Technical Field

[0001] This utility model relates to the field of waste compression technology, and in particular to a protective structure for the pressure head of a vertical compression station. Background Technology

[0002] The vertical compression head is the core component of a vertical waste compression station. Essentially, it is a heavy-duty compression block driven by hydraulic pressure. Its core function is to forcefully compress loose waste, industrial waste, and other materials vertically to reduce their volume and facilitate efficient subsequent transportation or storage. It is a key component that determines the processing efficiency, compression effect, and equipment lifespan of the compression station.

[0003] Some existing vertical waste compression stations lack protective structures on the surface of their compression heads. After prolonged use, wear and corrosion occur, requiring complete replacement or repair. Complete replacement is costly, and the repair process can easily disrupt the normal operation of the vertical waste compression station.

[0004] Therefore, a protective structure for the pressure head of a vertical compression station is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a protective structure for the pressure head of a vertical compression station, which can solve the problem that the surface of the pressure head of some existing vertical garbage compression stations does not have a protective structure. After the pressure head is worn and corroded after long-term use, it needs to be replaced or repaired as a whole. The cost of replacement is high and the repair process can easily affect the normal operation of the vertical garbage compression station.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective structure for a vertical compressor head, comprising a compressor head body and a telescopic cylinder. A protective sleeve is fitted over the surface of the compressor head body, the bottom of the compressor head body contacts the bottom of the inner wall of the protective sleeve, a plug-in mechanism is provided at the top of the compressor head body, a reinforcing block is provided at the bottom of the protective sleeve, and a connecting mechanism is provided at the top of the reinforcing block. The number of connecting mechanisms is four. The plug-in mechanism includes a double-headed cylinder, two connecting frames, and two insert plates. The bottom of the double-headed cylinder is fixedly connected to the top of the compressor head body, the telescopic end of the double-headed cylinder is fixedly connected to the connecting frame, and the bottom of the connecting frame is fixedly connected to the top of the insert plate.

[0007] Preferably, the front and rear sides of the top two sides of the protective cover are fixedly connected with connecting clips, and the surface of the insert plate is in contact with the inner wall of the connecting clip.

[0008] Preferably, the top of each of the two insert plates on opposite sides is chamfered, and the material of the connecting card and the insert plates is maraging steel.

[0009] Preferably, the protective sleeve is made of stainless steel, and the surface of the protective sleeve is coated with polytetrafluoroethylene propylene coating.

[0010] Preferably, the connecting mechanism includes a nut, a connecting hole, and a stud. The bottom of the stud is fixedly connected to the top of the reinforcing block. The connecting hole is opened at the bottom of the inner wall of the protective sleeve. The top of the stud passes through the connecting hole. The nut is threaded onto the surface of the stud.

[0011] Preferably, the nut is located inside the connecting hole, and the top of the stud is on the same plane as the bottom of the inner wall of the protective sleeve.

[0012] Preferably, the reinforcing block has four grooves inside, and a fixing block is fixedly connected to the inner wall of the groove. The surface of the fixing block has a notch.

[0013] Preferably, the reinforcing block is made of high-chromium cast iron, and a counterweight is fixedly connected to the rear side of the top of the pressure head body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application, by setting up an insertion mechanism, first moves the pressure head body into the protective sleeve, then supplies air to the double-headed cylinder through an external air source, and controls the extension of the telescopic end through an external controller. Since the bottom of the double-headed cylinder is fixed to the top of the pressure head body, and the telescopic end is fixed to the connecting frame and the connecting frame to the insert plate respectively, the extension of the telescopic end will drive the connecting frame and the insert plate to move synchronously, and finally the insert plate is inserted into the inner wall of the connecting card on the front and rear sides of the top of the protective sleeve, completing the connection between the two. The chamfered design at the top of the insert plate can reduce the difficulty of insertion and alignment, and facilitate quick cooperation. The connecting card and the insert plate are made of martensitic aging steel, which, with its high strength, high toughness and wear resistance, can withstand the impact and extrusion force when the pressure head is working, avoids the deformation and damage of the parts, and always ensures the stability and reliability of the connection, providing a basic guarantee for the protection of the pressure head body by the protective sleeve. 2. This application utilizes a connecting mechanism where a stud passes through a connecting hole at its top. A nut is then threaded onto the stud surface and tightened, thus securing the reinforcing block to the protective sleeve. The nut is located inside the connecting hole, and the top of the stud is flush with the bottom of the inner wall of the protective sleeve. This design prevents the nut and stud from protruding and interfering with the pressure head body, ensuring a good fit between the pressure head body and the protective sleeve. It also prevents waste from getting stuck in protruding parts and affecting the compression operation. Through this mechanism, the reinforcing block can be stably installed and directly contact the waste, providing wear-resistant protection. Furthermore, when the reinforcing block wears out, it can be replaced individually by disassembling the nut and stud, reducing operating costs and preventing the pressure head body repair from affecting the normal operation of the compression station.

