Description

Technical Field

[0001] This utility model relates to the field of cement raw material conveying technology, specifically to a raw material conveying device for cement processing. Background Technology

[0002] Raw meal for cement processing is a material formed by mixing and grinding raw materials such as limestone and clay in a certain proportion to a certain fineness. The material is made into raw meal through processes such as crushing, batching, and grinding. Raw meal preparation is divided into two types: dry method and wet method. In the dry method, the raw meal composition is not easy to be uniform and the workshop dust is large, while the wet method is simple to operate, the raw meal composition is easy to control, and the product quality is good.

[0003] In cement production, raw materials are typically conveyed via chutes. These chutes are suitable for pneumatic conveying of dry, powdery materials. However, if the raw materials contain large particles or materials with high moisture content, it may cause blockage of the chutes, significantly impacting production efficiency. Furthermore, substandard raw material particles may cause additional wear and tear on conveying equipment, mills, and other equipment, increasing maintenance costs and downtime. Therefore, it is necessary to add a screening unit to the conveying device to ensure the quality and uniformity of the raw materials and solve the above problems.

[0004] In view of this, a raw material conveying device for cement processing is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional raw material conveying devices for cement processing may cause blockage of the conveying chute and thus affect production efficiency when the raw material being transported contains large particles or high moisture content. This invention provides a raw material conveying device for cement processing.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a raw material conveying device for cement processing, comprising a screw conveyor and a hopper disposed on one side of the screw conveyor, the screw conveyor comprising a conveying pipe and an outlet and an inlet respectively disposed at the top and bottom of the conveying pipe, the inlet being connected to the hopper, the top of the hopper being detachably connected to an installation frame, two symmetrically arranged installation plates being slidably connected within the installation frame, and the installation plates being elastically connected to the inner wall of the installation frame via a first spring, multiple installation blocks being fixedly connected to each of the two installation plates, the multiple installation blocks being slidably connected to a screening unit, a connecting plate being fixedly connected to the installation block, and the connecting plate being elastically connected to the screening unit via a second spring.

[0007] Furthermore, the screening unit includes a frame and a screen fixedly connected within the frame. Multiple sliders with T-shaped cross-sections are fixedly connected to the screening unit. The positions of the sliders are adapted to the positions of the mounting blocks, and each of the mounting blocks has a groove with a size adapted to the slider.

[0008] Furthermore, each of the two mounting plates is fixedly connected to a sliding rod, which passes through the mounting frame. A vibration motor is fixedly connected to the mounting frame, and the vibration motor is fixedly connected to either of the two sliding rods. The vibration motor is used to drive the mounting frame to vibrate in the horizontal direction when started.

[0009] Furthermore, a limiting block is fixedly connected to one end of the slide rod away from the mounting plate. The limiting block is used to prevent the slide rod from falling off the mounting frame, and the cross-sectional dimension of the limiting block is larger than the cross-sectional dimension of the slide rod.

[0010] Furthermore, a baffle is slidably provided on the mounting frame, the length of which is the same as the length of one side of the frame to which the mounting block is fixedly connected. The baffle is used to prevent cement raw material from falling directly into the feed port from the channel between the frame and the mounting frame.

[0011] Furthermore, four mounting blocks are fixedly connected to the frame. The mounting blocks are arranged in an L-shape, and the mounting blocks are arranged symmetrically on both sides of the frame in pairs. The tops of the two mounting blocks on the same side are fixedly connected to the baffle on that side.

[0013] 1. The raw material conveying device for cement processing provided by this utility model can effectively screen cement raw materials through the setting of the screening unit, so as to prevent unqualified particles and impurities in the raw materials from entering the subsequent processes, making the product quality more stable and improving the overall production efficiency.

[0014] 2. The raw material conveying device for cement processing provided by this utility model buffers the impact of materials on the screening unit by setting the first spring and the second spring, thereby improving the service life of the screen and avoiding the problem of frequent screen replacement.

[0015] 3. The raw material conveying device for cement processing provided by this utility model enables the screen to vibrate in multiple directions through the setting of a vibrating motor and a second spring, thereby avoiding the problem of screen blockage during use and thus affecting screening efficiency.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-5 .

