Description

Technical Field

[0001] This utility model relates to the technical field of accelerator processing equipment, and more specifically, to an accelerator raw material crushing equipment. Background Technology

[0002] Accelerators are admixtures added to concrete that enable it to set and harden rapidly. The main component of accelerators is alumina clinker (clinker made by calcining bauxite, soda ash, and quicklime in a certain proportion) which is then finely ground. Other types also exist, such as alkaline earth metal carbonates and hydroxides, sodium silicate, potassium silicate, sodium aluminate, potassium aluminate, and alkali-free liquid accelerators.

[0003] Existing quick-setting agent raw material crushing equipment usually uses grinding to obtain relatively fine raw material powder. However, since quick-setting agents are reactive, drastic temperature changes can have a certain impact on quick-setting agent raw materials, generating impurities.

[0004] A Chinese utility model patent, titled "A Mixing Device for the Production of Concrete Accelerators" and with publication number CN215782935U, includes a motor mounted at the top of a mixing tank and connected to a mixing rod. A liquid raw material silo is fixed to the top of the mixing tank. A viewing window is located on the inner wall of the mixing tank, and a feed box is fixed to the top of the mixing tank. This utility model solves the problem of easy clogging of the feed inlet on the inner wall of the mixing tank and the problem of crushing solid raw materials through the coordination of multiple parts.

[0005] Although this invention can ensure that the quick-setting agent raw materials are fully mixed, its crushing effect is not good and it cannot generate quick-setting agent raw material powder. Utility Model Content

[0006] The purpose of this application is to provide a crushing device for accelerator raw materials, which solves the technical problem of rapid crushing of accelerator raw materials and ensuring crushing quality.

[0007] To solve the above-mentioned technical problems, the solution adopted in this application is as follows:

[0008] A crushing device for quick-setting agent raw materials includes a crushing barrel, which includes a barrel body, an inlet at the top of the barrel body, and an outlet at the bottom of the barrel body.

The crushing component arranged at the bottom is fixed in the barrel body, and the crushing component arranged at the top is vertically slidably connected to the barrel body and fixedly connected to the stamping end of the stamping component. The stamping component is arranged at the top of the barrel body.

[0010] Preferably, a fine crushing cylinder is provided below the crushing component, and a crushing component is provided inside the fine crushing cylinder.

[0011] Preferably, the fine crushing cylinder is connected to a rotating structure, which is located inside the cylinder, and the fine crushing cylinder rotates coaxially with respect to the crushing component.

[0012] Preferably, the fine grinding cylinder includes a fine grinding inner cylinder and filter holes, the lower part of the fine grinding inner cylinder has several filter holes, and the inner wall of the fine grinding inner cylinder has a rough, raised structure.

[0013] Preferably, an air jet assembly is provided on the outside of the fine crushing cylinder, and the air jet direction of the air jet assembly is towards the bottom of the fine crushing cylinder.

[0014] Preferably, the bottom of the crushing cylinder is provided with an outlet component, which includes an inclined plate with several inclined slots.

[0015] Preferably, the rolling assembly includes a stamping plate, which is disposed on the inner wall of the barrel, and a plurality of stamping columns are vertically arranged on the stamping surface of the stamping plate.

[0016] The stamping plate has several through holes, which are located between adjacent stamping columns.

[0017] Preferably, the fine grinding inner cylinder has an hourglass-shaped structure, and the top surface of the fine grinding inner cylinder is fixedly connected to the surface of the stamping plate. Several holes on the stamping plate are located in the projection of the hourglass-shaped structure of the fine grinding inner cylinder.

[0018] Preferably, the rotating structure includes a gear ring, which is coaxially and fixedly sleeved on the outer wall of the fine grinding inner cylinder. The gear ring meshes with a gear, which is coaxially and fixedly mounted on the drive shaft of the first motor. The first motor is fixed to the inner wall of the cylinder.

