[0002] The bio-rotor is a biofilm wastewater treatment technology developed on the basis of the biofilter, also known as the immersed biofilter. The bio-rotor is a biological treatment structure consisting of a water tank and a rotating disk partly immersed in the sewage. It mainly includes a rotating disc (disc), a contact reaction tank, a rotating shaft and a driving device. If necessary, a protective cover can be set above the oxidation tank to protect against wind and rain and to keep warm. The process has the advantages of flexible system design, convenient installation, simple operation, reliable system, low operation and running costs; its mechanism of purifying organic matter is basically the same as that of the biofilter, but its structural form is different from that of the biofilter.

[0003] For example, the utility model disclosed in the publication (announcement) number: CN213771478U discloses a biological turntable, including at least one group of discs, any group of discs includes an electric heating film, a temperature detection element and a controller, the electric heating film can be powered on to generate heat, and the temperature detection element is used to detect the surface temperature of the disc. When the temperature detection element detects that the surface temperature of the disc is lower than the preset temperature, the temperature detection element feeds back a signal to the controller, and the controller controls the electric heating film to heat up until the surface temperature of the disc is equal to the preset temperature, thereby automatically adjusting the surface temperature of the disc, so that the disc continues to operate at the preset temperature, avoiding the microorganisms on the disc from reducing their activity due to low temperature, so that the purification effect of the disc is not affected by the ambient temperature, and the purification effect and adaptability are improved.

[0021] Example

[0022] See also Figure 1-4 The figure shows a preferred embodiment of the utility model, a biological turntable for sewage treatment that is easy to disassemble and assemble, including a rotating shaft 1, two mounting blocks 2 are respectively clamped on both sides of the rotating shaft 1, and a plurality of connecting blocks 3 are fixedly connected to the mounting blocks 2, the connecting blocks 3 have chambers, and discs 4 are clamped in the chambers of the connecting blocks 3, and each disc 4 has a limiting rod 6 clamped on one side.

[0023] A plurality of connection blocks 3 are linearly distributed along one end of the installation block 2 .

[0024] It is understandable that: by linearly arranging a plurality of connecting blocks 3 on the mounting block 2, a plurality of groups of disks 4 can be pre-assembled on the connecting blocks 3 of the mounting block 2, and then each mounting block 2 can be directly snapped onto the rotating shaft 1 for convenient installation.

[0025] Both ends of each mounting block 2 are fixedly connected with an arc-shaped clamping plate 7 , and a clamping groove cooperating with the arc-shaped clamping plate 7 is formed on the rotating shaft 1 .

[0026] It can be understood that: in order to facilitate the staff in the installation process of the device, arc-shaped clamping plates 7 are fixedly connected at both ends of the mounting block 2, and a clamping groove that cooperates with the arc-shaped clamping plates 7 is opened on the rotating shaft 1. The staff can install the mounting block 2 with the disk 4 installed on the rotating shaft 1 as a whole through the arc-shaped clamping plates 7 at both ends.

[0027] An oblique insert block is arranged at one end of the limiting rod 6, and a slot which cooperates with each other is opened at a corresponding position at the bottom end of each disk 4.

[0028] It can be understood that in order to increase the stability of the connection between the disk 4 and the connecting block 3 and avoid shaking, an oblique insertion block is provided on the limit rod 6, and mutually matching slots are opened at the corresponding position of the disk 4, so that the disk 4 can be inserted into the connecting block 3 through the mutual cooperation between the oblique insertion block and the slot for clamping.

[0029] A circular through groove is formed on one side of the connecting block 3 , and an annular clamping block 5 is slidably connected in the circular through groove. The annular clamping block 5 is sleeved and fixed on the limiting rod 6 .

[0030] It can be understood that: in order to ensure that the limiting rod 6 on one side will not jam the disk 4 during the process of inserting the disk 4 into the connecting block 3, a circular through groove is opened on one side of the connecting block 3, and an annular clamping block 5 is slidably connected in the circular through groove, so that during the process of inserting the disk 4, the limiting rod 6 is pushed out to one side by the oblique insertion block that abuts against the limiting rod 6.

[0031] One end of the annular clamping block 5 is fixedly connected with a spring, and the other end of the spring is fixedly connected to one end of the circular through groove of the connecting block 3 .

[0032] It can be understood that: in order to allow the disk 4 to be limited by the limiting rod 6 after the disk 4 is inserted into the connecting block 3, a spring is fixedly connected to the annular clamping block 5, and the other end of the spring is fixedly connected to one end of the circular through groove of the connecting block 3. The limiting rod 6 can be reset through the expansion and contraction process of the spring to ensure that the oblique insertion block of the limiting rod 6 can be engaged with the slot of the disk 4.

[0033] The working principle and working process of the utility model are as follows: a plurality of connecting blocks 3 are linearly arranged on the mounting block 2, and a plurality of groups of disks 4 can be pre-assembled on the connecting blocks 3 of the mounting block 2, and then each mounting block 2 can be directly clamped on the rotating shaft 1 to realize convenient installation. In order to facilitate the installation process of the device by the staff, arc-shaped clamping plates 7 are fixedly connected to both ends of the mounting block 2, and a clamping groove that cooperates with the arc-shaped clamping plate 7 is opened on the rotating shaft 1. The staff can install the mounting block 2 with the disk 4 installed on the rotating shaft 1 as a whole through the arc-shaped clamping plates 7 at both ends. In order to increase the stability of the connection between the disk 4 and the connecting block 3 and avoid shaking, an oblique insertion block is arranged on the limiting rod 6, and a slot that cooperates with each other is opened at the corresponding position of the disk 4. When the disk 4 is inserted into the connecting block 3, it can be engaged through the mutual cooperation of the oblique insertion block and the slot. In order to ensure that the limiting rod 6 on one side will not get stuck in the process of inserting the disk 4 into the connecting block 3, a circular through groove is opened on one side of the connecting block 3, and an annular clamping block 5 is slidably connected in the circular through groove. During the downward insertion process of the disk 4, the limiting rod 6 is pushed out to one side by the oblique insertion block abutting the limiting rod 6. In order to allow the limiting rod 6 to limit the disk 4 after the disk 4 is inserted into the connecting block 3, a spring is fixedly connected to the annular clamping block 5, and the other end of the spring is fixedly connected to one end of the circular through groove of the connecting block 3. The limiting rod 6 can be reset through the expansion and contraction process of the spring, thereby ensuring that the oblique insertion block of the limiting rod 6 and the slot of the disk 4 can cooperate and engage.
