Description

Technical Field

[0001] The utility model relates to the technical field of sludge processing equipment, in particular to a novel sludge filter press. Background Art

[0002] With the development of my country's social economy and urbanization, many industrial enterprises such as papermaking, starch, alcohol, etc. produce a lot of sludge every day in the production process. With the expansion of water supply and drainage pipelines in cities and the increase of sewage treatment plants, the sludge production will also increase.

[0003] The sludge filter press is a machine that applies mechanical force on one side of the filter medium to achieve filtration. It is mainly used to achieve solid-liquid separation of sludge.

[0004] At present, the existing sludge filter press will cause a lot of mud and water leakage during the sludge treatment process, making the treatment site dirty and smelly, thus causing secondary pollution to the environment. Secondly, it requires manual operation by staff, which will also affect the health of the staff due to the poor working environment. Utility Model Content

[0005] The purpose of the utility model is to provide a novel sludge filter press to effectively solve the above technical problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solution:

[0007] A novel sludge filter press comprises a material collecting and releasing device and a material pressing device; the material pressing device comprises a material frame and a downward pressing plate, a water outlet plate is installed on the inner wall of the material frame, a through groove is opened on the water outlet plate, a side of the through groove away from the inner wall of the material frame is shorter than a side close to the inner wall of the material frame, a water outlet is arranged at the bottom of the material frame, and the outer side of the downward pressing plate is in contact with the inner wall of the material frame.

[0008] By adopting the above technical solution, the sludge is placed in the material frame, and the lower pressure plate is controlled to squeeze the sludge downward. After the liquid in the sludge is separated, it flows out of the water outlet through the through groove on the water outlet plate. Because the outer side of the lower pressure plate fits the inner wall of the material frame, the sludge will not overflow upward from the lower pressure plate during the squeezing process, and then there will be no mud or water leakage, so that the treatment site is clean and tidy, and no secondary pollution to the environment will be caused. In addition, because the side of the through groove opening away from the inner wall of the material frame is narrower than the side close to the inner wall of the material frame, during the squeezing process of the sludge, only the liquid in the sludge can flow into the through groove on the water outlet plate, while the solid in the sludge cannot pass through, thereby achieving solid-liquid separation.

[0009] In order to further better realize the present utility model, the following setting structure is particularly adopted: the pressing device also includes a first driver for driving the lower pressing plate, an upper pressing plate arranged inside the material frame and a second driver for driving the upper pressing plate, the pressing device also includes a main machine lower beam and a main machine upper beam, the material frame is fixedly installed on the main machine lower beam, a column is connected between the main machine upper beam and the main machine lower beam, and the first driver is fixedly installed on the main machine upper beam.

[0010] By adopting the above technical solution, the first driver is used instead of manual driving to drive the lower pressure plate to extrude the sludge, which will be more efficient and have better effects. At the same time, an upper pressure plate and a second driver that drives the upper pressure plate are provided, so that the sludge can be squeezed from the upper and lower sides at the same time, and the extrusion efficiency and effect are further improved. The material frame is fixedly installed on the lower beam of the main machine so that no shaking occurs during the extrusion process.

[0011] In order to further better realize the utility model, the following setting structure is particularly adopted: there is a gap between the outer side of the upper pressing plate and the inner wall of the material frame.

[0012] By adopting the above technical solution, during the process of squeezing sludge, the squeezed liquid can, on the one hand, flow down from the gap between the upper pressing plate and the inner wall of the material frame, and then flow out from the water outlet; on the other hand, it can also directly flow into the groove on the water outlet plate, and then flow out from the water outlet. These two methods improve the efficiency of liquid outflow.

[0013] To further better implement the present invention, the following configuration is particularly adopted: both the first driver and the second driver are oil cylinders.

[0014] By adopting the above technical solution, the power of the oil cylinder is strong and the extrusion efficiency can be improved.

[0015] In order to further better realize the present utility model, the following setting structure is particularly adopted: the material collecting and unloading device includes an upper filter cloth, a first transmission mechanism for driving the upper filter cloth, a lower filter cloth, and a second transmission mechanism for driving the lower filter cloth, and the upper filter cloth is located above the lower filter cloth.

