Description

Technical Field

[0001] The utility model relates to the technical field of silo spraying, in particular to an automatic water spraying system for a solid particle silo. Background Art

[0002] The solid particle silo of the ultra-high pressure device is equipped with a silo cleaning system. Water is introduced into the top of the solid particle silo to flush the silo. The water inlet pipeline and the silo water washing pipeline are connected by a metal hose with a quick connector. When cleaning the solid particle silo, the operator needs to connect the water inlet pipeline and the silo water washing pipeline through a metal hose. At the same time, the drainage short circuit at the silo outlet needs to be removed and turned to the drainage pipe. The control room personnel start the silo water washing pump through the DCS and inject cleaning water into the silo. After the cleaning is completed, the on-site operator resets the top water inlet pipeline and the bottom drainage short circuit.

[0003] The solid particle silo of the ultra-high device is very high and needs to be cleaned frequently. Every time the silo is cleaned, the on-site personnel need to climb to the top of the silo to connect the metal hose and remove the drainage short circuit at the bottom of the silo. The workload is heavy. At the same time, the position feedback signal of the water inlet pipeline connection and the drainage pipeline removal cannot be seen on the DCS screen, and the personnel in the control room cannot know whether it is correct. If the water inlet pipeline is not connected correctly, water will enter other silos, causing the product particles to be contaminated by water flushing. If the drainage short circuit is removed incorrectly, the cleaning water in the silo cannot be discharged in time, and the cleaning water enters the equipment, causing equipment damage.

[0020] Example: See Figure 1-Figure 2 As shown, the present embodiment provides an automatic water spray system for a solid particle silo, comprising a water washing tank 1, an upper end of the water washing tank 1 being fixedly connected with a water inlet pipe 11, two solid particle silo bodies 2 being arranged on one side of the water washing tank 1, a lower end of the water washing tank 1 being fixedly connected with a return pipe 25, an end of the return pipe 25 away from the water washing tank 1 being fixedly connected with the upper end of the water washing tank 1, a water washing pump 23 being arranged at the lower end of the water washing tank 1, the tops of the two solid particle silo bodies 2 being connected with the return pipe 25 through a water supply line 12, the two water supply lines 12 at the tops of the two solid particle silo bodies 2 being connected through a connecting pipe 13, and a solenoid valve 22 being installed on the water supply line 12.

[0021] A three-way valve 21 is installed on the water delivery pipeline 12, and the connecting pipe 13 is fixed on the three-way valve 21. The water washing pump 23 is provided with two pumps A and B, one for use and one for backup, to ensure that the water washing pump is always running. Pump A is installed on the return pipe 25, and the water inlet of pump B is connected to the pipe connected to the water inlet of pump A through a pipe, and the water outlet of pump B is connected to the pipe connected to the water outlet of pump A through a pipe. The upper end of the water delivery pipeline 12 is welded to the return pipe 25. The lower end of the solid particle silo body 2 is set in a cone shape. The lower end of the solid particle silo body 2 is fixedly connected to a drain pipe 26, and a reversing valve 24 is fixedly connected to the drain pipe.

[0022] Embodiment: It includes a water washing tank 1, the upper end of the water washing tank 1 is fixedly connected with a water inlet pipe 11, and desalted water is poured into the water inlet pipe 11 to replenish the water inside the water washing tank 1 to 80% of the liquid level. Two solid particle silo bodies 2 are arranged on one side of the water washing tank 1, and the lower end of the solid particle silo body 2 is arranged in a conical shape to facilitate the discharge of cleaning water from the solid particle silo body 2.

[0023] The lower end of the water washing tank 1 is fixedly connected with a return pipe 25, and one end of the return pipe 25 away from the water washing tank 1 is fixedly connected with the upper end of the water washing tank 1. Two water washing pumps 23 connected in parallel with the return pipe 25 are arranged at the lower end of the water washing tank 1. Before starting the water washing pump 23, the pump must be filled with air to prevent cavitation from damaging the pump and to prevent the water outlet of the water washing pump 23 from being blocked, which may cause the water outlet of the water washing pump 23 to be easily blocked, resulting in damage to the water washing pump 23. At the same time, the return pipe 25 is added to the water outlet of the water washing pump 23 to ensure that the water washing pump 23 can be started all the time without causing damage to the water washing pump 23.

[0024] Pour desalted water from the water inlet pipe 11, replenish water inside the water washing tank 1 to 80% liquid level, the solenoid valve 22 is in a closed state, the upper end of the solid particle silo body 2 is fixedly connected with a drainage pipeline 12, the upper end of the drainage pipeline 12 is connected to the reflux pipe 25, the reversing valve 24 at the bottom of the solid particle silo body 2 is in a straight-through direction, open the water washing pump 23, and the washing water returns to the solid particle silo body 2 through the reflux pipe 25. When the solid particle silo body 2 needs to be cleaned, the reversing valve 24 at the bottom of the solid particle silo body 2 is opened, the solenoid valve 22 is opened, and the washing water enters the solid particle silo body 2 for cleaning, and then the washing water is discharged through the bottom drain pipe.

[0025] The lower end of the solid particle silo body 2 is fixedly connected with a drain pipe 26, and the outside of the drain pipe 26 is fixedly connected with a reversing valve 24. Through the arrangement of the solenoid valve 22, the three-way valve 21 and the reversing valve 24, the three-way valve 21 is driven by instrument air and can be remotely controlled by DCS; the three-way valve 21 is in a bypass drain position when the silo is not washed with water, and the three-way valve 21 is turned to a straight-through direction when the silo is washed with water. When the solid particle silo body 2 is washed, the control operator can directly operate the valve switch through the DCS, and can also see the valve switch status, so as to prevent the washing water from entering the wrong silo and causing product loss, while reducing the workload of the on-site operator when cleaning the silo.

[0026] The improvement of this embodiment is that: the water inlet pipeline 11 on the top of the solid particle silo body 2 of the original technology is replaced by a solenoid valve 22 and a three-way valve 21 by using a quick-connect metal hose, and the drainage short circuit disassembled and assembled at the bottom of the solid particle silo body 2 of the original technology is replaced by a reversing valve 24, which solves the problem that the operator needs to remove the short circuit every time the silo is washed, and there is no position display after removal, and the central control DCS cannot display whether it is removed. The utility model replaces the drainage short circuit with a reversing valve, eliminating the work of the operator to disassemble and assemble the drainage short circuit, and only needs to operate the reversing valve on the DCS, and can be displayed on the DCS. The position of the reversing valve can be seen. When the solid particle silo body 2 is cleaned, the control operator can directly operate the valve through the DCS, and the valve switch status can also be seen to prevent the cleaning water from entering the wrong silo. By setting a return route at the water washing pump 23, it is avoided that the water outlet of the water washing pump 23 is easily blocked when the flow at the water outlet of the water washing pump 23 is blocked, which may cause the water washing pump 23 to be damaged. At the same time, a reflux pipe 25 is added to the water outlet of the water washing pump 23 to ensure that the water washing pump 23 can be started all the time. When a fire occurs in the solid particle silo body 2, the solenoid valve 22 and the three-way valve 21 can be directly opened to spray the solid particle silo body 2.
