Description

Technical Field

[0001] This utility model relates to the field of water treatment device technology, and in particular to a novel drum-type water treatment device. Background Technology

[0002] In water treatment, it is generally necessary to first remove particulate or stringy impurities from the water before fine or chemical treatment. During impurity removal, regular backwashing is often required to remove impurities or particles from the filter screen, which can easily interrupt normal filtration and waste a large amount of backwash water. A utility model patent with publication number CN205699730 U discloses a drum-type water treatment device that uses a horizontal drum for water treatment. However, the working principle of this device relies on the water source impacting the drum with a filter screen to filter impurities. During this process, the drum can only partially contact the water source circumferentially, resulting in low filter screen utilization and short contact time between the water and the drum. A large amount of unfiltered water falls into the collection tank and needs to be re-extracted and filtered, leading to low filtration efficiency and energy waste.

[0003] Therefore, considering the aforementioned technical problems, it is necessary to provide a new technical solution. Utility Model Content

[0004] The purpose of this invention is to provide a new type of drum-type water treatment device with higher water treatment efficiency and equipment utilization.

[0005] To solve the above-mentioned technical problems, this utility model provides a novel drum-type water treatment device, the specific technical solution of which is as follows:

[0006] A novel drum-type water treatment device includes a treatment tank and a drum installed in the treatment tank. The drum is vertically oriented axially, and the outside of the drum is covered with a filter screen. The inside and outside of the drum are separated by the filter screen to facilitate the filtration of impurities in the water to be treated.

[0007] The treatment tank is equipped with a drive motor on the outside, and the drum is connected to the drive motor so that the drive motor can drive the drum to rotate.

[0008] The bottom of the drum is provided with a water outlet. One end of the water outlet is connected to the inside of the filter screen of the drum, and the other end extends out of the treatment tank to facilitate the discharge of the treated water.

[0009] The drum is also equipped with a backwash pipe connected to a clean water source. The backwash pipe is rotatably connected to the drum and has flushing holes pointing towards the filter screen.

[0010] Preferably, a drive shaft is fixedly installed on the upper end of the drum, one end of which extends out of the top of the treatment tank and is connected to the drive motor via a synchronous pulley. The drum rotates axially around the drive shaft through the cooperation of the drive motor and the drive shaft.

[0011] Preferably, the drive shaft is a hollow shaft, and the backwash pipe is rotatably installed inside the drive shaft. One end of the backwash pipe extends into the inside of the drum from the top of the drum, and the other end is connected to the clean water source. The flushing hole is opened on the side wall of the part of the backwash pipe located inside the drum.

[0012] Preferably, the upper part of the treatment tank is provided with an inlet for injecting water to be treated into the treatment tank, and the height of the inlet is higher than the height of the plane where the top of the drum is located.

[0013] Preferably, the bottom of the treatment tank is provided with a drain outlet for discharging impurities, and an on / off valve is installed at the drain outlet to facilitate water collection and sewage discharge in the treatment tank.

[0014] Preferably, a baffle plate is provided above the treatment pool, and the drive motor is located above the baffle plate to prevent water splashing from affecting the motor. The drive end of the drive motor passes through the baffle plate and is connected to the roller.

[0015] Preferably, the treatment tank and the roller are multiple sets that are adapted to each other. Each set of treatment tanks is connected sequentially from front to back according to the direction of the treated water flow. The outlet of the roller in the front treatment tank is connected to the inlet of the adjacent treatment tank behind it, and the mesh size of the filter screen on the roller in each set increases sequentially from front to back.

[0016] Preferably, the sewage outlet of the treatment tank is unidirectionally connected to the inlet of the adjacent treatment tank in front to facilitate the recycling treatment of sewage containing impurities.

[0017] This utility model discloses a novel drum-type water treatment device, which has the following beneficial effects:

[0018] This novel drum-type water treatment device changes the contact method between the drum and the water to be treated by altering the drum's installation method. This increases the contact area and contact time between the water to be treated and the drum filter screen in the treatment tank, enabling more efficient water treatment. The drum can be submerged in the treatment tank, resulting in higher filter screen utilization and a longer service life. In addition, the internal backwashing structure of the drum allows for reverse washing of the filter screen from the inside, causing adhering impurities to flow into the treatment tank. This prevents impurities from breaking through the filter screen after prolonged filtration, further improving the filtration effect and extending the service life of the treatment equipment, while reducing efficiency waste caused by maintenance and cleaning.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0024] Please see Figure 1 A novel drum-type water treatment device includes a treatment tank 1 and a drum 2 installed in the treatment tank. The drum is vertically axially arranged, and the outside of the drum 2 is covered with a filter screen. The inside and outside of the drum are separated by the filter screen to facilitate the filtration of impurities in the water to be treated.

