[0054] In this embodiment, a horizontal spiral discharge centrifuge is proposed, which includes a housing 1, a door cover 2, a drum 3, a spiral discharger 4, a feeding device 5, a transmission device 6 and a discharging device 7. The drum 3 is arranged inside the housing 1 so that a separation chamber is formed between the housing 1 and the drum 3, and a liquid outlet is arranged on the housing 1; the spiral discharger 4 is sleeved inside the drum 3, and the outer peripheral wall of the spiral discharger 4 and the inner peripheral wall of the drum 3 form a centrifugal channel 9. The spiral discharger 4 includes a hollow core shaft 41 and a core shaft 41 arranged on the core shaft. The spiral push blade 42 on the core shaft 41 is connected to the centrifugal channel 9, and the spiral push blade 42 abuts against the inner peripheral wall of the drum 3; the feeding device 5 is arranged inside the core shaft 41, and is configured to convey the solid-liquid mixture to be separated to the core shaft 41; the core shaft 41 and the drum 3 are both arranged at the rotating end of the transmission device 6, so that the core shaft 41 and the drum 3 can rotate around their axes; the discharging device 7 is arranged at the end of the centrifugal channel 9 away from the transmission device 6, and is configured to receive the solid phase material after centrifugation. In practical applications, the solid-liquid mixture enters the inside of the drum 3 of the centrifuge through the feeding device 5. The spiral unloading device inside the drum 3 will separate the solid phase material in the solid-liquid mixture under the action of centrifugal force, and discharge it from the centrifuge through the discharging device 7, while the liquid phase material in the solid-liquid mixture will be conveyed to the separation chamber under the action of the centrifugal force of the centrifuge, and then discharged from the centrifuge through the liquid outlet on the shell 1.

[0055] However, during the separation process, part of the liquid phase material or some other impurities may remain on the surface of the solid phase material and will not separate from the solid phase material under the action of centrifugal force, thereby affecting the separation quality of the horizontal spiral unloading centrifuge. To this end, in this embodiment, during the centrifugation of the solid-liquid mixture, a cleaning material is used to wash the liquid phase material or some other impurities attached to the solid phase material.

[0056] Specifically, a plurality of annular baffles 43 are arranged inside the core shaft 41 to enclose a plurality of cleaning chambers 44 with openings, and the plurality of cleaning chambers 44 are connected to the centrifugal channel 9 through spray holes 411 arranged on the core shaft 41; the horizontal spiral unloading centrifuge also includes a cleaning device 8, which is arranged inside the core shaft 41, and the cleaning device 8 is configured to transport cleaning materials into the plurality of cleaning chambers 44.

[0057] It can be understood that during the centrifugation of the solid-liquid mixture, the cleaning material is transported into the cleaning chamber 44 through the cleaning device 8, and the cleaning material flushes the solid phase material passing through the centrifugal pipe 81 through the spray hole 411, that is, flushes part of the liquid phase material or some other impurities attached to the solid phase material. Then, under the continuous rotation of the drum 3, the cleaning material can be separated from the solid phase material to ensure the dryness of the solid phase material, thereby improving the separation quality of the horizontal spiral unloading centrifuge. In addition, the cleaning material is transported into the cleaning chamber 44, and the cleaning material in the cleaning chamber 44 can form a liquid ring layer under the action of centrifugal force, and then under the action of the spray hole 411, it is evenly sprayed onto the solid phase material, and by controlling the cleaning device 8 to continuously transport the cleaning material into the cleaning chamber 44, the flow rate of the cleaning material sprayed from the spray hole 411 is equal to the flow rate of the cleaning material transported into the cleaning chamber 44 by the cleaning device 8, thereby keeping the total volume of the liquid ring layer relatively unchanged, so as to achieve the effect of continuously cleaning the solid phase material.

[0058] It should be noted that the type of cleaning material is selected according to actual working conditions, and in this embodiment, clean water is preferred.

[0059] It should also be noted that the spray holes 411 are evenly distributed on the outer peripheral wall of the core shaft 41, and the apertures of the spray holes 411 are selected according to actual working conditions, which will not be elaborated here.

[0060] In this embodiment, a plurality of cleaning devices 8 are provided, and the plurality of cleaning devices 8 are provided in one-to-one correspondence with the cleaning chambers 44. The number of cleaning chambers 44 is preferably two, and correspondingly, the number of cleaning devices 8 is also two. Such a setting facilitates adjustment of the volume of the cleaning material in a single cleaning chamber 44, so as to further ensure the stability of the solid phase material during the cleaning process.

[0061] Specifically, any cleaning device 8 includes a delivery pump, a pipeline 81 and a pipe head 82. The delivery pump is arranged outside the housing 1, and the pipeline 81 is arranged inside the core shaft 41. One end of the pipeline 81 is connected to the delivery pump, and the other end of the pipeline 81 is connected to the pipe head 82. In actual application, the pipeline 81 runs through the door cover 2, and one end of the pipeline 81 is connected to the delivery pump, and the other end is connected to the pipe head 82. In order to facilitate observation of the cleaning state, according to actual working conditions, an observation window 21 is opened on the door cover 2, and the delivery pump is configured to deliver external cleaning materials to the cleaning chamber through the pipeline and the pipe head.

