Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment, and particularly relates to a lower beam fixing device of a sludge dewatering machine. Background Art

[0002] In a sludge treatment system, a sludge dewatering machine, also known as a heavy press, is a device used to dewater water-containing sludge to reduce the volume and weight of the sludge, facilitating subsequent treatment and disposal. The applicant's prior invention patent CN114292004B discloses a sludge treatment system and a sludge treatment method, and particularly relates to a heavy press. The oil cylinder of the heavy press is arranged on the upper beam, and the upper beam is fixed to the lower beam through columns, with the lower beam supporting the upper beam, and the lower beam is fixed to the ground by a bottom plate. The lower beam supports the upper beam and the oil cylinder, etc. When the heavy press compresses the material cloth covering the sludge, there is a possibility of movement of the upper beam and the lower beam caused by lateral force. Therefore, the fixation with the bottom plate should not rely solely on the gravity of the heavy machine, and the fixation method between the lower beam and the bottom plate needs to be strengthened.

[0003] The most empirical way to fix the lower beam and the bottom plate is to use bolts to tighten them laterally. However, it has been found in engineering that when the heavy press compresses the cloth covering the sludge, it may also cause a slight longitudinal offset of the lower beam. Therefore, to improve the support stability of the lower beam, the lower beam and the bottom plate should be stably fixed longitudinally. Content of the Utility Model

[0039] The embodiments of the present application will be described in detail below with reference to the accompanying drawings. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0040] In the first embodiment, as Figures 1-3 shown, a lower beam fixing device of a sludge dewatering machine includes a stop block 100, a lower beam 200, a base plate 300, and a positioning block 400.

[0041] In a specific example, two side surfaces of the lower beam 200 include a first side surface 210 and a second side surface 220. The bottom plate 300 on the side where the first side surface 210 is located is a first side bottom plate 310, and the bottom plate 300 on the side where the second side surface 220 is located is a second side bottom plate 320. The stoppers 100 are oppositely arranged transversely at the lower parts of the two side surfaces of the lower beam 200. Preferably, the bottom surface of the stopper 100 abuts against the upper surface of the corresponding side bottom plate 300, and this abutment is formed by relying on the gravity of the lower beam 200. The bottom plate 300 supports the lower beam 200.

[0042] In a specific example, the stopper 100 includes a first stopper 110, a second stopper 120, a third stopper 130, and a fourth stopper 140. Among them, the first stopper 110 and the second stopper 120 are arranged at the lower part of the first side surface 210 of the lower beam 200, and the third stopper 130 and the fourth stopper 140 are arranged at the lower part of the second side surface 220 of the lower beam 200. The positioning block 400 includes a first positioning block 410, a second positioning block 420, a third positioning block 430, and a fourth positioning block 440. Among them, the first positioning block 410 and the second positioning block 420 are arranged on the first side bottom plate 310, and the fourth positioning block 440 and the third positioning block 430 are arranged on the second side bottom plate 320. The first stopper 110 and the second stopper 120 are limited between the first positioning block 410 and the second positioning block 420, and the third stopper 130 and the fourth stopper 140 are limited between the third positioning block 430 and the fourth positioning block 440.

[0043] In a specific example, transversely, the first stopper 110 and the third stopper 130 are oppositely arranged, and the second stopper 120 and the fourth stopper 140 are oppositely arranged. The first positioning block 410 and the third positioning block 430 are oppositely arranged, and the second positioning block 420 and the fourth positioning block 440 are oppositely arranged. More specifically, a certain distance is provided between the first stopper 110 and the second stopper 120 longitudinally, and a certain distance is provided between the third stopper 130 and the fourth stopper 140 longitudinally.

