Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides an implementation scheme: In the application of modern leather dehumidifiers, leather dehumidifiers often use a single-pipe air supply. By spraying atomized steam toward the leather, the steam is used to humidify the passing leather and soften it. However, in this simple dehumidifier structure, the pipe opening cannot evenly supply air to the leather, and excess steam is prone to overflow, resulting in a waste of steam and energy.

[0021] To address the aforementioned issues, this application discloses a leather rehydration machine. The equipment uses a rehydration machine as a steam generator. Specifically, a main air supply pipe 3 extends from one side of the main body 1 of the rehydration machine. Steam is extracted from the main body 1 of the rehydration machine through the main air supply pipe 3 and then transported to the leather processing side. A rehydration operation frame 2 is provided on one side of the main body 1 of the rehydration machine. The leather passes through the upper part of the rehydration operation frame 2 in a unidirectional manner. Specifically, a diversion air supply seat 4 is provided on the main air supply pipe 3 of the rehydration machine shell of the rehydration operation frame 2. The diversion air supply seat 4 is installed on the rehydration machine frame. The diversion method of the diversion air supply seat 4 makes the steam sprayed more evenly.

[0022] According to the instruction manual Figure 1-3 It can be seen that the aforementioned air distribution seat 4 has several exhaust ports 5 integrally protruding from it, with the exhaust ports 5 opening upwards. The air distribution seat 4 is a trapezoidal plate, and a distribution groove 6 is provided on the air distribution seat 4, which communicates with the exhaust ports 5. The inlet of the distribution groove 6 is connected to the end of the main air supply pipe 3. Through the inlet of the distribution groove 6, the steam entering from the main air intake pipe is distributed to the exhaust ports 5 by the distribution effect of the distribution groove 6. The upward-facing exhaust ports 5 are used to steam-moisten the passing leather, which facilitates subsequent processing of the leather. The arrangement of 4 can divert the flow and increase the uniformity of moisture reabsorption. At the same time, the steam outlet can be made to fit the leather more closely through the diverting air supply seat 4, which can improve the moisture reabsorption effect. In order to recover and reuse excess steam, a pair of height adjusters 10 are set on both sides of the moisture reabsorption operation frame 2. The top of the pair of height adjusters 10 is connected to the guide hood 11. The guide hood 11 has the effect of guiding the steam. The guide hood 11 is equipped with a steam recovery device. The steam recovery device can use negative pressure to extract the steam from the guide hood 11 for easy recovery and reuse.

[0023] According to the instruction manual Figure 1-3It can be seen that the re-moistening operation frame 2 is a rectangular frame, the re-moistening operation frame 2 is equipped with a conveyor belt 7, the conveyor belt 7 is provided with a number of ventilation holes 8 in a matrix, the re-moistening operation frame 2 is provided with a number of through grooves 9 evenly, and the two sides of the diversion air supply seat 4 are connected to the two sides of the through grooves 9.

[0024] In the specific implementation process, the leather is carried by the conveyor belt 7 and passes through the diversion air supply seat 4 in one direction. The air vent 8 is used for the passage of steam. The diversion air supply seat 4 is arranged on the passage groove 9, which is convenient for replacement and can also allow the whole body to pass through.

[0025] As a preferred embodiment, the steam recovery device further comprises a guide pipe 12 and a negative pressure fan 13. The guide pipe 12 is connected to the top of the guide shroud 11, and the negative pressure fan 13 is connected to the end of the guide pipe 12. A heat exchanger 14 is installed inside the guide pipe 12. The negative pressure suction generated by the negative pressure fan 13, and the guide shroud 11 corresponding to the steam outlet of the leather and the dehumidifier, when the steam passes through the leather, the excess steam enters the guide pipe 12 from the guide shroud 11. The heat exchanger 14 is then installed in the guide pipe 12 to recover the heat from the steam.

[0026] As a preferred option, a preheating pipe 15 is connected to the heat exchanger 14. The preheating pipe 15 is connected to the rehumidifier body 1. The rehumidifier body 1 consists of a rotary fan connected to a pressure tank and a motor that drives the pressure tank. The water inlet of the rehumidifier body 1 is connected to the preheating pipe 15. When producing steam, the water entering the preheating pipe 15 is heated by the heat exchanger 14 to increase the initial temperature, thereby reducing the heat requirement for steam production.

[0027] As a preferred option, the outlet of the rotary blower is further connected to the main air supply pipeline 3 to output steam to the branch air supply seat 4.

A diversion air supply seat 4 is installed on the air outlet of the rehydration machine. Under the guiding and diverting effect of the diversion air supply seat 4, the uniformity and effect of rehydration are improved. Furthermore, a steam recovery guide device is installed on the diversion air supply seat 4, which can recover the heat in the steam and improve the heat utilization rate.
