Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a sanitary pure steam cylinder. Background Art

[0002] Pharmaceutical steam is the most widely used heating medium in the pharmaceutical industry and is involved in the entire production process, including raw material production, separation and purification, and finished product preparation. When pharmaceutical companies produce sterile products, the commonly used steam is mainly industrial steam and pure steam. Industrial steam is often used for humidification of air-conditioning systems in non-critical positions, tank jacket heating, heat exchanger heating, and sterilization of non-contact product equipment; pure steam is often used for wet heat sterilization of sterilizers and other processes, such as sterilization of equipment and pipelines and air-conditioning humidification in key process positions. The qualified pure steam produced will be transported to various use points through pure steam distribution pipelines, and steam cylinders are required in the pure steam distribution system.

[0003] The utility model with authorization announcement number CN213810571U provides a carbon steel sub-cylinder with adjustable height, wherein the sub-cylinder is supported by two supporting legs, and the height adjustment of the sub-cylinder is achieved by adjusting the distance between the two supporting legs. After the adjustment, the folding assembly and the two supporting legs play a double-layer support role, making the sub-cylinder more stable.

[0004] In the above patent, when the sub-cylinder needs to be disassembled and repaired, or the installation height of the sub-cylinder needs to be adjusted, the sub-cylinder needs to be disassembled and adjusted as a whole, which takes a lot of time and reduces work efficiency. At the same time, when disassembling the sub-cylinder with a higher installation height, workers are required to move the sub-cylinder to a higher position, which consumes a lot of manpower and there is a risk of the sub-cylinder falling from a high place and being damaged. In view of this, we propose a sanitary pure steam sub-cylinder. Summary of the invention

[0005] The utility model aims to provide a sanitary pure steam cylinder to solve the problems raised in the above background technology.

[0006] To achieve the above object, one of the objects of the present utility model is to provide a hygienic pure steam manifold, which includes a manifold body. A support plate is provided on the lower surface of the manifold body. Two clamping plates are symmetrically provided at the top of the support plate. The two clamping plates are respectively located on both sides of the manifold body. A clamping mechanism is provided at the bottom of the two clamping plates. The clamping mechanism is used to drive the two clamping plates to horizontally move synchronously away from or towards the manifold body. A base is provided below the support plate. A height adjustment mechanism is provided on the base. When the clamping mechanism drives the two clamping plates to move to the positions where they are in contact with both sides of the manifold body respectively, the height adjustment mechanism is used to drive the support plate to move vertically. When the clamping mechanism drives the two clamping plates to move synchronously away from the manifold body, the support plate descends to the lowest position.

[0007] As a further improvement of this technical solution, the height adjustment mechanism includes two lead screws symmetrically and rotatably connected to the upper surface of the base. Two outer chutes are symmetrically opened at the top of the support plate. Two outer sliders are symmetrically provided in the outer chutes. The outer sliders slide inside the outer chutes. The outer sliders are fixedly connected to the lower surface of the clamping plates. The upper ends of the lead screws penetrate through the bottom of the support plate and extend into the corresponding outer chutes, and the upper ends of the lead screws are located between the two outer sliders in the same outer chute. A half nut is fixedly connected to one side of the outer slider close to the lead screw. When the two clamping plates respectively move to the positions where they are in contact with both sides of the manifold body, the two half nuts on both sides of the lead screw are combined into a complete nut, and the combined nut is threadedly connected to the lead screw.

[0008] As a further improvement of this technical solution, two support plates are symmetrically and fixedly connected to the upper surface of the base. The support plates are of L-shaped structure. The vertical sections of the two support plates are respectively in contact with both sides of the support plate. When the lower surface of the support plate is in contact with the upper surface of the horizontal section of the support plate, the support plate descends to the lowest position.

[0009] As a further improvement of this technical solution, a worm gear is fixedly connected to the side wall of the lead screw. A worm is rotatably connected to the upper surface of the base. The two worm gears are both engaged with the worm. One end of the worm penetrates through the side wall of one of the support plates.

