Description

Technical Field

[0001] This application relates to the technical field of slurry heating equipment, and particularly relates to an automatic slag discharging and conveying system for a tank body and an automatic slag discharging device for a tank body. Background Art

[0002] A central stirrer is equipped inside a slurry heating tank. The bottom of the slurry heating tank is conical in shape. The bottom slag discharging valve of the slurry heating tank is a manual ball valve. The discharging port of the slurry heating tank is arranged at a position lower than the bottom of the cone. The bottom of the cone of the slurry heating tank is a sand storage area. The discharging port of the slurry heating tank is arranged at a position lower than the bottom of the cone. The centrifuge feed pump will pump the sand deposited at the bottom of the cone of the slurry heating tank into the three-phase centrifuge, accelerating the wear of the accelerating pump and the three-phase centrifuge, and even causing blockage of the pipeline of the slurry heating tank. In order to ensure the oil extraction rate of the slurry in the slurry heating tank, reduce the grease viscosity, and facilitate grease separation, the temperature of the heating component of the slurry heating tank is about 80°C during operation. Therefore, sand cannot be discharged from the heating component during the operation of the slurry heating tank. So, every day, the slag discharging valve at the bottom of the heating component can only be manually opened to discharge sand before the slurry heating tank works, and only the sediment below the discharging port of the heating component can be discharged. Each time sand is discharged, part of the slurry will fall from the slag discharging valve together with the sand, and there is a risk of scalding due to the high temperature. At the same time, part of the grit and slurry will splash to the ground, which will also pollute the environment where the slurry heating tank is located.

[0003] The slag discharging of the existing slurry heating tank mainly relies on manual labor. During the intermittent operation of the slurry heating tank, sand is discharged from the slurry heating tank in a batch by stopping the machine, and there is a lot of manual intervention, which is time-consuming and laborious. Content of the Utility Model

[0004] This application provides an automatic slag discharging and conveying system for a tank body and an automatic slag discharging device for a tank body, which are used to solve the technical problems that the existing slurry heating tank cannot discharge sand during operation, and manual sand discharging is time-consuming, laborious, endangers personal safety and blocks pipelines.

[0029] The embodiments of the present application provide an automatic slag discharging and conveying system for a tank body and an automatic slag discharging device for a tank body, which are used to solve the technical problems that the existing slurry heating tank cannot discharge sand during operation, and manual sand discharging is time-consuming, laborious, endangers personal safety, and blocks pipelines. In this embodiment, the automatic slag discharging and conveying system for the tank body and the automatic slag discharging device for the tank body can be applied not only to mixing and stirring equipment for mixed mud such as sand and cement, but also to production equipment that requires slurry processing products. In this embodiment, the automatic slag discharging and conveying system for the tank body and the automatic slag discharging device for the tank body are described by taking the sand and cement mixing and stirring equipment as an example.

[0030] Embodiment 1:

[0031] Figure 1 It is a schematic structural diagram of the automatic slag discharging device for the tank body described in the embodiments of the present application.

[0032] As Figure 1 shown, the embodiments of the present application provide an automatic slag discharging device for a tank body, including a tank body 10 and a slag storage component 20 installed at the bottom of the tank body 10.

[0033] In the embodiments of the present application, the tank body 10 is used to contain high-temperature slurry, and a discharge port 11 and a conical slag discharging tank bottom 12 are provided at the bottom end of the tank body 10.

[0034] It should be noted that the slurry can be mixed mud of sand and cement. In other embodiments, the slurry can be paper stock for producing paper.

[0035] In the embodiment of the present application, the slag storage component 20 is used to store the slag discharged from the tank body 10. The slag storage component 20 is connected to the bottom of the slag discharge tank 12 in a through manner. A first slag discharge valve 30 is provided between the slag storage component 20 and the bottom of the slag discharge tank 12. A second slag discharge valve 40 for discharging slag is provided at the slag discharge port of the slag storage component 20. The first slag discharge valve 30 and the second slag discharge valve 40 operate in a dual-valve position control mode. The dual-valve position control mode includes: if the first slag discharge valve 30 works, the second slag discharge valve 40 does not work; if the first slag discharge valve 30 does not work, the second slag discharge valve 40 works.

