Description

Technical Field

[0001] The invention belongs to the field of solid-liquid separation devices, and in particular, relates to filter cloth laying and unloading and winding equipment and material laying and material unloading systems. Background Art

[0002] There are many methods for solid-liquid separation, including pressing, extrusion, centrifugation, etc., and the corresponding solid-liquid separation equipment is also diverse. Currently, the more widely used equipment are belt dehydrators and plate and frame filter presses. However, after the water-containing material is dehydrated by pressure filtration, the dehydrated material is stuck to the filter cloth and needs to be processed. Since the filter cloth is long, there are many movements during the unloading, cleaning and winding process, resulting in a large equipment volume, a large space occupation, poor cleaning effect on the filter cloth and low unloading efficiency. In addition, when spreading the material on the filter cloth, it is necessary to ensure the uniformity of the material so that the equipment can apply force evenly and stably during extrusion dehydration, while ensuring efficient spreading, but the existing technology is relatively lacking.

[0003] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0041] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] The filter cloth unloading and unloading and winding equipment is used for unloading and unloading the filter cloth for water-containing material pressure filtration, and comprises a unloading functional unit, a filter cloth arranging functional unit and a filter cloth unloading and winding functional unit which are connected in sequence.

[0044] The unloading functional unit is arranged at the upper part of the whole equipment.

[0045] The unloading functional unit includes a driving guide roller 5-3 and a material conveyor 5-4 tangent to the driving guide roller 5-3, and also includes an expansion plate 5-1 and a smooth conveying plate 5-2. According to the traveling direction of the filter cloth 3-7 when the filter cloth is rolled up, the expansion plate 5-1, the smooth conveying plate 5-2 and the driving guide roller 5-3 are arranged in sequence.

[0046] The expansion plate 5-1 is provided with raised patterns, which are in the shape of an inverted figure eight according to the direction of the filter cloth when the filter cloth is rolled up and unloaded. When the filter cloth 3-7 passes through the expansion plate 5-1, the raised patterns expand the weft width of the cloth under the action of the raised patterns, reducing wrinkles and allowing the material to be spread loosely on the surface of the filter cloth 3-7.

[0047] The filter cloth finishing functional unit is arranged in the middle of the entire equipment, including three free guide rollers arranged in a V shape, namely the first free guide roller 5-5, the second free guide roller 5-7 and the third free guide roller 5-9, and a wrinkle removal roller 5-6 located between the second free guide roller 5-7 at the bottom of the V shape and the first free guide roller 5-5 on one side; and a scrubber 5-8 located between the second free guide roller 5-7 at the bottom of the V shape and the third free guide roller 5-9 on the other side.

[0048] There may be one or more wrinkle removal rollers 5-6, preferably two or more. In the present embodiment, there are two wrinkle removal rollers 5-6.

[0049] The wrinkle removal roller 5-6 in the filter cloth finishing functional unit is provided with a working position and an idle position. The position of the wrinkle removal roller 5-6 is moved by the extension and contraction of the suspension supporting the wrinkle removal roller 5-6, thereby forming the working position and the idle position of the wrinkle removal roller 5-6. The two wrinkle removal rollers are respectively arranged on the front and back sides of the filter cloth. When the filter cloth is rolled and unloaded, Figure 1 As shown, the wrinkle removal roller 5-6 is in the working position, and the two wrinkle removal rollers 5-6 contact the filter cloth 3-7 from the front and back sides respectively, and press the filter cloth 3-7 between the first free guide roller 5-5 and the second free guide roller 5-7 in two opposite directions to tighten the filter cloth 3-7 to remove the wrinkles of the filter cloth; when the filter cloth is placed, as shown in FIG. Figure 2 As shown, the wrinkle removal roller 5-6 retreats to the idle position, and the wrinkle removal roller 5-6 does not contact the filter cloth 3-7. The filter cloth 3-7 is directly transported on the first free guide roller 5-5 and the second free guide roller 5-7 to reduce the transmission resistance.

[0050] The scrubber 5-8 includes multiple groups, each group of scrubbers 5-8 includes a high-pressure spray gun 5-8-1, a rotating brush 5-8-2 and a flushing back plate 5-8-3, the high-pressure spray gun 5-8-1 and the rotating brush 5-8-2 are on the same side of the filter cloth, and are arranged opposite to the flushing back plate 5-8-3, the flushing back plate 5-8-3 is located on the other side of the filter cloth 3-7, and the filter cloth 3-7 passes between the high-pressure spray gun 5-8-1 and the flushing back plate 5-8-3. The multiple high-pressure spray guns 5-8-1 and the rotating brush 5-8-2 in each group of scrubbers 5-8 are arranged at intervals, that is, one rotating brush 5-8-2 is arranged between two high-pressure spray guns 5-8-1, and one high-pressure spray gun 5-8-1 is arranged between two rotating brushes 5-8-2. The flushing back plates 5-8-3 in two adjacent groups of scrubbers 5-8 can be located on both sides of the filter cloth, or on the same side of the filter cloth. In this embodiment, the flushing back plates 5-8-3 in two adjacent groups of scrubbers 5-8 are located on both sides of the filter cloth.