[0016] By adopting the above technical solution, the sludge is placed on the lower filter cloth, and the upper filter cloth is arranged above the sludge. The upper filter cloth and the lower filter cloth are driven to move by the first transmission mechanism and the second transmission mechanism to realize automatic transmission of the sludge. The staff can perform remote operation, and the upper and lower filter cloths will only pass the liquid and leave the solid in the filter cloth. While achieving solid-liquid separation, the separated solid can be clamped and taken out by the upper filter cloth and the lower filter cloth, without causing pollution to the working environment.

[0017] In order to further better realize the present utility model, the following setting structure is particularly adopted: the material collecting and releasing device also includes a workbench, the lower filter cloth is located above the workbench, and the workbench is higher than the top surface of the material frame.

[0018] By adopting the above technical solution, since the weight of the sludge will cause the lower filter cloth to protrude downward, making it inconvenient to transport, the workbench can support the lower filter cloth to enable it to move smoothly. At the same time, the workbench is higher than the top surface of the material frame, so that the sludge can easily enter the material frame.

[0019] In order to further better realize the present utility model, the following setting structure is particularly adopted: the first transmission mechanism and the second transmission mechanism are both composed of a plurality of fixed pulleys, the upper filter cloth is sequentially wound around the fixed pulley of the first transmission mechanism, and the lower filter cloth is sequentially wound around the fixed pulley of the second transmission mechanism.

[0020] By adopting the above technical solution, the running trajectories of the upper filter cloth and the lower filter cloth can be adjusted and controlled as needed.

[0021] In order to further better realize the utility model, the following setting structure is particularly adopted: reinforcing ribs are installed on the outer wall of the material frame.

[0022] By adopting the above technical solution, the stability of the material frame can be further enhanced.

[0023] In order to further better realize the utility model, the following setting structure is particularly adopted: the new sludge filter press also includes a hydraulic system for controlling the oil cylinder and an electrical control system for controlling the material collecting and releasing device.

[0024] By adopting the above technical solution, the hydraulic system and the electrical control system can enable the staff to operate the material pressing device away from the processing site without affecting the health of the staff.

[0025] Beneficial effects: The utility model can separate solid and liquid by arranging a water outlet plate, thereby improving the efficiency of sludge treatment; by arranging the fit between the lower pressure plate and the inner wall of the material frame, the phenomenon of mud and water leakage during sludge treatment can be solved, so that the treatment site is clean and tidy, and no secondary pollution of the environment will be caused; by arranging an electrical control system and a hydraulic system, the staff can operate the material collecting and releasing device and the material pressing device far away from the treatment site without affecting the health of the staff.

The material frame 215 is fixedly installed on the upper surface of the mainframe lower beam 219. Reinforcing ribs 221 are fixed around the material frame 215 to circumferentially reinforce the material frame 215. A water outlet plate 216 is installed on the inner wall of the material frame 215. There are two water outlet plates 216 installed on two opposite side surfaces of the inner wall of the material frame 215. A through groove 217 is opened on the water outlet plate 216. The side of the notch of the through groove 217 away from the inner wall of the material frame 215 is shorter than the side close to the inner wall of the material frame 215. A water outlet 218 is arranged at the bottom of the material frame 215. A through hole is provided in the middle of the main machine lower beam 219, in which an upper oil cylinder is installed, and an upper pressure plate 214 is installed at the upper end of the upper oil cylinder. The upper oil cylinder can drive the upper pressure plate 214 to expand and contract up and down in the material frame 215, and there is a gap between the outer side of the upper pressure plate 214 and the inner wall of the material frame 215. Four columns 222 are fixedly installed at the four corners of the main machine lower beam 219, and the upper parts of the four columns 222 are fixedly connected to the four corners of the main machine upper beam 220. A through hole is provided in the middle of the main machine upper beam 220, in which a downward pressure cylinder is installed, and a downward pressure plate 212 is installed at the lower end of the downward pressure cylinder. The downward pressure cylinder can drive the downward pressure plate 212 to expand and contract up and down in the material frame 215, and the outer side of the downward pressure plate 212 fits with the inner wall of the material frame 215. The sludge placed in the material frame 215 can achieve solid-liquid separation under the cooperative extrusion of the upper pressure plate 214 and the lower pressure plate 212. The separated liquid can either flow out directly from the through groove 217 of the water outlet plate 216 and then flow out from the water outlet 218, or first flow down from the gap between the outer side of the upper pressure plate 214 and the inner wall of the material frame 215, and then flow out from the water outlet 218, thereby improving the efficiency of liquid outflow.