[0017] 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.

[0018] Please see Figure 1-7 The present invention provides the following technical solution: A protective structure for a vertical compressor head includes a compressor head body 1 and a telescopic cylinder 6. A protective sleeve 2 is fitted over the surface of the compressor head body 1. The bottom of the compressor head body 1 contacts the bottom of the inner wall of the protective sleeve 2. A plug-in mechanism 4 is provided on the top of the compressor head body 1. A reinforcing block 3 is provided on the bottom of the protective sleeve 2. A connecting mechanism 7 is provided on the top of the reinforcing block 3. There are four connecting mechanisms 7. The plug-in mechanism 4 includes a double-headed cylinder 401, two connecting frames 402, and two insert plates 403. The bottom of the double-headed cylinder 401 is fixedly connected to the top of the compressor head body 1. The telescopic end of the double-headed cylinder 401 is fixedly connected to the connecting frame 402. The bottom of the connecting frame 402 is fixedly connected to the top of the insert plate 403.

[0019] In this embodiment: the protective sleeve 2 is first moved to the bottom of the pressure head body 1, and then the pressure head body 1 is lowered into the protective sleeve 2 by the telescopic cylinder 6 of the vertical compression station. The protective sleeve 2 is made of stainless steel, which has good strength and corrosion resistance. The surface is coated with polytetrafluoroethylene propylene coating, which can prevent garbage and sewage from adhering and enhance corrosion resistance. Then, the external air source is connected to the double-headed cylinder 401 of the insertion mechanism 4. The extension end of the cylinder is controlled by the external controller, which drives the connecting frame 402 and the insert plate 403 to move, so that the insert plate 403 is inserted into the connecting card 5 at the top of the protective sleeve 2, so that the protective sleeve 2 and the pressure head body 1 are stably connected. The chamfer of the insert plate 403 plays a guiding role. The connecting card 5 and the insert plate 403 are made of maraging steel, which can resist impact and extrusion. During the compression operation, the high-chromium cast iron reinforcing block 3 at the bottom of the protective sleeve 2 is wear-resistant and is connected by the stud 7. 03. Nut 701 is connected to protective sleeve 2, and nut 701 and stud 703 do not interfere with the movement of the pressure head body 1. The groove 8 of reinforcing block 3 and the fixing block 9 with notch 10 facilitate the connection of the connecting rope of external hoisting equipment for hoisting. The counterweight block 11 on the rear side of the top of the pressure head body 1 balances the weight and ensures the stable operation of the pressure head body 1. After the reinforcing block 3 is worn, only the reinforcing block 3 needs to be replaced, which reduces the cost of use. Directly replacing the reinforcing block 3 can avoid the problem of repairing the worn pressure head body 1 and affecting the normal operation of the vertical compression station. This solves the problem that the surface of the pressure head of some existing garbage vertical compression stations does not have a protective structure. After the pressure head is worn and corroded for a long time, it needs to be replaced or repaired as a whole. The cost of overall replacement is high, and the repair process can easily affect the normal operation of the garbage vertical compression station.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, connecting clips 5 are fixedly connected to the front and rear sides of the top two sides of the protective sleeve 2, and the surface of the insert plate 403 is in contact with the inner wall of the connecting clip 5.

[0021] Specifically, such as Figure 1 , Figure 3 and Figure 7 As shown, the top of the two insert plates 403 on opposite sides is chamfered, and the materials of the connecting card 5 and the insert plate 403 are both maraging steel.

[0022] Specifically, such as Figure 1 As shown, the protective sleeve 2 is made of stainless steel, and the surface of the protective sleeve 2 is coated with polytetrafluoroethylene propylene coating.

