Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sludge centrifugal treatment, and particularly relates to a sludge centrifugal dewatering machine sludge storage hopper unpowered steam discharge device. BACKGROUND

[0002] The sludge generated by the sludge centrifugal dewatering machine can be directly stored in the sludge storage hopper arranged below the sludge centrifugal dewatering machine. From the aspect of clean production, the sludge storage hopper should be of a closed structure. In order to facilitate unloading and external transportation, the sludge storage hopper is generally hoisted on the second floor of the sludge treatment room, so that the sludge can be directly unloaded into the sludge transport vehicle on the first floor of the sludge treatment room for external transportation. The sludge centrifugal dewatering machine uses the principle of high-speed rotation centrifugal separation to realize solid-liquid separation and sludge dewatering. The temperature of the generated sludge is higher than the ambient temperature, especially in winter. A large amount of steam is generated by the evaporation of the sludge in the sludge storage hopper. Since the first floor of the sludge treatment room is a semi-open room, the room temperature is relatively low in winter. The sludge storage hopper is hoisted on the second floor of the sludge treatment room, and the storage bin of the sludge storage hopper is actually located on the upper part of the first floor of the sludge treatment room. The temperature difference between the inside and outside of the sludge storage hopper is large. The steam in the sludge storage hopper condenses into water on the four walls of the sludge storage hopper, resulting in water accumulation around the sludge storage hopper. The water accumulation in the sludge storage hopper causes three problems. First, the water accumulation increases the water content of the dewatered sludge. Second, the water accumulation splashes during the unloading of the sludge storage hopper, polluting the environment on the first floor of the sludge treatment room. Even worse, the water splashes on the operators, causing harm to the operators. Third, the water accumulation leaks and splashes on the transportation road during the transportation of the sludge transport vehicle, polluting the road environment.

[0003] In addition, during the process of discharging the filtrate generated by the sludge centrifugal dewatering machine on the second floor of the sludge treatment room to the filtrate pool on the first floor, the filtrate stand pipe will form air resistance due to the siphon effect, causing the discharge of the filtrate from the sludge centrifugal dewatering machine to be blocked, and even water will overflow from the upper edge of the filtrate discharge port. Generally, a siphon breaking pipe needs to be arranged at the top of the filtrate stand pipe to eliminate the air resistance generated during the discharge of the filtrate from the filtrate stand pipe, so that the filtrate from the sludge centrifugal dewatering machine can be smoothly discharged.

[0004] Therefore, the present application is proposed by the present inventor on the basis of years of experience and practice in the relevant industry, so as to overcome the defects of the prior art. SUMMARY

[0005] The present application aims to provide a sludge centrifugal dewatering machine sludge storage hopper unpowered steam discharge device.

[0042] As shown in Figure 1 , Figure 2 The present application provides a sludge centrifugal dewatering machine sludge storage hopper unpowered steam discharge device, comprising,

[0043] The filtrate vertical pipe 5 is communicated with the sludge centrifugal dewatering machine storage hopper 10 (prior art, generally hoisted on the second floor slab 12 of the sludge treatment room) at the top end of the filtrate vertical pipe 5, and is communicated with the filtrate outlet 9 (prior art, located on the second floor of the sludge treatment room, higher than the sludge centrifugal dewatering machine storage hopper) of the sludge centrifugal dewatering machine through the water seal structure 2 at the top end of the filtrate vertical pipe 5, and the filtrate discharged from the sludge centrifugal dewatering machine generates siphon effect in the process of flowing in the filtrate vertical pipe 5 to suck the steam in the sludge centrifugal dewatering machine storage hopper; the filtrate generated by the sludge centrifugal dewatering machine flows into the filtrate vertical pipe 5, and the filtrate flows downward in the filtrate vertical pipe 5 to generate negative pressure at the upper part of the filtrate vertical pipe 5, that is, siphon effect can be generated.

[0044] The steam releaser 6 for separating steam and filtrate is communicated at the bottom end of the filtrate vertical pipe 5, and the steam release pipe 7 and the filtrate discharge pipe 8 are communicated on the steam releaser 6, the steam is discharged to the outside of the workshop (prior art) through the steam release pipe 7, and the filtrate is discharged to the filtrate storage pool (prior art, located below the first floor ground of the sludge treatment room) through the filtrate discharge pipe 8.

[0045] The present application utilizes the height difference between the sludge centrifugal dewatering machine on the second floor of the sludge treatment room and the filtrate storage pool on the first floor to solve the problem of steam condensation and water accumulation in the storage hopper, and further solve the problems of high water content of sludge, environmental pollution caused by the spraying of sludge during unloading of the storage hopper, and environmental pollution caused by sludge transportation.

[0046] Further, the water seal structure 2 is communicated with the filtrate outlet of the sludge centrifugal dewatering machine through the filtrate communication pipe 1.

[0047] Further, the water seal structure 2 is selected in combination with the amount of filtrate generated by the sludge centrifugal dewatering machine.

[0048] In example one, as shown in Figure 1 The water seal structure 2 is an S-shaped water seal structure, and the water storage depth of the S-shaped water seal structure is greater than or equal to 300 mm. The inlet end of the filtrate communication pipe 1 is connected with the filtrate outlet of the sludge centrifugal dewatering machine, the outlet end of the filtrate communication pipe 1 is connected with the S-shaped water seal structure, and the pipe diameter of the filtrate communication pipe 1 should be consistent with the pipe diameter of the filtrate outlet of the sludge centrifugal dewatering machine.

[0049] In example two, the water seal structure 2 is a P-shaped water seal structure.

