Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a boiler with a descaling function. Background Art

[0002] The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. A boiler consists of two parts: a pot and a furnace. The hot water or steam produced in a boiler can directly provide the required thermal energy, or it can be converted into mechanical energy through a steam power device, or it can be converted into electrical energy through a generator. After a long period of boiling, the calcium salt and magnesium salt in the water will form scale in the boiler, greatly reducing the thermal conductivity of the boiler. This not only wastes fuel, but also causes local overheating of the pipeline. When the temperature exceeds the allowable temperature of the metal, the boiler pipeline will be deformed or damaged, and in severe cases, it will cause an explosion.

[0003] Existing boiler equipment does not have an automatic descaling function. When the pot body needs to be descaled, manual descaling is usually used, which is time-consuming and labor-intensive, with low cleaning efficiency and poor cleaning effect. Although some boilers have an automatic descaling function, there are still certain usage defects. For example, the utility model patent with authorization announcement number CN 215638036 U (hereinafter referred to as comparative document D1) discloses a boiler with an automatic descaling function. As a prior art, the device uses the saw teeth on the first fixed plate to scrape the pot body to remove dirt when in use, but there is a certain gap between the saw teeth and the inner wall of the pot body, which will result in incomplete scraping, and there is no squeezing force between the saw teeth and the inner wall of the pot body, resulting in poor scraping effect. In addition, the two second support rods arranged on the top of the pot body will cause the overall structure of the device to be larger, occupy too much space resources, and be inconvenient to move; for this reason, we design a boiler with a descaling function to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a boiler with a descaling function to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A boiler with a descaling function comprises a pot body arranged on the top of a combustion furnace, a water injection pipe is provided on the upper part of the outer surface of the pot body, a drainage pipe is provided on the lower part of the outer surface of the pot body, fixed seats are symmetrically provided on the left and right side surfaces of the pot body, an electric push rod is fixedly inserted at the middle position of the bottom of the fixed seat, the output end of the electric push rod vertically upward penetrates the fixed seat and is connected to a support plate, a cross plate is fixed between the two support plates, a motor is provided at the middle position of the top of the cross plate, the output shaft of the motor penetrates the cross plate and is connected to a rotating rod, the other end of the rotating rod penetrates into the inside of the pot body and is connected to a rotating plate, a plurality of telescopic columns are symmetrically provided on the left and right side surfaces of the rotating plate, the other end of the telescopic column is connected to a brush plate, a plurality of bristles are evenly provided on the other side surface of the brush plate, a spring is sleeved on the outside of the telescopic column, one end of the spring is connected to the rotating plate, and the other end is connected to the brush plate.

[0010] As a further preferred solution of the utility model: the horizontal plate is located directly above the top of the pot body.

[0011] As a further preferred solution of the utility model: the length of the rotating plate is smaller than the inner diameter of the pot body.

[0012] As a further preferred solution of the utility model: the two sliding rods are symmetrically distributed on the front and rear sides of the electric push rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the device is performing the descaling operation, the motor and the two electric push rods are started at the same time. The output end of the motor drives the rotating plate to rotate through the rotating rod, and then drives the brush plate together with the bristles on its surface to rotate, so as to clean the dirt on the inner wall of the pot body. Due to the cooperation of the telescopic column and the spring, and the spring is always in a compressed state, under the action of the spring elastic force, the bristles always have a certain squeezing force on the inner wall of the pot body. When the bristles move, they have a very good thorough wiping and cleaning effect, and the scraping effect is good. At the same time, the electric push rod can drive the rotating plate to move up and down reciprocatingly, which can drive the bristles to move up and down reciprocatingly, and comprehensively clean the inner wall of the pot body.

