Description

Technical Field

[0001] This invention relates to the field of sludge extrusion, specifically to a sludge extrusion and pressurization device for a filter press. Background Technology

[0002] In wastewater treatment plants, industrial production, and environmental governance, sludge treatment is a crucial process. Sludge typically requires dewatering via filter press to reduce its moisture content, facilitating subsequent transportation and disposal. Traditional sludge filter press equipment often relies on a single conveyor belt or fixed pressure rollers for the pressing operation. Its simple overall structure makes it difficult to achieve continuous and stable pressing action on the sludge. The dewatering process depends on manual feeding and adjustment, resulting in low automation and processing efficiency, which cannot meet the needs of continuous processing of large volumes of sludge.

[0003] Existing sludge extrusion equipment suffers from numerous defects during operation. The feeding structure is prone to sludge accumulation and uneven conveying, leading to uneven force distribution in the extrusion zone. The extrusion mechanism is often set with a fixed gap, making it impossible to dynamically adjust the extrusion force according to sludge thickness and resistance, easily resulting in insufficient or excessive extrusion. The booster transmission structure is complex and lacks linkage, with asynchronous extrusion actions on both sides, easily causing sludge deviation and leakage. Furthermore, equipment maintenance and adjustment are inconvenient, and long-term operation can lead to problems such as jamming and accelerated wear, affecting overall dewatering efficiency and equipment lifespan.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example

[0029] Please see Figures 1-7 This is a schematic diagram of some embodiments of a sludge extrusion and pressurization device for a filter press, as described in this application.

[0030] In some embodiments, the filter press sludge extrusion and pressurization equipment can be applied to scenarios such as municipal sewage treatment, industrial sludge dewatering, livestock manure treatment, and river dredging sludge drying.

Figure 1 In this embodiment, the device is used as an example for deep dewatering of sludge in a municipal wastewater treatment plant. Of course, other types of sludge treatment scenarios can also adopt a similar structure, which will not be described in detail below.

[0031] Understandable, Figure 1 The sludge extrusion and pressurization equipment of the filter press is only schematically shown, including the support frame 1, feeding assembly 2, first feeding unit 3, second feeding unit 4, sludge extrusion and pressurization assembly 5, and collection unit 6. The actual shape, size, position, and structure of these components are not subject to change. Figure 1 Limitations, the equipment may also include compared to Figure 1 More or fewer auxiliary components.

[0032] In some embodiments, the sludge extrusion and pressurization equipment of the filter press may include a support frame 1, with a feeding assembly 2 installed inside the support frame 1 for conveying sludge to the filter press; a first feeding unit 3 is provided below the feeding assembly 2 for smoothly conveying the conveyed sludge to the extrusion position; a second feeding unit 4 is provided below the first feeding unit 3 for initially extruding the sludge through cooperation with the first feeding unit 3; a sludge extrusion and pressurization assembly 5 is provided on one side of the second feeding unit 4 for gradually increasing the pressure of the sludge during the extrusion process to improve the dewatering rate; a collection unit 6 is provided below the sludge extrusion and pressurization assembly 5 for centralized collection and conveying of the sludge cake after extrusion and dewatering.

[0033] For example, the sludge extrusion and pressurization equipment of the filter press may also include a PLC control module, a moisture content detection sensor, an emergency stop protection mechanism, a filter belt cleaning spray mechanism, etc., to improve the degree of automation, dewatering stability and operational safety.

[0034] In some embodiments, the first feeding unit 3 may include a first drive motor 31, a first main drive pulley 32, a sludge conveyor belt 33, and a first driven pulley 34. Specifically: the first drive motor 31 is fixedly mounted on the outside of the support frame 1, and its output end is fixedly connected to the first main drive pulley 32; the connection between the first main drive pulley 32 and the first drive motor 31 is rotatably connected to the support frame 1, and the end of the first main drive pulley 32 away from the first drive motor 31 is rotatably connected to the inside of the support frame 1; the sludge conveyor belt 33 is sleeved on the outside of the first main drive pulley 32; both ends of the first driven pulley 34 are rotatably connected to the inside of the support frame 1, and two sets of the first driven pulley 34 are provided, with another set located between the first main drive pulley 32 and the first driven pulley 34, used to flatten one end face of the sludge conveyor belt 33 to form a stable conveying slope.

