When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0056] Please refer to Figure 1 and Figure 2 , the present utility model provides a device for preparing acid for neutralization in a mercerizing machine, including a support frame 22, a mixing tank 1, a chemical agent delivery pipe 2, a first pump body 3, a first valve body 4, a circulating infusion pipe 5, a pH sensor 6, a second pump body 7, and a controller.

[0057] Specifically, the mixing tank 1 is arranged on the support frame 22, and a stirring device with stirring blades (the stirring blades are driven by a motor) is arranged therein to mix water and acidic chemical agents to prepare the acid for neutralizing fabrics.

[0058] The output end of the chemical agent delivery pipe 2 is located above the mixing tank 1. The first pump body 3 can be an acid-resistant pump, and its input end and output end are simultaneously connected to the chemical agent delivery pipe 2. Through the first pump body 3, the acidic chemical agent in the chemical agent barrel 21 can be transported to the mixing tank 1 through the chemical agent delivery pipe 2.

[0059] The first valve body 4 is arranged on the chemical agent delivery pipe 2, and the first valve body 4 is located downstream of the first pump body 3 (it can be arranged on the pipe body close to the output end of the chemical agent delivery pipe 2). The first valve body 4 is an electric valve body, and it is electrically connected to the controller, so that the opening degree of the first valve body 4 can be controlled by the controller to realize the adjustment of the feeding speed of the acidic chemical agent.

[0060] The input end of the circulating infusion pipe 5 is connected to the bottom of the mixing tank 1, and the output end of the circulating infusion pipe 5 is located above the mixing tank 1. The input end and output end of the pH sensor 6 are simultaneously connected to the circulating infusion pipe 5. The input end and output end of the second pump body 7 are both connected to the circulating infusion pipe 5. The controller is electrically connected to the first pump body 3, the pH sensor 6, and the second pump body 7.

[0061] When the second pump body 7 is working, it pumps out the acid solution in the mixing tank 1 from the bottom of the mixing tank 1 and then pumps it back up into the mixing tank 1. Since the input end and the output end of the pH sensor 6 are both connected to the circulating infusion tube 5, when the acid solution in the mixing tank 1 flows in the circulating infusion tube 5, the pH value of the acid solution can be monitored by the pH sensor 6. When the pH sensor 6 monitors that the pH value of the acid solution in the circulating infusion tube 5 meets the requirement for neutralizing the fabric, the controller controls the first pump body 3 and the first valve body 4 to stop the first pump body 3 from working and close the first valve body 4 at the same time, and no longer continue to add acid agent into the mixing tank 1. Thus, even if the pH value of the water body added into the mixing tank 1 each time is different, the pH value of the acid solution in the mixing tank 1 can be maintained within a reasonable range and can meet the requirement for washing and neutralizing the fabric.

[0062] After the acidic agent is added into the mixing tank 1, since it takes a certain amount of time for the acidic agent to be evenly mixed with the water body, even if the pH sensor 6 monitors that the pH value of the acid solution in the circulating infusion tube 5 meets the requirement for neutralizing the fabric, the pH value of the acid solution will still decrease during the continuous stirring and mixing process. Considering the above situation, in actual production, the conditions for stopping the first pump body 3 from working and closing the first valve body 4, that is, the pH value that the acid solution in the circulating infusion tube 5 needs to reach, can be set to a slightly higher value (this value is an empirical value). In this way, when the first pump body 3 stops working and the first valve body 4 is closed, even if the pH value of the acid solution in the mixing tank 1 continues to drop, the pH value of the acid solution can be ensured to be maintained within a reasonable range.

[0063] As Figure 1 and Figure 2 shown, in a preferred embodiment of the present invention, the device for preparing acid for mercerizing machine neutralization further includes a first liquid outlet pipe 8, a second valve body 9 and a third valve body 10.

[0064] Among them, the first liquid outlet pipe 8 is connected to the bottom of the mixing tank 1; the second valve body 9 can also be an electric valve body electrically connected to the controller and is arranged on the first liquid outlet pipe 8. After the acid for mercerizing machine neutralization is prepared, the second valve body 9 in the closed state can be opened, so that the acid solution in the mixing tank 1 is transported to the acid tank of the mercerizing machine through the first liquid outlet pipe 8 under the action of the pump body. The first liquid outlet pipe 8 can be composed of multiple sections of pipes spliced together (including metal pipes and flexible conveying pipes).