[0025] This utility model relates to a raw material conveying device for cement processing, comprising a screw conveyor 1 and a hopper 2 disposed on one side of the screw conveyor 1. The screw conveyor 1 includes a conveying pipe 11 and an outlet 13 and an inlet 12 disposed at the top and bottom of the conveying pipe 11, respectively. The inlet 12 is connected to the hopper 2. A mounting frame 3 is detachably connected to the top of the hopper 2. Two symmetrically arranged mounting plates 5 are slidably connected inside the mounting frame 3, and the mounting plates 5 are elastically connected to the inner wall of the mounting frame 3 by a first spring 6. Multiple mounting blocks 9 are fixedly connected to each of the two mounting plates 5. The multiple mounting blocks 9 are slidably connected to a screening unit 4. A connecting plate 111 is fixedly connected to the mounting blocks 9, and the connecting plate 111 is elastically connected to the screening unit 4 by a second spring 112.

[0026] It should be noted that by setting the second spring 112, when the material falls into the screening unit 4, the elastic action of the second spring 112 can buffer the impact of the material on the screening unit 4. In addition, the vibration of the screening unit 4 with the second spring 112 can also avoid the problem of the screening unit 4 itself clogging.

[0027] In addition, the screening unit 4 includes a frame 41 and a screen 43 fixedly connected in the frame 41. Multiple sliders 42 with T-shaped cross sections are fixedly connected to the screening unit 4. The position of the sliders 42 is adapted to the position of the mounting blocks 9, and multiple mounting blocks 9 are provided with grooves 10 with sizes adapted to the sliders 42.

[0028] like Figure 2 As shown, each of the two mounting plates 5 is fixedly connected with a sliding rod 7, which passes through the mounting frame 3. A vibration motor 113 is fixedly connected to the mounting frame 3. The vibration motor 113 is fixedly connected to either of the two sliding rods 7. The vibration motor 113 is used to drive the mounting frame 3 to vibrate in the horizontal direction when it is started. During the vibration process, the first spring 6 can play the role of buffering and resetting.

[0029] Secondly, a limiting block 8 is fixedly connected to the end of the slide rod 7 away from the mounting plate 5. The limiting block 8 is used to prevent the slide rod 7 from falling off the mounting frame 3. The cross-sectional dimension of the limiting block 8 is larger than that of the slide rod 7. Simply put, when the limiting block 8 is not set, the slide rod 7 may move under the influence of the vibration motor 113 and thus fall off the mounting frame 3, affecting the use of the device.

[0030] Furthermore, a baffle 114 is slidably mounted on the mounting frame 3. The length of the baffle 114 is the same as the length of the side of the frame 41 to which the mounting block 9 is fixedly connected. The baffle 114 is used to prevent cement raw material from falling directly into the feed inlet 12 from the channel between the frame 41 and the mounting frame 3. Figure 3As shown, the length of the baffle 114 is exactly the same as the length of the gap between the frame 41 and the mounting frame 3. The baffle 114 can effectively block the material to prevent the material from entering the feed inlet 12 directly without screening.

[0031] Furthermore, four mounting blocks 9 are fixedly connected to the frame 41. The mounting blocks 9 are arranged in an L-shape. The mounting blocks 9 are arranged symmetrically on both sides of the frame 41 in pairs. The tops of the two mounting blocks 9 on the same side are fixedly connected to the baffle 114 on that side. The mounting blocks 9 are symmetrically arranged on both sides of the frame 41 to keep the frame 41 stable.

[0032] When using this device, first start the screw conveyor 1 and the vibrating motor 113, and then start feeding from above the screening unit 4. Since the screening unit 4 and the mounting frame 3 can slide up and down through the sliding action of the slider 42 and the mounting block 9, and the screening unit 4 moves together with the mounting frame 3 in the horizontal direction, during the feeding process, when the material impacts the screen 43, the screen 43 will vibrate vertically under the action of the second spring 112, while the vibrating motor 113 will drive the screen 43 to vibrate horizontally. This allows the device to perform multi-directional screening while also preventing the screening unit 4 from clogging itself.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
