Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning and purification, and in particular to an elevator with a hoistway positive and negative pressure balanced internal circulation polluted air treatment and purification device. Background Art

[0002] Currently, elevators commonly use T-shaped guide rails, secured to the elevator car by guide shoes. Industrial oil is used as a lubricant between the T-shaped guide rails and the guide shoes, and the elevator wire ropes are also treated with industrial oil for rust prevention. However, the lubricating oil in the bearings of the elevator's traction sheave, car return pulley, counterweight return pulley, and other components evaporates into the hoistway air over time and temperature, mixing with the oil molecules. Furthermore, the elevator's traction main unit also produces harmful gases when powered on.

[0003] As elevator cars move up and down within a relatively narrow shaft, a positive and negative pressure differential forms between the upper and lower parts of the car. When positive pressure airflow occurs, toxic oil fumes volatile within the shaft are squeezed into the room through the gaps in the elevator doors, contaminating the indoor air. Industrial oil molecules mix with indoor air and are inhaled into the respiratory tract and lungs. These molecules can attach to the respiratory tract and lungs, increasing the risk of cancer. Inhalation of industrial oil molecules can damage human organs and even increase the risk of lung cancer. Purification of the air within the elevator shaft is necessary, but how to do this remains a technical challenge in this field. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an elevator with a hoistway positive and negative pressure balanced internal circulation polluted air treatment and purification device.

[0007] The two ends of the other circulating air purification mechanism are respectively penetrated by a lower air outlet pipe and an upper air inlet pipe;

[0008] One end of the lower air outlet pipe and the upper air inlet pipe are connected to the upper air inlet assembly of the car and the upper air outlet assembly of the car respectively;

[0009] One end of the lower air inlet pipe and the upper air outlet pipe are connected to the lower air inlet assembly of the car and the lower air outlet assembly of the car respectively;

[0010] Fans are installed on both the upper air outlet pipe and the lower air outlet pipe.

[0011] Compared with the existing technology, this application also realizes the purification of air when the box assembly descends and the purification of air when the box assembly rises by setting two circulating air purification mechanisms, and also realizes the purification of air when the box assembly descends and the purification of air when the box assembly rises by setting a fan, and effectively extracts gas and improves gas fluidity, which helps to fully realize the purification of air.

[0012] An elevator with a hoistway positive and negative pressure balanced internal circulation polluted air treatment and purification device, comprising a box assembly, on which a purification system, an elevator electronic control system and a hoisting mechanism are installed;

[0014] The other side of the circulating air purification mechanism is penetrated by a lower air outlet pipe fitting and an upper air outlet pipe fitting, one end of the lower air outlet pipe fitting extends to the lower end of the box assembly, one end of the lower air outlet pipe fitting extending to the lower end of the box assembly is connected to the car lower air outlet assembly, the car lower air outlet assembly is installed at the lower end of the box assembly, one end of the upper air outlet electric control valve is connected to the car upper air outlet assembly, and the car upper air outlet assembly is fixed to the upper end of the box assembly;

[0015] The upper air inlet pipe is equipped with an upper air inlet electrically controlled valve, the lower air inlet pipe is equipped with a lower air inlet electrically controlled valve, the upper air outlet pipe is equipped with an upper air outlet electrically controlled valve, and the lower air outlet pipe is equipped with a lower air outlet electrically controlled valve.

[0016] Compared with the existing technology, the present invention adopts an intelligent positive and negative pressure differential balance design on the upper and lower parts of the car, which effectively prevents the polluted gas inside the shaft from being squeezed out of the shaft during operation, thereby avoiding polluting the indoor air environment of the home; as the car rises and falls, the air can be purified through the circulating air purification mechanism, which can fully ensure the air quality in the elevator shaft

[0017] Preferably, the elevator electric control system includes a control system; the control system is connected to the circulating air purification mechanism, and a positive and negative pressure control module is provided in the control system;

[0018] The positive and negative pressure control module is connected to the upper air inlet electric control valve, the lower air inlet electric control valve, the upper air outlet electric control valve and the lower air outlet electric control valve.

[0019] Furthermore, the lifting and lowering of the box assembly can be controlled to accurately control the opening and closing of the upper air inlet electric control valve, the lower air inlet electric control valve, the upper air outlet electric control valve and the lower air outlet electric control valve. When the box assembly is lifted or lowered, the gas above and below the box assembly will be facilitated to flow, and the positive and negative pressure control module can sense the changes in the air pressure above and below the box assembly, that is, when the box assembly rises, the positive and negative pressure control module located at the upper end of the box assembly detects an increase in air pressure, and the positive and negative pressure control module located at the lower end of the box assembly detects a decrease in air pressure; at this time, the upper air inlet assembly and the lower air outlet pipe fitting of the car are unobstructed, while the lower air inlet pipe fitting and the upper air outlet assembly of the car are closed; conversely, when the box assembly descends, the positive and negative pressure control module located at the upper end of the box assembly detects a decrease in air pressure, and the positive and negative pressure control module located at the lower end of the box assembly detects an increase in gas. At this time, the lower air inlet pipe fitting and the upper air outlet assembly of the car are unobstructed, and the upper air inlet assembly and the lower air outlet pipe fitting of the car are closed.