[0065] When necessary, a tank for storing the acid for neutralization can be dug under the workshop floor, and the acid solution in the mixing tank 1 can be first transported to the tank through the first liquid outlet pipe 8 for storage and then transported to the acid tank of the mercerizing machine. Since the tank can pre-store a large amount of acid for neutralization, it can meet the water washing and neutralization requirements of continuously produced fabrics.

[0066] As Figure 1 、Figure 3 and Figure 4 As shown in and

[0067] , in a preferred embodiment of the present utility model, the device for preparing the acid for neutralization in the mercerizing machine further includes a liquid storage tank 11, a liquid inlet pipe 12, a second liquid outlet pipe 13, and a third pump body 14.

[0067] Among them, the liquid storage tank 11 is arranged on the support frame 22 and is located below the mixing tank 1; the output end of the liquid inlet pipe 12 is located above the liquid storage tank 11, and it can transport the waste alkali liquid generated by fabric alkali washing into the liquid storage tank 11, thereby realizing the recycling of the waste alkali liquid.

[0068] The input end of the second liquid outlet pipe 13 is connected to the bottom of the liquid storage tank 11, and both the input end and the output end of the third pump body 14 are connected to the second liquid outlet pipe 13. When the third pump body 14 works, the recycled waste alkali liquid can be transported to the mixing tank 1 through the second liquid outlet pipe 13 for preparing the acid for neutralization (it is found in actual production that when the pH value of the acid for neutralization is about 5, the effect of fabric water washing and neutralization is the best, and the quality of the fabric after water washing and neutralization can be maintained stable), reducing the waste of water resources.

[0069] As Figure 5 shown in and

[0070] , in a preferred embodiment of the present utility model, the device for preparing the acid for neutralization in the mercerizing machine further includes a filter screen assembly 15.

[0070] The filter screen assembly 15 is detachably arranged in the liquid storage tank 11, and the filter screen assembly 15 is located below the output end of the liquid inlet pipe 12 to filter the sediment in the waste alkali liquid, thereby preventing the sediment from entering the acid tank of the mercerizing machine and avoiding quality problems of the fabric.

[0071] As Figure 1 and Figure 3 shown in and

[0072] , in a preferred embodiment of the present utility model, the device for preparing the acid for neutralization in the mercerizing machine further includes a weight sensor 16 and a fourth valve body 17. The weight sensor 16 is arranged on the support frame 22 and is connected to the tank wall of the mixing tank 1, so as to monitor the weight of the mixing tank 1; in order to enable the monitoring result of the weight sensor 16 to be fed back to the controller, the weight sensor 16 is electrically connected to the controller. The fourth valve body 17 is arranged on the second liquid outlet pipe 13 and is electrically connected to the controller, and the fourth valve body 17 is located downstream of the third pump body 14.

[0072] By monitoring the weight of the mixing tank 1 through the weight sensor 16, the addition amount of the waste alkali liquid in the mixing tank 1 can be controlled. During the process of adding the waste alkali liquid, when the weight sensor 16 monitors that the weight change of the mixing tank 1 meets the requirement of the addition amount of the waste alkali liquid (within a certain weight range), the controller can automatically control the third pump body 14 and the fourth valve body 17 based on the monitoring result, so that the third pump body 14 stops working, and at the same time the fourth valve body 17 closes, and no longer continues to add the waste alkali liquid into the mixing tank 1.

[0073] As Figure 4 shown, in a preferred embodiment of the present invention, the device for preparing the acid for neutralization in the mercerizing machine further includes an emptying pipe 18 and a fifth valve body 19. The emptying pipe 18 is located below the liquid storage tank 11, and the emptying pipe 18 is connected to the second liquid outlet pipe 13. The fifth valve body 19 is arranged on the emptying pipe 18, and it can be a manually opened valve body.

[0074] The fifth valve body 19 always remains closed when there is waste alkali liquid stored in the liquid storage tank 11, and the fifth valve body 19 will only open when it is necessary to clean the liquid storage tank 11.

[0075] As Figure 3 shown, in a preferred embodiment of the present invention, an infusion hose 20 is sleeved on the input end of the chemical agent delivery pipe 2, and the infusion hose 20 is located inside the chemical agent barrel 21. Since the infusion hose 20 can be rolled up and placed elsewhere, when workers need to carry the chemical agent barrel 21, the setting of the conveying pipeline will not affect the carrying of the chemical agent barrel 21.

[0076] As Figure 6 shown, in a preferred embodiment of the present invention, the pH sensor 6 includes a cylinder 61 and a detection electrode 62. The setting of the pore channel 611 enables the acid liquid to slowly flow upward after flowing into the pH sensor 6, ensuring that the detection electrode 62 accurately monitors the pH value of the acid liquid.

[0077] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