[0019] Preferably, the grinding assembly includes a second motor, which is located below the barrel. The drive shaft of the second motor is fixedly connected to a rotating shaft, which passes through the bottom of the fine grinding inner cylinder. A blade is provided on the rotating shaft, and the blade is located at the bottom of the fine grinding inner cylinder.

[0020] Preferably, a perforated sleeve is provided on the bottom surface inside the fine grinding inner cylinder, and the perforated sleeve is coaxially sleeved on the outside of the blade of the rotating shaft.

[0023] Preferably, the scraper rotates relative to the inclined plate via a rotating structure connected to the fine crushing cylinder.

[0024] The technical solution of this application has at least the following advantages and beneficial effects:

[0025] In this invention, by setting a rolling component and a stamping component, the quick-setting agent raw material is initially rolled and crushed to reduce the size of the raw material, making it easier to crush into powder in the subsequent process. In addition, the rolling action will not generate too much frictional heat, thus avoiding excessive crushing temperature.

[0026] In this invention, by setting a rotating fine crushing cylinder and a mixing component, the small particles of quick-setting agent raw materials are further crushed and ground in a double manner, thereby quickly generating powder.

[0027] In this invention, by setting up an air jet assembly and an outlet assembly, the temperature is reduced during the grinding of the fine crushing cylinder by blowing air, thus avoiding excessive grinding temperature. The floating raw material powder in the cylinder is also sucked out and collected by negative pressure, while a one-way channel is used to prevent the floating powder from scattering everywhere.

[0037] Example

[0038] Please refer to Figures 1-5 This utility model provides a crushing device for quick-setting agent raw materials, including a crushing barrel 1, a crushing component 2, a stamping component 3, a fine crushing cylinder 4, a rotating structure 5, a support plate 6, a mixing component 7, an air jet component 8, and an outlet component 9.

[0039] Furthermore, the crushing barrel 1 is used to hold the quick-setting agent raw materials that need to be crushed. The crushing barrel 1 includes a barrel body 101, a feed inlet 102, and a discharge outlet 103.

[0040] The upper side wall of the barrel 101 is provided with a feed inlet 102, and the lower side wall of the barrel 101 is provided with a discharge outlet 103.

[0041] Furthermore, two layers of compaction components 2 are vertically arranged at the top of the barrel 101, with the compaction ends of the two layers of compaction components 2 facing each other, and the feed inlet 102 is located between the two layers of compaction components 2, so that the quick-setting agent raw material is introduced here for preliminary compaction.

[0042] In the two-layer rolling assembly 2, the rolling assembly 2 located below is fixed inside the barrel 101, while the rolling assembly 2 located above is vertically slidably connected to the barrel 101 and fixedly connected to the stamping end of the stamping assembly 3, which is located at the top of the barrel 101.

[0043] The stamping assembly 3 is set as a stamping electric cylinder, and the stamping direction is vertical.

[0044] Preferably, when larger particles of the accelerator raw material enter the barrel 101, preliminary crushing is performed to facilitate rapid crushing into finer powder, forming smaller particles that are easier to form subsequent powder. Furthermore, since the accelerator is an additive, the temperature during crushing and grinding needs to be controlled. Using a pressing crushing method ensures that the contact time between the crushing component 2 and the raw material is very short during crushing, preventing the generation of high temperatures during the preliminary crushing process that could affect the quality of the accelerator raw material.

[0045] Please refer to Figure 2 and Figure 3 In this embodiment, the rolling assembly 2 includes a stamping plate 201, a stamping column 202, and a perforation 203.

[0046] Specifically, the stamping plate 201 is disposed on the inner wall of the barrel 101. The upper stamping plate 201 is slidably disposed with respect to the inner wall of the barrel 101, and the lower stamping plate 201 is fixedly disposed with respect to the inner wall of the barrel 101, so that the upper stamping plate 201 performs vertical stamping work through the stamping assembly 3.

