Description

Technical Field

[0001] This utility model relates to the field of powder packaging technology, and in particular to a powder unblocking structure for a potassium persulfate compound powder filling equipment. Background Technology

[0002] After the production of potassium persulfate compound powder is completed, the final step is usually filling the finished product. However, due to the inherent properties of potassium persulfate compound powder, adhesion and clumping are prone to occur during filling.

[0003] In particular, the filling head section of potassium persulfate compound powder filling equipment is problematic. The filling head (filling tube) is typically a thin pipe, and its outer end is often exposed to air, coming into contact with moisture. This exacerbates the adhesion and clumping of the potassium persulfate compound powder. This adhered and clumped powder can easily remain on the inner wall of the filling head (filling tube) after filling, even clogging the filling head and causing adverse effects.

[0004] Currently, the main solution for residual powder or blockage in filling heads is to coat the inner wall of the filling head (filling tube) with a special material coating, such as Teflon, to increase its smoothness. However, this method only improves the adhesion of potassium bisulfate compound powder, but cannot eliminate it completely. Therefore, regular cleaning is still necessary, such as using airflow to blow away the residual potassium bisulfate compound powder from the inner wall of the filling head (filling tube).

[0005] However, this airflow purging method easily blows the residual potassium bisulfate compound powder everywhere, which not only causes waste, but also makes it difficult to handle the scattered potassium bisulfate compound powder, affecting the cleanliness of the production (filling) equipment. Utility Model Content

[0006] In view of this, the purpose of this utility model is to propose a powder unblocking structure for a potassium persulfate compound powder filling equipment, so as to solve the problems of potassium persulfate compound powder residue and residual potassium persulfate compound powder dispersion in the prior art.

[0007] To achieve the above objectives, this utility model provides a powder unblocking structure for a potassium persulfate compound powder filling device, including a filling chamber and a filling bucket and a replenishment bucket disposed inside the filling chamber. The powder unblocking structure further includes:

[0008] A filling pipe is provided at the lower end of the filling tank and the replenishment tank, and the filling pipe is fixedly connected to the respective filling tank or replenishment tank through a connecting part;

[0009] A scraper is slidably connected to the inner wall of the filling pipe. The top of the scraper is located in the connecting part, and the connecting part is also provided with a driving mechanism for driving the scraper to rotate along the inner wall of the filling pipe.

[0010] Furthermore, the volume of the filling bucket is larger than that of the replenishment bucket, and the inner diameter of the filling pipe at the bottom of the filling bucket is larger than that of the filling pipe at the bottom of the replenishment bucket.

[0011] Furthermore, the filling chamber is fixedly connected to the base platform, and the base platform is also equipped with a conveyor line, which is located directly below the filling pipe.

[0012] Furthermore, the filling pipe is connected to the outlet of its respective filling or replenishing tank, and an electromagnetic valve is also provided in the filling pipe.

[0013] Furthermore, the driving mechanism includes an annular groove disposed within the connecting portion, and the upper end of the scraper is provided with an expansion portion, which is slidably connected within the annular groove.

[0014] Furthermore, an air supply pipe is fixedly connected to the connecting part. The outer end of the air supply pipe is connected to an external air source and an air pump, while the inner end of the air supply pipe is connected to an annular groove.

[0015] Furthermore, the connecting part is also provided with an airflow channel, and the two ends of the airflow channel are respectively connected to the air supply pipe and the annular groove.

[0016] Furthermore, a permanent magnet is provided at the connection between the scraper and the inner wall of the filling tube, and the filling tube is made of magnetic metal material.

[0017] The beneficial effects of this utility model are as follows: 1. Large-dose potassium bisulfate compound powder is filled quickly and efficiently using a filling tank, and small-dose material is replenished using a replenishment tank to ensure accurate dosage. Furthermore, the filling pipe connected to the lower end of the filling tank and the replenishment tank serves as the filling head, which is less prone to clogging compared to traditional filling heads.

[0018] 2. A scraper is installed inside the filling pipe, and the scraper is slidably connected to the inner wall of the filling pipe. After each filling, the scraper rotates along the inner wall of the filling pipe to effectively scrape off the potassium bisulfate compound powder remaining on the inner wall of the filling pipe, allowing it to fall into the potassium bisulfate compound powder packaging box. This not only avoids waste but also effectively solves the problem of potassium bisulfate compound powder residue in the filling pipe, while preventing the residual potassium bisulfate compound powder from scattering everywhere.

[0019] 3. The scraper is driven by blowing air into the annular groove through an air supply pipe and airflow channel. The upper end of the scraper has an expansion section that slides within the annular groove, resulting in a simple and convenient structure. Additionally, a permanent magnet is installed at the connection point between the scraper and the inner wall of the filling pipe, and the filling pipe is made of magnetic metal. This ensures the scraper remains in close contact with the inner wall of the filling pipe, guaranteeing effective scraping. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] The first aspect of this utility model is as follows: Figure 1 , Figure 2 and Figure 3 As shown, in order to efficiently and accurately fill potassium bisulfate compound powder, a filling chamber 103 is provided on the base 101. A conveyor line 102 is also provided on the base 101, and the conveyor line 102 is located directly below the filling pipe 106.

