing when the catalyst needs to be added.

[0025] Furthermore, the flow splitting mesh plate includes a bent grid frame, a filter mesh plate and a hanging plate frame. The filter mesh plates are symmetrically installed in the bent grid frame and are fixedly connected to the bent grid frame. The hanging plate frames are fixedly installed at both ends of the bent grid frame. A support plate for supporting the bent grid frame is also fixedly installed in the middle of the main housing.

[0026] By adopting the above technical solution, the structure of the shunt grid plate is set to ensure that the filter grid plate is installed by bending the grid frame. During the process of adding wastewater, the wastewater can be filtered through the installation filter grid plates inclined on both sides, ensuring that impurities can remain on the filter grid plate and facilitating better cleaning operations. At the same time, by installing hanging plate frames on both sides of the bending grid frame, it is ensured that the shunt grid plate is more stable when installed in the main housing. At the same time, by fixedly installing a support plate in the middle of the main housing, the middle of the bending grid frame is supported by the support plate, further increasing the service strength of the shunt grid plate and avoiding deformation during the process of adding wastewater.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] (1) In this application, by arranging two treatment barrels on the base, it is convenient to carry out mixing reactions with catalysts in the two treatment barrels respectively when treating wastewater. During the mixing reaction process, the wastewater can be exchanged and mixed between the two treatment barrels through the mixing component, and the upper and lower layer wastewater can also be repeatedly mixed through the mixing component, thereby achieving more uniform mixing and improving the mixing efficiency of the wastewater and the catalyst. After the wastewater treatment is completed, it can be stably discharged through the drain pipe, so as to achieve the purpose of improving the wastewater treatment efficiency.

[0029] (2) In this application, the treatment barrel is designed as a structure in which the outer barrel shell and the inner barrel liner cooperate, and a temperature control pipe group is installed between the outer barrel shell and the inner barrel liner. Baoheng can stably control the treatment temperature of the wastewater during the wastewater treatment process, so as to ensure that the wastewater can be treated at an appropriate temperature at any time, thereby ensuring better wastewater treatment effect.

[0030] (3) In this application, a feeding component is fixedly installed on the box seat. Before use, the catalyst for treating wastewater can be placed in the container shell, and then the plunger block is driven by the driving component to extrude the catalyst. During use, the feeding amount of the catalyst can be controlled by controlling the moving distance of the plunger block, so as to achieve the purpose of automatic feeding of the catalyst.

The driving assembly 64 is fixedly installed on the container shell 61, and the driving assembly 64 is used to drive the plunger block 63 to move in the container shell 61. By setting the structure of the feeding assembly 6, it is ensured that the catalyst is stored through the container shell 61. Moreover, by installing the plunger block 63 in the container shell 61, it is easy for the plunger block 63 to achieve the purpose of pressing down the catalyst driven by the driving assembly 64 during use, ensuring that the catalyst can be stably discharged from the lower shunt pipe head 62. At the same time, by installing the drainage elbow pipes 621 at both ends of the shunt pipe head 62, it can be ensured that the catalyst is sent into the inner barrel 22 through the drainage elbow pipes 621, so that the catalyst is mixed with the wastewater in the inner barrel 22. At the same time, by installing check valves in the drainage elbow pipes 621, the situation of backflow in the drainage elbow pipes 621 during the process of adding the catalyst can be effectively avoided.

In this way, when it is necessary to add a catalyst, the plunger block 63 can be slid out of the container shell 61.

[0060] For the device provided by the embodiment of the present invention, its implementation principle and the technical effects produced are the same as those of Embodiment 1. For a brief description, for the parts not mentioned in this embodiment, reference can be made to the corresponding content in Embodiment 1.

[0061] Working principle: When it is necessary to process and treat wastewater, the wastewater is directly discharged into the main housing 52. After entering the main housing 52, the wastewater can be shunted and filtered by the shunt mesh plate 7. The filtered wastewater can stably flow into the lower first treatment barrel 2 and second treatment barrel 3 through the shunt housing 53. Then, the driving assembly 64 drives the plunger block 63 to move downward in the container shell 61, so as to squeeze the catalyst in the container shell 61 into the lower shunt pipe head 62, and it is discharged into the treatment barrel through the drainage elbows 621 on both sides of the shunt pipe head 62, so that the catalyst and the wastewater can be mixed together. In order to increase the mixing uniformity, the flow pump 41 can be started to exchange the mixed liquid in the first treatment barrel 2 and the second treatment barrel 3, and at the same time, the liquid in the treatment barrel can be continuously mixed up and down. After the wastewater is treated, the three-way valve 410 can be used to open the drain pipe 46 to discharge the treated wastewater from the drain pipe 46.

[0062] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
