Description

Technical Field

[0001] This utility model relates to the field of galvanizing technology, and in particular to an automatic stepless frequency band control device for hydrogen peroxide. Background Technology

[0002] Zinc plating is a surface treatment technique that involves coating the surface of metals, alloys, or other materials with a layer of zinc for aesthetic purposes, rust prevention, and other functions. After passivation, dyeing, or coating with a protective agent, the zinc plating can significantly improve its protective and decorative properties.

[0003] Currently, hydrogen peroxide needs to be added to the solvent bath before galvanizing. Hydrogen peroxide can react with iron ions to generate ferric hydroxide precipitate, thereby reducing the impact of iron impurities on the coating. If insufficient hydrogen peroxide is added, it may cause problems such as barrel marks on the coating, while excessive addition may result in a matte coating or missed plating.

[0004] However, when adding hydrogen peroxide to the existing solvent tank, the timing of the addition cannot be adjusted according to the required time period due to the limited control time of the controller. It can only be adjusted within the pre-set time period of the controller. This makes the interval between hydrogen peroxide additions too long, which cannot effectively and fully utilize the hydrogen peroxide. This not only increases the amount of hydrogen peroxide used, but also fails to achieve the desired mixing effect. At the same time, hydrogen peroxide needs to be stored in a sealed environment and needs to be replenished in a timely manner as it is continuously added. The existing hydrogen peroxide addition structure lacks the functions of sealing and storing hydrogen peroxide and detecting the remaining amount. Utility Model Content

[0005] To overcome the problems of existing solvent tanks where hydrogen peroxide cannot be added at the required time due to the limited control period of the controller, and the lack of functions for sealing and storing hydrogen peroxide and detecting the remaining amount in the hydrogen peroxide addition structure.

[0006] The technical solution of this utility model is as follows: an automatic stepless frequency band control device for hydrogen peroxide, including a storage tank, a feeding pump, a feeding valve, a discharging pump, a discharging valve, a protective plate, a sealing plate, a guide rod, an alarm, a displacement sensor, and a controller; a feeding pump is provided on the right side of the storage tank, a feeding valve is provided on the right side of the feeding pump, a discharging pump is provided on the left side of the storage tank, a discharging valve is provided on the left side of the discharging pump, a protective plate is provided at the upper end of the storage tank, a sealing plate is provided on the inner side of the storage tank, a guide rod is provided at the upper end of the sealing plate, an alarm is fixedly installed at the upper end of the protective plate, a displacement sensor is fixedly installed at the lower end of the protective plate, and a controller is fixedly installed at the front of the storage tank, with a cyclic time relay installed inside the controller.

[0007] Preferably, hydrogen peroxide is stored in a sealed storage tank, and the feed pump and feed valve are controlled by a controller. At the same time, a displacement sensor monitors the position of the sealing plate to achieve timed and quantitative addition of hydrogen peroxide. An alarm is set up to promptly alert staff when the hydrogen peroxide level is low, thus preventing insufficient hydrogen peroxide from being added.

[0008] Preferably, the output end of the feeding pump is connected to the inside of the storage tank, and the input end of the feeding pump is connected to the feeding valve.

[0009] Preferably, the input end of the feed pump is connected to the inside of the storage tank, and the output end of the feed pump is connected to the feed valve through the feed pipe.

[0010] Preferably, mounting feet are fixedly installed on the lower side of the protective plate. The mounting feet are arranged in a circular array, and the lower end of the mounting feet is detachably connected to the upper end of the storage tank by bolts.

[0011] Preferably, a sealing ring is fixedly installed on the outer side of the sealing plate, the sealing plate and the inner side of the storage tank are slidably connected, and the lower end of the guide rod is fixedly connected to the sealing plate.

[0012] Preferably, a sliding sleeve is fixedly installed on the surface of the protective plate, and the upper end of the guide rod extends to the upper end of the protective plate through the sliding sleeve, with the guide rod and the inner side of the sliding sleeve being slidably connected.

[0013] Preferably, the alarm and displacement sensor are electrically connected, and the feeding pump, feeding valve, discharging pump, discharging valve and controller are electrically connected.

[0014] The beneficial effects of this utility model are:

[0015] This automatic stepless frequency band control device for hydrogen peroxide uses a cyclic time relay within the controller to easily control the feed pump and feed valve to operate cyclically at preset time intervals. When hydrogen peroxide needs to be added to the solvent tank, the feed valve opens, and the feed pump outputs hydrogen peroxide. As the hydrogen peroxide decreases, the sealing plate slides downwards. The guide rod guides the sealing plate while allowing staff to visually check its height and determine the remaining hydrogen peroxide level. The displacement sensor monitors the distance the sealing plate slides. When the hydrogen peroxide level is insufficient, the displacement sensor detects that the sealing plate is too low, and the alarm sounds, reminding staff to replenish the hydrogen peroxide in time.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of an automatic stepless frequency band control device for hydrogen peroxide, including a storage tank 1, a feeding pump 2, a feeding valve 3, a discharging pump 4, a discharging valve 5, a protective plate 6, a sealing plate 7, a guide rod 8, an alarm 9, a displacement sensor 10, and a controller 11; the feeding pump 2 is located on the right side of the storage tank 1, and the feeding valve 3 is located on the right side of the feeding pump 2; the discharging pump 4 is located on the left side of the storage tank 1, and the discharging valve 5 is located on the left side of the discharging pump 4; the protective plate 6 is located at the upper end of the storage tank 1; the sealing plate 7 is located on the inner side of the storage tank 1; the guide rod 8 is located at the upper end of the sealing plate 7; the alarm 9 is fixedly installed at the upper end of the protective plate 6; the displacement sensor 10 is fixedly installed at the lower end of the protective plate 6; and the front side of the storage tank 1... A controller 11 is fixedly installed, and the controller 11 is equipped with a cyclic time relay. The cyclic time relay is a JSS48A-S cyclic time relay with an accuracy within 0.1 seconds and an adjustable time interval of up to 99 hours, which can fully meet the current needs. This allows for stepless adjustment of the addition time and interval, greatly improving the utilization rate of hydrogen peroxide. The cyclic time relay in the controller 11 facilitates the control of the feeding pump 4 and the feeding valve 5 to work cyclically according to the preset time interval. The displacement sensor 10 monitors the distance the sealing plate 7 slides down. When the hydrogen peroxide is insufficient, the displacement sensor 10 detects that the sealing plate 7 is too low, and the alarm 9 sounds an alarm to remind the staff to replenish it in time.

[0024] Please see Figures 2-5 In this embodiment, the output end of the feeding pump 2 is connected to the inner side of the storage tank 1, the input end of the feeding pump 2 is connected to the feeding valve 3, the input end of the discharge pump 4 is connected to the inner side of the storage tank 1, and the output end of the discharge pump 4 is connected to the discharge valve 5 through a discharge pipe. Mounting feet 61 are fixedly installed on the lower side of the protective plate 6, arranged in a circular array. The lower end of the mounting feet 61 is detachably connected to the upper end of the storage tank 1 by bolts. A sealing ring is fixedly installed on the outer side of the sealing plate 7, and the sealing plate 7 is slidably connected to the inner side of the storage tank 1. The lower end of the guide rod 8 is fixedly connected to the sealing plate 7. The surface of the protective plate 6 is fixed... A sliding sleeve 62 is fixedly installed. The upper end of the guide rod 8 extends to the upper end of the protective plate 6 through the sliding sleeve 62. The guide rod 8 and the inner side of the sliding sleeve 62 are slidably connected. When hydrogen peroxide needs to be added to the solvent pool, the discharge valve 5 is opened, and the discharge pump 4 outputs hydrogen peroxide. As the hydrogen peroxide decreases, the sealing plate 7 slides downward. The guide rod 8 guides the sealing plate 7 while allowing the staff to visually check the height of the sealing plate 7 and judge the remaining amount of hydrogen peroxide. The displacement sensor 10 monitors the distance the sealing plate 7 slides down. When the remaining amount of hydrogen peroxide is insufficient, the displacement sensor 10 detects that the position of the sealing plate 7 is too low, and the alarm 9 sounds an alarm to remind the staff to replenish it in time.

[0025] Please see Figures 1-2 In this embodiment, the alarm 9 and the displacement sensor 10 are electrically connected, and the feeding pump 2, feeding valve 3, discharging pump 4, discharging valve 5 and the controller 11 are electrically connected. The cyclic time relay in the controller 11 can be used to control the discharging pump 4 and the discharging valve 5 to work cyclically according to a preset time interval. By connecting the hydrogen peroxide replenishment pipeline to the feeding valve 3, the feeding valve 3 is opened and the feeding pump 2 is controlled to work, thereby replenishing the hydrogen peroxide.

[0026] During operation, the cyclic time relay in the controller 11 facilitates the control of the feed pump 4 and feed valve 5 to work cyclically at preset time intervals. When hydrogen peroxide needs to be added to the solvent tank, the feed valve 5 opens, and the feed pump 4 outputs hydrogen peroxide. As the hydrogen peroxide decreases, the sealing plate 7 slides downwards. The guide rod 8 guides the sealing plate 7 while allowing the operator to visually check the height of the sealing plate 7 and judge the remaining hydrogen peroxide level. The displacement sensor 10 monitors the distance the sealing plate 7 slides down. When the remaining hydrogen peroxide level is insufficient, the displacement sensor 10 detects that the sealing plate 7 is too low, and the alarm 9 sounds an alarm to remind the operator to replenish it in time. By connecting the hydrogen peroxide replenishment pipeline to the feed valve 3, the feed valve 3 is opened and the feed pump 2 is controlled to work, thereby replenishing the hydrogen peroxide. Subsequently, the protective plate 6 can be removed by removing the bolts on the mounting legs 61, which facilitates the inspection and maintenance of various structures.

[0027] Through the above steps, the cyclic time relay in the controller 11 facilitates the control of the feeding pump 4 and the feeding valve 5 to work cyclically according to the preset time interval. The displacement sensor 10 monitors the distance the sealing plate 7 slides down. When the hydrogen peroxide level is insufficient, the displacement sensor 10 detects that the sealing plate 7 is too low, and the alarm 9 sounds an alarm to remind the staff to replenish it in time. This solves the problem that when adding hydrogen peroxide to the existing solvent tank, the timing of adding hydrogen peroxide cannot be limited due to the controller's control period. At the same time, the hydrogen peroxide adding structure lacks the functions of sealing and storing hydrogen peroxide and detecting the remaining amount.