[0023] In this embodiment: the connecting clips 5 on the front and rear sides of the top of the protective sleeve 2 cooperate with the insert plate 403 to achieve a stable connection between the protective sleeve 2 and the pressure head body 1, ensuring the reliability of the protective sleeve 2 in protecting the pressure head body 1. The chamfer on the top of the insert plate 403 reduces the difficulty of aligning the insert plate 403 and the connecting clip 5, making it easier to quickly complete the insertion and connection. The connecting clip 5 and the insert plate 403 are made of maraging steel, which, with its high strength, high toughness and wear resistance, can withstand the impact and extrusion force during the operation of the pressure head, avoid deformation and damage, and extend the service life of the insertion parts. The protective sleeve 2 is made of stainless steel, which has good strength and corrosion resistance, providing basic protection for the pressure head body 1. The polytetrafluoroethylene propylene coating on the surface has extremely low surface energy, which can prevent the adhesion of garbage and sewage, reduce the difficulty of cleaning, and has strong chemical inertness, further enhancing the corrosion resistance of the protective sleeve 2 and extending the service life of the protective sleeve 2.

[0024] Specifically, such as Figure 5 As shown, the connecting mechanism 7 includes a nut 701, a connecting hole 702, and a stud 703. The bottom of the stud 703 is fixedly connected to the top of the reinforcing block 3. The connecting hole 702 is opened at the bottom of the inner wall of the protective sleeve 2. The top of the stud 703 passes through the connecting hole 702. The nut 701 is threaded onto the surface of the stud 703.

[0025] Specifically, such as Figure 4 and Figure 5 As shown, the nut 701 is located inside the connecting hole 702, and the top of the stud 703 is on the same plane as the bottom of the inner wall of the protective sleeve 2.

[0026] In this embodiment: In the connecting mechanism 7, the stud 703 penetrates the connecting hole 702 of the protective sleeve 2, and together with the nut 701, firmly fixes the reinforcing block 3 to the bottom of the protective sleeve 2, ensuring the stability of the connection between the reinforcing block 3 and the protective sleeve 2, and providing a guarantee for the reinforcing block 3 to play a wear-resistant role. The nut 701 is located inside the connecting hole 702, and the top of the stud 703 is flush with the bottom of the inner wall of the protective sleeve 2, which can prevent the nut 701 and the stud 703 from protruding and interfering with the pressure head body 1, and ensure the fit between the pressure head body 1 and the protective sleeve 2.

[0027] Specifically, such as Figure 6 As shown, the interior of the reinforcing block 3 has four grooves 8. The inner wall of the groove 8 is fixedly connected to a fixing block 9, and the surface of the fixing block 9 has a notch 10.

[0028] Specifically, such as Figure 1 As shown, the reinforcing block 3 is made of high-chromium cast iron, and a counterweight block 11 is fixedly connected to the rear side of the top of the pressure head body 1.

[0029] In this embodiment: the fixing block 9 with notch 10 in the groove 8 facilitates the connection of the connecting rope of the external hoisting equipment, and facilitates the installation and replacement of the reinforcing block 3. The reinforcing block 3 is made of high chromium cast iron, which has high carbide hardness and excellent wear resistance. It can resist the wear and puncture of hard impurities in the garbage, and prevent the garbage from directly contacting the protective sleeve 2, thus affecting the service life of the protective sleeve 2. The counterweight block 11 on the rear side of the top of the pressure head body 1 can balance the weight of the front and rear sides of the pressure head body 1, and prevent the pressure head body 1 from tilting or jamming due to the shift of the center of gravity, thus ensuring that the compression operation of the pressure head body 1 is smooth and accurate.

