Description

Technical Field

[0001] This invention belongs to the field of refractory production equipment, specifically relating to an automated filling and coating equipment for refractory glaze used in steel brick casting. Background Technology

[0002] Castable steel bricks are hollow cylindrical refractory bricks. The central through-hole is primarily used for casting molten steel or iron. The high-temperature molten steel needs to flow through this central through-hole, and the central through-hole is easily penetrated and damaged due to long-term erosion from the high-temperature molten steel, thus reducing the service life of the castable steel brick. During the manufacturing process, to improve the high-temperature resistance of castable steel bricks, a layer of refractory glaze is coated onto the inner wall of the brick, enhancing its high-temperature resistance and erosion resistance. In the prior art, equipment for coating the inner surface of steel bricks with refractory glaze, such as the patent with authorization publication number "CN207839327U" and titled "A Coating Device for Steel Bricks," discloses placing the steel brick on a turntable, rotating the turntable to the operating position via a motor, manually pouring refractory glaze into the central through-hole of the steel brick, and draining excess refractory glaze from the central through-hole through a electrically controlled valve after a period of soaking. While this device can solve the problem of coating the inner wall of the central through-hole of steel bricks with refractory glaze, its automation level is low, requiring multiple operators to complete the coating operation.

[0003] The main technical problems with the coating device for the inner wall of the central through-hole of the cast steel brick disclosed in the aforementioned patent are as follows: 1. When manually pouring refractory glaze, the liquid level of the refractory glaze at the top of the central through-hole of the cast steel brick cannot be precisely controlled, easily causing the refractory glaze to overflow from the central through-hole and coat the upper end face or circumferential outer wall of the angle steel brick. This affects the aesthetic appearance of the angle steel brick and, during the laying or pouring of the cast steel brick, the refractory glaze coating on the end face or circumferential outer surface of the cast steel brick affects the bonding strength of the refractory mortar or castable. 2. When manually pouring refractory glaze, some spillage is inevitable, resulting in a significant waste of the refractory glaze coating material. Based on the above-mentioned defects in the existing technology, there is an urgent need for an automated filling and coating device for refractory glaze for cast steel bricks to solve these problems. Summary of the Invention

This section describes the internal structure of the laser positioning and feeding device 108 itself. The liquid level controller moves the cast steel brick 4 placed above its through hole to directly below the feed pipe by rotating the circular disc. At the same time, the lower end of the bracket is adjusted.

In actual operation, the glaze liquid flowing from the lower end of the feed pipe is poured into the inner hole in the middle of the steel casting brick 4. Simultaneously, the two sensors alternately emit infrared lasers 10843. The infrared laser 10843 emitted by sensor 10841, aligned with the inner hole in the middle of the steel casting brick 4, strikes the surface of the glaze liquid poured into the inner hole and is reflected, received by sensor 10841, recorded as data, and transmitted to the PLC industrial control module. The infrared laser 10843 emitted by sensor 10842, which is aimed at the upper end face of the side wall of the steel brick 4, hits the upper end face of the side wall of the steel brick 4 and is reflected by sensor 10842. It records a data and transmits it to the PLC industrial control module. When the two data are approximately the same (the difference range between the two data can be set, and when the two data reach this difference range, they are considered to be approximately the same), the PLC industrial control module will control the pneumatic valve 3 to close the feeding pipe so that the glaze liquid stops flowing out from the lower end of the feeding pipe. At this time, the servo motor at the lower end of the circular plate rotates again under the control of the PLC industrial control module, so that the next steel brick 4 placed above the through hole at the upper end of the circular plate is moved to the lower end of the feeding pipe directly below the pipe opening.

This section mainly describes the specific shape of the material feeding funnel 119 and its connection relationship with the cuboid frame 103, as well as the connection between the material feeding funnel 119 and pipe 115.

[0028] The circular disk 116 has a circular metal protrusion at the lower edge of its edge. The axis of the circular metal protrusion at the lower edge of the circular disk 116 is coplanar with the axis of a through hole 117 on the circular disk 116 and the axis of the circular disk 116 itself. In the cuboid frame 103, the upper end of the front support square tube in the third square support frame from the top is equipped with a U-shaped bracket 1085. The U-shaped bracket 1085 is in the shape of an inverted U. The two legs of the U-shaped bracket 1085 are fixedly connected to the upper end face of the support square tube. A touch sensor is installed in the middle of the upper end of the U-shaped bracket 1085. The circular metal protrusion corresponds to the touch sensor in the vertical direction. The touch sensor is connected to the PLC industrial control module in the servo control box 2 via a data cable. A rubber pad is applied around the edge of the through hole 117 on the upper end face of the circular disk 116. The rubber pad is square in shape. This section mainly describes the vertical relationship between a circular metal protrusion at the lower edge of the circular disk 116 and a touch sensor installed at the upper center of the U-shaped bracket 1085. In fact, when the circular disk 116 rotates along its center under the drive of the servo motor 120, the lower end of the circular metal protrusion at the lower edge of the circular disk 116 will inevitably strike the upper end of the touch sensor. At this time, the touch sensor quickly sends a signal to the PLC industrial control module in the servo control box 2. The PLC industrial control module quickly instructs the servo motor 120 to stop operating, thereby stopping the circular disk 116 from rotating. Since the axis of the circular metal protrusion at the lower end of the circular disk 116, the axis of a through hole 117 on the circular disk 116, and the axis of the circular disk 116 are all coplanar, the PLC industrial control module quickly completes the coordinate positioning and coordinate correction of the through hole 117 in the circular disk 116.

