Description

Technical Field

[0001] This utility model relates to the field of cold-rolled strip steel technology, and in particular to an automatic waste filter cloth collection device. Background Technology

[0002] In the production of cold-rolled strip steel, emulsions are widely used as lubricants and coolants in the rolling process, directly affecting the surface quality and rolling stability of the strip steel. To ensure the cleanliness of the emulsion, the recycled emulsion needs to be filtered through a flat-bed filter to remove iron filings brought in during the rolling process and other particulate impurities.

[0003] A flat-bed filter, as a solid-liquid separation filtration device, consists of a waste liquid chamber, a clean liquid chamber, filter cloth, a vacuum negative pressure device, a stainless steel mesh belt conveyor chain, and a drive unit. The waste liquid chamber is separated from the clean liquid tank at the bottom of the housing by the filter cloth on the stainless steel mesh belt conveyor chain and oil-resistant and heat-resistant rubber sealing strips on both sides. The circulating emulsion passes through the filter cloth, enters the clean liquid tank, and flows into the emulsion tank. During the rolling process, impurities accumulate and thicken on the filter cloth, reducing its filtration efficiency. The stainless steel mesh belt rotates periodically, moving the waste filter cloth forward and out of the filter. Automatic collection of waste filter cloth helps improve production efficiency and reduce labor. The recycling of emulsion from the waste filter cloth reduces operating costs and avoids environmental pollution.

[0004] Currently, the most common filter cloth collection device is the filter cloth collection box. For example... Figure 3 As shown, the existing filter cloth collection box 105 is located below the outlet of the flat bed filter. After the waste filter cloth 102 leaves the filter, it falls into the existing filter cloth collection box 105. At the same time, during the falling process, the waste emulsion and waste filter cloth are separated by gravity, and the waste emulsion is collected and discharged through the drain in the collection box. The defects of this technology are: (1) The state of the filter cloth is uncontrollable during the collection process, and there is a possibility that it falls outside the collection box, which requires manual inspection; (2) The filter cloth in the collection box is stacked messily, and the subsequent processing is relatively cumbersome and inefficient; (3) The emulsion and filter cloth fall by gravity, and the stacking method causes the emulsion to only gradually penetrate from the upper waste filter cloth to the lower waste filter cloth, which makes the separation of emulsion and filter cloth incomplete. The filter cloth in the collection box will still have residual emulsion, and the separation effect is not good.

[0005] Therefore, based on years of experience and practice in related industries, the inventor proposes an automatic waste filter cloth collection device to overcome the shortcomings of existing technologies. Utility Model Content

[0006] The purpose of this invention is to provide an automatic waste filter cloth collection device that overcomes the problems of disordered waste filter cloth collection and poor emulsion separation in the prior art. This invention realizes automated and controllable collection of waste filter cloth, improves the efficiency of collection and replacement processes, and reduces the workload of workers in disassembly and assembly. At the same time, it reduces the residual emulsion on the waste filter cloth and effectively improves the separation effect.

[0007] The purpose of this utility model is achieved as follows: an automatic waste filter cloth collection device includes a mandrel for tensioning and winding waste filter cloth, the mandrel being supported in a support opening of a tensioning mechanism, the tensioning mechanism being adjustable by moving horizontally along the mandrel; a width adjustment mechanism is connected to the tensioning mechanism to adjust the size of the support opening; a drive mechanism is connected to the mandrel to drive the mandrel to rotate; and a waste liquid collection tank for collecting waste emulsion is provided below the mandrel.

[0009] In a preferred embodiment of this utility model, the active-side filter element support shaft is hinged to the active-side bearing seat; the driven-side filter element support shaft is hinged to the driven-side bearing seat; a support shaft bearing seat positioning device is connected to both the active-side bearing seat and the driven-side bearing seat, and the support shaft bearing seat positioning device adjusts the position of the active-side bearing seat and the driven-side bearing seat along the horizontal radial direction of the spindle.

[0010] In a preferred embodiment of this utility model, an active side bearing is provided in the active side bearing housing, an active side connecting shaft passes through the active side bearing, a first end of the active side connecting shaft is connected to the drive mechanism, and a second end of the active side connecting shaft is provided with the active side filter element support shaft.

[0011] In a preferred embodiment of the present invention, the drive mechanism includes a chain and a sprocket. The sprocket is coaxially arranged with the active side filter element support shaft. One end of the chain is sleeved on the sprocket, and the other end of the chain is sleeved on the power unit.

[0012] In a preferred embodiment of this utility model, the power unit is a filter cloth drive unit for a flat bed filter.