[0020] Preferably, the circulating air purification mechanism includes a sealing plate, a filter purification component and a circulating purification housing, wherein the circulating purification housing is provided with an air inlet chamber, a purification chamber and an air outlet chamber from front to back, and both ends of the purification chamber are connected to the air inlet chamber and the air outlet chamber, the filter purification component is sealed in the purification chamber, and the sealing plate and the circulating purification housing are detachably connected;

[0021] The upper air inlet pipe and the lower air inlet pipe both penetrate and extend into the air inlet cavity, and the upper air outlet pipe and the lower air outlet pipe both penetrate and extend into the air outlet cavity.

[0022] Furthermore, in actual production, corresponding control purification components or activated carbon particles are placed in the filter purification assembly. According to the distance between the filter purification assembly and the air inlet cavity, the activated carbon particles are gradually reduced from near to far. Moreover, the filter purification assembly can be quickly replaced by removing the sealing plate to ensure the adsorption effect of impurities in the air. In addition, the air from the lower air inlet pipe and the upper air inlet pipe enters the air inlet cavity to increase the air pressure in the air inlet cavity, so that the gas moves toward the air outlet cavity through the filter purification assembly to be discharged through the lower air outlet pipe and the upper air outlet pipe.

[0023] At the same time, two circulating air purification mechanisms can be provided, so that one circulating air purification mechanism is connected to the upper air inlet pipe and the lower air outlet pipe, and the other circulating air purification mechanism is connected to the lower air inlet pipe and the upper air outlet pipe.

[0024] Preferably, the lifting mechanism includes an elevator shaft, and slide rails are slidably installed on both sides and both sides of the rear end of the box assembly; the slide rails are fixed in the elevator shaft, a damping and shock-absorbing assembly is installed at the bottom of the elevator shaft, and a drive assembly is installed at the top of the elevator shaft, and the drive assembly is connected to the elevator electronic control system.

[0025] Furthermore, through the operation of the driving assembly and the control system, the box assembly can be raised and lowered, and the stability of the lifting can be ensured by the slide rail, and the damping and shock-absorbing assembly can help improve the safety of use.

[0026] Preferably, the control system is connected to a wireless control module and an air quality detection module; the wireless control module is connected to the lifting mechanism.

[0027] Furthermore, the lifting and lowering of the box assembly can be controlled.

[0028] Preferably, the air quality detection module is installed in the elevator shaft.

[0029] Furthermore, the gas quality in the elevator shaft can be accurately understood, and the air quality detection module will be connected to the control system so that after detecting that the gas quality in the elevator shaft has decreased, the control system can automatically control the operation of the drive component to make the box component rise and fall.

[0030] The present invention also proposes a purification method for an elevator with a positive and negative pressure balanced hoistway internal circulation polluted air treatment and purification device, which is applicable to the above-mentioned elevator with a positive and negative pressure balanced hoistway internal circulation polluted air treatment and purification device, and includes the following steps:

[0031] S1. Elevator start: Through the control button and wireless control module, the driving component can drive the box component to move up and down along the slide rail, and can move to the corresponding floor as needed;

[0032] S2. Generation of positive and negative pressure environments in the elevator shaft: When the box assembly moves upward, the space above it shrinks, the air is squeezed, and the air pressure above the box assembly increases. At the same time, the space below the box assembly increases, causing the air pressure below the box assembly to decrease.

[0033] When the box assembly moves downward, the space below the box assembly shrinks and the air is squeezed, causing the air pressure below the box assembly to increase. At this time, the space above the box assembly increases, causing the air pressure above the box assembly to decrease.

[0034] When the box assembly is in motion, the air pressure above and below it will change. When the box assembly stops moving, the air will flow through the gap between the box assembly and the elevator shaft, making the air pressure above and below the box assembly equal;

[0035] S3, gas purification: When the box assembly rises, the upper air inlet electric control valve and the lower air outlet electric control valve are opened, and the lower air inlet electric control valve and the upper air outlet electric control valve are closed, so that the air at the upper end of the box assembly can enter the circulating air purification mechanism through the upper air inlet assembly of the car and the upper air inlet pipe, and enter the filter purification assembly through the air inlet cavity. The purified air enters the lower air outlet pipe through the air outlet cavity, so that the purified air can enter the lower end of the box assembly;

[0036] When the box assembly descends, the lower air inlet electric control valve and the upper air outlet electric control valve are opened, and the upper air inlet electric control valve and the lower air outlet electric control valve are closed, so that the air at the lower end of the box assembly can enter the circulating air purification mechanism through the lower air inlet pipe and enter the filter purification assembly through the air inlet cavity. The purified air can enter the upper air outlet pipe through the air outlet cavity and be discharged to the upper end of the box assembly through the upper air outlet assembly of the car. This fully makes the air at the upper and lower ends of the box assembly uniform and can purify the air in the elevator shaft.

