Description

[0002] In the float glass production process, tin ash will appear in the tin bath more or less. The main reason for the tin ash is that the liquid tin in the tin bath, if the oxygen content therein exceeds 5ppm, along with the cooling process from the inlet to the outlet of the tin bath, the tin liquid will have solid tin oxide precipitated. The formed tin oxide slag will cause mechanical scratches to the lower surface of the glass ribbon. Therefore, it is necessary to clean the tin ash in the tin bath regularly.

Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, the meaning of "multiple groups" is two groups or more, the meaning of "multiple pieces" is two pieces or more, and the meaning of "several" is one or more, unless otherwise explicitly and specifically limited.

[0040] In the float glass production process, there will be more or less tin ash in the tin bath. The main reason for the tin ash is the liquid tin in the tin bath. If the oxygen content in it exceeds 5ppm, along with the cooling process from the inlet to the outlet of the tin bath, the tin liquid will have solid tin oxide precipitated. The formed tin oxide slag will cause mechanical scratches on the lower surface of the glass ribbon. Therefore, it is necessary to clean the tin ash in the tin bath regularly.

[0041] At present, the tin ash in the tin bath is mainly cleaned by using a board rake to scrape the slag at the slag pool at the outlet of the tin bath along the pre-set slope. Although this operation method can clean most of the tin ash, the cleaning operation takes a long time, and long-term cleaning operation will cause oxidation of the tin liquid and increase the generation of tin ash.

[0042] Based on this, the embodiments of the present application provide a tin ash collecting device to solve the above problems.

[0043] Reference Figures 1 to 5 The tin ash collecting device provided by the embodiments of the present application includes an absorption assembly 1, a pipe assembly 2, a pump body, and a containing piece 4. The absorption assembly 1 includes an ash suction piece 11, which is arranged above the tin liquid surface of the tin bath 100 at intervals. The ash suction piece 11 is provided with an ash suction channel 111. An ash suction port 112 of the ash suction channel 111 is arranged on the side of the ash suction piece 11 facing the tin liquid surface. The ash suction port 112 is used to suck the tin ash floating on the tin liquid surface into the ash suction channel 111. The pipe assembly 2 is in communication with the ash suction channel 111. The pump body is connected with the pipe assembly 2. When the pump body is opened, a negative pressure is formed at the ash suction port 112, so that the ash suction port 112 can absorb the tin ash. The containing piece 4 is provided with a containing cavity. The containing cavity is in communication with the pipe assembly 2, and is used to contain the tin ash.

[0044] The tin ash collecting device is provided with the tin ash collecting device including the absorption assembly 1, the pipe assembly 2, the pump body and the containing member 4, when the pump body is opened, the tin ash floating on the tin liquid surface can be sucked into the ash suction channel 111 under the action of the air pressure, so that the tin ash is collected by the containing member 4, thus, the tin ash floating on the tin liquid surface can be quickly collected, the working time is shortened, and the tin ash generated in the working process is reduced; in addition, the ash suction member 11 of the absorption assembly 1 is spaced from the tin liquid surface, the direct contact between the ash suction member 11 and the tin liquid is reduced, the amount of tin liquid in the containing cavity is reduced, and thus the loss of the tin liquid is reduced.

[0045] With reference to Figure 2 In some embodiments, the pipe assembly 2 includes the ash suction pipe 21 and the air inlet pipe 22 in communication with the ash suction pipe 21, the ash suction pipe 21 includes the first segment 211 and the second segment 212 connected in sequence, the first segment 211 is in communication with the ash suction channel 111, the second segment 212 is in communication with the containing cavity, the side wall of the second segment 212 is provided with an opening, one end of the air inlet pipe 22 is in communication with the opening, the other end of the air inlet pipe 22 is connected with the pump body, the pump body sends the gas to the air inlet pipe 22 when the pump body is opened, and the angle between the air inlet pipe 22 and the central axis of the first segment 211 is an acute angle, so that the gas entering the ash suction pipe 21 from the opening can flow towards the containing cavity, so as to drive the gas in the first segment 211 to flow towards the second segment 212.

