Description

Technical Field

[0001] This invention relates to the field of glass product manufacturing technology, and in particular to a scissor coolant recycling system. Background Technology

[0002] In the glass manufacturing process, droplet formation is the first step in the glass forming process. Droplet formation involves ensuring the molten glass has a suitable and uniform temperature. Under the mechanical action of the barrel, bowl, punch, and shears, the molten glass forms a droplet, meeting the forming requirements. The molten glass flowing from the bowl is cut by the overlapping and closing of the upper and lower shear blades, forming a glass droplet. To ensure the sharpness of the shear blades, their temperature must not be too high; otherwise, poor shearing will occur. When poor shearing occurs, glass shear marks may appear at two points on the droplet. These shear marks will magnify during the forming and blowing process, forming "scissor marks." These marks can affect the appearance or even become the source of cracks. Therefore, cooling treatment of the shear blades is necessary.

[0003] Spraying scissor blades with coolant is a common method for cooling them. Currently, after the coolant is sprayed, the coolant flowing down from the blades is directly discharged into the wastewater treatment system for treatment through pipelines. However, this increases manufacturing costs and the technical requirements and treatment capacity of the wastewater treatment system. Summary of the Invention

[0004] The purpose of this invention is to provide a scissor coolant recycling system to solve the problem of increasing production costs and wastewater treatment volume caused by directly discharging scissor coolant into the wastewater treatment system through pipelines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The scissor coolant recycling system of the present invention includes:

[0007] A collection tray, the bottom of which is provided with a first liquid outlet, a filter container is detachably installed at the first liquid outlet, the top of the filter container is open, and a through hole is provided on the container wall of the filter container, the diameter of the through hole gradually decreasing from the inside of the container wall to the outside of the container wall.

[0008] A filter bend, one end of which is detachably connected to the first liquid outlet, and the other end of which is detachably connected to an infusion tube. The filter bend is provided with at least two bends, and the bends connected to the first liquid outlet protrude downwards.

[0009] The liquid collection tank is provided with an inlet and a second outlet. The inlet is connected to the delivery pipe. A filter assembly is provided inside the liquid collection tank for filtering the scissor coolant in the liquid collection tank.

[0010] An infusion assembly is connected to the second outlet to discharge the filtered scissor coolant from the collection tank.

[0011] Preferably, the top of the filter container is fixed with a support ear and a handle, the support ear extends radially along the filter container and is mounted on the bottom of the collection tray, and the handle extends upward to the top of the filter container.

[0012] Preferably, the filtration assembly includes a sedimentation funnel and a filter screen. The filter screen is detachably connected to the inner wall of the collection tank. The filter screen divides the collection tank into a first collection space and a second collection space. The second outlet is located in the first collection space. The sedimentation funnel is located in the second collection space, and the inlet of the sedimentation funnel is located below the inlet of the infusion tube.

[0013] Preferably, the infusion assembly includes a delivery pipeline, a pump, and a level monitoring mechanism. The delivery pipeline is connected to the second outlet, the pump is installed on the delivery pipeline, and the level monitoring mechanism is installed inside the collection tank.

[0014] Preferably, the infusion assembly further includes a controller, and the pump and the liquid level monitoring mechanism are both electrically connected to the controller.

[0015] Preferably, the bend is U-shaped, with the U-shaped opening of the bend connected to the first outlet facing upwards, and the U-shaped opening of the bend connected to the infusion tube facing downwards.

[0016] Preferably, the scissor coolant recycling system further includes a flow monitoring mechanism, which is installed on the infusion pipe.

[0017] Preferably, multiple collection trays are provided, each collection tray is connected to a filter bend and an infusion tube, and all the infusion tubes converge into an infusion manifold, which is connected to the infusion port.

[0018] Preferably, the scissor coolant recycling system further includes a storage container connected to the infusion assembly.

