Description

Technical Field

[0001] The invention relates to the technical field of drying equipment, in particular to hydrogen energy drying equipment. Background Art

[0002] Drying equipment refers to a combination of a series of mechanical equipment that uses certain technical means to dry the moisture or other liquids on the surface of an object. The popular drying technologies are mainly ultraviolet drying, infrared drying, electromagnetic drying and hot air drying. They have their own characteristics and are widely used in drying various mechanical equipment and food. Drying equipment generally has several modes such as belt drying, drum drying, box drying, tower drying, etc. It is mainly used in mineral processing, building materials, metallurgy, chemical industry, printing and other departments to dry materials with a certain humidity or particle size. The heat sources include coal, electricity, gas, etc. The materials are dried in hot air flow and radiation.

[0003] Generally, after metal castings are cast, they need to be cut and polished, which will produce machining debris and cutting fluid. Therefore, the metal castings need to be cleaned and dried later. However, during the cleaning and drying process of some existing castings with complex inner cavities, the metal powder remaining in the complex inner cavity is difficult to clean up, and it is easy for metal powder to remain in the complex inner cavity, affecting the processing quality of the product. In addition, the cleaning process is relatively cumbersome, which reduces production efficiency. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that in the process of cleaning and drying some castings with complex inner cavities, the metal powder remaining in the complex inner cavity is difficult to clean up, and metal powder is likely to remain in the complex inner cavity, affecting the processing quality of the product, and the cleaning process is relatively cumbersome, which reduces the production efficiency, and provide a hydrogen drying equipment.

[0005] The purpose of the present invention is achieved through the following technical solutions: a hydrogen drying device, comprising a drying box, an air inlet pipe and an air outlet pipe are respectively installed on both sides of the drying box, the air inlet pipe and the air outlet pipe are extended into the drying box, and a fixed platform is installed between the air inlet pipe and the air outlet pipe, a rotatable rotating block is installed on the fixed platform, a mounting platform is installed on the rotating block, a first motor is installed in the fixed platform, a power output end of the first motor is connected to the rotating block, and the fixed platform can drive the rotating block and the mounting platform to rotate in the drying box; two groups of clamping plates responsible for clamping metal castings are installed in the middle of the mounting platform, and blowing plates and suction plates are respectively installed on both sides of the mounting platform, and multiple groups of blowing nozzles and suction nozzles are respectively installed on the side of the blowing plate and the suction plate close to the mounting platform, and the air inlet end of the blowing plate is rotatably connected to the air outlet end of the air inlet pipe through an air guide pipe. The air outlet end of the air intake plate is rotatably connected to the air inlet end of the air outlet duct through the air guide duct. The first motor can be arranged to drive the mounting platform and the metal casting on the mounting platform to rotate, so that the dust and metal powder on the surface of the metal casting can be quickly removed from the metal casting under the action of centrifugal force. At the same time, the dust and metal powder remaining in the inner cavity of the metal casting can be lifted up into a dust-like state, which is convenient for blowing out from the inner cavity of the metal casting under the blowing action of the air blowing nozzle, thereby realizing the cleaning of the dust and metal powder in the complex inner cavity of the metal casting, improving the cleaning effect of the metal casting, and thus improving the processing efficiency of the equipment. The air guide duct, the air blowing plate and the air blowing nozzle are arranged to cooperate and rotate with the rotation of the metal casting on the mounting platform, so as to always keep the blowing cleaning of the metal casting, and further improve the cleaning effect.

[0006] The air inlet end of the air inlet pipe is connected to the hot air box, an electric heating element is installed in the hot air box, and the air outlet end of the hot air box is connected to the air inlet pipe through a blower. A hydrogen fuel cell is arranged on one side of the hot air box, and the hydrogen fuel cell is electrically connected to the electric heating element. The two ends of the hydrogen fuel cell are respectively connected to a hydrogen pipeline and an oxygen pipeline. By arranging the hydrogen fuel cell, clean energy and electricity can be provided, which is more environmentally friendly.

[0007] The air outlet end of the air outlet duct extends to the collecting box through the negative pressure fan, the collecting box is connected to the bottom of the drying box, the air outlet end of the collecting box is connected to the air inlet end of the hot air box, and a dust collector is installed between the air outlet end of the collecting box and the air inlet end of the hot air box. By installing the dust collector between the air outlet end of the collecting box and the air inlet end of the hot air box, dust can be prevented from flowing into the hot air box with the air flow. The dust collector collects the dust, and the air flow returning to the hot air box can recycle the waste heat in the air flow and reduce the loss of heat energy.

