Steam type drying tank

Abstract

This invention discloses a steam drying tank, relating to the field of steam drying tanks, comprising a tank body. The tank body is characterized by having three steam-heating evaporator bodies arranged in a triangular pattern within its inner cavity. A sealing door is rotatably connected to the lower side of the tank body. This steam drying tank, through the setting of a limiting mechanism, effectively overcomes the defects of traditional steam drying tanks that rely on bolts, pressure plates, or simple clips for fixation, which can easily lead to loosening or displacement of the steam-heating evaporator bodies under continuous impact from high-temperature, high-pressure steam and repeated disassembly and assembly. During installation, initial alignment is achieved first using the cooperation of a crossbar and a groove. Then, the compressed L-shaped connecting rod is released. Under the spring's rebound force and the buffering effect of the damper body, the locking block automatically embeds into the locking groove, achieving fast, reliable, and buffered self-locking fixation, ensuring stable installation of the steam-heating evaporator bodies within the limited space of the tank body.

Description

Technical Field

[0001] This invention relates to steam drying tank technology, and more specifically to a steam drying tank. Background Technology

[0002] As a key piece of equipment for efficient dehydration of materials in the chemical, pharmaceutical and food processing fields, the installation stability and thermal circulation reliability of multiple sets of steam-heated evaporators inside the steam drying tank directly determine the drying efficiency, operational safety and maintenance convenience of the whole machine. In practical applications, ensuring that multiple steam-heated evaporators can be quickly positioned and reliably limited in the narrow space of the tank and that the connecting pipelines are kept sealed is the core prerequisite for ensuring the long-term stable operation of the equipment.

[0003] Existing steam-type drying tanks typically use bolts, clamps, or simple clips to secure the internal evaporators. However, this method reveals significant drawbacks when faced with repeated impacts from high-temperature, high-pressure steam inside the tank and frequent disassembly and maintenance. Due to the lack of an integrated limiting mechanism with buffer reset and self-locking functions, operators cannot simultaneously and accurately align and securely lock the evaporators within a limited space. This can easily lead to slight displacement or loosening of the evaporators during operation, resulting in failure of the connecting pipes between adjacent evaporators and steam leakage. This not only severely reduces thermal efficiency but may also pose safety hazards due to the leakage of high-temperature steam.

[0004] Therefore, the applicant proposes a steam-type drying tank to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a steam drying tank to solve the problem that in existing steam drying tanks, the steam heating evaporator body is mostly fixed with bolts, pressure plates or simple buckles. Under repeated impacts from high temperature and high pressure steam and frequent disassembly and assembly, the lack of a limiting mechanism with buffer reset and self-locking functions makes it easy for loosening and displacement to occur, resulting in failure of the connecting pipe connection, steam leakage, affecting thermal efficiency and bringing safety risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steam drying tank, comprising a tank body, wherein the inner cavity of the tank body is provided with three steam heating evaporator bodies, the three steam heating evaporator bodies are distributed in a triangular shape in the inner cavity of the tank body, a sealing door is rotatably connected to the lower part of one side of the tank body, and a connecting pipe is provided on both sides of the tank body respectively, one end of the connecting pipe passing through the side wall of the tank body and fixedly connected to the input end of the corresponding steam heating evaporator body, and two adjacent steam heating evaporator bodies are connected by a connecting pipe;

[0007] Two limiting mechanisms are provided on one side of the steam heating evaporator body. The limiting mechanism includes two retaining frames and a track plate. One side of the retaining frame has a retaining groove adapted to the steam heating evaporator body. The inner wall of one side of the retaining groove abuts against the corresponding side of the steam heating evaporator body. One side of the track plate is fixedly connected to the inner wall of the tank. Two mounting boxes are slidably connected to one side of the track plate. One side of the mounting box has a sliding groove. The inner cavity of the mounting box is provided with two L-shaped connecting rods. One side of the L-shaped connecting rod is fixedly connected to a damper body. One end of the damper body is fixedly connected to the inner wall of the corresponding mounting box. The outer ring of the damper body is fitted with a spring. One end of the L-shaped connecting rod passes through the inner cavity of the corresponding sliding groove and is fixedly connected to a locking block. Locking grooves adapted to the locking blocks are respectively provided on both sides of the retaining frame.

[0008] Two of the steam-heated evaporator bodies have two matching slots on one side of their outer wall. The other steam-heated evaporator body has two docking mechanisms on both sides. Each docking mechanism includes a straight rod, one end of which is inserted into the inner cavity of the corresponding matching slot.