[0036] It should be noted that both the first slag discharge valve 30 and the second slag discharge valve 40 can be pneumatic valves, enabling the automatic slag discharge device of the tank body to alternately control the first slag discharge valve 30 or the second slag discharge valve 40 through pneumatic means to achieve automatic slag discharge of the slag discharged from the tank body 10. The slag storage component 20 can be selected as a straight pipe. In this embodiment, when the tank body 10 needs to discharge sand, the first slag discharge valve 30 is first opened, and the slag discharged at the bottom of the slag discharge tank 12 quickly enters the slag storage component 20 through the first slag discharge valve 30 due to gravity; when the slag in the slag storage component 20 is discharged, the first slag discharge valve 30 is first closed, and then the second slag discharge valve 40 is opened. At this time, the slag in the slag storage component 20 is discharged. After the slag in the slag storage component 20 is discharged, the second slag discharge valve 40 is closed, completing one slag discharge operation of the automatic slag discharge device of the tank body. The slag storage component 20 can also be selected as other objects with a storage function in other shapes. The slag discharged is such as sand and gravel. In other embodiments, the first slag discharge valve 30 and the second slag discharge valve 40 can also be selected as electric valves that can be automatically controlled, etc.

[0037] Since the sand in the slurry has the largest density, basically sand accumulates at the bottom of the slag discharge tank of the tank body 10, and there is only a small amount of slurry. Therefore, the slag discharged is generally sand and gravel. In the embodiment of the present application, the automatic slag discharge device of the tank body installs a relatively independent slag storage component 20 at the bottom of the slag discharge tank 12 of the tank body 10. After the sand in the slurry in the tank body 10 enters the slag storage component 20, it will not be discharged through the discharge port 11, and the pipeline connected to the discharge port 11 will not be blocked.

[0038] An automatic slag discharging device for a tank body provided by the present application includes a tank body and a slag storage component installed at the bottom of the tank body; the tank body is used for containing high-temperature slurry, and a discharge port and a conical slag discharging tank bottom are arranged at the bottom end of the tank body; the slag storage component is used for storing the slag discharged from the tank body, the slag storage component is connected to the slag discharging tank bottom in a through manner, a first slag discharging valve is arranged between the slag storage component and the slag discharging tank bottom, and a second slag discharging valve for discharging slag is arranged at the sand discharging port of the slag storage component, and the first slag discharging valve and the second slag discharging valve work in a double-valve position control mode; the double-valve position control mode includes: if the first slag discharging valve works, the second slag discharging valve does not work; if the first slag discharging valve does not work, the second slag discharging valve works. By installing a relatively independent slag storage component on the slag discharging tank body of the tank body, the slag discharged from the slurry in the tank body will not be discharged through the discharge port after entering the slag storage component through the first slag discharging valve, and the pipeline connected to the discharge port will not be blocked; by the second slag discharging valve working and closing the first slag discharging valve, the automatic slag discharging of the slag stored in the slag storage component will not affect the operation of the tank body, solving the technical problems that the existing slurry heating tank cannot discharge sand during operation, and manual sand discharging is time-consuming, laborious, endangers personal safety and blocks the pipeline.

[0039] In an embodiment of the present application, a temperature sensor for detecting the temperature inside the slag storage component 20 is arranged on the slag storage component 20.

