Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of glass production field process monitoring, specifically relates to a kind of detection device of continuously obtaining glass liquid flow. BACKGROUND

[0002] In the glass production process, the feeding amount and the discharging amount of the glass furnace are balanced, which is an important prerequisite for stable production. If the discharging amount is too high or too low, it will be out of balance with the feeding amount, causing fluctuations in the internal temperature and liquid level of the furnace, thereby affecting the stability of production. Therefore, after adjusting the production temperature, replacing the forming equipment, and the furnace discharge, etc., the flow data of the glass furnace discharge or discharge is needed to be obtained, so as to adjust the feeding amount and other process parameters correspondingly, and ensure the stability of production.

[0003] At present, to obtain the flow data of the glass furnace discharge or discharge, generally, a person uses a measuring spoon or other tools to intermittently collect the glass liquid flowing out of the furnace for a period of time, and then calculates the glass liquid flow by weighing. This method not only has a long interval time for measurement, but also is difficult to obtain instantaneous flow and adjust the process parameters in time. Moreover, the operation process is difficult to control and form effective flow data, which may lead to large measurement errors. In addition, manual operation has a high safety risk. There are also mechanical devices to assist in measurement, such as the overflow glass flow measuring device for medicinal glass furnace disclosed in Chinese patent CN113984130B. This scheme adds a driving structure between the measuring spoon and the weighing device to drive the horizontal movement and rotation of the measuring spoon, replacing the manual operation of the measuring spoon to complete the action process of receiving, weighing and pouring. Mechanical operation not only can achieve better control and form effective flow data through program setting, thereby reducing measurement errors, but also is safer than manual operation. Although the measurement interval time can be shortened to improve the timeliness of measurement, the process of receiving, weighing and pouring itself needs a certain time, so the measured flow is still difficult to approach the instantaneous flow, and the flow cannot be continuously output, which still has the defect of poor timeliness.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0028] Embodiment:

[0029] Please refer to Figure 1 and Figure 4 A detection device for continuously obtaining the glass liquid flow rate, comprising a material receiving container 1 with an opening facing upward, a material guide pipe 2 arranged above the material receiving container 1, an inlet end 3 of the material guide pipe 2 for receiving the discharge of a kiln, and an outlet end 4 facing and close to the opening of the material receiving container 1 for guiding the discharge of the kiln into the material receiving container 1, a weighing device 5 arranged below the material receiving container 1 for obtaining the weight of the material in the material receiving container 1, and a control processor electrically connected with the weighing device 5 for calculating the discharge flow rate of the kiln according to the weight change of the material.

[0030] The utility model discloses a detection device of continuous acquisition glass liquid flow, when using, the detection device is placed below glass kiln, the import end 3 of material guide pipe 2 is communicated with the leakage or the discharge of kiln, and the glass liquid that kiln flows is continuously introduced into the receiving container 1, and the weight of the glass liquid in receiving container 1 is measured in real time by weighing equipment 5, and the weight value is transmitted to control processor, and the weight value increment corresponding to a period of time and corresponding time are calculated according to control processor, and the weight value increment corresponding to unit time is calculated, and the discharge flow of kiln in unit time is calculated in combination with the preset glass liquid density value, which can not only continuously output the discharge flow, but also can obtain the discharge flow close to instantaneous by shortening the time corresponding to the weight value increment, thereby improving the timeliness of measurement, so as to adjust the process parameter in time, and reduce the debugging time consumption.

[0031] Because the heat of glass liquid is transferred to weighing equipment 5 through receiving container 1 during measurement, the weighing equipment 5 is easily damaged due to the high temperature of glass liquid, in addition, the glass liquid is easily adhered to receiving container 1 during cooling and solidification in receiving container 1, so that the receiving container 1 is difficult to clean. Figure 1 and Figure 4 As shown in the utility model, a cooling water pipe 6 is arranged in communication with the material guide pipe 2, a flow meter 7 is arranged on the cooling water pipe 6, and the flow meter 7 is electrically connected with the control processor, so that the cooling water is introduced into the material guide pipe 2 through the cooling water pipe 6 during measurement, the cooling water is mixed with the glass liquid in the material guide pipe 2, the glass liquid is rapidly cooled and solidified into broken glass, and then the cooling water and the glass liquid continuously fall into the receiving container 1, which can not only avoid the high temperature of the receiving container 1 and the weighing equipment 5, but also avoid the adhesion of the glass liquid to the receiving container 1, so that the receiving container 1 is convenient to clean after measurement for next use, the flow data of the cooling water is transmitted to the control processor through the flow meter 7 arranged on the cooling water pipe 6, and the control processor calculates and removes the increment of the cooling water in the receiving container 1 according to the flow data of the cooling water and the preset density of the cooling water, so as to avoid the influence of the cooling water on the measurement of the discharge flow.