[0009] Furthermore, a mounting groove is provided on one side of the straight rod, and short rods are rotatably connected to both sides of the inner cavity of the mounting groove. Matching rods are fixedly connected to both sides of the straight rod, and a locking groove is provided on one side of the upper surface of the matching rod. One end of the short rod is engaged with the inner cavity of the corresponding locking groove, and the inner wall of one side of the matching rod abuts against one side of the corresponding steam heating evaporator body.

[0010] Furthermore, inner grooves are respectively provided on both sides of the short rod, and a force-bearing block is slidably connected to the inner cavity of the inner groove.

[0011] Furthermore, a number of elastic dampers are fixedly connected to one side of the inner wall of the inner groove, and one end of the elastic damper is fixedly connected to one side of the corresponding force-bearing block.

[0012] Furthermore, the side of the force-bearing block away from the corresponding elastic damper abuts against the inner wall of the corresponding engagement groove.

[0013] Furthermore, the two sides of the short rod are rotatably connected to the inner wall of the corresponding mounting groove via a rotating shaft.

[0014] Furthermore, one end of the locking block is engaged with the inner cavity of the corresponding locking groove, two crossbars are fixedly connected to one side of the outer wall of the mounting box, a groove is provided on one side of the card frame, and one end of the crossbar is inserted into the inner cavity of the corresponding groove.

[0015] Furthermore, one end of the spring is fixedly connected to the inner wall of the corresponding mounting box, and the other end of the spring is fixedly connected to one side of the corresponding L-shaped connecting rod.

[0016] Furthermore, a slider is fixedly connected to one side of the mounting box, and one end of the slider is slidably connected to the inner cavity of the corresponding track plate.

[0017] Furthermore, the inner cavity of the connecting pipe is connected to the inner cavity of the corresponding steam-heated evaporator body.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] By setting up a limiting mechanism, the defects of traditional steam drying tanks, which rely on bolts, pressure plates, or simple clips for fixation, are effectively overcome. These defects cause the steam heating evaporator body to loosen or shift under continuous impact from high-temperature and high-pressure steam and repeated disassembly and assembly. During installation, the crossbar and groove are used to complete the initial alignment. Then, the compressed L-shaped connecting rod is released. Under the spring rebound force and the buffering effect of the damper body, the locking block automatically embeds into the locking groove, achieving fast, reliable, and buffered self-locking fixation, ensuring that the steam heating evaporator body is stably installed in the limited space of the tank.

[0020] The docking mechanism enables a quick and reliable connection between the central steam-heated evaporator body and the steam-heated evaporator bodies on both sides. After the straight rod is inserted into the fitting slot, a pressing-rotating-releasing operation causes the force-bearing block to automatically press against the inner wall of the locking slot under the action of the elastic damper, forming a rigid locking structure. This design not only effectively prevents loosening between multiple units due to thermal expansion and contraction or vibration, but also ensures that the connecting pipe and the docking pipe always maintain a sealed connection, eliminating the risk of high-temperature and high-pressure steam leakage. At the same time, it improves assembly efficiency and maintenance convenience, and ensures the stability and safety of the entire machine's thermal circulation system. Attached Figure Description

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] As attached Figure 1 To be continued Figure 10 As shown:

[0036] Example 1:

[0037] This invention provides a steam drying tank, including a tank body 1. The inner cavity of the tank body 1 is provided with three steam heating evaporator bodies 3, which are arranged in a triangular shape in the inner cavity of the tank body 1. A sealing door 2 is rotatably connected to the lower part of one side of the tank body 1. A connecting pipe 6 is provided on both sides of the tank body 1. One end of the connecting pipe 6 passes through the side wall of the tank body 1 and is fixedly connected to the input end of the corresponding steam heating evaporator body 3. Two adjacent steam heating evaporator bodies 3 are connected by a connecting pipe 7.

[0038] Two limiting mechanisms 4 are provided on one side of the steam heating evaporator body 3. The limiting mechanism 4 includes two retaining frames 401 and a track plate 402. One side of the retaining frame 401 has a retaining groove 403 adapted to the steam heating evaporator body 3. The inner wall of one side of the retaining groove 403 abuts against the corresponding side of the steam heating evaporator body 3. One side of the track plate 402 is fixedly connected to the inner wall of the tank 1. Two mounting boxes 407 are slidably connected to one side of the track plate 402. One side of the mounting box 407 has a sliding through groove 4. 08, and the inner cavity of the mounting box 407 is provided with two L-shaped connecting rods 409. One side of the L-shaped connecting rod 409 is fixedly connected to the damper body 411, and one end of the damper body 411 is fixedly connected to the inner wall of the corresponding mounting box 407. The outer ring of the damper body 411 is fitted with a spring 412. One end of the L-shaped connecting rod 409 passes through the inner cavity of the corresponding sliding groove 408 and is fixedly connected to a locking block 410. The two sides of the frame 401 are respectively provided with locking grooves 405 that are adapted to the locking block 410.