[0040] It should be noted that the temperature sensor is arranged at the upper end of the slag storage component 20. In this embodiment, the automatic slag discharging device for the tank body first closes the second slag discharging valve 40 and opens the first slag discharging valve 30, and the slag discharged from the tank body 10 enters the slag storage component 20. When the temperature detected by the temperature sensor in real time is greater than the first set temperature threshold, it indicates that the slag storage amount in the slag storage component 20 reaches the slag discharging amount, then the first slag discharging valve 30 is closed and the second slag discharging valve 40 is opened to automatically discharge the slag stored in the slag storage component 20; when the temperature detected by the temperature sensor in real time is less than the second set temperature threshold, it indicates that the slag discharged from the slag storage component 20 is almost discharged (such as the storage amount of the slag discharged from the slag storage component 20 reaches the minimum discharge threshold), then the second slag discharging valve 40 is closed and the first slag discharging valve 30 is opened to store the slag discharged from the tank body 10 into the slag storage component 20. Among them, the specific data of these parameters such as the first set temperature threshold, the second set temperature threshold, and the minimum discharge threshold can be set according to requirements. The automatic slag discharging device for the tank body can detect the temperature inside the slag storage component 20 in real time through the temperature sensor, and automatically control the first slag discharging valve 30 and the second slag discharging valve 40 to work alternately according to this temperature data, and automatically discharge the slag in the tank body 10 without affecting the operation and cleaning of the tank body 10.

[0041] In an embodiment of the present application, a first detection element for detecting the storage amount of discharged slag is provided at the upper end of the slag storage component 20, and a second detection element for detecting the storage amount of discharged slag is provided at the lower end of the slag storage component 20.

[0042] It should be noted that both the first detection element and the second detection element can be infrared sensors. In this embodiment, the first detection element is used to detect the storage amount of the discharged slag stored in the slag storage component 20 by the tank body 10. The second detection element is used to detect the storage amount of the slag storage component 20 during the discharge process of the discharged slag in the slag storage component 20. First, the second slag discharge valve 40 is closed, and the first slag discharge valve 30 is opened. The discharged slag in the tank body 10 enters the slag storage component 20. When the first detection element outputs a signal, it indicates that the slag storage amount in the slag storage component 20 reaches the amount that can be discharged, then the first slag discharge valve 30 is closed, and the second slag discharge valve 40 is opened to automatically discharge the discharged slag stored in the slag storage component 20; when the second detection element outputs a signal, it indicates that the discharged slag in the slag storage component 20 is almost discharged (for example, the storage amount of the discharged slag in the slag storage component 20 reaches the minimum discharge threshold), then the second slag discharge valve 40 is closed, and the first slag discharge valve 30 is opened to store the discharged slag in the tank body 10 into the slag storage component 20.

[0043] In an embodiment of the present application, the first slag discharge valve 30 and the second slag discharge valve 40 alternately adopt a dual-valve position control mode of operation at a first time interval.

[0044] It should be noted that the first time can be 10s to 20s. The automatic slag discharge device of the tank body can alternately control the start of the first slag discharge valve 30 and the second slag discharge valve 40 to operate alternately at intervals of the first time, and automatically discharge the discharged slag in the tank body 10 without affecting the operation and cleaning of the tank body 10.

[0045] In an embodiment of the present application, several sand discharge air pipes for blowing the discharged slag are provided on the side wall surface of the bottom 12 of the slag discharge tank.

[0046] It should be noted that the sand discharge air pipes can be connected to a vacuum pump. The gas provided by the vacuum pump blows the discharged slag adhered to the wall surface of the bottom 12 of the slag discharge tank and / or the discharged slag coagulated together, avoiding the blockage of the slag discharge channel at the bottom 12 of the slag discharge tank and facilitating slag discharge.

[0047] In the embodiment of the present application, during the operation of the tank body 10, continuous sand discharge can be achieved through the automatic slag discharge device of the tank body, improving production capacity and operation efficiency. It can also save costs, site, and reduce investment costs by reducing the number of equipment. During the sand discharge process, the automation degree of the tank body 10 is improved, the airtightness is ensured, the risk of scalding personnel will not be caused, and the labor force is reduced.
