Abstract
Description
Technical Field
[0001] This application relates to the field of emulsifier production technology, and in particular to a discharge structure for bagging emulsifiers. Background Technology
[0002] In the field of emulsifier production technology, with the continuous development of industrial production, the packaging requirements for emulsifier products are also increasing. Good packaging not only ensures the quality and performance of emulsifiers, preventing them from getting damp or deteriorating, but also facilitates product storage, transportation, and sales, improving production efficiency and economic benefits. Especially for powdered emulsifiers, which have a large market demand, optimizing their packaging is particularly important.
[0003] During bagging, an airtight packaging bag is typically placed over the discharge port of the material outlet structure. Compressed air pressure then forces the powdered emulsifier from the hopper into the packaging bag, completing the packaging process. This method is relatively simple and direct, utilizing the dynamic characteristics of compressed air to achieve a certain level of material transport and meet basic production needs for a limited period.
[0004] Because the packaging bag is airtight, the gas inside the bag gradually becomes saturated after some material is fed in. This makes it difficult to continue feeding powder into the bag smoothly, resulting in the weight of the material inside the bag failing to meet the standard requirements. Moreover, excessively high air pressure inside the bag can easily cause material leakage at the connection between the bag opening and the discharge port, leading to material waste. Utility Model Content
[0005] To facilitate the filling of powder into the bag, this application provides a discharge structure for bagging emulsifiers.
[0006] The discharging structure for emulsifier bagging provided in this application adopts the following technical solution:
[0007] A discharge structure for bagging emulsifiers includes a discharge pipe, a first return pipe, a hopper, and a feeding assembly. The feeding assembly is used to introduce the emulsifier in the hopper into the discharge pipe. The first return pipe is installed on the inner wall of the discharge pipe, and the inlet of the first return pipe faces the same direction as the discharge pipe. The outlet of the first return pipe is connected to the hopper through a second return pipe.
[0008] By adopting the above technical solution, the feeding component introduces the emulsifier in the hopper into the discharge pipe, thereby realizing the conveying of the emulsifier. The discharge pipe is equipped with a first return pipe, and the two ends of the second return pipe are connected to the hopper and the first return pipe, respectively. This allows excess gas and powder in the bag to return to the hopper through the second return pipe and the first return pipe during bagging, avoiding the impact of gas saturation in the bag on powder conveying, preventing the material weight from falling short of the standard, and reducing material leakage caused by air pressure issues.
[0009] Optionally, the second return pipe is connected to an air supply pipe, one end of which is connected to an external first air compressor.
[0010] By adopting the above technical solution, compressed air can be delivered to the second return pipe through the air supply pipe using the first compressed air compressor, thereby enhancing the power of the emulsifier in the first return pipe to flow back to the silo and improving the recovery efficiency of the emulsifier.
[0011] Optionally, an auxiliary feeding pipe is provided inside the discharge pipe, the air outlet of the auxiliary feeding pipe faces the same direction as the discharge outlet of the discharge pipe, and the air inlet of the auxiliary feeding pipe is connected to an external second compressed air machine.

[0013] Optionally, the feeding assembly includes a feeding pipe and an air outlet pipe. The feeding pipe is vertically installed at the bottom of the hopper. The feeding pipe, the air outlet pipe, and the discharge pipe are connected by a T-connector. The end of the air outlet pipe away from the T-connector is connected to an external third compressed air compressor.
[0014] By adopting the above technical solution, the feed pipe is installed vertically at the bottom of the silo, allowing the emulsifier to enter the three-way pipe by gravity. Then, through the air supply pipe connected to the feed pipe, compressed air is provided by an external third air compressor to blow the emulsifier in the feed pipe into the discharge pipe, thus achieving stable feeding.
[0015] Optionally, a detachable sleeve is fitted on the outer wall of the discharge pipe, and the opening of the packaging bag is fitted onto the outer wall of the sleeve.
