Description

Technical Field

[0001] This invention relates to the field of river silt removal technology, specifically to a river silt drying device. Background Technology

[0002] During river dredging, the dredged silt is typically transported to a fixed location via pipelines for drying. A belt filter press is usually used to filter the silt in stages, ultimately transforming it into mud blocks with lower water content. However, before this, the belt filter press needs to pre-dewater the silt with higher water content by passing it through a gravity zone dewatering device and a wedge zone dewatering device. This reduces the water content of the silt to a certain level before the mutual pressure between the filter belts can be used to transform the silt into mud blocks with lower water content. The gravity zone dewatering device mainly utilizes the gravity of water, allowing it to pass through the filter belt below to separate the water from the silt. Therefore, the speed of the filter belt is generally slow to ensure the initial filtration effect of water in the silt, which is a significant factor affecting the working efficiency of the belt filter press, resulting in lower overall efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a river silt drying device, which solves the problem that the gravity zone dewatering device of the existing belt filter press has a slow dewatering speed for silt.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A river silt drying device includes a frame as a supporting carrier, a filter belt mechanism for conveying silt is driven on the frame, and a pressure mechanism that cooperates with the filter belt mechanism to press the silt.

[0006] The pressure mechanism includes a conveyor chain assembly disposed on the top of the frame, a plurality of chamber assemblies fixed on the conveyor chain assembly for forming closed chambers on the surface of the filter belt mechanism, a plurality of mounting rods fixed on the conveyor chain assembly, pressure assemblies elastically mounted and slidably disposed within the chamber assemblies on the mounting rods, a drive assembly fixed on the frame for driving the pressure assemblies to crush the sludge on the surface of the filter belt mechanism, and a cleaning assembly for cleaning the mud on the surface of the pressure assembly at the end of the pressure assembly that contacts the surface of the filter belt mechanism.

[0007] Preferably, the conveyor chain assembly is vertically fixed to multiple support columns on the frame, and multiple rotating rollers driven by belts are rotatably mounted on the multiple support columns. Two symmetrically arranged conveyor chain bodies are driven on the multiple rotating rollers, and a motor for driving the rotating rollers is fixed on one of the support columns.

[0008] Preferably, the chamber assembly includes multiple fixing rods fixed to the conveyor chain body, and a sealing plate for pressing against the surface of the filter belt of the filter belt mechanism is fixed on the fixing rods. The two ends of the sealing plate are slidably connected to the surface of the frame.

[0009] Preferably, the pressure assembly includes two symmetrically arranged slide rods that are slidably mounted on the mounting rod, and a pressure block that is slidably mounted between two adjacent sealing plates at the bottom of the slide rod, with both ends of the pressure block slidably connected to the surface of the frame.

[0010] Preferably, the drive assembly includes a mounting base fixed to one end of the slide bar facing the middle of the conveyor chain body, a return spring between the mounting base and the mounting rod, a roller rotatably mounted on the mounting base, multiple brackets fixed on the frame, and drive seats that are tactilely connected to the rollers fixed on the multiple brackets. The bottom of the drive seat is provided with a guide slope for driving the rollers to move toward the surface of the filter belt mechanism, and the bottom of the drive seat is also provided with a horizontal surface that smoothly transitions with the guide slope.

[0011] Preferably, an adjustment component for adjusting the pressure of the pressure block on the surface of the filter belt mechanism is provided between the slide rod and the pressure block. The adjustment component includes a connecting rod fixed to the bottom of the slide rod, a limit block fixed to the top of the connecting rod, a slide cylinder fixed to the pressure block slidably connected to the bottom of the connecting rod, an adjustment block threadedly connected to the connecting rod, and a pressure spring provided between the adjustment block and the slide cylinder.

[0012] Preferably, the cleaning assembly includes a slide plate that is vertically slidably disposed within the pressure block, a plurality of cleaning plates that slide through the bottom of the pressure block are fixed to the bottom of the slide plate, a limiting rod that slides through the top of the pressure block is fixed to the top of the slide plate, and a cleaning spring is provided between the top of the slide plate and the top wall of the pressure block.

[0013] Preferably, the drive assembly is further provided with a vibration component that works with the cleaning assembly to drive the pressure assembly to vibrate. The vibration component includes a mounting surface that is inclined downwards at the end of the drive seat away from the guide slope. Multiple top plates are fixed on the mounting surface in a horizontal direction, and rollers are rolled on the multiple top plates.