[0051] The filter cloth finishing functional unit also includes a water collecting and draining device 5-10, which is arranged below and to the side of the three free guide rollers and wrinkle removal roller 5-6 and the scrubber 5-8 arranged in a V shape to collect all the rinse water and discharge it from the drain port.

[0052] Since the three free guide rollers are arranged in a V shape, and wrinkle removal rollers 5-6 and scrubbers 5-8 are respectively arranged on the two arms of the V shape, and according to the traveling direction of the filter cloth when the filter cloth 3-7 is rolled up, multiple groups of scrubbers 5-8 are arranged on the rising V-shaped arms formed by the three free guide rollers arranged in the V shape, so that the washing water of the filter cloth by the upper scrubbers 5-8 can flow downward along the filter cloth to wash the filter cloth below, and since the filter cloth cleaned by the upper scrubbers 5-8 has been cleaned by the lower scrubbers 5-8, its dirtiness is more serious. The filter cloth is low, so that the water after the upper scrubber 5-8 washes the filter cloth can flow to the filter cloth below to wash the filter cloth, which not only increases the amount of washing water for the filter cloth below, but also provides cleaner washing water for washing the filter cloth below. Therefore, compared with the horizontal arrangement of the scrubber 5-8 and the filter cloth, the utilization efficiency of the washing water and the degree of cleanliness of the filter cloth can be improved, and the oblique arrangement can utilize the flow formed by the gravity of the washing water and the washed material itself, which is convenient for collecting and discharging the washing water and the washed material. At the same time, the wrinkle removal roller 5-6 is arranged on the other arm of the V-shaped arm, which can effectively utilize the space formed by the V-shaped arm where the scrubber 5-8 is located, and avoid the equipment occupying too much space.

[0053] The filter cloth unwinding and rewinding functional unit includes a positioner 5-11 and a cloth reel 5-13 disposed in the middle and lower part of the filter cloth unwinding and unloading reeling device 5, and the positioner 5-11 is located between the filter cloth finishing functional unit and the cloth reel 5-13. In this embodiment, a fourth free guide roller 5-12 is also disposed between the positioner 5-11 and the cloth reel 5-13.

[0054] The positioner is located outside the rising V-shaped arm formed by the three free guide rollers, and is arranged behind the third free guide roller 5-9. By utilizing the large-span and vertical structure between the third free guide roller 5-9 located above the middle of the equipment and the fourth free guide roller 5-12 located below the equipment, the positioner is located between the third free guide roller 5-9 and the fourth free guide roller 5-12, which can better utilize the sagging of the filter cloth for positioning and improve the positioning effect.

[0055] The filter cloth placing and unloading and winding device 5 has its functional units arranged in sequence from top to bottom, and the overall structure is compact, which reduces space occupation and can fully realize the functions of material unloading, filter cloth arrangement, cleaning and filter cloth winding.

[0056] When the filter cloth placing, unloading and winding device 5 is performing the cloth placing work, the filter cloth 3-7 is rolled up on the cloth winding roller 5-13, and one end of the filter cloth 3-7 is located in the filter cloth roll. The filter cloth on the filter cloth roll is provided to other equipment other than the equipment that needs filter cloth, such as filter cloth laying and folding-spraying coating equipment, through the filter cloth placing, unloading and winding device 5.

[0057] The active guide roller 5-3 and the cloth winding roller 5-13 are driven by the motor to transmit the filter cloth outward, and provide clean and flat filter cloth for other equipment that needs filter cloth, such as filter cloth folding-spray coating equipment, to ensure the high consistency of the overall device process; Figure 2 As shown, when the cloth placing process is executed, the wrinkle removal roller 5-6 is in an idle position, the wrinkle removal roller 5-6 does not contact the filter cloth 3-7, and the filter cloth 3-7 is directly transported on the first free guide roller 5-5 and the second free guide roller 5-7 to reduce the transmission resistance until the filter cloth folding-spray coating equipment is finished and the cloth placing process stops.

