Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a packaging room for the production of dicalcium phosphate. Background Technology

[0002] Currently, dicalcium phosphate is generally produced as powder granules, then packaged in bags before being sold. Therefore, the packaging process for dicalcium phosphate is similar to that of conventional powder materials, involving temporary storage, bagging and filling, sealing, and warehousing after production. Bagging and filling, and sealing, are usually done continuously. Although there are dedicated automatic bagging packaging machines in the industry, such as patent CN 218086109 U - A Fully Automatic Phosphate Fertilizer Packaging, while these can free up workers, the overall equipment cost is enormous. Furthermore, these machines use an adsorption method for bagging, and the packaging bags are generally woven bags made of PE or PP materials. Gaps exist between the different webbing on the surface, and dust adheres, making it easy for the woven bags to fall off during adsorption. Therefore, a worker is needed to handle unexpected bag falls. For smaller manufacturers, bagging is still generally done manually. Although this is physically demanding and the working environment is harsh, the bagging quality is reliable, and it can handle unexpected situations. Therefore, both manual and automated bagging and filling currently require human intervention, only the intensity of labor differs.

[0003] Because dicalcium phosphate is a powder, the filling site is prone to dust. Although some filling equipment has a dust extraction function, such as the patent CN202020622444.X - a lifting dust collection and recovery powder packaging machine, the overall working environment is still very harsh, and workers need to wear dust masks. Especially in summer, during actual production, the dicalcium phosphate powder that has just been dried and entered the storage tank is at a certain temperature. Although it is generally allowed to cool naturally in the storage tank before packaging, if the demand is greater than or close to the production capacity, the dicalcium phosphate powder in the storage tank does not have enough time to cool naturally. In summer, direct sunlight can also heat the dicalcium phosphate powder inside the storage tank, resulting in very high temperatures in the area where the packaging machine is located. During the packaging process, dust easily adheres to the sweat on the workers' skin and drips down their bodies, making the workers feel hot and sticky. Therefore, the working environment is particularly harsh. If fans are installed on-site for cooling, the airflow from the fans will easily blow away dust, making the dust environment even more dusty; if air conditioning is used, its open structure will easily lead to waste of cooling air and high overall production costs. Utility Model Content

[0004] In order to overcome one of the shortcomings of the prior art, the purpose of this utility model is to provide a packing room for the production of dicalcium phosphate. The working environment of the packing room for the production of dicalcium phosphate is relatively comfortable and friendly, which can effectively reduce the labor intensity of workers.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] Furthermore, an electrostatic precipitator is installed on the side of the deposition box near the suction pipe.

[0009] Furthermore, the dust collector bag divides the interior of the deposition air box into a deposition zone and an air outlet zone, the suction circulating fan is connected to the air outlet zone, and the outlet end of the suction pipe is connected to the deposition zone.

[0026] Dust removal device 40, suction pipe 41, sedimentation air box 42, suction circulating fan 43, dust collector bag 44, return pipe 45, electrostatic precipitator 46, sedimentation zone 47, air outlet zone 48, ash discharge valve 49, suction hood 4a. Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] Reference Figures 1 to 3 The packaging room shown includes a main building 10 and a powder filling machine 20 installed on the main building 10. The filling end of the powder filling machine 20 is located inside the main building 10. It also includes a cold air supply device 30 and a dust extraction device 40. The air outlet of the cold air supply device 30 and the suction end of the dust extraction device 40 are both connected to the internal space of the main building 10. The exhaust end of the dust extraction device 40 is connected to the internal space of the main building 10 through a return pipe 45.

[0029] The main building 10 can be composed of conventional sandwich panels and a main frame, facilitating assembly and subsequent dismantling. The main building 10 surrounds the filling end of the powder filling machine 20 and has operable doors and windows for easy access and observation of the interior. The conveying equipment used with the powder filling machine 20 conveys the product outward through a corresponding opening in the main building 10. To prevent internal cold air leakage, a roller shutter can be installed on this opening. The powder filling machine 20 in this application is a conventional device, such as patent CN202020622444.X - A Lifting Dust Removal and Recycling Powder Packaging Machine, which is not detailed herein. Furthermore, the cold air supply device 30 is either an air conditioning system or a water-cooled fan. In practice, air conditioning systems have high energy consumption and are unsuitable for industrial production environments. Therefore, this application uses a water-cooled fan, which has relatively low operating costs. Examples include patents CN201820021576.X - an industrial air cooler with good dustproof effect or CN202322370246.5 - an air cooler with a leak-proof structure, which will not be detailed here. Of course, in the above embodiments, two refrigeration systems can be used simultaneously, which can be designed according to actual usage requirements.

[0030] The packaging room for dicalcium phosphate production adds a closed main building 10 to the existing filling machine. This prevents dust from escaping, facilitating subsequent processing, and also avoids disorderly leakage of cold air supplied by the cold air supply device 30, reducing cold air loss and improving comfort. Furthermore, a dust extraction device 40 is designed to remove dust raised at the interface between the powder filling machine 20 and the packaging bag during the filling process, reducing the overall dust level inside the main building 10 and improving the safety of the working environment. Simultaneously, through the return pipe 45, the cold air discharged by the dust extraction device 40 can flow back into the interior space of the main building 10, achieving cold air circulation and reducing the cooling energy consumption of the cold air supply device 30.

