Description

Technical Field

[0001] This invention relates to the field of electric drying technology, specifically to an electric drying device for protecting slag. Background Technology

[0002] Protective slag is a commonly used material in industrial production, which can be used to achieve insulation and heat preservation. Protective slag is generally granulated using a spray granulation tower. The granulated protective slag contains a certain amount of moisture, so it needs to be dried using a drying device before the finished product can be obtained.

[0003] In the prior art, Chinese Patent No. CN211668225U discloses a blower drying device, including a fixed outer shell. A power cord is movably mounted on one outer surface of the fixed outer shell, and a power plug is fixedly mounted on the end of the power cord away from the fixed outer shell. An air inlet mesh is fixedly mounted on the front surface of the fixed outer shell, and a start knob is movably mounted on the front surface of the fixed outer shell to one side of the air inlet mesh. An airflow conversion sleeve is provided on one outer surface of the fixed outer shell, and an air outlet is opened on one outer surface of the airflow conversion sleeve. Multiple airflow adjustment plates are movably mounted on the inner side of the airflow conversion sleeve, inside the air outlet. The blower drying device of this utility model can increase the contact area of ​​the exhaust air, quickly heat up the blown air, and increase the heating temperature, thereby improving the drying efficiency. It can also adjust the blowing air direction angle, which is convenient for drying operations in different locations.

[0004] The aforementioned device utilizes a blower structure to transport gas during use. The transported gas is then heated by a heating device to achieve the purpose of drying. However, in actual use, the gas enters the interior through the air inlet mesh. Over a long period of use, dust in the air will accumulate at the air inlet mesh, causing blockage. The blocked air inlet mesh will affect the air intake, thereby affecting the overall performance of the device.

[0005] In the prior art, Chinese Patent No. CN207299814U discloses an energy-saving and environmentally friendly protective slag baking device, including a vertical metal box, supporting legs, a partition plate, a stirrer, a cantilever, a metal thermometer, an exhaust valve, a feed cover, a discharge box door, a coiled tube fixing plate, a refractory layer, and a switch valve. The bottom of the vertical metal box is equipped with supporting legs, and the partition plate is horizontally installed inside the vertical metal box, dividing it into upper and lower parts. A stirrer is located in the upper space of the partition plate, and a metal thermometer is located on the outer wall of the vertical metal box in the upper space of the partition plate. A coiled tube is located in the lower space of the partition plate, and the coiled tube is connected to a metal conduit outside the vertical metal box. This invention uses a row of parallel coiled tubes, employing high-temperature waste gas or steam generated in a boiler, utilizing waste heat radiation for baking. This reduces costs while achieving uniform baking, further improving heat transfer efficiency, enhancing the quality of the protective slag, and achieving energy saving and emission reduction.

[0006] The aforementioned device is used to generate heat through combustion for drying purposes. However, in actual use, the heat conversion efficiency of energy combustion is low, which leads to resource waste and is not in line with the concept of environmental protection. Summary of the Invention

[0007] The purpose of this invention is to provide an electric drying device for protective slag, so as to solve the problems mentioned in the background art, such as dust blockage of the air inlet screen affecting the air intake volume and the high energy consumption and environmental disadvantages of the combustion method.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an electric drying device for protective slag, comprising an outer casing fixedly installed on the top of a protective slag production tower, a control panel fixedly installed on the outside of the outer casing, and further comprising:

[0009] A blower is fixedly installed on the outer surface of the outer casing of the device, and a drying pipe connected to the inside of the protective slag production tower is fixedly installed on the lower surface of the blower.

[0010] The outer surface of the outer casing of the device is equipped with a filter mechanism that blocks dust from entering, and the filter mechanism is equipped with a dust removal mechanism to clean it and prevent clogging.

[0011] The device has solar panels fixedly installed on the left and right sides of the upper surface of the outer casing. The solar panels are used to assist in powering the entire device, and a cleaning mechanism is provided on the outside of the solar panels for regular cleaning.

[0012] The device has a horizontally distributed main heater fixedly installed inside the outer casing, and two flow guide baffles are also fixedly installed inside the outer casing. The two flow guide baffles are staggered from left to right, and an auxiliary heater is fixedly installed on the outer surface of the flow guide baffles.

