Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a heat exchanger protective device. Background Technology

[0002] Heat exchangers, as key equipment for heat transfer between hot and cold fluids, play an indispensable role in many industrial fields such as chemical, petroleum, power, and food.

[0003] Currently, most heat exchangers on the market suffer from a significant deficiency in their protective structure. In particular, the heat pipes are often exposed, which greatly increases the risk of burns due to accidental contact with the heat pipes, posing a serious health hazard to operators. Furthermore, heat exchangers exposed to the elements for extended periods easily accumulate large amounts of dust. This dust buildup not only affects the appearance of the heat exchanger but also reduces the heat transfer efficiency of the unit, thereby lowering overall performance, increasing energy consumption, and impacting production stability and economic efficiency.

[0004] To address the aforementioned issues, some patents have made corresponding improvements. For example, patent application number 202320161020.1 discloses a heat pipe with a protective structure. This device successfully protects the heat pipe of the heat exchanger by setting buffer and protective components, effectively reducing the risk of burns to others. Simultaneously, its equipped cleaning component can regularly clean the protective mesh, solving the problem of dust adhering to the mesh to some extent.

[0005] While this patent represents some progress in protection and cleaning, it still reveals significant shortcomings in practical applications. When the threaded rod drives the cleaning brush up and down to clean the protective mesh, a large amount of dust is generated. This dust disperses during cleaning, and some of it re-settles on the mesh after cleaning, affecting the cleaning effect and failing to completely eliminate the negative impact of dust on heat exchanger performance.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0007] The purpose of this invention is to provide a heat exchanger protection device.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A heat exchanger protection device, comprising:

[0010] An enclosing member, which encloses itself to form a protective groove, has two symmetrically arranged openings along a first direction; at least a portion of the enclosing member (such as the crossbar described below) can move along a predetermined annular path;

[0011] The support member is used to support the enclosure and also to seal the opening of the protective groove;

[0012] A driving member, acting on the enclosure, for causing at least a portion of the enclosure (such as the crossbar described below) to move along the predetermined annular path;

[0013] A cleaning component, connected to the support component, is used to clean the wall portion of the enclosure component;

[0014] A collection component, connected to the support component, is used to collect debris separated from the wall portion of the enclosure component;

[0015] A suction device, located on one side of the collection device, is used to draw debris separated from the wall of the enclosure toward the collection device.

[0016] The support is attached to the following crossbar or pulley.

[0017] This application uses heat exchangers as an example, but its application is not limited to heat exchangers.

[0018] The heat exchanger can be placed in a protective tank and protected by enclosure components to prevent the heat exchanger from being easily damaged and to prevent the heat pipes and other structures in the heat exchanger from injuring the operators.

[0019] The heat exchanger enters and exits the protective groove through an opening, and the protection of the heat exchanger is enhanced by support components.

[0020] In the above scheme, during the cleaning stage, the support member supports the enclosure member, the drive member drives at least part of the enclosure member to move along a predetermined annular path, the cleaning member is regarded as a stationary structure, when the enclosure member comes into contact with the cleaning member, the cleaning member causes the debris to separate from the enclosure member, and under the action of the suction member, the debris enters the collection member to complete the recycling.

[0021] This application completes the debris cleaning work through the support component, drive component and cleaning component to ensure the durable use of the enclosure component, and completes the debris recycling work through the collection component and suction component to avoid debris that has separated from the enclosure component from adhering to the enclosure component again, resulting in poor cleaning effect. At the same time, it avoids the impact on the operator's health due to debris being scattered in the air.

[0022] In a further technical solution, the support member includes two support plates symmetrically distributed along the first direction, and annular grooves are provided on the side surfaces of the two support plates that are close to each other. The two ends of the enclosure member are respectively inserted into the two annular grooves.

[0023] The annular groove forms the predetermined annular path.

[0024] The annular groove serves two purposes: firstly, it supports the enclosure, and secondly, it restricts the movement path of the enclosure, preventing it from shifting during movement.

[0025] A further technical solution is that the enclosure component includes:

[0026] Multiple crossbars are provided, and each crossbar is arranged along the predetermined annular path;

[0027] Connecting straps are attached to each of the crossbars.

[0028] The crossbars form the main body of the enclosure, and the protective groove is formed by the crossbars.