[0019] Compared with the prior art, the scissor coolant recycling system of this invention has the following advantages:

[0020] The scissor coolant recycling system of this invention collects the scissor coolant flowing from the scissor blades through a collection tray, and then transports the scissor coolant to a collection tank through a filter bend. The filter bend has at least two bends, which can store a portion of the scissor coolant. When high-temperature molten glass mixed in the scissor coolant flows in, it will instantly solidify, preventing the molten glass from flowing into the collection tank. After being further filtered by the filter assembly in the collection tank, the scissor coolant is discharged through the liquid delivery assembly and can be used as new coolant. This completes the recycling process of collecting, filtering, and transporting the scissor coolant, eliminating the need to send it to a sewage treatment system, saving production costs, and reducing sewage discharge and treatment volume.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] like Figure 1 - Figure 6 As shown, an embodiment of the present invention provides a scissor coolant recycling system, comprising a collection tray 1, a filter bend 2, a collection tank 4, and a delivery assembly 6. The collection tray 1 is located below the scissor arms 8 of a rotary machine and is used to collect the scissor coolant flowing down from the sprayed cooling scissor arms 8. A first outlet is located at the bottom of the collection tray 1. One end of the filter bend 2 is detachably connected to the first outlet, and the other end is detachably connected to a delivery pipe 3. The filter bend 2 has at least two bends 21. The bend 21 connected to the first outlet protrudes downwards and can store a portion of the scissor coolant. When the scissor coolant flowing from the first outlet is clamped... When high-temperature molten glass is present, the molten glass enters the filter bend 2 and is instantly solidified by the cooling fluid in the bend 21, preventing it from flowing into the downstream delivery pipe 3. The collection tank 4 is equipped with an inlet and a second outlet. The inlet is connected to the delivery pipe 3. The collection tank 4 is equipped with a filter assembly 5, which is used to filter the cooling fluid in the collection tank 4. The cooling fluid in the delivery pipe 3 enters the collection tank 4 through the inlet, is filtered by the filter assembly 5, and then flows out through the second outlet. The delivery assembly 6 is connected to the second outlet to discharge the filtered cooling fluid in the collection tank 4 for use as new cooling fluid.

[0033] This invention enables a cyclical process for the collection, filtration, and transportation of scissor coolant, eliminating the need to send residual scissor coolant into a wastewater treatment system, thus saving production costs and reducing wastewater discharge and treatment volume.

[0034] In this embodiment, the scissor coolant recycling system also includes a storage container 7, which is connected to the infusion assembly 6. The storage container 7 receives and stores the scissor coolant delivered by the infusion assembly 6. The storage container 7 can also be used as a scissor coolant filling container to spray new scissor coolant onto the scissor arms 8.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, a filter container 11 is detachably installed at the first outlet. The top of the filter container 11 is open, and a through hole 111 is formed on the container wall. The diameter of the through hole 111 gradually decreases from the inner side of the container wall to the outer side. The cross-section of the through hole 111 is conical, and the central axis of the conical through hole is set along the radial or axial direction of the filter container 11. The filter container 11 is used to perform preliminary filtration of the scissor coolant collected in the collection tray 1. During the changeover and normal production of the machine, glass melt or debris inevitably falls into the collection tray 1. By performing preliminary filtration of the scissor coolant through the filter container 11, it is possible to prevent the glass melt from flowing into the pipeline and solidifying, and to prevent large particles of debris from clogging the pipeline and causing accidents. By setting the through hole 111 of the filter container 11 to be conical with a larger inner diameter and a smaller outer diameter, the high-temperature glass melt will slowly solidify after flowing into the filter container 11. The conical shape of the through hole will create resistance to the flow of the glass melt, preventing the glass melt from flowing into the subsequent pipeline and causing pipeline blockage.

[0036] Furthermore, such as Figure 4 and Figure 5 As shown, the top of the filter container 11 is fixed with a support ear 12 and a handle 13. The support ear 12 extends radially along the filter container 11 and is mounted on the bottom of the collection tray 1. The handle 13 extends upward to the top of the filter container 11, which facilitates the quick loading and unloading of the filter container 11 and the cleaning of the solidified glass liquid inside the filter container 11, avoiding the inability to disassemble during high-temperature processes.

