Technical Field

[0001] The invention relates to the technical field of dry-wet separation equipment, and in particular to a cold dryer for laser cutting. Background Art

[0002] Cold dryer is the abbreviation of refrigerated dryer. Cold dryer adopts new technology and belongs to the air source processing component in the pneumatic system. In laser cutting, the cold dryer can be matched with an evaporator to cool the laser and dehumidify the air medium.

[0003] Existing cold dryers mostly dry the air by cooling the air and condensing the moisture in the air. However, when cooling the air, the hot and humid air is directly blown to the low-temperature condenser, the condenser is overloaded and the heat exchange is insufficient. Therefore, we propose a cold dryer for laser cutting to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a cold dryer for laser cutting.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cold dryer for laser cutting, comprising a precooling component and a heat exchange component, characterized in that dispersion components are installed on the left and right sides of the heat exchange component, the precooling component is installed on the top of the dispersion component, the precooling component comprises an air inlet pipe, a spiral sheet is installed on the outside of the air inlet pipe, the dispersion component comprises an air inlet manifold and an air outlet manifold, the left end of the air inlet pipe is installed in a conductive manner with the air inlet manifold, the heat exchange component comprises a condenser, a shell is installed on the outside of the condenser, the right end of the shell is conductively connected to the air outlet manifold, and the upper end of the air outlet manifold is connected to the exhaust pipe;

[0007] To ensure stable cooling of the laser during laser cutting, high-humidity air from the outside will enter the pre-cooling component. The air inlet pipe is equipped with spiral blades to cool the high-humidity and high-temperature air flowing through the interior. The air then enters the outer shell through the air inlet manifold and comes into contact with the condenser to condense the moisture in the air into water droplets. The dry and cold air condensed by the condenser will be discharged through the air outlet manifold. The air cooling operation at the air inlet pipe position reduces the temperature of the air entering the heat exchange component in advance, and a small amount of condensation is performed at the air inlet pipe position to reduce the workload of the condenser.

[0008] Preferably, a sleeve is installed on the outer side of the spiral blade, which is passed through from left to right. The inner wall of the sleeve, the outer wall of the air inlet pipe and the outer wall of the spiral blade are arranged to form a spiral air passage. An external fan is installed at the left end of the sleeve.

[0009] The sleeve is put on the outside of the spiral blade to form a spiral air duct. The external fan provides high-speed airflow for the air duct to take away the heat at the spiral blade position, reduce the temperature of the air inlet pipe, and improve the air cooling efficiency.

[0010] Preferably, the sleeve has an annular cavity built therein, a through pipe in an annular array is installed at the right end of the sleeve, an air distribution ring is installed at the right end of the through pipe, and the lower right part of the air distribution ring is conductively connected to the upper end of the air outlet manifold;

[0011] The sleeve has an annular cavity built in it, and the air exhausted from the heat exchange component is dispersed through the through pipe and evenly enters the annular cavity. The sleeve is connected to the spiral blade and can be cooled synchronously, so that the exhausted air is cooled again and condensed and dehumidified again.

[0012] Preferably, a connecting pipe with an annular assembly is installed at the left end of the sleeve, an exhaust shell is installed at the left end of the connecting pipe, and the exhaust shell is conductively connected to the exhaust pipe;

[0013] The cold and dry air in the sleeve will enter the exhaust shell from the connecting pipe and be centrally guided to the exhaust duct by the exhaust shell. The exhaust duct can be connected to an external cyclone separator for supplementary mechanical dehumidification to improve the dehumidification effect.

[0014] Preferably, a drain pipe is installed through the bottom end of the sleeve, a bypass pipe is installed at the bottom end of the air distribution ring, and the drain pipe and the bypass pipe are connected;

[0015] When high-humidity air passes through the sleeve and the air distribution ring, the condensed water generated can gather at the bottom of the sleeve and the air distribution ring, and then be discharged centrally through the drain pipe and bypass pipe to prevent water accumulation in the sleeve and the air distribution ring.