[0029] This embodiment does not limit whether the adjacent crossbars are tightly fitted, but this embodiment is mainly described with the adjacent crossbars tightly fitted, and gaps exist between the adjacent crossbars due to factors such as different surface roughness.

[0030] The connecting strips help the crossbars form a protective structure, preventing debris from easily entering the protective groove due to large gaps between adjacent crossbars. The connecting strips can be considered as a sleeve structure, fitted over the outside of each connecting strip.

[0031] In some implementations, adjacent crossbars are spaced apart. In this case, the number of crossbars required is reduced, the structural cost is reduced, and the need for cleaning the surface of the crossbar facing the center of the protective groove is increased, as debris falling off this surface can easily enter the outside of the protective groove.

[0032] In a further technical solution, the connecting strips are provided in multiples, and each connecting strip is distributed at intervals along the first direction.

[0033] The installation of multiple connecting straps can enhance the structural stability of the protective body formed by each crossbar, prevent the protective body from easily loosening, and further prevent debris from easily entering the protective groove.

[0034] In a further technical solution, the driving component includes:

[0035] Electric motor;

[0036] The drive roller is connected to the output end of the motor;

[0037] A raised structure is connected to the drive roller and is arranged corresponding to the crossbar.

[0038] In some embodiments, the crossbar has a toothed structure corresponding to the protrusion.

[0039] The motor is the driving source. The combination of the driving roller and the raised structure can be regarded as a gear, and the combination of each crossbar can be regarded as a ring rack. The driving source drives the gear, and the gear drives the ring rack to move along a predetermined ring path.

[0040] The gear-driven mechanism ensures stable movement of each crossbar along a predetermined circular path, facilitating the cleaning of each crossbar.

[0041] In some embodiments, the protrusion structure is configured as a plurality of protrusion structures, and each protrusion structure is uniformly distributed circumferentially around the axis of the drive roller.

[0042] In a further technical solution, the cleaning component includes brushes symmetrically arranged in the vertical direction, with the two brushes respectively located on the inner and outer sides of the protective groove.

[0043] Two brushes are located on the inner and outer sides of the protective groove, respectively. They can clean the inner and outer surfaces of each crossbar as it moves along a predetermined circular path, thus improving the cleanliness of the enclosure.

[0044] In a further technical solution, the collecting component has a feed inlet;

[0045] In the vertical direction, the projection of the brush is completely covered by the projection of the feed inlet.

[0046] The collection component can be understood as a collection bin, which has a collection trough and the inlet is connected to the collection trough.

[0047] This embodiment actually restricts the position of the brushes. The two brushes are positioned directly above the feed inlet, which facilitates the separation of debris from the crossbar and their entry into the collection container, thereby increasing the amount of debris recovered.

[0048] In a further technical solution, the collecting component has a discharge port, the suction component is configured as a fan, and the air inlet of the fan is connected to the discharge port.

[0049] Under the action of the blower, debris enters the collection unit through the feed inlet, further increasing the amount of debris recovered. The working principle of the blower is explained in the existing description.

[0050] In a further technical solution, each end of the crossbar is connected to a pulley, and the pulleys are all fitted into the wall of the corresponding annular groove.

[0051] Compared to using a crossbar to fit against the wall of an annular groove, using a pulley to fit against the wall of an annular groove has the following effects: as the enclosure moves along a predetermined annular path, the pulley reduces the friction between the enclosure and the annular groove, thereby reducing the driving pressure of the drive component and extending its service life.

[0052] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0053] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0054] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0055] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0056] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0057] The working principle and advantages of this utility model are as follows:

[0058] During the cleaning phase, the support member supports the enclosure member, and the drive member drives at least a portion of the enclosure member to move along a predetermined annular path. The cleaning member is considered a stationary structure. When the enclosure member comes into contact with the cleaning member, the cleaning member causes the debris to separate from the enclosure member. Under the action of the suction member, the debris enters the collection member to complete the recycling.

[0059] This application completes the cleaning of debris through support components, drive components, and cleaning components, ensuring the long-term use of the enclosure. It also completes the debris recycling through collection components and suction components, preventing debris separated from the enclosure from re-adhering to the enclosure and resulting in poor cleaning effect. This completely solves the negative impact of dust on the performance of the heat exchanger, while also preventing the spread of debris in the air from affecting the health of the operators.