[0013] In a preferred embodiment of this utility model, the driving mechanism is a drive motor, a hydraulic motor, or a pneumatic motor, and the output shaft of the drive motor, the hydraulic motor, or the pneumatic motor is connected to the active side filter element support shaft.

[0014] In a preferred embodiment of this utility model, the bearing housing positioning device is a positioning adjustment bolt disposed on both sides of the active side bearing housing and the driven side bearing housing along the horizontal radial direction of the mandrel.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figure 1 , Figure 2 As shown, this utility model provides an automatic waste filter cloth collection device, including a mandrel 60 for tensioning and winding waste filter cloth 102. The mandrel 60 is supported in the support opening of the tensioning mechanism 30, which can be adjusted by moving horizontally along the mandrel 60. A width adjustment mechanism 40 is connected to the tensioning mechanism 30 to adjust the size of the support opening. A drive mechanism 20 is connected to the mandrel 60 to drive the mandrel 60 to rotate. A waste liquid collection tank 50 for collecting waste emulsion is provided below the mandrel 60.

[0027] In this invention, the mandrel 60 rotates under the drive of the drive mechanism 20 to wind up the waste filter cloth 102, realizing the automatic winding and collection of the waste filter cloth 102. The collection process is stable and orderly, preventing the waste filter cloth 102 from falling off. Furthermore, the mandrel 60 is adjusted in position by the tensioning mechanism 30 to provide tension to the waste filter cloth 102. During the winding process of the waste filter cloth 102, this tension can improve the separation effect of the emulsion and reduce the residue of emulsion in the waste filter cloth 102 (waste material). The separated emulsion falls directly into the waste liquid collection box 50 below the mandrel 60 and will not seep into the waste filter cloth 102 near the mandrel 60 (winding core). The tensioning mechanism 30 is connected to the width adjustment mechanism 40, which can adjust the support opening, so that the device can adapt to multiple specifications of mandrel 60 and improve the versatility of the device.

[0028] This invention enables automated and controllable collection of waste filter cloth, improving efficiency in the collection and replacement process and reducing the workload of workers in disassembly and assembly; at the same time, it reduces the residual emulsion on the waste filter cloth, effectively improving the separation effect.

[0029] This invention is applicable to flatbed filters, and is also suitable for other types of filters. It can be used to collect any relatively flexible material.

[0030] Furthermore, such as Figure 2 As shown, the tensioning mechanism 30 includes an active side filter element support shaft 301 and a driven side filter element support shaft 302 arranged opposite to each other. The two ends of the spindle 60 are supported on the active side filter element support shaft 301 and the driven side filter element support shaft 302. The active side filter element support shaft 301 is connected to the drive mechanism 20, and the drive mechanism 20 drives the spindle 60 to rotate through the active side filter element support shaft 301.

[0031] The tensioning mechanism 30 can also use hydraulic cylinders or pneumatic cylinders to achieve real-time controllable adjustment of the positioning and tension of the spindle 60.

[0032] Furthermore, such as Figure 2 As shown, the active side filter element support shaft 301 is hinged to the active side bearing seat 304; the driven side filter element support shaft 302 is hinged to the driven side bearing seat 305; both the active side bearing seat 304 and the driven side bearing seat 305 are connected to a support shaft bearing seat positioning device 303, which adjusts the position of the active side bearing seat 304 and the driven side bearing seat 305 along the horizontal radial direction of the spindle 60.

[0033] Furthermore, such as Figure 2 As shown, an active side bearing is provided in the active side bearing housing 304, and an active side connecting shaft 306 passes through the active side bearing. The first end of the active side connecting shaft 306 is connected to the drive mechanism 20, and the second end of the active side connecting shaft 306 is provided with an active side filter element support shaft 301.

[0034] Furthermore, the drive structure can take many forms.

[0035] like Figure 1 As shown, the drive mechanism 20 can use a chain 201 and a sprocket 202. The sprocket 202 is coaxially arranged with the active side filter element support shaft 301. One end of the chain 201 is sleeved on the sprocket 202, and the other end of the chain 201 is sleeved on the power unit. The drive mechanism 20 can use a belt drive or other transmission method instead of a chain drive.

[0036] The power unit can be the filter cloth drive unit of the flat bed filter, or it can be an independently set power device.

[0037] In one specific embodiment, such as Figure 1 As shown, the drive device 104 of the flat bed filter drives the sprocket 202 and the coaxial active side filter element support shaft 301 to rotate via the chain 201, thereby driving the rotation of the core shaft 60 and realizing the automatic roll-up collection of waste filter cloth 102.