[0016] Preferably, a vertical plate is installed at the top of the condenser, and support plates are installed on the front and rear side walls of the vertical plate, and a slit is left between the support plate and the left and right inner walls of the shell;

[0017] The vertical plates can effectively increase the effective attachment surface area of ​​the condenser, the support plates can further increase the surface area, and when high-humidity air passes through, the setting of the slits can ensure that the air is in full contact with all the support plates and vertical plates, which can effectively contact and cool the high-humidity air, condense the moisture efficiently, and dry the air.

[0018] Preferably, the condenser is provided with guide holes on both sides of the front and rear sides of the vertical plate, and a drainage shell matching with the guide holes is installed at the bottom end of the shell;

[0019] The guide holes collect the condensed water generated on the vertical plates and guide it to the lowest point of the drainage shell so that the condensed water can be quickly discharged. An end cover is installed at the front end of the drainage shell to seal the front end of the drainage shell during dehumidification, temporarily storing the condensed water in the drainage shell and discharging it centrally after dehumidification to prevent waste of cold dry air.

[0020] Preferably, the air inlet manifold comprises a plurality of vertical extensions, a port is provided at the lower end of the extension, mirror-symmetrical air outlets and air outlets are installed on the left and right sides of the housing, and a guide portion cooperating with the air outlet is installed at the lower part of the air outlet manifold;

[0021] The setting of the extension part can provide multiple air outlet ports, and the air outlet manifold provides multiple guide parts, so that the air entering the air outlet can be discharged from the air outlet, entering from the left side and discharged from the right side. The air can cross the entire shell and make full use of the internal space of the shell.

[0022] Preferably, the vertical plates are provided with a plurality of groups arranged side by side in front and back, the number of the extension parts is the same as that of the vertical plates, and the length of the extension parts gradually changes from longer in the front to shorter in the back;

[0023] The high-humidity air is evenly dispersed into the interior of the shell, and the surface area of ​​multiple groups of vertical plates and support plates is fully utilized. The air outlets are mirror-symmetrical, so that the air entering from the bottom is discharged from the top, and the air entering from the top is discharged from the bottom. This can extend the air's movement path inside the shell and ensure sufficient contact.

[0024] Preferably, the condenser is an electric cooling condenser, the condenser has an electric cooling plate built in, and the condenser is connected to an external power supply and an external control device through a wire;

[0025] The electric cooling condenser can control the temperature of the electric cooling plate through an external control device, and the temperature adjustment of the electric cooling plate is faster. Compared with the cold water condenser, it does not need to be matched with liquid heat exchange medium and pump. It has a simple structure and is easy to use.

[0026] Compared with the prior art, the advantages of this cold dryer for laser cutting are:

[0027] 1. Through the setting of the pre-cooling component, a spiral blade is installed on the outside of the air inlet pipe, and a sleeve that passes through the left and right is set on the outside of the spiral blade. An external fan is installed at the opening of the sleeve. The air inlet pipe can be pre-cooled and cooled by air cooling, and the high-humidity air can be pre-condensed to produce part of the condensed water and effectively cool the air. When the effectively cooled and partially condensed high-humidity air contacts the condenser again, it can be quickly condensed to reduce the heat absorption power of the condenser;

[0028] 2. Through the setting of the heat exchange component, the heat exchange component includes multiple vertical plates, which are installed above the condenser to transfer the low temperature of the condenser to the upper part of the shell. The vertical plate has a large surface area and a large contact area with the high-humidity air, which can provide a larger heat exchange space. The condensed water flows downward, and the condensed and dehumidified air will enter the annular cavity of the sleeve. The inner wall of the sleeve is connected to the spiral sheet to supplement the condensation and cooling of the low-humidity air to ensure that the discharged air is low-temperature and dry;

[0029] 3. Through the setting of the dispersion component, a four-way air inlet manifold is installed at the left end of the air inlet pipe to lead the high-humidity air to the heat exchange component through three channels to disperse the air inlet, and a corresponding air outlet manifold is installed at the right end of the shell to lead out the condensed air. The air outlet of the air inlet manifold is arranged in an up-and-down staggered manner, and the air inlet and outlet of the air outlet manifold are mirror-symmetrical, so that the air can fully contact the heat exchange component, and the heat exchange effect is improved by evenly dispersing the air.