[0035] It should be noted that the sludge conveyor belt 33 is made of anti-slip, wear-resistant and corrosion-resistant polyurethane material, and the surface can be set with anti-slip texture to prevent the sludge from slipping or falling off during the conveying process; the two sets of first driven pulleys 34 cooperate with the first main drive pulley 32 to make the sludge conveyor belt 33 form a flat and stable conveying surface, ensuring that the sludge enters the squeezing area evenly.

[0036] Understandably, the installation position of the first drive motor 31 and the length and inclination angle of the sludge conveyor belt 33 shown in the figure are only schematic and can be adjusted according to the sludge processing capacity and the matching height of the filter press, and are not limited here.

[0037] In some embodiments, the second feeding unit 4 may include a second drive motor 41, a second main drive pulley 42, a first auxiliary extrusion belt 43, a second driven pulley 44, an auxiliary drive pulley 45, and a guide slide rod 46. Specifically: the second drive motor 41 is fixedly mounted on the outside of the support frame 1, and its output end is fixedly connected to the second main drive pulley 42; the connection between the second drive motor 41 and the second main drive pulley 42 is rotatably connected to the support frame 1; the first auxiliary extrusion belt 43 is sleeved on the outside of the second main drive pulley 42, and the second driven pulley 44 is disposed inside the first auxiliary extrusion belt 43; two sets of auxiliary drive pulleys 45 are arranged vertically inside the first auxiliary extrusion belt 43, and the second driven pulley 44 and the auxiliary drive pulley 45 support the first auxiliary extrusion belt 43 to form an inclined surface, with the inclined surface having the same inclination angle as the inclined surface supported by the first driven pulley 34 and the first main drive pulley 32 on the sludge conveyor belt 33, and the two inclined surfaces being close in distance, for continuous clamping and extrusion of the sludge.

[0038] The guide slide rod 46 is fixedly installed inside the support frame 1. The two ends of the auxiliary drive pulley 45 are respectively slidably connected to the guide slide rod 46. The support frame 1 is provided with grooves for the two ends of the auxiliary drive pulley 45 to slide, so that the auxiliary drive pulley 45 can move up and down along the guide slide rod 46, and the extrusion gap can be dynamically adjusted in conjunction with the sludge extrusion and pressurization assembly 5.

[0039] It should be noted that the first auxiliary extrusion belt 43 is made of a highly elastic and tensile-resistant material and runs synchronously and in the same direction as the sludge conveyor belt 33 to avoid shearing damage to the sludge, while ensuring that the sludge passes stably between the two belts and is initially dewatered.

[0040] In some other embodiments, the auxiliary drive pulley 45 may also be driven by an electric slider, without being limited to a pure sliding guide structure, as long as the position of the inclined surface of the first auxiliary extrusion belt 43 can be adjusted.

[0041] In some embodiments, the sludge extrusion and pressurization assembly 5 may include a first connecting plate 51, a drive piston rod 52, a reset auxiliary spring 53, a first transmission connecting pipe 54, a second transmission connecting pipe 55, a third transmission connecting pipe 56, an auxiliary mounting plate 57, a fourth transmission connecting pipe 58, a driven piston rod 59, and a guide telescopic rod 514. Wherein: the first connecting plate 51 is fixedly installed on the lower side of the auxiliary drive pulley 45, and the middle position of the lower side of the first connecting plate 51 is fixedly connected to the drive piston rod 52; a reset auxiliary spring 53 is sleeved on the outer side of the drive piston rod 52, one end of the drive piston rod 52 is slidably connected to the inner side of the first transmission connecting pipe 54, and both ends of the drive piston rod 52 are respectively fixedly connected to the lower side of the first connecting plate 51 and the end of the first transmission connecting pipe 54 away from the second transmission connecting pipe 55; one end of the first transmission connecting pipe 54 is connected to the second transmission connecting pipe 55, and one end of the second transmission connecting pipe 55 is connected to the middle position of the third transmission connecting pipe 56; the third transmission connecting pipe 56 is U-shaped, one end of the third transmission connecting pipe 56 is fixedly connected to the auxiliary mounting plate 57 on the outer side, and one end of the third transmission connecting pipe 56 is connected to the fourth transmission connecting pipe 58; the upper end of the driven piston rod 59 is slidably connected to the inner side of the fourth transmission connecting pipe 58, forming a closed hydraulic / pneumatic linkage transmission structure.

