Description

Technical Field

[0001] This utility model belongs to the technical field of slag discharge machine supporting equipment, specifically relating to a slag discharge machine water tank. Background Technology

[0002] The incinerator's ash discharger uses a ram-driven reciprocating structure. Water is supplied to the ash discharger through a water tank, ensuring a certain amount of water within its chamber to extinguish the burned ash. During operation, some ash may flow back into the water tank connected to the rear of the ash discharger due to the ram's reciprocating motion or water flow, affecting the water replenishment effect. Furthermore, due to the varying composition of the waste (mud, sand, lumps), the ash discharge rate is unstable. This leads to inconsistent water consumption during cooling and inconsistent water replenishment after ash discharge, requiring adjustments based on actual conditions. Current solutions involve using a level gauge to detect low and high water levels and then adjusting the gate valve accordingly. However, this method is complex to install, costly to maintain, and has delays in both water replenishment and shutdown. Moreover, water level fluctuations can interfere with the accuracy of the level gauge. Therefore, a new ash discharger water tank is needed to address these technical issues. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a slag discharge machine water tank, including a water tank with an inlet pipe and an outlet pipe. The outlet pipe extends into the slag discharge machine. The outlet end of the outlet pipe has a downward-bent bend, which allows the cavity of the slag discharge machine to communicate with the water tank, preventing large pieces of ash and slag carried by the slag box slide from entering the water tank during reciprocating motion. A float valve is provided at one point on the inlet pipe. The float valve includes a three-way pipe, a piston, and a float that cooperate with each other. The three-way pipe includes an inlet end, an outlet end, and a piston end. The piston end and the inlet end are located on the same straight line. The inlet end is connected to the inlet pipe. The piston enters the three-way pipe from the piston end. The piston is connected to a piston rod. The float is connected to the piston rod through a connecting rod assembly.

[0004] Preferably, the connecting rod assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is connected to a float, and the other end of the first connecting rod is connected to one end of the second connecting rod. The second connecting rod is V-shaped, and a rotating shaft is rotatably connected to the middle of the second connecting rod. The rotating shaft is connected to the outer wall of the piston end through a connecting piece. The bottom of the piston end is provided with an elongated through hole, and the other end of the second connecting rod passes through the through hole and extends into the piston end to connect with the piston rod.

[0005] Preferably, the bottom of the piston rod is provided with an elongated groove, and a connecting rod is provided in the groove. The end of the connecting rod two located in the piston end is provided with a circular hole, the diameter of which is larger than the diameter of the connecting rod, and the connecting rod passes through the circular hole.

[0006] Preferably, one end of connecting rod one is connected to connecting rod two via a locking bolt. The angle between connecting rod one and connecting rod two can be changed as needed by tightening the locking nut to determine the calibrated water level. The height difference between the real-time water level and the calibrated water level affects the displacement of the piston rod, thereby controlling the inlet water flow rate.

[0007] Preferably, the piston rod is further provided with a sealing plug, which is always located inside the piston end of the three-way pipe. This improves the sealing performance and prevents water from leaking out of the piston end, thus affecting the normal operation of the float.

[0008] Preferably, the bottom of the water tank is provided with a conical slag collection box, the slag collection box is provided with a slag outlet, and the slag outlet is provided with a switch valve.

[0009] Preferably, the water tank is equipped with a second water inlet pipe, which has a manual valve. This second water inlet pipe is a manually controlled water circuit to prevent problems with the float valve from causing untimely water replenishment and affecting the normal operation of the slag discharge machine. When the float valve malfunctions, the first water inlet pipe can be closed for maintenance, and the second water inlet pipe can be used temporarily without affecting production.

[0010] Preferably, a check plate is provided at the end of the outlet pipe near the water tank. The upper end of the check plate is hinged to the inner wall of the outlet pipe, and a protruding baffle is fixed on the inner wall of the outlet pipe corresponding to the lower end of the check plate. The baffle is located on the side of the check plate near the water tank. The baffle can prevent the check plate from opening towards the water tank, thus preventing the ash discharger's cavity from pouring ash into the water tank. The incoming water flow will push the check plate towards the ash discharger's cavity, without affecting normal water intake.

[0011] This utility model also includes other components that enable the normal use of a slag discharge machine water tank, all of which are conventional technical means in the field. Furthermore, devices or components not limited in this utility model, such as manual valves, on / off valves, floats, pistons, sealing plugs, and locking bolts, all employ conventional technical means and equipment in the field.

