Description

Technical Field

[0001] This utility model relates to the field of air-material separation, specifically an air-material separation device. Background Technology

[0002] Air separation, also known as wind separation or airflow separation, is a method that uses air as the separation medium to separate solid waste particles according to differences in density and particle size under the action of airflow. In a broader sense, air separation also includes dust collection. It is widely used in the treatment and utilization of municipal solid waste, fibrous solid waste, and agricultural waste such as rice and wheat. During air-material separation, a material separation device is usually required.

[0003] Most existing separation devices use a single, fixed screen plate. Fixed screen plates easily cause damp materials to clump together and accumulate on the screen surface, hindering the effective separation of light and heavy components. They lack a dynamic mechanism for material dispersion, cannot adapt to materials with different moisture levels or particle sizes, and are prone to separation dead zones. Light materials (such as dust) tend to remain, while heavy particles slide unstably, affecting the purity of the final product. Therefore, an air-material separation device is needed to help solve this problem. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an air-material separation device to solve the technical problems of existing separation devices, which mostly use a single fixed screen plate. Fixed screen plates easily cause wet materials to form agglomerates and accumulate on the surface of the screen plate, hindering the effective separation of light and heavy components. They lack a dynamic mechanism for material dispersion, cannot adapt to the material requirements of different humidity or particle size, are prone to separation dead zones, and light materials (such as dust) are easy to remain, while heavy particles slide unstably, affecting the purity of the final product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air-material separation device, including a separation box, a separation chamber inside the separation box, support legs fixed at the four corners of the bottom of the separation box, a feed pipe installed at one end of the top of the separation box, a baffle plate inserted and installed near the bottom of the feed pipe, a baffle rod fixed inside the feed pipe, and a discharge port at the bottom of the separation box, with a discharge pipe installed at the discharge port; Inside the separation chamber, a blocking assembly is installed at an angle and hinged directly below the feed pipe. The blocking assembly is fixed to the wall of the separation chamber by a hinged column and a hinged seat. Inside the separation chamber, a shaking assembly that helps the blocking assembly to shake up and down is installed. A dust removal port is opened on the side of the separation box, and a blowing assembly that helps with air separation is installed on the other side of the separation box.

[0006] The present invention is further configured such that the blocking component includes a support frame, a support cavity is provided at the top of the support frame, a support block is fixed at the top of the support cavity, and a hinge post is fixed at one end on the outer side of the support frame, and the hinge post is hingedly mounted on the hinge seat.

[0007] The present invention is further configured such that the support block is in the shape of an inverted U, and a plurality of support blocks are arranged at equal intervals and staggered on the top of the support frame.

[0008] The present invention is further configured such that the shaking component includes a mounting base fixed on the cavity wall of the separation cavity, a rotating motor is rotatably mounted inside the mounting base, a rotating disk is mounted on the front end of the shaft of the rotating motor, and a support rod is hinged to the outer edge of the rotating disk and the bottom of the support frame.

[0009] The present invention is further configured such that a plurality of blocking rods are provided, and the plurality of blocking rods are arranged equidistantly and alternately inside the feed pipe.

[0010] The present invention is further configured such that the blowing assembly includes a blower installed at the top of the separation box, a duct is installed at the air outlet of the blower, a connecting pipe is installed on the duct, and the connecting pipe communicates with the interior of the separation box.

[0011] The present invention is further configured such that the dust removal port is oblong, and the connecting pipe is provided with several on the conduit.

[0012] In summary, the present invention has the following advantages: Through the cooperation between the blocking component and the shaking component, the rotating motor of the shaking component drives the rotating disk to rotate, and the support frame shakes up and down through the support rod, so that the material forms a thin layer of dynamic dispersion on the concave and convex surface formed by the support block, avoiding blockage caused by material moisture and incomplete separation, and further improving the overall practicality of the device. By using staggered baffles arranged inside the feed pipe to initially disperse the material, agglomerated or large pieces of material can be initially dispersed, avoiding situations such as inadequate separation of agglomerated materials.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] An air-material separation device, such as Figure 1-4 As shown, the separation box 1 includes a separation chamber inside the separation box 1. Support legs 2 are fixed at the four corners of the bottom of the separation box 1. A feed pipe 4 is installed at one end of the top of the separation box 1. A baffle plate 5 is inserted and installed near the bottom of the feed pipe 4. A baffle rod 6 is fixed inside the feed pipe 4. Several baffle rods 6 are arranged equidistantly and alternately inside the feed pipe 4. A discharge port is opened at the bottom of the separation box 1. A discharge pipe 3 is installed at the discharge port.