[0029] The storage funnel 102 itself has a discharge port on the upper left side of its barrel-shaped shell. One end of the pipe 105 is connected to the discharge port, and the other end of the pipe 105 is connected to the upper left side of the glaze liquid storage tank 110. The purpose of this arrangement is to prevent the glaze liquid in the storage funnel 102 from flowing back into the glaze liquid storage tank 110 through the pipe 105 when the glaze liquid level is too high in the event of a malfunction of the ultrasonic level detector.

[0030] The working steps of the automated filling and coating equipment for lining glaze of steel bricks according to the present invention are as follows:

[0031] First, before starting the work, fill the water storage tank 112 with water and the glaze liquid storage tank 110 with refractory glaze liquid; turn on the power through the servo control box 2, and power on the main filling and coating equipment 1, the air pump or the workshop high-pressure gas pipeline 3, and the servo control box 2; place the cast steel brick 4 or the sprue brick or the steel pipe brick or the same type of brick on the rubber pad on the edge of the circular plate 116, with the center line of the hollow cavity contained in the cast steel brick 4 or the sprue brick collinear with the center line of the through hole 117 on the edge of the circular plate 116.

[0032] The second step is to turn on the working button of the servo control box 2. The PLC industrial control module inside the servo control box 2 works according to the working program. Under the control of the PLC industrial control module, a hollow tube of a steel casting brick 4 or a similar brick type, such as a water nozzle brick, on the upper end of the circular disc 116 is aligned with the lower end of the discharge pipe 1083 of the laser positioning and feeding device 108 above it in the vertical direction. The PLC industrial control module controls the pneumatic solenoid valve controller 123 through the data cable to close the pneumatic valve 124 on the right side of the pipe 114 and open the pneumatic valve 124 on the left side.Simultaneously, the PLC industrial control module starts the glaze pump device 111 through the power management module. Glaze liquid in the left-side glaze storage tank 110 enters the glaze pump device 111 through pipes 114 and 125. Under the pressure of the impeller rotation within the glaze pump, the glaze liquid flows through pipe 104 (connected to the upper pipe opening of the glaze pump) and the side inlet of the storage funnel 102 into the storage funnel 102. The glaze liquid can be temporarily stored in the storage funnel 102. (When the glaze liquid reaches a certain height in the storage funnel 102 and is detected by the ultrasonic level detector 101 located above the storage funnel 102, the ultrasonic level detector will quickly send a signal to the PLC industrial control module.) The module quickly shuts down the sand pump device via the power management module, thereby stopping the glaze liquid from entering the storage funnel 102 through pipe 104. Conversely, when the glaze liquid level in the storage funnel 102 is insufficient, the ultrasonic level detector 101 sends a signal to the PLC industrial control module to prompt the start of the glaze pump device 111 (to add glaze liquid into the storage funnel 102). The glaze liquid then quickly flows out from the lower opening of the storage funnel 102 and falls through pipe 106 and discharge pipe 1083 into the hollow cavity inside the cast steel brick 4 or similar brick type, quickly filling it. At the same time, the laser level detector itself measures the height of the glaze liquid level in the hollow cavity of the cast steel brick 4 or similar brick type. When the glaze liquid level reaches the required height, the level controller will quickly send a signal to the PLC industrial control module via the data line. After receiving the signal, the PLC industrial control module will control the pneumatic valve 1081 through the pneumatic solenoid valve controller 123 to close the flow in the discharge pipe 1083. The glaze liquid in the storage funnel 102 will stop flowing through its lower opening, pipe 106, discharge pipe 1083 and into the hollow cavity of the cast steel brick 4 or sprue brick, etc. After a few seconds, the PLC industrial control module will control the circular disk 116 to rotate itself to a fixed angle through the servo motor 120 at the lower end of the circular disk 116. Another cast steel brick 4 or sprue brick of the same type on the circular disk 116 will then rotate with the circular disk 116. 16. Rotate and move to directly below the laser measuring and feeding device 108, aligning the upper end of the hollow cavity of the brick with the lower opening of the feeding pipe 1083 of the laser measuring and feeding device 108 in the vertical direction. Simultaneously, the liquid level controller of the laser measuring and feeding device determines that the hollow cavity of the brick 4 or sprue brick is empty by laser measurement and quickly sends a signal to the PLC industrial control module. Upon receiving the signal, the PLC industrial control module controls the pneumatic valve 1081 through the pneumatic solenoid valve controller 123 to open the pipe in the feeding pipe 1083 for flow. The glaze liquid in the storage funnel 102 re-enters the hollow cavity of the brick 4 or sprue brick through its lower opening, pipe 106, and feeding pipe 1083, and then flows back into the hollow cavity of the brick 4 or sprue brick, and so on.

