Description

Technical Field

[0001] This utility model relates to a mechanized cloth laying device, specifically a cloth laying device used in a sludge dewatering machine. Background Technology

[0002] Sludge dewatering machines, also known as sludge filter presses, are used for drying and dewatering sludge. Their working principle involves using various physical principles to separate water from the sludge, thereby reducing its moisture content and enabling the sludge to be transported, processed, and reused.

[0003] Direct pressure filter presses are one of the commonly used sludge dewatering devices. For example, Chinese utility model patent CN216259301U discloses a direct pressure filter press, which includes a sludge-coating mechanism, a primary pressure mechanism, a main pressure mechanism, and a sludge unloading mechanism. Compared with other traditional dewatering machines, this structure is simpler to operate, has a higher degree of automation, and can reduce manpower input.

[0004] However, existing sludge dewatering machines still require at least three workers to lay the filter cloth during startup, filter cloth cleaning, and restarting. Specifically, for example... Figure 1 As shown, a liftable platform 2 is provided in the sludge-packing area to support the stacked sludge bags. A sludge-laying device 5 is located above the sludge-packing area, and a filter cloth stacking device 3 surrounds the area. A filter cloth transfer trolley 4 is also located beside the sludge-packing area. After the filter cloth stacking device 3 finishes wrapping the previous sludge bag, the platform 2 descends a certain distance, and the packaged sludge bag follows. At this point, the top of the uppermost sludge bag is aligned with the folding flap of the unfolded filter cloth stacking device 3. Then, the filter cloth transfer trolley 4 moves the filter cloth to the side of the sludge-packing area, where several workers work together to lay the filter cloth on top of the previous sludge bag and the folding flap. The sludge-laying device 5 then applies the sludge. After the sludge is laid, the filter cloth stacking device 3 activates, completing the sludge wrapping through the folding flap. Then, the platform 2 descends a certain distance, awaiting the next layer of cloth application. Therefore, it is evident that existing sludge dewatering machines require manual cloth application, resulting in high labor intensity and low efficiency. Utility Model Content

[0029] The technical scheme of the utility model will be described in detail below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Embodiment one

[0030] As Figure 2 And 3 A kind of sludge dewatering machine cloth paving device, including installation on the rack 1 of sludge dewatering machine, respectively located in mud area left and right two groups of lifting device, the top of each group of lifting device is provided with longitudinal moving device, longitudinal moving device is installed with electromagnet.

[0031] In the embodiment, the lifting device includes chassis 8 and lifting support 6 located above the chassis 8, and also includes lifting cylinder 7 connected between the chassis 8 and connecting frame. The chassis 8 is installed on the rack 1, and it is slidably connected with the lifting support 6: asFigure 4 The front and rear ends of the lifting frame 6 are respectively provided with vertical posts, and pulleys 12 are installed on the posts. The front and rear ends of the base frame 8 are respectively provided with vertical guide rails 13, and the pulleys 12 on the same side are matched with the guide rails 13. When the lifting cylinder 7 is elongated, the lifting frame 6 is driven to rise, and when the lifting cylinder 7 is contracted, the lifting frame 6 is lowered.

[0032] As an optional embodiment, the lifting frame 6 can also be driven to lift by a screw nut mechanism, and at this time, a vertical screw rod is driven to rotate by a motor, and a nut matched with the screw rod is installed on the lifting frame 6.

[0033] The longitudinal moving device is installed on the lifting frame 6. In the embodiment, as shown in Figure 2 and 3 The longitudinal moving device includes a driving sprocket and a driven sprocket respectively installed on the front and rear ends of the lifting device, and a chain 9 connected between the driving sprocket and the driven sprocket. The driving sprocket is driven by a driving motor, which can be provided with one driving motor on each side, and the driving motor is in transmission connection with the driving sprocket through a speed reducer; or as shown in Figure 3 , the two driving sprockets are fixedly connected together through a transmission shaft 10, and then a driving motor is installed on the mounting plate 11 of the lifting frame 6 on one side, which drives the driving sprocket on this side to rotate, and the driving sprocket drives the driving sprocket on the other side to rotate through the transmission shaft 10, so as to realize the synchronous movement of the two chains 9.

