Description

Technical Field

[0001] The utility model belongs to a conveying device, and particularly relates to a lime conveying device. Background Art

[0002] Lime powder, also known as white lime powder, is a white powdery substance mainly composed of calcium carbonate. After adding water, lime powder can coagulate, harden, and has a cementing effect on other substances. Its application range is very wide. Commonly, it is used in the construction industry, that is, industrial calcium carbonate. Another type is food-grade calcium carbonate, which is widely used as a common calcium supplement. When lime powder needs to be transferred, it needs to be conveyed through a conveying device, and lime powder is prone to react with water and carbon dioxide in the air to form lumps during the conveying process.

[0003] Chinese Patent with the publication number CN211732824U discloses a lime powder spiral conveying device, including a base and a conveying table. An inlet table is fixedly arranged on the base. The top of the inlet table is provided with a feed inlet communicating with the inside of the inlet table. A rotating motor is arranged inside the base. The conveying table is fixed on the top of the base. A rotating rod is arranged inside the rod box. A screw conveyor is arranged on the rotating rod in a rising spiral shape. A cover plate is arranged on the top of the conveying table. A filter screen is arranged on the right side of the fan, and a discharge port is arranged on the outer side of the top of the conveying table.

[0004] However, the above patent has the following deficiencies:

[0005] The above patent drives the rotating rod and the screw conveyor to rotate by setting a rotating motor, so as to drive the lime at the bottom of the conveying table to rise to the top of the conveying table. However, the above patent does not set a device for dispersing the agglomerated lime powder at the position of the inlet table, so the agglomerated lime powder will block the inside of the device when the device conveys the lime powder. Content of the Utility Model

[0006] The utility model provides a lime conveying device, aiming to solve the problem mentioned in the above background art that there is no device for dispersing the agglomerated lime powder, so the agglomerated lime powder will block the inside of the device when the device conveys the lime powder.

[0007] The utility model is realized as follows: A lime conveying device includes a conveying cylinder. A discharge pipe is connected and communicated with the top of the outer wall of the conveying cylinder. A feed pipe is connected and communicated with the bottom of the outer wall of the conveying cylinder. A feed hopper is fixedly connected to the top of the feed pipe. A crushing component for dispersing the agglomerated lime powder is arranged inside the feed pipe;

[0008] The crushing component includes a fixing frame and a mounting plate. The fixing frame is arranged inside the feed pipe, and the outer periphery of the fixing frame is fixedly connected with the inner wall of the feed pipe;

[0009] The side wall of the mounting plate is fixedly connected to the outer wall of the conveying cylinder. A rotating disk is rotatably arranged at the bottom of the mounting plate. A connecting rod is arranged between the rotating disk and the fixing frame. The top of the connecting rod is eccentrically connected to the rotating disk through a universal ball head. The bottom of the connecting rod is connected to the fixing frame through a universal ball head. The connecting rod is obliquely arranged. A crushing block is fixedly connected to the outer periphery of the connecting rod. The top of the crushing block is conical.

[0010] A conveying component for conveying lime powder is arranged inside the feed pipe.

[0011] A transmission component for simultaneously driving the conveying component and the crushing component is arranged at the top of the conveying cylinder.

[0012] When the mounting plate rotates, it can drive the top end of the connecting rod to rotate around the center of the mounting plate. At this time, the connecting rod will rotate in a circle around the mounting plate obliquely. At the same time, the crushing block on the outer periphery of the connecting rod will move in a circle inside the feed pipe. At this time, the distance between the outer periphery of the crushing block and the inner wall of the feed pipe will approach and move away periodically. In this way, the lumpy lime powder passing between the crushing block and the inner wall of the feed pipe can be extruded and crushed. Under the action of gravity, the crushed lime powder will enter the conveying pipe through the gap between the crushing block and the inner wall of the feed pipe.

[0013] Preferably, the conveying component includes a first rotating rod. The first rotating rod is arranged inside the conveying cylinder. The middle part of the first rotating rod penetrates through the top of the conveying cylinder. The first rotating rod is rotatably connected to the conveying cylinder. A spiral conveying blade is fixedly connected to the outer periphery of the first rotating rod. The outer periphery of the spiral conveying blade is in contact with the inner wall of the conveying cylinder.

[0014] When the first rotating rod rotates, it can drive the spiral conveying blade to rotate synchronously. Thus, the lime powder can be pushed by the rotating spiral conveying blade from the bottom of the conveying cylinder to the top of the conveying cylinder, and finally the lime powder is discharged from the discharge pipe.

[0015] Preferably, the transmission component includes a mounting frame and a first transmission wheel. The bottom of the mounting frame is fixedly connected to the top of the conveying cylinder. A stepping motor is fixedly connected to the top of the mounting frame. The output shaft of the stepping motor is fixedly connected to the first rotating rod.

[0016] The first transmission wheel is sleeved on the outer periphery of the first rotating rod. The first transmission wheel is fixedly connected to the first rotating rod. A second rotating rod is arranged on one side of the first transmission wheel. The middle part of the second rotating rod penetrates through the mounting frame. The second rotating rod is rotatably connected to the mounting frame. The bottom of the second rotating rod is fixedly connected to the rotating disk. A second transmission wheel is fixedly connected to the outer periphery of the second rotating rod. A transmission belt is sleeved between the second transmission wheel and the first transmission wheel.

[0017] By starting the stepper motor, the first rotating rod can be directly driven to rotate, thereby realizing the drive of the conveying component. At the same time, the first rotating rod will drive the first transmission wheel to rotate, and the first transmission wheel will drive the second transmission wheel and the second rotating rod to rotate through the transmission belt. At this time, the second rotating rod can drive the rotating disk to rotate, thereby completing the drive of the crushing component. Thus, the drive of the conveying component and the crushing component can be completed simultaneously in the above manner. Since the driving power used only comes from one stepper motor, it is convenient to repair and maintain the device.

[0018] Preferably, a protective tube is sleeved on the outer periphery of the second rotating rod. The top of the protective tube is fixedly connected to the mounting frame, and the bottom of the protective tube is fixedly connected to the mounting plate.

[0019] By providing the protective tube, the outer periphery of the second rotating rod can be protected, thereby avoiding the second rotating rod exposed outside the device from winding foreign objects during rotation, and thus improving the reliability of the device.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: A lime conveying device of the present utility model:

[0021] 1. By providing the crushing component, the agglomerated lime powder entering the feed pipe can be continuously crushed by the crushing blocks moving in a circular motion, thereby avoiding the agglomerated lime powder from entering the conveying component and further avoiding the conveying component from being blocked by the agglomerated lime powder.

[0022] 2. The transmission components provided in the device can drive the conveying component and the transmission component simultaneously. At the same time, since the driving power used only comes from one stepper motor, it is convenient to repair and maintain the device. BRIEF DESCRIPTION OF THE DRAWINGS