[0032] As shown in the utility model, Figure 1 The communication part of the cooling water pipe 6 and the material guide pipe 2 is close to the import end 3, so that the cooling water is mixed with the glass liquid in the material guide pipe 2 as soon as possible, the contact time of the glass liquid with the cooling water before entering the receiving container 1 is prolonged, and the glass liquid is fully cooled and solidified into broken glass when entering the receiving container 1.

[0033] As shown in the utility model, Figure 1, the guide pipe 2 is divided into an inlet section 24, a mixing section 25 and an outlet section 26 from top to bottom, the mixing section 25 is arranged obliquely, and the inlet section 24 and the outlet section 26 are arranged vertically and the free ends thereof are respectively the inlet end 3 and the outlet end 4; in this way, the oblique arrangement prolongs the length of the guide pipe 2 at the same vertical distance, which is beneficial to further prolong the contact time of the glass liquid with the cooling water before entering the receiving container 1, and ensures that the glass liquid is sufficiently cooled and solidified into glass cullet when entering the receiving container 1.

[0034] Please refer to Figure 1 , in the vertical direction, the projection of the inlet end 3 is located outside the projections of the receiving container 1 and the weighing device 5; in this way, in use, the kiln discharge port or the discharge port connected with the inlet end 3 is laterally offset from the receiving container 1 and the weighing device 5, so as to avoid that the glass liquid directly pours on the receiving container 1 and the weighing device 5 due to accidental falling of the guide pipe 2, which causes damage to the equipment or safety accidents due to splashing of the glass liquid.

[0035] Please refer to Figure 1 , in the vertical direction, the projection of the outlet end 4 is located in the center of the projection of the receiving container 1; in this way, in use, the glass cullet falls into the central area of the receiving container 1 from the outlet end 4 with the cooling water, and the glass cullet will accumulate in a conical shape below the outlet end 4, and as the accumulation height increases, the glass cullet at the bottom will also gradually spread to the periphery, since the glass cullet accumulates in the central area of the receiving container 1 and is away from the side wall of the receiving container 1, it will not block the spread of the glass cullet to the periphery, which not only helps to reduce the accumulation height of the glass cullet directly below the outlet end 4, avoids the abutment of the glass cullet with the outlet end 4, and thus affects the measurement, and also avoids that the weight of the glass cullet in the receiving container 1 is biased to one side or one corner, which affects the accuracy of the weighing of the weighing device 5.

[0036] Since the glass liquid is cooled and solidified into glass cullet with the cooling water in the guide pipe 2, the glass cullet is easy to accumulate below the outlet end 4 after falling into the receiving container 1 from the outlet end 4, and when the glass cullet accumulates to abut the outlet end 4, it will not only affect the weighing, but also cause the subsequent glass cullet to be unable to smoothly discharge; if the receiving container 1 is placed at a position with a large vertical distance from the outlet end 4, the falling glass cullet will cause a large impact on the receiving container 1, which will affect the accuracy of the measurement; therefore, as Figure 1As shown, the utility model discloses a support frame 8 is equipped with below weighing equipment 5, and the vertical lifting mechanism 9 is connected between weighing equipment 5 and support frame 8, and the vertical lifting mechanism 9 is electrically connected with control processor, and control processor is used for according to the discharge flow control vertical lifting mechanism 9 drive weighing equipment 5 and the container 1 of receiving material drop when detecting, and this, in use, the vertical lifting mechanism 9 drive weighing equipment 5 and the container 1 of receiving material gradually move downwards, make the highest place of material in the container 1 of receiving material always keep a certain distance with the outlet end 4, specifically, the discharge flow of measurement can be set as the parameter of control processor control vertical lifting mechanism 9 action, thereby dynamically adjust the speed of weighing equipment 5 and the container 1 of receiving material vertical movement, make the highest place of material in the container 1 of receiving material always keep close distance with the outlet end 4, to reduce the impact of broken glass falling on the container 1 of receiving material under the condition of not affecting weighing and broken glass discharge, improve the accuracy and stability of measurement.

[0037] Please refer to Figure 1 and Figure 4 , the lifting mechanism includes the lead screw 10 that sets up vertically, the screw rod 11 upper end of lead screw 10 is rotatably connected with the supporting plate 12, and weighing equipment 5 is arranged on the supporting plate 12, and the nut 13 of lead screw 10 is fixedly connected with support frame 8, and the first motor 14 of transmission connection is equipped on support frame 8 with screw rod 11, and the first motor 14 is electrically connected with control processor, and the guide rod 15 is vertically slidably connected on support frame 8, and the guide rod 15 upper end is connected with supporting plate 12, and thus, in use, control processor controls the first motor 14 drive screw rod 11 of lead screw 10 rotation, and the nut 13 of lead screw 10 is fixedly connected with support frame 8, so that screw rod 11 moves vertically along with rotation, thereby drive supporting plate 12 vertical movement, and when implementing, the vertical lifting mechanism 9 can also adopt the structure form such as electric push rod, hydraulic cylinder, and the embodiment adopts lead screw 10, compared with drive supporting plate 12 vertical movement through electric push rod and hydraulic cylinder, is more stable, accurate.