[0010] As a further improvement of this technical solution, an inner slider is fixedly connected to the bottom of the clamping plate. An inner chute is opened at the top of the support plate. The inner slider is slidably arranged inside the inner chute. The clamping mechanism includes a positioning block fixedly connected to a position close to the bottom inside the inner chute. A threaded rod is rotatably connected to the side wall of the positioning block. Threaded strips are provided at both ends of the threaded rod. The inner slider is threadedly connected to the threaded strips. The threaded strips at both ends of the threaded rod are helical in opposite directions.

[0011] As a further improvement of the technical solution, a support mechanism is provided on the outer slider. The support mechanism includes an extension plate provided on one side of the outer chute. One side of the extension plate penetrates through the outer chute and is fixed to the side wall of the outer slider. A baffle is fixedly connected to the bottom position of the extension plate close to the outer slider. A rotating plate is provided below the baffle. One end of the rotating plate is hinged to the extension plate, and a spring is fixedly connected between the lower surface of the rotating plate and the side wall of the extension plate. Four vertical plates are fixedly connected to the upper surface of the base. A plurality of tooth grooves are vertically arranged in an array on the side of the vertical plate close to the extension plate. One end of the rotating plate is located inside one of the tooth grooves. When the rotating plate is in a horizontal state, the lower surface of the rotating plate contacts the inner wall of the tooth groove, and the baffle blocks the upper surface of the rotating plate.

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

[0013] When clamping and fixing the steam separator body on the support plate, the installation height of the steam separator body can be adjusted, which is convenient for using the steam separator body. When disassembling, installing and overhauling the steam separator body from the support plate, the installation height of the steam separator body can automatically drop. When the worker removes the steam separator body from the support plate, there is no need to carry the steam separator body to a relatively high position, which is relatively labor-saving. At the same time, the risk of damage to the steam separator body caused by falling from a relatively high position during the handling process is eliminated, and the safety during the disassembly, installation and overhaul of the steam separator body is improved.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0031] Please refer to Figures 1 - 2 As shown, one of the purposes of this embodiment is to provide a hygienic pure steam manifold, including a manifold body 1. A support plate 2 is arranged on the lower surface of the manifold body 1. Two clamping plates 3 are symmetrically arranged at the top of the support plate 2. The two clamping plates 3 are respectively located on both sides of the manifold body 1. A clamping mechanism 5 is arranged at the bottom of the two clamping plates 3. The clamping mechanism 5 is used to drive the two clamping plates 3 to move horizontally in the direction away from or close to the manifold body 1 synchronously. An arc groove is formed on the side of the clamping plate 3 close to the manifold body 1. By driving the two clamping plates 3 to move horizontally in the direction close to the manifold body 1 synchronously through the clamping mechanism 5 until the arc grooves of the two clamping plates 3 are in contact with the side wall of the manifold body 1, the manifold body 1 can be clamped and fixed on the support plate 2. A base 4 is arranged below the support plate 2. A space is arranged between the support plate 2 and the base 4. By installing the base 4 on the installation platform of the manifold body 1, the installation of the manifold body 1 can be completed. When it is necessary to disassemble, install and repair the manifold body 1, by moving the clamping plate 3 in the direction away from the manifold body 1, it is convenient to disassemble and install the manifold body 1.

[0032] The structure of the clamping mechanism 5 is refined as follows. Refer toFigure 3 , Figure 4 and Figure 5 , a clamping plate 3 is fixedly connected to the bottom of an inner slider 33, an inner chute 22 is formed at the top of a support plate 2, the inner slider 33 is slidably disposed inside the inner chute 22, a clamping mechanism 5 includes a positioning block 51 fixedly connected to a position near the bottom inside the inner chute 22, a threaded rod 52 is rotatably connected to the side wall of the positioning block 51, both ends of the threaded rod 52 are provided with threaded strips, the inner slider 33 is threadedly connected to the threaded strips, and the threaded strips at both ends of the threaded rod 52 are spiraled in opposite directions. When the threaded rod 52 is rotated, through the threaded connection between the inner slider 33 and the threaded strips, the two inner sliders 33 horizontally move synchronously along the inner wall of the inner chute 22 in a direction close to or away from the positioning block 51. When the inner slider 33 horizontally moves, the clamping plate 3 on its top synchronously horizontally moves, so that the two clamping plates 3 can horizontally move synchronously in a direction close to the main steam distribution cylinder body 1, and the main steam distribution cylinder body 1 is clamped and fixed on the support plate 2.