[0042] The sludge extrusion and pressurization assembly 5 also includes a push plate 510, a second connecting plate 511, a rolling wheel 512, and a second auxiliary extrusion belt 513. Wherein: the guide telescopic rod 514 is fixedly connected at both ends to the lower side of the auxiliary mounting plate 57 and the upper side of the push plate 510 respectively; one side of both ends of the push plate 510 is fixedly connected to the second connecting plate 511, and the inner ends of the second connecting plate 511 are rotatably connected to the rolling wheels 512; the outer side of the rolling wheels 512 slides against the inner side of the second auxiliary extrusion belt 513, and two sets of rolling wheels 512 are provided and symmetrically arranged on the second connecting plate 511; the inner side of the second auxiliary extrusion belt 513 slides against the outer side of the second connecting plate 511 and the outer side of the rolling wheels 512, and two sets of the second auxiliary extrusion belt 513 are provided and respectively located on the lower side of the inclined surface supported by the second driven pulley 44 and the auxiliary drive pulley 45 on the first auxiliary extrusion belt 43, and on the upper side of the inclined surface supported by the first driven pulley 34 and the first main drive pulley 32 on the sludge conveyor belt 33; two sets of auxiliary mounting plates 57 are provided and symmetrically arranged on the outer sides of both ends of the third transmission connecting pipe 56.

[0043] It should be noted that the driving piston rod 52, the first transmission connecting pipe 54, the second transmission connecting pipe 55, the third transmission connecting pipe 56, the fourth transmission connecting pipe 58, and the driven piston rod 59 constitute a linkage boosting mechanism. Hydraulic oil or gas can be used as the transmission medium to achieve "one place is pressurized and multiple places are pressurized simultaneously", so that the second auxiliary extrusion belt 513 exerts a uniform and progressively increasing pressure on the sludge.

[0044] The diagram illustrates the transmission direction between the driving piston rod 52 and the driven piston rod 59. It is understood that the transmission medium can also be other inert fluids to achieve stable pressure transmission. The type of medium is not limited here, as long as synchronous pressurization can be achieved.

[0045] Working principle: Initial state: The equipment is in standby mode, the first drive motor 31 and the second drive motor 41 are not started, the sludge conveyor belt 33 and the first auxiliary extrusion belt 43 are stationary; the reset auxiliary spring 53 is in the naturally extended state, the drive piston rod 52 and the driven piston rod 59 are in the initial position, and the second auxiliary extrusion belt 513 maintains a preset gap with the sludge conveyor belt 33 and the first auxiliary extrusion belt 43 to facilitate sludge entry.

[0046] Sludge conveying and preliminary compression: The feeding assembly 2 evenly conveys the sludge to the sludge conveyor belt 33. The first drive motor 31 drives the first main drive pulley 32 to rotate. The sludge conveyor belt 33, in cooperation with the first driven pulley 34, feeds the sludge into the compression slope. The second drive motor 41 synchronously drives the second main drive pulley 42 to rotate. The first auxiliary compression belt 43 runs in the same direction as the sludge conveyor belt 33. The two slopes form a clamping channel to perform preliminary compression and dewatering of the sludge.

[0047] The compression and pressurization process: When the sludge passes through the two inclined planes, the thickness and resistance push the auxiliary drive pulley 45 to slide downward along the guide slide bar 46. The auxiliary drive pulley 45 presses down on the first connecting plate 51, causing the drive piston rod 52 to move downward and compress the reset auxiliary spring 53. The drive piston rod 52 transmits the pressure to the first transmission connecting pipe 54, the second transmission connecting pipe 55, and the third transmission connecting pipe 56, pushing the driven piston rod 59 in the fourth transmission connecting pipe 58 to extend downward. The driven piston rod 59 pushes the push plate 510 and the second connecting plate 511 to move downward, so that the second auxiliary compression belt 513 moves closer to the sludge conveyor belt 33 and the first auxiliary compression belt 43 at the same time, reducing the compression gap and increasing the compression force to achieve deep pressurization and dewatering of the sludge.

[0048] Dewatering and resetting process: After the sludge is squeezed and leaves the squeezing area, the pressure on the auxiliary drive pulley 45 decreases, the reset auxiliary spring 53 releases elastic potential energy, and pushes the drive piston rod 52 and the first connecting plate 51 to reset upwards. This causes the driven piston rod 59, the push plate 510, the second connecting plate 511 and the second auxiliary squeezing belt 513 to return to their initial positions, waiting for the next round of sludge squeezing.

[0049] Sludge collection: The sludge cake after squeezing and dewatering falls into the lower collection unit 6, which then transports it to the sludge storage area or subsequent treatment equipment to complete the entire sludge squeezing, pressurizing and dewatering process.
