Description

Technical Field

[0001] This utility model belongs to the field of electrochemical water treatment technology and relates to an electromagnetically driven drum filter device. Background Technology

[0002] Electromagnetically driven drum filters are innovative devices that optimize the transmission or control system of traditional drum filters using electromagnetic technology. Their core functionality involves directly driving the drum's rotation or controlling the filter cloth's movement via an electromagnetic direct-drive motor or electromagnetic clutch, replacing the traditional mechanical transmission structure. This reduces energy loss, improves response speed, and achieves precise control. Suitable for precision machining, chemical, and pharmaceutical industries, this device efficiently filters impurities from liquids while offering advantages such as energy saving, low maintenance, and intelligent adjustment. It is particularly suitable for industrial applications requiring high filtration accuracy and stability.

[0003] For example, patent (CN208308484U) discloses a rotary drum stainless steel membrane filter device, which describes that "the rotary drum stainless steel membrane filter device is equipped with a filter cylinder, a rotating shaft, and a support. The filter cylinder is connected to the rotating shaft and fixed inside the rotary drum stainless steel membrane filter device by the support. The rotating shaft is connected to a rotary drum motor located outside the rotary drum stainless steel membrane filter device. The rotary drum motor drives the filter cylinder to rotate. The filter cylinder is a hollow cylinder with a filter screen installed on its surface. Using the above technical solution, a high-efficiency rotary drum stainless steel membrane filter device is made. The rotary drum stainless steel membrane filter device in this utility model filters undecomposed impurities in water, greatly improving the purification effect and enhancing the equipment's control over the turbidity index of circulating water."

[0004] When using the above technology, the following technical problems were found in the existing technology: When installing the filter screen, the existing electromagnetically driven drum filter device usually uses bolt connection to assemble multiple independent filter screens into a drum-shaped structure. This method has the problems of cumbersome operation and long time consumption in the actual assembly process. Since each piece needs to be aligned and the bolts tightened, it increases the labor intensity of workers. Utility Model Content

[0005] The technical problem to be solved by this utility model is that when installing the filter screen in the existing electromagnetically driven drum filter device, multiple independent filter screens are usually assembled into a drum-shaped structure by bolt connection. This method has the problems of cumbersome operation and long time consumption in the actual assembly process. Since each screen needs to be aligned and the bolts tightened, the labor intensity of workers is increased.

[0006] This utility model discloses an electromagnetically driven drum filter device, comprising a first mounting ring; multiple sets of first support plates are fixedly connected to the end of the first mounting ring; a first filter screen is fixedly connected between every two sets of first support plates; a first fixing ring is fixedly connected to the end of the multiple sets of first support plates away from the first mounting ring; the first filter screen is fixedly connected to the first fixing ring and the first mounting ring; a second mounting is provided on the outside of the first mounting ring; multiple sets of second support rods are fixedly connected to the end of the second mounting near the first mounting ring; a second filter screen is fixedly connected between every two second support rods; a second fixing ring is fixedly connected to the end of the multiple sets of second support rods away from the second mounting; the second filter screen is fixedly connected to the first mounting ring and the second fixing ring; the second fixing ring is located on the outside of the first fixing ring, and a sliding assembly is provided between the first support plate and the second support rod.

[0007] The sliding assembly includes a limiting groove; a limiting groove is formed on the inner side of the first support plate; a sliding block is fixedly connected to the lower end of the second support rod; the sliding block is located inside the limiting groove and is slidably connected to the limiting groove.

[0008] The inner side of the second fixing ring is fixedly connected to multiple sets of sealing plates.

[0009] A first sawtooth block is fixedly connected to one end of the sealing plate near the second mounting; a second sawtooth block is fixedly connected to one end of the limiting groove near the first mounting ring; the second sawtooth block and the first sawtooth block mesh with each other.

[0010] The fixing component includes a mounting plate; the first mounting ring and the second mounting are provided with mounting plates on their outer sides; a serrated ring is fixedly connected to the ends of the first mounting ring and the second mounting that are far apart from each other; the mounting plate and the serrated ring mesh with each other.

[0011] Multiple sets of threaded holes are provided on the inner sides of the first mounting ring, the second mounting ring, the mounting plate, and the serrated ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the first mounting ring and the second mounting are placed inside the drum filter device, and then the first mounting ring and the second mounting are pulled, so that the first mounting ring and the first support plate are moved away from each other. When the first mounting ring and the second mounting are pulled, the second mounting drives the sliding block to slide inside the limiting groove through the second support rod and the second fixing ring. At the same time, the structure design of multiple sets of sliding blocks and limiting grooves makes it more stable when the second mounting and the first mounting ring are pulled. Then, the first mounting ring and the second mounting are fixed on the drum filter device by the fixing components, thereby completing the rapid assembly of the first mounting ring and the second mounting, thus reducing the installation time of workers.

[0013] When the first mounting ring and the second mounting ring rotate, the first mounting ring and the second mounting ring separate to their furthest distance, causing the first sawtooth block and the second sawtooth block to mesh with each other, thereby making the device more stable when rotating.