[0033] When installing the main steam distribution cylinder body 1, it is necessary to adjust the installation height of the main steam distribution cylinder body 1 according to the use requirements to facilitate the operation of the operator to use the main steam distribution cylinder body 1. To facilitate the adjustment of the installation height of the main steam distribution cylinder body 1, a height adjustment mechanism 6 is provided on the base 4. The structure of the height adjustment mechanism 6 is refined as follows. Refer to Figure 6 , the height adjustment mechanism 6 includes two lead screws 61 symmetrically and rotatably connected to the upper surface of the base 4. Two outer chutes 21 are symmetrically formed at the top of the support plate 2. Two outer sliders 31 are symmetrically disposed in the outer chutes 21. The outer sliders 31 slide inside the outer chutes 21. The outer sliders 31 are fixedly connected to the lower surface of the clamping plate 3. Two outer sliders 31 are fixed to the lower side of one of the clamping plates 3, and these two outer sliders 31 are respectively disposed in the two outer chutes 21. The upper end of the lead screw 61 penetrates through the bottom of the support plate 2 and extends into the corresponding outer chute 21, and the upper end of the lead screw 61 is located between the two outer sliders 31 in the same outer chute 21. A half nut 32 is fixedly connected to the side of the outer slider 31 close to the lead screw 61.

[0034] When the two clamping plates 3 respectively move to the positions in contact with both sides of the steam distribution cylinder body 1, the two half nuts 32 located on both sides of the lead screw 61 are combined into a complete nut, and the combined nut is threadedly connected to the lead screw 61. A worm gear 62 is fixedly connected to the side wall of the lead screw 61, and a worm 63 is rotatably connected to the upper surface of the base 4. Both worm gears 62 are engaged with the worm 63. One end of the worm 63 penetrates through the side wall of one of the support plates 41. When the worm 63 is rotated, through the meshing transmission between the two worm gears 62 and the worm 63, the two worm gears 62 rotate synchronously. The worm 63 drives the corresponding lead screw 61 to rotate. Through the threaded connection between the lead screw 61 and the nut, the nut drives the outer slider 31 to vertically move along the axis of the lead screw 61. When the outer slider 31 moves, it drives the support plate 2 to move synchronously, thereby adjusting the height of the support plate 2 and adjusting the installation height of the steam distribution cylinder body 1 clamped and fixed on the support plate 2.

