Description

Technical Field

[0001] The present invention relates to the technical field of viscous material storage equipment, and more particularly to a transfer warehouse for transferring viscous materials. Background Art

[0002] Viscous material silos are widely used in various industries. They can be divided into large, medium and small in terms of capacity; they can be divided into square, conical, spherical, etc. in terms of shape. Their main function is to store and transfer various viscous materials. They need to meet two basic requirements: one is the storage time, and the other is smooth loading / unloading, high filling rate and emptying rate. Usually the first requirement is not difficult to achieve, but the second requirement involves the characteristics of viscous materials and the flow characteristics of viscous materials in the silo. Usually, the silo design should try to avoid funnel flow (large dead zone and low volumetric efficiency). Diffusion flow is suitable for viscous materials with strong abrasiveness. Integral flow silos are usually suitable for most silos (no dead zone and high volumetric efficiency).

[0003] Viscous material silos have different design types because they store different viscous materials with different storage times, different loading and unloading quantities and other requirements. Among them, the material properties of viscous materials, including physical and chemical properties, especially the flow characteristics among physical properties, are very important considerations in silo design.

[0004] The storage bin for viscous materials is different from the conventional storage bin for solid particles (powders) or fluids. It is rarely reported in the literature of various industries. The main viscous materials are characterized by high viscosity, poor fluidity, and even resistance to fluidity. The design of the storage bin for such viscous materials is very technically difficult. The main problems are manifested in the following aspects:

[0005] 1. The filling degree of sticky materials entering the silo is low:

[0006] Due to the high viscosity and large stacking angle of sticky materials, the silo filling degree is low and the silo storage efficiency is low;

[0007] 2. It is difficult to unload the silo:

[0008] Due to the high viscosity of viscous materials, viscous materials are prone to aggregation in the silo, resulting in a large number of dead zones in the silo, poor unloading, or even no unloading.

[0009] In this regard, there is almost no good solution to the storage of sticky materials in the industry. If forced unloading equipment is installed in the sticky material silo, due to the strong viscosity of the sticky material, the sticky material in the silo is squeezed due to the volume limit of the silo, and it is easy to clump / block / bridge. It is difficult to meet the unloading requirements with unloading equipment alone. If the number of unloading equipment is increased blindly, the investment, operating energy consumption and safety risks of the entire silo will also be very high.

[0010] At present, the industry encounters such problems by bypassing the storage of sticky materials, that is, by changing the properties of sticky materials to be close to the properties of ordinary sticky materials, reducing viscosity and increasing fluidity. For example, drying treatment is used to reduce the moisture content of sticky materials, such as thermal drying methods; in addition, the method of adding water to dilute is used to modify the sticky materials to be close to the properties of fluid sticky materials. The thermal drying method will complicate the entire system and greatly increase the investment / operating costs; the method of adding water to dilute to a fluid is inconsistent with the boiler combustion and the design concept of the entire system, and will waste a lot of energy.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] The present invention is described in detail below.

[0058] The viscous material with high viscosity and low fluidity proposed in the present invention can be any one of coal slime, sewage sludge and red mud.

[0059] Embodiment 1:

[0060] like Figure 1 , Figure 3-Figure 8 As shown;

[0061] A transfer bin for transferring viscous materials comprises a bin body 1 with an inlet at the top, a pneumatic filling system 2, a breaking mechanism 3, a material shifting mechanism 4, a discharge device 6, and an air sweeping system 7 installed on the outside of the bin body 1 and connected to the inside of the bin body 1; the pneumatic filling system 2, the breaking mechanism 3, the material shifting mechanism 4 and the discharge device 6 are installed in the bin body 1 and arranged from top to bottom; the pneumatic filling system 2 is located below the inlet; the discharge device 6 is externally connected to a drop pipe.