[0044] According to the relative spatial arrangement formed above, more specifically, longitudinally, the first positioning block 410 is arranged on the first side of the first stop block 110. Among the two adjacent side surfaces of the first positioning block 410, the second side surface 840 in the longitudinal direction abuts against the first side surface 830 of the first stop block 110 in the longitudinal direction, and the second side surface 820 in the transverse direction among the two side surfaces abuts against the first side surface 210 of the lower beam 200 in the transverse direction. Longitudinally, the second positioning block 420 is arranged on the second side of the second stop block 120. Among the two adjacent side surfaces of the second positioning block 420, the first side surface 830 in the longitudinal direction abuts against the second side surface 840 of the second stop block 120 in the longitudinal direction, and the second side surface 820 in the transverse direction among the two side surfaces abuts against the first side surface 210 of the lower beam 200 in the transverse direction. Longitudinally, the third positioning block 430 is arranged on the first side of the third stop block 130. Among the two adjacent side surfaces of the third positioning block 430, the second side surface 840 in the longitudinal direction abuts against the first side surface 830 of the third stop block 130 in the longitudinal direction, and the first side surface 810 in the transverse direction among the two side surfaces abuts against the second side surface 220 of the lower beam 200 in the transverse direction. Longitudinally, the fourth positioning block 440 is arranged on the second side of the fourth stop block 140. Among the two adjacent side surfaces of the fourth positioning block 440, the first side surface 830 in the longitudinal direction abuts against the second side surface 840 of the fourth stop block 140 in the longitudinal direction, and the first side surface 810 in the transverse direction among the two side surfaces abuts against the second side surface 220 of the lower beam 200 in the transverse direction. As described above, one side surface of the positioning block 400 abuts against the stop block 100, and the other side surface abuts against one side surface of the lower beam 200. The lower beam 200 is limited in the longitudinal direction by the abutting manner of the stop block 100, and the lower beam 200 is limited in the transverse direction by the manner of abutting against the side surface of the lower beam 200, so as to realize the lateral and longitudinal offset limitation of the lower beam 200. The above two positioning blocks 400 are longitudinally arranged on both sides of the stop block 100 to limit the stop block 100 longitudinally. Among them, one surface of the two adjacent surfaces on the positioning block 400 is arranged to abut and cooperate with the stop block 100 of the lower beam 200, which is equivalent to realizing the positioning and limitation of the lower beam 200 by the positioning block 400 through the stop block 100 of the lower beam 200 longitudinally, and hindering the longitudinal movement of the lower beam 200. Moreover, the positioning blocks 400 are also oppositely arranged on both sides of the lower beam 200, and the other surfaces of the positioning blocks 400 on both sides of the lower beam 200 abut against the two side surfaces of the lower beam 200 relatively, which is equivalent to realizing the positioning and limitation of the lower beam 200 by the positioning blocks 400 in the transverse direction. The arrangement of the positioning blocks 400 can realize the positioning and limitation of the lower beam 200 in two directions at the same time, and hinder the lateral and longitudinal offset of the lower beam 200 at the same time.

[0045] In a specific example, the lower beam fixing device of the sludge dehydrator further includes an adjusting shim 700, and the adjusting shim 700 is filled in the gap between the positioning block 400 and the stop block 100 and / or between the positioning block 400 and the lower beam 200 when there is a gap therebetween. For the sludge treatment systems of different scales, there are certain differences in the sizes of the lower beam 200, the bottom plate 300 and the stop block 100. To standardize the size of the positioning block 400 for convenient manufacturing, the same-sized positioning block 400 may have a gap with the stop block 100 or the lower beam 200 due to the size differences of the systems and cannot be pressed against. Therefore, in this application, the same-sized positioning block 400 is adapted to different sludge treatment systems, and the gap is filled by adapting the adjusting shim 700 to achieve pressing, which can not only unify the size of the positioning block 400 for convenient manufacturing but also realize the pressing and limiting function of the positioning block 400.

[0046] A through first bolt hole is provided on the positioning block 400, and a second bolt hole opposite to the first bolt hole on the positioning block 400 is provided on the bottom plate 300. The positioning block 400 is fixed on the bottom plate 300 by bolts cooperating with the first bolt hole and the second bolt hole. The above describes the fixing method between the positioning block 400 and the bottom plate 300.

[0047] In a specific example, the lower beam fixing device of the sludge dehydrator further includes fastening bolts 500 and bolt hole columns 600. The bolt openings of the bolt hole columns 600 are arranged in the first direction. The fastening bolts 500 include a first fastening bolt 510, a second fastening bolt 520, a third fastening bolt 530, and a fourth fastening bolt 540. The bolt hole columns 600 include a first bolt hole column 610, a second bolt hole column 620, a third bolt hole column 630, and a fourth bolt hole column 640. The first bolt hole column 610 and the second bolt hole column 620 are arranged on the first side bottom plate 310 at a certain distance apart in the second direction. The third bolt hole column 630 and the fourth bolt hole column 640 are arranged on the second side bottom plate 320 at a certain distance apart in the second direction. Longitudinally, the first bolt hole column 610 is arranged on the first side of the first positioning block 410. The first fastening bolt 510 cooperates with the first bolt hole column 610, and the bottom of the first bolt hole column 610 presses against the first lateral side 210 of the lower beam 200 in the transverse direction. Longitudinally, the second bolt hole column 620 is arranged on the second side of the second positioning block 420. The second fastening bolt 520 cooperates with the second bolt hole column 620, and the bottom of the second bolt hole column 620 presses against the first lateral side 210 of the lower beam 200 in the transverse direction.

The fourth fastening bolt 540 cooperates with the fourth bolt hole column 640, and the bottom of the fourth bolt hole column 640 presses against the second lateral side 220 of the lower beam 200 in the transverse direction. The above bolts are further limited in the transverse direction to supplement the offset limit of the lower beam 200 in the transverse direction. The first bolt hole column 610 and the third bolt hole column 630 are arranged opposite to each other. The second bolt hole column 620 and the fourth bolt hole column 640 are arranged opposite to each other. The oppositely arranged bolt hole columns 600 can balance the position of the pressing action.