[0037] In this embodiment, as Figure 3 and Figure 6 As shown, both ends of the filter bend 2 are connected to the first liquid outlet and the infusion tube 3 respectively via quick-release clips 22, facilitating quick disassembly of the filter bend 2 and periodic cleaning of the solidified glass inside the filter bend 2 and the particulate matter deposited in the bend 21. When replacing and cleaning the filter bend 2, first remove the filter container 11, plug the first liquid outlet of the collection tray 1 with the plug, then disassemble the filter bend 2. After replacement and cleaning, remove the plug and put it back into the filter container 11.

[0038] In this embodiment, the filter bend 2 is a corrugated pipe, installed horizontally. For example... Figure 3 As shown, the bend 21 is U-shaped. The U-shaped opening of the bend 21 connected to the first liquid outlet is set upward so as to store part of the scissor coolant in the bend 21 to cool the high-temperature glass liquid entering the filter bend 2. The U-shaped opening of the bend 21 connected to the liquid delivery pipe 3 is set downward so as to facilitate the flow of scissor coolant from the filter bend 2 into the liquid delivery pipe 3.

[0039] In this embodiment, the scissor coolant recycling system also includes a flow monitoring mechanism 23, which can be a flow meter. The flow monitoring mechanism 23 is installed on the infusion pipe 3 and is used to monitor the flow rate within the infusion pipe 3, facilitating the detection of blockages in the filter bend 2. When a blockage occurs in the filter bend 2, no scissor coolant flows into the infusion pipe 3. Therefore, the flow monitoring mechanism 23 can detect whether the filter bend 2 is blocked, promptly alerting operators to repair or replace it, thus avoiding the risk of scissor coolant overflow.

[0040] In this embodiment, the collection tray 1, the filter container 11, and the filter bend 2 can all be quickly disassembled. When changing production or replacing parts during maintenance of the production line, it is necessary to remove components such as the collection tray 1. If the collection tray 1 cannot be removed at any time, it may lead to a safety accident. Setting the connection of each component as a quick-release structure is convenient and flexible, minimizing the time required for production changeover and maintenance.

[0041] In this embodiment, the filter assembly 5 includes a settling funnel 51 and a filter screen 52. The filter screen 52 is detachably connected to the inner wall of the collection tank 4 for easy replacement and cleaning. The filter screen 52 divides the collection tank 4 into a first collection space and a second collection space. The second outlet is located in the first collection space, and the settling funnel 51 is located in the second collection space, with its inlet located below the opening of the infusion pipe 3. The filter screen 52 can be vertically installed in the collection tank 4. When the scissor coolant enters the collection tank 4, it first enters the settling funnel 51. Larger and heavier particles naturally settle in the settling funnel 51. Because the nozzle diameter of the scissor coolant is very small, the scissor coolant itself will condense into flocculent matter. If there are particles, it can cause nozzle blockage and accidents. The settled scissor coolant overflows into the collection tank 4 and is further filtered by the filter screen 52. The filtered scissor coolant can then be used as new coolant. Furthermore, a drain pipe is connected to the bottom of the collection tank 4, and a drain valve 41 is installed on the drain pipe to facilitate regular cleaning of the collection tank 4.

[0042] In this embodiment, the infusion assembly 6 includes a delivery pipe 61, a pump 62, and a level monitoring mechanism 63. The delivery pipe 61 is connected to a second outlet, the pump 62 is installed on the delivery pipe 61, and the level monitoring mechanism 63 is installed inside the collection tank 4. The level monitoring mechanism 63 monitors the level in the collection tank 4, the pump 62 extracts the scissor coolant from the collection tank 4, and the coolant is discharged from the collection tank 4 through the delivery pipe 61. The level monitoring mechanism 63 is a level gauge.

