Description

Technical Field

[0001] The present invention relates to a fire-blocking device for a glass production line, and in particular to a fire-blocking device for a glass production line applied in the field of glass production. Background Art

[0002] The main function of the fire damper for glass production line is to prevent flames and heat from being transmitted through various parts of the kiln, protecting the safety of equipment and operators. In addition, the fire damper has another function. Due to impurities in the raw material melting process of the glass production line, the glass surface is polluted during the flow of gas, affecting the gloss of the glass and reducing the grade of the glass. The fire damper is easily deformed due to the long-term high temperature during use. In order to solve the problem of heat deformation of fire dampers, a certain fire damper equipment on the market adopts a cooling water circulation design and has a certain market share.

[0003] The Chinese patent CN201820619702.1 specification discloses an annealing furnace entrance baffle, which drives the baffle door to rise or fall through a control mechanism to keep the interior of the annealing furnace warm, reduce the use of electric heating, reduce energy consumption and reduce costs. At the same time, it ensures that the original working conditions are maintained when production resumes, greatly reducing the time for secondary debugging; after using a cooler, the heat absorbed by the baffle door at the entrance of the annealing furnace can be discharged through the cooling water chamber to prevent the baffle door from deforming due to excessive temperature, thereby improving the production quality of glass.

[0004] The specification of Chinese patent CN201110143460.6 discloses a curtain at the entrance of an annealing furnace in a float glass production line, the curtain comprising a baffle and a suspension rod, the baffle and the suspension rod are connected by a shell, a water cooling chamber is arranged inside the shell, a water inlet pipe and a water outlet pipe are arranged on the shell, and the water inlet pipe and the water outlet pipe are both connected to the water cooling chamber. The advantage of the present invention is that after adopting the cooling device, the heat absorbed by the curtain at the entrance of the annealing furnace can be discharged by cooling water, so as to prevent the baffle from being deformed due to excessive temperature, thereby improving the production quality of glass.

[0005] Existing fire dampers all use cooling water to take away heat, but the required cooling water flow rate is different during the rising and falling process of the fire damper. For example, after the fire damper rises, its heated area increases, so the flow rate needs to be increased, and after the fire damper falls, the heated area decreases, so the flow rate needs to be reduced. This can effectively reduce the cooling water processing burden and reduce energy consumption. However, it is obvious that most of the existing fire dampers do not have this adjustment function. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to adaptively adjust the flow rate of cooling water according to the raising and lowering of the fire baffle.

[0007] In order to solve the above problems, the present invention provides a fire blocking device for a glass production line, comprising a temperature sensor and a gas concentration monitoring sensor installed on the production line and two columns, and the side walls of the two columns are provided with slide grooves, the bottoms of the two columns are provided with lead screw lifts, and the lead screw lifts are connected to drive motors matched therewith, the temperature sensor and the gas sensor are electrically connected to the drive motors through a control processor, the output end of the lead screw lift is connected to a lifting rod, and the lifting rod is fixedly connected to a horizontal lower cooling water rack, and the upper end of the lower cooling water rack is provided with a guide rod, and the guide rod ... An upper cooling water rack is fixedly connected to the end, and cooling water flow channels are provided inside the lower cooling water rack and the upper cooling water rack. A slot is provided on the upper end side wall of the upper cooling water rack, and a plurality of side-by-side fire baffles are inserted in the slot. The fire baffles are connected to the upper cooling water rack by bolts. One end of the lower cooling water rack and the upper cooling water rack are respectively connected to a cooling water inlet joint and a cooling water return joint connected to the cooling water flow channel. A cooling water tank is provided on one side of the column, and a water outlet pipe and a water inlet pipe connected to the cooling water inlet joint and the cooling water return joint are connected to the cooling water tank.

[0008] In the fire damper equipment for the above-mentioned glass production line, temperature sensors and gas concentration monitoring sensors are used to monitor the ambient temperature and gas concentration of the production line in real time, so as to adjust the lifting and lowering of the fire damper, and utilize the lifting and lowering of the fire damper to adaptively regulate the flow of cooling water.

