Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal chute technology, specifically a material distribution type coal chute. Background Technology
[0002] Coal chutes are a general term for coal transport pipelines in industries such as coal, ports, thermal power, coal transfer and storage stations, coal washing plants, and coal-fired industrial boilers. When transporting coal of different qualities, it is often necessary to separate the coal through a sorting method to avoid mixing different qualities of coal together. Therefore, a sorting coal chute has been proposed to solve the above problems. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] The purpose of this utility model is to solve the problem that when transporting coal of different qualities, it is often necessary to separate the coal through a sorting method to avoid mixing coal of different qualities together, and therefore a sorting coal chute is proposed.
[0005] (II) Technical Solution
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] A material distribution type coal chute includes a main pipe, a material distribution box installed at the bottom of the main pipe, and a secondary pipe and a branch pipe connected to the material distribution box. The inner side of the material distribution box is provided with a material distribution mechanism for blocking the branch pipes.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Preferably, the material distribution mechanism includes a sliding hole, and the material distribution box has a sliding hole. An arc-shaped baffle plate is slidably connected to the inner side of the sliding hole. The inner diameter of the arc-shaped baffle plate is greater than or equal to the inner diameter of the main pipe. A limit baffle plate is fixedly connected to the top of the arc-shaped baffle plate. The limit baffle plate fits against the inner wall of the material distribution box. Lugs are fixedly connected to both the front and rear ends of the arc-shaped baffle plate. A bolt extending to the inner side of the material distribution box is threaded onto each lug. Both bolts are threaded onto the inner side of the material distribution box.
[0010] Preferably, a mounting plate is installed on the outer side of the main tube.
[0011] (III) Beneficial Effects
[0012] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0013] This utility model features a material distribution mechanism with the main pipe placed at an angle. Under normal circumstances, when coal is fed into the main pipe, it will fall into the target position through the distribution box and the branch pipe. When coal of different qualities is fed into the main pipe, the material distribution mechanism will block the branch pipe. The coal fed into the main pipe will then fall into the target position through the distribution box and the distribution mechanism, finally falling into the target position through the secondary pipe. This facilitates the material distribution of coal of different qualities. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] In the embodiments, by Figure 1-4 A material distribution type coal chute is provided, comprising a main pipe 1, a material distribution box 2 installed at the bottom of the main pipe 1, and a secondary pipe 3 and a branch pipe 4 connected to the material distribution box 2. The inner side of the material distribution box 2 is provided with a material distribution mechanism 5 for blocking the branch pipe 4.
[0021] With the above setup, the main pipe 1 is placed at an angle, and the secondary pipe 3 and branch pipe 4 are connected to different pipelines, which can transport coal to different target locations. Under normal circumstances, when coal is put into the main pipe 1, the coal will fall into the target location through the distribution box 2 and branch pipe 4. When coal of different quality is put in, the distribution mechanism 5 blocks the branch pipe 4. The coal is put into the main pipe 1, and will fall into the target location through the distribution box 2 and the distribution mechanism 5, and finally through the secondary pipe 3, which facilitates the sorting and processing of coal of different quality.
[0022] Reference Figure 1-4 The material distribution mechanism 5 includes a sliding hole 51. The material distribution box 2 has a sliding hole 51. An arc-shaped baffle plate 52 is slidably connected to the inner side of the sliding hole 51. The inner diameter of the arc-shaped baffle plate 52 is greater than or equal to the inner diameter of the main pipe 1. A limit baffle plate 53 is fixedly connected to the top of the arc-shaped baffle plate 52. The limit baffle plate 53 fits against the inner wall of the material distribution box 2. Lugs 54 are fixedly connected to both the front and rear ends of the arc-shaped baffle plate 52. A bolt 55 extending to the inner side of the material distribution box 2 is threaded onto each of the two lugs 54. Both bolts 55 are threaded onto the inner side of the material distribution box 2.
[0023] With the above structural setup, the arc-shaped baffle 52 is pushed obliquely upward along the sliding hole 51 until the limiting baffle 53 abuts against the inner top wall of the distribution box 2. At this time, the bolt 55 is screwed into the ear piece 54 and the inner side of the distribution box 2 to complete the limiting of the arc-shaped baffle 52. It should be noted that since the main pipe 1 is in an inclined state, the distribution box 2 is also in an inclined state. Therefore, during the process of pushing the arc-shaped baffle 52, the limiting baffle 53 will also move obliquely upward, which will push the coal material that was previously left on the limiting baffle 53 upward. When the limiting baffle 53 is pushed to the opening of the branch pipe 4, the remaining coal material will fall into the branch pipe 4.
[0024] Reference Figure 1-4 Among them, the outer side of the main pipe 1 is equipped with a mounting plate 6;
[0025] With the above-described structure, the main pipe 1 can be fixed by mounting the mounting plate 6 on the fastener, thereby enhancing the stability of the main pipe 1.
[0026] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