[0016] By adopting the above technical solution, a detachable sleeve is fitted on the outer wall of the discharge pipe and the bag opening abuts against the outer wall of the sleeve, which makes it convenient to replace different specifications of sleeves to adapt to different bag opening sizes and facilitates bagging operations.
[0017] Optionally, the sleeve is threadedly connected to the outer wall of the discharge pipe.
[0018] By adopting the above technical solution, the sleeve is threadedly connected to the outer wall of the discharge pipe, making the sleeve detachable and securely installed, facilitating the replacement and cleaning of the sleeve, and enabling the packaging bag to be adapted to the discharge structure for bagging operations.
[0019] Optionally, the outer wall of the sleeve is threaded with bolts, which are used to abut against the outer wall of the discharge pipe.
[0020] By adopting the above technical solution, the threaded mounting bolts on the outer wall of the sleeve abut against the outer wall of the discharge pipe, which can achieve a stable connection and positioning between the sleeve and the discharge pipe, ensuring the relative position of the bag opening and the discharge pipe is stable, and facilitating the smooth loading of materials into the bag.
[0021] Optionally, the outer wall of the discharge pipe is provided with a rubber strip for abutting against the bolt.
[0022] By adopting the above technical solution, a rubber strip is installed on the outer wall of the discharge pipe to abut against the bolt, which can increase the friction and sealing between the bolt and the discharge pipe, further fix the position of the sleeve, prevent the sleeve from loosening, and avoid affecting the bagging operation due to the loose sleeve.
[0023] In summary, this application includes at least one of the following beneficial technical effects:

The two ends of the second return pipe are connected to the first return pipe in the silo and the discharge pipe, respectively, which allows the saturated gas in the bag to flow back to the silo, avoids the gas in the bag becoming saturated, solves the problem of the material being difficult to continue to be conveyed, and ensures that the material weight meets the standard.
[0025] 2. A detachable sleeve is fitted on the outer wall of the discharge pipe so that the bag opening abuts against the outer wall of the sleeve, which can enhance the sealing of the connection between the bag opening and the discharge port, further reduce material leakage, and enable the equipment to fill bags of different sizes.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0032] Example 1:
[0033] This application discloses a discharge structure for bagging emulsifiers.
[0034] Reference Figure 1 and Figure 2 A discharge structure for bagging emulsifiers includes a discharge pipe 1, a first return pipe 2, a hopper 3, and a feeding assembly 4. The hopper 3 is where the emulsifier is stored; it is typically a closed container with a certain volume. The hopper 3 can be made of metal to provide high strength and stability. The top of the hopper 3 has an inlet for adding emulsifier, and the bottom of the hopper 3 has an outlet for connecting to the feeding assembly 4.
[0035] The feeding assembly 4 includes a discharge pipe 41 and an air outlet pipe 42. The discharge pipe 41 is vertically installed at the bottom of the hopper 3 and connected to the discharge port. The discharge pipe 41 has a tubular structure to facilitate material conveying. The discharge pipe can be made of metal, which has good corrosion resistance and strength and can withstand the pressure of material flow; in other embodiments, the discharge pipe 1 can be made of plastic.
[0036] The discharge pipe 1, the air outlet pipe 42, and the feed pipe 41 are connected by a three-way pipe 43. The end of the air outlet pipe 42 away from the three-way pipe 43 is connected to an external third air compressor. When the emulsifier in the hopper 3 enters the feed pipe 41 and then the three-way pipe 43 by its own weight, the air outlet pipe 42 uses the pressure of the compressed air from the third air compressor to send the emulsifier into the discharge pipe 1 and into the bag body through the outlet of the discharge pipe 1.
[0037] Reference Figure 2 An auxiliary feeding pipe 5 is also provided on the inner wall of the discharge pipe 1. The extension direction of the auxiliary feeding pipe 5 is the same as the extension direction of the discharge pipe 1. The discharge pipe 1 has a first mounting hole 12. One end of the auxiliary feeding pipe 5 passes through the first mounting hole 12 and is connected to an external second compressed air machine. The other end of the auxiliary feeding pipe 5 is flush with the end of the discharge pipe 1 that has a discharge port. This can enhance the feeding power of the discharge pipe 1 during the filling process, better deliver the emulsifier into the packaging bag, and improve the bagging efficiency and effect.