[0014] Compared with the prior art, the present invention provides a river silt drying device, which has the following beneficial effects:

[0015] The pressure component and chamber component installed on the conveyor chain assembly, through the action of the drive component, enable the pressure component to automatically squeeze the sludge located in the chamber component, thereby accelerating the dewatering and drying process of the sludge. This increases the conveying speed of the filter belt on the filter belt mechanism, shortens the overall drying cycle of the sludge, and improves processing efficiency. Furthermore, in conjunction with the cleaning component and the shaking component, the bottom surface of the pressure component is cleaned after the sludge has been compressed, keeping it clean and preventing the continuous accumulation of sludge on the pressure component, which would gradually affect the filtration effect of the sludge. This achieves the goal of improving the dewatering efficiency of the gravity zone of the belt filter press.

[0016] Multiple cleaning plates are slidably installed on the bottom surface of the compaction block. The elastic force of the cleaning spring causes the multiple cleaning plates to extend from the bottom surface of the compaction block that has been pressed with silt, thereby reducing the adhesion area and adhesion of the silt, causing it to fall off under the action of gravity. Furthermore, the rolling of rollers on multiple top plates causes the compaction block to vibrate, thereby further accelerating the detachment of the silt and achieving the function of self-cleaning.

[0017] The drive assembly mounted on the frame utilizes the guide slope and horizontal surface on the mounting base that are connected to the rollers to automatically press the sludge on the surface of the filter belt when the pressure assembly moves to the position corresponding to the filter belt on the filter belt mechanism. This allows it to work in conjunction with the filter belt to filter the sludge, making the process more convenient and reliable.

[0018] The adjusting component located between the slide bar and the pressure block allows the pressure block to maintain a compacting effect on sludge of different thicknesses, preventing the pressure component from being damaged by excessive resistance from thicker sludge, and also preventing the inability to effectively filter smaller amounts of sludge, thus improving the stability of the device.

Detailed Implementation

[0029] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0030] Example 1

[0031] Figures 1-4 , Figures 6-7 In one embodiment of the present invention, the gravity zone dewatering device of the existing belt filter press is further improved to accelerate the separation speed of water and sludge in the zone, improve the overall working efficiency of the belt filter press, and reduce the working cycle of converting sludge into mud blocks with lower water content.

[0032] A river silt drying device includes a frame 1 as a supporting carrier. A filter belt mechanism 2 for transporting silt is driven on the frame 1. The frame 1 and the filter belt mechanism 2 are existing technologies and together constitute the gravity zone dewatering device of a belt filter press in the prior art. The filter belt mechanism 2 includes a filter belt that is driven to move. Silt with water is transported from one end to the other through the filter belt on the filter belt mechanism 2. Under the action of gravity, the water in the silt gradually passes through the filter belt, achieving preliminary filtration of the water, thereby gradually reducing the moisture content of the silt. The frame 1 is provided with a pressure mechanism 3 that cooperates with the filter belt mechanism 2 to press the silt. The pressure mechanism 3 is used to cooperate with the driven filter belt. The two move synchronously and achieve preliminary pressing of the silt on the surface of the filter belt on the filter belt mechanism 2, accelerating the filtration of water in the silt, thereby improving the dewatering efficiency of the gravity zone dewatering device of the belt filter press.

[0033] The pressure mechanism 3 includes a conveyor chain assembly 31 mounted on the top of the frame 1. The conveying speed of the conveyor chain assembly 31 is kept as consistent as possible with the speed of the filter belt on the filter belt mechanism 2 to facilitate the normal operation of other subsequent parts. Multiple chamber assemblies 32 are fixed on the conveyor chain assembly 31 to form closed cavities on the surface of the filter belt mechanism 2. Multiple mounting rods 33 are fixed on the conveyor chain assembly 31, and pressure assemblies 34 are elastically mounted and slidably disposed within the chamber assemblies 32 on the mounting rods 33. A drive assembly 35 is fixed on the frame 1 to drive the pressure assemblies 34 to compact the sludge on the surface of the filter belt mechanism 2. When the chamber assemblies 32 move to the surface of the filter belt mechanism 2 under the drive of the conveyor chain assembly 31 and cover the sludge, the chamber assemblies 32 cooperate with the pressure assemblies 34, allowing the pressure assemblies 34 to compact the sludge located within the chamber assemblies 32 on the filter belt mechanism 2 under the drive of the drive assembly 35. The chamber assemblies 32 then... The sludge is placed in a relatively enclosed space to ensure the pressing effect of the pressure component 34 on the sludge, preventing the sludge from flowing out from the gaps of other parts under pressure, thereby reducing the pressure on the sludge. Thus, the pressure of the pressure component 34 accelerates the dewatering and drying speed of the sludge. The end of the pressure component 34 that contacts the surface of the filter belt mechanism 2 is provided with a cleaning component 36 for cleaning mud from the surface of the pressure component 34. The cleaning component 36 cleans the surface of the pressure component 34 after the sludge has been pressed, preventing mud from continuously adhering to the surface of the pressure component 34 and ultimately affecting the pressing effect on the sludge. Thus, through the cooperation of the above structures, the sludge on the surface of the filter belt mechanism 2 is squeezed, improving the sludge dewatering efficiency, and the surface of the pressure component 34 is automatically cleaned, thereby increasing the transmission speed of the filter belt on the filter belt mechanism 2, increasing the overall dewatering speed of the belt filter press, and shortening the sludge dewatering cycle.

