Description

Technical Field

[0001] The utility model relates to the technical field of sand and stone separators, and more specifically to a circulating three-stage sand and stone separator. Background Technique

[0002] Sand and stone separators are mainly used to separate mixtures such as sand and stones in industries such as construction, mining, and sand and stone processing;

[0003] As shown in the existing ones {publication (announcement) number: CN103521445A, a continuous multi-stage air separation and classification method for concrete dry aggregate} and {publication (announcement) number: CN204866515U, a tea air separation device}, they are air separation type separators, which are devices that use the principle of aerodynamics to separate materials and can be used as sand and stone separators;

[0004] After the above-mentioned separator blows the material with air, it uses multiple discharge hoppers to collect, and then uses a bag dust collector (i.e., a negative pressure pulse bag dust collector) to collect dust, and is connected to a blower device through the air flow return pipe of the bag dust collector to supply air to reduce energy consumption. In order to improve the structural compactness of the above-mentioned "tea air separation device", the bag dust collector is arranged close to the discharge hopper, that is, the dust inlet position of the bag dust collector is close to the discharge hopper. At this time, when cleaning the bag of the bag dust collector, the dust will fall and disperse into the discharge hopper, resulting in incomplete collection. Content of the Utility Model

Detailed Embodiments

[0021] Such as Figures 1 - 2As shown in the figure, the present utility model proposes a cyclic three-stage separator for sand and gravel, which includes a housing 1, a dust collection device 2, and a dust port 3 that connects the inner cavities of the housing 1 and the dust collection device 2 (as shown in the figure, the dust collection device 2 is fixedly installed at the right end of the housing 1, and the dust port 3 is arranged between the housing 1 and the dust collection device 2 to serve as an opening connecting the inner cavities of the housing 1 and the dust collection device 2);

[0022] The dust collection device 2 is a negative pressure pulse bag filter;

[0023] An air supply component 7, whose air inlet end is arranged below the feed hopper 6, and the air outlet end is fixedly connected to the air outlet end of the dust collection device 2. The air inlet end of the air supply component 7 is fixedly installed outside the housing 1 and is connected to the inside of the housing 1;

[0024] Specifically: The air supply component 7 includes a blower 71, a return air pipe 72 with one pipe end fixedly connected to the air inlet end of the blower 71, an air outlet pipe 73 with one pipe end fixedly connected to the air outlet end of the blower 71, and an air inlet hood 74 fixedly connected to the other pipe end of the air outlet pipe 73;

[0025] The other pipe end of the return air pipe 72 is fixedly connected to the air outlet end of the dust collection device 2. The air inlet hood 74 is fixedly connected to the housing 1 and is arranged above the outer side of the aggregate hopper 51 far from the dust collection device 2 (as Figure 1 shown, the air inlet hood 74 is fixedly installed at the upper left end of the housing 1. When the blower 71 operates, wind is generated. The wind blows through the air outlet pipe 73 to the air inlet hood 74 and then blows into the housing 1, thereby forming a rightward wind in the housing 1, blowing through the dust port 3 into the dust collection device 2. The wind blows from the air outlet end of the dust collection device 2 to the return air pipe 72 to flow back to the blower 71 for wind reflux, reducing energy consumption);

[0026] A feed hopper 6, which is arranged above a set of separation and collection components 5 far from the dust collection device 2, and the feed hopper 6 is fixedly connected to the top end of the housing 1 (as Figure 1 shown, the feed hopper 6 is arranged above the right end of the air inlet hood 74. When discharging materials in this way, the wind classifies the sand and gravel according to weight and drops from heavy to light from left to right);

[0027] It further includes two sets of separation and collection components 5, which are fixedly installed at the bottom end of the housing 1 in sequence facing the dust collection device 2 (as Figure 1 shown, they are arranged in sequence at the left end of the dust collection device 2 at the bottom end of the housing 1);

[0028] Specifically: The separation and collection component 5 includes an aggregate hopper 51 fixedly installed at the bottom end of the housing 1 and a discharge valve 52 fixedly installed at the bottom end of the aggregate hopper 51. The aggregate hopper 51 is connected to the inside of the housing 1. After the aggregate hopper 51 collects the sand and gravel materials, the discharge valve 52 can be opened for discharging (according to the above, the sand and gravel are divided into three levels and collected in two sets of aggregate hoppers 51 and in the inner cavity of the dust collection device 2 through the dust port 3 respectively, thereby achieving three-stage separation);

[0029] A chassis 8, which is fixedly installed at the bottom end of the outer shell 1 to support and stabilize the entire outer shell 1;

[0030] It further includes an anti - escape component 4 fixedly installed on the outer shell 1 for covering and opening the dust inlet 3, so as to close the dust inlet 3. When cleaning the cloth bag of the dust collection device 2 at this time, it can ensure that dust will fall and disperse in the collection position of the dust collection device 2, improving the comprehensiveness of collection (the cloth bag cleaning method of the negative pressure pulse bag dust collector is the prior art, such as pulse cleaning, etc., which will not be described in detail here);

[0031] Specifically: To implement the above - mentioned anti - escape component 4, it is proposed that, as Figures 1 - 2 shown, the specific structure and composition of the anti - escape component 4 can be: The anti - escape component 4 includes a rotary driver 41 fixedly installed on the outside of the outer shell 1 (the rotary driver 41 can be a servo motor, etc.); (as shown in the figure, the rotary driver 41 can be installed at the rear end of the outer shell 1, and the output end of the rotary driver 41 faces forward);

[0032] A rotating shaft 42 passing through opposite ends of the outer shell 1, the outside of the rotating shaft 42 is rotatably connected to the outer shell 1, and the output end of the rotary driver 41 (the rotating shaft 42 passes through the front and rear ends of the outer shell 1, and the through position can be connected by rotating parts such as bearings, and the output end of the rotary driver 41 is fixed to the rear end of the rotating shaft 42);

[0033] A cover plate 43 fixed to the outside of the rotating shaft 42, and a surrounding frame 44 fixed inside the outer shell 1 to form the dust inlet 3 therein. The outer periphery of the cover plate 43 is movably attached to the surrounding frame 44 to cover and open the dust inlet 3 (the surrounding frame 44 is fixedly arranged in a loop shape between the outer shell 1 and the dust collection device 2, and the loop - shaped inner cavity of the surrounding frame 44 is the dust inlet 3. As Figure 2 shown, after the rotary driver 41 drives the rotating shaft 42 and the cover plate 43 to rotate, the left end of the surrounding frame 44 is attached to the cover plate 43, and the dust inlet 3 can be closed, which is convenient to use);

[0034] As Figure 1 shown, the other end of the cover plate 43 opposite to the rotating shaft 42 is close to the inside of the outer shell 1. When the wind flows to the right, the cover plate 43 forms a downward - inclined shape from left to right, which can guide the wind to the dust inlet 3, making the flow more stable;

[0035] It further includes a controller (which can be a PLC controller), which is connected to an external power supply to supply power and control the opening and closing of electrical components.

[0036] The control method of the present utility model is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply belong to the common knowledge in the art, and the present utility model is mainly used to protect mechanical devices, so the control method and wiring layout of the present utility model will not be further explained.