[0062] During storage, the viscous material enters the bin body 1 through the inlet for storage;

[0063] During the transfer, the viscous material is subjected to the lateral force of the gas or powder flow sprayed into the silo 1 by the pneumatic filling system 2 arranged on the top of the silo 1, and then changes its falling trajectory and falls into the silo 1, so that the stacking angle of the viscous material in the silo 1 changes, thereby improving the filling degree; the viscous material will fall downward, because the viscous material has high viscosity and low fluidity; first, the viscous material is broken up by the breaking mechanism 3, and the broken viscous material falls downward under gravity, and is cut by the material-dispensing mechanism 4 and transported to the unloading device 6; it is transported to the material-dropping pipe through the unloading device 6 for external discharge and transportation; during the transfer process, the pneumatic filling system 2 will inject gas into the silo 1, so as to avoid the bridging and arching of the viscous material during the dropping process, so as to avoid the failure of normal dropping;

[0064] In some possible implementations, in order to prevent the coal slime from bulging when falling;

[0065] The silo body 1 is a columnar structure, including a straight columnar structure 12 with an inlet at the top, and an inverted cone structure 13 coaxially arranged and connected to the straight columnar structure 12; the height of the straight columnar structure 12 along its axial direction is A, and the height of the inverted cone along its axial direction is B, wherein A:B=0.5-1; when the viscous material is a viscous material with weak adhesion, a large value such as 0.8-0.1 can be selected, and for a viscous material with strong adhesion, 0.5-0.7 can be selected.

[0066] The straight columnar structure 12 is cylindrical, and the inverted cone structure 13 is a truncated cone connected to the cylindrical shape; wherein the small end of the inverted cone structure 13 is connected to the straight columnar structure 12; the effect of setting the truncated cone shape with a small top and a large bottom is that the viscous material automatically falls off from the inner wall under the action of gravity and is not prone to hanging on the wall, which effectively reduces bridging and arching.

[0067] Furthermore, the cone angle α of the cone surface of the inverted cone structure 13 is greater than the repose angle of the viscous material.

[0068] In order to effectively transport all the coal slimes to the unloading device 6 through the material-shifting structure, a partition 5 is provided above the unloading device 6, and a chamber for installing the unloading device 6 is formed between the partition 5 and the bottom of the bin body 1; a feeding port connected to the chamber and located directly above the unloading device 6 is provided on the partition 5.

[0069] Preferably, the unloading device 6 is a double-shaft screw unloading device 6 in the prior art;

[0070] In some possible implementations, in order to effectively deliver the coal slime to the discharge device 6 through the material shifting mechanism 4;

[0071] The material-discharging mechanism 4 includes a material-discharging plate 41 coaxially arranged with the inverted cone structure 13 and located above the partition 5, a driving motor located outside the bottom of the bin body 1 and transmission-connected to the material-discharging plate 41, and a material-discharging arm connected to the material-discharging plate 41 and transmission-connected to the output shaft of the driving motor.

[0072] The material-dispensing plate 41 is driven by the driving motor to drive the material-dispensing arm to rotate, cut the sticky material and convey it to the unloading device 6;

[0073] In some possible implementations,

[0074] The material-digging arms are in multiple groups and are arranged along the circumference of the material-digging disc 41; the material-digging arms include an elastic material-digging rod 42 whose one end is connected to the material-digging disc 41, a material-digging blade 43 installed on the material-digging rod 42, and a scraper hook 44 arranged at the other end of the material-digging rod 42; the scraper hook 44 is connected to the material-digging disc 41 through an elastic member 45.

[0075] The material-moving blades 43 are in multiple groups and are arranged along the long direction of the material-moving rod 42;

[0076] The elastic member 45 may be a spring. In the initial state, there is a small gap between the scraper hook 44 and the inner wall of the bin body 1. When the material is being moved, the material moving rod 42 is deformed toward the side close to the elastic member 45 by force. At this time, the elastic member 45 will be in a compressed state and apply a force to the material moving rod 42. In this way, when the material moving rod 42 is subjected to a force applied to it by a highly viscous material, the elastic member 45 applies a reverse force to it, thereby offsetting the force and preventing it from breaking.

[0077] Preferably, the entire material-dispensing arm is made of elastic alloy steel material with wear resistance. The material-dispensing rods 42 are evenly distributed along the circumference of the material-dispensing disk 41, and one end of the material-dispensing rods 42 is horizontally fixed on the side wall of the material-dispensing disk 41 along the tangential direction. Preferably, the material-dispensing blades 43 are oriented in the same direction and are inclined toward the rotation direction of the material-dispensing disk 41.

