Description

Technical Field

[0001] The utility model relates to the technical field of flow stabilization bins, in particular to a flow stabilization bin structure of a roller press. Background Art

[0002] The flow stabilizing bin is generally installed at the feed port of the roller press. Its function is to ensure that the flow rate of the material entering the roller press is uniform and stable.

[0003] For example, Chinese authorized patent CN217594810 U discloses a flow stabilizing chamber for a roller press for cement grinding rollers, which achieves the purpose of uniform and stable material discharge by providing a pressure reducing cone and flow control blades with a diversion effect.

[0004] However, the above device has at least the following deficiencies, which need further improvement. First, the first motor for driving the pressure reducing cone to rotate is located inside the bin body. Although a protective cover is provided outside the first motor to prevent materials from invading the motor to a certain extent, in order to facilitate the heat dissipation of the motor, a heat dissipation groove is provided on the protective cover. Materials can still enter the motor through the heat dissipation groove, and the heat dissipation effect is not ideal; second, the top of the pressure reducing cone is horizontal, and the pressure reducing cone has a certain centrifugal force when rotating. When some materials fall on the pressure reducing cone, they will be directly thrown out by the centrifugal force instead of flowing through the guide groove; third, the materials are thrown out on the pressure reducing cone in an umbrella-shaped arc path, so the materials will hit the inner wall of the bin body, and some materials will adhere to the inner wall of the bin body and form a crust, but the device is not provided with a corresponding cleaning component.

[0015] (III) Beneficial effects

[0016] The utility model provides a flow stabilizing chamber structure for a roller press, which has the following beneficial effects:

[0017] The roller press steady flow bin structure places the motor outside and hides the related driving components inside the support frame.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, the utility model provides a technical solution: a roller press flow stabilizing bin structure, comprising a bin body 1, a feed pipe 2 is installed on the top of the bin body 1, a support frame 3 is installed on the upper part of the inner cavity of the bin body 1, and one end of the support frame 3 passes through the bin body 1 and extends to the outside thereof.

[0027] like Figure 2-3 As shown, a group of rotatable gears 4 are installed inside the support frame 3, and a conveyor belt 5 is connected between the gears 4. A motor 6 is installed on the support frame 3 outside the warehouse body 1, and the output end of the motor 6 is coaxially fixed with one of the gears 4. The gears 4 and the conveyor belt 5 are hidden inside the support frame 3. At the same time, a plurality of slots are opened on the support frame 3 to ensure the smooth passage of materials to the greatest extent.

[0029] First embodiment

[0030] like Figure 4 As shown, the pressure reducing cone 7 includes a base 71, and an arc-shaped diverter boss 73 is arranged on the top of the base 71. The arc-shaped boss 73 allows all the materials to flow into the discharge channel 74. A splash guard 72 is also installed on the top of the base 1. The splash guard 72 is located on the outside of the diverter boss 73, and a discharge channel 74 is opened between the splash guard 72 and the diverter boss 73. The discharge channel 74 runs through the outer wall of the base 71.

[0031] Second embodiment

[0032] like Figure 5-6As shown, the pressure reducing cone 7 includes a base 71, the top of which is provided with an arc-shaped diverter boss 73, the top of which is also provided with a splash guard 72, the bottom of which is provided with a plurality of discharge channels 74, and the surface of the base 71 is provided with a plurality of baffles 75, which separate the discharge channels 74, so that the material falls onto the diverter boss 73 and is discharged to the surface of the base 71 through the discharge channels 74.

[0033] like Figure 1 As shown, a rotatable flow control blade 9 is installed at the bottom discharge port of the silo body 1, and regulating valve plates 10 are provided on both sides of the flow control blade 9. There is a gap between the regulating valve plate 10 and the flow control blade 9, and the gap is the discharge channel. By controlling the insertion depth of the regulating valve plate 10, the size of the channel can be controlled.

[0034] like Figure 1 As shown, a vibration motor 11 is installed at the bottom of the silo body 1. When the vibration motor 11 is turned on, the silo body 1 can generate a certain vibration, thereby preventing the material from adhering to the inner wall of the silo body 1.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field.

[0036] During use, the material enters the silo body 1 through the feed pipe 2 and falls on the top of the pressure reducing cone 7. Under the blockage of the splash guard 72, the material is evenly discharged along the discharge channel 74. In order to prevent the material from sticking to the inner wall of the silo body 1, the cleaning brush 8 rotates with the pressure reducing cone 7 to clean the inner wall of the silo body 1.

[0037] The flow control blade 9 is driven to rotate by an external power, and the width of the discharge channel is adjusted by adjusting the valve plate 10, so as to control the discharge speed.

[0038] To sum up, the flow stabilizing bin structure of the roller press, by placing the motor externally and hiding the relevant driving components inside the support frame, not only ensures the normal operation of the pressure reducing cone, but also frees the motor from the inside of the bin, greatly improving the operating environment of the motor; secondly, by arranging a splash guard structure on the top of the pressure reducing cone, the material falls directly into the splash guard from the feed pipe, and the splash guard can prevent the material from being thrown out, thereby ensuring that the material flows out through the discharge channel, thereby improving the material feeding stability; thirdly, by arranging a cleaning brush, it rotates with the pressure reducing cone to clean the material adhering to the inner wall of the bin to avoid crusting.
