[0002] With the improvement of people's environmental awareness, water pollution and water resource protection have become a very important issue. The treatment of sewage and wastewater has become particularly important. At present, biological fluidized beds are usually used to treat wastewater. Biological fluidized beds use granular materials with a certain specific surface area as carriers and keep the carriers in a flowing state. The biofilm that continuously grows on the surface of the carriers adsorbs, oxidizes and decomposes organic matter in the wastewater, thereby achieving the purpose of removing pollutants in the sewage.

[0003] The prior art application number CN202222294286.1 provides an automatic drainage fluidized bed device, including an anaerobic fluidized bed, an aerobic fluidized bed, an aeration pipe, an exhaust pipe and a water injection pipe, wherein the aerobic fluidized bed is connected to the upper end of the anaerobic fluidized bed, the aeration pipe is installed on the periphery of the aerobic fluidized bed, the exhaust pipe is installed on the periphery of the anaerobic fluidized bed, the water injection pipe is installed on the periphery of the lower end of the anaerobic fluidized bed, the peripheries of the anaerobic fluidized bed and the aerobic fluidized bed are both installed with plug-in pipes, the peripheries of the plug-in pipes are plugged with connecting pipes, a splitting mechanism is connected between the plug-in pipes and the connecting pipes, and a controller is fixedly installed on the upper end of the aerobic fluidized bed. The utility model sets a splitting mechanism so that the anaerobic fluidized bed and the aerobic fluidized bed can be better separated and combined, thereby facilitating later transportation and storage during non-use, and avoiding the problem of poor storage due to the overall height being too high.

[0004] In the above patent, the sliding block is mainly made to pop forward at all times by the elastic force of the spring, and is fixed in the through groove with the snap-fit ​​piece, so as to complete the connection and fixation of the aerobic fluidized bed and the anaerobic fluidized bed and facilitate disassembly. However, in order to meet the liquid flow sealing requirement, this method of fixing the two fluidized beds requires that the diameters of the pipes connected by the plug-in pipe and the connecting pipe be consistent, and since one connecting structure is equipped with four snap-fit ​​pieces, this will result in that during the connection process of the two fluidized beds, two operators need to simultaneously push the snap-fit ​​pieces inward and one operator needs to move the connecting pipe inward to complete the connection of the two fluidized beds, which makes the installation process of the automatic control drainage fluidized bed device too cumbersome and requires more manpower.

[0025] The utility model provides a fluidized bed. A fluidized bed comprises a fluidizing device 1, wherein a fluidizing device 1 is provided with a fluidizing device 11, wherein a fluidizing device 11 is provided with a fluidizing structure 111, wherein a swing key 1112 is provided in the fluidizing structure 111, wherein an electric push rod 1111 is embedded in the swing key 1112, wherein a limit plate 1114 is provided beside the electric push rod 1111, wherein a baffle plate 1113 is provided beside the limit plate 1114, wherein a driven shaft 1115 is engaged with the baffle plate 1113, wherein the ... The outer side of 1115 cooperates with the inner side of the limit plate 1114, the connecting device 1 is connected with a liquid outlet 4, a feeding port 3 is provided next to the liquid outlet 4, a supporting device 2 is installed next to the feeding port 3, the upper end of the supporting device 2 is nested with the lower end of the connecting device 1, a plurality of air holes 13 are embedded in the liquid outlet 4, an anaerobic fluidized bed 14 is clamped on the air hole 13, an aerobic fluidized bed 12 is connected to the anaerobic fluidized bed 14, and a water inlet 15 is installed next to the aerobic fluidized bed 12 The upper end of the water inlet 15 is connected to the lower end of the anaerobic fluidized bed 14, and the tail end of the liquid outlet 4 is nested with the inner side of the aerobic fluidized bed 12. A placement groove 21 is nested on the anaerobic fluidized bed 14, and a plurality of fixed keys 22 are installed next to the placement groove 21. A shell 24 is engaged with the fixed key 22, and a plurality of supporting legs 23 are fixed on the shell 24. The inner side of the fixed key 22 is connected to the outer side of the anaerobic fluidized bed 14, and a mounting groove 112 is sealed on the aerobic fluidized bed 12. A flow port 113 is provided next to the installation groove 112, and a plurality of sealing connection rings 114 are installed next to the flow port 113. A connecting pipe 115 is embedded in the sealing connection ring 114. The outer side of the sealing connection ring 114 is nested with the inner side of the installation groove 112. The upper end of the electric push rod 1111 cooperates with the upper end of the driven shaft 1115. One side of the connector 11 is embedded with the inner side of the aerobic fluidized bed 12, and one side of the connector 11 is engaged with the inner side of the anaerobic fluidized bed 14.

[0026] The model used by the electric linear actuator 1111 is XDHA24-500. With its advantages such as silent gears, stable base, low-resistance metal casing, etc., the electric linear actuator 1111 can operate more stably and for a long time in the fluidized bed.

[0027] The sealing connection ring 114 is made of elastic rubber material, and its diameter is smaller than the diameter of the installation groove 112 , so that the sealing connection ring 114 can be more tightly inserted into the installation groove 112 and keep the seal at all times.

[0028] The size of the inner hole of the limiting plate 1114 is consistent with the diameter of the driven shaft 1115 , so that the limiting plate 1114 can directly limit the movement of the driven shaft 1115 .

[0029] The working principle of the present invention is described as follows: the various mechanical structures inside the fluidized bed are all fixed by threads unless otherwise specified. In order to more intuitively observe the professional and technical features in the figure, the bolted connections are appropriately hidden. Before the fluidized bed is used, the anaerobic fluidized bed 14 and the aerobic fluidized bed 12 need to be placed vertically. There are corresponding sewage treatment devices inside the fluidized bed. Since the anaerobic fluidized bed 14 and the aerobic fluidized bed 12 are mature existing technologies for purifying sewage, the present invention does not elaborate on them. When the fluidized bed is running, the anaerobic fluidized bed 14 at the bottom is stably fixed at the bottom by the placement groove 21 and the fixing key 22. The user adds the sewage to be purified into the anaerobic fluidized bed 14 along the water inlet 15. After entering, the sewage will directly enter the aerobic fluidized bed 12 through the connecting pipe 115. Finally, the purified sewage is discharged through the liquid outlet 4. When installing the fluidized bed, the user only needs to take the connecting pipe 115 and insert it into the two installation grooves 112. Since the connecting pipe 115 is equipped with a sealing connecting ring 114, the entire connector 11 can be in an internally sealed state, and only one operator is required to complete it, and it is very convenient to disassemble and assemble. When the user needs to control the water flow in and out of the anaerobic fluidized bed 14 and the aerobic fluidized bed 12, it is only necessary to control the electric push rod 1111. The contraction of the electric push rod 1111 can directly move the driven shaft 1115 downward. The limit plate 1114 is used to limit the driven shaft 1115 to move downward only. Then the baffle plate 1113 controls the opening size of the flow port 113 to complete the control of the flow rate.

[0030] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the utility model is limited by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model.
