Description

Technical Field

[0001] This utility model relates to the field of solid feeding technology, specifically to an anti-clogging solid feeding device. Background Technology

[0002] Solid feeders are core auxiliary equipment in industries such as chemical, food, pharmaceutical, building materials, and metallurgy. They are mainly responsible for transporting solid materials (such as powders, granules, and small lumps, such as flour, fertilizer granules, traditional Chinese medicine powder, and ore fragments) from storage bins, hoppers, and other containers to subsequent production equipment (reaction kettles, crushers, conveying pipelines, molding machines, etc.). They are the "first line of defense" to ensure continuous production.

[0003] After searching, the existing technology (application number: CN218260928U) describes "an anti-clogging feeding device that drives the stirring rod to rotate and stir the material through the stirring component, and blows airflow to the side wall of the material cylinder through the blower component to assist feeding, while using the airflow to push the swing plate to change the inner wall structure to avoid bridging phenomenon".

[0004] This utility model mainly relies on airflow disturbance and a single agitation structure to alleviate clogging. Although it can solve some bridging problems, there is a risk of material splashing due to air pressure imbalance. In addition, it does not have a graded filtration structure, so it cannot accurately process materials of different particle sizes. Furthermore, it lacks special cleaning components for the filter screen and cylinder wall. Long-term use is prone to reduced efficiency due to material adhesion. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging solid feeding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-clogging solid feeding device, comprising: a support structure including legs, four sets of legs, and a fixing block at the bottom of the legs; a mixer arranged on the support structure, including a material cylinder, with a discharge hole at the bottom of the material cylinder; a machine cover arranged on the top of the mixer, including a top cover, with a feeding port on the top cover; a motor arranged on the machine cover; and a discharge adjustment structure arranged at the bottom of the mixer for discharging material.

[0007] As a further description of the above technical solution:

[0008] The support structure includes: a fixing block with a through hole for connecting to the ground; and a support platform set on top of the legs for fixing the mixer.

[0009] As a further description of the above technical solution:

[0010] Two sets of threaded holes are provided at the top of the barrel.

[0011] As a further description of the above technical solution:

[0013] As a further description of the above technical solution:

[0014] There are two sets of rotating scrapers. One set is arranged above the first filter screen and the other set is arranged above the second filter screen. Both sets of rotating scrapers are connected to the rotating blade assembly.

[0015] As a further description of the above technical solution:

[0016] The machine cover includes: a top cover with two sets of through holes aligned with the threaded holes of the rotating blade assembly; and two sets of bolts that thread through the top cover and connect to the threaded holes of the barrel.

[0017] As a further description of the above technical solution:

[0018] The discharge adjustment structure includes: a control valve with a knob on one side for controlling the material discharge flow rate; discharge pipe one, one end of which is connected to the discharge hole at the bottom of the material cylinder and the other end of which is connected to the control valve; and discharge pipe two, which is connected to the control valve.

[0019] This utility model has the following beneficial effects:

[0020] 1. The material is crushed by a rotating blade assembly, and graded filtration is achieved in conjunction with a double-layer filter screen. At the same time, two sets of rotating scrapers clean the filter screen surface and the inner wall of the material cylinder, forming a synergistic mechanism of crushing, filtering and active cleaning.

[0029] Example 1:

[0030] like Figures 1 to 2As shown, this embodiment provides an anti-clogging solid feeding device, comprising: a support structure 1, including four sets of support legs 101, with a fixing block 102 at the bottom of each support leg 101; a mixer 2, arranged on the support structure 1, including a material cylinder 201, with a discharge hole at the bottom of the material cylinder 201; a cover 3, arranged on the top of the mixer 2, including a top cover 301, with a feed inlet 302 on the top cover 301; a motor 4, arranged on the cover 3; and a discharge adjustment structure 5, arranged at the bottom of the mixer 2 for discharging material.

[0031] In this embodiment, the mixing machine structure and the discharge adjustment structure constitute an anti-clogging solid feeding device according to this application.

[0032] It should also be noted that the solid feedstock in this application can be solid feedstock from the pharmaceutical industry, solid feedstock from the chemical industry, solid feedstock from the food processing industry, etc. Figure 1 In this embodiment, solid feed is used as an example of solid feed in the pharmaceutical industry. Of course, other types of solid feed can also adopt a similar structure, which will not be described in detail below.

[0033] Understandable, Figure 1 The solid feeding device is shown only schematically, and the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, solid feeding devices can also include, compared to Figure 1 More or fewer parts.

[0034] It should also be understood that the motors were all purchased from the market and are common knowledge in this field. They are only used and not modified, so the control methods and circuit connections will not be described in detail.

[0035] In addition, in this embodiment, solid material enters the material cylinder 201 from the stainless steel top cover 301 through the stainless steel feed port 302. The motor 4 drives the internal structure of the material cylinder 201 to operate. After processing, the material enters the discharge adjustment structure 5 through the discharge hole at the bottom of the material cylinder 201. The discharge adjustment structure 5 guides the material to be discharged.

[0036] Specifically, the support structure 1 includes: a fixing block 102 with a through hole for connecting to the ground; and a support platform 103, which is set on top of the support leg 101 for fixing the mixer 2.

