According to an embodiment of the present invention, referring to fig. 1, a sorting apparatus may specifically include a sorting chamber 100, an overflow tank 200 and a water storage chamber 300, which are disposed in a top area of the sorting chamber 100. Wherein, select separately the chamber 100 top and seted up at least one feed inlet 101 to the material that supplies to select separately gets into selects separately chamber 100. And the bottom of the separation cavity 100 is provided with a plurality of water flow devices for spraying the water in the water storage cavity 300 to the top of the separation cavity 100 to form a fluidized bed. At this time, the overflow bath 200 serves to collect and discharge the light particles. A plurality of discharge devices, including a first discharge pipe 102 and an adjusting device, are also disposed inside the sorting chamber 100. A first discharge pipe 102 is provided at the bottom of the sorting chamber 100 to discharge the heavy particles. The adjusting device is used to change the opening and closing degree of the first discharging pipe 102 towards one end of the overflow tank 200 to adjust the discharging speed of the heavy particles.

The embodiment adopts a fluidized bed separation method to separate materials to be separated, can realize the separation of materials with different particle sizes or densities by changing the flow velocity of jet water flow, and has high separation efficiency. Compared with a classifying screen with similar functions, the fluidized bed separation method adopted by the embodiment has the advantages of small occupied area of equipment, low energy consumption, small maintenance amount and strong universality. In addition, the classifying screen is easy to generate more noise due to vibration, and the fluidized bed separation method can effectively reduce noise pollution and reduce the risk of occupational diseases of workers due to noise pollution.

Specifically, the material to be sorted enters the sorting cavity 100 through the feeding hole 101, and under the action of the fluidized bed, light particles in the material move along the water flow direction, enter the overflow groove 200, and then are discharged to the outside. Heavy particles in the material settle under the action of gravity and are discharged through the first discharge pipe 102. It is noted that the sorting apparatus in this example is suitable for granules having a diameter of 0.1 to 1 mm.

In this embodiment, the adjusting device capable of changing the opening and closing degree of the first discharge pipe 102 towards one end of the overflow tank 200 is arranged, so that the discharge speed of heavy particles is changed, the situation that the first discharge pipe 102 is blocked is effectively avoided, and the service performance and the service life of the equipment are improved.

If the discharge amount of the heavy particles is too large, the opening degree of the first discharge pipe 102 toward one end of the overflow tank 200 may be increased to prevent the first discharge pipe 102 from being clogged. If the discharge amount of the heavy particles is small, the opening degree of the first discharge pipe 102 toward one end of the overflow chute 200 can be properly reduced, so that the heavy particles are prevented from being mixed with excessive water flow or other light particles during discharge to affect the sorting efficiency. If it is not necessary to discharge the heavy particles, the first discharge pipe 102 may be closed toward one end of the overflow bath 200.

In one embodiment, the adjustment device includes a plug 103, a transmission 104, a driving member 105, and a control member. The transmission member 104 is used to connect the pipe plug 103 and the driving member 105. The driving member 105 is preferably a pneumatic cylinder fixed to the top of the separation chamber 100 for driving the driving member 104, so as to drive the pipe plug 103 to move relative to the first discharging pipe 102, thereby changing the opening and closing degree of the first discharging pipe 102 towards one end of the overflow chute 200, and the control member is used for controlling the operation of the driving member 105.

Specifically, the area of the end of the pipe plug 103 facing the transmission member 104 is larger than the area of the end of the pipe plug 103 far away from the transmission member 104. Meanwhile, the area of the end of the pipe plug 103 facing the transmission member 104 is larger than the cross-sectional area of the orifice of the first discharge pipe 102, so as to plug the first discharge pipe 102.

In this embodiment, the opening and closing degree of the first discharge pipe 102 toward the end of the overflow launder 200 can be changed by changing the position of the pipe plug 103 relative to the first discharge launder, thereby realizing the adjustment of the discharge speed of the heavy particles. When the pipe plug 103 is completely separated from the first discharge pipe 102, the first discharge pipe 102 is completely opened toward one end of the overflow launder 200, and at this time, the discharge speed of the heavy particles is accelerated. When the pipe plug 103 abuts against the first discharge pipe 102, the end of the first discharge pipe 102 facing the overflow trough 200 is completely closed, and at this time, the heavy particles are deposited at the bottom of the sorting chamber 100 and cannot be discharged to the outside. When the end of the pipe plug 103 far from the driving member 104 penetrates the first discharging pipe 102 and is not abutted against the first discharging pipe 102, the end of the first discharging pipe 102 facing the overflow chute 200 is completely closed in a half-open state, and the discharging speed of the heavy particles is reduced.