[0013] Preferably, the filtration mechanism includes an air inlet fixedly installed on the upper surface of the outer casing of the device and a dust filter installed inside the air inlet, and the dust removal mechanism includes a dust removal nozzle fixedly installed on the inner wall of the air inlet and a blower airbag that supplies air to the dust removal nozzle. When the blower airbag is compressed, the air inside is ejected from the dust removal nozzle to achieve the purpose of cleaning the upper surface of the dust filter.

[0014] Preferably, the blower airbag is fixedly installed inside the side wall of the air inlet, and a compression plate is provided below the blower airbag to compress it. The compression plate is fixedly connected to the dust filter. The compression plate moves up and down synchronously by the up and down movement of the dust filter, thereby causing the compression plate to compress the blower airbag.

[0015] Preferably, the extrusion plate drives the dust filter to form an up-and-down sliding structure with the sliding groove opened inside the air inlet, and a return spring connected to the extrusion plate is fixedly installed inside the sliding groove. The elastic return effect of the return spring allows the dust filter to vibrate up and down inside the air inlet.

[0016] Preferably, a connecting rod is fixedly installed at the middle position of the lower surface of the dust filter to drive its movement, and the bottom end of the connecting rod extends into the interior of the outer casing of the device, and the bottom end of the connecting rod is distributed horizontally from left to right, so that the dust filter can be pushed to move upward through the connecting rod.

[0017] Preferably, the lower sides of the left and right ends of the connecting rod are provided with push cams to push it, and the push cams are rotatably connected to the outer casing of the device. Rotating blades are coaxially fixedly installed on the side of the push cams, and the rotating blades drive the extrusion cams to rotate synchronously, thereby causing the extrusion cams to push the connecting rods to move upward.

[0018] Preferably, the cleaning mechanism includes a cleaning nozzle fixedly installed on the outside of the solar panel and a storage box fixedly installed inside the outer casing of the device. The storage box and the cleaning nozzle are connected by a water pipe, and water in the storage box can be sprayed out from the cleaning nozzle through the water pipe to clean the solar panel.

[0019] Preferably, a sealing plate that slides and seals against the inner wall is fitted to the lower end of the storage box, and a condensation plate with a perforated structure is fixedly installed at the upper end of the storage box, and the storage box is made of heat-insulating material.

[0020] Preferably, a return pipe connected to the protective slag production tower is installed through the upper surface of the storage tank. The air containing water vapor during drying is returned to the storage tank through the return pipe. The hot air after drying the protective slag, mixed with water vapor, enters the storage tank through the return pipe. The water vapor forms water droplets under the condensation of the condensing plate and is stored in the storage tank.

[0021] Preferably, a conveying pipe is fixedly installed through the outer side of the outer casing of the device, and the bottom end of the conveying pipe is connected to the drying pipe and pressurized by an air pump. A first diverter pipe and a second diverter pipe are fixedly installed at the front end of the conveying pipe. The first diverter pipe is aligned with the rotating blade, and the second diverter pipe is connected to the inside of the storage box. The air blown out of the first diverter pipe blows the rotating blade to rotate, and the air blown out of the second diverter pipe pushes the sealing plate to move upward.

[0022] Compared with the prior art, the beneficial effects of this invention are as follows: This electric drying device for slag protection adopts a novel structural design, enabling the device to heat air electrically to achieve the purpose of drying during use. Furthermore, it utilizes a solar panel to achieve further energy-saving and environmentally friendly effects. A dust filter is used to filter dust from the air, preventing clogging that could affect the device's performance. The airflow from the drying process drives the rotating blades, ultimately causing air from the blower to be ejected from the cleaning nozzles. Combined with the vibration of the dust filter, this achieves the cleaning purpose. The specific details are as follows:

[0023] 1. The combined use of the baffle plate, solar panel, main heater and auxiliary heater utilizes electrical energy to heat the air inside the outer casing of the device. Electric heating is more energy-efficient and environmentally friendly than combustion heating. The gas is then transported to dry the protective slag. The solar panel can provide auxiliary power when there is sufficient sunlight, thus achieving more effective energy saving and environmental protection. At the same time, the baffle plate guides the air, allowing the air to stay inside the outer casing of the device for a longer time, improving the heating effect.