[0038] Please refer to Figure 1 、 Figure 2 and Figure 4 , one side of the container 1 of receiving material is equipped with container replacement mechanism 16, and container replacement mechanism 16 includes the rotating rod 18 that sets up vertically and is driven through the second motor 17, and the second motor 17 is electrically connected with control processor, and the rotating rod 18 is synchronously rotatably connected with rotating support 19, and rotating support 19 has multiple U-shaped brackets 20 that are evenly distributed around rotating rod 18, and one U-shaped bracket 20 corresponds with the container 1 of receiving material on weighing equipment 5, and every U-shaped bracket 20 is provided with the container 1 of receiving material for replacement respectively on the rest, and specifically, the container 1 of receiving material is located inside corresponding U-shaped bracket 20, please refer to Figure 1 and Figure 3The opposite sides of the receiving container 1 are respectively provided with support ears 21, and the U-shaped bracket 20 vertically penetrates and opens towards the circumferential outside. The U-shaped bracket 20 supports the inside receiving container 1 by abutting the support ears 21 with the upper end face of the U-shaped bracket 20. When assembling, it should be ensured that the support ears 21 of the receiving container 1 abut the upper end face of the U-shaped bracket 20 when the receiving container 1 is lowered to the lowest position by the lifting mechanism, and it should be ensured that the U-shaped bracket 20 has a vertical distance from the weighing device 5 when the receiving container 1 is raised to the highest position by the lifting mechanism, so as to avoid the influence of the U-shaped bracket 20 on the measurement;

[0039] In this way, during the measurement process, when the receiving container 1 is lowered to the lowest position by the lifting mechanism, the second motor 17 is controlled by the control processor to drive the rotating rod 18 to rotate by a certain angle, so that the U-shaped bracket on the rotating bracket 19 pushes the receiving container 1 containing the material away from the weighing device 5, and the replacement receiving container 1 is placed on the weighing device 5 by rotating the rotating rod 18, and then the lifting mechanism is controlled to rise and drive the receiving container 1 to reset. The detection device can be suitable for the working condition of long-time monitoring of the discharge flow of the kiln. During the replacement of the receiving container 1, the measurement should be paused or the measurement result should be paused, and the receiving container 1 is replaced by using the machine. The operation is standard and the time consumption can be shortened, which is beneficial to reduce the influence of the replacement of the receiving container 1 on the whole measurement. In the embodiment, the U-shaped bracket has four, and the rotating rod 18 rotates by 90 degrees when the receiving container 1 is replaced.

[0040] Please refer to Figure 1 and Figure 4 The micro switch 22 is connected below the supporting plate 12, and the trigger rod 23 is vertically arranged on the supporting frame 8. The trigger rod 23 has two protruding parts on the side surface for triggering the micro switch 22. The two protruding parts are vertically spaced and correspond to the lowest position and the highest position respectively. The micro switch 22 is electrically connected with the control processor, so as to control the first motor 14 to switch the rotation direction and the second motor 17 to start and stop through the limit switch;

[0041] In this way, after starting the measurement, the control processor controls the first motor 14 to rotate in the forward direction to drive the screw rod 11 to rotate and descend, so that the weighing device 5 and the receiving container 1 gradually move downward, and the highest position of the material in the receiving container 1 is always kept at a certain distance from the outlet end 4. When the receiving container 1 descends to the lowest position, the switch spring of the micro switch 22 is deformed by being pressed by the corresponding protruding part. The deformation of the switch spring makes the circuit of the micro switch 22 conductive, that is, the micro switch 22 is triggered, so that the control processor controls the first motor 14 to stop, and controls the second motor 17 to drive the rotating rod 18 to rotate to replace the receiving container 1. The control processor is preset with the time required for replacing the receiving container 1. After the receiving container 1 is replaced, the control processor controls the first motor 14 to rotate in the reverse direction to drive the screw rod 11 to rotate and ascend, so that the weighing device 5 and the receiving container 1 move upward. When the receiving container 1 ascends to the highest position, the micro switch 22 is pressed and triggered by the corresponding protruding part, so that the control processor controls the first motor 14 to rotate in the forward direction to drive the screw rod 11 to rotate and descend, so as to perform the next stage of measurement. By arranging the trigger rod 23 for triggering the micro switch, the detection device can automatically complete the action process of replacing the receiving container 1 and resetting the receiving container 1 for continuous measurement. The detection device is more in line with the development of automatic production, and is conducive to reducing the labor intensity and improving the production efficiency.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit the technical solutions. Those skilled in the art should understand that those who modify or equivalently replace the technical solutions of the present application without departing from the spirit and scope of the present application should be covered in the scope of the claims of the present application.