[0058] When the cloth unloading process begins, the cloth unloading roller 5-13 and the active guide roller 5-3 in the filter cloth unloading and unloading winding device 5 are driven by the motor to rotate, and the rotation direction is opposite to that in the cloth unloading process, driving the filter cloth 3-7 to move and recover the filter cloth; the material squeezed and dehydrated by other devices outside the equipment is carried on the filter cloth 3-7 and enters the unloading functional unit of the equipment together with the filter cloth 3-7.

[0059] Since the extrusion process causes 3-7 wrinkles on the filter cloth, when the filter cloth is recovered, it passes through the unloading function unit, the filter cloth arranging function unit, and the filter cloth winding and unwinding function unit in sequence to complete unloading, flattening, and winding.

[0060] When in the unloading function unit, the filter cloth 3-7 expands the weft width under the action of the raised lines of the expansion plate 5-1 when passing through the expansion plate 5-1, reducing wrinkles and making the material loosely spread on the surface of the filter cloth; the smaller friction between the smooth conveying plate 5-2 and the filter cloth 3-7 is conducive to the smooth passage of the filter cloth, and also provides tension for the winding of the filter cloth. When the filter cloth 3-7 passes through the active guide roller 5-3, the material on the filter cloth is peeled off by the material conveyor 5-4 and falls into the auger through the inclined surface, and then sent away by the auger to complete the unloading.

[0061] Subsequently, the filter cloth 3-7 after the material is peeled off passes through the filter cloth finishing functional unit. At this time, the wrinkle removal roller 5-6 is in the working position, and the wrinkle removal roller 5-6 rotates to remove wrinkles from the filter cloth 3-7; then the scrubber 5-8 scrubs the filter cloth 3-7.

[0062] Finally, the filter cloth 3-7 enters the filter cloth winding and unwinding functional unit, and the filter cloth is wound on the cloth winding roller 5-13 after passing through the positioner 5-11 and the fourth free guide roller 5-12. The positioner 5-11 corrects the position of the filter cloth to prevent deviation, so that the filter cloth is rolled into a neat cloth roll on the cloth winding roller 5-13.

[0063] The filter cloth unloading and unloading and winding equipment in the present invention is used for unloading and unloading of filter cloth for water-containing material pressure filtration, and includes a unloading function unit, a filter cloth arranging function unit and a filter cloth unwinding and winding function unit connected in sequence. The unloading function unit unloads the material after extrusion and dehydration from the filter cloth, the filter cloth arranging function unit flattens the filter cloth for unloading the material and cleans it, and the filter cloth unwinding and winding function unit winds up the filter cloth and unloads the cloth. By arranging three functional units at the upper, middle and lower parts of the equipment, the functions of unloading the material from the filter cloth, flattening the filter cloth, winding the filter cloth and unloading the cloth are realized. The structure is compact and occupies little space, and the filter cloth cleaning effect is better, and the unloading and filter cloth cleaning efficiency is high.

[0064] The present invention also provides a material spreading and unloading system composed of a filter cloth laying and unloading winding device 5 and a filter cloth folding-spraying coating device 3, which is used for spreading water-containing materials and unloading dehydrated materials.

[0065] The filter cloth laying and folding-spraying coating equipment 3 is used to lay the filter cloth in the cylinder body 1 - 1 of the filter cylinder module 1 and coat the water-containing material on the filter cloth, wherein the filter cloth carrying the material is provided by the filter cloth laying and unloading and winding equipment 5 .

[0066] The filter cylinder module 1 has two working positions, namely, working position A and working position B. Working position A is located at the filter cloth laying-folding-spraying coating device 3, and is used to lay filter cloth in the cylinder body 1-1 before filtration and to remove the filter cloth with material from the cylinder body 1-1 after filtration. Working position B is located at other positions other than the cloth laying-folding-spraying coating device 3, and is used to press filter the water-containing material in the cylinder body 1-1 to remove moisture. Pressing refers to squeezing and filtering out the water in the water-containing material to achieve material dehydration.

In this way, when the two cloth pressing rods of the rear cloth pressing device 3-5 are respectively inserted into the second groove from the left and right end openings of the second groove, they will not touch the third support seat 3-3-2 of the cloth folding coating device 3-3.

[0087] When the telescopic pressing plate 3-2 is in the upward retracted state and the front cloth presser 3-4 is in the downward moving state, the distance between the two is greater than the thickness of the push plate 3-3-1 of the cloth folding coating device 3-3, and the push plate 3-3-1 can pass through the space between the telescopic pressing plate 3-2 and the front cloth presser 3-4. The thickness of the push plate 3-3-1 refers to the size of the push plate 3-3-1 in the up and down direction.