Preferably, the first discharge pipe 102 has a circular cross-section, and the plug 103 has a conical structure. At this time, when the pipe plug 103 moves relative to the first discharge pipe 102, the opening and closing degree of the first discharge pipe 102 towards one end of the overflow groove 200 changes uniformly, which is more beneficial to adjusting the discharge speed of the heavy particles, and especially when fine adjustment is needed, the situation that the first discharge pipe 102 is plugged can be avoided more effectively, thereby improving the service performance and the service life of the device.

Certainly, in actual production, the cross-sectional shape and the profile of the first discharge pipe 102 and the structure of the pipe plug 103 are not limited thereto, and this embodiment only lists an optimal solution, and is not repeated herein, which is all within the protection scope of the present invention.

In one embodiment, the water flow device comprises a water pump and a water suction pipe. Wherein, the water pumping pipe is communicated with the water storage cavity 300, and the water pump is used for pumping the water in the water storage cavity 300 to the water pumping pipe and spraying the water to the top of the sorting cavity 100.

In this embodiment, the range of light particles sorted can be varied by varying the flow rate of the ascending water stream. If the flow velocity of the ascending water flow is large, the range of the separated light particles is enlarged; if the ascending water flow velocity is small, the range of the light particles sorted out becomes small.

In actual production, the size of the velocity of rising water flow should be considered according to concrete situation, does not do the restriction here, all is in the utility model discloses an within the scope of protection. In particular, the control of the upwelling flow rate can be achieved by varying the cross-sectional area of the suction tube.

In one embodiment, the water storage chamber 300 is provided at the bottom of the sorting chamber 100. At this time, the first discharge pipe 102 penetrates the water storage chamber 300 to discharge the heavy particles to the outside. Specifically, the bottom of the water storage chamber 300 is provided with a water inlet 302 for water to enter.

In this embodiment, the water storage chamber 300 is directly disposed at the bottom of the sorting chamber 100, so that the occupied space of the sorting apparatus can be effectively saved, and external pipeline connections are omitted, thereby saving materials and reducing cost. In addition, after the water storage cavity 300 is directly arranged at the bottom of the sorting cavity 100, the time spent by the water pump to pump the water in the water storage cavity 300 to the water pumping pipe is shortened, the water pumping effect is better, and the sorting efficiency is higher.

Preferably, the sidewall of the water storage cavity 300 is provided with a vent 301, so that redundant water flow can be discharged timely, and the phenomenon that the equipment is damaged due to excessive water in the sorting cavity 100 is avoided. In this embodiment, the evacuation port 301 can also prevent the first discharge pipe 102 from being frozen and blocked.

Further, a plurality of water flow devices are evenly distributed at the bottom of the sorting cavity 100, and a plurality of discharge devices are evenly distributed inside the sorting cavity 100.

Relatively, a plurality of discharging equipment evenly distributed are in selecting separately the inside even emission that more is favorable to the heavy particle of chamber 100, make it discharge more fully, can not have the heavy particle local to pile up and the condition that can not discharge takes place, can also further avoid first exhaust pipe 102 to block up, need not often change, maintain first exhaust pipe 102, and daily maintenance is convenient, has improved sorting facilities's performance and life.

Further, the overflow vessel 200 is provided with a second discharge pipe 201 at a bottom thereof, which is inclined toward a lowermost region of the bottom, for discharging the light particles to the outside.

In this embodiment, the inclined bottom of the overflow trough 200 is more favorable for solid-liquid separation of the light particles and the water flow in the overflow trough 200, and the light particles will be deposited on the lower side of the bottom of the overflow trough 200 under the action of the inclined surface. This is to arrange the second discharge pipe 201 near the lowest region of the bottom of the overflow bath 200, so that most of the discharged light particles are desired, and the sorting efficiency is higher.

In one embodiment, the sorting apparatus may further include a sensor disposed at a bottom region of the sorting chamber 100 to detect the content of the heavy particles and electrically transmit the detected information to the adjusting device to adjust the discharge speed of the heavy particles.

Specifically, when the material gets into and selects separately the chamber 100, heavy particle sinks to selecting separately the chamber 100 bottom, if the heavy particle of bottom is less, for avoiding when discharging through the first discharge tube 102 exhaust most be rivers, influence the separation efficiency, the pipe blockage 103 can support and hold first discharge tube 102, makes heavy particle can not discharge through first discharge tube 102. However, when the sensor detects that the heavy particles at the bottom have been accumulated to a certain extent, the control member receiving the detection information controls the operation of the driving member 105, so that the driving member 104 drives the pipe plug 103 away from the first discharge pipe 102, and the heavy particles can be discharged from the first discharge pipe 102. Through setting up the sensor for whole sorting process, including the emission of heavy particle, all accessible automated control system realizes, need not personnel to watch.
