Description

Technical Field

[0001] The utility model relates to the technical field of heating steel strip leveling liquid, in particular to a constant temperature device for heating steel strip leveling liquid. Background Art

[0002] When flattening the steel strip, it is often necessary to add flattening liquid. When the steel strip enters the inlet of the flattening equipment, the diluted flattening liquid is sent to the sprayer, and then atomized and sprayed onto the upper and lower surfaces of the steel strip to lubricate and clean the surface of the steel strip.

[0003] In order to ensure the fluidity and lubrication effect of the leveling liquid, the diluted leveling liquid needs to be heated to a specified temperature and kept at a constant temperature, and then the leveling liquid is sent to the sprayer by a liquid pump. When continuously leveling a long length of steel strip, more leveling liquid is required. Therefore, the leveling liquid needs to be added multiple times during the process. However, the existing leveling liquid heating equipment cannot keep the original leveling liquid at a constant temperature when adding new leveling liquid for dilution, resulting in large temperature fluctuations, affecting the normal leveling process, and needs to be improved. Utility Model Content

[0012] Wherein, a limiting ring is integrally arranged on the edge of the plunger top plate, and the outer diameter of the limiting ring is larger than the inner diameter of the through hole.

[0013] Among them, a rectangular groove penetrated by a lifting rod is provided on the cross beam, and a limit pin is radially arranged in the lifting rod.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0017] Combine the following Figure 1 The technical solution of the utility model is further illustrated by specific embodiments.

[0018] like Figure 1 The steel strip leveling liquid heating and constant temperature device shown comprises: a plunger 10, a constant temperature box 1 and a heating and dilution box 2. A sealing plate 9 is arranged on the top of the constant temperature box 1 for heat preservation. The heating and dilution boxes 2 are arranged on the sealing plate 9 at intervals. The number of the heating and dilution boxes is at least 2. In this embodiment, two heating and dilution boxes 2 are used to alternately dilute, add and heat the leveling liquid.

[0019] A first heating pipe 11 extending into the thermostatic box 1 is provided on the side of the thermostatic box 1 to heat and insulate the leveling liquid in the thermostatic box 1 to ensure the constant temperature of the leveling liquid. An external liquid pump is connected to one side of the thermostatic box 1 to continuously provide leveling liquid when the steel strip is leveled to ensure the smooth progress of the leveling process.

[0020] In this embodiment, the sealing plate 9 is provided with a first temperature switch 8 extending downward into the thermostatic box 1 for detecting the temperature of the leveling liquid in the thermostatic box 1. The first temperature switch 8 is linearly connected to the first heating tube 11. When the specified temperature is reached, the first heating tube 11 is powered off, which has good energy saving performance. After the temperature drops, the power supply to the first heating tube 11 is restored to reduce the fluctuation of the leveling liquid temperature in the thermostatic box 1.

[0021] A second heating tube 12 extending to the inside of the heating and dilution box 2 is provided on the side of the heating and dilution box 2, which can heat the leveling liquid in the heating and dilution box 2. A through hole 16 penetrating the sealing plate 9 is provided at the bottom of the constant temperature box 2, and the plunger 10 is arranged in the through hole 16. A limiting ring 15 is integrally provided on the edge of the top plate of the plunger 10, and the outer diameter of the limiting ring 15 is larger than the inner diameter of the through hole 16. The limiting ring 15 is used to limit the downward movement of the plunger 10 in the through hole 16, so as to ensure the blocking of the through hole 16.

[0022] In this embodiment, a sealing ring 14 located in the through hole 16 is provided on the outer circle of the plunger 10 to block and seal the through hole 16, thereby preventing the unheated leveling liquid in the heating dilution box 2 from entering the constant temperature box 1 below, which is beneficial to maintaining the temperature of the leveling liquid in the constant temperature box 1 constant.

[0023] A water channel 13 located below the sealing ring 14 is provided in the bottom of the plunger 10, a crossbeam 3 located above the plunger 10 is provided on the top of the heating and dilution box 2, and a lifting rod 5 is provided on the top of the plunger 10 to penetrate the crossbeam 3 upward, and the plunger 10 can be moved up and down by the lifting rod 5. The water channel 13 is a straight groove or a cross groove. After the plunger 10 rises, the heated leveling liquid in the heating and dilution box 2 enters the thermostatic box 1 below through the water channel 13 to replenish the leveling liquid in the thermostatic box 1.

[0024] In this embodiment, the crossbeam 3 is provided with a second temperature switch 7 extending downward to the interior of the heating and dilution box 2 to detect the temperature of the leveling liquid in the heating and dilution box 2. The second temperature switch 7 is connected to the second heating pipeline 12, and the power supply of the second heating pipeline 12 is turned off when the temperature of the leveling liquid in the heating and dilution box 2 reaches the standard, which has good energy saving performance.

[0025] A rectangular groove 4 penetrated by a lifting rod 5 is provided on the cross beam 3, and a limit pin 6 is radially provided in the lifting rod 5. The length of the limit pin 6 is greater than the width of the rectangular groove and less than the length of the rectangular groove 4. When the limit pin on the right side rises to the top surface of the cross beam 3 along with the lifting rod, the top of the water groove is located above the through hole 16. At this time, the lifting rod is twisted to make the limit pin rotate onto the cross beam 3, and the lifting rod 5 is limited to move downward, thereby releasing the blockage of the through hole 16 by the plunger 10, ensuring that the heated leveling liquid in the heating and dilution box 2 on the right side enters the constant temperature box 1 below through the water groove 13.

[0026] The leveling liquid in the thermostatic box 1 can be pre-diluted and heated by the heating dilution box 2, so that the temperature of the leveling liquid entering the thermostatic box 1 remains constant, meeting the demand for leveling liquid during the continuous production of the steel strip.

[0027] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