[0088] When the filter cloth is laid and the water-containing material is coated, the filter cylinder module 1 is located at the working position A, and the lifter 2A-2 extends upward from the lower opening 1-3 at the bottom of the cylinder body 1-1 into the cylinder body 1-1 to support the movable bottom plate 1-2 in the cylinder body 1-1 and lift the movable bottom plate 1-2 to the top of the cylinder body 1-1.

[0089] The filter cloth 3-7 is rolled up on the cloth roll roller 5-13 of the filter cloth unloading and unloading winding device 5, one end of the filter cloth 3-7 is located in the filter cloth roll, the other end of the filter cloth 3-7 is fixed to the rear end of the movable bottom plate 1-2, and the filter cloth 3-7 is laid flat on the movable bottom plate 1-2 located at the top of the cylinder body 1-1, which is the initial state. The other end of the filter cloth can be fixed to the front end or the rear end of the movable bottom plate 1-2. In this embodiment, the other end of the filter cloth is fixed to the rear end of the movable bottom plate 1-2 for example.

[0090] During the cloth laying process, the active guide roller 5-3 and the cloth winding roller 5-13 of the filter cloth laying and unloading and winding device 5 are driven by the motor to transmit the filter cloth, providing a clean and flat filter cloth for the filter cloth folding-spray coating device 3, thereby ensuring the high consistency of the overall device process; Figure 8 , 9 As shown, when the cloth placing process is performed, the wrinkle removal roller 5-6 is in an idle position, the wrinkle removal roller 5-6 does not contact the filter cloth 3-7, and the filter cloth 3-7 is directly transported on the first free guide roller 5-5 and the second free guide roller 5-7 to reduce the transmission resistance.

[0091] While the cloth is being laid, the filter cloth folding-spraying coating device 3 performs the actions of folding, spraying and coating the filter cloth. Filter cloth folding-spraying coating process flow:

[0092] The telescopic pressing plate 3-2 located above the front end of the cylinder body 1-1 extends downward to the top of the cylinder body 1-1 and presses the filter cloth 3-7; the sprayer 3-6 sprays the material onto the surface of the filter cloth 3-7; Figure 8 As shown, the cloth pressing rod 3-4-1 of the front cloth presser extends into the first groove of the telescopic pressing plate 3-2, and the first support seat 3-4-2 of the front cloth presser 3-4 moves downward to make the cloth pressing rod 3-4-1 of the front cloth presser move downward to the top of the cylinder body 1-1, and the cloth pressing rod 3-4-1 of the front cloth presser replaces the telescopic pressing plate 3-2 to press the filter cloth 3-7, and then the telescopic pressing plate 3-2 retracts upward to its original position, and the cloth pressing rod 3-4-1 of the front cloth presser escapes from the first groove from the bottom opening of the first groove of the telescopic pressing plate 3-2 and is separated from the telescopic pressing plate 3-2. At this time, the top of the folding coating device 3-3 is covered with filter cloth 3-7 and the vertical position of the folding coating device 3-3 is higher than the cloth pressing rod 3-4-1 of the front cloth presser. The filter cloth placing and unloading and winding device 5 places the cloth, and the folding coating device 3-3 pushes the filter cloth 3-7 from the front end to the rear end of the cylinder body 1-1. The filter cloth without material sprayed is driven by the folding coating device 3-3 to be placed from the cloth winding roller 5-13 and pulled out from the filter cloth placing and unloading and winding device 5 to cover the aforementioned sprayed material. The material sprayed on the surface of the filter cloth 3-7 is evenly smeared between the upper and lower layers of filter cloth during the process of the folding coating device 3-3 pushing the filter cloth 3-7; Fig. 9As shown, after the cloth folding coating device 3-3 reaches the rear end point of the cylinder body 1-1, the cloth pressing rod 3-5-1 of the rear cloth presser extends from the left and right sides into the second groove of the push plate 3-3-1 of the cloth folding coating device 3-3, and the second support seat 3-5-2 of the rear cloth presser 3-5 moves downward to drive the cloth pressing rod 3-5-1 of the rear cloth presser to the top of the cylinder body 1-1, replacing the cloth folding coating device 3-3 to press the filter cloth 3-7. At this time, the two cloth pressing rods of the rear cloth presser 3-5 slip out of the second groove from the bottom opening of the second groove and separate from the push plate 3-3-1, and then the cloth folding coating device 3-3 returns to its original position. The cloth pressing rod 3-4-1 of the front cloth presser is retracted, and the first support seat 3-4-2 of the front cloth presser 3-4 moves upward and resets; the telescopic pressing plate 3-2 extends downward to the top of the cylinder body 1-1 and presses the filter cloth 3-7; the cloth pressing rod 3-5-1 of the rear cloth presser is retracted, and the second support seat 3-5-2 of the rear cloth presser 3-5 moves upward and resets; the lifting device 2A-2 moves downward to move the movable bottom plate 1-2 downward by a certain distance, and the moving distance is equal to the sum of the thicknesses of the two layers of filter cloth and the material layer. At this time, the upper filter cloth 3-7 is flush with the top of the cylinder body 1-1, and the filter cloth paving and folding-spraying coating process is completed; the above-mentioned filter cloth paving and folding-spraying coating process is repeated, and the material and filter cloth are superimposed layer by layer in the cylinder body 1-1 in a stacked state, such as Fig.10 As shown, two layers of filter cloth are sandwiched between the two layers of material, and the material is evenly spread between the upper and lower layers of filter cloth. Until the cloth is finished, the cloth placing process stops, and at this time, the lifting device 2A-2 is completely retracted and exits the cylinder body 1-1.