[0015] 2. This device is simple and convenient to operate, with good effect, through the cooperation of the fixed seat, electric push rod, support plate and cross plate. In addition, the fixed seat and the electric push rod are arranged on the left and right sides of the pot body, which greatly reduces the overall structural size of the device, does not occupy too much space resources, facilitates the movement of the device, and improves convenience, which is worthy of promotion.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-4In the embodiment of the utility model, a boiler with a descaling function includes a pot body 1 arranged on the top of the combustion furnace, a water injection pipe is arranged on the upper part of the outer surface of the pot body 1, a drainage pipe is arranged on the lower part of the outer surface of the pot body 1, and a fixing seat 2 is symmetrically arranged on the left and right sides of the pot body 1. The top surface of the fixing seat 2 is coplanar with the top surface of the pot body 1, and an electric push rod 8 is fixedly inserted in the middle position of the bottom of the fixing seat 2. The output end of the electric push rod 8 vertically penetrates the fixing seat 2 upward and is connected to a support plate 3. A horizontal plate 4 is fixed between the two support plates 3, and the horizontal plate 4 is located directly above the top of the pot body 1. A motor 5 is provided in the middle position at the top of the horizontal plate 4, and the output shaft of the motor 5 passes through the horizontal plate 4 and is connected to a rotating rod 6. The other end of the rotating rod 6 passes through the inside of the pot body 1 and is connected to a rotating plate 9. The length of the rotating plate 9 is smaller than the inner diameter of the pot body 1. A plurality of telescopic columns 10 are symmetrically provided on the left and right side surfaces of the rotating plate 9. A brush plate 12 is connected to the other end of the telescopic column 10. A plurality of bristles 13 are evenly provided on the other side surface of the brush plate 12. A spring 11 is sleeved on the outside of the telescopic column 10, and one end of the spring 11 is connected to the rotating plate 9, and the other end is connected to the brush plate 12.

[0023] Two through holes 14 are provided on the top of the fixing seat 2, and sliding rods 7 corresponding to them are slidably inserted in the through holes 14. The two sliding rods 7 are symmetrically distributed on the front and rear sides of the electric push rod 8, and the top of the sliding rod 7 is fixedly connected to the bottom of the support plate 3; when the electric push rod 8 is started, the electric push rod 8 can drive the support plate 3 together with the cross plate 4 and the motor 5 to move upward or downward. The design of multiple sliding rods 7 being slidably inserted in the through holes 14 can improve the stability of the up and down movement of the motor 5, which is helpful for the brush 13 to clean the inner wall of the pot body 1.

[0024] The brush plate 12 is an arc-shaped plate matched with the inner wall of the pot body 1. This design can ensure that the multiple bristles 13 are evenly squeezed with the inner wall of the pot body 1, that is, the wiping and cleaning effect is guaranteed, and the practicality of the device is improved.

[0025] The design of the combustion furnace in this device is the same as the prior art and no improvements have been made thereto, so it will not be elaborated here and is not shown in the figure. For details, please refer to comparative document D1.

[0026] It is worth noting that the telescopic columns 10 on the left and right sides of the rotating plate 9 are always in a retracted state, that is, the spring 11 is always in a compressed state. Therefore, under the elastic force of the spring 11, there is a thrust on the brush plate 12, which can ensure that the bristles 13 always have a certain squeezing force on the inner wall of the pot body 1, thereby ensuring the cleaning effect of wiping dirt.

[0027] Specifically, when the device is performing a descaling operation, the motor 5 and the two electric push rods 8 are started at the same time. The output end of the motor 5 drives the rotating plate 9 to rotate through the rotating rod 6, and then drives the brush plate 12 together with the bristles 13 on its surface to rotate, so as to clean the dirt on the inner wall of the pot body 1. Due to the cooperation of the telescopic column 10 and the spring 11, and the spring 11 is always in a compressed state, under the action of the elastic force of the spring 11, the bristles 13 always have a certain squeezing force on the inner wall of the pot body 1. When the bristles 13 move, they have a very good thorough wiping and cleaning effect, and the scraping effect is good. At the same time, the electric push rod 8 can drive the rotating plate 9 to move back and forth up and down, which can drive the bristles 13 to move back and forth up and down, and comprehensively clean the inner wall of the pot body 1.

[0028] Through the cooperation of the fixed seat 2, the electric push rod 8, the support plate 3 and the cross plate 4, the fixed seat 2 and the electric push rod 8 are arranged on the left and right sides of the pot body 1, which greatly reduces the overall structural size of the device, does not occupy too much space resources, facilitates the movement of the device, improves convenience, and is worthy of promotion.

[0029] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
