Description

Technical Field

[0001] This utility model relates to the field of water jet shell breaking technology, and more specifically to a water jet shell breaking device. Background Technology

[0002] During anaerobic fermentation, organic matter tends to accumulate in the fermenter, forming a crust. This crust formation affects gas production efficiency and output. In existing technologies, the crust is mainly broken up by using a stirrer. However, the stirrer remains in a fixed position, resulting in a small range of action, long time consumption for breaking up the crust, and low efficiency.

[0003] Existing fermentation processes use water jet breaking devices to disperse the crusted material. For example, the water jet breaking device with prior art publication number CN221608086U has a large operating range and strong action capacity when using the water jet breaking device of this application, which can quickly and efficiently break the crust.

[0004] However, the existing technology described above still has the following problems in use: because the water jet shell-breaking device uses a water pump to achieve high-pressure water spraying, when workers are carrying the shell-breaking device, the nozzle may accidentally spray high-pressure water, causing injury, which poses a certain danger. Furthermore, when the exposed nozzle is removed from the material, the material can easily clog the nozzle, requiring a lot of time to clean, thus affecting the shell-breaking efficiency. Based on this, the present invention provides a water jet shell-breaking device. Utility Model Content

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a water jet shell-breaking device. By setting a protective cover on the outer wall of the shell-breaking head, it can not only protect the jet hole to avoid accidental injury to workers from the jet, but also automatically raise and lower the protective cover with the help of an electric push rod, making it convenient to adjust the height and very quick to use. In addition, when removing the shell-breaking head, sealing the jet hole with the protective cover can also reduce the clogging of the nozzle by materials, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water jet shell-breaking device, comprising a shell-breaking head, a water cavity inside the shell-breaking head, and multiple jet holes arranged in a ring array on the outer wall of the shell-breaking head, each jet hole communicating with the interior of the water cavity, and a nozzle fixedly installed inside each jet hole, one end of the nozzle penetrating the shell-breaking head and communicating with the interior of the water cavity, a water supply pipe fixedly installed on the top of the shell-breaking head, a protective cover fitted over the outer wall of the shell-breaking head, and the protective cover covering the outside of the water supply pipe, and an electric push rod and a guide rod respectively installed on both sides of the top of the protective cover.

[0007] In a preferred embodiment, a sealing cover is fixedly embedded on one side of the water pipe. The sealing cover is fitted over the outside of the electric push rod. A through hole is provided at the bottom of the sealing cover. The piston rod of the electric push rod passes through the through hole. A first rubber sealing ring is provided between the piston rod of the electric push rod and the through hole to fill the gap between them. This can improve the sealing performance of the sealing cover and reduce the risk of material contamination of the electric push rod to a certain extent.

[0008] In a preferred embodiment, a limiting block is fixedly embedded on the side of the water supply pipe away from the sealing cover. The bottom of the limiting block has a limiting hole that matches the guide rod. The top of the guide rod passes through the limiting hole and extends above the limiting block. When the electric push rod drives the protective cover to move up and down, the guide rod rises and falls in the limiting hole within the limiting block, thereby improving the stability of the lifting of the protective cover.

[0009] In a preferred embodiment, a sealing cover is detachably connected to the top of the sealing cover, and the top of the electric push rod is fixed to the bottom of the sealing cover.

[0010] In a preferred embodiment, a conical block is fixed inside the water cavity, and the conical block is located inside multiple nozzles. The conical block enables the high-pressure water flow to be dispersed quickly.

[0011] In a preferred embodiment, the protective cover has connecting grooves on both sides of its top. The bottom end of the piston rod and the bottom end of the guide rod of the electric push rod are fixed with connecting plates that are adapted to the connecting grooves. The connecting plates are located in the connecting grooves and are detachably connected to the protective cover by bolts. By using the connecting plates and connecting grooves to connect the electric push rod and the guide rod to the protective cover, it is easy to disassemble and maintain them later.

[0012] In a preferred embodiment, a second rubber sealing ring is provided between each jet hole and each nozzle to fill the gap between them. The second rubber sealing ring can improve the sealing between the jet hole and the nozzle, thereby reducing the risk of material flowing into the jet hole.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model provides a protective cover on the outer wall of the shell-breaking head, which can protect the jet hole from accidental injury to workers by the jet. The protective cover can also be automatically raised and lowered by an electric push rod, making it easy to adjust the height and use quickly. In addition, when the shell-breaking head is removed, sealing the jet hole with the protective cover can reduce the clogging of the nozzle by the material.

