Technical Field

[0001] The utility model relates to the technical field of sewage filtering equipment, in particular to an interception screen based on MBBR. Background Art

[0002] MBBR is a technology that uses the basic principles of the biofilm method and takes advantage of the advantages of the activated sludge method to efficiently treat sewage. The interception screen is a device used to intercept garbage in sewage during the sewage treatment process to prevent the loss of garbage. The interception screen uses MBBR technology to not only enhance the sewage treatment effect, but also improve the stability of the system and the flexibility of operation.

[0003] When using the existing interception screen, it is inconvenient to clean the garbage attached to the interception screen, and the garbage attached to the interception screen will affect the filtering effect of the interception screen, thereby reducing sewage treatment efficiency, increasing maintenance costs, affecting system stability, shortening equipment life, etc., thereby increasing costs and bringing environmental and health risks.

[0004] Therefore, those skilled in the art provide an interception screen based on MBBR to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and propose an intercepting screen based on MBBR. The connecting rod drives the cleaning plate to move upward. When the cleaning plate moves upward, the garbage attached to the intercepting screen is brought up together. After the connecting rod reaches the top, the garbage on the cleaning plate falls into the garbage collection mechanism according to the slope of the cleaning plate, thereby improving the filtering effect of the intercepting screen and solving the problem that the presence of garbage on the intercepting screen causes inconvenience to the staff when cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: an MBBR-based interception screen, comprising a device body, a blocking mechanism slidably disposed inside the device body, a cleaning mechanism fixedly disposed on the front side of the device body, and a garbage collection mechanism slidably disposed on the rear side of the device body, the blocking mechanism comprising a first blocking net, fixed columns fixedly disposed on both sides of the first blocking net, and a base fixedly disposed at the bottom end of the first blocking net;

[0007] The cleaning mechanism comprises a cleaning plate, connecting rods are fixedly arranged on both sides of the top of the cleaning plate, and a plurality of tooth plates are evenly fixedly arranged on the inner side of the connecting rods.

[0008] Furthermore, support plates are fixedly provided on both sides of the outer wall of the device body, and two support columns are fixedly connected to the bottom ends of the two support plates.

[0009] Furthermore, a guide rail is provided on the rear side of the outer wall of the device body, and a screen entrance is provided on the outer walls on both sides of the device body.

[0010] Furthermore, a sliding groove is provided on the outer side of the connecting rod, and a first sliding block is slidably connected to the surface of the sliding groove.

[0011] Furthermore, a motor box is fixedly provided on the top of the device body, and a motor door is hinged on the outer wall of the motor box.

[0012] Furthermore, the garbage collection mechanism includes a garbage holding box, second sliders are fixedly provided on both sides of the garbage holding box, and a second blocking net is fixedly provided on the bottom end of the garbage holding box.

[0013] Furthermore, the output end of the motor box is fixedly connected to a rotating shaft, and one end of the rotating shaft is fixedly connected to a gear.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model proposes an intercepting screen based on MBBR. The device is provided with a cleaning plate. When the device is started, the motor starts to run. First, the motor starts to rotate forward, and the rotation of the motor drives the wheel to rotate. When the gear rotates, it engages with the tooth plate on the connecting rod, so that the connecting rod drives the cleaning plate to move upward. When the cleaning plate moves upward, the garbage attached to the intercepting net is brought up together. After the connecting rod reaches the top, the garbage on the cleaning plate falls into the garbage collection mechanism along with the slope of the cleaning plate. The staff can handle the garbage collection mechanism at any time, thereby improving the filtering effect of the intercepting screen and solving the problem of inconvenience caused to the staff during cleaning due to the presence of garbage on the intercepting net.

[0016] 2. The utility model proposes an intercepting screen based on MBBR. The device is provided with a screen inlet. After the screen has been used for a period of time, adsorbed sludge and the like are likely to exist on the screen, affecting the filtering effect of the intercepting screen. A new screen can be pushed in from the screen inlet and the old screen can be squeezed out from the other end. By providing a motor door, the later maintenance and inspection of the motor is facilitated, thereby improving the filtering effect of the intercepting screen and the convenience of the staff in later inspection and replacement of the equipment.