[0034] As a preferred technical solution in this embodiment, the conveyor chain assembly 31 is vertically fixed to multiple support columns 311 on the frame 1. Multiple rotating rollers 312 driven by belts are rotatably mounted on the multiple support columns 311. Two symmetrically arranged conveyor chain bodies 313 are driven on the multiple rotating rollers 312. The conveyor chain bodies 313 can be existing structures such as chains, realizing the fixing and transmission of the mounting rod 33 and the chamber assembly 32. One of the support columns 311 is fixed with a motor 314 for driving the rotating rollers 312 to rotate. Through the drive of the motor 314, the transmission speed of the conveyor chain body 313 is the same as the transmission speed of the filter belt on the filter belt mechanism 2. Thus, the sludge on the filter belt mechanism 2 is squeezed through the chamber assembly 32 and the pressure assembly 34, thereby improving the dewatering and drying efficiency of the sludge.

[0035] As a preferred technical solution in this embodiment, the chamber assembly 32 includes multiple fixing rods 321 fixed on the conveyor chain body 313. The fixing rods 321 are fixed with sealing plates 322 for pressing against the surface of the filter belt of the filter belt mechanism 2. The two ends of the sealing plates 322 are slidably connected to the surface of the frame 1. Through the two adjacent sealing plates 322 and the surface of the frame 1 located at both ends, a relatively sealed cavity is formed on the surface of the filter belt of the filter belt mechanism 2. This facilitates the pressure assembly 34 to squeeze the sludge located in the chamber assembly 32, thereby squeezing the sludge, accelerating the dewatering speed of the sludge, and improving the overall drying efficiency of the belt filter press for sludge.

[0036] As a preferred technical solution in this embodiment, the pressure assembly 34 includes two symmetrically arranged slide rods 341 that are slidably mounted on the mounting rod 33. The bottom of the slide rods 341 is provided with a pressure block 342 that is slidably mounted between two adjacent sealing plates 322. The two ends of the pressure block 342 are slidably connected to the surface of the frame 1. The slide rods 341 are slid up and down by the drive assembly 35, so that the pressure block 342 moves downward and presses the sludge located in the chamber assembly 32. Since the two ends of the pressure block 342 are slidably connected to the surface of the frame 1, the squeezed sludge cannot overflow from between the pressure block 342 and the frame 1, so that the sludge is subjected to a certain pressure, thereby accelerating the separation of water in the sludge and improving the drying efficiency of the sludge.

[0037] As a preferred technical solution in this embodiment, the drive assembly 35 includes a mounting base 351 fixed to one end of the slide rod 341 facing the middle of the conveyor chain body 313. A return spring 352 is provided between the mounting base 351 and the mounting rod 33. The return spring 352 is used to support the mounting base 351, thereby preventing the slide rod 341 fixed on the mounting base 351 from sliding downward under the action of gravity, and thus sliding on the filter belt surface on the filter belt mechanism 2. A roller 353 is rotatably mounted on the mounting base 351. Multiple brackets 354 are fixed on the frame 1, and drive seats 35 that are tactilely connected to the rollers 353 are fixed on the multiple brackets 354. 5. The bottom of the drive base 355 is provided with a guide slope a for driving the roller 353 to move towards the surface of the filter belt mechanism 2. The bottom of the drive base 355 is also provided with a horizontal surface b that smoothly transitions with the guide slope a. When the pressure component 34 passes the guide slope a, the roller 353 slides on the surface of the guide slope a, thereby causing the pressure component 34 to move downward and press against the sludge on the surface of the filter belt mechanism 2, thereby accelerating the separation efficiency of water in the sludge. When the roller 353 rolls to the horizontal surface b, the pressure component 34 maintains the pressing state on the sludge, so that the water in the sludge can have sufficient time to separate from the sludge, thereby accelerating the filtration of water in the sludge.