[0078] Preferably, the material moving rods 42 are in two groups;

[0079] In some possible implementations, in order to effectively break up the coal slime;

[0080] The dispersing mechanism 3 is a double-axis dispersing machine in the prior art;

[0081] In order to break up the agglomerated sticky materials into small particles before entering the unloading stage;

[0082] The breaking up mechanism 3 is installed in the inverted cone structure 13, and includes two sets of rotating shafts 31 rotatably installed in the warehouse body 1 and arranged in parallel, cutting components respectively installed on the two sets of rotating shafts 31 and arranged along the length direction of the rotating shafts, and a rotating shaft driving device which is transmission-connected with the two sets of rotating shafts 31 and is used to control the two sets of rotating shafts 31 to move toward each other; the two sets of rotating shafts 31 move toward each other.

[0083] The shaft drive device adopts a low-speed motor with a reducer directly connected to the double shafts, and the drive device is installed outside the warehouse body 1 for easy inspection and maintenance;

[0084] In some possible implementations,

[0085] Each group of the cutting components includes a plurality of groups of cutting blades 32 arranged circumferentially along the rotating shaft 31 and on the same plane;

[0086] The cutting blade 32 includes a mounting portion 321 with one end mounted on the rotating shaft 31, and a blade portion 322 disposed at one end of the mounting portion 321 away from the rotating shaft 31 and having an arc-shaped cutting edge; a drainage groove 3221 is disposed on the outer side of the blade portion 322; and a hook tooth 323 is disposed on the rear side of the arc-shaped cutting edge in the direction of rotation around the rotating shaft 31.

[0087] In some possible implementations,

[0088] The cutting blades 32 in each group of cutting assemblies are evenly arranged along the circumference of the rotating shaft 31 , and a matching cavity for matching with the cutting blades 32 on the other group of rotating shaft 31 is formed between the two groups of cutting blades 32 .

[0089] The cutting blades 32 on the two parallel rotating shafts 31 rotate synchronously towards each other, wherein when the matching cavity on one set of cutting components rotates to the side close to the other set of rotating shafts 31, the blade rotated to the side close to the rotating shaft 31 will be located in the matching cavity; self-cleaning is achieved through the cooperation between the blade and the matching cavity;

[0090] Furthermore, there are three groups of cutting blades 32 in each group of cutting assemblies, and they are evenly arranged around the circumference of the rotating shaft 31; a shaft sleeve is provided on the rotating shaft 31, and the mounting portion 321 of the cutting blade 32 is vertically mounted on the shaft sleeve.

[0091] Further, such as Fig. 9 As shown, the cutting components on each rotating shaft 31 are multiple groups and are arranged along the axial direction of the rotating shaft 31. The three groups of cutting blades 32 in two adjacent groups of cutting components are staggered, so that a concave-convex groove 33 is formed between the two groups of rotating shafts 31, so that large pieces of viscous materials can fall into the concave-convex groove 33, which is convenient for the cutting range of the arc-shaped blade edge and is conducive to cutting;

[0092] A gap is formed between the cutting components on the same rotating shaft 31; the cutting blade 32 is installed at 90 degrees to the rotating shaft 31, so that the viscous material is broken up from top to bottom, and the cutting effect is achieved through the blade portion 322; the hook teeth 323 are arranged so that during the rotation of the rotating shaft 31, the end of the hook teeth 323 will rotate around the rotating shaft 31 for installing the cutting belt deception to the side close to another set of rotating shafts 31, and exert a downward gripping force on the conveyed viscous material, so that the viscous material is gripped and torn and separated;

[0093] There are multiple groups of drainage grooves 3221 disposed on the side of the blade portion 322, so as to facilitate segmental separation of the cut viscous material after cutting the viscous material.

[0094] By controlling the rotation speed of the two groups of rotating shafts 31 on the same scattering mechanism 3 and the gap between the two adjacent groups of cutting blades 32 arranged along the axial direction on the same rotating shaft 31, the particle size of the discharged particles can be effectively controlled.

[0095] Embodiment 2:

[0096] like Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown,

[0097] A transfer bin for transferring viscous materials comprises a bin body 1 with an inlet at the top, a pneumatic filling system 2, a breaking mechanism 3, a material shifting mechanism 4, a discharge device 6, and an air sweeping system 7 installed on the outside of the bin body 1 and connected to the inside of the bin body 1; the pneumatic filling system 2, the breaking mechanism 3, the material shifting mechanism 4 and the discharge device 6 are installed in the bin body 1 and arranged from top to bottom; the pneumatic filling system 2 is located below the inlet; the discharge device 6 is externally connected to a drop pipe.