[0050] Further, as shown in Figure 1As shown, the top end of the filtrate vertical pipe 5 is provided with a Y-shaped tee structure 3, the first end of the Y-shaped tee structure 3 is communicated with the sludge centrifugal dewatering machine storage hopper, the second end of the Y-shaped tee structure 3 is communicated with the filtrate outlet of the sludge centrifugal dewatering machine, and the third end of the Y-shaped tee structure 3 is communicated with the top end of the filtrate vertical pipe 5.

[0051] Further, the first end of the Y-shaped tee structure 3 is communicated with the sludge centrifugal dewatering machine storage hopper through the steam suction pipe 4.

[0052] In the embodiment one, the outlet end of the S-shaped water seal structure is connected with the filtrate vertical pipe 5 through the second end of the Y-shaped tee structure 3. The inlet end of the steam suction pipe 4 is connected with the sludge centrifugal dewatering machine storage hopper, and the outlet end of the steam suction pipe 4 is connected with the first end of the Y-shaped tee structure 3; the pipe diameter of the steam suction pipe 4 is DN150.

[0053] Further, the steam release device 6 is installed at the lower half (bottom end) of the filtrate vertical pipe 5. Preferably, the steam release device 6 is located at 1.5 meters above the ground of the sludge treatment room.

[0054] When there is a high enough drop between the Y-shaped tee structure 3 at the top end of the filtrate vertical pipe 5 and the steam release device 6, the steam release device 6 can be replaced by a Y-shaped tee type steam release device.

[0055] Further, the outlet end of the steam release pipe 7 is higher than the ground of the second floor of the sludge treatment room by more than 2 meters; the pipe diameter of the steam release pipe 7 is smaller than the pipe diameter of the filtrate vertical pipe 5.

[0056] Further, as shown, Figure 2 the side of the steam release device 6 is provided with a steam outlet, the steam outlet is provided with a steam transition pipe 701 which is inclined upward, the steam transition pipe 701 is connected with the steam release pipe 7, the steam release pipe 7 discharges the steam separated by the steam release device 6 to the outside of the sludge treatment room; the bottom end of the steam release device 6 is provided with a liquid discharge port which is communicated with the filtrate discharge pipe 8.

[0057] Preferably, the included angle between the steam transition pipe 701 and the horizontal plane is 45°.

[0058] Further, the pipe diameter size of the water seal structure 2 (S-shaped water seal structure), the Y-shaped tee structure 3, the filtrate vertical pipe 5 and the filtrate discharge pipe 8 is greater than or equal to the pipe diameter size of the filtrate outlet of the sludge centrifugal dewatering machine. The specific pipe diameter should be determined according to the calculation of the filtrate flow rate of the filtrate vertical pipe 5 which is 0.5-0.8 m / h.

[0059] Further, when the number of sludge centrifugal dewatering machines is more than one, the filtrate communication pipe 1 corresponding to each sludge centrifugal dewatering machine should be connected to the inlet of the S-shaped water seal structure through a first communication pipe, and the steam suction pipe 4 corresponding to the sludge storage hopper of each sludge centrifugal dewatering machine should be connected to the Y-shaped three-way structure 3 through a second communication pipe. The pipe diameter of the first and second communication pipes is the same as that of the filtrate vertical pipe 5.

[0060] When the sludge centrifugal dewatering machine is running, the dewatered sludge enters the sludge storage hopper from the sludge outlet of the sludge centrifugal dewatering machine. Since there is a temperature difference between the sludge in the sludge storage hopper and the ambient temperature, steam is generated in the sludge. At the same time, the filtrate generated by the sludge centrifugal dewatering machine enters the filtrate communication pipe 1, and then flows into the water seal structure 2 (S-shaped water seal structure) and then into the filtrate vertical pipe 5. The filtrate flows downward in the filtrate vertical pipe 5. In the process, negative pressure is generated at the upper part of the filtrate vertical pipe 5. The steam in the sludge storage hopper is sucked into the filtrate vertical pipe 5 through the Y-shaped three-way structure 3 via the steam suction pipe 4, and then enters the steam release device 6 along with the filtrate. The steam release device 6 separates the steam and the filtrate. The steam is discharged to the outside of the workshop through the steam release pipe 7, and the filtrate is discharged to the filtrate storage tank through the filtrate discharge pipe 8.

[0061] In order to make the negative pressure generated by the filtrate vertical pipe 5 be used for sucking the steam in the sludge storage hopper as much as possible, the water seal structure 2 (S-shaped water seal structure) is arranged between the top of the filtrate vertical pipe 5 and the filtrate communication pipe 1 to isolate the air, so as to ensure that the air in the filtrate outlet of the sludge centrifugal dewatering machine enters the filtrate communication pipe 1.

[0062] As described above, the sludge centrifugal dewatering machine sludge storage hopper unpowered steam discharge device has the following beneficial effects:

[0063] The present application utilizes the difference in height between the second layer sludge centrifugal dewatering machine and the first layer filtrate storage tank in the sludge treatment room, and uses the siphon effect generated by the filtrate flowing in the filtrate vertical pipe to suck the steam in the sludge storage hopper, and then discharges the steam in the sludge storage hopper to the outside of the workshop, thereby solving the problem of condensate water in the sludge storage hopper, and further solving the problems of increased moisture content of sludge caused by the condensate water in the sludge storage hopper, environmental pollution caused by the splashing of sludge during unloading of the sludge storage hopper, and environmental pollution caused by sludge transportation.

[0064] The above description is only a specific embodiment of the present application and is not intended to limit the scope of the present application. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present application shall fall within the scope of the present application.
