Description

Technical Field

[0001] This utility model relates to the field of crusher technology, specifically a detachable crusher hammer. Background Technology

[0002] Industrial silicon, also known as metallic silicon, is produced by drying and smelting silica sludge. Specifically, wet silica sludge is dried in a special oven and then transferred to a medium-frequency furnace for smelting and impurity removal. Silica sludge is a low-temperature antioxidant, typically soft, with a fine texture, light weight, high porosity, and strong water absorption. Dried silica exposed to air easily generates dust, while industrial silicon produced by medium-frequency furnace smelting is hard and brittle. Given the different characteristics of silicon materials at different stages of industrial silicon production, many problems remain to be solved in the drying, transfer, smelting, and crushing processes.

[0003] During the material crushing stage, the high hardness and brittleness of the smelted silicon ingots place high demands on the crushing equipment. Referring to Chinese invention patent publication number "CN 203061215U", a "novel toothed roller coal crusher" is disclosed, including a crushing mechanism, a transmission system, and a frame assembly. The crushing mechanism comprises two relatively rotating crushing toothed rollers, with the teeth of the rollers being bullet-shaped. The bullet-shaped tooth tips feature a smooth transition design, reducing stress concentration during direct collision with materials and extending the service life of the tooth tips. However, in actual production, the bullet-shaped crushing toothed rollers experience accelerated wear when engaging materials, and the tooth tips are prone to breakage. Since the tooth tips are fixedly welded to the rollers, they must be replaced entirely after breakage, increasing production costs. Utility Model Content

[0004] The purpose of this invention is to provide a detachable crusher hammer to solve the problems mentioned above.

[0005] A detachable crusher hammer includes a hammer body and a hammer head. The hammer head is mounted on the top of the hammer body. The hammer body is cylindrical, the bottom of the hammer head is cylindrical, the middle part of the hammer head is frustum-shaped, and the tip of the hammer head is conical. A coating is welded to the top of the hammer head.

[0006] Preferably, the coating material is tungsten carbide.

[0007] Preferably, the top of the hammer body is provided with a protruding stud, and the bottom of the hammer head is provided with an internal threaded hole that matches the size of the stud. The stud is tightened after being aligned with the internal threaded hole.

[0008] Preferably, the angle between the tip of the hammer head and the horizontal plane is smaller than the angle between the middle of the hammer head and the horizontal plane.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. In this utility model, the hammer head can be easily assembled and disassembled by the stud protruding at the top of the hammer body and the concave threaded hole at the bottom of the hammer head.

[0011] 2. In this utility model, the angle between the tip of the hammer and the horizontal plane is smaller than the angle between the middle of the hammer and the horizontal plane, forming a blunter sharp angle. During the crushing process, the stress generated when the material collides directly with the hammer is dispersed, thus extending the service life.

[0012] 3. In this utility model, a coating is welded to the top of the hammer head, which improves the hardness and rigidity of the hammer head, thereby improving the efficiency of crushing silicon blocks. 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] Please see Figure 1-5 A detachable crusher hammer head according to an embodiment of the present invention includes a hammer body 1 and a hammer head 2. The hammer head 2 is mounted on the top of the hammer body 1. The hammer body 1 is cylindrical in shape. The bottom of the hammer head 2 is cylindrical in shape. The middle part of the hammer head 2 is frustum-shaped. The tip of the hammer head 2 is conical in shape. A coating 21 is welded to the top of the hammer head 2.

[0021] The material of the coating 21 is tungsten carbide.

[0022] The hammer body 1 has a protruding stud 11 at the top, and the hammer head 2 has an internal threaded hole 22 at the bottom that matches the size of the stud 11. The stud 11 is tightened after being aligned with the internal threaded hole 22.

[0023] Among them, the angle 'a' formed by the tip of hammer head 2 and the horizontal plane is smaller than the angle 'b' formed by the middle of hammer head 2 and the horizontal plane. When the sharp hammer head is struck, the small contact area results in a large force at a single point, which can easily lead to wear and damage to the hammer head. In contrast, the blunter hammer head has a larger contact area and disperses the impact force when struck, thus reducing the risk of wear and damage.

[0024] The working principle of this utility model is as follows: First, align the stud of the hammer body 1 with the concave threaded hole 22 of the hammer head 2 and tighten it. Then, fix the hammer body 1 to the crusher toothed roller base. At this point, it can be put into use. If the hammer head 2 is damaged during use, the damaged hammer head 2 can be unscrewed and replaced with a new hammer head 2.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
