Description

Technical Field

[0001] This utility model relates to the field of silo unclogging technology, specifically a pulse unclogging nozzle for silos. Background Technology

[0002] The silo unblocking system is primarily used to resolve issues such as material accumulation, clumping, or blockage in silos, ensuring smooth material flow. Utilizing pulse unblocking nozzle technology, high-pressure gas pulses are injected into the silo's inner wall at regular intervals or as needed, rapidly loosening or dispersing blockages and preventing material stagnation during storage or transport. Pulse unblocking nozzles typically work in conjunction with pulse solenoid valves and air supply systems to form a highly efficient unblocking system, widely used in silo management in industries such as cement, fertilizer, and grain, significantly improving material flowability and equipment productivity.

[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Due to prolonged contact between the nozzle and the blockage, the blockage material may flow into the nozzle, leading to blockage or damage; 2. The installation of the pulse unclogging nozzle may be cumbersome and inconvenient for workers. The whole process is time-consuming and labor-intensive, reducing labor costs while increasing time costs. Utility Model Content

[0004] The purpose of this utility model is to provide a pulse unclogging nozzle for a silo, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a pulse unclogging nozzle for a silo, comprising an electromagnetic pulse valve, a first connecting pipe mounted on the top of the electromagnetic pulse valve by a first bolt and nut, a second connecting pipe mounted on the outer side of the first connecting pipe, a third connecting pipe mounted on the top of the first connecting pipe by a second bolt and nut, a nozzle assembly mounted on the top of the third connecting pipe, and an mounting plate mounted on the outside of the nozzle assembly.

[0005] The nozzle assembly includes a sleeve installed inside the third connecting pipe. A nozzle tube is fixedly connected to the top of the sleeve. Springs are evenly installed inside the nozzle tube. A connecting frame is installed on the top of the springs. Support columns are fixedly connected around the top of the connecting frame. Limit blocks are fixedly connected to the lower outer part of the support columns. A connecting cover is fixedly connected to the top of the support columns.

[0006] More preferably, the mounting plate has rounded corners on all four sides.

[0007] More preferably, the mounting plate has a first slot around its top perimeter.

[0008] More preferably, a flange ring is installed at one end of the second connecting pipe, and a second slot is evenly provided around one side of the flange ring.

[0009] More preferably, the upper inner side of the third connecting pipe is provided with an internal thread groove, and the outer side of the sleeve is provided with an external thread groove.

[0011] More preferably, a first groove is provided on the upper inner side of the nozzle tube, and a second groove is provided around the inner wall of the nozzle tube that matches the external dimensions and structure of the limiting block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, a nozzle assembly is added, which allows the connecting cover to be lifted by pulse unblocking. Under the limiting action of the second groove and the elastic deformation of the spring, the connecting cover can be retracted after being lifted to a certain range, thereby covering the nozzle tube and ensuring that blockages do not enter the nozzle tube and cause blockages or damage. This increases the unblocking efficiency and also extends the service life.

[0014] In this invention, an internal thread groove and an external thread groove are added, which allows for quick installation of the nozzle assembly and the third connecting pipe. The whole process is relatively easy, reducing labor costs and saving time. In addition, an installation plate is added to facilitate the installation of the device, increasing its stability during use and effectively preventing it from falling off.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: a pulse unclogging nozzle for a silo, including an electromagnetic pulse valve 1, a first connecting pipe 3 installed on the top of the electromagnetic pulse valve 1 by a first bolt and nut 2, a second connecting pipe 4 installed on the outer side of the first connecting pipe 3, a third connecting pipe 6 installed on the top of the first connecting pipe 3 by a second bolt and nut 5, a nozzle assembly 7 installed on the top of the third connecting pipe 6, and an mounting plate 8 installed on the outside of the nozzle assembly 7.

[0023] The nozzle assembly 7 includes a sleeve 701 installed inside the third connecting pipe 6. A nozzle pipe 702 is fixedly connected to the top of the sleeve 701. Springs 703 are evenly installed inside the nozzle pipe 702. A connecting frame 704 is installed on the top of the springs 703. Support columns 705 are fixedly connected around the top of the connecting frame 704. Limiting blocks 706 are fixedly connected to the lower outer part of the support columns 705. A connecting cover 707 is fixedly connected to the top of the support columns 705.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the mounting plate 8 has rounded corners on all four sides; this design reduces the risk of injury to workers during installation or transportation from accidental impacts compared to sharp edges, thus improving safety.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the mounting plate 8 has a first slot around its perimeter. This design allows workers to pass the fixing bolts through the first slot to install the device, thereby increasing its stability during use and effectively preventing it from falling off.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a flange ring is installed at one end of the second connecting pipe 4, and a second slot is evenly opened around one side of the flange ring. This design allows one end of the second connecting pipe 4 to be connected and installed to the air compressor through the flange ring, and the fixing bolts are passed through the second slot, thereby increasing the sealing and stability after installation.

[0027] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the upper inner side of the third connecting pipe 6 is provided with an internal thread groove, and the outer side of the sleeve 701 is provided with an external thread groove. This design allows workers to quickly install the nozzle assembly 7 with the third connecting pipe 6. The whole process is relatively easy, reducing labor costs and saving time.

[0028] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the spring 703 and the connecting frame 704 form an elastic structure. Through this design, the connecting frame 704 can retract through the elastic deformation of the spring 703, so that the connecting cover 707 covers the nozzle tube 702, thereby ensuring that the blockage will not enter the nozzle tube 702 and cause blockage and damage. This increases the unblocking efficiency and also increases the service life.

[0029] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a first groove is provided on the upper inner side of the nozzle tube 702, and a second groove is provided around the inner wall of the nozzle tube 702, which is consistent with the external dimensions of the limiting block 706. Through this design, the spring 703 is evenly installed on the top of the first groove. When the airflow passes through the electromagnetic pulse valve 1 to clear the blockage, the connecting cover 707 will rise. And through the limiting block 706 and the second groove, the rising height is consistent and limited, which prevents the connecting cover 707 from accidentally falling off. At the same time, it also makes the efficiency of the light flow more uniform.

[0030] The usage and advantages of this utility model: This pulse unclogging nozzle for silos operates as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, firstly, the electromagnetic pulse valve 1 is installed to the first connecting pipe 3 using the first bolt and nut 2. Then, the first connecting pipe 3 is installed to the third connecting pipe 6 using the second bolt and nut 5. Next, the air compressor is connected to one end of the second connecting pipe 4, and the fixing bolts are passed through the second slots opened in the flange ring for installation, thereby increasing the sealing and stability after installation. Then, the third connecting pipe 6 is installed to the nozzle assembly 7 by rotation. Finally, the fixing bolts are passed through the first slots opened around the top of the mounting plate 8, thus securing the entire device. When the equipment is installed and the electromagnetic pulse valve 1 is opened, the hopper can be cleared. At this time, the connecting cover 707 is raised under the action of airflow, so that the airflow passes between the support columns 705 to clear the blockage. Under the limiting action of the limiting block 706 and the second groove opened around the inner wall of the nozzle tube 702, the height of the rise is consistent and limited. The spring 703 will also undergo elastic deformation. After the pulse clearing, the connecting cover 707 will retract through the elastic deformation of the spring 703, thereby covering the nozzle tube 702 and preventing the blockage from entering the nozzle tube 702.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
