Description

Technical Field

[0001] This utility model relates to the field of sludge filter press technology, and in particular to a belt sludge filter press. Background Technology

[0002] Sludge dewatering is a highly efficient solid-liquid separation technology that uses mechanical pressure to squeeze and separate water from sludge, forming a sludge cake with low water content. The process typically includes pretreatment (adding flocculants to promote particle aggregation), gravity dewatering, wedge pre-compression, and multi-stage dewatering. It is widely used in environmental protection, mining, and other fields to achieve sludge reduction and harmless treatment, reduce transportation and disposal costs, and is a key piece of equipment for wastewater treatment and resource recovery.

[0003] Existing sludge filter presses often suffer from damage to the pressure belts caused by hard objects such as stones and metals in the sludge during filtration. This leads to frequent belt replacements and maintenance, significantly increasing operating costs. Furthermore, sludge can adhere to the pressure belt after filtration, potentially preventing water from passing through and draining. To overcome these drawbacks, this invention provides a belt filter press for sludge. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a belt sludge filter press.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a belt sludge filter press, comprising a base plate, a processing chamber fixedly connected to the top of the base plate, a pressure roller rotatably connected inside the processing chamber, a rotating seat fixedly connected to the top of the base plate, a conveying roller rotatably connected to the rotating seat, a pressure belt provided on the conveying roller and the pressure roller, a power component provided on one side of the rotating seat, a filtration component provided at the top of the processing chamber, a cleaning component provided on one side of the processing chamber, sludge discharge components provided on both sides of the base plate, a drain outlet provided at the bottom of the base plate, and a control panel fixedly connected to one side of the processing chamber.

[0006] Furthermore, the power assembly includes a geared motor fixedly connected to one side of the rotating seat, and the output end of the geared motor passes through the rotating seat and is fixedly connected to one end of the conveying roller.

[0007] Furthermore, the filter assembly includes a filter chamber fixedly connected to the top of the processing chamber, a filter plate fixedly connected inside the filter chamber, an inclined block fixedly connected to the bottom of the filter chamber, and a conveying pipe fixedly connected to the outlet of the filter chamber, one end of the conveying pipe penetrating the processing chamber and located inside the pressure belt.

[0008] Furthermore, the cleaning assembly includes a water pipe fixedly connected to one side of the processing chamber, a plurality of high-pressure nozzles fixedly connected to the water pipe, one end of the water pipe passing through the processing chamber and located outside the processing chamber, and a valve fixedly connected to the water pipe and located outside the processing chamber.

[0009] Furthermore, the slag discharge assembly includes a support plate that is fixedly connected to both sides of the base plate, and a V-shaped plate is fixedly connected to the top of the support plate.

[0010] Furthermore, support legs are fixedly connected to the four corners of the bottom of the base plate.

[0011] The beneficial effects of this utility model are:

[0012] In use, this utility model uses a filter assembly to filter the sludge that needs to be pressure filtered, filtering out hard objects such as stones and metals, thereby preventing these hard objects from damaging the pressure belt during sludge pressure filtration. The high-pressure nozzle on the water pipe removes the sludge adhering to the surface of the pressure belt, preventing the sludge from clogging the holes on the pressure belt and thus preventing water from being discharged.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3 As shown, a belt sludge filter press is disclosed, comprising a base plate 1, a processing chamber 2 fixedly connected to the top of the base plate 1, a pressure roller 3 rotatably connected inside the processing chamber 2, a rotating seat 4 fixedly connected to the top of the base plate 1, a conveying roller 5 rotatably connected to the rotating seat 4, a pressure belt 6 provided on the conveying roller 5 and the pressure roller 3, a power component provided on one side of the rotating seat 4, a filter component provided at the top of the processing chamber 2, a cleaning component provided on one side inside the processing chamber 2, sludge discharge components provided on both sides of the base plate 1, a drain outlet 19 opened at the bottom of the base plate 1, and a control panel 17 fixedly connected to one side of the processing chamber 2.

[0021] As shown in the figure, the power assembly includes a geared motor 7 fixedly connected to one side of the rotating seat 4. The output end of the geared motor 7 passes through the rotating seat 4 and is fixedly connected to one end of the conveying roller 5, and is used to provide power for the sludge pressing and filtration.

[0022] As shown in the figure, the filter assembly includes a filter chamber 8 fixedly connected to the top of the processing chamber 2, a filter plate 9 fixedly connected inside the filter chamber 8, an inclined block 10 fixedly connected to the bottom of the filter chamber 8, and a conveying pipe 11 fixedly connected to the outlet of the filter chamber 8. One end of the conveying pipe 11 passes through the processing chamber 2 and is located inside the pressure belt 6, and is used to filter out hard objects such as stones and metals in the sludge.

[0023] As shown in the figure, the cleaning assembly includes a water pipe 14 fixedly connected to one side of the processing chamber 2. Several high-pressure nozzles 16 are fixedly connected to the water pipe 14. One end of the water pipe 14 passes through the processing chamber 2 and is located outside the processing chamber 2. A valve 15 is fixedly connected to the water pipe 14 and located outside the processing chamber 2 for removing sludge attached to the pressure belt 6.

[0026] Working principle: When using the device, first check if the entire device is intact. After the check is completed, the operator starts the reduction motor 7 through the control panel 17. The reduction motor 7 drives the conveyor roller 5 to rotate, thereby moving the pressure belt 6 and rolling the pressure roller 3. Then, connect the external water source to the water pipe 14. After the connection is completed, pour the sludge to be pressed into the filter chamber 8. The sludge in the filter chamber 8 is filtered by the filter plate 9 to remove stones, metal and other hard objects in the sludge. After filtration, it enters the conveying pipe 11 through the inclined block 10, thereby conveying it to the inside of the pressure belt 6. The sludge is squeezed by the pressure roller 3, and the squeezed water is discharged through the drain port 19. The squeezed filter residue is actively passed by the V-shaped plate 13 and discharged through both sides of the V-shaped plate 13. During the movement of the pressure plate 3, the valve 15 on the water pipe 14 is opened, and water flows into the water pipe 14. Then, the water is sprayed out through the high-pressure nozzle 16 to clean the pressure belt 6 and remove the sludge on the pressure belt 6.