[0038] As a preferred technical solution in this embodiment, the cleaning component 36 includes a sliding plate 361 vertically slidably disposed within the pressure block 342. Multiple cleaning plates 362 are fixedly attached to the bottom of the sliding plate 361, sliding through the bottom surface of the pressure block 342. A limiting rod 363 is fixedly attached to the top of the sliding plate 361, sliding through the top of the pressure block 342. A cleaning spring 364 is provided between the top of the sliding plate 361 and the top wall of the pressure block 342. When the pressure component 34 comes into contact with the sludge under the drive of the conveyor chain component 31, the multiple cleaning plates 362 slide into the pressure block 342 and ultimately, under the restriction of the limiting rod 363, contact the pressure block 342. 42 The surface remains flush, which allows for the compression of the sludge to accelerate the separation of water from the sludge. When the pressure component 34 is driven by the conveyor chain component 31 to detach from the sludge, mud lumps with low water content may stick to the bottom surface of the cleaning plate 362 and the pressure block 342. At this time, multiple cleaning plates 362 are pushed outward under the action of the cleaning spring 364, which causes the bottom surface of the cleaning plate 362 and the pressure block 342 to be misaligned, so that the mud lumps are detached from the bottom surface of the cleaning plate 362 and the pressure block 342, preventing sludge from continuously adhering to the bottom surface of the pressure block 342 and affecting the subsequent compression effect on the sludge.

[0039] Example 2

[0040] Figure 5 In one embodiment of the present invention, by further adjusting the pressure of the pressure block 342 on the surface of the filter belt mechanism 2, the filter belt mechanism 2 is prevented from being affected by too much or too little sludge on its surface.

[0041] Compared with Example 1, Example 2 is further optimized in that: an adjusting component 37 is provided between the slide rod 341 and the pressure block 342 to adjust the pressure of the pressure block 342 on the surface of the filter belt mechanism 2. When there is too much or too little silt on the surface of the filter belt mechanism 2, the distance between the pressure component 34 and the surface of the filter belt mechanism 2 changes accordingly with the amount of silt when it moves down to press the silt. This avoids the pressure component 34 being unable to effectively press the silt to achieve water separation when there is too little silt, and also avoids the pressure component 34 being damaged due to excessive silt resistance when the silt is too thick. The adjusting component 37 includes a connecting rod 371 fixed to the bottom of the slide rod 341, a limit block 372 fixed to the top of the connecting rod 371, and a slide cylinder 373 fixed to the pressure block 342 slidably connected to the bottom of the connecting rod 371. An adjusting block 374 is threaded onto the connecting rod 371. A limiting block 372 is used to prevent the threads on the connecting rod 371 from getting stuck in the mounting rod 33. At the same time, it cooperates with the return spring 352 to limit the position of the pressure component 34 during transmission. A pressure spring 375 is provided between the adjusting block 374 and the slide cylinder 373. When the pressure block 342 presses the sludge, the connecting rod 371 and the slide cylinder 373 slide relative to each other. Thus, the pressure spring 375 causes the pressure block 342 to press the sludge with a certain pressure, which accelerates the filtration of water. At this time, when the sludge thickness is different, the relative sliding distance between the connecting rod 371 and the slide cylinder 373 changes accordingly, but the pressure on the sludge can still be maintained. This avoids excessive pressure in the connecting rod 371 and the slide rod 341 when the sludge thickness is large, which could cause damage to the parts and improve the stability of the device.

[0042] Example 3

[0043] Figure 8 In one embodiment of the present invention, the cleaning component 36 is further optimized to further clean the fine mud lumps on the surface of the cleaning plate 362 and the pressing block 342.

[0044] Compared with Example 1, Example 3 is further optimized in that: the drive assembly 35 is also provided with a shaking assembly 38 that works with the cleaning assembly 36 to drive the pressure assembly 34 to shake. The shaking assembly 38 includes a mounting surface c that is inclined downward at the end of the drive seat 355 away from the guide slope a. Multiple top plates 381 are fixed on the mounting surface c in a horizontal direction. Rollers 353 are rolled on the multiple top plates 381. When the pressure assembly 34 begins to separate from the sludge, on the one hand, the cleaning assembly 36 reduces the probability of mud lumps adhering to the bottom of the pressure block 342. At the same time, the rollers 353 roll on the multiple top plates 381, so that bumps will occur during the rolling of the rollers 353, thereby causing the pressure block 342 to vibrate. This further drives the mud lumps to fall off the pressure block 342 and the cleaning plate 362, thereby preventing the mud lumps from accumulating on the pressure block 342 and the cleaning plate 362 and affecting the filtration of water in the sludge.
