Abstract
Description
Technical Field
[0001] The present application discloses the technical field of glass tube furnaces, and in particular, to a glass furnace device. Background Art
[0002] Medium borosilicate glass is an internationally recognized safe material for pharmaceutical glass packaging. It has the characteristics of low thermal expansion coefficient, good water resistance, high chemical stability and good toughness. The glass tubes, glass bottles and other containers made of it are mostly used to contain injections and blood preparations to ensure the purity of the liquid medicines contained, avoid reactions with the glass containers, cause drug contamination, and prevent the glass from falling off and forming visible foreign matter in the liquid medicines, which may cause blockage of capillaries when injected into the human body.
[0003] The production of medium-borosilicate pharmaceutical glass requires a high purity of the glass liquid, and the glass raw materials and kilns are often doped with impurities. The impurities precipitate to the bottom of the glass liquid and pollute the glass liquid, resulting in the glass tubes produced with the glass liquid doped with impurities failing to meet the pharmaceutical quality standards. Therefore, the glass liquid must be unloaded and impurity-removed. Conventional bottom-level unloading and impurity removal of the glass liquid is achieved by setting a unloading hole at the bottom of the kiln, and continuously unloading and discharging the glass liquid doped with impurities at the bottom through the unloading hole, so that the impurities in the bottom-level glass liquid are reduced and the purity is improved, so that the glass liquid in the kiln flows into the next process and is finally processed and formed. Since the total amount of glass liquid continues to decrease during the unloading process, it is inconsistent with the total amount of glass liquid parameters pre-entered in the subsequent production equipment, resulting in unstable glass tube molding, and the dimensional accuracy of the glass tube cannot be ensured, such as the dimensional tolerance of the glass tube wall thickness and the inner diameter parameters, so that the product cannot meet the standards and be put into use. To solve the above problem, materials are manually collected at the discharge hole using a receiving shovel within a unit of time, and then the collected discharge materials are transferred to a flat scale for weighing, the discharge flow parameters are obtained and the data is recorded, and then filling is performed according to the calculated discharge amount to make the total amount of glass liquid constant, thereby meeting the production process parameters and improving the product yield.
[0004] However, in the process of manual material measurement, due to the high temperature of the glass liquid flowing out of the discharge hole, the traditional manual measurement not only has safety hazards, but also the measurement operation method varies from person to person, and the accuracy of the measurement cannot be guaranteed, resulting in large errors in the measured data. As a result, the required amount of filler cannot be accurately calculated through the measured data, resulting in errors in the total amount of glass and the production process parameters, which ultimately leads to the inability to stably form the glass tube or large errors, thereby reducing the production yield.

[0033] like Figure 1 As shown, the glass furnace device includes a connecting bracket 20, a rotating arm 30, and a weighing assembly 40;
[0034] The connecting bracket 20 is fixedly arranged at the bottom of the kiln 00, and the connecting bracket 20 and the discharge hole 10 at the bottom of the kiln 00 are arranged at intervals;
[0035] A rotating arm 30, wherein a first end of the rotating arm 30 is horizontally rotatably connected to the connecting bracket 20, and a second end of the rotating arm 30 extends away from the connecting bracket 20; and,
[0036] A weighing assembly 40, the weighing assembly 40 is disposed at the second end of the rotating arm 30;
[0037] The longitudinal projection length of the rotating arm 30 is equal to the spacing distance between the connecting bracket 20 and the discharge hole 10 , and the rotating arm 30 can drive the weighing assembly 40 to reciprocate between the lower end of the discharge hole 10 and the position away from the lower end of the discharge hole 10 .
[0038] Specifically, the connecting bracket 20 is welded and fixed to the bottom of the glass furnace 00 and is integrally arranged, extending downward from the bottom. The connecting bracket 20 can be in the form of a truss, a hollow tube or a solid column. The other end of the connecting bracket 20 is connected to the rotating arm 30, and the connection method can be welding or flange connection. The rotating arm 30 can rotate horizontally with the connecting bracket 20 as the axis, so that the other end of the rotating arm 30 can rotate and extend to the bottom of the discharge hole 10, and the weighing component 40 arranged at the other end of the rotating arm 30 receives the discharge and weighs the discharge amount. The weighing component 40 can receive the glass liquid flowing out of the discharge hole 10 and weigh the received glass liquid.
[0039] The glass kiln device disclosed in the present application is provided with a connecting bracket 20 integrally arranged at the bottom of the kiln 00, and a rotating arm 30 capable of horizontal rotation is installed on the connecting bracket 20, and the longitudinal projection length of the rotating arm 30 is equal to the distance between the connecting bracket 20 and the discharge hole 10. The weighing assembly 40 assembled at the other end of the rotating arm 30 can reach the bottom of the discharge hole 10 to receive the material under the rotation drive of the rotating arm 30, and then weigh it, thereby replacing manual weighing. The glass kiln device is equipped with an automatic weighing device and adopts mechanized drive, which not only improves production safety, but also improves measurement accuracy, avoids the generation of measurement errors, and thus improves production quality.
[0040] In some embodiments, the weighing assembly 40 includes a receiving member 41 and a measuring member 42 . The measuring member 42 is connected to the second end of the rotating arm 30 . The receiving member 41 is fixedly disposed on one side of the measuring member 42 close to the bottom of the kiln 00 .
[0041] Specifically, the receiving part 41 of the weighing assembly 40 is used to receive the glass liquid flowing out of the discharge hole 10. It is in the shape of a groove, and the bottom has a certain depth. The side surrounds the outer edge of the bottom to form a storage space. Among them, an inclination angle is set between the side and the bottom, so that the side expands outward, which is convenient for pouring the measured glass liquid. The receiving part 41 is made of a material that does not react with high-temperature glass liquid, such as ceramic material. When the glass liquid falls into the receiving part 41 made of ceramic material, it will gradually cool and take shape, and will not stick to the receiving part 41, making it very convenient to pour the glass liquid after measurement.
