[0001] This utility model relates to the field of solid dosage form technology, specifically a heat recovery device for solid dosage form workshops. Background Technology

[0002] Solid dosage forms generally refer to solid drug forms used for oral administration in the pharmaceutical industry, including tablets, capsules, granules, powders, granules and pellets, etc. The production of these preparations may involve a series of process steps, such as mixing, granulation, tableting, coating, drying, etc.

[0003] In solid dosage form workshops, the high-temperature and humid air discharged from equipment such as granule dryers, fluidized bed dryers, and ovens is directly released into the workshop. Since there is no corresponding heat recovery device in the workshop, a large amount of heat is lost, resulting in some waste. At the same time, it causes the temperature in the solid dosage form workshop to rise, increasing the discomfort in the workshop. Therefore, we need to propose a heat recovery device for solid dosage form workshops. Utility Model Content

[0004] The purpose of this invention is to provide a heat recovery device for a solid dosage form workshop.

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a heat recovery device for a solid dosage form workshop, comprising:

[0024] A heat recovery shell 1 and a heat exchange mechanism 2 installed inside the heat recovery shell 1. A spiral blade 9 is provided between the heat recovery shell 1 and the heat exchange mechanism 2. The inner cavity of the heat recovery shell 1 forms a water supply channel 10 through the heat exchange mechanism 2 and the spiral blade 9.

[0025] An air intake guide ring 11, located at the bottom of the inner cavity of the heat recovery housing 1, diverts the hot and humid air generated by the equipment.

[0026] The heat exchange mechanism 2 includes a heat exchange inner cylinder 22 installed on the upper surface of the air inlet guide ring 11. The spiral blades 9 are fixedly connected to the outer side of the heat exchange inner cylinder 22. Multiple sets of heat-absorbing fins 23 are fixedly connected to the inner wall of the heat exchange inner cylinder 22, and a flow channel 24 for the flow of humid and hot air is provided between two adjacent sets of heat-absorbing fins 23. A cover 21 for sealing the upper opening of the heat recovery shell 1 is fixedly connected to the top of the heat exchange inner cylinder 22. The multiple sets of heat-absorbing fins 23 can increase the contact area with humid and hot air, thereby facilitating the heat exchange of the humid and hot air to the water in the water inlet channel 10, realizing the heating of the water in the water inlet channel 10, and realizing the efficient utilization of heat energy. At the same time, the condensate generated by the heat exchange of the heat-absorbing fins 23 will fall into the water collection hopper 7 under its own weight for collection and utilization.

[0027] The inner cavity of the heat exchange inner cylinder 22 is equipped with a resistance-increasing mechanism 8 to slow the upward flow of humid and hot air. The upper surface of the cover 21 is equipped with an exhaust pipe 3 for the air to be discharged after heat exchange. The lower end of the heat recovery shell 1 is equipped with a water collection hopper 7 for collecting the condensate generated by heat exchange. The resistance-increasing mechanism 8 can increase the residence time of humid and hot air in the heat exchange inner cylinder 22, thereby increasing the heat exchange effect of humid and hot air and ensuring the efficient utilization of humid and hot air. The air after heat loss is discharged through the exhaust pipe 3.

[0028] An annular air passage 13 is formed between the air inlet guide ring 11 and the heat recovery shell 1. A square tube 5 for equipment connection is provided on the outer side of the heat recovery shell 1. Multiple sets of oblique air holes 12 are opened on the air inlet guide ring 11 and communicate with the inner cavity of the heat exchange inner cylinder 22. The main view section of the annular channel is L-shaped. The annular air passage 13 formed between the air inlet guide ring 11 and the heat recovery shell 1 can divert the humid and hot air, so that the humid and hot air can be introduced into the heat exchange inner cylinder 22 through the multiple sets of oblique air holes 12. The horizontal height of the air inlet end of the oblique air hole 12 is higher than the horizontal height of the air outlet end, which can prevent the backflow of condensate.

[0029] It also includes a water supply mechanism 4 that guides water into the water intake channel 10. The water supply mechanism 4 includes an inlet pipe 42 located at the upper outer side of the heat recovery shell 1. A water pump 41 is installed on the inlet pipe 42 to transport water. An outlet pipe 6 connected to the water intake channel 10 is installed at the lower outer side of the heat recovery shell 1. The water pump 41 can introduce water that needs to be heated from the outside into the water intake channel 10, thereby improving the efficiency of water heating. The water flows from top to bottom, while the hot and humid air flows from bottom to top. Since the hot and humid air will be cooled before being discharged, it can preheat the water that has just entered the water intake channel 10, thereby improving the heating effect of the water. The heated water is discharged and utilized through the drain pipe.

[0030] The resistance-increasing mechanism 8 includes a T-rod 81 fixedly connected to the upper end of the inner side of the heat exchange inner cylinder 22. Multiple sets of baffles 82 are fixedly connected to the outer side of the T-rod 81. The multiple sets of baffles 82 are arranged at equal intervals. The outer diameter of the lowest baffle 82 is larger than that of the upper baffle 82, and the baffle 82 is a conical disc. The upper sets of baffles 82 have the same spacing, which can reduce the upward speed of the humid and hot air, thereby increasing the heat exchange time of the humid and hot air and improving the heat exchange efficiency. The lowest baffle 82 can maximize the expansion of the humid and hot air when it first enters the heat exchange inner cylinder 22, so that the humid and hot air enters the flow channel 24 between adjacent heat absorption fins 23, which facilitates the heat absorption fins 23 to absorb heat from the humid and hot air.

[0031] The water collection hopper 7 is a conical hopper. A buffer ring channel 14 for condensate to flow into is fixedly connected to the inner wall of the water collection hopper 7. The buffer ring channel 14 can collect the condensate. After the condensate overflows from the buffer ring channel 14, it is collected in the water collection hopper 7. The humid and hot air, guided by the inclined air hole 12, heats the condensate falling into the buffer ring channel 14, so that the heated condensate is discharged, which facilitates the collection and utilization of condensate and improves the resource utilization rate.

[0032] In use, the heat recovery shell 1 is connected to the equipment generating humid air via the equipment connection square tube 5, facilitating the entry of humid air into the heat recovery shell 1. Guided by the annular air passage 13, the humid air enters the heat exchange inner cylinder 22 through multiple sets of oblique air holes 12 and rises along the inner cavity of the heat exchange inner cylinder 22. During this ascent, multiple sets of baffles 82 slow down the rising speed of the humid air, thereby increasing the contact time between the humid air and the heat exchange inner cylinder 22 and the heat absorption fins 23. Meanwhile, water pumped into the water inlet channel 10 by the water pump 41 exchanges heat through the heat exchange inner cylinder 22 and the heat absorption fins 23, thus... The spiral blades 9 increase the flow path of water in the water inlet channel 10, thereby improving the heating effect of the water and the efficiency of heat recovery of workshop equipment. During the continuous heat exchange process, condensate will be generated and condensed on the heat absorption fins 23 and the turbulence plate 82. Since the condensate has a certain amount of heat energy in the heat exchange inner cylinder 22, it falls into the buffer ring channel 14 under its own weight. The humid and hot air introduced through the inclined air hole 12 will further heat the condensate, so that the heated condensate can be discharged and the condensate can be recycled, thus improving the utilization rate of heat energy.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