[0046] It should be noted that, since the angle between the air inlet pipe 22 and the central axis of the first segment 211 is an acute angle, after the gas in the air inlet pipe 22 flows into the second segment 212 from the opening, the resistance of the gas flowing to the side of the first segment 211 is greater, and the resistance of the gas flowing to the side of the containing cavity is smaller, so that the part of the gas flows towards the side of the containing cavity, and can drive the gas in the second segment 212 to also flow to the containing cavity, so that the gas in the second segment 212 is in a flowing state, the gas in the second segment 212 can drive the gas in the first segment 211 to flow, so that the gas in the first segment 211 can flow to the second segment 212, thereby reducing the air pressure in the first segment 211, driving the gas in the ash suction channel 111 to flow into the first segment 211, so that the ash suction port 112 can form a negative pressure, and the collection of the tin ash is realized.

[0047] By providing the ash suction pipe 21 and the air inlet pipe 22 in communication with the ash suction pipe 21, connecting the two ends of the ash suction pipe 21 with the ash suction channel 111 and the containing cavity respectively, and connecting the air inlet pipe 22 with the pump body, the tin ash entering the ash suction pipe 21 from the ash suction channel 111 can directly flow to the containing cavity without passing through the pump body, so that the influence of the tin ash on the operation of the pump body can be reduced, and the probability of damage to the pump body by the tin ash is reduced.

[0048] With reference to Figure 3In some embodiments, the angle θ between the air inlet pipe 22 and the central axis of the first section 211 is 40°-50°. By setting the angle θ between the air inlet pipe 22 and the central axis of the first section 211 to be between 40° and 50°, the resistance of the gas in the air inlet pipe 22 flowing towards the side of the accommodation cavity can be reduced, thereby facilitating the flow of the gas in the air inlet pipe 22 to the accommodation cavity, and further enabling the first section 211 to form a negative pressure.

[0049] For example, the angle θ between the air inlet pipe 22 and the central axis of the first section 211 can be 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, or 50°.

[0050] Referring to Figure 1 In some embodiments, the outer side of the dust suction pipe 21 is provided with a handle 214. By providing the handle 214 on the outer side of the dust suction pipe 21, the worker can easily grasp and adjust the position of the dust suction pipe 21, thereby facilitating the dust suction operation.

[0051] Referring to Figure 1 and Figure 2 The side of the dust suction member 11 facing the tin liquid surface is a flat surface, and the side of the dust suction pipe 21 facing the tin liquid surface with respect to the dust suction member 11 is inclined. By inclining the side of the dust suction pipe 21 facing the tin liquid surface with respect to the dust suction member 11, i.e., by inclining the dust suction pipe 21 with respect to the horizontal plane, the worker can stand outside the tin bath 100 and move the dust suction member 11 through the dust suction pipe 21, thereby facilitating the dust suction operation.

[0052] In some embodiments, the dust suction pipe 21 is a hard pipe, and the material of the dust suction pipe 21 can be plastic, metal, etc. For example, the dust suction pipe 21 can be a galvanized pipe, and the model of the dust suction pipe 21 can be DN25. In some embodiments, the air inlet pipe 22 can be integrally formed with the dust suction pipe 21, and the material of the air inlet pipe 22 can be the same as that of the dust suction pipe 21. The total weight of the air inlet pipe 22 and the dust suction pipe 21 can be 15 kg.

[0053] Referring to Figure 4 and Figure 5 In some embodiments, the dust suction passage 111 is trumpet-shaped, and the cross-sectional size of the end of the dust suction passage 111 communicating with the pipe assembly 2 is smaller than the size of the dust suction port 112.