[0037] In this embodiment, fasteners are used to pass through the through holes of the fixed block 102, which is made of cast iron, to fix the support leg 101, which is made of stainless steel, to the ground. The support platform 103, which is made of stainless steel, bears the overall weight of the mixer 2.

[0038] Specifically, the top of the barrel 201 has two sets of threaded holes.

[0039] As a preferred implementation, the threaded hole provides a positioning hole for the connection between the cover 3 and the barrel 201, ensuring accurate docking between the cover 3 and the barrel 201 and preventing material from leaking out from the joint.

[0040] Specifically, the mixer 2 includes: a rotating blade assembly 202, rotatably connected inside the material cylinder 201, and connected to the motor 4 at the top; a first filter screen 203, arranged inside the material cylinder 201 and penetrated by the rotating blade assembly 202, for preliminary filtration; a second filter screen 205, arranged inside the material cylinder 201 and penetrated by the rotating blade assembly 202, for secondary filtration; and two sets of rotating scrapers 206, arranged on both sides of the bottom of the rotating blade assembly 202, for scraping powder off the inner wall of the material cylinder 201.

[0041] In this embodiment, the motor 4 drives the rotating blade assembly 202, which is made of high-speed steel, to rotate and cut the material in the crushing cylinder 201. The material is filtered through the first filter screen 203, which is made of stainless steel, and the second filter screen 205, which is made of stainless steel. The second rotating scraper 206, which is made of wear-resistant steel, rotates with the rotating blade assembly 202 to prevent the material from clogging the cylinder 201.

[0042] Specifically, there are two sets of rotating scrapers 204, one set is arranged above filter screen 203 and the other set is arranged above filter screen 205. Both sets of rotating scrapers 204 are connected to the rotating blade assembly 202.

[0043] With this configuration, the rotating blade assembly 202 drives the rotating scraper 204 to rotate, scraping off the material adhering to the upper surface of the inner wall of the material cylinder 201.

[0044] Example 2:

[0045] Based on Example 1, in order to further prevent material spraying, a cover 3 is provided on the mixer 2;

[0046] Specifically, the machine cover 3 includes: a top cover 301 with two sets of through holes aligned with the threaded holes of the rotating blade assembly 202; and two sets of bolts 303 that thread through the top cover 301 and are threadedly connected to the threaded holes of the barrel 201.

[0047] Bolt 303 passes through the through hole of top cover 301 and engages with the threaded hole at the top of material cylinder 201, fixing top cover 301 to the top of material cylinder 201, realizing the detachable connection between machine cover 3 and mixer 2, facilitating maintenance of internal components and preventing material from escaping.

[0048] Example 3:

[0049] Based on Example 2, in order to further improve adjustability, a discharge adjustment structure 5 is arranged at the bottom of the mixer 2;

[0050] Specifically, the discharge adjustment structure 5 includes: a control valve 503 with a knob on one side for controlling the material discharge flow rate; a discharge pipe 1 501, one end of which is connected to the discharge hole at the bottom of the material cylinder 201, and the other end is connected to the control valve 503; and a discharge pipe 2 502, which is connected to the control valve 503.

[0051] In this embodiment, the processed material in the material cylinder 201 enters the discharge pipe 501, which is made of stainless steel, through the discharge hole. The opening of the control valve 503, which is made of cast iron, is adjusted by rotating the knob to control the material flow rate. The material then enters the discharge pipe 502, which is made of stainless steel, through the control valve 503 and is discharged.

[0052] In actual use, first place the fixing block 102 on the working ground, then use hex bolts 303 to pass through the through holes in the fixing block 102 and fix it to the ground to prevent the device from shifting during operation. Then start the motor 4, which drives the rotating blade assembly 202 to rotate at high speed in the material cylinder 201. Then pour solid material into the feed inlet 302, and it enters the material cylinder 201 from the feed inlet 302. The rotating blade assembly 202 rotates at high speed and cuts the solid material. A set of rotating scrapers on the filter screen 203... Plate 1 204 cleans the material adhering to the inner wall of the barrel 201, and then falls onto filter screen 1 203 for preliminary filtration. The material after preliminary filtration enters the next layer for secondary cutting. Another set of rotating scrapers 1 204 on filter screen 2 205 cleans the material adhering to the inner wall of the barrel 201, and then falls onto filter screen 2 205 for further filtration. Finally, it passes through filter screen 2 205 and falls into the discharge hole opened at the bottom of the barrel 201, enters discharge pipe 1 501, opens control valve 503, and then passes through discharge pipe 2 502 for discharge.

[0053] Its core advantages lie in its ability to pulverize large materials through rotating blades and achieve graded filtration through a double-layer filter screen. Combined with a scraper that actively cleans the filter screen surface and the inner wall of the cylinder, this synergistic mechanism of pulverization, filtration, and active cleaning can efficiently solve the clogging problem at its source. At the same time, the machine cover adopts a detachable connection design, which facilitates the maintenance of internal components. The support structure ensures that the overall structure is not easily displaced during operation through fixed components and a load-bearing platform. In addition, the adjustable discharge control structure can precisely adapt to the material requirements of subsequent processes. This combination achieves multiple advantages such as high efficiency in preventing clogging, convenient maintenance, stable operation, and controllable discharge.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