[0031] The filling chamber 103 is equipped with a filling tank 104 and a replenishing tank 105. The filling tank 104 is used for filling large doses of potassium bisulfate compound powder quickly and efficiently, and the replenishing tank 105 is used for replenishing small doses of material to ensure accurate dosage.

[0032] A filling pipe 106 is provided at the lower end of the filling tank 104 and the replenishing tank 105. The filling pipe 106 is fixedly connected to the respective filling tank 104 or replenishing tank 105 through the connecting part 107. The filling pipe 106 is connected to the outlet of the respective connected filling tank 104 or replenishing tank 105, and a solenoid valve 109 is also provided in the filling pipe 106.

[0033] Preferably, the volume of the filling tank 104 is larger than that of the replenishing tank 105, and the inner diameter of the filling pipe 106 at the bottom of the filling tank 104 is larger than that of the filling pipe 106 at the bottom of the replenishing tank 105.

[0034] The filling head is made by using a filling pipe 106 connected to the lower end of the filling tank 104 and the replenishment tank 105. Compared with traditional filling heads, it is less prone to clogging.

[0035] The first aspect of this utility model is as follows: Figure 3 , Figure 4 and Figure 5As shown, conventional solutions for residual powder or blockage in filling heads mainly involve coating the inner wall of the filling head (filling tube) with a special material, such as Teflon, to increase its smoothness. However, this method only improves the adhesion of potassium bisulfate compound powder, but cannot eliminate it completely. Therefore, regular cleaning is still required, such as using airflow to blow away the residual potassium bisulfate compound powder on the inner wall of the filling head (filling tube). However, this airflow blowing method easily scatters the residual potassium bisulfate compound powder everywhere, causing waste and making the scattered powder difficult to handle, thus affecting the cleanliness of the production (filling) equipment.

[0036] Therefore, in this embodiment, a scraper 111 is slidably connected to the inner wall of the filling pipe 106, and the top of the scraper 111 is located in the connecting part 107. The connecting part 107 is also provided with a driving mechanism for driving the scraper 111 to rotate along the inner wall of the filling pipe 106.

[0037] After each filling, the scraper 111 rotates once along the inner wall of the filling tube 106, effectively scraping off the potassium bisulfate compound powder remaining on the inner wall of the filling tube 106 and allowing it to fall into the potassium bisulfate compound powder packaging box. This not only avoids waste but also effectively solves the problem of potassium bisulfate compound powder residue in the filling tube 106, while preventing the residual potassium bisulfate compound powder from scattering everywhere.

[0038] The driving mechanism includes an annular groove 110 within the connecting portion 107. An expansion portion is provided at the upper end of the scraper 111, which is slidably connected within the annular groove 110. An air supply pipe 108 is also fixedly connected to the connecting portion 107. The outer end of the air supply pipe 108 is connected to an external air source and air pump, while the inner end of the air supply pipe 108 is connected to the annular groove 110. An airflow channel 112 is also provided inside the connecting portion 107, with both ends of the airflow channel 112 connected to the air supply pipe 108 and the annular groove 110, respectively.

[0039] Preferably, a permanent magnet is provided at the connection between the scraper 111 and the inner wall of the filling tube 106, and the filling tube 106 is made of magnetic metal material.

[0040] The scraper 111 is driven by air blowing through the air supply pipe 108 and airflow channel 112 into the annular groove 110. The upper end of the scraper 111 has an expansion section that is slidably connected within the annular groove 110. This design is simple and easy to use. Furthermore, a permanent magnet is provided at the connection point between the scraper 111 and the inner wall of the filling pipe 106, and the filling pipe 106 is made of a magnetic metal material. This ensures that the scraper 111 remains in close contact with the inner wall of the filling pipe 106, guaranteeing effective scraping.

[0041] In summary, this invention utilizes a filling tank 104 for large-dose filling of potassium bisulfate compound powder, which is fast and efficient. A replenishment tank 105 is used for small-dose replenishment, ensuring accurate dosage. Furthermore, a filling pipe 106 connected to the lower ends of the filling tank 104 and replenishment tank 105 serves as the filling head, making it less prone to clogging compared to traditional filling heads. A scraper 111 is installed inside the filling pipe 106, and the scraper 111 is slidably connected to the inner wall of the filling pipe 106. After each filling, the scraper 111 rotates once along the inner wall of the filling pipe 106, effectively scraping off any residual potassium bisulfate compound powder and allowing it to fall into the potassium bisulfate compound powder packaging box. This not only avoids waste but also effectively solves the problem of residual potassium bisulfate compound powder in the filling pipe 106, while preventing the residual powder from scattering. The scraper 111 is driven by air blowing through the air supply pipe 108 and airflow channel 112 into the annular groove 110. The upper end of the scraper 111 has an expansion section that is slidably connected within the annular groove 110. This design is simple and easy to use. Furthermore, a permanent magnet is provided at the connection point between the scraper 111 and the inner wall of the filling pipe 106, and the filling pipe 106 is made of a magnetic metal material. This ensures that the scraper 111 remains in close contact with the inner wall of the filling pipe 106, guaranteeing effective scraping.