[0054] By setting the dust suction passage 111 to be trumpet-shaped and the cross-sectional size of the end of the dust suction passage 111 communicating with the pipe assembly 2 to be smaller than the size of the dust suction port 112, the size of the dust suction port 112 can be increased, which helps to improve the operation range of the dust absorption assembly 1, thereby improving the operation efficiency.

[0055] In some embodiments, the cross section of the dust suction member 11 can be rectangular, and the cross section of the dust suction passage 111 can also be rectangular, so that the shape of the dust suction member 11 can be adapted to the shape of the tin bath 100, thereby improving the collection effect of tin dust.

[0056] In some embodiments, the size of the dust suction port 112 can be 40mm*40mm.

[0057] With reference to Figure 6 and Figure 7 In some embodiments, the dust absorption assembly 1 further comprises a positioning rod 12, one end of the positioning rod 12 is connected to the dust suction member 11, and the other end of the positioning rod 12 is used to be inserted into the tin bath 100 and abut against the bottom of the tin bath 100, so that the side of the dust suction member 11 facing the tin liquid surface is spaced apart from the tin liquid surface.

[0058] In the present embodiment, the side of the dust suction member 11 facing the tin liquid surface is arranged to be spaced apart from the tin liquid surface, so that the amount of tin liquid entering the dust suction passage 111 can be reduced, thereby reducing the loss of tin liquid; the positioning rod 12 connected to the dust suction member 11 is arranged, and the end of the positioning rod 12 away from the dust suction member 11 is inserted into the tin bath 100 and abuts against the bottom of the tin bath 100, so that the positioning rod 12 can be used for positioning the position between the dust suction member 11 and the tin bath 100, thereby reducing the risk of the side of the dust suction member 11 facing the tin liquid surface being immersed in the tin liquid.

[0059] With reference to Figure 6 and Figure 7 In some embodiments, the dust absorption assembly 1 comprises two positioning rods 12, the two positioning rods 12 are arranged to be spaced apart along a first direction, the first direction is perpendicular to the moving direction of the dust suction member 11, the positioning rod 12 is provided with a guide surface 124, the guide surfaces 124 of the two positioning rods 12 are arranged to be opposite to each other, and the guide surface 124 is arranged to be inclined with respect to a second direction, the second direction is parallel to the moving direction of the dust suction member 11, so that when the dust suction member 11 moves, the guide surface 124 can guide the tin dust floating on the tin liquid surface to move towards the dust suction port 112.

[0060] It can be understood that the size of the dust suction port 112 is smaller than the size of the tin bath 100, and in the process of collecting tin dust, the dust suction member 11 needs to be moved to collect tin dust in different regions of the tin bath 100; the guide surface 124 is arranged to be inclined with respect to the second direction, that is, the guide surface 124 is arranged to be inclined with respect to the moving direction of the dust suction member 11, so that when the dust suction member 11 moves, the guide surface 124 can guide the tin dust floating on the tin liquid surface to move towards the dust suction port 112, thereby helping to collect the tin dust floating on the tin liquid surface to the dust suction port 112, and helping to improve the collection efficiency of tin dust.

[0061] In some embodiments, the end of the positioning rod 12 away from the dust suction member 11 is provided with a roller 13, and the roller 13 is used to roll on the bottom of the tin bath 100.

[0062] It is understandable that the size of the suction port 112 is smaller than the size of the solder bath 100. During the process of collecting solder ash, it is necessary to move the suction component 11 to collect solder ash in different areas of the solder bath 100. A roller 13 is provided at the end of the positioning rod 12 away from the suction component 11. When the roller 13 rolls at the bottom of the solder bath 100, it can reduce the resistance of the positioning rod 12, thereby facilitating the adjustment of the position of the suction component 11 and helping to improve the efficiency of solder ash collection.

