[0023] The present embodiment discloses a belt support for supporting the upper and lower parts of the rubber filter belt (referred to as belt) of a rubber belt type vacuum filter.

[0024] As Figure 1As shown, the rubber belt type vacuum filter mainly comprises a rack 1, a rubber filter belt 2, a driven roller 3, a feeding hopper 4, a belt support 5, an isolator 6, a vacuum box 7, a liquid collecting main pipe 8, a driving speed reducer 9, a driving roller 10, a filter cloth 11, a plurality of redirection rollers 12, a discharging scraper 13, a cleaning device 14, a deviation rectifying device 15, a tensioning device 16 and the like.

The belt support 5 is arranged along the length direction of the rack 1 and is arranged in parallel with the vacuum box 7. The two ends of the rubber filter belt 2 are respectively wound around the driving roller 10 and the driven roller 3, the upper middle part is arranged on the vacuum box 7 and the belt support 5 and slides on the vacuum box 7 and the belt support 5, and the lower middle part is also carried by the belt support 5. The structure of the rubber belt type vacuum filter belongs to the prior art, and will not be described here.

[0025] Referring to Figures 2-5 The belt support comprises a support table 51 fixedly connected to the rack, a sliding belt assembly 52 arranged on the upper end surface of the support table 51, and a ring-shaped belt 53 arranged around the support table 51 and the sliding belt assembly 52, and the rubber belt is attached to the ring-shaped belt 53.

[0026] Specifically, the support table 51 has a predetermined length to have enough space to match the rubber belt. In order to simplify the installation structure and reduce the cost, the support table 51 can adopt a square tube structure in the embodiment. The sliding belt assembly 52 is arranged on the upper end surface of the support table 51, and the two ends of the sliding belt assembly 52 are respectively connected to the two sides of the support table 51.

[0027] More specifically, in combination with Figure 5 The sliding belt assembly 52 comprises a plurality of sliding belt bases 521, the length of the sliding belt base 521 matches the width of the support table 51, the first end and the second end of the plurality of sliding belt bases 521 are respectively provided with connecting holes 523, and the first end and the second end are hingedly connected by a connecting shaft to form a belt-shaped structure and cover the upper end surface of the support table 51. Further, at least one mounting groove for mounting a ball 522 is arranged along the length direction of the sliding belt base 521, the ball 522 is rotatably connected to the mounting groove by a mounting shaft 524, and the axis direction of the mounting shaft 524 is the length direction of the sliding belt base 521. In the embodiment, the height of the ball 522 is higher than the upper surface of the sliding belt base 521, and when the sliding belt base 521 carries the ring-shaped belt 53, the ball 522 rotatably connected with the sliding belt base 521 directly contacts with the ring-shaped belt 53, so as to realize the rolling friction between the ring-shaped belt 53 and the ball 522.

[0028] Preferably, the rolling ball 522 can adopt a self-lubricating material to reduce maintenance costs. In the sliding belt assembly 52, a plurality of sliding belt bases 521 are detachably connected, and the overall length of the sliding belt assembly 52 can be adjusted by adjusting the number of sliding belt bases 521, so that the applicability is better. The detachable hinged manner is a prior art, and the structure thereof will not be described here.

[0029] As shown in Figure 6 , both ends of the support table 51 are fixedly connected with mounting plates 511, and the sliding belt bases 521 on both sides of the sliding belt assembly 52 are hinged to the flange structures fixedly arranged on the mounting plates 511.

[0030] In the embodiment, the sliding belt base 521 and the rolling ball 522 are both made of plastic material, such as PP or POM material, which has better wear resistance, acid and alkali resistance, and corrosion resistance.

[0031] As shown in Figure 2 , corresponding to the positions of the two ends of the support table 51, there are tension pulleys 54 for connecting the annular tow belt 53. Specifically, the end sides of the support table 51 are fixedly connected with fixed plates 55, and the tension pulleys 54 are rotatably connected between the two fixed plates 55. The aforementioned annular tow belt 53 is arranged around the two tension pulleys 54 and is tensioned by the two tension pulleys 54 to prevent it from moving. The annular tow belt 53 is arranged around the whole support table 51 and the sliding belt assembly 52, the upper end portion of the annular tow belt 53 is attached to the rolling ball 522, and the lower end portion is arranged at the bottom end of the support base. In the embodiment, the annular tow belt 53 is made of acid and alkali resistant, corrosion resistant and low cost rubber products.

[0032] In actual application, the adhesive tape is closely attached to the annular tow belt 53, that is, the bottom surface of the upper end adhesive tape is attached to the top surface of the annular tow belt 53, and the top surface of the lower end adhesive tape is attached to the bottom surface of the annular tow belt 53. The support table 51 is supported by the sliding belt assembly 52 and the annular tow belt 53. When the device is running, under the drive of the driving roller, the adhesive tape runs and drives the annular tow belt 53 to move through friction. The rolling ball 522 on the sliding belt base 521 makes the movement form between the annular tow belt 53 and the sliding belt assembly 52 be rolling friction, thereby reducing the running resistance of the annular tow belt 53. In the embodiment, the spacing of the annular tow belt 53 not only reduces the wear of the adhesive tape, but also plays a role in flattening the adhesive tape.

[0033] To prevent the sliding belt assembly 52 or the annular tow belt 53 from moving or displacing, the two side ends of the support table 51 are also connected with a plurality of blocking blocks 56 for limiting and blocking the sliding belt assembly 52 and the annular tow belt 53.

[0034] When the device is in operation, the adhesive tape is dragged to run on the vacuum box 7 and the adhesive tape support 5 by the rotating driving roller 10 through friction, the adhesive tape drags the annular drag tape 53 to move through friction, and the annular drag tape 53 rolls and rubs on the sliding tape assembly 52. When the vacuum is turned on, the adhesive tape drags the filter cloth 11 to move together through vacuum adsorption, the feeding hopper 4 arranges the material on the filter cloth 11 at one end of the vacuum adsorption area, under the action of the vacuum adsorption force and gravity, the liquid in the material penetrates through the filter cloth 11, is collected into the vacuum box 7 through the liquid discharge hole from the liquid discharge groove on the adhesive tape and is discharged; and the solid particles are intercepted by the filter cloth 11 to form filter cake, with the running of the adhesive tape on the adhesive tape support 5, the material is processed in turn through filtering, washing, drying and other processes, and finally is unloaded at the scraper to complete the process requirements of dewatering and impurity removal or useful recovery.