[0025] The treatment tank is equipped with a drive motor 4, and the drum 2 is connected to the drive motor 4 so that the drive motor can drive the drum to rotate.

[0026] The bottom of the roller 2 is provided with a water outlet 21. One end of the water outlet is connected to the inner side of the filter screen of the roller, and the other end extends out of the treatment tank to facilitate the discharge of the treated water.

[0027] The drum is also equipped with a backwash pipe 42 connected to a clean water source. The backwash pipe is rotatably connected to the drum and has a flushing hole pointing towards the filter screen.

[0028] A drive shaft 41 is fixedly installed on the upper end of the drum 2. One end of the drive shaft extends out of the top of the treatment tank and is connected to the drive motor through a synchronous wheel. The drum rotates around the drive shaft axially through the cooperation of the drive motor and the drive shaft.

[0029] The drive shaft 41 is a hollow shaft, and the backwash pipe 42 is rotatably installed inside the drive shaft. One end of the backwash pipe extends into the inside of the drum from the top of the drum, and the other end is connected to the clean water source. The flushing hole is opened on the side wall of the part of the backwash pipe located inside the drum.

[0030] The upper part of the treatment tank 1 is provided with a water inlet 11 for injecting water to be treated into the treatment tank, and the height of the water inlet is higher than the height of the plane where the top of the drum is located.

[0031] The bottom of the treatment tank 1 is provided with a drain outlet 12 for discharging impurities, and an on / off valve 3 is installed at the drain outlet to facilitate water collection and sewage discharge in the treatment tank.

[0032] A baffle plate 13 is provided above the treatment pool 1. The drive motor is located above the baffle plate to prevent water splashing from affecting the motor. The drive end of the drive motor passes through the baffle plate and is connected to the roller.

[0033] In actual use, a treatment tank 1 and a roller 2 are used as a group. Multiple groups of treatment devices can be used. The treatment tanks in each group are connected from front to back according to the direction of the treated water flow. The outlet of the roller in the front treatment tank is connected to the inlet 11 of the adjacent treatment tank behind. The mesh size of the filter screen on the roller in each group increases from front to back.

[0034] The sewage outlet of the treatment tank 1 is unidirectionally connected to the inlet 11 of the adjacent treatment tank in front, so as to facilitate the recycling treatment of sewage containing impurities.

[0035] In this embodiment, the novel drum-type water treatment device injects water to be treated into the treatment tank 1 through the inlet 11. At this time, the on-off valve 3 remains closed, the drum rotates, and the water flows out through the outlet after being filtered by the filter screen. Impurities are not adsorbed on the filter screen under the action of centrifugal force. At the same time, the inflow rate is ensured to be greater than the outflow rate, so that the water level in the treatment tank gradually rises until it covers the drum 2 (both ends of the drum are sealed to prevent water leakage), thereby increasing the contact area between the water to be treated and the drum filter screen. When the water level reaches a specific height or after a set time, the on-off valve 3 opens to discharge the sewage from the bottom of the treatment tank until the water level drops to a reasonable height. The on-off valve then closes and is repeatedly opened and closed to control the water level. During this process, the drive motor 4 drives the transmission shaft 41 to rotate, thereby driving the drum to rotate. The backwash pipe located in the transmission shaft can also rotate relative to the drum, and the filter screen is rinsed from the inside of the drum through the rinsing holes on the backwash pipe, washing the impurities adhering to the filter screen into the treatment tank.

[0036] The beneficial effects of this utility model are as follows: by changing the installation method of the drum, the contact method between the drum and the water to be treated is changed, which increases the contact area and contact time between the water to be treated and the drum filter screen in the treatment tank. This enables more efficient water treatment. The drum can be submerged in the treatment tank, resulting in higher filter screen utilization and an effective extension of service life. At the same time, combined with the backwashing structure inside the drum, the filter screen can be backwashed from the inside, causing adhering impurities to flow into the treatment tank. This prevents impurities from breaking through the filter screen after long-term filtration, further improving the filtration effect and the service life of the treatment equipment, and reducing the efficiency waste caused by maintenance and cleaning.

[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications and variations to the above embodiments within the scope of the present invention.
