Description

Technical Field

[0001] The utility model relates to the technical field of powder conveying, in particular to a refractory material powder conveying device. Background Art

[0002] The raw materials for the production of refractory materials are mostly powders, which are generally transported by belt conveyors. Due to the light weight of refractory powders, they are greatly affected by air humidity. Therefore, agglomeration problems are easily generated during the loading and unloading and transportation processes.

[0003] After searching, it is found that a Chinese patent document discloses a refractory powder conveying device (publication number: CN213170450U). Although the device crushes the lumps in the powder through the motor and the push rod, and the material can be fed evenly through the push rod, it still has the following defects: although the above-mentioned transfer equipment can crush the lumps during transportation, in actual use, the conveying device will vibrate, and the crushing mechanism is prone to loose installation and detachment of installation connection when vibrated for a long time. Moreover, as long as the lumps of powder are not directly immersed in water, they can be broken up by a slight shake, and there is no need to use expensive equipment to crush them. Utility Model Content

[0004] The utility model aims to provide a refractory powder conveying device to solve the problem of using a crusher to break up powder agglomerates, which is too costly and easily causes disconnection due to equipment vibration.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a refractory material powder conveying device, comprising a frame, a conveyor belt is arranged inside the frame, a transport cavity is assembled at the bottom of the frame, the length of the conveyor belt is less than the length of the frame, and one end of the conveyor belt is aligned and installed with one end of the frame, a gap formed between the other end of the conveyor belt and the frame is connected to the transport cavity, a protective cover is arranged on the upper surface of the frame, a rectangular through hole is opened on the protective cover, a screen is installed in the through hole, and a dust cover is covered outside the screen.

[0006] Preferably, bearing seats are installed on both sides of one end of the frame aligned with the conveyor belt, and the conveyor belt is rotatably connected to the frame through the bearing seats, and a connecting seat for an external motor is assembled at one end of the bearing seat.

[0007] Preferably, a baffle plate having the same width as the conveyor belt is welded on the other end of the frame, and the baffle plate is installed in an upward inclined manner. Due to the inclined installation, the height of the baffle plate is higher than the surface of the conveyor belt.

[0008] Preferably, a driver is installed on the transport cavity, and the driver is assembled at one end of the transport cavity on the same side as the baffle, an auger is provided in the transport cavity, and the driving end of the driver is connected to the auger.

[0009] Preferably, a discharge hole is opened at the other end of the transport cavity, and the line connecting the center of the discharge hole and the center point of the auger is parallel to the length extension line of the transport cavity.

[0010] Preferably, a feed hole is opened at the center of the upper surface of the dust shield, and a conveying pipe is connected to the feed hole to feed the powder onto the screen.

[0011] Preferably, the protective cover is as long as the conveyor belt, and the end opposite to the bearing seat is in a sealing structure.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) This device is divided into two stages of transmission. The first stage uses a conveyor belt for transportation. Its function is to send the powder into the second conveying device, intercept the agglomerated powder during the transmission process, and use the vibration of the equipment itself to break the agglomerated powder. The second stage uses an auger for transmission, which can be transported over long distances. The advantage of using an auger for transportation is that since the powder also has the property of flowing, the use of an auger can prevent omissions during transportation. There are multiple feed ports and discharge ports, and the material can be unloaded at various points as needed. The flow of the material can also be controlled by means of a sliding door or valve. It is adjustable and can be accommodated in a smaller space. When working at a higher position, the auger screw conveyor is easy to install and safer.

[0014] (2) A protective cover is provided on the conveyor belt to prevent the powder from spilling from the equipment. At the same time, a screen provided on the protective cover can intercept the lumps in the powder. A dust cover is provided on the screen to prevent the dust generated by the powder being transported from the pipeline to the conveyor from spreading. After the lumps of powder fall on the screen and are intercepted, the lumps are broken up by the vibration of the equipment itself. In addition, the vibration of the equipment can prevent the powder from accumulating on the drying net and causing blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 1-4 The utility model provides a refractory material powder conveying device, including a main frame 1 of the device, a conveyor belt 2 for primary conveying is arranged in the frame 1, and a conveying cavity 3 for receiving the powder that has been filtered and crushed through the primary conveying is assembled at the bottom of the frame 1. If the powder conveyed by the conveyor belt 2 wants to enter the conveying cavity 3, a through opening is required, so the length of the conveyor belt 2 is set to be smaller than the length of the frame 1, and one end of the conveyor belt 2 is aligned and installed with one end of the frame 1, so that the gap formed between the other end of the conveyor belt 2 and the frame 1 is connected with the conveying cavity 3, and the powder can enter the conveying cavity 3, and a protective cover 4 for preventing the powder from being splashed is arranged on the upper surface of the frame 1, and a rectangular through hole is opened on the protective cover 4, and a screen 52 for intercepting agglomerated powder is installed in the through hole, and a dust cover 5 for preventing dust from spreading is covered outside the screen 52.

