Description

Technical Field

[0001] This utility model relates to the technical field of limestone powder slurry preparation device. Background Technology

[0002] In the process of preparing limestone slurry, limestone powder and water are usually mixed to form slurry. Traditional slurry mixing devices have problems such as uneven mixing and steam leakage, resulting in low slurry preparation efficiency and potential environmental pollution. Therefore, there is a need for a slurry mixing device that can effectively mix limestone powder and water and prevent steam leakage. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a limestone powder slurry mixing device that can solve the above problems.

[0004] To achieve the above objectives, this utility model proposes a limestone powder slurry mixing device, comprising a limestone slurry tank and a lime-water mixer. The lime-water mixer is positioned above the limestone slurry tank. The top of the lime-water mixer has a powder inlet, and the bottom of the lime-water mixer has a slurry outlet. A baffle plate is provided inside the lime-water mixer. The powder inlet and the slurry outlet are respectively located on both sides of the baffle plate. The baffle plate divides the interior of the lime-water mixer into a first chamber and a second chamber. A flow gap is provided between the baffle plate and the rear side wall. The first chamber and the second chamber are connected through the flow gap. A first water inlet is provided on the rear side of the first chamber, and a second water inlet is provided on the front side of the second chamber. The first water inlet and the second water inlet are centrally symmetrical.

[0005] Preferably, the first inlet is provided with a first electric shut-off valve, and the second inlet is provided with a second electric shut-off valve.

[0006] Preferably, the discharge port is connected to the inlet of the limestone slurry tank.

[0007] Preferably, the first water inlet and the second water inlet are located at the same height.

[0008] Preferably, the bottom plate of the ash-water mixer is inclined, and the slurry outlet is located at the lower end of the bottom plate.

[0009] Preferably, the inclination angle of the base plate is 5 degrees.

[0010] Preferably, the tops of the first chamber and the second chamber are respectively hinged with maintenance flaps.

[0011] The beneficial effects of this utility model are as follows: Through the reasonable arrangement of the first and second water inlets, the water enters the limestone slurry tank and forms a rotating water flow. Through the baffles and the rotating water flow in the lime-water mixer, the limestone powder and water are mixed evenly, improving the slurry making efficiency. The liquid seal formed in the lime-water mixer effectively isolates steam, prevents steam leakage, and protects the environment. This utility model has a simple structure, is easy to operate, and is suitable for large-scale industrial production.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0016] See Figure 1 , Figure 2 A limestone powder slurry mixing device includes a limestone slurry tank 1 and a lime-water mixer 2. The lime-water mixer 2 is located above the limestone slurry tank 1. The top of the lime-water mixer 2 has a powder inlet 3, and the bottom of the lime-water mixer 2 has a slurry outlet 4. The lime-water mixer 2 is equipped with a baffle plate 5. The powder inlet 3 and the slurry outlet 4 are respectively located on both sides of the baffle plate 5. The baffle plate 5 divides the interior of the lime-water mixer 2 into a first chamber 21 and a second chamber 22. A flow gap 23 is provided between the baffle plate 5 and the rear side wall. The first chamber 21 and the second chamber 22 are connected through the flow gap 23. The rear side of the first chamber 21 has a first water inlet 6, and the front side of the second chamber 22 has a second water inlet 7. The first water inlet 6 and the second water inlet 7 are centrally symmetrical.

[0017] The baffle plate 5 is vertically installed in the middle of the ash-water mixer 2 and is perpendicular to the front side wall. The center of symmetry of the first water inlet 6 and the second water inlet 7 is located on the central axis of the ash-water mixer 2. The powder inlet 3 and the slurry outlet 4 are centrally symmetrical with respect to the central axis of the ash-water mixer 2.

[0018] The first water inlet 6 is equipped with a first electric shut-off valve 61, and the second water inlet 7 is equipped with a second electric shut-off valve 71.

[0019] The discharge port 4 is connected to the inlet of the limestone slurry tank 1.

[0020] The first water inlet 6 and the second water inlet 7 are set at the same height.

[0021] The bottom plate 8 of the ash-water mixer 2 is inclined, and the slurry outlet 4 is located at the lower end of the bottom plate 8.

[0022] The base plate 8 has an inclination angle of 5 degrees.

[0023] The inclined base plate ensures smooth slurry flow while maintaining a certain liquid seal effect.

[0024] The tops of the first chamber 21 and the second chamber 22 are respectively hinged with maintenance flaps 9.

[0025] The inspection flap can be opened via hinges, making it convenient for staff to perform inspections.

[0026] During operation, limestone powder enters the lime-water mixer through the powder inlet, and water enters the lime-water mixer through two water inlets. Under the action of water flow and rotation, the limestone powder and water are mixed evenly and then the slurry enters the limestone slurry tank from the other side.