[0047] Several stamping columns 202 are vertically arranged on the stamping surface of the stamping plate 201, and several leakage holes 203 are penetrating on the stamping plate 201 located below, with the leakage holes 203 located between adjacent stamping columns 202.

[0048] The raw material is crushed into smaller particles by a smaller contact area, reducing the heat generated during stamping friction. The upper and lower opposing stamping columns 202 are staggered to repeatedly crush the raw material until the size of the quick-setting agent raw material particles is smaller than the size of the leakage hole 203, and then leaks into the lower part of the hole 203 for more fine crushing.

[0049] Furthermore, a fine crushing cylinder 4 is provided below the crushing component 2 to collect the initially crushed quick-setting agent raw material particles. A crushing component 7 is provided inside the fine crushing cylinder 4 to further crush the quick-setting agent raw material particles. The fine crushing cylinder 4 is connected to a rotating structure 5, which is located inside the barrel body 101, so that the fine crushing cylinder 4 rotates coaxially with respect to the crushing component 7.

[0050] Please refer to Figure 2 In this embodiment, the fine crushing cylinder 4 includes a fine grinding inner cylinder 401 and a filter hole 402.

[0051] Specifically, the fine grinding inner cylinder 401 has an hourglass-shaped structure. The top surface of the fine grinding inner cylinder 401 is rotatably connected to the surface of the stamping plate 201. Several holes 203 on the stamping plate 201 are located in the projection of the hourglass-shaped structure of the fine grinding inner cylinder 401.

[0052] The raw materials passing through the 203 will enter the interior of the fine grinding inner cylinder 401 and be guided to the lower part of the hourglass-shaped structure through the upper part. The lower part of the hourglass-shaped structure is a conical structure. When the grinding component 7 in the fine grinding inner cylinder 401 grinds the raw materials, the floating raw material powder is blocked by the conical structure, which slows down the diffusion of the floating raw material powder.

[0053] The lower part of the fine grinding inner cylinder 401 has several filter holes 402 (that is, filter holes 402 are opened at the bottom and side wall of the fine grinding inner cylinder 401), and the inner wall of the fine grinding inner cylinder 401 has a rough protruding structure.

[0054] Preferably, the quick-setting agent raw material particles crushed by the crushing component 7 are thrown to the outermost part of the fine grinding inner cylinder 401 by centrifugal force, and come into contact with the rough protruding inner wall of the relatively rotating fine grinding inner cylinder 401, causing the quick-setting agent raw material particles to collide and wear into powder, and then filter out through the filter hole 402 on the fine grinding inner cylinder 401 to obtain the quick-setting agent powder that meets the requirements.

[0055] Please refer to Figure 2 and Figure 4 In this embodiment, the rotating structure 5 includes a gear ring 501, a gear 502, and a first motor 503.

[0056] Specifically, the gear ring 501 is coaxially fixedly sleeved on the outer wall of the fine grinding inner cylinder 401. The gear ring 501 meshes with the gear 502. The gear 502 is coaxially fixed on the drive shaft of the first motor 503. The first motor 503 is fixed on the inner wall of the barrel 101. When the first motor 503 works, the gear ring 501 will mesh and rotate, driving the fine grinding inner cylinder 401 to rotate.

[0057] The inner grinding cylinder 401 is fitted with a support plate 6, which is fixed inside the barrel body 101. The toothed ring 501 and the gear 502 slide against the top surface of the support plate 6, thereby supporting the entire fine crushing cylinder 4 and the rotating structure 5 through the support plate 6.

[0058] Please refer to Figure 2 In this embodiment, the pulverizing component 7 includes a second motor 701, a rotating shaft 702, a blade 703, a perforated sleeve 704, and a slot 705.