[0017] By using staggered baffles 6 arranged inside the feed pipe 4 to perform primary dispersion of materials, agglomerated or large pieces of materials can be initially dispersed, avoiding situations such as inadequate separation of agglomerated materials.

[0018] Inside the aforementioned separation chamber, a blocking assembly 7 is installed at an angle and hinged directly below the feed pipe 4. The blocking assembly 7 includes a support frame 71, a support cavity 72 is opened at the top of the support frame 71, a support block 73 is fixed at the top of the support cavity 72, a hinge post 8 is fixed at one end on the outer side of the support frame 71, and the hinge post 8 is hingedly installed on the hinge seat. The support block 73 is generally U-shaped, and several support blocks 73 are equidistantly and staggered at the top of the support frame 71. The blocking assembly 7 is fixed to the cavity wall of the separation chamber through the hinge post 8 and the hinge seat. Inside the separation chamber, a shaking assembly 9 is installed to assist the blocking assembly 7 in shaking up and down. The shaking assembly 9 includes a mounting seat 91 fixed on the cavity wall of the separation chamber. A rotating motor is rotatably installed inside the mounting seat 91. A rotating disk 92 is installed at the front end of the shaft of the rotating motor. Support rods 93 are hingedly installed at the outer edge of the rotating disk 92 and the bottom of the support frame 71.

[0019] Through the cooperation between the blocking component 7 and the shaking component 9, the rotating motor of the shaking component 9 drives the rotating disk 92 to rotate, and the support frame 71 is shaken up and down through the support rod 93, so that the material forms a thin layer of dynamic dispersion on the concave and convex surface formed by the support block 73, avoiding blockage caused by material moisture and incomplete separation, and further improving the overall practicality of the device.

[0020] The separation box 1 has a dust removal port 10 on its side. During operation, a slag discharge pipe can be installed at the dust removal port 10 to collect light impurities. The other side of the separation box 1 is equipped with a blower assembly 11 for auxiliary air separation. The blower assembly 11 includes a blower 111 installed at the top of the separation box 1. A duct 112 is installed at the air outlet of the blower 111. A connecting pipe 113 is installed on the duct 112. The connecting pipe 113 is connected to the inside of the separation box 1. The dust removal port 10 is oblong. Several connecting pipes 113 are provided on the duct 112.

[0021] The blowing assembly 11, which is equipped with multiple connecting pipes 113, distributes air evenly along the width of the separation chamber, avoiding separation dead zones caused by uneven local wind speeds. Combined with the shaking of the blocking assembly 7, lightweight materials are continuously blown to the dust removal port 10, ensuring that the materials can be effectively separated.

[0022] The working principle of this utility model: Material enters the separation chamber from the feed pipe 4. The baffles 6, which are equidistantly and alternately arranged inside the feed pipe 4, form the first layer of obstruction for the material, so that the agglomerated or large pieces of material are initially dispersed. At the same time, the plug-in baffle 5 controls the feed flow rate by adjusting the insertion depth to avoid material blockage.

[0023] The material falls onto the inclined hinged blocking component 7. The support frame 71 is hinged to the separation chamber wall through the hinge column 8. The rotating motor of the shaking component 9 drives the rotating disk 92 to rotate, and the support frame 71 is shaken up and down through the support rod 93, so that the material forms a thin layer of dynamic dispersion on the concave and convex surface formed by the support block 73.

[0024] When the blower 111 of the blower assembly 11 is activated, the airflow is diverted through the airflow conduit 112 to multiple connecting pipes 113 and blown evenly into the separation chamber. Light materials such as dust are blown by the airflow to the elongated dust removal port 10 and discharged, while heavy materials slide down the shaking blocking assembly 7 due to gravity to the discharge pipe 3 to achieve separation.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