[0012] Working Principle: The outlet pipe has a downward-bent bend, allowing the slag discharger's cavity to connect with the water tank via a bend. This prevents large pieces of slag carried by the slag box slide from entering the water tank and minimizes impact on water replenishment. A float valve and a three-way valve work in tandem. When the water level in the tank reaches the upper limit, the piston blocks the inlet of the three-way valve, preventing water from entering the tank. When the water level drops, the float descends under the action of the connecting rod assembly, and the piston moves towards the piston end of the three-way valve, connecting the inlet and outlet. Water from the first inlet then enters the tank to replenish it until the water level reaches the upper limit. The float valve ensures that water can be replenished from the tank whenever the water level falls below the upper limit, resulting in minimal water level fluctuations and high stability. This ensures a stable and timely water supply to the slag discharger, which is beneficial for production.

[0013] The beneficial effects of this utility model are: it can effectively reduce the amount of impurities entering the water tank from the slag discharge machine; it is easy to install, has low installation and maintenance costs; it allows for timely water replenishment and shutdown; and water level fluctuations have little impact on water replenishment and shutdown, which is beneficial to production.

[0024] Example

[0025] like Figure 1 , 2 As shown in Figures 3, 5, 6, and 7, this utility model provides a water tank for a slag discharger, including a water tank 1. The water tank 1 is provided with an inlet pipe 7 and an outlet pipe 3. The outlet pipe 3 extends into the slag discharger 6. The outlet end 12 of the outlet pipe 3 is provided with a downwardly bent pipe 4. The cavity of the slag discharger 6 can only be connected to the water tank 1 through the bend path, which prevents large pieces of ash and slag carried by the slag discharger slide from entering the water tank 1 when it is pushed back and forth. A float valve is provided at the inlet pipe 7. The float valve includes a three-way pipe, a piston 14, and a float 8 that cooperate with each other. The three-way pipe includes an inlet end 13, an outlet end 12, and a piston end 11. The piston end 11 and the inlet end 13 are located on the same straight line. The inlet end 13 is connected to the inlet pipe 7. The piston enters the three-way pipe from the piston end. The piston 14 is connected to a piston rod 16. The float 8 is connected to the piston rod 16 through a connecting rod assembly.

[0026] The connecting rod assembly includes a first connecting rod 9 and a second connecting rod 10. One end of the first connecting rod 9 is connected to the float 8, and the other end of the first connecting rod is connected to one end of the second connecting rod. The second connecting rod is V-shaped, and a rotating shaft 24 is rotatably connected to the middle of the second connecting rod. The rotating shaft is connected to the outer wall of the piston end 11 through a connecting piece 25. The bottom of the piston end is provided with an elongated through hole 20, and the other end of the second connecting rod passes through the through hole and extends into the piston end to connect with the piston rod 16.

[0027] The bottom of the piston rod is provided with an elongated groove 23, and a connecting rod 21 is provided in the groove. The end of the connecting rod 20 located in the piston end is provided with a round hole 22. The diameter of the round hole 22 is larger than the diameter of the connecting rod 21, and the connecting rod 21 passes through the round hole 22.

[0028] One end of the first connecting rod 9 is connected to the second connecting rod 10 via a locking bolt 19. The angle between the first and second connecting rods can be changed as needed by tightening the locking nut to determine the calibrated water level. The height difference between the real-time water level and the calibrated water level affects the displacement of the piston rod 16, thereby controlling the water inlet flow rate.

[0029] The piston rod 16 is also equipped with a sealing plug 15, which is always located inside the piston end of the three-way pipe. This improves the sealing performance and prevents water from leaking out of the piston end, thus affecting the normal operation of the float 8.

[0030] The bottom of the water tank 1 is provided with a conical slag collection box 2, the slag collection box 2 is provided with a slag outlet, and the slag outlet is provided with a switch valve.

[0031] A check plate 17 is provided at one end of the outlet pipe 3 near the water tank 1. The upper end of the check plate 17 is hinged to the inner wall of the outlet pipe 3. A protruding baffle 5 is fixed on the inner wall of the outlet pipe 3 corresponding to the lower end of the check plate 17. The baffle 5 is located on the side of the check plate 17 near the water tank 1. The baffle 5 can prevent the check plate 17 from opening towards the water tank 1, thus preventing the ash and slag from being poured into the water tank 1 by the cavity of the slag discharger 6. The water flow will push the check plate 17 towards the cavity of the slag discharger 6, without affecting normal water intake.

[0032] Example 2

[0033] like Figure 1-7 As shown, the difference between this embodiment and Embodiment 1 is that the water tank 1 is equipped with a second water inlet pipe 18, which has a manual valve. This second water inlet pipe 18 is a manually controlled water circuit to prevent problems with the float valve from causing untimely water replenishment and affecting the normal operation of the slag discharge machine 6. When the float valve malfunctions, the first water inlet pipe 7 is closed for maintenance, and the second water inlet pipe 18 is used temporarily for water intake, without affecting production. The rest is the same as in Embodiment 1.

[0034] The manual valves and other components mentioned in the above embodiments are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical documents, which are all existing technologies.