[0060] In summary, this application improves the final debris removal effect and protects the health of operators. Attached Figure Description

[0069] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0070] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0071] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0072] See Figures 1-7 A heat exchanger protection device, comprising:

[0073] Enclosing member 1, which encloses itself to form a protective groove 11, and along a first direction, the protective groove 11 has two symmetrically arranged openings 111; at least a portion of the enclosing member 1 (such as the crossbar described below) can move along a predetermined annular path;

[0074] Support member 2 is used to support the enclosure member 1 and also to block the opening 111 of the protective groove 11;

[0075] The driving member 3 acts on the enclosure member 1 to cause at least a portion of the enclosure member 1 to move along the predetermined annular path;

[0076] Cleaning component 4, connected to the support component 2, is used to clean the wall of the enclosure component 1;

[0077] The collecting component 5, connected to the supporting component 2, is used to collect debris separated from the wall of the enclosing component 1;

[0078] A suction element 6 is provided on one side of the collection element 5 to draw debris separated from the wall of the enclosure element 1 toward the collection element 5.

[0079] The first direction is Figure 1 In the x-direction.

[0080] This application uses heat exchangers as an example, but its application is not limited to heat exchangers.

[0081] The heat exchanger can be placed inside the protective tank 11 and protected by the enclosure 1 to prevent the heat exchanger from being easily damaged and to prevent the heat exchanger from injuring the operators.

[0082] The heat exchanger enters and exits the protective groove 11 through the opening 111, and the support member 2 enhances the protection of the heat exchanger.

[0083] In some embodiments, the collecting element 5 is disposed at the bottom of the support element 2.

[0084] In some embodiments, the suction member 6 is disposed on one side of the collection member 5 along the length direction of the collection member 5.

[0085] During the cleaning phase, the support member 2 supports the enclosure member 1, and the driving member 3 drives at least a portion of the enclosure member 1 to move along a predetermined annular path. The cleaning member 4 is considered a stationary structure. When the enclosure member 1 comes into contact with the cleaning member 4, the cleaning member 4 causes the debris to separate from the enclosure member 1. Under the action of the suction member 6, the debris enters the collection member 5 to complete the recycling.

[0086] This application completes the cleaning of debris through the support component 2, the drive component 3 and the cleaning component 4, ensuring the long-term use of the enclosure component 1. It also completes the debris recycling through the collection component 5 and the suction component 6, preventing debris separated from the enclosure component 1 from re-adhering to the enclosure component 1 and resulting in poor cleaning effect. This completely solves the negative impact of dust on the performance of the heat exchanger, and at the same time avoids the impact of debris on the health of the operators due to the dispersion of debris in the air.

[0087] It should be emphasized that during cleaning, the enclosure 1 moves while the cleaning component 4 remains stationary (not considering the movement of the bristles 411), which further limits the spread of debris and facilitates the recycling of debris.

[0088] Miscellaneous items refer to substances such as dust.

[0089] See Figure 1 , Figure 7 In this embodiment, the support member 2 includes two support plates 21 symmetrically distributed along the first direction. The two support plates 21 are provided with annular grooves 211 on their adjacent side surfaces. The two ends of the enclosure member 1 are respectively inserted into the two annular grooves 211.

[0090] The annular groove 211 forms the predetermined annular path.

[0091] The annular groove 211 provides support for the enclosure 1 and restricts its movement path, preventing it from shifting during movement.

[0092] See Figure 3 , Figure 4 In this embodiment, the enclosure 1 includes:

[0093] Multiple crossbars 12 are provided, and each crossbar 12 is arranged along the predetermined annular path;

[0094] The connecting strap 13 is attached to each of the crossbars 12.

[0095] The crossbars 12 constitute the main body of the enclosure 1, and the protective groove 11 is formed by the enclosing of each crossbar 12.

[0096] This embodiment does not limit whether the adjacent crossbars 12 are tightly fitted together, but this embodiment mainly describes the case where the adjacent crossbars 12 are tightly fitted together, and there are gaps between the adjacent crossbars 12 due to factors such as different surface roughness.

[0097] The connecting strap 13 can make each crossbar 12 form a protective body, which can prevent the large gap between each adjacent crossbar 12 from causing debris to easily enter the protective groove 11, and can also facilitate the transfer of each crossbar 12.