[0008] A further technical solution is that a vibration platform is installed on the mounting platform, an electric slide is installed on the vibration platform, two sets of clamps are respectively connected to the moving ends of the electric slide, and a vibration damper is installed between the mounting platform and the vibration platform. The clamps are connected to the moving ends of the electric slide to facilitate the adjustment of the distance between the two sets of clamps, thereby clamping metal castings of different sizes. At the same time, the electric slide can provide continuous clamping force, thereby ensuring stable support for the metal castings.

[0009] A further technical solution is that a hydraulic cylinder is installed on the upper part of the mounting platform, and a pressure plate is installed on the lifting end of the hydraulic cylinder. The two sets of clamps are symmetrical about the pressure plate, and the pressure plate and the two sets of clamps are arranged in a triangle. The pressure plate and the two sets of clamps are arranged in a triangle, which can further improve the stability of the metal casting on the mounting platform and prevent the metal casting from falling off during rotation.

[0010] A further technical solution is that both the blowing nozzle and the suction nozzle are connected to an external PLC control end, and the external PLC control end is responsible for controlling the opening and closing of the blowing nozzle and the suction nozzle. By arranging the blowing nozzle and the suction nozzle to be connected to the external PLC control end, different blowing nozzles and suction nozzles can be controlled separately, and air can be exhausted and inhaled into complex cavities at different positions on the metal casting, thereby improving the cleaning effect of the blowing nozzle and the suction nozzle on dust in the complex cavity.

[0011] A further technical solution is that a dust hood is installed in the drying box, the air inlet end of the dust hood is arranged above the blowing nozzle, and the air outlet end of the dust hood is connected to the air outlet pipe. By arranging the dust hood above the blowing nozzle, the dust in the drying box can be collected, and at the same time, the cleaning effect of the dust at the opening of the metal casting with only a single open cavity is improved.

[0012] A further technical solution is that a temperature sensor is installed on the mounting platform, the temperature sensor is connected to an external PLC control end, the external PLC control end is connected to the temperature control switch on the electric heating element, and the temperature sensor and the external PLC control end are connected to each other so as to effectively monitor the temperature inside the drying box. At the same time, the external PLC controls the heating temperature of the electric heating element through the temperature control switch on the electric heating element, thereby controlling and adjusting the temperature inside the drying box.

[0013] A further technical solution is that an electromagnet is installed in the collection box, and the electromagnet corresponds to the air outlet of the negative pressure fan and the bottom of the drying box respectively. By setting the electromagnet, the metal powder in the dust entering the collection box can be adsorbed, thereby separating the metal powder from other dust and effectively recycling the metal powder;

[0014] A second motor is installed on the collection box, and the power output end of the second motor extends into the collection box and is connected to the electromagnet. The second motor is arranged to drive the electromagnet to rotate, which can improve the uniform adsorption of metal powder by the surface of the electromagnet and improve the metal powder recovery effect of the electromagnet.

[0015] A detachable dust hopper is installed at the inner bottom of the collection box. The dust hopper can be easily collected and cleaned for dust or metal powder in the collection box.

[0016] A further technical solution is that an air cavity is provided at the air inlet end of the air inlet duct, and multiple groups of through holes are opened at the air outlet end of the air inlet duct, and the multiple groups of through holes are all located in the air cavity. The air cavity and the through holes are arranged in coordination to ensure that the air inlet end of the air inlet duct can continuously supply air while rotating on the air inlet duct.

[0017] A further technical solution is that both ends of the air cavity are rotatably connected to the air inlet duct through sealed bearings. The sealed bearings at both ends of the air cavity can ensure the smooth rotation of the air guide duct and the air inlet duct, and at the same time have a certain sealing function to avoid waste caused by leakage of hot air.

[0018] The present invention has the following advantages: the present invention can drive the mounting platform and the metal casting on the mounting platform to rotate by arranging a first motor, so that the dust and metal powder on the surface of the metal casting can quickly fall off the metal casting under the action of centrifugal force, and at the same time, the dust and metal powder remaining in the inner cavity of the metal casting can be raised into a dust-like state, which is convenient for blowing out from the inner cavity of the metal casting under the blowing action of the blowing nozzle, thereby realizing the cleaning of the dust and metal powder in the complex inner cavity of the metal casting, improving the cleaning effect of the metal casting, and thus improving the processing efficiency of the equipment.
