SUMMARY
[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a screw heating device for screw compressors. This device offers the advantages of limiting the movement of the screw compressor body during installation and enhancing positioning effectiveness. It solves the problems caused by the lack of a limiting structure inside the mounting frame, which leads to difficulties in ensuring installation accuracy, low efficiency, increased equipment wear risk, and safety hazards. Furthermore, using only a single set of positioning bolts to position the screw compressor body and mounting frame results in insufficient connection stability, uneven stress, restricted equipment freedom, and poor reliability, shortening service life and increasing safety risks.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a screw heating device for a screw compressor, comprising a screw compressor body, a mounting frame, a heating component, and a cooling component. The mounting frame is movably mounted on the left side of the screw compressor body surface, the heating component is movably mounted on the top of the mounting frame, and the cooling component is movably mounted on the rear side of the mounting frame. A positioning mechanism is provided on the front of the mounting frame, and a limiting component is provided on the inner side of the mounting frame. Several sets of movable wheels are fixedly mounted on the bottom of the screw compressor body and are located on the front and rear sides of the bottom of the screw compressor body.
[0008] In a preferred embodiment of this utility model, the positioning mechanism includes a mounting plate, a positioning plate, and a positioning component. The mounting plate is movably mounted on the front of the mounting frame and is provided in two sets. The positioning plate is fixedly mounted on the front of the mounting frame and is located on the right side of the mounting plate. The positioning component is located on the right side of the positioning plate.
[0009] In a preferred embodiment of this utility model, the positioning assembly includes a positioning sleeve, a positioning rod, a positioning block, and a return spring. The positioning sleeve is fixedly installed on the right side of the positioning plate. The positioning rod is movably installed inside the positioning sleeve, with its right end penetrating the positioning sleeve and extending to the right side of the positioning sleeve. The positioning block is movably installed inside the positioning sleeve and fixedly connected to the left end of the positioning rod. The return spring is sleeved on the surface of the positioning rod and located inside the positioning sleeve. One end of the return spring is in contact with the right side of the positioning block, and the other end of the return spring is in contact with the left side of the inner wall of the positioning sleeve.
[0010] As a preferred embodiment of the present invention, the limiting component includes a limiting groove and a limiting plate. The limiting groove is formed on the front and right sides of the screw compressor body. The limiting plate is movably installed inside the limiting groove. The outer side of the limiting plate is fixedly connected to the front and rear sides of the inner wall of the mounting frame.
[0011] As a preferred embodiment of this utility model, the mounting plate has two sets of insert plates fixedly installed on its back side, and the screw compressor body has two sets of slots on its front side. The insert plates pass through the mounting frame from front to back and are inserted into the slots.
[0012] As a preferred embodiment of this utility model, the mounting plate has a positioning groove on the right side and two sets of such grooves are provided, and the two sets of positioning grooves are inserted and engaged with the positioning block.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting an installation plate, a positioning sleeve, and a limiting groove, installs the installation plate onto the front of the installation frame and abuts it against the left side of the positioning plate. This allows the positioning groove on the right side of the installation plate to abut against the right side of the positioning plate, facilitating the positioning block's positioning of the installation plate and the positioning plate. This effectively positions the insert plate. Pulling the positioning rod to the right causes the positioning block to move synchronously, disengaging it from the positioning groove. This allows for the assembly and disassembly of the installation plate and the insert plate. The return spring then pushes the positioning block to the left, where it engages with the positioning groove to position the installation plate. Finally, the screw compressor body is pushed to the designated position. When installing the screw compressor inside the frame, the limiting groove and the limiting plate are in active contact. The limiting groove and the limiting plate cooperate to limit the movement of the screw compressor body, thereby preventing the screw compressor body from shifting during movement, which would affect subsequent positioning and operation. This solves the problems of insufficient installation accuracy, low efficiency, increased equipment wear risk, and safety hazards caused by the lack of a limiting structure inside the mounting frame. At the same time, using only a single set of positioning bolts to position the screw compressor body and the mounting frame results in insufficient connection stability, uneven force distribution, restricted equipment freedom, and poor reliability. This also shortens the service life and increases safety hazards. This design has the advantage of limiting the movement of the screw compressor body during installation and improving the positioning effect.