[0022] exist Figure 1-4 In the figure, bearing seats 22 are installed on both sides of one end of the frame 1 aligned with the conveyor belt 2, and the conveyor belt 2 is rotatably connected to the frame 1 through the bearing seats 22. A connector 221 for an external motor is installed at one end of the bearing seat 22. The connector 221 is used to drive the external motor to drive the conveyor belt 2 installed on the bearing seat 22 to rotate, thereby realizing primary transportation.

[0023] exist Figure 1-3In the embodiment, when the powder enters the transport cavity 3 through the conveyor belt 2, a certain amount of dust will be generated due to the height difference, so a baffle 11 with the same width as the conveyor belt 2 is welded on the other end of the frame 1. In order to further suppress the height of the dust, the baffle 11 is installed in an upward inclined manner. Since the baffle 11 is installed obliquely, its height is higher than the surface of the conveyor belt 2, so that the dust can be effectively suppressed. At the same time, the baffle 11 can prevent the conveyor belt 2 from throwing the powder too far due to inertia, causing the powder to not fall completely into the transport cavity 3; when the powder is transported to the transport cavity 3, it needs to be transported twice, so a driver 31 is installed on the transport cavity 3, and the driver 31 is assembled between the transport cavity 3 and the baffle 11 At one end of the same side, an auger 311 is provided in the transport chamber 3, and the driving end of the driver 31 is connected to the auger 311 so that the powder is transported for a second time by means of spiral motion; a discharge hole 32 is provided at the other end of the transport chamber 3 for discharging. In order to ensure the uniformity of the discharging and prevent incomplete discharging, the auger 311 and the discharge hole 32 need to be aligned. Therefore, during installation, it is necessary to pay attention to the parallelism of the line connecting the center of the discharge hole 32 and the center point of the auger 311 and the length extension line of the transport chamber 3; a feed hole 51 for powder to enter is provided at the center of the upper surface of the dust cover 5, and a conveying pipe is connected to the feed hole 51 to put the powder onto the screen 52, which can further reduce dust.

[0024] exist Figure 1 In the embodiment, the protective cover 4 is equal in length to the conveyor belt 2 and can effectively cover the conveyor belt 2 to prevent the powder from deviating when falling and causing the material to be scattered. The end opposite to the protective cover 4 and the bearing seat 22 is a sealing structure to prevent the powder from leaking from this end and causing waste.

[0025] When the embodiment of the present application is in use, the pipeline is aligned with the feed hole 51 to feed the refractory powder. After the powder is fed, it enters the dust cover 5 and falls on the screen 52. The screen 52 intercepts the agglomerated particles in the powder, and the remaining powder smoothly passes through the screen 52 and enters the conveyor belt 2. At this time, the protective cover 4 is used to effectively intercept the powder to prevent the powder from being spilled over a large area and falling outside the equipment. In this process, the vibration force when the equipment is started is transmitted to the screen 52, so the agglomerated powder on the screen 52 can be vibrated and broken so that it can pass through the screen 52 smoothly. The powder falls on the conveyor belt 2. Afterwards, the motor connected by the connector 221 will drive the conveyor belt 2 to rotate. The conveyor belt 2 can be rotated on the frame 1 under the premise of being fixed through the bearing seat 22 to transport the powder in the first stage. The transported powder enters the transport chamber 3 through the gap. At this time, the driver 31 drives the auger 311 to rotate to transport the powder in the second stage. The powder is finally transported out from the discharge hole 32. During the whole process, the feeding and transporting direction is opposite to the discharging movement direction. Therefore, the equipment has the function of conveying steering. At the same time, this device can be used to transport materials in an environment with a drop and a narrow space.

[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
