Description

Technical Field

[0001] The present application belongs to the technical field of drying equipment, and in particular, relates to a drying equipment for casting production and a method of using the same. Background Art

[0002] The lost foam used in a large number of foundry industries, whether yellow or white, is made by gluing quartz sand to plastic models. It requires multiple layers of brushing and pasting, so it needs to be dried to dehydrate and dry. When molten iron is poured, the plastic immediately vaporizes and disappears, and the molten iron fills the mold cavity. At this time, if there is residual moisture in the lost foam, a large amount of water vapor will be generated immediately, causing pores and slag holes in the casting and making it scrapped. When the mold begins to dry, the surface of the mold is heated first, and the surface moisture evaporates. The dried rubber quickly forms a hard shell, and the solidified rubber forms a seal between the quartz particles, blocking the diffusion of internal moisture, so it is difficult to dry thoroughly. In order to prevent the plastic model from softening and deforming, a high drying temperature cannot be used. It often takes a long time to bake, which consumes a lot of energy and has low efficiency.

[0003] The existing Chinese patent with publication number CN112985046B discloses a heat pump drying device and a lost foam drying process based on the device, including a drying room and a heat pump unit, the heat pump unit is provided with a partition board, the partition board separates the heat pump unit into an inner box and an outer box, the inner box is fixed in the drying room, a condenser and a water trap are provided in the inner box, an evaporator, a compressor and an expansion valve are provided in the outer box, and the condenser, the water trap, the compressor, the evaporator and the expansion valve are connected in sequence to form a refrigeration cycle.

[0004] Although the above drying equipment achieves low energy consumption drying, there are still some problems with the drying equipment. The internal space of the drying equipment is large, the heating speed in the early stage of drying is slow, and it cannot quickly enter the efficient drying effect. The cooling speed after drying is slow, and the product in the drying equipment cannot be quickly replaced. Summary of the invention

[0005] The purpose of this application is to provide a drying device for casting production and a method of using the same in order to solve the above-mentioned technical problems, so as to enable alternate drying and shorten the heating time to reach the efficient drying temperature and the cooling time after the drying is completed.

[0006] The present application provides a drying device for casting production, comprising:

[0007] The drying room has two drying chambers, a static pressure chamber is arranged on the top of the drying room, and a connecting hole for connecting with the corresponding drying chamber is arranged between the static pressure chamber and the corresponding drying chamber;

[0008] The heat pump unit is installed on the drying room and corresponds to the drying chamber respectively. The heat pump unit is connected to the drying room through an air guide channel. The heat pump unit includes a heating system and a dehumidification system.

[0009] The return air outlet is placed in the drying room and connected to the corresponding drying chamber;

[0013] The drying room has two drying chambers that can be controlled separately. The hot air generated by the heating system of the heat pump unit is introduced into the drying chamber for drying. The evaporated moisture flows with the air through the return air port to the heat pump unit. After the moisture is removed by the dehumidification system of the heat pump unit, it enters the drying chamber again through the heating system. The return air port is connected to the connecting channel and the air guide channel. The connectivity between the return air port and the connecting channel and the air guide channel is controlled by an adjusting mechanism. The air between the two drying chambers can be exchanged through the adjusting mechanism.

The temperature in one drying room is lowered to facilitate the quick removal of items in the drying room, and the other drying room can be quickly heated to a stable drying temperature. When the hot and cold air in the two drying rooms are exchanged, when the cold air enters the hot drying room, the heating system of the heat pump unit in the corresponding drying room is shut down and the dehumidification system keeps working. When the hot air enters the cold drying room, the heating system and dehumidification system of the heat pump unit in the corresponding drying room are worked. The hot air generated by the heat pump unit first enters the static pressure chamber, and then circulates through the connecting hole between the static pressure chamber and the drying chamber. The connection between the two static pressure chambers is controlled by the partition mechanism. The static pressure chamber and the drying chamber are connected through the connecting hole.

[0077] The regulating mechanism 400 is installed and connected with the return air outlet 300 and is used to connect the connecting channel 310 and the air guide channel 210 corresponding to the return air outlet 300;

[0078] The partition mechanism 500 is disposed between the static pressure chambers 120 corresponding to the two drying chambers 110 .

[0079] The drying room 100 has two drying chambers 110 which can be controlled separately. The hot air generated by the heating system of the heat pump unit 200 is introduced into the drying chamber 110 for drying. The evaporated moisture flows with the air through the return air port 300 and flows into the heat pump unit 200. After the moisture is removed by the dehumidification system of the heat pump unit 200, it enters the drying chamber 110 again through the heating system. The return air port 300 is connected to the connecting channel 310 and the air guide channel 210. The connection between the return air port 300 and the connecting channel 310 and the air guide channel 210 is controlled by the regulating mechanism 400. The air between the two drying chambers 110 can be exchanged by the regulating mechanism 400. When the two drying chambers 110 are dried in turn, hot air exists in one of the drying chambers 110 that has completed drying, and cold air exists in the other drying chamber 110 that has not yet been dried. After exchanging the air in the two drying chambers 110, the drying chambers that have completed drying can be sandwiched. The temperature in the drying chamber 110 is lowered to facilitate the quick removal of the items in the drying chamber 110, and the other drying chamber 110 can be quickly heated to a stable drying temperature.