[0015] 2. This utility model uses a positioning mechanism on the front of the mounting frame to install the mounting plate onto the front of the mounting frame and make it fit against the left side of the positioning plate. This allows the positioning groove on the right side of the mounting plate to fit against the right side of the positioning plate, thus facilitating the positioning block to position the mounting plate and the positioning plate, and effectively positioning the insert plate.
[0016] 3. This utility model uses a positioning component located on the right side of the positioning plate to pull the positioning rod to the right. The movement of the positioning rod causes the positioning block to move synchronously and disconnects the positioning block from the positioning groove. This allows for the disassembly and assembly of the mounting plate and the insert plate. The push force generated by the return spring pushes the positioning block to the left. The leftward movement of the positioning block engages with the positioning groove to position the mounting plate. Attached Figure Description

[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 3 As shown, the present invention provides a screw heating device for a screw compressor, comprising a screw compressor body 1, a mounting frame 2, a heating component 3, and a cooling component 4. The mounting frame 2 is movably mounted on the left side of the surface of the screw compressor body 1, the heating component 3 is movably mounted on the top of the mounting frame 2, and the cooling component 4 is movably mounted on the rear side of the mounting frame 2. A positioning mechanism 5 is provided on the front side of the mounting frame 2, and a limiting component 6 is provided on the inner side of the mounting frame 2. Several sets of movable wheels 7 are fixedly mounted on the bottom of the screw compressor body 1 and are located on the front and rear sides of the bottom of the screw compressor body 1.
[0023] refer to Figure 2 and Figure 3 The positioning mechanism 5 includes a mounting plate 51, a positioning plate 52, and a positioning component 53. The mounting plate 51 is movably mounted on the front of the mounting frame 2 and has two sets. The positioning plate 52 is fixedly mounted on the front of the mounting frame 2 and is located on the right side of the mounting plate 51. The positioning component 53 is located on the right side of the positioning plate 52.
[0024] As a technical optimization of this utility model, the positioning mechanism 5 set on the front of the mounting frame 2 installs the mounting plate 51 onto the front of the mounting frame 2 and makes it fit against the left side of the positioning plate 52. This makes the positioning groove 10 on the right side of the mounting plate 51 fit against the right side of the positioning plate 52, which facilitates the positioning block 533 to position the mounting plate 51 against the positioning plate 52, thereby effectively installing and positioning the insert plate 8.
[0025] refer to Figure 2 and Figure 3The positioning component 53 includes a positioning sleeve 531, a positioning rod 532, a positioning block 533, and a return spring 534. The positioning sleeve 531 is fixedly installed on the right side of the positioning plate 52. The positioning rod 532 is movably installed inside the positioning sleeve 531. The right end of the positioning rod 532 passes through the positioning sleeve 531 and extends to the right side of the positioning sleeve 531. The positioning block 533 is movably installed inside the positioning sleeve 531 and is fixedly connected to the left end of the positioning rod 532. The return spring 534 is sleeved on the surface of the positioning rod 532 and located inside the positioning sleeve 531. One end of the return spring 534 is in contact with the right side of the positioning block 533, and the other end of the return spring 534 is in contact with the left side of the inner wall of the positioning sleeve 531.
[0026] As a technical optimization of this utility model, the positioning component 53 located on the right side of the positioning plate 52 pulls the positioning rod 532 to the right. The movement of the positioning rod 532 drives the positioning block 533 to move synchronously and disconnects the positioning block 533 from the positioning groove 10. This allows for the disassembly and assembly of the mounting plate 51 and the insert plate 8. The thrust generated by the return spring 534 pushes the positioning block 533 to the left. The leftward movement of the positioning block 533 engages with the positioning groove 10 to position the mounting plate 51.
[0027] refer to Figure 3 The limiting component 6 includes a limiting groove 61 and a limiting plate 62. The limiting groove 61 is opened on the right side of the front and back sides of the screw compressor body 1. The limiting plate 62 is movably installed inside the limiting groove 61. The outer side of the limiting plate 62 is fixedly connected to the front and rear sides of the inner wall of the mounting frame 2.
[0028] As a technical optimization of this utility model, the limiting component 6 set on the inner wall of the mounting frame 2 pushes the screw compressor body 1 into the mounting frame 2 so that the limiting groove 61 and the limiting plate 62 are in active contact. The limiting groove 61 and the limiting plate 62 cooperate to limit the movement of the screw compressor body 1, thereby preventing the screw compressor body 1 from deviating during movement, which would affect subsequent positioning and operation.