[0033] A flat workbench 15 is horizontally placed in the middle of the side of the material receiving and unloading device 1. The bottom of the workbench 15 is higher than the top of the material frame 215. Rollers are installed on the four corners of the bottom of the material receiving and unloading device 1. A first transmission mechanism 11 is fixedly installed at the upper position on the same side of the material receiving and unloading device 1 as the workbench 15. The first transmission mechanism 11 is composed of five fixed pulleys. The upper filter cloth 13 is wound around the fifth fixed pulley 115. One end of the upper filter cloth 13 extends out of the fifth fixed pulley 115 and passes through the fourth fixed pulley 114, the third fixed pulley 113, the second fixed pulley 112, and the first fixed pulley 111 in sequence. A second transmission mechanism 12 is fixedly installed at the lower position on the same side of the material receiving and unloading device 1 as the workbench 15. The second transmission mechanism 12 is composed of six fixed pulleys. The cloth 14 is wound around the eleventh fixed pulley 126, one end of the lower filter cloth 14 extends out of the eleventh fixed pulley 126, and is connected to one end of the upper filter cloth 13 after passing through the tenth fixed pulley 125, the ninth fixed pulley 124, the eighth fixed pulley 123, the seventh fixed pulley 122, and the sixth fixed pulley 121 in sequence. When working, the sludge is poured onto the lower filter cloth 14 on the workbench 15, and the electrical control system 4 is started to control the first fixed pulley 111 to rotate counterclockwise and the sixth fixed pulley 121 to rotate clockwise, so that the upper filter cloth 13 and the lower filter cloth 14 can wrap the sludge and move.

[0034] The method of using the new type of sludge filter press described in the utility model is briefly described as follows: start the hydraulic system 3, so that the upper oil cylinder drives the upper pressing plate 214 to the upper limit, and the lower pressing cylinder drives the lower pressing plate 212 to retract the upper limit, start the material collection and discharge device 1, and pour the sludge onto the lower filter cloth 14. Under the dual effects of the clockwise rotation of the sixth fixed pulley 121 and the gravity of the sludge, the lower filter cloth 14 continues to move toward the direction of the material pressing device 2 with the sludge, and the fifth fixed pulley 115 rotates counterclockwise, driving the upper filter cloth 13 to move continuously to the right. At this time, the sludge is sandwiched between the upper filter cloth 13 and the lower filter cloth 14 and continues to move toward the direction of the material pressing device 2. At the same time, the material collection and discharge device 1 drives the workbench 15 thereon to move synchronously left and right. The left and right movement range of the right end of the workbench 15 does not exceed the left and right side walls of the material frame 215, so that the upper filter part 13 and the lower filter part 14 are The sludge is sandwiched and evenly spread on the upper pressing plate 214 in the material frame 215 in a zigzag shape. As the sludge increases, the upper pressing cylinder is operated to slowly shrink so that the sludge covers the entire material frame 215. The lower pressing cylinder drives the lower pressing plate 212 to press the sludge step by step. Since the lower pressing plate 212 fits the inner wall of the material frame 215, the sewage can only be discharged from the through groove 217 of the water outlet plate 216 on the inner wall of the material frame 215 and discharged through the The sludge flows out from the water outlet 218, or flows down from the gap between the lower pressure plate 212 and the inner wall of the material frame 215 and flows out through the water outlet 218. After the sludge is squeezed dry, the lower pressure cylinder drives the lower pressure plate 212 to rise, and the upper pressure cylinder drives the upper pressure plate 214 to rise, the fifth fixed pulley 115 rotates counterclockwise, and the eleventh fixed pulley 126 rotates clockwise, and the solid after solid-liquid separation is brought out of the material frame 215 together with the upper filter cloth 13 and the lower filter cloth 14.
