Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment, and in particular relates to a filter tank cleaning device. Background Art

[0002] In the sewage treatment process, filtering sewage to remove mud, sand, and other debris is an important process. Its efficiency and quality directly affect the efficiency and quality of subsequent sewage treatment. For various existing sewage treatment devices, most of them use filter nets to filter impurities, but when the filtering operation reaches a certain level, it is necessary to clean the filter net, which is often troublesome, and even the filtering operation must be temporarily interrupted. The filtering operation can only be started again after the cleaning of the filter net is completed, which greatly affects the cleaning efficiency of the filter net and the working efficiency of the filtering device. And the filtered water needs to be purified and filtered through quartz sand filter material, but the service life of ordinary quartz sand used in sewage treatment is only three to five years, and it needs to be cleaned and replaced in time.

[0003] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will be further described below in conjunction with specific implementation methods.

[0023] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are with reference to the position state of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be understood as special limitations on the technical solution provided by the utility model.

[0024] like Figure 1-4 As shown, a filter tank cleaning device includes a filter tank 1, the filter tank 1 includes a first filter space 11 and a second filter space 12, an inclined filter plate 2 is provided between the first filter space 11 and the second filter space 12, a first cleaning mechanism is provided in the first filter space 11, the first cleaning mechanism includes a plurality of inclined brush rollers 3 and a first driving assembly, the first driving assembly is used to drive the brush rollers 3 to rotate, the plurality of brush rollers 3 are matched with the filter plate 2, and are used to clean mud and sand on the filter plate 2; a second cleaning mechanism is provided in the second filter space 12, the second cleaning mechanism includes a bulldozer plate 5 and a second driving assembly, the second driving assembly is used to drive the bulldozer plate 5 to move left and right, and the bulldozer plate 5 is used to clean mud and sand at the bottom of the second filter space 12.

[0025] The first driving assembly includes a connecting belt 41 and a rotating motor 42. The connecting belt 41 is arranged between adjacent brush rollers 3. At least one rotating motor 42 is provided and is arranged on one side of the brush roller 3. An opening is provided on one side of the first filtering space 11, and the opening is arranged in cooperation with the lower end of the filter plate 2. A discharge hopper 7 is provided at the opening. The discharge hopper 7 is provided to facilitate the guide of the mud and sand filtered by the filter plate 2 to the receiving frame 10. A gate 8 and a third driving assembly 9 (a rotating motor can be used) are provided on one side of the second filtering space 12. The third driving assembly 9 is used to drive the gate 8 to open and close ( Figure 1 The gate 8 is in the closed state. Figure 2 The discharge hopper 7 and the gate 8 are arranged on the same side of the filter tank 1, and a receiving frame 10 is arranged on one side of the filter tank 1. The mud and sand discharged from the discharge hopper 7 and the gate 8 can be discharged into the receiving frame 10 for collection and transportation. A universal wheel 101 is arranged at the bottom of the receiving frame 10 to facilitate the movement of the receiving frame 10 for conveying mud and sand.

[0026] The second driving assembly includes two groups of reciprocating mechanisms 6, and the reciprocating mechanism 6 includes a forward and reverse motor 61, a driving wheel 62, a driven wheel 63, a transmission belt 64 and a slide rail 65. A slider 66 is provided between the two slide rails 65. The bulldozer 5 is arranged on one side of the slider 66, and the bulldozer 5 abuts against the bottom of the second filter space 12, so as to fully clean the mud and sand at the bottom of the filter tank 1 to the gate 8 (a support seat is provided at the bottom of the filter tank 1 in the figure, which increases the height of the filter tank 1 and facilitates the mud and sand in the second filter space 12 to fall into the receiving frame 10).

[0027] Here’s how it works:

[0028] First, close the gate 8, turn on the first drive assembly to rotate the brush roller 3, pour sewage into the first filter space 11 in the filter tank 1, and the sewage falls into the second filter space 12 after being filtered by the filter plate 2. Since most of the mud and sand in the sewage will be filtered and accumulated on the filter plate 2, the filter plate 2 is tilted and equipped with a first cleaning mechanism in the present application. Several brush rollers 3 rotate in the same direction to prevent mud and sand from clogging the filter holes on the filter plate 2, and also clean the mud and sand to the opening, so that the filtered mud and sand are introduced from the discharge hopper 7 into the receiving frame 10.

[0029] The sewage from the first filter space 11 that falls into the second filter space 12 can be directly discharged from the filter tank 1 after being purified and filtered by the quartz sand in the second filter space 12. Since the service life of the quartz sand is limited, it needs to be cleaned and replaced in time. Therefore, when it is necessary to clean the mud and sand in the second filter space 12, the third drive assembly 9 can be used to rotate and open the gate 8 (at this time, the sewage has stopped entering the filter tank 1, and the filtered and purified water in the second filter space 12 has been discharged). Then turn on the forward and reverse motor 61, the driving wheel 62, the driven wheel 63 and the transmission belt 64 start to run, the slider 66 slides on the slide rail 65, and the slider 66 drives the bulldozer 5 to run from the left side of the bottom of the second filter space 12 to the right side, and the mud and sand at the bottom of the second filter space 12 are cleaned to the gate 8, and fall into the receiving frame 10. After the cleaning is completed, the forward and reverse motor 61 rotates in the reverse direction, restores the bulldozer 5 to the left side of the bottom of the second filter space 12, and closes the gate 8.

[0030] The above content is a further detailed description of the technical solution provided in combination with the preferred implementation methods of this patent. It cannot be determined that the specific implementation of the utility model is limited to the above descriptions. For ordinary technicians in the technical field to which this patent belongs, without departing from the concept of this patent, they can also make several simple deductions or substitutions, which should be deemed to fall within the scope of protection of this patent.
