Description

Technical Field

[0001] The utility model belongs to the technical field of lost foam model processing equipment, and more specifically relates to a rapid drying room for air ducts. Background Technique

[0002] Lost foam casting (also known as full-mold casting) is a new casting method in which paraffin or foam models similar in size and shape to the casting are bonded and combined into a model cluster. After being coated with refractory coating and dried, they are vibrated and shaped in dry quartz sand, and poured under negative pressure, so that the models are gasified, and the liquid metal occupies the position of the models and forms castings after solidification and cooling. The key step is to produce foam models. The foam models need to be coated with a layer of coating on the surface and then used for casting after drying. The drying is generally natural cooling and drying, with low efficiency.

[0003] Therefore, how to provide a rapid drying room for air ducts with fast drying speed and high efficiency is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A rapid drying room for air ducts, comprising: a drying room body, a serpentine pipe, a drain pipe, a circulating pump, a bottom plate and a steam heating auxiliary mechanism; the serpentine pipe is horizontally arranged at the upper part of the drying room body, and one end passes through the drying room body and is communicated with the boiler water outlet outside the drying room body, and the other end is communicated with one end of the drain pipe. The other end of the drain pipe extends out of the drying room body and is communicated with the water inlet of the boiler. A circulating pump is installed on the side of the drain pipe close to the serpentine pipe. The bottom plate is horizontally installed at the lower part of the drying room body for placing lost foam models. The steam heating auxiliary mechanism is installed at the top inside the drying room body, and a part of the serpentine pipe is located inside the steam heating auxiliary mechanism.

[0007] Further, the steam heating auxiliary mechanism comprises: a heating box, a steam inlet pipe and a water outlet pipe A; the heating box is installed at the top inside the drying room body. A part of the serpentine pipe on the side communicated with the boiler water outlet is located inside the heating box. One end of the steam inlet pipe is communicated with the waste gas recovery device of the foaming machine, and the other end passes through the drying room body and extends into the heating box. One end of the water outlet pipe A is communicated with the bottom of the heating box, and the other end is communicated with the drain pipe.

[0008] Further, the bottom surface of the heating box is an inclined surface, and the water outlet pipe A is communicated at the lowest point of the inclined surface at the bottom of the heating box.

[0009] Furthermore, a plurality of drain holes are formed on the surface of the bottom plate. A slope is arranged inside the drying room body on the lower side of the bottom plate. A water outlet pipe B is arranged at the low point of the slope. One end of the water outlet pipe B passes through the side wall of the drying room body and is communicated with the drain pipe.

[0010] Furthermore, a plurality of groups of L-shaped clamping plates are installed on the bottom plate for fixing the lost foam pattern.

After all the lost foam patterns are placed, the circulating pump is started to make the hot water in the boiler flow in the serpentine pipe, so as to increase the temperature in the drying room and dry the lost foam pattern. At the same time, the steam in the waste gas recovery device of the foaming machine is utilized inside the heating box to further heat the water inside the serpentine pipe, effectively utilizing the heat. The liquid water formed after the steam is liquefied flows out from the water outlet pipe A and enters the circulation together with the boiler water. Multiple groups of blowers are arranged above the serpentine pipe to make the heat evenly distributed in the whole drying room and quickly dry the lost foam pattern; thus, the drying room of the utility model has high heat utilization rate, fast drying speed, uniform heat distribution and can continuously heat and dry.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to the attached Figures 1-3 , the present invention provides a rapid drying room for air ducts, including: a drying room body 1, a serpentine pipe 2, a drain pipe 3, a circulation pump 4, a bottom plate 5, and a steam heating auxiliary mechanism; the serpentine pipe 2 is horizontally arranged at the upper part of the drying room body 1, and one end passes through the drying room body 1 and is communicated with the boiler water outlet outside the drying room body 1, and the other end is communicated with one end of the drain pipe 3. The other end of the drain pipe 3 extends outside the drying room body 1 and is communicated with the water inlet of the boiler. A circulation pump 4 is installed on one side of the drain pipe 3 close to the serpentine pipe 2. The bottom plate 5 is horizontally installed at the lower part of the drying room body 1 for placing the lost foam model. The steam heating auxiliary mechanism is installed at the top inside the drying room body 1, and a part of the serpentine pipe 2 is located inside the steam heating auxiliary mechanism. The serpentine pipe 2 horizontally covers the entire roof, so that the heat distribution in the drying room is uniform.

