[0027] The energy-saving drying device for printing workshop provided by the utility model will be described in detail below in combination with the drawings and specific embodiments. It should be noted that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and other alternative ways can also be used by the skilled in the art to implement some known technologies; and the drawings are only used to more specifically describe the embodiments, and are not intended to specifically limit the utility model.

[0028] It should be noted that in the specification, "one embodiment", "embodiment", "exemplary embodiment", "some embodiments" and the like indicate that the described embodiments can include specific features, structures or characteristics, but not necessarily every embodiment includes the specific features, structures or characteristics. In addition, when describing specific features, structures or characteristics in combination with embodiments, it should be within the knowledge of the skilled in the related art to realize such features, structures or characteristics in combination with other embodiments (whether or not explicitly described).

[0029] Generally, the terms can be understood at least partly from the use in the context. For example, depending at least partly on the context, the term "one or more" used herein can be used to describe any feature, structure or characteristic in the singular sense or can be used to describe a combination of features, structures or characteristics in the plural sense. In addition, the term "based on" can be understood as not necessarily conveying a set of exclusive factors, but can instead allow the existence of other factors not necessarily explicitly described, at least partly depending on the context.

[0030] It will be understood that the meanings of “on,” “over,” and “above” in the present invention should be interpreted in the broadest manner, so that “on” means not only “directly on” something but also includes the meaning of being “on” something with intervening features or layers, and “on” or “above” means not only “on” or “above” something but also includes the meaning of being “on” or “above” something with no intervening features or layers.

[0031] Additionally, spatially relative terms such as "below," "beneath," "lower," "above," and "upper" may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as illustrated in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially relative descriptors used herein should be similarly interpreted accordingly.

[0032] like Figures 1-4 As shown, an embodiment of the present invention provides an energy-saving drying device for a printing workshop, comprising an air pump 1 and three drying boxes 2. An air inlet pipe 4 and an air outlet pipe 6 are fixed to each end of the drying box 2. The air pump 1 is connected to the air inlet pipe 4 of the first drying box 2, and adjacent drying boxes 2 are sequentially connected via connecting pipes 3, so that the airflow blown out by the air pump 1 can be reused multiple times in multiple drying boxes 2, which helps to reduce energy consumption. At the same time, a heating mechanism 5 is provided on the air inlet pipe 4. The heating mechanism 5 is an electric heating wire installed in the air inlet pipe 4, which can heat the airflow to the temperature required for drying PVC printed products. In the drying boxes 2 located at the second and third stations, the heating degree of the heating mechanism 5 varies according to the heat consumption of the upper level, and is mainly used for secondary heating to achieve heat supplementation, so as to avoid the problem of low heat and poor drying effect of the reused hot air.

[0033] Meanwhile, a base plate 7 is closely mounted on the outlet pipe 6. A handle 702 is fixed to the upper end of the base plate 7, and a filter 701 is fixed to the lower end of the base plate 7, which is inserted into the outlet pipe 6. The filter 701 contains activated carbon. Two filters 701 are provided. The two filters 701 are curved filter plates arranged in sequence along the direction of the hot air. The two filters 701 face opposite directions and are staggered.

[0034] In addition, the air pump 1 has symmetrical inlet and outlet ports 201 on either side. A movable plate 8 is mounted on the top of each inlet and outlet 201, allowing for vertical movement. Multiple insulation strips 801 are secured to the bottom edge of each plate. A vertical screw 9 rotates on the top of each plate 8, and a fixed edge 202 is secured to the top of the drying box 2, through which the screw 9 extends vertically. Thus, the movable plate 8 can be moved up and down at the inlet and outlet 201 by rotating the screw 9, adjusting the size of the inlet and outlet.

[0035] The working principle provided by the utility model is that the energy-saving drying device for the printing workshop, when in use, the air pump 1 and several connected drying boxes 2 can make the hot air pass through the multiple drying boxes 2, so as to achieve multi-stage utilization, and cooperate with the heating mechanism 5 provided on the air inlet pipe 4 and the base plate 7 provided on the air outlet pipe 6, so as to supplement the heat and filter the hot air used multiple times, thereby ensuring the utilization effect of the hot air.

[0036] At the same time, the movable plate 8 that can move up and down and is set on the top of the inlet and outlet 201 can conveniently adjust the size of the inlet and outlet according to the specifications of the PVC printed products, which is conducive to ensuring the drying effect inside the drying box 2 and is flexible to use.

[0037] In summary, compared with the existing technology, this device can improve the utilization efficiency of hot air energy, help reduce energy consumption, save energy and protect the environment.

[0038] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention. To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