[0098] The connecting belt 13 is a ring belt, which can be a stainless steel woven belt. The connecting belt 13 can be movably sleeved or fixedly sleeved on the outside of each crossbar 12. Each crossbar 12 can be arranged at intervals or closely attached to the inside of the connecting belt 13. There are no restrictions on the implementation method. For example, a partition block can be set between two crossbars 12.

[0099] In some embodiments, the crossbar 12 is made of metal, such as copper.

[0100] In some embodiments, adjacent crossbars 12 are spaced apart. In this case, the number of crossbars 12 required is reduced, the structural cost is reduced, and the cleaning requirement for the side surface of the crossbars 12 facing the center of the protective groove 11 is increased, as debris falling off this surface can easily enter the outside of the protective groove 11.

[0101] See Figure 3 , Figure 4 In this embodiment, there are multiple connecting strips 13, and each connecting strip 13 is distributed at intervals along the first direction.

[0102] The arrangement of multiple connecting straps 13 can enhance the structural stability of the protective body formed by each crossbar 12, prevent the protective body from easily becoming loose, and further prevent debris from easily entering the protective groove 11.

[0103] See Figure 1 , Figure 3 In this embodiment, the driving component 3 includes:

[0104] Motor 31;

[0105] The drive roller 32 is connected to the output end of the motor 31;

[0106] The protruding structure 33 is connected to the drive roller 32 and is provided corresponding to the crossbar 12.

[0107] In some embodiments, the crossbar 12 has a toothed structure corresponding to the protrusion 33.

[0108] The motor 31 is the driving source. The combination of the driving roller 32 and the protruding structure 33 can be regarded as a gear. The combination of each crossbar 12 can be regarded as a ring rack. The driving source drives the gear, and the gear drives the ring rack to move along a predetermined ring path.

[0109] The gear-driven mechanism ensures stable movement of each crossbar 12 along a predetermined circular path, facilitating the cleaning of each crossbar 12.

[0110] In some embodiments, the protrusion structure 33 is provided in multiple ways, and each protrusion structure 33 is evenly distributed in a circular pattern around the axis of the drive roller 32.

[0111] The specific arrangement of the driving component 3 can be referred to the attached figure. For example, holes can be opened on the support plate 21 to correspond to the motor 31, and the driving roller 32 can be set between the collecting component 5 and the enclosing component 1.

[0112] See Figure 4 In this embodiment, the cleaning component 4 includes brushes 41 symmetrically arranged in the vertical direction, with the two brushes 41 respectively located on the inner and outer sides of the protective groove 11.

[0113] The brush 41 is always in contact with the enclosure 1.

[0114] The brush 41 has bristles 411, which is an existing feature and will not be described in detail here.

[0115] Two brushes 41 are respectively located on the inner and outer sides of the protective groove 11, and can clean the inner and outer surfaces of each crossbar 12 as each crossbar 12 moves along a predetermined annular path, thereby improving the cleaning degree of the enclosure 1.

[0116] See Figure 4 , Figure 6 In this embodiment, the collecting component 5 has a feed inlet 51;

[0117] In the vertical direction, the projection of the brush 41 is completely covered by the projection of the feed inlet 51.

[0118] The collecting component 5 can be understood as a collecting bin, which has a collecting trough 53 and an inlet 51 connected to the collecting trough 53.

[0119] This embodiment actually restricts the position of the brushes 41. The two brushes 41 are positioned directly above the feed inlet 51, which facilitates the separation of debris from the crossbar 12 and their entry into the collection container 5, thereby increasing the amount of debris recovered.

[0120] See Figure 5 In this embodiment, the collecting component 5 has a discharge port 52, and the suction component 6 is a fan, with the air inlet of the fan connected to the discharge port 52.

[0121] Under the action of the blower, debris enters the collection unit 5 through the feed inlet 51, further increasing the amount of debris recovered. The working principle of the blower is described in the existing instructions.

[0122] In this embodiment, each of the crossbars 12 is connected to a pulley (not shown in the figure) at both ends, and the pulleys are all in contact with the wall of the corresponding annular groove 211.

[0123] Compared to using a crossbar 12 to fit against the wall of the annular groove 211, using a pulley to fit against the wall of the annular groove 211 has the following effects: during the movement of the enclosure 1 along the predetermined annular path, the pulley reduces the friction between the enclosure 1 and the annular groove 211, thereby reducing the driving pressure of the drive component 3 and extending the service life of the drive component 3.

[0124] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
