Description

Technical Field

[0001] This utility model relates to the field of zinc scale cleaning technology, specifically a zinc scale cleaning device for the top guide roller of the cooling tower in a galvanizing production line. Background Technology

[0002] Galvanized steel sheet is a metallic material made by coating ordinary steel sheet with a layer of zinc to prevent corrosion and rust. This zinc layer acts as a sacrificial protective layer; even if the surface is scratched, the zinc will oxidize before the iron, thus protecting the steel sheet underneath. China's galvanizing capacity exceeds 60 million tons per year, creating a huge demand for equipment upgrades; the market demand for zinc scale recycling equipment is expected to grow at an annual rate of 15%.

[0003] However, when the galvanizing production line switches from shutdown to production mode, due to the large temperature difference between the strip steel and the zinc liquid, zinc scale may fall off. The zinc scale remaining on the surface of the turning roller at the top of the cooling tower will fall off due to gravity, polluting the production environment and increasing equipment maintenance costs. Traditional manual cleaning is inefficient and labor-intensive. Furthermore, there are safety hazards during the operation of the steel belt, as scattered zinc sheets may enter subsequent equipment (such as tension rollers), causing scratches or quality defects in the steel belt. Utility Model Content

[0004] The purpose of this invention is to provide a zinc scale cleaning device for the top guide roller of the cooling tower in a galvanizing production line, so as to solve the problems mentioned in the background art.

A cleaning mechanism is installed inside the slider. A pressure adjustment mechanism is installed inside the bracket. A material collection trough is fixedly connected to the bottom surface of the bracket. A guide pipe is fixedly connected to the bottom of the material collection trough. A screw conveyor is fitted onto the bottom of a guide pipe. A vibrating motor is fixedly connected to one inclined side of the guide pipe. A conveying motor is fixedly connected to one end of the screw conveyor. A collection box is fitted onto the other end of the screw conveyor.

[0008] Preferably, the bottom of the collection trough is designed with an inclined structure and an inclination angle of 45°.

[0009] Preferably, the bristles of the steel brush roller are made of nylon, with a bristle length of 30-50mm and a hardness of HRC30-40.

[0010] Preferably, the material collection trough is located directly below the steel brush roller, and its width matches the width of the steel strip.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting up a cleaning mechanism and a pressure adjustment mechanism, can clean the zinc scale remaining on the surface of the steel plate, avoiding manual cleaning and thus avoiding safety hazards to workers, effectively improving the safety of cleaning zinc scale. By combining the collection trough and the screw conveyor, the fallen zinc sheets are transported to the collection box, thus preventing the cleaned zinc sheets from scattering everywhere and polluting the production environment.

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-6 As shown, a zinc scale cleaning device for the top steering roller of a cooling tower in a galvanizing production line includes a bracket 1, and there are two brackets 1. The bracket 1 has a sliding groove 2 inside, and a slider 3 is slidably connected to the surface of the sliding groove 2. A cleaning mechanism 4 is installed inside the slider 3. The cleaning mechanism 4 includes a bearing seat 41 and a steel brush roller 42. The bearing seat 41 is fixedly connected to the surface of the slider 3, and the steel brush roller 42 is rotatably connected to the inner wall of the bearing seat 41. There are two bearing seats 41 for supporting the rotation of the steel brush roller 42. The cleaning mechanism 4 also includes a variable frequency motor 43 fixedly connected to one end of the steel brush roller 42. By starting the variable frequency motor 43, the steel brush roller 42 is driven to rotate in the opposite direction to the steering roller, thereby cleaning the zinc coating on the surface of the steel plate.

[0016] The bristles of the steel brush roller 42 are made of nylon to avoid damaging the surface of the steel plate. One end of the slider 3 is fixedly connected to a support base 44, and the variable frequency motor 43 is fixedly connected to the top of the support base 44, thereby providing a support platform for the variable frequency motor 43.

[0017] It should be noted that the steel brush roller 42 is installed on the inlet side of the steering roller, maintaining a gap of 0.2 to 0.5 mm with the surface of the steering roller, and the bristle length is 30 to 50 mm with a hardness of HRC30-40. The rotating shaft at one end of the steel brush roller 42 is rotatably connected to the inner wall of the slider 3 and fixedly connected to the output shaft of the variable frequency motor 43. The variable frequency motor 43 has a power of 5.5 kW and a speed range of 100-300 rpm, and is used to achieve synchronous reverse rotation with the steering roller.