[0024] 2. Through the use of the filtration and dust removal mechanisms, the dust in the air is first filtered by the dust filter during the blowing process. At the same time, part of the gas in the drying pipe is sprayed out from the first diversion pipe through the conveying pipe, blowing the rotating blades. Then, under a series of transmission actions, the dust filter vibrates up and down. Meanwhile, the extrusion plate squeezes the blower airbag, causing the air in the blower airbag to be sprayed out from the dust removal nozzle. The airflow is used to clean the dust accumulated on the surface of the dust filter, avoiding blockage.

[0025] 3. Through the use of the cleaning mechanism, the dried hot air mixed with water vapor enters the storage tank through the return pipe. After condensation on the condenser plate, water droplets are formed and stored in the storage tank. Then, part of the gas in the delivery pipe is discharged through the second diversion pipe. Under the action of air pressure, the sealing plate is pushed upward, so that the sealing plate delivers the stored water through the connecting hose and sprays it out from the cleaning nozzle, thereby achieving the purpose of automatic cleaning of the solar panel.

The furnace frame is welded from 10# large channel steel and 4mm Q235 steel plate, ensuring the overall strength of the furnace, the frame structure does not sag or deform, and it is aesthetically pleasing and does not deform over long-term use. The main material of the furnace lining is 1260 type aluminosilicate refractory fiber compressed block with a long-term service temperature of 1050 degrees Celsius, which has the advantages of low thermal conductivity, light weight, good thermal insulation performance, easy construction, and long service life, and can effectively reduce the heat storage and heat dissipation loss of the furnace lining, significantly saving energy. A control panel 2 is fixedly installed on the side of the outer casing 1. The device also includes a blower 4 fixedly installed on the outer surface of the outer casing 1, with the blower 4 being a 22kW unit at the outlet. The high-temperature induced draft fan ensures that all the heat inside the furnace is carried out of the furnace, preventing overheating and heat accumulation. A drying pipe 3, connecting to the inside of the protective slag production tower, is fixedly installed on the lower surface of the blower 4. A filter mechanism is installed on the upper surface of the outer casing 1 to block dust, and a cleaning mechanism is installed inside the filter to prevent clogging. A horizontally distributed main heater 8 is fixedly installed inside the outer casing 1, and two flow guide baffles 9 are also fixedly installed inside the outer casing 1, with the two baffles 9 staggered left and right. A secondary heater 10 is fixedly installed on the outer surface of the flow guide baffles 9. The main heater 8 and the secondary heater 10 are made of 0Cr21A16Nb high-temperature resistance alloy wire, which is safe, reliable, and quick and easy to install and maintain. The resistance wire is manufactured using a special mold to ensure it is not damaged during processing. The resistance wire is installed using a special fixing structure, which is convenient for installation, maintenance, and replacement.

[0038] The filtration mechanism includes an air inlet 5 fixedly installed on the upper surface of the outer casing 1 of the device and a dust filter 6 installed inside the air inlet 5. The dust removal mechanism includes a dust removal nozzle 11 fixedly installed on the inner wall of the air inlet 5 and a blower airbag 15 that supplies air to the dust removal nozzle 11. The blower airbag 15 is fixedly installed inside the side wall of the air inlet 5, and a compression plate 16 is provided below the blower airbag 15 to compress it. The compression plate 16 is fixedly connected to the dust filter 6, and the compression plate 16 drives the dust filter 6 to slide against the sliding groove 17 opened inside the air inlet 5. The two sides form an up-and-down sliding structure, and a return spring 18 connected to the extrusion plate 16 is fixedly installed inside the sliding groove 17. A connecting rod 12 that drives the dust filter 6 is fixedly installed in the middle of the lower surface of the filter screen 6. The bottom end of the connecting rod 12 extends into the inner part of the outer box 1 of the device, and the bottom end of the connecting rod 12 is distributed horizontally to the left and right. Pushing cams 19 are provided on the lower side of the left and right ends of the connecting rod 12 to push it. The pushing cams 19 are rotatably connected to the outer box 1 of the device, and rotating blades 20 are fixedly installed on the side of the pushing cams 19 coaxially.