[0035] When the main body 1 of the steam distribution cylinder moves to a high position and disengages from the support plate 41, the supporting plate 2 can only support the weight of the main body 1 of the steam distribution cylinder by the force generated by the threaded connection between the half nut 32 and the lead screw 61. At this time, the pressure on the half nut 32 is relatively large, and there is a situation where the threads between the half nut 32 and the lead screw 61 slip, resulting in the tilting and dropping of the main body 1 of the steam distribution cylinder. To ensure the stability of the main body 1 of the steam distribution cylinder during use, a support mechanism 7 is provided on the outer slider 31. The support mechanism 7 includes an extension plate 71 provided on one side of the outer chute 21. One side of the extension plate 71 penetrates through the outer chute 21 and is fixed to the side wall of the outer slider 31. A baffle 72 is fixedly connected to the bottom position of the extension plate 71 close to the outer slider 31. A rotating plate 73 is provided below the baffle 72. The baffle 72 and the rotating plate 73 are arranged in the space between the supporting plate 2 and the base 4. One end of the rotating plate 73 is hinged to the extension plate 71. A spring 74 is fixedly connected between the lower surface of the rotating plate 73 and the side wall of the extension plate 71. The spring 74 pushes the rotating plate 73 upward to rotate. Four vertical plates 42 are fixedly connected to the upper surface of the base 4. The vertical plates 42 are arranged on one side of the extension plate 71. When the half nut 32 approaches the lead screw 61, the outer slider 31 drives the extension plate 71 and the rotating plate 73 to approach the vertical plate 42. A plurality of tooth grooves 43 are vertically arranged in an array on the side of the vertical plate 42 close to the extension plate 71. The inner wall of the tooth groove 43 has an inclined surface on the upper side and a flat surface on the lower side. One end of the rotating plate 73 is located inside one of the tooth grooves 43. When the outer slider 31, the supporting plate 2, and the main body 1 of the steam distribution cylinder move vertically upward, the outer slider 31 drives the extension plate 71, the baffle 72, the rotating plate 73, and the spring 74 to move upward synchronously. After the upward moving rotating plate 73 contacts the inclined surface of the tooth groove 43, the inclined surface of the tooth groove 43 pushes the rotating plate 73 to rotate downward, causing the spring 74 to elastically contract. When the rotating plate 73 moves out of the tooth groove 43, the spring 74 rebounds and pushes the rotating plate 73 to rotate upward, and the rotating plate 73 is rotated into the interior of a tooth groove 43 located above. At this time, one end of the rotating plate 73 is blocked by the inclined surface of another tooth groove 43, and during the upward movement of the outer slider 31, the rotating plate 73 rotates reciprocally until the main body 1 of the steam distribution cylinder moves to the predetermined installation height. At this time, the outer slider 31 no longer moves. At this time, the height of the main body 1 of the steam distribution cylinder is finely adjusted so that the rotating plate 73 remains horizontal inside one of the tooth grooves 43, that is, the main body 1 of the steam distribution cylinder moves downward. When the rotating plate 73 is in a horizontal state, the lower surface of the rotating plate 73 contacts the inner wall of the tooth groove 43, and the baffle 72 blocks the upper surface of the rotating plate 73 to prevent the rotating plate 73 from rotating upward. At this time, the rotating plate 73 is positioned on the vertical plate 42 by the blocking of the tooth groove 43 and the baffle 72. After the rotating plate 73 is positioned, the extension plate 71 prevents the outer slider 31 and the supporting plate 2 from moving downward. At this time, the blocked supporting plate 2 assists in supporting the main body 1 of the steam distribution cylinder, improving the stability of the main body 1 of the steam distribution cylinder when it moves to a high position and avoiding the situation where the half nut 32 is under excessive pressure and slips with the lead screw 61.

[0036] When the steam header body 1 needs to be disassembled, repaired and overhauled, the threaded rod 52 needs to be rotated reversely, so that the two clamping plates 3 move synchronously away from the steam header body 1, releasing the clamping and fixing of the clamping plates 3 on the steam header body 1. When the clamping plates 3 move, the two outer sliders 31 at their bottoms move synchronously. The outer sliders 31 drive the half nuts 32 fixedly connected thereto to move, separating the two half nuts 32 that form a nut. The half nuts 32 are disengaged from the lead screw 61. At the same time, the outer sliders 31 drive the extension plate 71, the baffle plate 72, the rotating plate 73 and the spring 74 to move away from the half nuts 32, moving one end of the rotating plate 73 out of the inside of the tooth groove 43, so that the rotating plate 73 loses the function of preventing the outer sliders 31 and the support plate 2 from moving downward. Furthermore, the support plate 2 descends under the action of gravity. Two support plates 41 are symmetrically and fixedly connected to the upper surface of the base 4. The support plates 41 are of an L-shaped structure. The vertical sections of the two support plates 41 are respectively in contact with both sides of the support plate 2, so that the two support plates 41 play a guiding role for the support plate 2, improving the stability of the support plate 2 during vertical movement. When the support plate 2 descends to a position in contact with the upper surface of the horizontal section of the support plate 41, the support plate 2 descends to the lowest position, thus avoiding collision between the support plate 2 and the worm 63. After the steam header body 1 follows the support plate 2 and descends to the lowest position, when the worker removes the steam header body 1 from the support plate 2, there is no need to carry the steam header body 1 to a higher position, which is more labor-saving. At the same time, the risk of the steam header body 1 falling from a higher position during transportation is eliminated, improving the safety when disassembling, repairing and overhauling the steam header body 1.
