Description

TECHNICAL FIELD

[0001] The utility model relates to a sludge treatment technical field, concretely relates to a sludge discharging and dispersing device. BACKGROUND

[0002] The stable dispersion and discharging of the existing sludge dispersing device can only be realized under the condition that the incoming sludge is stable. Under the condition that the solid content of the incoming sludge, the pipeline conveying pressure and the sludge quality remain unchanged, the sludge output can be adjusted to match the stable dispersion capacity of the dispersing device by adjusting the opening degree of the manual door, so that the stable dispersion of the sludge is realized. When the above factors change slightly, the sludge quality conveyed is too dry or too thick, or the conveying pressure fluctuates, which will cause the sludge output through the manually adjusted door to be incompatible with the dispersion capacity of the dispersing device. At this time, if the opening degree of the manually adjusted door is not adjusted in time, uneven dispersion and uneven sludge output from each discharging pipe will occur, which will affect the combustion condition of the incinerator. Therefore, in order to ensure the stable combustion of the incinerator, manual intervention of the manually adjusted door is required frequently. According to statistics, the number of times of adjusting the sludge in the garbage pit reaches more than 100 times per month on average, which is a large labor cost, and the manual adjustment cannot respond in time, which also has a certain impact on the combustion of the incinerator.

[0024] In the embodiment, the main structure of the sludge discharging and dispersing device is composed of the mutually connected sludge steady flow subassembly 100 and sludge dispersing subassembly 200, the feed end of sludge steady flow subassembly 100 is connected with the discharge end of sludge conveying pipeline 300, and the discharge end of sludge dispersing subassembly 200 is towards incinerator hopper; when the sludge to be mixed with garbage enters sludge steady flow subassembly 100 through sludge conveying pipeline 300, the sludge enters sludge dispersing subassembly 200 with constant pressure through the speed control and steady flow effect of sludge steady flow subassembly 100, ensures that sludge dispersing subassembly 200 is in the optimum working state, so that the sludge entering sludge dispersing subassembly 200 can be uniformly dispersed, and the mixing and burning effect of sludge and garbage is improved.

[0025] As Figure 1As shown, the sludge steady flow assembly 100 includes a screw conveying pipe 103 and a screw driving assembly, the output end of the screw driving assembly is connected with the screw conveying pipe 103, the screw feeding port 1031 of the screw conveying pipe 103 is connected with the discharging end of the sludge conveying pipe 300, and the screw discharging port 1032 of the screw conveying pipe 103 is connected with the feeding end of the sludge dispersion assembly 200. Under the driving of the screw driving assembly, the sludge moves in the screw conveying pipe 103 and enters the sludge dispersion assembly 200 at a constant pressure. It is known that the screw conveying pipe 103 includes a screw conveying assembly, and the screw conveying assembly is driven to operate by the screw driving assembly to realize the operation of the sludge in the screw conveying pipe 103. The screw steady flow adjustment has stronger stability compared with the automatic adjustment of the electric door, and the disturbance to the flow medium in the pipe is reduced. The screw conveying assembly can be arranged in a conventional manner in the art, which will not be described here.

[0026] As shown in Figure 1 The first pressure sensor 104 is arranged near the screw feeding port 1031 to form an embedded pressure measuring point one for detecting the sludge pressure entering the screw conveying pipe 103, and the second pressure sensor 105 is arranged near the screw discharging port 1032 to form an embedded pressure measuring point two for detecting the sludge pressure output by the screw conveying pipe 103. The first pressure sensor 104 and the second pressure sensor 105 are connected with the remote controller, and the remote controller controls the operation of the screw driving assembly according to the difference between the sludge pressure of the screw feeding port 1031 and the sludge pressure of the screw discharging port 1032 to realize that the sludge of the screw discharging port 1032 enters the sludge dispersion assembly 200 at a constant pressure.

[0027] As shown in Figure 1 The screw driving assembly includes a first driving motor 101 and a variable speed gearbox 102, the output end of the first driving motor 101 is connected with the input end of the variable speed gearbox 102, and the output end of the variable speed gearbox 102 is connected with the screw conveying pipe 103. In this example, the first driving motor 101, the variable speed gearbox 102 and the screw conveying pipe 103 are arranged in a vertical direction.

[0028] Further, the first driving motor 101 is a variable frequency driving motor, the rotating speed of which is adjustable, and the rotating direction of which is adjustable in the forward and reverse directions. The variable speed gearbox 102 is installed above the screw conveying pipe 103 through a driving bearing and a flange plate, and the variable speed gearbox 102 is sealed and isolated from the screw conveying pipe 103.

[0029] In this embodiment, the conveying capacity of the screw conveying pipe 103 is designed to be 0.5m3 / h-1.5m3 / h, and the stable sludge flow output by the screw conveying pipe 103 can be realized by controlling the output frequency and the rotating direction of the screw driving assembly according to the pressure difference signals of the embedded pressure measuring point one and the embedded pressure measuring point two.