[0015] 2. The guide rod moves up and down in the limiting hole within the limiting block, which improves the stability of the protective cover's lifting. Both the electric push rod and the guide rod are connected to the connecting groove on the protective cover via a connecting plate, which facilitates disassembly and maintenance later.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Refer to the instruction manual appendix Figures 1-5 This utility model provides a water jet shell-breaking device, including a shell-breaking head 1, a water cavity 2 inside the shell-breaking head 1, and multiple jet holes 3 arranged in a ring array on the outer wall of the shell-breaking head 1. Each jet hole 3 is connected to the interior of the water cavity 2, and a nozzle 4 is fixedly installed inside each jet hole 3. One end of the nozzle 4 passes through the shell-breaking head 1 and is connected to the interior of the water cavity 2. A water supply pipe 5 is fixedly installed on the top of the shell-breaking head 1, and a protective cover 6 is fitted on the outer wall of the shell-breaking head 1, with the protective cover 6 covering the outside of the water supply pipe 5. An electric push rod 7 and a guide rod 8 are respectively provided on both sides of the top of the protective cover 6.

[0024] Among them, the electric push rod 7 is an electromechanical integrated device that converts the rotational motion of the motor into linear reciprocating motion. The electric push rod 7 drives the gearbox through the motor, which in turn drives the lead screw and nut pair to convert the rotational motion into linear motion.

[0025] A conical block 15 is fixedly installed inside the water cavity 2. The conical block 15 is located inside the multiple nozzles 4. The conical block 15 can disperse the high-pressure water flow. A second rubber sealing ring 18 is provided between each jet hole 3 and each nozzle 4 to fill the gap between them. The second rubber sealing ring 18 can improve the sealing between the jet hole 3 and the nozzle 4, thereby reducing the risk of material flowing into the jet hole 3.

[0026] In actual use, the staff first connects the water pipe 5 to the water pump, then puts the shell-breaking head 1 into the material. Subsequently, the electric push rod 7 inside the sealing cover 9 drives the protective cover 6 to move upward. After the protective cover 6 slowly moves away from the outside of the multiple nozzles 4, the water pump delivers high-pressure water to the water chamber 2 of the shell-breaking head 1. The high-pressure water is sprayed out through the multiple nozzles 4 to break the shell of the material. After the shell-breaking process is completed, the electric push rod 7 drives the protective cover 6 to move downward, and the protective cover 6 reseals the jet hole 3. At this time, the power of the water pump can be reduced so that the nozzles 4 can continue to spray water, thereby reducing the risk of the nozzles 4 being blocked to a certain extent.

[0027] Next, a limiting block 12 is fixedly embedded on the side of the water pipe 5 away from the sealing cover 9. The bottom of the limiting block 12 has a limiting hole 13 that matches the guide rod 8. The top of the guide rod 8 passes through the limiting hole 13 and extends above the limiting block 12. When the electric push rod 7 drives the protective cover 6 to move up and down, the guide rod 8 rises and falls in the limiting hole 13 in the limiting block 12, thereby improving the stability of the lifting of the protective cover 6.

[0028] Refer to the instruction manual appendix Figures 1-3 A sealing cover 9 is fixedly embedded on one side of the water supply pipe 5. The sealing cover 9 is sleeved on the outside of the electric push rod 7. A through hole 10 is opened at the bottom of the sealing cover 9. The piston rod of the electric push rod 7 passes through the through hole 10. A first rubber sealing ring 11 is provided between the piston rod of the electric push rod 7 and the through hole 10 to fill the gap between the two. A sealing cover 14 is detachably connected to the top of the sealing cover 9. The top of the electric push rod 7 is fixed to the bottom of the sealing cover 14.

[0029] The electric push rod 7 is enclosed by the sealing cover 9 and the sealing cap 14, and a first rubber sealing ring 11 is set between the piston rod of the electric push rod 7 and the through hole 10. This can improve the sealing performance of the sealing cover 9 and reduce the risk of material contamination of the electric push rod 7 to a certain extent.

[0030] like Figure 2 and Figure 3As shown, the protective cover 6 has connecting grooves 16 on both sides of its top. The bottom end of the piston rod of the electric push rod 7 and the bottom end of the guide rod 8 are both fixed with connecting plates 17 that are adapted to the connecting grooves 16. The connecting plates 17 are located in the connecting grooves 16 and are detachably connected to the protective cover 6 by bolts. By using the connecting plates 17 and the connecting grooves 16 to cooperate, the electric push rod 7 and the guide rod 8 are connected to the protective cover 6, which facilitates disassembly and maintenance in the future.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