[0009] As a further improvement of the present application, a measuring box is fixedly connected to the upper ends of the two columns, and the lower end of the measuring box is slidably connected to a vertical pole fixedly connected to the upper cooling water rack, and an adaptive flow regulator is connected to the water outlet pipe. The measuring box includes a current signal amplification module and a control module, and the control module is electrically connected to the adaptive flow regulator through a control processor. The fire baffle will drive the vertical pole to rise and fall inside the measuring box during the lifting process, and the current measured by the measuring box will change during the movement of the vertical pole. The current signal amplification module will amplify the measured current, and control the adaptive flow regulator through the control module to adjust the circulation volume of the cooling water, thereby adaptively adjusting according to the working state of the fire baffle, effectively saving energy consumption and reducing the heat dissipation burden of the cooling water.

[0010] As a further improvement of the present application, the measuring box includes a high temperature resistant box body, a current measuring device electrically connected to the current signal amplification module is installed at the upper end of the vertical pole, and the end of the current measuring device away from the vertical pole is fixedly connected to a conductive rod, the inner wall of the high temperature resistant box body is fixedly connected to a vertically placed resistor bar, and the conductive rod is in contact with the resistor bar, the bottom end of the resistor bar is set to point a, and the contact point between the conductive rod and the resistor bar is set to point b. The current measuring device is used to measure the current from point b to point a. When the vertical pole rises, the resistance between point b and point a increases. At this time, the current measured by the current measuring device will become smaller. After this current signal is amplified by the current signal amplification module, the current of the electromagnet is reduced through the control module, thereby reducing the magnetic force generated by the electromagnet, thereby increasing the circulation of cooling water. Conversely, when the vertical pole descends, the resistance between point b and point a decreases. At this time, the current measured by the current measuring device will increase, thereby increasing the magnetic force generated by the electromagnet and reducing the circulation of cooling water.

[0011] As a further improvement of the present application, the adaptive flow regulator includes a seat body, and an installation groove is provided on the inner wall of the seat body, a deformable flow tube is fixedly connected to the middle of the installation groove, and the deformable flow tube is connected to the water outlet pipe, electromagnets are installed on the inner walls on both sides of the installation groove, and the electromagnets are electrically connected to the control module, and flow regulating clamps are slidably connected to the inner walls on both sides of the installation groove, which are against the deformable flow tube, and the flow regulating clamps and the magnetism generated by the electromagnets repel each other, and a plurality of symmetrically distributed restraining parts are fixedly connected between the flow regulating clamps and the inner wall of the installation groove, when the current measured by the current measuring device decreases, the control module will reduce the current of the electromagnet, thereby reducing the magnetic force of the electromagnet to increase the cooling water circulation, and when the current measured by the current measuring device increases, the control module will increase the current of the electromagnet, thereby increasing the magnetic force of the electromagnet to reduce the cooling water circulation, and the electromagnet uses the magnetic repulsion force on the flow regulating clamp to clamp the deformable flow tube to control the cooling water circulation.

[0012] As another improvement of the present application, the deformable circulation tube includes two hard tube bodies fixedly connected to the inner wall of the mounting groove, and an elastic tube body is fixedly connected between the two hard tube bodies. The cooling water flows through the deformable circulation tube during the circulation process, and the hard tube body plays a shaping role. The elastic tube body can be deformed under the extrusion of the flow regulating chuck, thereby changing the cross-sectional area and thus changing the circulation amount of the cooling water.

[0013] As another improvement of the present application, the restraining member includes an elastic bag shell, the inner wall of which is fixedly connected with two groups of symmetrically distributed inelastic stretching rods, and an elastic stretching bag is fixedly connected between each group of two inelastic stretching rods. The restraining member serves to reset the flow regulating chuck, and cooperates with the magnetic repulsion force of the electromagnet to regulate the flow rate of the deformable flow tube. In this process, the elastic bag shell and the elastic stretching bag rely on their own elastic force to restrain the flow regulating chuck.

[0014] To summarize, by adding temperature sensors and gas concentration sensors to the existing glass production line to monitor the ambient temperature and gas concentration, the lifting of the fire baffle is controlled to achieve the purpose of real-time adjustment according to the production situation, and the lifting of the fire baffle is used to measure the current, and the electromagnetic force is adjusted according to the current, thereby adjusting the circulation of cooling water. In this way, the supply of cooling water can be adaptively adjusted according to the size of the heated area of ​​the fire baffle, which can not only effectively reduce the workload of processing cooling water, but also effectively save energy. In addition, the structure of the entire adaptive adjustment device is stable and the failure rate is low, which can effectively extend the service life of the fire baffle.