[0093] The filter cylinder module 1 moves from the work position A to the work position B, where other equipment extrudes and dehydrates the water-containing material. After the extrusion and dehydration are completed, the filter cylinder module 1 moves from the work position B to the work position A. The lifting device 2A-2 of the work position A lifts upward, so that the material and filter cloth that are still in a stacked state after extrusion and dehydration rise to the top of the cylinder body 1-1.

[0094] When the cloth rolling and unloading process begins, the cloth rolling roller 5-13 and the active guide roller 5-3 in the filter cloth placing and unloading winding device 5 are driven by the motor to rotate, and the rotation direction is opposite to the rotation direction during the cloth placing process, driving the filter cloth 3-7 to move, unloading the filter cloth with material from the cylinder body 1-1, and recovering the filter cloth; the material after extrusion and dehydration is carried on the filter cloth 3-7, and leaves the filter cylinder module 1 together with the filter cloth 3-7 and enters the unloading functional unit in the filter cloth placing and unloading winding device 5.

[0095] The extrusion process causes 3-7 wrinkles in the filter cloth. When the filter cloth is recovered, it passes through the unloading function unit, the filter cloth arranging function unit, and the filter cloth rolling function unit in sequence to complete unloading, flattening, and rolling.

[0096] When in the unloading function unit, the filter cloth 3-7 expands the weft width under the action of the raised lines of the expansion plate 5-1 when passing through the expansion plate 5-1, reducing wrinkles and making the material loosely spread on the surface of the filter cloth; the smaller friction between the smooth conveying plate 5-2 and the filter cloth 3-7 is conducive to the smooth passage of the filter cloth, and also provides tension for the winding of the filter cloth. When the filter cloth 3-7 passes through the active guide roller 5-3, the material on the filter cloth is peeled off by the material conveyor 5-4 and falls into the auger through the inclined surface, and then sent away by the auger to complete the unloading. As the filter cloth is recovered and the material is peeled off, the thickness of the accumulated material and filter cloth in the cylinder 1-1 decreases, and the lifter 2A-2 continues to lift upward to keep the accumulated material and filter cloth always at the top of the cylinder 1-1, so that the unloading process is smooth.

[0097] Subsequently, the filter cloth 3-7 after the material is peeled off passes through the filter cloth finishing functional unit. At this time, the wrinkle removal roller 5-6 is in the working position, and the wrinkle removal roller 5-6 rotates to remove wrinkles from the filter cloth 3-7; then the scrubber 5-8 scrubs the filter cloth 3-7.

[0098] Finally, the filter cloth 3-7 enters the filter cloth winding functional unit, and the filter cloth is wound on the cloth winding roller 5-13 after passing through the positioner 5-11 and the fourth free guide roller 5-12. The positioner 5-11 corrects the position of the filter cloth to prevent deviation, so that the filter cloth is rolled into a neat cloth roll on the cloth winding roller 5-13.

[0099] The material spreading and material unloading system in the present invention is composed of filter cloth spreading and unloading and winding equipment and filter cloth folding-spraying and coating equipment, which are used for water-containing material spreading and dehydrated material unloading, and realize spreading, water-containing material spreading and dehydrated material unloading, and filter cloth winding. The structure is compact and occupies little space. The filter cloth spreading, laying and material spraying are organically connected. The spreading efficiency is high, the spreading is uniform and flat, and the space occupied by the spreading is smaller than that of the spreading method without folding the filter cloth. During the dehydrated material unloading and filter cloth cleaning, flattening and winding process, there is no need to pause, and the work efficiency is high.
