Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a sludge filter pressing mechanism with a conveying filter pressing structure. Background Art

[0002] Hospital wastewater treatment is a complex and important process, which involves multiple links and multiple technologies. Hospital wastewater mainly includes medical, domestic and fecal sewage discharged from various departments such as outpatient clinics, wards, operating rooms, and laboratories, which contains a large number of pathogens and toxic and harmful substances. Therefore, the primary goal of hospital wastewater treatment is to remove these harmful substances and ensure that the wastewater meets the discharge standards. The treatment process mainly includes pretreatment, primary treatment, secondary treatment, deep treatment and disinfection. First, the wastewater will pass through the grid well to remove soft fibers and large particles in the sewage to prevent clogging of pumps, valves, pipes and other equipment. Then, the wastewater will enter the regulating tank to adjust the water quality and water volume and ensure the continuous operation of subsequent equipment. After that, the wastewater will undergo a series of treatment processes, such as coagulation and sedimentation, biochemical treatment, etc., to remove suspended matter, organic matter and nutrients such as nitrogen and phosphorus. These treatment processes can be selected and optimized according to the specific situation of the hospital. In the biochemical treatment stage, activated sludge method, biological contact oxidation method and other technologies are usually used to use microorganisms to degrade organic matter. In addition, high-efficiency treatment technologies such as membrane bioreactors (MBR) can be used to improve the treatment effect. Finally, the wastewater will be disinfected to kill the remaining pathogens. Commonly used disinfection methods include chlorination, ozone, ultraviolet disinfection, etc. Chlorination disinfection mainly includes liquid chlorine method, sodium chlorate and chlorine dioxide method.

[0003] When treating hospital wastewater, the generated sludge needs to be filtered. Sludge filter pressing is an important part of the hospital wastewater treatment process. Its main purpose is to reduce the volume and water content of the sludge for subsequent treatment or disposal. Through filter pressing, the water in the sludge can be effectively removed to make it thicker, thereby reducing the cost of transportation and disposal. However, we consider that in the process of sludge filter pressing, plate and frame filter presses are mostly used. This method is not convenient for cleaning the filter press, which will affect the subsequent use of the filter press, and then affect the overall efficiency of sewage treatment. It is extremely inconvenient, so there is an urgent need for a sludge filter press mechanism with a conveying filter press structure to solve the above problems. Summary of the invention

[0014] When the sludge filter press mechanism with a conveying and filtering structure of the present invention is used, the sludge to be compressed is first placed in the top frame, and at this time, the space formed by each group of push plates on the conveyor belt corresponds alternately to the top frame, and the pumping plate can be moved by the cylinder to make the pumping plate gradually withdrawn from the top frame, and the sludge in the top frame will gradually fall in the middle of one group of push plates.

At this time, the cleaning rod in the bottom frame can be driven to fit with the conveyor belt, and the servo motor can be started to clean the conveyor belt. After the sludge in a group of push plates is filtered, the pressure plate is lifted. At this time, the bottom frame and the cleaning rod will be moved down, so that the pressure plate and the bottom frame are separated from the push plate, which will not hinder the movement of the push plate with the conveyor belt. The conveyor belt can be cleaned while the sludge pressure is achieved. Compared with the prior art, in the process of sludge filtering, a plate and frame filter press is mostly used. This method is not convenient for cleaning the filter press, which will affect the subsequent use of the filter press, and further affect the overall efficiency of sewage treatment. The method proposed in the present invention, through the coordinated use of various components, can clean the conveyor belt while achieving the sludge pressure, and filter the sludge during transportation.

[0015] The present invention also has the following beneficial effects:

[0016] When it is located at the top of one side of one set of push plates, the cleaning rod will be located at the bottom of the other side of the other set of push plates, forming an alternation, so that when the pressing plate is filtering the sludge in one set, the cleaning rod located at the bottom can filter the sludge in one set of push plates, and then can clean the conveyor belt in the other set of push plates moved to the lower part of the frame;

[0017] The sludge after filtration will move to one side of the carrier frame as the conveyor belt moves, and the sludge after filtration will fall into the carrier frame.
