Description

Technical Field

[0001] This utility model relates to the field of dyeing and finishing technology, specifically to a waste heat recovery device for knitting dyeing and finishing equipment. Background Technology

[0002] Dyeing and finishing is a processing method, encompassing pretreatment, dyeing, printing, finishing, washing, and more. It involves using dyeing and finishing techniques to perfectly reproduce our favorite colors and patterns on raw fabric, thus enhancing the artistic appeal of the textile. Existing dyeing and finishing equipment requires heat treatment during processing, generating considerable heat. To avoid resource waste, waste heat recovery devices are typically used to recover excess heat.

[0003] Existing waste heat recovery devices for dyeing and finishing equipment typically use pipelines to transport waste liquid containing heat and then recover the waste heat through heat exchangers. However, after a long period of operation, the pipelines used for transport are prone to sedimentation and accumulation due to the reaction with the waste liquid, requiring regular cleaning and maintenance. Traditional waste heat recovery devices are inconvenient to operate due to the fixed location of the pipelines, which affects efficiency.

[0004] Therefore, we propose a waste heat recovery device for knitting dyeing and finishing equipment to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a waste heat recovery device for knitting dyeing and finishing equipment, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A waste heat recovery device for a knitting dyeing and finishing equipment includes: an outer shell, two sets of support plates fixed on both sides of the outer shell, a rotating bracket installed between the two sets of support plates, and a first baffle and a second baffle installed on both sides of the rotating bracket.

[0010] It also includes: two sets of grooves are respectively opened on the top and one side of the outer shell, the first baffle and the second baffle are respectively installed in the two sets of grooves, and two sets of first sliders are respectively fixed on both sides of the first baffle and the second baffle. Two sets of waist-shaped slots are also opened on both sides of the grooves opened on the outer shell, allowing the first sliders fixed on both sides of the first baffle and the second baffle to move along the direction of the waist-shaped slots.

[0011] Two sets of identical grooves are also provided on the two sets of support plates fixed on both sides of the outer shell. The rotating bracket is also equipped with a second slider that matches the size of the groove on the support plate, allowing the second slider to move along the groove opening direction on the inner wall of the groove.

[0012] Furthermore, slots are provided inside the waist-shaped slots on both sides of the outer shell, and the limiting block is installed inside the waist-shaped slot through the slot.

[0013] Furthermore, a heat exchange device is installed inside the outer shell, with hot wastewater pipes installed inside the rotating support and heat exchange pipes installed inside the heat exchange device.

[0014] Furthermore, fins are installed on the heat exchange device, and fins that cooperate with those on the heat exchange device are installed on the rotating support.

[0015] Furthermore, the second sliders installed on both sides of the rotating bracket can rotate inside the grooves opened in the support plate.

[0016] Beneficial effects

[0017] Compared with the prior art, this utility model provides a waste heat recovery device for knitting dyeing and finishing equipment, which has the following beneficial effects:

[0018] This invention, by setting two sets of support plates on the outer shell, allows the rotating bracket to enter through the second sliders installed on both sides. The first and second baffles installed on the top and one side of the outer shell provide limiting positions. When the first sliders fixed on both sides of the first and second baffles move to the top of the waist-shaped groove, multiple sets of limiting blocks can fix the current positions of the first and second baffles, thus limiting the position of the rotating bracket. When cleaning or replacing the hot wastewater pipe is required, simply remove the limiting blocks to move the first and second baffles into the grooves opened on the outer shell, and the rotating bracket can be moved out along the grooves opened on the support plates, thereby achieving rapid replacement. This effectively solves the problems of inconvenience and reduced efficiency caused by traditional pipe fixing methods. Attached Figure Description

[0025] 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.

[0026] Example

[0027] like Figure 1-5 As shown in the figure, an embodiment of the present invention provides a waste heat recovery device for a knitting dyeing and finishing equipment, comprising: a shell 1, two sets of support plates 3 respectively fixed on both sides of the shell 1, a rotating bracket 2 installed between the two sets of support plates 3, and a first baffle 4 and a second baffle 5 respectively installed on both sides of the rotating bracket 2; further comprising: two sets of grooves respectively opened on the top and one side of the shell 1, the first baffle 4 and the second baffle 5 respectively installed inside the two sets of grooves, two sets of first sliders 6 respectively fixed on both sides of the first baffle 4 and the second baffle 5, two sets of waist-shaped slots respectively opened on both sides of the grooves opened on the shell 1, allowing the first sliders 6 fixed on both sides of the first baffle 4 and the second baffle 5 to move along the direction of the waist-shaped slots, the inside of the waist-shaped slots also having slot holes, and a limiting block 7 installed in the waist-shaped slots on both sides of the shell 1 through the slots, the limiting block 7 can limit the first sliders 6 on both sides when the first baffle 4 and the second baffle 5 move to the top;

[0028] Two sets of support plates 3, fixed on both sides of the outer casing 1, are provided with identical grooves. Second sliders 10, matching the dimensions of the grooves on the support plates 3, are installed on both sides of the rotating bracket 2, allowing the second sliders 10 to move within the grooves along their opening direction. Two sets of inlets and outlets are provided on both sides of the outer casing 1. A heat exchange device 11 is installed inside the outer casing 1. Heat exchange pipes 9 pass through both sides of the outer casing 1 and are installed inside the heat exchange device 11. Hot wastewater pipes 8 are installed inside the rotating bracket 2. Fins 12 are also provided inside the heat exchange device 11. Fins 12 that match those on the rotating bracket 2 are installed on the rotating bracket 2. When the rotating bracket 2 is installed inside the outer casing 1, the two sets of fins 12 are in contact through mutual engagement.

[0029] During processing, the hot wastewater pipe 8 only needs to be connected to the dyeing and finishing equipment in front, and the heat exchange pipe 9 needs to be connected to the externally installed water outlet pipe. When the wastewater with heat is transported from the dyeing and finishing equipment through the hot wastewater pipe 8, the fins 12 installed inside the rotating support 2 can collect the heat, and then the heat is transferred through the fins 12 installed on the rotating support 2 and the fins 12 that cooperate with the heat exchange device 11, thereby heating the cool water inside the heat exchange pipe 9, which can be used for subsequent drying steps in the dyeing and finishing process, playing the role of heat resource recovery.

[0030] After the equipment has been working for a certain period of time, impurities and reaction-induced buildup will accumulate inside the hot wastewater pipe 8 used to transport waste liquid. Cleaning of the inside of the hot wastewater pipe 8 is necessary. To do this, simply close the valve controlling the transport of hot wastewater, then disassemble both sides of the hot wastewater pipe 8. Next, remove the limiting blocks 7 installed in the waist-shaped slots on both sides of the outer casing 1. This allows the first baffle 4 and the second baffle 5 to move into the grooves on the outer casing 1, so that the first baffle 4 and the second baffle 5 no longer restrict the position of the rotating support 2. Then, simply insert another set of newly replaced rotating supports 2 through the grooves on the two side support plates 3. Due to the rotating nature of the rotating supports 2, the new set of rotating supports 2 can directly push the old set of rotating supports 2 out of the grooves on the other side of the support plate 3, thus achieving rapid replacement. This effectively replaces the hot wastewater pipe 8 and saves replacement time, effectively reducing the problem of decreased efficiency due to internal buildup. After replacement, return the first baffle 4 and the second baffle 5 to their original positions and reinsert the limiting blocks 7 to restrict their movement.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