[0043] The liquid level monitoring mechanism 63 is equipped with low-level detection, high-level detection, and ultra-high-level detection. When the liquid level in the collection tank 4 reaches the high-level set value, the pump 62 is activated to extract the scissor coolant from the collection tank 4 and transport it to the storage container 7 through the delivery pipe 61. When the liquid level in the collection tank 4 drops to the low-level set value, the pump 62 stops working, and the collection tank 4 collects and settles the scissor coolant, repeating the cycle as above. In case of equipment failure or abnormality, to prevent the pump 62 from failing to start properly and causing scissor coolant overflow when the scissor coolant in the collection tank 4 reaches the high-level set value, the liquid level monitoring mechanism 63 is also equipped with an ultra-high-level detection. When the liquid level in the collection tank 4 reaches the ultra-high-level set value, the liquid level monitoring mechanism 63 issues a fault alarm to promptly remind maintenance personnel to handle the situation.

[0044] To prevent the scissor coolant in the delivery pipe 61 from flowing back after the pump 62 stops supplying liquid each time, a one-way check valve 611 is installed on the delivery pipe 61 at the rear end of the pump 62.

[0045] Furthermore, the infusion assembly 6 also includes a controller 64, and the pump 62 and the level monitoring mechanism 63 are both electrically connected to the controller 64. The level monitoring mechanism 63 transmits the monitored level signal to the controller 64, which then controls the start and stop of the pump 62 to achieve automated control of the cyclic operation and improve the degree of automation.

[0046] In this embodiment, multiple collection trays 1 are provided. Each collection tray 1 is connected to a filter bend 2 and a delivery pipe 3. Each delivery pipe 3 is connected to a collection tank 4 and a delivery assembly. The delivery pipes 61 of each delivery assembly are connected to the same storage container 7. After the scissor coolant is processed by the collection trays 1, filter bends 2, delivery pipes 3, and collection tanks 4, the scissor coolant that can be used as new coolant is collected into the storage container 7 for later use. Each collection tray 1 is equipped with a matching filter container 11, filter bend 2, delivery pipe 3, collection tank 4, and delivery assembly 6, so that the processing paths of the scissor coolant in each collection tray 1 do not interfere with each other, facilitating individual disassembly and repair of faulty components.

[0047] Optionally, such as Figure 7As shown, multiple collection trays 1 are provided, each connected to a filter bend 2 and a delivery pipe 3. All delivery pipes 3 converge into a main delivery pipe 31, which is connected to an inlet. After the scissor coolant in each collection tray 1 is treated by the filter bends 2, it is collected through the main delivery pipe 31 and then transported to the collection tank 4 for further centralized filtration and delivery. Treating the scissor coolant in each collection tray 1 separately using individual filter bends 2 avoids clogging the main delivery pipe 31 with molten glass and large particles mixed in with the scissor coolant in the collection trays 1. If a single filter bend 2 becomes clogged, it can be removed individually without affecting the use of other collection trays 1 and filter bends 2. The scissor coolant treated by each filter bend 2 is first collected in the main delivery pipe 31 and then uniformly filtered, reducing the number of collection tanks 4 and delivery components required and saving manufacturing costs.

[0048] The working process of this invention is as follows:

[0049] The coolant flowing from the scissor arm 8 is collected by the collection tray 1. The coolant is initially filtered by the filter container 11 and then flows into the filter bend 2. After further filtration to remove the high-temperature molten glass, the coolant flows into the delivery pipe 3 and into the collection tank 4. The coolant first settles in the settling funnel 51 within the collection tank 4. The settled coolant overflows into the collection tank 4 and is further filtered by the filter screen 52. The treated coolant can then be used as fresh coolant. When the liquid level in the collection tank 4 reaches the high level setpoint of the level gauge, the controller 64 starts the pump 62 to pump the coolant from the collection tank 4 into the storage container 7 for spraying to cool the scissor arm 8. When the liquid level drops to the low level setpoint of the level gauge, the controller 64 stops the pump 62, and the collection tank 4 collects and settles the coolant, repeating the cycle as described above.

[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