[0039] When using the device, first, the entire device is fixedly installed at the top of the granulation tower for producing protective slag. Then, the power is turned on, and the blower 4 is turned on to draw external air into the outer casing 1 of the device through the air inlet 5. The air is then heated by the combined heating action of the main heater 8 and the auxiliary heater 10. The air flows under the guidance of the baffle 9, increasing its residence time inside the outer casing 1. The heated air enters the granulation tower through the drying pipe 3 to dry the protective slag. During operation, the valve of the conveying pipe 21 is opened periodically. At this time, some of the air in the conveying pipe 21 is ejected from the first diversion pipe 2101 through the conveying pipe 21, and the air pump at the connection point achieves a pressurization effect. Due to the diameter of the first diversion pipe 2101... The smaller size increases the impact force of the exhaust gas. The air ejected from the first diversion pipe 2101 blows the rotating blade 20 to rotate. During the rotation of the rotating blade 20, it drives the push cam 19, which is fixedly installed with it, to rotate. The rotating blade 20 pushes the connecting rod 12 to move upward, so that the connecting rod 12 drives the dust filter 6 to move synchronously. Then, under the elastic action of the return spring 18, the dust filter 6 is reset downward, and finally the dust filter 6 vibrates up and down, thereby loosening the dust accumulated on the dust filter 6. During the upward movement of the dust filter 6, it drives the extrusion plate 16 connected with it to move synchronously, so that the extrusion plate 16 squeezes the blower air bag 15 above. At this time, the air in the blower air bag 15 is ejected from the dust cleaning nozzle 11 to clean the dust on the upper surface of the dust filter 6.

[0040] Solar panels 7, arranged at an angle, are fixedly installed on the left and right sides of the upper surface of the outer casing 1 of the device. The solar panels 7 assist in powering the entire device, and a cleaning mechanism is provided on the outside of the solar panels 7 for periodic cleaning. The cleaning mechanism includes a cleaning nozzle 13 fixedly installed on the outside of the solar panels 7 and a storage tank 14 fixedly installed inside the outer casing 1 of the device. The storage tank 14 and the cleaning nozzle 13 are connected by a water pipe 25. A sealing plate 23 that slides and seals against the inner wall is installed at the lower end of the inside of the storage tank 14, and a perforated condenser is fixedly installed at the upper end of the inside of the storage tank 14. Plate 24, and storage tank 14 is made of heat insulation material. A return pipe 22 connecting the protective slag production tower is installed through the upper surface of storage tank 14. The air containing water vapor during drying is returned to storage tank 14 through the return pipe 22. A conveying pipe 21 is fixedly installed through the outer side of the outer casing 1 of the device. The bottom end of the conveying pipe 21 is connected to the drying pipe 3 and pressurized by an air pump. A first diversion pipe 2101 and a second diversion pipe 2102 are fixedly installed at the front end of the conveying pipe 21. The first diversion pipe 2101 is aligned with the rotating blade 20, and the second diversion pipe 2102 is connected to the inside of storage tank 14.

[0041] The solar panel 7 on the upper surface of the outer casing 1 of the device converts solar energy to generate electricity, thereby assisting in power supply. The hot air after drying the protective slag, mixed with water vapor, enters the storage tank 14 through the return pipe 22. The water vapor is condensed by the condenser plate 24 and forms water droplets, which are stored in the storage tank 14. During the cleaning of the dust filter 6, some air in the conveying pipe 21 is sprayed out from the second diversion pipe 2102. Under the action of air pressure, the sealing plate 23 inside the storage tank 14 moves upward, so that the sealing plate 23 squeezes the water collected in the storage tank 14 and sprays it out from the cleaning nozzle 13 through the connecting water pipe 25 to clean the surface of the solar panel 7, thereby preventing dirt from affecting the conversion efficiency of the solar panel 7.
