Description

Technical Field

[0001] This utility model relates to a briquetting machine, belonging to the field of waste metal briquetting and pressing technology. Background Technology

[0002] There are two main types of existing horizontal briquetting machines. One type has a briquetting machine whose extrusion mechanism (compression chamber) can slide along the support rod (tie rod), such as the briquetting machine and biscuit press disclosed in Chinese patents with publication numbers CN213675631U and CN101817239B. The other type has a briquetting machine whose extrusion mechanism (compression chamber) remains fixed relative to the support rod (tie rod) and has a separately movable stop, such as the biscuit press disclosed in Chinese patent number CN209566535U. However, both types of horizontal briquetting machines have two supports and a support rod (tie rod or guide column) connecting the two. The extrusion mechanism (compression chamber) is located between the two supports. The compression cylinder is a single large-diameter cylinder (the extrusion force of the compression cylinder of large briquetting machines is generally over 1000 tons, with the largest reaching 2000 tons). The cylinder rod (or compression punch) of the compression cylinder can extend into the extrusion mechanism (compression chamber) to compress the material. The compression cylinder is fixed at the center of one of the supports, and multiple support rods (tie rods or guide columns) can only be distributed around the periphery of the compression cylinder. Due to the large diameter of the compression cylinder, the distance from the center of the support rod (tie rod or guide column) to the compression center (center of the support) is relatively long, resulting in a large volume of both supports and the compression chamber. The overall space occupied by the briquetting machine is large, and both supports need to have strong support. This results in a large size, heavy weight, and high cost for the briquetting machine. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, this utility model provides a briquetting machine that helps to reduce the overall size of the briquetting machine. The specific technical solution is as follows.

[0004] A briquetting machine includes: a first support, a second support, support rods, a compression chamber, and a compression cylinder. The first support and the second support are connected by a plurality of support rods. The compression chamber is located between the first support and the second support and is disposed on the support rods. The compression cylinder is fixed to the first support and is used to compress the material in the compression chamber.

[0005] Its characteristic is that it further includes an extrusion die, and the compression cylinder is provided in two or more forms;

[0006] The extrusion die includes a push plate and an extrusion rod. All the cylinder rods of the compression cylinders are connected to the push plate. One end of the extrusion rod is connected to the push plate, and the other end of the extrusion rod can extend into the compression chamber.

[0007] By adopting the above technical solution, the single large-diameter compression cylinder of the traditional briquetting machine is replaced with two or more compression cylinders with relatively smaller diameters. This means that the compression cylinders do not all need to be located at the center of the first support, and the support rods do not all need to be located on the periphery of all compression cylinders (i.e., the relative positions of the support rods and compression cylinders can be arranged arbitrarily). This helps to reduce the distance from the center of the support rod to the center of the first (second) support, thereby reducing the overall size of the briquetting machine. This not only improves the stress conditions of the first and second supports, but also reduces material costs.

[0008] Furthermore, three support rods are arranged in parallel, distributed at the three corners of an equilateral triangle; all the compression cylinders are centrally symmetrical about the center of the equilateral triangle. Preferably, at least three compression cylinders are distributed at the three corners of a triangle. That is, the support rods and compression cylinders can be arranged alternately.

[0009] Furthermore, four support rods are arranged in parallel, distributed at the four corners of the rectangle; all the compression cylinders are centrally symmetrical about the center of the rectangle. Preferably, at least four compression cylinders are distributed at the four corners of a rectangle or rhombus. That is, the support rods and compression cylinders can be arranged alternately.

[0010] Furthermore, the compression cylinder is provided with 2 to 7 cylinders.

[0011] Furthermore, the support rod passes through the push plate, and the push plate can slide relative to the support rod. That is, the support rod can be used as a guide rod for the push plate, making the push plate run more smoothly under the action of the compression cylinder.

[0012] Furthermore, a feed hopper is also provided on the compression chamber. The material enters the extrusion chamber inside the compression chamber through the feed hopper, and the extrusion rod compresses the material in the extrusion chamber to form a material block under the action of the compression cylinder.

[0013] In one embodiment, the compression chamber is slidably mounted on the support rod, with the material outlet of the compression chamber facing the second support. The second support acts as a pad during material compression. The material in the compression chamber is compressed towards the second support by the extrusion rod, and after being compressed into a block, the compression chamber moves towards the first support, exposing the material block to the outside of the compression chamber (the material block is clamped between the extrusion rod and the second support). Subsequently, the extrusion rod moves towards the first support under the action of the compression cylinder, thereby releasing the material block.

[0014] In another embodiment, the compression chamber is fixedly mounted on the support rod; the briquetting machine also includes a movable stop, with the material outlet of the compression chamber facing the second support; the stop can switch between a first position blocking the material outlet and a second position exposing the material outlet. When the stop is in the first position, it acts as a pad during material compression, and the material in the compression chamber is compressed towards the stop by the extrusion rod. The extrusion force on the stop is directly transmitted to the second support. After the material is compressed into a block, the stop moves to the second position exposing the material outlet, and the extrusion rod squeezes the material block out of the material outlet.

[0015] Furthermore, both the first and second supports are fixed to the base. The first support, the second support, the support rod, and the base together form an integral load-bearing structure, ensuring overall rigidity during material compression.