[0033] Thirdly, as the circular disc 116 rotates repeatedly to a fixed angle, the steel-cast bricks 4 or sprue bricks, whose hollow cavities are filled with glaze liquid, pass sequentially above the discharge funnel 119 as the disc 116 rotates. At this time, the PLC industrial control module controls the pneumatic solenoid valve controller 123 via the data cable to close the pneumatic valve 124 on the right side of the pipe 113. The PLC industrial control module will accurately calculate and control the pneumatic valve 124 located directly above the discharge funnel 119 to open. The pneumatic valve 124 is installed below each through hole 117 of the circular disc 116, and the through hole 117 is aligned with the hollow cavity of the steel-cast brick 4 or sprue brick. As the pneumatic valve 124 opens, the glaze liquid in the hollow cavity of the steel-cast brick 4 or sprue brick flows completely into the lower circular disc 116 through the through hole 117 and the pneumatic valve 124. In the material funnel 119, after a few seconds, the pneumatic valve 124 closes. As the circular disc 116 automatically rotates to a fixed angle, the next steel brick 4 or sprue brick is positioned above the material funnel 119 again as the circular disc 116 rotates, and the above process is repeated. The glaze liquid falling into the material funnel 119 flows back into the glaze liquid storage tank 110 through the lower opening of the material funnel 119, pipe 115, and pipe 113. The steel brick 4 or sprue brick that has completed the filling, coating, and impregnation of the hollow cavity is unloaded from the circular disc 116 by the operator or the robotic arm. New steel brick 4 or sprue brick of the same type that has not undergone filling, coating, or impregnation is placed on the circular disc 116, and the center line of the hollow cavity of the steel brick 4 or sprue brick of the same type must be collinear with the center line of the through hole 117 on the circular disc 116.

[0034] The fourth step involves cleaning the main filling and coating equipment 1 and its pipelines with clean water after all the hollow tubes of the cast steel bricks 4 or similar bricks have undergone glaze liquid filling, coating, and impregnation. The main working steps are as follows: A plastic cleaning bucket with openings at both the top and bottom is placed above each through hole 117 on the upper end of the circular disc 116. The lower end of the plastic cleaning bucket is positioned above the rubber pad, and the axis of the plastic cleaning bucket is collinear with the axis of the through hole 117. The PLC industrial control module controls the pneumatic system via a data cable. Solenoid valve controller 123 closes the pneumatic valve 124 on the left side of both pipes 114 and 113, and simultaneously opens the pneumatic valve 124 on the left side of both pipes 114 and 113. Under the negative pressure generated in the pipeline by the glaze pump device 111, clean water in the water storage tank 112 enters the glaze pump device 111 through pipes 114 and 125, completing the cleaning of the glaze pump. The clean water then enters the storage funnel 102 through pipe 104 above the glaze pump device 111. The paired storage funnels 102 are cleaned. Then, clean water from the storage funnels 102 flows into the plastic cleaning tank through the lower opening of the funnel and pipe 106, thus completing the cleaning of pipe 104 and the discharge pipe 1083. When the plastic cleaning tank rotates with the circular disc 116 and passes above the discharge funnel 119, the pneumatic valve 124 located directly below the circular disc 116 opens under the PLC control module. Clean water from the plastic cleaning tank flows through the through hole 117 of the circular disc 116 and the pneumatic valve 124... 24 falls into the feeding funnel 119, thus completing the cleaning of the through hole 117 and the pneumatic valve 2 124. Then, the clean water accumulated in the feeding funnel 119 flows back into the water storage tank 112 through pipe 1 113, air pump or workshop high-pressure gas pipeline 3, and pipe 3 115, thus completing the cleaning of pipe 1 113, air pump or workshop high-pressure gas pipeline 3, and pipe 3 115. At this time, the cleaning of all pipelines of the main filling and coating equipment 1 has been completed, and the work for the day is completed. The power can be turned off through the servo control box 2.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