[0042] The measuring member 42 includes a fixing seat and a measuring end, which is connected to the second end of the rotating arm 30 through the fixing seat, and can be detachably connected by welding or flange bolts. The measuring end is connected to the receiving member 41, and the weight borne is calculated through the deformation under load, so as to measure the discharge amount.
[0043] In some embodiments, the connecting bracket 20 is vertically arranged on the bottom wall of the kiln 00, and a first rotating unit 50 is arranged between the first end of the rotating arm 30 and the connecting bracket 20. The first rotating unit 50 can drive the second end of the rotating arm 30 to rotate horizontally around the connecting bracket 20 as the axis.
[0044] Specifically, the first rotating unit 50 is arranged between the rotating arm 30 and the connecting bracket 20. As a rotating connecting part, the first rotating unit 50 includes a rotating shaft, which is horizontally arranged and parallel to the bottom of the kiln 00, so that the rotating arm 30 can rotate and move horizontally, and make the other end of the rotating arm 30 approach or move away from the lower end of the discharge hole 10. When approaching and located at the lower end of the discharge hole 10, the receiving part 41 is used to receive the material, and stays for a period of time as set, and then moves away from the discharge hole 10. The glass liquid received by the receiving part 41 is weighed by the measuring part 42 to obtain the outflow amount of the glass liquid per unit time (KG / H).
[0045] In some embodiments, a second rotating unit 60 is disposed between the weighing assembly 40 and the rotating arm 30 , and the second rotating unit 60 drives the weighing assembly 40 to flip around the rotating arm 30 so that the measured waste received by the weighing assembly 40 is dumped out.
[0046] Specifically, the second rotating unit 60 is arranged between the weighing assembly 40 and the second end of the rotating arm 30. As a rotating connecting piece, the second rotating unit 60 includes a rotating shaft, which is longitudinally arranged relative to the bottom of the kiln 00 and can drive the weighing assembly 40 to flip relative to the bottom of the kiln 00 with the rotating arm 30 as the axis, and dump the measured glass liquid waste through the flipping action, thereby waiting for the next weighing cycle and re-taking weighing.
[0047] In some embodiments, the first rotating unit 50 is a rotating motor or a rotating cylinder, a fixed end of the first rotating unit 50 is connected to the connecting bracket 20 , and an output end of the first rotating unit 50 is connected to the first end of the rotating arm 30 .
[0048] In some embodiments, the second rotating unit 60 is a rotating motor or a rotating cylinder, a fixed end of the second rotating unit 60 is connected to the second end of the rotating arm 30 , and an output end of the second rotating unit 60 is connected to the weighing assembly 40 .
[0049] Specifically, the output end of the second rotating unit is fixedly connected to the fixing seat of the measuring member 42 so as not to affect the measurement of the measuring end, thereby ensuring the accuracy of the measurement.
[0050] In some embodiments, a transition section 31 is provided at one end of the rotating arm 30 close to the connecting bracket 20 , and an inclination angle is formed between the transition section 31 and the connecting bracket 20 .
[0051] Specifically, the provision of the transition section 31 can increase the connection stability between the rotating arm 30 and the connecting bracket 20, increase the overall structural strength of the rotating arm 30, make the rotating wall more stable during rotation, and extend the service life and prevent damage.
[0052] In some embodiments, the receiving member 41 includes a bottom and a side portion, the bottom is in close contact with the measuring member 42, and the side portion is fixedly disposed along the outer circumference of the bottom.
[0053] Specifically, the bottom has a certain depth, and the side surrounds the outer edge of the bottom to form a containing space. An inclination angle is provided between the side and the bottom, so that the side expands outwards to facilitate pouring of the measured glass liquid.
[0054] In some embodiments, the measuring member 42 is a weight sensor.
[0055] Specifically, the weight sensor is any one of pneumatic, hydraulic, strain gauge, and capacitive. Among them, the strain gauge or capacitive type can improve the measurement accuracy.
[0056] In some embodiments, a control unit 70 is further included, and the rotating arm 30 and the weighing assembly 40 are both electrically connected to the control unit 70 .
[0057] Specifically, the control unit 70 is connected to the rotating arm 30 and the weighing assembly 40 through a signal cable, and can teach the operating position of the rotating arm 30, determine the waiting position, the material receiving position, that is, below the discharge hole 10, and the weighing and unloading position. The control unit 70 can set the material receiving and weighing cycle, and set the material receiving time. For example, the material is received every few hours or minutes, and the material is received within the set time.
[0058] Complete weighing cycle:
[0059] When the preset interval weighing time is reached, the rotating arm 30 starts to run from the waiting position, reaches the material receiving position, and receives the material according to the set material receiving time. After completing the material receiving action, the rotating arm 30 rotates horizontally to the weighing and unloading position, away from the continuously flowing glass liquid, and uses the weighing component 40 to accurately weigh. After obtaining the data, the data is fed back to the control unit 70, and then the second rotating unit 60 drives the weighing component 40 to flip, and dumps the measured waste into the waste hopper. Then the rotating arm 30 resets to the waiting position and waits for the next weighing cycle.
[0060] The control unit 70 converts the data collected by the weighing component 40 into the discharge amount KG / H, forming process parameters for the staff to obtain and know the amount of material to be added.
[0061] The glass kiln device of the present application can safely and accurately obtain the discharge volume data, which greatly contributes to the improvement of product production quality.
