[0027] Figure 1 Schematically shows a sludge drying cyclone dust collector applicable to the embodiments of the present invention.
[0028] Referring to Figures 1 - 3 As shown, the present application provides a sludge drying cyclone dust collector, including:
[0029] A frame 10 for installing various parts;
[0030] A cyclone chamber 20 for providing a dust removal space; the cyclone chamber 20 is arranged on the frame 10;
[0031] A dust collection chamber 30 for collecting the dust discharged from the cyclone chamber 20; the dust collection chamber 30 is connected to the bottom of the cyclone chamber 20;
[0032] A crusher 40 for crushing the dust in the dust collection chamber 30; the crusher 40 is connected to the dust collection chamber 30.
[0033] In the embodiments of the present application, the gas-containing dust enters the cyclone chamber 20, the gas is discharged from the cyclone chamber 20, the dust is collected in the dust collection chamber 30, and is discharged after being crushed by the crusher 40.
[0034] Exemplarily, the frame 10 includes: a bracket 11, and the cyclone chamber 20 is arranged on the bracket 11.
[0035] In the embodiments of the present application, the bracket 11 is built with a steel frame.
[0036] Exemplarily, the frame 10 further includes: a platform 12, the platform 12 is arranged on the top of the bracket 11, and the cyclone chamber 20 extends out of the platform 12.
[0037] In the embodiments of the present application, the platform 12 is built with a steel plate and is arranged on the top of the bracket 11.
[0038] Exemplarily, the frame 10 further includes: a base 13, and the base 13 is connected to the bottom of the bracket 11.
[0039] In the embodiments of the present application, the base 13 is formed by pouring concrete and is used to stabilize the bracket 11.
[0040] Exemplarily, the cyclone chamber 20 includes: a cylindrical chamber 21 and a conical chamber 22, wherein the bottom of the cylindrical chamber 21 is communicated with the top of the conical chamber 22.
[0041] In the embodiments of the present application, the cylindrical chamber 21 and the conical chamber 22 jointly provide a dust removal space for the sludge.
[0042] Exemplarily, an outlet pipe 23 and an inlet pipe 24 are provided at the top of the cylindrical chamber 21.
[0043] In the embodiment of the present application, the inlet pipe 24 is used for dust and gas to enter, and the outlet pipe 23 is used for discharging gas.
[0044] Exemplarily, a slide valve 25 is provided at the bottom of the cylindrical chamber 21.
[0045] In the embodiment of the present application, the slide valve 25 is used to conduct or disconnect the connection between the cyclone chamber 20 and the dust collecting chamber 30.
[0046] When the dust-containing air flow enters the cyclone chamber 20 from the inlet pipe 24, the air flow changes from linear motion to circular motion. Most of the rotating air flow spirals downward along the inner wall of the cyclone chamber 20 and flows toward the dust collecting chamber 30. This is usually called the outer swirl flow. The dust-containing gas generates a centrifugal force during rotation, and the particles with a density greater than that of the gas are thrown toward the inner wall of the cyclone chamber 20. Once the particles contact the inner wall of the cyclone chamber 20, they lose their inertial force and fall along the wall by the momentum of the inlet velocity and the downward gravity, and enter the dust collecting chamber 30. When the rotating and descending outer swirl air flow reaches the conical chamber 22, it converges toward the center of the dust collector due to the conical contraction, and its tangential velocity continuously increases. When the air flow reaches a certain position at the lower end of the conical chamber 22, it rotates upward from the bottom in the cyclone dust collector in the same rotation direction and continues to make a spiral motion.
[0047] Exemplarily, the dust collecting chamber 30 includes: a dust storage bin 31, the dust storage bin 31 having a first end and a second end, the first end being connected to the bottom of the cyclone chamber 20, and the second end being connected to the crusher 40.
[0048] In the embodiment of the present application, the dust storage bin 31 is used to collect the dust discharged from the cyclone chamber 20.
[0049] Exemplarily, the inner diameter of the first end of the dust storage bin 31 is smaller than the inner diameter of the second end of the dust storage bin 31.
[0050] In the embodiment of the present application, the dust storage bin 31 is in an inverted horn shape, which can prevent dust from sticking to the wall.
[0051] Exemplarily, the crusher 40 includes: a rotating shaft 41 and a propeller 42, wherein the propeller 42 is sleeved on the rotating shaft 41.
[0052] In the embodiment of the present application, the rotating shaft 41 is used to drive the propeller 42 to rotate and can crush dust.
[0053] A sludge drying cyclone dust collector provided by the present application can greatly reduce the workload of manual plugging removal, improve the working environment, and make the process production line more stable.