When the hot air enters the cold drying chamber 110, the heating system and dehumidification system of the heat pump unit 200 corresponding to the drying chamber 110 are worked. The hot air generated by the heat pump unit 200 first enters the static pressure chamber 120, and then circulates through the connecting hole 121 between the static pressure chamber 120 and the drying chamber 110. The connection between the two static pressure chambers 120 is controlled by the partition mechanism 500. The static pressure chamber 120 is connected to the drying chamber 110 through the connecting hole 121. Compared with the heat exchange structure, the direct exchange of air in the two drying chambers 110 has a larger temperature change amplitude.

[0117] Embodiment 3:

[0118] As Figure 2 、 Figure 3 shown, the embodiment of the present application provides a drying device for casting production. In addition to including the above technical features, further, the partition mechanism 500 includes:

[0119] A partition member 510, arranged between two static pressure chambers 120;

[0120] A movable baffle 520, slidably connected in the static pressure chamber 120 and corresponding to the communication hole 121;

[0121] A threaded rod 530, installed in the static pressure chamber 120 and connected to the movable baffle 520, and the threaded rod 530 is driven by a motor;

[0122] The transmission rod 540 is installed in the static pressure chamber 120, and the transmission rod 540, the threaded rod 530, and the partition member 510 are connected through gears.

[0123] When only one drying chamber 110 is used for drying, the working drying chamber 110 can be controlled to be connected to two heat pump units 200, and the movable baffle 520 is controlled to move by the threaded rod 530 to separate the non-working drying chamber 110 from the corresponding static pressure chamber 120. Although the return air outlet 300 corresponding to the non-working drying chamber 110 is still connected to the heat pump unit 200, the air in the drying chamber 110 cannot circulate and air circulation cannot be performed. When the threaded rod 530 rotates, the transmission rod 540 The transmission causes the partition member 510 to rotate, and the movable baffle 520 can move to three positions, one of which separates the drying chamber 110 from the corresponding static pressure chamber 120, and the other two positions keep the drying chamber 110 connected to the corresponding static pressure chamber 120. The two movable baffles 520 move at the same time, and can only control one drying chamber 110 to be disconnected from the static pressure chamber 120 at most. When both drying chambers 110 are connected to the corresponding static pressure chamber 120, the two static pressure chambers 120 are separated by the partition member 510.

[0124] Embodiment 4:

[0125] The present application also provides a method for using a drying device for casting production, the specific steps of which include:

[0126] S1, when the two drying chambers 110 are drying at the same time, the partition member 510 is controlled to separate the two static pressure chambers 120, at this time, the static pressure chamber 120 is connected with the corresponding drying chamber 110, and the regulating valve plate 420 is controlled to connect the same group of return air outlets 300 corresponding to the drying chamber 110 with the heat pump unit 200, so as to realize single-cycle drying of the drying chamber 110;

[0127] S2, when the two drying chambers 110 are drying in turn, the partition member 510 is controlled to separate the two static pressure chambers 120, and the static pressure chamber 120 is connected with the corresponding drying chamber 110. When the drying chambers 110 are drying in turn, the regulating valve plate 420 is controlled to connect the return air ports 300 of different groups corresponding to the drying chambers 110 with the heat pump unit 200, so as to realize the exchange of air in the two drying chambers 110;

[0128] S3, when only one drying chamber 110 is drying, the partition member 510 is controlled to connect the two static pressure chambers 120. At this time, the drying chamber 110 for drying is connected with the corresponding static pressure chamber 120, and the other drying chamber 110 and its corresponding static pressure chamber 120 are separated by the movable baffle 520. The regulating mechanism 400 corresponding to the drying chamber 110 for drying is controlled to connect the return air outlet 300 with the two heat pump units 200.

[0129] The two drying chambers 110 have three modes of simultaneous use, alternating use, and single use, which are controlled by the heat pump unit 200, the adjustment mechanism 400, and the partition mechanism 500. In the alternating use mode, the cold air and hot air in the two drying chambers 110 are exchanged when the drying chambers 110 work in turn, thereby reducing the storage time of the dried items in the drying chamber 110 and improving the drying efficiency. In the single use mode, two heat pump units 200 can simultaneously dry one drying chamber 110, which can greatly improve the drying speed.