[0039] Two of the two steam-heated evaporator bodies 3 have two matching slots 8 on one side of their outer walls. The other steam-heated evaporator body 3 has two docking mechanisms 5 on both sides. The docking mechanism 5 includes a straight rod 501, one end of which is inserted into the inner cavity of the corresponding matching slot 8.

[0040] A mounting groove 502 is provided on one side of the straight rod 501. Short rods 505 are rotatably connected to both sides of the inner cavity of the mounting groove 502. A mating rod 503 is fixedly connected to both sides of the straight rod 501. A locking groove 504 is provided on one side of the upper surface of the mating rod 503. One end of the short rod 505 is locked into the inner cavity of the corresponding locking groove 504. The inner wall of one side of the mating rod 503 abuts against one side of the corresponding steam heating evaporator body 3.

[0041] Working principle: When installing the drying tank, the operator first fixes the track plate 402 to the corresponding position on the inner wall of the tank body 1. Then, the steam heating evaporator body 3, equipped with the docking mechanism 5, is horizontally pushed into the depth of the inner cavity of the tank body 1 from the sealing door 2 and positioned. The operator then places the clamping frame 401 on the outer periphery of the steam heating evaporator body 3 from the outside, so that the inner wall of one side of the clamping groove 403 abuts against the outer wall of the steam heating evaporator body 3. Then, the operator simultaneously pulls the two L-shaped connecting rods 409 inward with both hands. The L-shaped connecting rods 409 slide along the sliding groove 408 and compress the damper body 411 and the sleeve. A spring 412 located on its outer ring causes the locking block 410 to disengage from the area directly opposite the locking groove 405. In this state, the operator pushes the frame 401 forward, causing it to slide along the track plate 402 until the crossbar 413 fixed to the outer wall of the mounting box 407 is fully inserted into the inner cavity of the groove 404 opened on the side wall of the frame 401, and the front end face of the frame 401 abuts against the side wall of the mounting box 407. At this time, the operator releases the L-shaped connecting rod 409. Under the elastic force of the spring 412 and the buffering and restoring action of the damper body 411, the locking block 410 automatically slides into the inner cavity of the corresponding locking groove 405 to form a locking engagement, completing the middle part. The steam heating evaporator body 3 is fixed in place; then, the operator pushes the two steam heating evaporator bodies 3 with matching slots 8 into the tank 1 from the left and right sides respectively, so that the matching slots 8 are aligned with the straight rods 501 on both sides of the middle steam heating evaporator body 3 and horizontally inserted to complete the initial mechanical connection; then, the aforementioned limiting operation is repeated to assemble and install the corresponding clip frame 401 and the track plate 402 to achieve stable limiting of the steam heating evaporator bodies 3 on both sides; after all the limiting mechanisms 4 are installed, the operator presses the force blocks 508 on both sides of the two short rods 505 on the straight rod 501 inward. Pressing down causes the force-bearing block 508 to retract into the inner cavity of the inner groove 506. Then, rotating the short rod 505 causes one end of it to fall into the inner cavity of the engagement groove 504 on the upper surface of the mating rod 503. After releasing the hand, the elastic damper 507 pushes the force-bearing block 508 to reset, so that its outer side abuts against the inner wall of the engagement groove 504, forming a tight connection to prevent loosening. After installation, steam enters the inner cavity of any steam heating evaporator body 3 through the connecting pipe 6 on one side, flows to the other units through the connecting pipe 7 between adjacent steam heating evaporator bodies 3, and finally exits to the external heat recovery device through the connecting pipe 6 on the other side, completing the heat source cycle.

[0042] This solution, through the configuration of the frame 401, track plate 402, mounting box 407, L-shaped connecting rod 409, damper body 411, spring 412, and locking block 410, solves the problem of easy loosening and displacement of the steam heating evaporator body 3 under repeated impacts of high-temperature and high-pressure steam and frequent disassembly and assembly conditions caused by the use of bolt pressure plates or simple buckles for fixing in existing steam drying tanks. During the installation process, the crossbar 413 is inserted into the groove 404 to achieve pre-positioning, and then the locking block 410 is automatically driven to embed into the locking groove 405 by the synergistic action of the spring 412 and the damper body 411, forming a self-locking limit with buffering and reset capabilities. This ensures that the steam heating evaporator body 3 is quickly, accurately, and firmly fixed in the narrow space of the tank 1, effectively preventing the failure of the connecting pipe 7 and steam leakage due to slight displacement during operation.

[0043] Example 2:

[0044] This embodiment is basically the same as the previous embodiment, except that an inner groove 506 is provided on both sides of the short rod 505, and a force-bearing block 508 is slidably connected to the inner cavity of the inner groove 506.