[0031] See Figure 3 To better cool the entire interior of the building structure 10 and reduce the direct impact of cold air on the filling port of the powder filling machine 20, in one embodiment of this application, a ventilation interlayer 11 is provided at the top of the interior of the building structure 10. The ventilation interlayer 11 has annular grooves 12 on its periphery, and several air outlets 13 are provided on the side wall of the ventilation interlayer 11 near the annular grooves 12. The ventilation interlayer 11 is connected to the return pipe 45 and the air outlet of the cold air supply device 30. This periphery exhaust method allows the cold airflow to pass through the suction dust removal device 40 from the periphery of the building structure 10 towards the center, which helps to draw dust generated at the filling port of the powder filling machine 20 into the suction dust removal device 40, ensuring effective dust removal. Meanwhile, within the entire building body 10, the area where the filling port of the powder filling machine 20 is located has the highest temperature, while the temperature around the building body 10 is low. At this time, the cold air flows from the low-temperature periphery to the high-temperature central area, which can greatly improve the cooling effect and ensure the comfort of the staff.

[0032] In the above embodiment, to prevent dust from entering the ventilation interlayer 11 from the air outlet 13 when the cold air supply device 30 is not in use during winter, a protective cover 14 is hinged to the air outlet 13. The protective cover 14 can automatically seal the air outlet 13 due to its own weight. In fact, during normal production, the suction dust removal device 40 is basically open all year round, and its main purpose is dust removal. Therefore, the suction dust removal device 40 can still work normally during production and filling in winter.

[0033] Furthermore, in the actual production process, the dicalcium phosphate powder that has just been dried and entered the storage tank has a certain temperature. Although it is generally allowed to cool naturally through the storage tank during the actual packaging process, if the demand is greater than or close to the production capacity, the dicalcium phosphate powder in the storage tank does not have enough time to cool naturally. Alternatively, direct sunlight in summer can heat the dicalcium phosphate powder inside the storage tank. Therefore, the filling port temperature of the powder filling machine 20 is higher than room temperature. In order to reduce the temperature of other components of the powder filling machine 20, the temperature is lowered from the main building 10. To reduce heat radiation to workers' heads, the ventilation interlayer 11 is divided into a circulation channel 16 and an insulation zone 17 by a partition 15. The circulation channel 16 is located on the periphery of the insulation zone 17. The air outlet 13 is connected to the circulation channel 16, and the circulation channel 16 and the insulation zone 17 are connected. The air outlet of the cold air supply device 30 is connected to the circulation channel 16, and the return pipe 45 is connected to the insulation zone 17. An overflow air outlet 18 is provided on the insulation zone 17. The filling end of the powder filling machine 20 passes through the insulation zone 17 and is placed inside the building body 10. The insulation zone 17 contains a certain amount of cool air, which has a heat insulation effect and can effectively reduce the air temperature in the worker's head area and the overall heat radiation.

[0034] See Figures 1 to 3To achieve dust and cold air recovery and utilization, in one embodiment of this application, the suction dust removal device 40 includes a suction pipe 41, a sedimentation box 42, and a suction circulation fan 43. At least one suction pipe 41 is provided, with its suction end positioned around the periphery of the powder filling machine 20. The other end of all suction pipes 41 is connected to one side of the sedimentation box 42. The inlet end of the suction circulation fan 43 is connected to the other side of the sedimentation box 42. A dust collector bag 44 is installed inside the sedimentation box 42, separating the inlet end of the suction circulation fan 43 from the outlet end of the suction pipe 41. The outlet end of the suction circulation fan 43 is connected to the internal space of the building body 10 via a return pipe 45. In this application, two suction pipes 41 are preferably provided, with the suction ends of the two suction pipes 41 and the worker's operating station arranged in a triangular pattern. This ensures both effective dust removal and sufficient operating space for the worker. In this application, the suction end of the suction pipe 41 is fixed to the outer periphery of the filling end of the powder filling machine 20 by a movable bracket. To facilitate adjustment of the position of the suction end of the suction pipe 41, a universal rod can be used for connection and fixation. To increase the suction effect, a suction hood 4a is provided on the suction end of the suction pipe 41. In an improved embodiment of this application, to cope with filling operations in cold regions, a switch valve can be installed on the return pipe 45 to cut off the connection between the outlet of the suction circulating fan 43 and the main building 10 in winter; simultaneously, the return pipe 45 is provided with an outward discharge channel, which can also be closed to adapt to summer use.

[0035] Furthermore, in the above embodiments, both the sedimentation chamber 42 and the suction circulation fan 43 are located outside the main building 10, thereby reducing noise inside the main building 10 and improving comfort. The sedimentation chamber 42 is essentially a filter container, with the dust collector bag 44 serving as the filter structure.

[0036] In the above embodiments, for ease of explanation, the dust collector bag 44 divides the interior of the deposition air box 42 into a deposition zone 47 and an air outlet zone 48. The suction circulating fan 43 is connected to the air outlet zone 48, and the outlet end of the suction pipe 41 is connected to the deposition zone 47. In this embodiment, for ease of replacement of the dust collector bag 44 later, the dust collector bag 44 is actually mounted on a frame inserted into the deposition air box 42, which facilitates the removal and placement of the dust collector bag 44.

[0037] To further improve the dust removal effect, an electrostatic precipitator 46 is installed inside the deposition air box 42 near the suction pipe 41. The electrostatic precipitator 46 is a conventional dust removal device, which will not be described in detail here, but can be referred to in the electrostatic precipitator devices on the market. In the above embodiment, in order to facilitate the discharge of the dust deposited in the deposition zone 47, a dust discharge valve 49 is provided at the bottom of the deposition zone 47.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