[0016] Compared with the prior art, this invention can significantly reduce the size of the briquetting machine, making the whole machine more compact; the structural dimensions of the first support, the second support and the compression chamber can all be greatly reduced, which helps to reduce material costs.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1

[0024] See Figures 1-3A briquetting machine includes: a first support 1, a second support 2, support rods 3, a compression chamber 4, and a compression cylinder 5. The first support 1 and the second support 2 are connected by three support rods 3. The compression chamber 4 is located between the first support 1 and the second support 2 and is slidably mounted on the support rods 3. The compression cylinder 5 is fixed to the first support 1 and is used to compress the material in the compression chamber 4.

[0025] It also includes an extrusion die 6 and four compression cylinders 5;

[0026] The extrusion die 6 includes a push plate 6.1 and an extrusion rod 6.2. All the cylinder rods of the compression cylinders 5 are connected to the push plate 6.1. One end of the extrusion rod 6.2 is connected to the push plate 6.1, and the other end of the extrusion rod 6.2 can extend into the compression chamber 4.

[0027] The first support 1 and the second support 2 are both fixed on the base 7; the first support 1, the second support 2, the support rod 3 and the base 7 together form an integral force-bearing structure to ensure the overall rigidity during the material compression process.

[0028] Three support rods 3 are arranged in parallel and distributed at the three corners of an equilateral triangle; four compression cylinders 5 are arranged symmetrically about the center of the equilateral triangle, with one compression cylinder 5 located at the center of the equilateral triangle and the other three compression cylinders 5 distributed at the three corners of a triangle, that is, the support rods 3 and the compression cylinders 5 are arranged alternately.

[0029] The support rod 3 passes through the push plate 6.1, and the push plate 6.1 can slide relative to the support rod 3. That is, the support rod 3 can be used as a guide rod for the push plate 6.1, so that the push plate 6.1 runs more smoothly under the action of the compression cylinder 5. Of course, those skilled in the art will understand that the support rod 3 may not pass through the push plate 6.1, but may be set to avoid the push plate 6.1.

[0030] The compression chamber 4 is also equipped with a feed hopper 4.1. The material enters the extrusion chamber (not shown) inside the compression chamber 4 through the feed hopper 4.1. The extrusion rod 6.2 compresses the material in the extrusion chamber under the action of the compression cylinder 5 to form material blocks. The compression chamber 4 and the feed hopper 4.1 are existing technologies and will not be described in detail here.

[0031] The compression chamber 4 is slidably mounted on the support rod 3. Under the action of the pushing cylinder 8, the compression chamber 4 can slide along the support rod 3. The compression chamber 4 can be fixed on the first bracket 1 (or the second bracket 2 or the base 7). The material outlet 4.2 of the compression chamber 4 faces the second bracket 2. The second bracket 2 acts as a pad during material compression. The material in the compression chamber is compressed towards the second bracket 2 by the extrusion rod 6.2. After being compressed into a block, the compression chamber 4 moves towards the first bracket 1, exposing the material block to the outside of the compression chamber 4 (the material block is clamped between the extrusion rod 6.2 and the second bracket 2). Subsequently, the extrusion rod 6.2 moves towards the first bracket 1 under the action of the compression cylinder 5, thereby releasing the material block.

[0032] It should be noted that although four compression cylinders 5 are provided in the above embodiment, those skilled in the art will understand that two to seven compression cylinders 5 can be provided. Compared with the single large-diameter compression cylinder 5 of the traditional briquetting machine, the present invention uses multiple compression cylinders 5, so that the compression cylinders 5 do not all need to be located at the center of the first support 1, and the support rods 3 do not all need to be located on the periphery of all compression cylinders 5 (that is, the relative positional relationship between the support rods 3 and the compression cylinders 5 can be arranged arbitrarily). This helps to reduce the distance from the center of the support rod 3 to the center of the first support 1 (second support 2), thereby reducing the volume of the entire briquetting machine. This not only helps to improve the stress conditions of the first support 1 and the second support 2, but also reduces the material cost.

[0033] Example 2

[0034] like Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that: four support rods 3 are arranged in parallel, distributed at the four corners of the rectangle; five compression cylinders 5 are provided, one of which is located at the center of the rectangle, and the other four compression cylinders 5 are arranged symmetrically about the center of the rectangle, distributed at the four corners of a rectangle or rhombus. It should be noted that although there are four support rods 3 in Embodiment 2, those skilled in the art will understand that the number of support rods 3 can be set according to specific needs, as long as the overall structure formed by the first bracket 1, the second bracket 2, the support rods 3, and the base 7 meets the working requirements of the briquetting machine.

[0035] Example 3 (not shown)

[0036] The difference between Example 3 and Example 1 (or Example 2) is that the compression chamber 4 in Example 1 is slidably mounted on the support rod 3, while the compression chamber 4 in Example 3 is fixedly mounted on the support rod 3; the briquetting machine also includes a movable stop (not shown), and the material outlet 4.2 of the compression chamber 4 faces the second support 2; the stop can switch between a first position blocking the material outlet 4.2 and a second position exposing the material outlet 4.2. When the stop is in the first position, it acts as a pad during material compression, and the material in the compression chamber is compressed towards the stop by the extrusion rod 6.2. The extrusion force borne by the stop is directly transmitted to the second support 2. After the material is compressed into a block, the stop moves to the second position exposing the material outlet 4.2, and the extrusion rod 6.2 extrudes and releases the material block from the material outlet 4.2. The working method of the briquetting machine in Example 3 is the same as that of the briquetting machine disclosed in Chinese Patent Publication No. CN209566535U.

[0037] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention is not limited to the specific embodiments described above; these embodiments are merely illustrative and not limiting. Those skilled in the art, under the guidance of the present invention, can make many modifications without departing from the spirit and scope of the claims, and all such modifications fall within the protection scope of the present invention.
