Abstract
Description
Technical Field
[0001] This utility model relates to the field of unloader technology, and in particular to an adjustable unloader. Background Technology
[0002] A belt filter press is a solid-liquid separation device primarily used for sludge treatment and dewatering. It separates sludge into filter cakes and clean water. The filter cakes can be directly transported, landfilled, or used for other industrial applications, while the clean water can be recycled. Belt filter presses are characterized by large processing capacity, high dewatering efficiency, high degree of automation, and long service life, making them ideal equipment for environmental remediation and resource recovery.
[0003] Chinese patent CN101884857B discloses a vacuum belt filter press, including a frame, a drive unit, a feeder, a filter belt, rollers, a filter belt tensioning device, a filter belt cleaning device, and a discharger. The drive unit is mounted on the frame and drives the rollers to rotate and the upper and lower filter belts to operate. The rollers include guide rollers, support rollers, constant pressure rollers, and vacuum rollers. The key feature is that the constant pressure rollers and / or vacuum rollers are installed individually or in pairs to filter wet materials. The vacuum rollers have at least two or more vacuum chambers in the same vacuum chamber, corresponding to the thickness distribution of the filter cake. The vacuum chambers are distributed from high to low, from the middle to both sides. During operation, the high and low vacuum chambers form different vacuum levels, ensuring that all parts of the material can be drawn through by the vacuum negative pressure. The water squeezed out of the material surface and adhering to the filter belt under the mechanical squeezing action of the rollers is quickly drawn into the vacuum rollers, thereby achieving a significant reduction in the moisture content of the filtered material and obtaining higher overall processing efficiency.
[0004] However, the position between the scraper and the filter cloth roller in the unloader of this technical solution is not adjustable. After long-term use, the filter cloth will loosen. At this time, the gap between the scraper and the filter cloth increases, and the material on the filter cloth cannot be completely removed, leaving residue and resulting in poor cleaning effect.

[0029] Example
[0030] like Figure 1 and Figure 2 As shown, this embodiment provides an adjustable unloader, including: a filter cloth roller 1 movably mounted on the filter press frame via a mounting base 2; an unloading component 4 abutting against the surface of the filter cloth roller 1; a lifting component 5 for adjusting the clamping force between the unloading component 4 and the filter cloth roller 1; and a receiving component 6 disposed on the mounting base 2 for receiving and restricting the movement of the unloading component 4. The lifting component 5, in conjunction with the receiving component 6, allows the unloading component 4 to rotate on the rotating shaft 3, thereby adjusting the angle of the unloading component 4. This allows the unloading component 4 to move closer to or further away from the filter cloth roller 1, thus maximizing the unloading of material from the filter cloth roller 1. The entire process is simple to operate, requires no manual labor, has a high degree of automation, and is convenient to use.
[0031] The mounting base 2 is also provided with a rotating shaft 3, which is located below the filter cloth roller 1. Both ends of the rotating shaft 3 are respectively mounted on the mounting base 2 by setting a shaft seat 31, so as to ensure that the rotating shaft 3 can move on the mounting base 2 with the shaft seat 31.
[0032] Meanwhile, the unloading assembly 4 includes a scraper 41 and connecting plates 42 respectively disposed at both ends of the scraper 41. The connecting plates 42 are mounted on the rotating shaft 3 and drive the scraper 41 to move synchronously with the rotation of the rotating shaft 3 to adjust the distance between the scraper 41 and the filter cloth roller 1. The scraper 41 is located at an angle below the outer side of the filter cloth roller 1, thereby automatically adjusting the contact pressure between the scraper 41 and the filter cloth roller 1 in real time to ensure the cleaning effect of the filter cloth. Several sets of the hoisting assemblies 5 are provided on the outer side of the scraper 41 to ensure the stability and firmness of the scraper 41 and avoid shaking.
[0033] In this embodiment, a counterweight 43 is movably disposed on the connecting plate 42, which is located on the inner side of the scraper 41 at an angle below. The counterweight 43 can be used to increase the stability of the unloading assembly 4 and prevent the equipment from tipping over or moving during operation.
[0034] In this embodiment, the connecting plate 42 is provided with an adjustment groove 421 that is perpendicular to the tangential direction of the scraper 41. The counterweight 43 is fixedly mounted on the adjustment groove 421 by locking members 422 provided at both ends, so that the counterweight 43 can move along the adjustment groove 421 to change the position of the counterweight 43 to adapt to the change in position between the scraper 41 and the filter cloth roller 1.
[0035] In this embodiment, the tangential direction of the scraper 41 relative to the filter cloth roller 1 is perpendicular to the adjustment direction of the counterweight 43. The perpendicular setting can help maintain the contact pressure and angle between the scraper 41 and the filter cloth roller 1, thereby improving the filtration efficiency.
[0036] In this embodiment, when the tension of the filter cloth needs to be adjusted by adjusting the position of the transverse adjustment roller, the position of the scraper 41 can be adjusted simultaneously to ensure the contact pressure between the scraper 41 and the filter cloth roller 1.
[0037] In this embodiment, the hoisting assembly 5 includes: a fixed base 51 fixedly connected to the outside of the scraper 41 and an elastic element 52 disposed between the fixed base 51 and the top plate 21 of the mounting base 2. The top plate 21 is mounted on one side of the mounting base 2 and is used to install the elastic element 52. The elastic element 52 is vertically arranged and is preferably a spring because the spring can extend and retract freely. That is, the scraper 41 automatically adjusts according to the different thicknesses of the material on the filter cloth roller 1 to scrape the material on the filter cloth roller 1 cleanly, so as to ensure the cleanliness of the filter cloth roller 1.
[0038] In this embodiment, the connecting plate 42 is trapezoidal, and its lower end can be arranged to contact the receiving component 6 to restrict the rotation of the connecting plate 42, so that the unloader has a compact structure and is sufficiently stable during operation.
[0039] In this embodiment, the mounting base 2 is provided with an auxiliary bracket 22, and the receiving component 6 includes: a support base 61 slidably connected to the auxiliary bracket 22 and a support rod 62 that can be raised and lowered and adjusted on the support base 61. The support rod 62 abuts against the lower end of the connecting plate 42, preferably the support rod 62 abuts against the bottom of the connecting plate 42. When it is necessary to adjust the horizontal position of the scraper 41, it is only necessary to move the support base 61. The operation is simple and convenient.
[0040] Of course, the receiving component 6 can be adjusted laterally on the auxiliary bracket 22. The auxiliary bracket 22 is provided with a waist-shaped groove 221. The support seat 61 slides in the waist-shaped groove 221 and is fixed by a number of fasteners 222. The waist-shaped groove 221 limits the range of movement of the support seat 61 in the horizontal direction to correspond to different materials on the filter cloth roller 1. Because different materials have different thicknesses, the fasteners 222 ensure the accuracy of the positioning of the support seat 61. It is simple to operate and easy to disassemble and assemble.
[0041] In addition, the support rod 62 and the support base 61 are connected by a thread, so that the height of the support rod 62 is adjustable, thereby ensuring that the distance between the scraper 41 and the filter cloth roller 1 is adjustable to adapt to the change in the position of the scraper 41, so that the scraper 41 can maintain stability in a timely manner.
[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