[0062] In this embodiment, there are preferably two pipelines 81, and the axes of the two pipelines 81 and the axis of the feeding pipe of the feeding device are located at the three vertices of the same equilateral triangle.

[0063] In particular, all the pipe heads 82 are oriented in different directions. This arrangement facilitates the removal of the pipes 81 from the mandrel 41 without interference. When the solid material is cleaned with a cleaning material, if the solid material contains too much liquid material, it may cause incomplete separation of the liquid material from the cleaning material during the centrifugation process, thereby affecting the dryness of the solid material. For this reason, in this embodiment, before cleaning the solid material, the solid-liquid mixture is first concentrated, that is, most or even all of the liquid material in the solid-liquid mixture is separated.

[0064] Specifically, the centrifugal channel 9 includes a concentration section 91 and a centrifugal section 92, the concentration section 91 is connected to the core shaft 41, the centrifugal section 92 is connected to the discharge device 7, and the cleaning chamber 44 is connected to the centrifugal section 92 through the spray hole 411; the concentration section 91 is set in a slope, and the rising end of the concentration section 91 is connected to the centrifugal section 92, and the descending end of the concentration section 91 is provided with an overflow port. It can be understood that after the solid-liquid mixture enters the concentration section 91 of the centrifugal pipeline 81, the liquid phase material will be separated from the solid phase material under the centrifugal action, and part of the liquid phase material will be transported to the separation chamber through the drum 3, and the remaining liquid phase material will move from the rising end of the concentration section 91 to the descending end of the concentration section 91 under the action of the slope, and enter the separation chamber from the overflow port, and the solid phase material separated from the liquid phase material moves to the centrifugal section 92 under the action of the spiral pusher blade 42, and then the solid phase material is cleaned under the action of the spray hole 411.

[0065] In this embodiment, the horizontal spiral unloading centrifuge further includes a lining mesh 10 and a plate mesh 11. The lining mesh 10 is clamped between the plate mesh 11 and the inner wall of the drum 3, and the plate mesh 11 and the drum 3 are detachably connected. It can be understood that for different types of mixed materials to be separated, the operator can further improve the separation quality of the horizontal spiral unloading centrifuge by selecting the lining mesh 10 and the plate mesh 11 with the density or particle size of the liquid phase material in the solid-liquid mixed material. In actual application, the lining mesh 10 is fitted with the inner wall of the drum 3, and then the plate mesh 11 is connected to the drum 3, so as to complete the clamping of the lining mesh 10.

[0066] Specifically, the two ends of the drum 3 are provided with step surfaces, and the two ends of the plate net 11 are provided with bends adapted to the step surfaces; the horizontal spiral unloading centrifuge also includes a pressing ring 12, which is detachably connected to the end of the drum 3, and the pressing ring 12 is configured to push the bend closer to the step surface. It can be understood that under the action of the pressing ring 12, the two ends of the plate net 11 can be kept in contact with the drum 3 to avoid axial movement of the plate net 11 during the separation process, thereby further ensuring the separation quality.

[0067] In particular, the pressing ring 12 includes a connecting portion 121 and an abutting portion 122, wherein the connecting portion 121 abuts against the outer peripheral wall of the drum 3; the connecting portion 121 is vertically connected to the abutting portion 122, the abutting portion 122 is detachably connected to the end of the drum 3, and the abutting portion 122 abuts against the bend. It can be understood that the abutting portion 122 abuts against the end of the drum 3, and the connecting portion 121 abuts against the outer peripheral wall of the drum 3. Such an arrangement can further reduce the axial length of the horizontal spiral unloading centrifuge. It should be noted that the abutting portion 122 is connected to the second drum 32 by bolts.

[0068] In this embodiment, the drum 3 includes a first drum 31 and a second drum 32. One end of the first drum 31 is connected to the rotating end of the transmission device 6, and the other end is detachably connected to the second drum 32. Step surfaces are provided at both ends of the second drum 32, and the plate mesh 11 is clamped between the first drum 31 and the pressing ring 12. The first drum 31 and the second drum 32 are detachably connected to facilitate replacement of the lining mesh 10 and the plate mesh 11, so that the operator can select the lining mesh 10 and the plate mesh 11 with the appropriate mesh size according to the density or particle size of the liquid phase material in the solid-liquid mixture.

[0069] In some other feasible embodiments, the first drum 31 is arranged at a slope, that is, the first drum 31 and the core shaft 41 form a concentration section 91 of the centrifugal channel 9, and the second drum 32 and the shield core shaft 41 form a centrifugal section 92.

[0070] Furthermore, in order to prevent the water vapor in the separation chamber from entering the centrifugal channel 9, thereby affecting the dryness of the solid phase material, a sealing ring 33 is provided between the first drum 31 and the second drum 32 in this embodiment. Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not limitations on the implementation methods of the utility model. For ordinary technicians in the relevant field, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the utility model. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the scope of protection of the claims of the utility model.