[0045] Several elastic dampers 507 are fixedly connected to one side of the inner wall of the inner groove 506, and one end of the elastic damper 507 is fixedly connected to one side of the corresponding force block 508.

[0046] The side of the force-bearing block 508 away from the corresponding elastic damper 507 abuts against the inner wall of the corresponding engagement groove 504.

[0047] The two sides of the short rod 505 are rotatably connected to the inner wall of the corresponding mounting groove 502 via a rotating shaft.

[0048] One end of the locking block 410 is engaged with the inner cavity of the corresponding locking groove 405. Two crossbars 413 are fixedly connected to one side of the outer wall of the mounting box 407. A groove 404 is provided on one side of the frame 401. One end of the crossbar 413 is inserted into the inner cavity of the corresponding groove 404.

[0049] Working principle: An installation groove 502 is opened on one side of the straight rod 501. Short rods 505 are rotatably connected to both sides of the inner cavity of the installation groove 502. Matching rods 503 are fixedly connected to both sides of the straight rod 501. A locking groove 504 is opened on one side of the upper surface of the matching rod 503. One end of the short rod 505 is locked into the inner cavity of the locking groove 504. The inner wall of one side of the matching rod 503 abuts against one side of the corresponding steam heating evaporator body 3. After the straight rod 501 is inserted into the adapter through groove 8, the short rod 505 is rotated so that its end is embedded into the locking groove 504, thereby rigidly connecting the adjacent steam heating evaporator bodies 3. This achieves the effect of preventing the docking part from loosening due to vibration or thermal deformation and ensuring reliable sealing of the steam passage. An inner groove 506 is provided, and a force-bearing block 508 is slidably connected to the inner cavity of the inner groove 506. After the short rod 505 is rotated to the engaging position, the force-bearing block 508 extends outward under the action of the elastic element and contacts the inner wall of the engaging groove 504, thereby enhancing the locking force and improving the impact resistance of the connection structure. Several elastic dampers 507 are fixedly connected to one side of the inner wall of the inner groove 506. One end of the elastic damper 507 is fixedly connected to the corresponding side of the force-bearing block 508. When the force-bearing block 508 is pressed, the elastic damper 507 is compressed. After being released, the elastic damper 507 pushes the force-bearing block 508 to reset and press against the inner wall of the engaging groove 504, thereby achieving the effects of automatic locking, preventing accidental disengagement, and absorbing micro-vibrations during operation.

[0050] Example 3:

[0051] This embodiment is basically the same as the previous embodiment, except that one end of the spring 412 is fixedly connected to the inner wall of the corresponding mounting box 407, and the other end of the spring 412 is fixedly connected to one side of the corresponding L-shaped connecting rod 409.

[0052] A slider 406 is fixedly connected to one side of the mounting box 407, and one end of the slider 406 is slidably connected to the inner cavity of the corresponding track plate 402.

[0053] The inner cavity of the connecting pipe 6 is connected to the inner cavity of the corresponding steam-heated evaporator body 3.

[0054] Working principle: The short rod 505 is rotatably connected to the inner wall of the corresponding mounting groove 502 on both sides via a rotating shaft, allowing the short rod 505 to rotate flexibly around the shaft. This facilitates insertion and unlocking operations in confined spaces, improving assembly convenience and maintenance efficiency. One end of the locking block 410 engages with the inner cavity of the corresponding locking groove 405. Two crossbars 413 are fixedly connected to the outer wall of one side of the mounting box 407. A groove 404 is formed on one side of the frame 401, and one end of the crossbar 413 is inserted into the inner cavity of the corresponding groove 404. Before the frame 401 is pushed into place, the crossbar 413 first inserts into the groove 404 for guidance and pre-positioning. Subsequently, the locking block 410 automatically embeds into the locking groove 405 to complete the process. Finally, the locking mechanism ensures the precise installation of the limiting mechanism 4 and prevents misalignment and jamming. The mounting box 407 is fixedly connected to a slider 406 on one side, and one end of the slider 406 is slidably connected to the inner cavity of the corresponding track plate 402. This allows the mounting box 407 to slide smoothly along the track plate 402, guiding the frame 401 to be accurately aligned. This improves the stability of the limiting mechanism 4 and reduces installation resistance and wear. The connecting pipe 6 connects the inner cavity of the corresponding steam heating evaporator body 3, allowing external steam to enter any steam heating evaporator body 3 through the connecting pipe 6 on one side, and then flow to the other units through the connecting pipe 7 before being discharged through the connecting pipe 6 on the other side. This completes the construction of a closed-loop heat circulation circuit.

[0055] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