[0038] The first return pipe 2 is installed on the inner wall of the discharge pipe 1, and one end of the first return pipe 2 is flush with the end of the discharge pipe 1 that has a discharge port. The other end of the first return pipe 2 is equipped with a second return pipe 21. The discharge pipe 1 has a second mounting hole 13, and the second return pipe 21 passes through the first return pipe 2 and the second mounting hole 13 and is connected to the hopper 3.
[0039] The first return pipe 2 and the second return pipe 21 are made of the same material as the discharge pipe 1. The diameters of the second return pipe 21 and the first return pipe 2 are both smaller than the diameter of the discharge pipe 1, so that the air and some material in the bag enter the hopper 3 through the first return pipe 2 and the second return pipe 21.
[0040] Reference Figure 1 In this embodiment, an air supply pipe 22 is provided in the middle of the return air pipe. The end of the air supply pipe 22 away from the second return material pipe 21 is connected to an external first compressed air machine. During the process of the return air pipe guiding excess material back to the silo 3, the airflow introduced by the air supply pipe 22 can increase the power of the material in the return air pipe, thereby assisting the material to return to the silo 3. Since the first compressed air machine, the second compressed air machine, and the third compressed air machine are all prior art, they will not be described in detail here.
[0041] The implementation principle of Embodiment 1 of this application is as follows:
[0042] During the process of the emulsifier in the discharge pipe 1 being sent into the packaging bag using compressed air, a vacuum negative pressure is formed in the first return pipe 2, allowing the compressed air and powder in the bag to enter the first return pipe 2, and then enter the hopper 3 through the second return pipe 21; and during the transportation of the powder in the second return pipe 21, the air supply pipe 22 can provide power for the powder to return to the hopper 3; thereby avoiding the impact of gas saturation in the bag on the powder conveying, preventing the material weight from falling short of the standard, and reducing material leakage caused by air pressure problems.
[0043] Example 2:
[0044] This application discloses a discharge structure for bagging emulsifiers.
[0045] Reference Figure 3 The difference between Embodiment 2 and Embodiment 1 is that: a detachable sleeve 6 is fitted on the outer wall of the discharge pipe 1. The sleeve 6 is generally a cylindrical structure and can be made of metal. Its outer diameter is slightly larger than that of the discharge pipe 1. When bagging, the bag opening can abut against the outer wall of the sleeve. The sleeve 6 is covered with the inner diameter of the bag opening and the outer diameter of the sleeve 6 is determined to prevent leakage during the bagging process.
[0046] In this embodiment, the sleeve 6 and the outer wall of the discharge pipe 1 can be connected by threads. This connection method is relatively firm and easy to disassemble and install, and sleeves 6 with different outer diameters can be replaced according to the inner diameter of the bag opening.
[0047] Example 3:
[0048] This application discloses a discharge structure for bagging emulsifiers.
[0049] Reference Figure 4The difference between Embodiment 3 and Embodiment 2 is that: the outer wall of the discharge pipe 1 is provided with an installation groove 11, the extension direction of the installation groove 11 is in the same direction as the extension direction of the discharge pipe 1, and a rubber strip 63 is pasted in the installation groove 11; the outer wall of the sleeve 6 is provided with a threaded hole 61, and a bolt 62 is threaded in the threaded hole 61, which is used to abut against the rubber strip 63.
[0050] Bolt 62 abuts against rubber strip 63, which can achieve a stable connection and positioning between sleeve 6 and discharge pipe 1; it can prevent sleeve 6 from sliding freely in discharge pipe 1 when the bag opening is connected to discharge pipe 1, thus increasing the stability of loading; and this installation method is simple, so that sleeve 6 can be quickly fixed to the outer wall of discharge pipe 1.
[0051] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
