Abstract
Description
Technical Field
[0001] The invention relates to a freight elevator with sterilization and dust removal functions, in particular to a large-load clean freight elevator. Background Art
[0002] For some applications with high requirements for cleanliness, the elevator also needs to have disinfection and purification functions, so that the air in the elevator can be continuously disinfected and particulate matter can be removed to ensure a good environment in the elevator and reduce the possibility of the spread of infectious diseases. The current sterilization and purification method of the elevator is to install a purifier on the top of the car, and use the purifier to process the external air and send it into the car. At the same time, the air in the car is discharged to the outside through the air vents, thereby realizing the circulation and continuous purification of the air in the car, and preventing the external air from directly entering the car.
[0003] However, the above processing structure has certain defects in actual use. First, the purifier purifies the external air and then sends it into the car, which results in the air in the car being purified only once by the purifier, so that the cleanliness level in the car can only be maintained at level 10 or 100, which is difficult to meet the cleanliness requirements of the car environment in special occasions. Second, due to the low cleanliness of the external air, the power and power consumption of the purifier will be increased during processing. At the same time, a large amount of particulate matter in the air will remain in the purifier after purification and affect the subsequent purification quality, resulting in the manufacturer needing to frequently replace the filter or add filter agent to ensure the treatment effect of the purifier, thereby increasing the maintenance difficulty and maintenance cost of the elevator. Third, due to the presence of some large particles of dust and debris in the external air, such impurities will not only seriously increase the purification effect and stability of the purifier after entering the purifier with the air, but the purifier will also easily generate noise during the subsequent processing process, reducing the passenger experience.
[0004] For freight elevators with large load capacity and large accommodation space, the increase in space inside the car leads to higher requirements for the ventilation rate of the car, which not only requires further increase in the power and power consumption of the purifier, but also the noise will become more obvious as the specifications of the purifier increase, reducing the comfort and experience of the elevator.
[0005] Therefore, existing large-load sterilizing elevators have the problems of high power consumption, poor purification effect and high noise. Summary of the invention

DETAILED DESCRIPTION
[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.
[0029] Embodiment 1. A heavy-duty clean freight elevator, comprising: Figure 1-4 As shown, it includes an elevator car 1, the size of the elevator car 1 is 4500mm*3600mm*3600mm, a partition 2 is provided in the elevator car 1, one side of the partition 2 forms a carrying part 3, the other side of the partition 2 forms an air passage 4, the lower end of the air passage 4 is provided with an air inlet 5 connected to the carrying part 3, the top of the air passage 4 extends to the outside of the elevator car 1 and is provided with an air outlet 6, the outside of the air outlet 6 is connected to a purifier 8 located on the top of the elevator car 1 via an air pipe 7, and the air outlet end of the purifier 8 is connected to the carrying part 3.
[0030] The partition 2 and the side wall of the elevator car 1 have the same structure and both include baffles 9. A plurality of baffles 9 are connected to each other to form the partition 2 or the elevator car wall. Both ends of the baffles 9 are provided with bending portions 11 with C-shaped cross-sections. Adjacent baffles 9 are attached to each other and bolted together via the bending portions 11.
[0031] The upper and lower ends of the baffle plate 9 are both provided with a first cross beam 10, and the outer sides of the first cross beam 10 are respectively bolted to the top and bottom surfaces of the elevator car 1, and the two ends of the first cross beam 10 are buckled into the bent portion 11, and a mounting groove 12 is formed between the first cross beam 10 and the baffle plate 9, and a reinforcing rib plate 13 with a C-shaped cross section is buckled and connected in the mounting groove 12.
[0032] The air inlet 5 is located at the lower end of the shield plate 9 , and a filter screen 14 is connected to the air inlet 5 . The filter screen 14 is detachably connected to the shield plate 9 around it, and a second crossbeam 15 connected to the reinforcing rib plate 13 is provided in the mounting groove 12 above the filter screen 14 .
[0033] The partition 2 is symmetrically arranged on the left and right sides of the elevator car 1, a carrying part 3 is formed between the partitions 2 on both sides, an air passage 4 is formed between the partition 2 and the elevator car 1, and the number of the air outlets 6 is six and they are arranged side by side at the top of the air passages 4 on both sides, and each air outlet 6 is connected to a purifier 8, and the power of the purifier 8 is 175W.
[0034] An intermediate pipe 23 connected to the elevator car 1 is provided on the outer side of the air outlet 6 , one end of the intermediate pipe 23 is connected to the air passage 4 via the air outlet 6 , and the other end of the intermediate pipe 23 is connected to the air pipe 7 .
[0035] When this embodiment is in use, the purifier 8 extracts the air in the car, so that the air in the car enters the air passage 4 from the air inlet 5, passes through the air passage 4, the intermediate pipe 23 and the air pipe 7 in sequence and enters the purifier 8 for purification, and then the purifier 8 re-sends the purified air into the elevator car 1; so that the purifier 8 can circulate and purify the air in the car for multiple times during the treatment, thereby improving the treatment effect and cleanliness of this part of the air. At the same time, the air in the car basically does not participate in the exchange with the outside air during the treatment process, and the short-term internal and external air connection generated when the car is opened and closed will not excessively affect the cleanliness of the air in the car, so that the air in the car can reach the thousandth level of suspended particle cleanliness level (ISO CLass 6) selected for clean rooms and clean areas in the international standard ISO14644-1 after multiple purifications. At the same time, when the purifier 8 circulates and purifies this part of high-purity air, it can effectively reduce the power and electricity consumption during purification compared to the external air with lower cleanliness, and the loss of the filter and filter agent is also lower, thereby reducing the maintenance cost and power consumption of the elevator.
[0036] By setting the filter 14 at the air inlet 5, it can also separate the large volume impurities remaining in the car, prevent them from entering the purifier and reducing the purification effect, and ensure the purification stability of the purifier. When passengers are riding, the internal and external air exchange formed by each opening and closing of the elevator door can ensure sufficient oxygen content in the car, thereby avoiding the problem of insufficient oxygen caused by the internal circulation of air in the car.