[0063] Reference Figure 8 In some embodiments, the positioning rod 12 is a telescopic rod, which includes a first rod body 121 and a second rod body 122 connected to the first rod body 121. The end of the first rod body 121 facing away from the second rod body 122 is connected to the dust-collecting component 11. The end of the second rod body 122 facing away from the first rod body 121 is used to abut against the bottom of the tin bath 100. The second rod body 122 can move relative to the first rod body 121 along the length direction of the first rod body 121 to adjust the distance between the end of the second rod body 122 facing away from the first rod body 121 and the dust-collecting component 11.

[0064] In this embodiment, the side of the dust-collecting component 11 facing the molten tin surface is spaced apart from the molten tin surface. This reduces the amount of molten tin entering the dust-collecting channel 111, thereby reducing molten tin loss. The positioning rod 12 is set as a telescopic rod, and its length can be adjusted by adjusting the telescopic amount of the positioning rod 12. This allows the positioning rod 12 to adapt to molten tin surfaces of different heights, ensuring that the distance between the dust-collecting component 11 and the molten tin surface is kept within a suitable range, thus guaranteeing the effective collection of molten tin dust.

[0065] In some embodiments, the distance L between the side of the dust-absorbing member 11 facing the molten tin surface and the molten tin surface can be 2mm to 3mm.

[0066] Continue to refer to Figure 8 In some embodiments, a first positioning hole may be provided at the end of the first rod 121, and a plurality of second positioning holes 1221 may be provided along the length of the second rod 122. When the second rod 122 slides relative to the first rod 121, the position between the plurality of second positioning holes 1221 and the first positioning hole can be adjusted so that the corresponding second positioning hole 1221 communicates with the first positioning hole. The positioning rod 12 may also include a pin 123, which can be inserted into the first positioning hole and the corresponding second positioning hole 1221 to lock the first rod 121 and the second rod 122, thereby fixing the length of the positioning rod 12.

[0067] In some embodiments, the housing 4 also includes a filter screen, which can be disposed inside the housing cavity. The filter screen can divide the housing cavity into a first chamber and a second chamber. The second chamber is located at the bottom of the first chamber and is connected to the dust suction pipe 21 through the first chamber.

[0068] It is understandable that when using the absorption component 1 to collect the tin ash floating on the surface of the molten tin, some of the molten tin may follow the tin ash into the suction pipe 21 and into the receiving cavity. A filter screen is installed in the receiving cavity. Under the filtering effect of the filter screen, the tin ash can be collected in the first chamber, while the molten tin flows into the first chamber under the action of gravity. In this way, the tin ash and molten tin can be separated, which helps to facilitate the subsequent cleaning of the tin ash.

[0069] In some embodiments, the housing 4 can be a storage bucket, storage box, etc.

[0070] In some embodiments, a flexible tube 3 can be provided at the end of the suction pipe 21 facing away from the suction channel 111, and the suction pipe 21 can be connected to the receiving cavity through the flexible tube 3. It is understood that during the tin ash collection operation, the suction pipe 21 can move to drive the suction component 11 to move, while the receiving component 4 can be placed on the ground or on a support frame; the flexible tube 3 is flexible and can be bent or stretched to change its shape, so that the relative position of the receiving component 4 and the suction pipe 21 can be easily adjusted, which facilitates the tin ash collection operation.

[0071] In some embodiments, the flexible tube 3 can be a rubber tube, a tubing, a corrugated tube, etc.

[0072] In some embodiments, the suction pipe 21 may be equipped with a first valve 213, which can be opened or closed to control the connection and disconnection between the receiving cavity and the suction channel 111, thus facilitating the operation. In other embodiments, the air inlet pipe 22 may be equipped with a second valve 221, which can be opened or closed to control the connection and disconnection between the air inlet pipe 22 and the suction pipe 21, thus facilitating the operation. In still other embodiments, the second valve 221 may be a flow valve, which can control the gas flow rate of the air inlet pipe 22, thereby controlling the gas flow rate in the suction pipe 21, and thus controlling the negative pressure value of the suction port 112, adjusting the suction force of the suction component 11.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