[0034] In the embodiment, as shown in Figure 5 , the electromagnet is a cylindrical electromagnet 14, which is installed at the rotating connection position of adjacent chain plates in the chain 9 instead of a chain pin. It should be noted that all chain pins do not need to be replaced by cylindrical electromagnets 14, but only one or several need to be replaced according to the need.

[0035] The filter cloth laying device of the sludge dewatering machine further includes iron blocks fixed at the left and right side edges of the filter cloth. Only one cylindrical electromagnet 14 can be installed on each chain 9, which is used to adsorb the iron block at the front end of the filter cloth; or multiple cylindrical electromagnets 14 can be installed to continuously adsorb the filter cloth, so that the filter cloth is more closely and flatly matched with the chain 9 during movement. When multiple cylindrical electromagnets 14 are provided, the spacing between adjacent electromagnets on the chain 9 should match the spacing between adjacent iron blocks on the filter cloth. The cylindrical electromagnet 14 is connected with an external power source through a wire.

[0036] The lifting support 6 is also provided with a roller slide rail 15, the top of the roller slide rail 15 is provided with a freely rotating roller, the roller is used to contact the upper chain 9. Because the chain 9 is long, after the filter cloth is adsorbed, the middle part will sink under the action of gravity, at this time, the chain 9 can contact the roller, avoiding friction with the lifting support 6, thereby reducing wear and tear and prolonging the service life.

[0037] As Figure 2 and 3 When the last mud bag is wrapped and the platform 2 is lowered, the transfer trolley 4 moves the next filter cloth to the side, and the left and right edges of the front end of the filter cloth are respectively fixed with an iron block. Then the lifting cylinder 7 is extended, the lifting support 6 is lifted, the chain 9 starts to rotate under the drive of the driving motor, and the electromagnet is powered on. When the first cylindrical electromagnet 14 on both sides approaches the iron block, the two are attracted, and then the entire filter cloth is moved forward. If multiple electromagnets are arranged on the chain 9, the attraction will occur continuously during the movement, thereby ensuring that the filter cloth is well attached to the chain 9. When the filter cloth moves to the limit position, the driving motor stops moving, the lifting cylinder 7 is retracted to lower the lifting support 6, and the electromagnet is powered off. The entire filter cloth falls on the folding flap and the previous mud bag, and the cloth laying is completed. At this time, the chain 9 moves in the opposite direction, so that the electromagnet returns to the original position (the chain 9 cannot always move in one direction, otherwise the wire will be wound). After the next mud bag is wrapped, the lifting support 6 is lifted again for cloth laying operation. Example Two

[0038] The difference between this embodiment and example one is that a connecting plate is installed on the chain through a clamp. Each chain is only provided with one electromagnet, which is installed on the connecting plate.

[0039] The advantage of this structure is that the shape of the electromagnet is not limited, which is convenient for selection, and the installation of the electromagnet is more stable and will not be loose or damaged due to repeated contact with the chain wheel. The disadvantage is that the connecting plate cannot pass through the chain wheels at both ends, so only one electromagnet can be configured. Example Three

[0040] The difference between this embodiment and example one is that the longitudinal moving device is a screw slide rail walking mechanism: a screw is installed on each lifting support on the two sides through a bearing seat, and the screw rotates under the drive of a motor. A nut is installed on the screw, a connecting plate is installed on the nut, the connecting plate and the lifting support are connected through a slide rail, and an electromagnet is installed on the connecting plate.

[0041] The advantage of this structure is that the noise is small, and the disadvantage is that a control system is needed to realize synchronous movement of the two sides, and only one electromagnet can be installed on each side. Example Four

[0042] The embodiment is different from the embodiment one in that the longitudinal moving device is a gear and rack walking mechanism; a rack is installed on the top of the lifting support and a sliding rail, a sliding block is installed on the sliding rail, a moving plate is installed on the top of the sliding block, a motor is installed on the moving plate, a gear is connected with the output shaft of the motor, and the gear is engaged with the rack.

[0043] The structure can also drive the electromagnet to move linearly and complete the cloth laying operation, but has problems of high cost, need for synchronous control, and usually only one electromagnet can be installed.

[0044] It should be noted that, for those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model. The scope of the utility model is defined by the claims rather than the above description.