[0018] The bracket 1 is equipped with a pressure adjustment mechanism 5, which includes a spring 51 fixedly connected to the bottom of the slider 3. The spring 51 is fixedly connected to the bottom of the inner cavity of the sliding groove 2. Under this action, when the steel brush roller 42 is subjected to the pressure of the steel plate, the steel brush roller 42 drives the slider 3 to slide down along the surface of the sliding groove 2. The slider 3 drives the spring 51 to compress. However, under the elastic action of the spring 51, the bristles on the surface of the steel brush roller 42 are in continuous contact with the steel plate, thereby achieving the effect of continuous cleaning of the steel plate surface.

[0019] It should be noted that the elasticity of the spring 51 is greater than the weight of the cleaning mechanism 4 and the slider 3, so as to avoid the steel brush roller 42 being unable to contact the surface of the steel plate during operation due to the excessive weight of the cleaning mechanism 4 and the slider 3.

[0020] Based on the above implementation scheme, the pressure regulating mechanism 5 also includes a track groove 52 opened inside the bracket 1, and a sliding column 53 is fixedly connected to the bottom of the slider 3. The sliding column 53 slides on the surface of the track groove 52. There are two track grooves 52 and two sliding columns 53, which provide guidance for the spring 51 and prevent the spring 51 from becoming unstable and unbalanced, thereby making the device operate more stably.

[0021] A collection trough 6 is fixedly connected to the bottom surface of the support 1. The bottom of the collection trough 6 is designed with an inclined structure and an inclination angle of 45°. The collection trough 6 is used to temporarily collect the zinc sheet that falls off the steel plate cleaned by the steel brush roller 42. A guide pipe 7 is fixedly connected to the bottom of the collection trough 6.

[0022] It should be noted that the material collection trough 6 is located directly below the steel brush roller 42, and its width matches the width of the steel strip.

[0023] A screw conveyor 8 is fitted to the bottom of the guide pipe 7. Through the cooperation of the collection trough 6 and the guide pipe 7, zinc sheets can be guided into the interior of the screw conveyor 8. A vibration motor 9 is fixedly connected to one inclined side of the guide pipe 7. The vibration motor 9 is used to vibrate the collection trough 6. The zinc sheets at the bottom of the collection trough 6 fall into the screw conveyor 8 due to the vibration, thereby preventing the zinc sheets from accumulating at the bottom of the collection trough 6 and affecting the working efficiency.

[0024] One end of the screw conveyor 8 is fixedly connected to a conveyor motor 10, which drives the screw conveyor 8 to rotate. The other end of the screw conveyor 8 is fitted with a collection box 11. When the conveyor motor 10 is started, the screw conveyor 8 conveys the zinc sheet inside to the inside of the collection box 11, thus completing the collection of the zinc sheet.

[0025] The top of the collection box 11 is equipped with a discharge valve 12 with a capacity of 50-100L. The function of the discharge valve 12 is to discharge the zinc sheet piled up inside the collection box 11.

[0026] A rubber pad 13 is fixedly connected to the top of the sliding groove 2. The rubber pad 13 is used to buffer the slider 3 and prevent the slider 3 from being worn when resetting.

[0027] It should be noted that during the above-mentioned operation, when the production line is switched from shutdown to startup, the variable frequency motor 43, the vibration motor 9, and the conveyor motor 10 will start automatically and stop after running for 20 minutes.

[0028] It is worth noting that the technical features such as the variable frequency motor 43, the vibration motor 9, and the conveyor motor 10 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0029] Working principle: First, install the device on the production line, then start the variable frequency motor 43, vibrating motor 9, and conveying motor 10. Next, start the production line. Then, the variable frequency motor 43 drives the steel brush roller 42 to rotate. The steel plate slides over the surface of the steel brush roller 42. Under the gravity of the steel plate, the steel brush roller 42 moves downward, and at the same time, the slider 3 slides downward along the surface of the sliding groove 2, causing the slider 3 to compress the spring 51. Under the elastic action of the spring 51, the bristles on the surface of the steel brush roller 42 keep in contact with the surface of the steel plate, thus completing the work of cleaning the zinc scale on the surface of the steel plate. The cleaned zinc scale falls into the inside of the collection trough 6 and is guided into the inside of the screw conveyor 8 through the guide pipe 7. At the same time, the vibrating motor 9 vibrates the collection trough 6 to prevent the zinc scale from accumulating at the bottom of the collection trough 6. The conveying motor 10 drives the screw conveyor 8 to rotate, thus transporting the zinc scale into the inside of the collection box 11 to complete the collection of zinc scale. After running for 20 minutes, stop the device, open the discharge valve 12, and clean the zinc scale in the collection box 11.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