[0030] Based on past operational experience, the optimal sludge dispersion effect is achieved when the incoming sludge pressure is between 0.7 MPa and 0.75 MPa before entering the sludge dispersion component 200. In the remote controller, the target pressure (at the second pressure sensor 105) is set to 0.71 MPa. This target pressure value can be adjusted according to production needs.

[0031] The first pressure sensor 104 displays a value of P1, and the second pressure sensor 105 is set to P2 (0.71 MPa). The inlet and outlet pressure difference ΔP = P2 - P1. The frequency and direction of the first drive motor 101 are set in the remote controller to track the ΔP value. When ΔP is negative, the outlet pressure of the spiral conveying pipe 103 is less than the inlet pressure, so the first drive motor 101 automatically increases its frequency, increasing the spiral conveying speed and eliminating the pressure difference. Conversely, when ΔP is positive, the first drive motor 101 automatically decreases its frequency or reverses its direction, slowing down the conveying speed. This stabilizes the outlet pressure of the spiral conveying pipe 103, ensuring stable sludge supply to the sludge dispersion component 200.

[0032] In this embodiment, by setting up a spiral conveying pipe 300 and installing pressure sensors at the feed and discharge ends of the spiral conveying pipe 300, the remote controller can control the speed of the first drive motor 101 based on the pressure difference between the feed and discharge ends of the spiral conveying pipe 300. This achieves quantitative distribution of incoming sludge, eliminates pressure fluctuations, and thus controls the stability of incoming sludge, ensuring that the sludge discharge is in a long-term stable state. This guarantees the stable operation of the sludge dispersion component 200, reduces the impact of changes in solids content and sludge quality on sludge dispersion, and achieves uniform sludge dispersion into the incinerator hopper. Moreover, it eliminates the need for personnel to enter the waste pit for sludge adjustment, reducing labor costs.

[0033] like Figure 1 As shown, the sludge dispersion assembly 200 includes a rotary drive assembly, a dispersion tube 203, and a dispersion disc 204. The dispersion tube 203 has a three-way structure, with the inlet port on the side of the dispersion tube 203 connected to the spiral outlet 1032, the top port of the dispersion tube 203 connected to the rotary drive assembly, and the outlet port at the bottom of the dispersion tube 203 facing the incinerator hopper. The dispersion disc 204 is located at the bottom of the outlet port of the dispersion tube 203. The output end of the rotary drive assembly is connected to the dispersion disc 204 and rotates the dispersion disc 204, causing the sludge after passing through the dispersion tube 203 to collide and be thrown out on the rotating dispersion disc 204, being evenly dispersed into small pieces of sludge, which then fall into the incinerator hopper.

[0034] In this embodiment, the rotary drive assembly includes a second drive motor 201 and a drive shaft 202. The output end of the second drive motor 201 is connected to the dispersion disk 204 via the drive shaft 202. The drive shaft 202 is located inside the dispersion tube 203.

[0035] Further, the second driving motor 201 is a variable frequency and speed reduction integrated motor, the rotating speed is adjustable, and the rotating direction is adjustable in the positive and negative directions. The second driving motor 201 and the driving shaft 202 are arranged in a vertical direction, the second driving motor 201 is installed above the dispersion pipe 203 through a driving bearing and a flange plate, and the second driving motor 201 is sealed and isolated from the dispersion pipe 203.

[0036] As shown in Figure 1 The outer circumference of the dispersion disc 204 is further provided with a plurality of blades 205, the blades 205 are used for guiding and distributing the sludge, and the falling sludge can be better thrown out under the action of the high-speed rotating force, so that a sludge distribution effect with better uniformity is formed.

[0037] In the embodiment, the sludge to be mixed with the garbage is sent into the spiral conveying pipe 103 through the spiral feeding port 1031, and is sent to the dispersion pipe 203 from the spiral discharging port 1032 after the spiral conveying. The sludge is impacted and thrown out on the rotating dispersion disc 204, is uniformly dispersed into small pieces of sludge, and is scattered and laid on the garbage pile in the incinerator hopper to be incinerated. In the spiral conveying process, the first pressure sensor 104 and the second pressure sensor 105 arranged at the spiral feeding port 1031 and the spiral discharging port 1032 detect the sludge pressure in the channel in real time, the pressure sensing signal is associated with the running frequency signal of the first driving motor 101, after the set sludge pressure value, the running frequency and the running direction of the first driving motor 101 can be automatically adjusted according to the real-time sludge pressure, so that the purpose of constant pressure sludge conveying is realized. The sludge discharging and dispersing device of the embodiment can accurately respond to the complex changes (pressure, solid content, etc.) of the sludge, timely adjust, and guarantee the combustion effect of the incinerator.

[0038] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, and any technical solution belonging to the idea of the present application belongs to the protection scope of the present application.