[0059] Specifically, the second motor 701 is fixedly installed inside the lower part of the barrel 101. The drive shaft of the second motor 701 is fixedly connected to one end of the rotating shaft 702. The rotating shaft 702 passes through the bottom of the fine grinding inner cylinder 401. The other end of the rotating shaft 702 rotates and abuts against the bottom surface of the stamping plate 201 to provide support for the stamping plate 201. A blade 703 is provided on the rotating shaft 702. The blade 703 is located at the bottom inside the fine grinding inner cylinder 401. The rotating shaft 702 drives the blade 703 to rotate and cut the quick-setting agent raw material particles in the fine grinding inner cylinder 401.

[0060] A perforated sleeve 704 is fixedly installed on the bottom surface inside the fine grinding inner cylinder 401. The perforated sleeve 704 is coaxially sleeved on the outside of the blade 703 of the rotating shaft 702. Several perforations 203 are penetrating the perforated sleeve 704. When the quick-setting agent raw material is cut and thrown out by the blade 703, it will be blocked by the perforated sleeve 704, so that the quick-setting agent raw material continues to return to the rotating blade 703 to be cut until the quick-setting agent raw material can pass through the perforation 203 of the perforated sleeve 704, so as to avoid the quick-setting agent raw material rubbing against the inner wall of the fine grinding inner cylinder 401 being too large and the friction time being too long.

[0061] The bottom of the perforated sleeve 704 is also provided with a groove 705. When too much quick-setting agent material accumulates in the perforated sleeve 704, it will affect the rotation of the blade 703. Therefore, a groove 705 is provided at its bottom. When too much quick-setting agent material accumulates, the quick-setting agent material at the bottom of the perforated sleeve 704 will be thrown out from the groove 705 onto the inner wall of the fine grinding inner cylinder 401 for fine grinding.

[0062] Furthermore, an air jet assembly 8 is provided on the outside of the fine crushing cylinder 4, and the air jet direction of the air jet assembly 8 is towards the bottom of the fine crushing cylinder 4.

[0063] The jet assembly 8 consists of an air pipe and a pump head, and is used to blow air onto the lower part of the outer wall of the fine grinding inner cylinder 401 to cool the cylinder wall of the fine grinding inner cylinder 401.

[0064] Because the outer wall of the fine grinding inner cylinder 401 is blown by the jet assembly 8, the wind speed is high, resulting in a lower external air pressure. However, there is no rapid airflow inside the fine grinding inner cylinder 401, and the wind speed is low, resulting in a higher internal air pressure. This creates a pressure difference between the inside and outside of the fine grinding inner cylinder 401. The raw material powder floating inside the cylinder is subjected to pressure and will be carried to the outside of the cylinder for easy collection.

[0065] Furthermore, the bottom of the fine crushing cylinder 4 is provided with an outlet component 9. The outlet component 9 and the jet component 8 work together to allow the raw material powder blown out by the jet component 8 to pass through in one direction and not to be scattered everywhere due to the airflow returning.

[0066] Please refer to Figure 5 In this embodiment, the outlet component 9 includes a bevel plate 901 and a scraper 902.

[0067] Specifically, the inclined plate 901 is fixedly installed on the inner wall of the barrel 101, and several inclined slots 705 are provided through the inclined plate 901. Multiple scrapers 902 are fixedly installed on the bottom surface of the fine crushing cylinder. The scrapers 902 rotate relative to the inclined plate 901 through the rotating structure 5 connected to the fine crushing cylinder, and the scrapers 902 are in contact with the plate surface of the inclined plate 901.

[0068] The raw material powder blown out by the jet assembly 8 will be blown to the discharge port 103 through the inclined opening, while the inclined slot 705 will block some of the returning raw material powder. In addition, the raw material powder filtered out of the filter hole 402 of the fine grinding inner cylinder 401 will also be scraped into the inclined opening of the inclined plate 901 by the rotating scraper 902 and enter the discharge port 103.

[0069] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description. The scope of this utility model is defined by the appended claims.