[0029] refer to Figure 2 and Figure 3 The mounting plate 51 has two sets of insert plates 8 fixedly installed on its back. The screw compressor body 1 has two sets of slots 9 on its front. The insert plates 8 pass through the mounting frame 2 from front to back and are inserted into the slots 9.
[0030] As a technical optimization of this utility model, by setting the insert plate 8 on the back of the mounting plate 51, the insert plate 8 passes through the mounting frame 2 and is inserted into the slot 9 during the installation of the mounting plate 51. The screw compressor body 1 is positioned by the insertion plate 8 and the slot 9, thereby preventing the screw compressor body 1 from moving when it moves into the mounting frame 2 and affecting the operation of the screw compressor body 1.
[0031] refer to Figure 2 Figure 3 Figure 2 The mounting plate 51 has a positioning groove 10 on the right side, and there are two sets of the two sets of positioning grooves 10, which are inserted and cooperate with the positioning block 533.
[0032] As a technical optimization of this utility model, the positioning slot 10 is set on the right side of the mounting plate 51, and the positioning block 533 is inserted into the positioning slot 10 on the left side to position the mounting plate 51, thereby avoiding the mounting plate 51 from moving forward and affecting the positioning effect of the screw compressor body 1 when the insert plate 8 is inserted into the slot 9.
[0033] The working principle and usage process of this utility model are as follows: In use, the screw compressor body 1, mounting frame 2, heating structure, and cooling component 4 are existing technologies. The screw compressor body 1, mounting frame 2, heating component 3, and cooling component 4 have the same structure and working principle as those in the prior art document (Announcement No.: CN222223579U), and will not be repeated here. When the screw compressor body 1 is pushed into the mounting frame 2, the limiting groove 61 and the limiting plate 62 are in active contact. The limiting groove 61 and the limiting plate 62 cooperate to limit the movement of the screw compressor body 1, thereby preventing the screw compressor body 1 from shifting during movement, which would affect subsequent positioning and operation. The mounting plate 51 is installed on the front of the mounting frame 2 and is attached to the left side of the positioning plate 52, thereby making the positioning groove 10 on the right side of the mounting plate 51 attach to the right side of the positioning plate 52, thus facilitating the positioning of the block 5. 33. Positioning plate 52 is used to position mounting plate 51, thereby effectively positioning insert plate 8. Pulling positioning rod 532 to the right causes positioning block 533 to move synchronously, disengaging positioning block 533 from positioning groove 10. This allows for the disassembly and assembly of mounting plate 51 and insert plate 8. The thrust generated by return spring 534 pushes positioning block 533 to the left, engaging with positioning groove 10 to position mounting plate 51. When screw compressor body 1 is pushed into mounting frame 2, limiting groove 61 and limiting plate 62 engage. Limiting groove 61 and limiting plate 62 limit the movement of screw compressor body 1, preventing displacement during movement and thus affecting subsequent positioning and operation.
[0034] In summary, this screw heating device for a screw press, by setting up an mounting plate 51, a positioning sleeve 531, and a limiting groove 61, allows the mounting plate 51 to be installed on the front of the mounting frame 2 and to be attached to the left side of the positioning plate 52. This causes the positioning groove 10 on the right side of the mounting plate 51 to be attached to the right side of the positioning plate 52, facilitating the positioning block 533 to position the mounting plate 51 and the positioning plate 52. This effectively positions the insert plate 8. Pulling the positioning rod 532 to the right causes the positioning block 533 to move synchronously, disengaging it from the positioning groove 10. This allows for the disassembly and assembly of the mounting plate 51 and the insert plate 8. The thrust generated by the return spring 534 pushes the positioning block 533 to the left, thus facilitating the installation. Positioning block 533 moves to the left and engages with positioning groove 10 to position mounting plate 51. When screw compressor body 1 is pushed into mounting frame 2, limiting groove 61 and limiting plate 62 engage. Limiting groove 61 and limiting plate 62 cooperate to limit the movement of screw compressor body 1, thereby preventing screw compressor body 1 from shifting during movement, which would affect subsequent positioning and operation. This solves the problems of insufficient installation accuracy, low efficiency, increased equipment wear risk, and safety hazards caused by the lack of a limiting structure inside the mounting frame. At the same time, positioning the screw compressor body and mounting frame with only a single set of positioning bolts will result in insufficient connection stability, uneven force, restricted equipment freedom, and poor reliability, which will shorten service life and increase safety hazards.