[0030] Working Principle: First, the protective sleeve 2 is moved to the bottom of the pressure head body 1. The telescopic cylinder 6 of the vertical compression station controls the pressure head body 1 to descend into the interior of the protective sleeve 2, ensuring close contact between the bottom of the pressure head body 1 and the bottom of the inner wall of the protective sleeve 2. The protective sleeve 2 is made of stainless steel, which possesses good strength and corrosion resistance, providing basic protective support for the pressure head body 1. Simultaneously, the surface of the protective sleeve 2 is coated with polytetrafluoroethylene (PTFE) paint. PTFE has extremely low surface energy, effectively preventing the adhesion of garbage, sewage, and viscous substances to the surface of the protective sleeve 2, reducing subsequent cleaning difficulties. Furthermore, its strong chemical inertness further enhances the corrosion resistance of the protective sleeve 2, extending its service life. After the initial cleaning of the protective sleeve 2... After the sleeve is installed, it is connected to the double-headed cylinder 401 in the insertion mechanism 4 via an external air source. The extension end of the double-headed cylinder 401 is controlled by an external controller. Since the bottom of the double-headed cylinder 401 is fixedly connected to the top of the pressure head body 1, and its extension end is fixedly connected to the connecting frame 402, and the bottom of the connecting frame 402 is fixedly connected to the top of the insert plate 403, the extension end of the double-headed cylinder 401 will drive the connecting frame 402 and the insert plate 403 to move synchronously. The front and rear sides of the top of the protective sleeve 2 are fixedly connected to the connecting clips 5. Finally, the surface of the insert plate 403 will insert into the inner wall of the connecting clip 5 and contact it, thereby firmly connecting the protective sleeve 2 and the pressure head body 1 together. The top of the two insert plates 403 on opposite sides is chamfered. The chamfered design guides the insertion of the insert plate 403 into the connecting card 5, reducing the difficulty of alignment between the insert plate 403 and the connecting card 5, and facilitating quick connection. Both the connecting card 5 and the insert plate 403 are made of maraging steel, which possesses high strength, high toughness, and excellent wear resistance. This allows them to withstand the impact and extrusion forces generated during the operation of the pressure head, preventing deformation or damage to the connecting card 5 and the insert plate 403 due to excessive force, thus ensuring the stability and reliability of the connection mechanism 4. During waste compression, a reinforcing block 3 is installed at the bottom of the protective sleeve 2. This reinforcing block 3 directly contacts the waste and is made of high-chromium cast iron. High-chromium cast iron contains a large amount of chromium, resulting in carbides with extremely high hardness. It possesses excellent wear resistance, effectively resisting the wear and puncture of the bottom of the protective sleeve 2 by hard impurities in the waste, extending the overall service life of the protective structure. The top of the stud 703 passes through the connecting hole 702, and the nut 701 is threaded onto the surface of the stud 703. By tightening the nut 701, the reinforcing block 3 can be firmly fixed to the bottom of the protective sleeve 2. The nut 701 is located inside the connecting hole 702, and the top of the stud 703 is flush with the bottom of the inner wall of the protective sleeve 2. This design prevents the nut 701 and stud 703 from protruding from the inner wall of the protective sleeve 2 and interfering with the pressure head body 1, ensuring a good fit between the pressure head body 1 and the protective sleeve 2. In addition, the reinforcing block 3 has four grooves 8 inside, and the inner wall of each groove 8 is fixedly connected to a fixing block 9.The surface of the fixing block 9 has a notch 10. The setting of the groove 8 and the fixing block 9 allows for easy connection of the external hoisting equipment's connecting rope to the notch 10 inside the fixing block 9, facilitating the hoisting of the reinforcing block 3. In addition, a counterweight 11 is fixedly connected to the rear side of the top of the pressure head body 1. Due to the uneven weight distribution caused by the installation of components such as the plug-in mechanism 4 on the front side of the pressure head body 1, the counterweight 11 can balance the weight of the front and rear sides of the pressure head body 1, keeping the pressure head stable during up-and-down movement and garbage compression. This avoids problems such as tilting and jamming due to the shift of the center of gravity, ensuring the smoothness and accuracy of the pressure head's compression operation, and thus guaranteeing the working efficiency of the entire vertical compression station. The reinforcing block 3 is worn. After damage, only the reinforcing block 3 needs to be replaced, reducing operating costs. Directly replacing the reinforcing block 3 avoids the need to repair the worn pressure head body 1, which would affect the normal operation of the vertical compression station. This solves the problem that some existing vertical garbage compression stations lack a protective structure on the surface of the pressure head, requiring overall replacement or repair after prolonged use due to wear and corrosion. Overall replacement is costly, and the repair process can easily disrupt the normal operation of the vertical garbage compression station. It should be noted that both the pressure head body 1 and the double-headed cylinder 401 are existing, published, and mature technologies. Any content not described in detail in this specification is prior art known to those skilled in the art and will not be elaborated upon here.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