[0038] The drive mechanism can also be a separately set drive motor, hydraulic motor or pneumatic motor, and the output shaft of the drive motor, hydraulic motor or pneumatic motor is connected to the active side filter element support shaft 301.

[0039] Furthermore, such as Figure 1 As shown, the bearing housing positioning device 303 can be a positioning adjustment bolt installed on both sides of the mandrel along the horizontal radial direction of the active side bearing housing 304 and the driven side bearing housing 305.

[0040] In one specific embodiment, such as Figure 1As shown, the bearing housing positioning device 303 adjusts the horizontal position of the active side bearing housing 304 and the driven side bearing housing 305 through two front and rear positioning adjustment bolts, which can simultaneously ensure the tension of the chain 201 and the waste filter cloth 102.

[0041] Furthermore, a thickness detection structure is provided on the active side filter element support shaft 301 and / or the driven side filter element support shaft 302 to realize real-time monitoring of the waste filter cloth collection. The thickness detection structure can be a thickness sensor.

[0042] Furthermore, the width adjustment mechanism 40 can adopt various structural forms.

[0043] like Figure 2 As shown, the width adjustment mechanism 40 includes a handwheel 401, a lead screw 402, and a lead screw seat 403. The lead screw 402 rotates through the lead screw seat 403. The end of the lead screw 402 can be connected to the active side filter element support shaft 301 or the driven side filter element support shaft 302. By rotating the handwheel 401, the lead screw 402 is rotated to push and pull along the axial direction of the spindle 60 to adjust the active side filter element support shaft 301 or the driven side filter element support shaft 302.

[0044] In one specific embodiment, the driven side filter element support shaft 302 is adjusted by rotating the handwheel 401 to accommodate mandrels 60 of different widths, and the mandrel 60 is clamped with the active side filter element support shaft 301 and the driven side filter element support shaft 302 to achieve synchronous rotation.

[0045] The width adjustment mechanism 40 can also be a hydraulic push-pull cylinder or a pneumatic push-pull cylinder. The hydraulic push-pull cylinder or the pneumatic push-pull cylinder can push and pull along the axial direction of the spindle 60 to adjust the active side filter element support shaft 301 or the driven side filter element support shaft 302, so as to realize real-time controllable adjustment of different filter cloth widths.

[0046] Furthermore, such as Figure 1 , Figure 2 As shown, the waste liquid collection tank 50 is a welded tank with a drain port equipped with a valve. This drain port can guide the waste emulsion back to the emulsion return tank (existing technology) or discharge it into a ditch.

[0047] Example: like Figure 1 , Figure 2 As shown, this embodiment provides an automatic waste filter cloth collection device applied to the flat bed filter 10. The flatbed filter 10 includes at least a flatbed filter housing 101, waste filter cloth 102, a stainless steel mesh belt conveyor chain 103, and a drive unit 104. The waste filter cloth 102, the stainless steel mesh belt conveyor chain 103, and the drive unit 104 are all fixed to the flatbed filter housing 101. The motor in the drive unit 104 drives the stainless steel mesh belt conveyor chain 103 to rotate periodically, pulling the waste filter cloth 102 to move out of the flatbed filter.

[0048] The drive mechanism 20 consists of a chain 201 and a sprocket 202. The drive device 104 of the flat bed filter (which constitutes the aforementioned power unit) drives the sprocket 202 and the coaxial active side filter element support shaft 301 to rotate through the chain 201, thereby driving the rotation of the core shaft 60 and realizing the automatic roll-up collection of waste filter cloth 102.

[0049] The tensioning mechanism 30 consists of an active-side filter element support shaft 301, a driven-side filter element support shaft 302, and a support shaft bearing seat positioning device 303. The support shaft bearing seat positioning device 303 adjusts the horizontal position of the bearing seat through two front and rear positioning adjustment bolts, ensuring the tension of both the chain 201 and the waste filter cloth 102. During the curling process of the waste filter cloth 102, this tension force improves the separation effect of the emulsion, reduces the residue of emulsion in the waste filter cloth 102, and the separated emulsion falls directly into the waste liquid collection tank 50 without seeping into the waste filter cloth 102 near the spindle 60.

[0050] The width adjustment mechanism 40 consists of a handwheel 401, a lead screw 402, and a lead screw seat 403. By rotating the handwheel 401, the driven side filter element support shaft 302 is adjusted to accommodate mandrels 60 of different widths, and the mandrel 60 is clamped with the active side filter element support shaft 301 and the driven side filter element support shaft 302 to achieve synchronous rotation.

[0051] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