[0098] In some possible implementations, in order to prevent the coal slime from bulging when falling;

[0099] The silo body 1 is a columnar structure, including a straight columnar structure 12 with an inlet at the top, and an inverted cone structure 13 coaxially arranged and connected to the straight columnar structure 12; the height of the straight columnar structure 12 along its axial direction is A, and the height of the inverted cone along its axial direction is B, wherein A:B=0.5-1; when the viscous material is a viscous material with weak adhesion, a large value such as 0.8-0.1 can be selected, and for a viscous material with strong adhesion, 0.5-0.7 can be selected.

[0100] The straight columnar structure 12 is in the shape of a square column, and the inverted cone structure 13 is in the shape of a prism connected to the square column; wherein the small end of the inverted cone structure 13 is connected to the straight columnar structure 12 .

[0101] Furthermore, the cone angle α of the cone surface of the inverted cone structure 13 is greater than the repose angle of the viscous material.

[0102] In order to effectively transport all the coal slimes to the unloading device 6 through the material-shifting structure, a partition 5 is provided above the unloading device 6, and a chamber for installing the unloading device 6 is formed between the partition 5 and the bottom of the bin body 1; a feeding port connected to the chamber and located directly above the unloading device 6 is provided on the partition 5.

[0103] In some possible implementations, in order to effectively deliver the coal slime to the discharge device 6 through the material shifting mechanism 4;

[0104] The material-dispensing mechanism 4 includes a material-dispensing frame 47 installed in the inverted cone structure 13 and located above the partition 5, and a linear drive mechanism 46 located outside the bin body 1 and used to control the material-dispensing frame 47 to make a linear motion on the partition 5;

[0105] The material shifting frame 47 includes a plurality of horizontal bars arranged in parallel and perpendicular to the direction of movement thereof, and a connecting rod for connecting two adjacent groups of horizontal bars;

[0107] A drag reduction plate 8 is arranged above the feed port, and an inlet communicating with the feed port is formed between the drag reduction plate 8 and the partition plate 5 .

[0108] The drag reduction plate 8 is inclined and located above the feed port. An inlet is formed between the end of the drag reduction plate 8 close to the partition 5 and the partition 5. The viscous material dispersed by the dispersing mechanism 3 slides from the drag reduction plate 8 to the partition 5, and enters the discharge device 6 through the inlet and the feed port under the drive of the material diverting mechanism 4. The setting of the drag reduction plate 8 will effectively prevent the viscous material from directly entering the feed port, causing the discharge device 6 to be unable to start normally under the gravity of the viscous material.

[0109] In some possible implementations, in order to effectively break up the coal slime;

[0110] The breaking up mechanism 3 is installed in the inverted cone structure 13, and includes two sets of rotating shafts 31 rotatably installed in the warehouse body 1 and arranged in parallel, cutting components respectively installed on the two sets of rotating shafts 31 and arranged along the length direction of the rotating shafts, and a rotating shaft driving device which is transmission-connected with the two sets of rotating shafts 31 and is used to control the two sets of rotating shafts 31 to move toward each other; the two sets of rotating shafts 31 move toward each other.

[0124] In order to avoid the bulging of sticky materials during material dropping;

[0125] A plurality of groups of arc-shaped plates are arranged on the inner wall of the bin body 1 and along its axis. Furthermore, the arc-shaped plates are arranged in the straight columnar structure 12 .

[0126] Furthermore, each group of arc-shaped plates includes a plurality of groups of arc-shaped plates 11 arranged along the circumference of the warehouse body 1; the arc-shaped plates 11 in two adjacent groups of arc-shaped plates are arranged in a staggered manner.

[0127] The arrangement of the arc-shaped plate 11 increases the contact area between the viscous material and the inner wall of the bin body 1, thereby increasing the friction force, changing the flow position of the viscous material, and dispersing its center of gravity, thereby eliminating the arching and bridging of the viscous material due to the center of gravity shift;

[0128] The unloading device 6 is a double screw conveyor, which is controlled by a variable frequency speed regulating motor and can realize stepless adjustment of the unloading force.

[0129] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