[0023] The steam heating auxiliary mechanism includes: a heating box 6, a steam inlet pipe 7, and a water outlet pipe A 8; the heating box 6 is installed at the top inside the drying room body 1, and a part of the serpentine pipe 2 on the side communicated with the boiler water outlet is located inside the heating box 6. One end of the steam inlet pipe 7 is communicated with the waste gas recovery device of the foaming machine, and the other end passes through the drying room body 1 and extends into the heating box 6. One end of the water outlet pipe A 8 is communicated with the bottom of the heating box 6, and the other end is communicated with the drain pipe 3 to recover the condensed water.

[0024] The bottom surface of the heating box 6 is an inclined plane, and the water outlet pipe A 8 is communicated at the lowest point of the inclined plane at the bottom of the heating box 6, so that the condensed water can flow along the inclined plane into the water outlet pipe A 8 and will not accumulate inside the heating box 6.

[0025] The surface of the bottom plate 5 is provided with a plurality of drain holes 9. Inside the drying chamber body 1 below the bottom plate 5, there is a slope 10. The low point of the slope 10 is provided with a water outlet pipe B 11. One end of the water outlet pipe B 11 passes through the side wall of the drying chamber body 1 and is communicated with the drain pipe 3.

[0026] A plurality of groups of L-shaped clamping plates 12 are installed on the bottom plate 5 for fixing the lost foam pattern. The L-shaped clamping plates 12 can be used in groups of two to clamp the two ends of the lost foam pattern, or in groups of four to clamp the four bottom corners of the lost foam pattern. After clamping, the lost foam pattern is in a vertically placed state. This is because there are residual water droplets on the surface of the formed lost foam pattern. Vertically placing it can make the water droplets flow downward and fall onto the bottom plate 5, and be discharged through the drain holes 9, and finally enter the drain pipe 3 to circulate with the boiler water together, improving the drying efficiency.

[0027] A plurality of groups of blowers 13 are installed at the top inside the drying chamber body 1.

[0028] The serpentine pipe 2 is fixed to the side wall of the drying chamber body 1 through brackets 14, and the number of the brackets 14 is multiple groups.

[0029] The structure of the present utility model is simple and convenient to use. When in use, the lost foam pattern to be dried is vertically placed on the L-shaped clamping plates 12. Since there are multiple groups of L-shaped clamping plates 12 in the drying chamber of the present utility model, batch drying can be carried out. After all the lost foam patterns are placed, the circulation pump 4 is started to make the hot water in the boiler flow in the serpentine pipe 2, increasing the temperature inside the drying chamber to dry the lost foam pattern. At the same time, inside the heating box 6, the steam in the waste gas recovery device of the foaming machine is used to further heat the water inside the serpentine pipe 2, effectively utilizing the heat. The liquid water formed after the steam liquefies flows out from the water outlet pipe A 8 and enters the circulation together with the boiler water. The residual water droplets on the surface of the lost foam pattern can flow downward and fall onto the bottom plate 5 when vertically placed, and be discharged through the drain holes 9, and finally enter the drain pipe 3 to circulate with the boiler water together. A plurality of groups of blowers 13 are arranged above the serpentine pipe 2 to make the heat evenly distributed throughout the drying chamber, quickly drying the lost foam pattern; thus making the heat utilization rate of the drying chamber of the present utility model high, the drying speed fast, the heat distribution uniform, and it can continuously generate heat for drying.