[0037] S4. Automatic operation during idle time: During idle time, the box assembly can be controlled to rise and fall automatically through the wireless control module to treat the air in the stairwell;

[0038] S5. Gas flow at rest: When the box assembly stops operating, the electrically controlled valve assembly and the circulating air purification mechanism installed thereon are both in an open state, facilitating gas flow and ensuring that the upper and lower portions of the box assembly are in an isobaric state.

[0039] The beneficial effects of the present invention are:

[0040] 1. In this application, since the air duct is arranged at the upper and lower parts of the car, it starts from the bottom of the hoistway and ends at the top of the hoistway with the car, and the polluted air in the hoistway can be purified to the greatest extent;

[0041] 2. In this application, the upper and lower parts of the car adopt an intelligent positive and negative pressure differential balance design, which effectively prevents the polluted gas inside the shaft from being squeezed out of the shaft during operation, thereby avoiding polluting the indoor air environment of the home;

[0042] 3. By setting up a wireless control module, the car can be remotely controlled to move up and down, and the shaft air can be purified through a circulating air purification device, which improves the intelligence and automation level of the device and facilitates user operation and use.

[0058] During actual operation, the control system can control the lifting and lowering of the box assembly 1, and can control the operation of the two circulating air purification mechanism 6 fans through the lifting and lowering of the box assembly 1, that is, when the box assembly 1 rises, the fan connected to the lower air outlet pipe 5 can be operated to quickly extract gas, and the other fan stops operating, so that the upper air inlet pipe 10 and the upper air inlet assembly 8 of the car can quickly extract the gas from the upper end of the box assembly 1, which can facilitate the gas at the upper end of the box assembly 1 to purify the circulating air purification mechanism 6, so that the gas at the lower end of the box assembly 1 is clean;

[0059] On the contrary, when the box assembly 1 is lowered, the fan connected to the upper air outlet pipe 14 can be operated, and the other fan stops operating, so that the air at the lower end of the box assembly 1 can be extracted and the purified air can be discharged to the upper end of the box assembly 1;

[0060] Moreover, during actual production and preparation, the operation of the fan can be connected to the elevator control equipment, and automation components can be set up so that after a long period of shutdown, the box components can be automatically operated and purification operations can be carried out.

As the gas flows, the air pressure in the air intake cavity 631 increases, and at the same time, the air pressure in the air outlet cavity 633 decreases, so that the air pressure passes through the air intake cavity 631 and the filtering and purification assembly 62 and enters the air outlet cavity 633.

[0078] Example 3

[0079] The present invention also proposes a purification method for an elevator with a positive and negative pressure balanced hoistway internal circulation polluted air treatment and purification device, which is applicable to the above-mentioned elevator with a positive and negative pressure balanced hoistway internal circulation polluted air treatment and purification device, and includes the following steps:

[0080] S1. Elevator start: The control button and the wireless control module can be used to enable the driving assembly 17 to drive the box assembly 1 to move up and down along the slide rail 15, and can move to the corresponding floor as needed;

[0081] S2. Generation of positive and negative pressure environment in the elevator shaft: When the box assembly 1 moves upward, the space above it shrinks, the air is squeezed, and the air pressure above the box assembly 1 increases. At the same time, the space below the box assembly 1 increases, causing the air pressure below the box assembly 1 to decrease.

[0082] When the box assembly 1 moves downward, the space below the box assembly 1 shrinks and the air is squeezed, causing the air pressure below the box assembly 1 to increase. At this time, the space above the box assembly 1 increases, causing the air pressure above the box assembly 1 to decrease.

[0083] When the box assembly 1 is in motion, the air pressure above and below it will change. When the box assembly 1 stops moving, the air will flow through the gap between the box assembly 1 and the elevator shaft, making the air pressure above and below the box assembly 1 balanced.

[0084] S3, gas purification: When the box assembly 1 rises, the upper air inlet electric control valve 11 and the lower air outlet electric control valve 12 are opened, and the lower air inlet electric control valve 9 and the upper air outlet electric control valve 13 are closed, so that the air at the upper end of the box assembly 1 can enter the circulating air purification mechanism 6 through the upper air inlet assembly 8 of the car and the upper air inlet pipe 10, and enter the filter purification assembly 62 through the air inlet cavity 631. The purified air enters the lower air outlet pipe 5 through the air outlet cavity 633, so that the purified air can enter the lower end of the box assembly 1;

[0085] When the box assembly 1 descends, the lower air inlet electric control valve 9 and the upper air outlet electric control valve 13 are opened, and the upper air inlet electric control valve 11 and the lower air outlet electric control valve 12 are closed, so that the air at the lower end of the box assembly 1 can enter the circulating air purification mechanism 6 through the lower air inlet pipe 4, and enter the filter purification assembly 62 through the air inlet cavity 631. The purified air can enter the upper air outlet pipe 14 through the air outlet cavity 633, and be discharged to the upper end of the box assembly 1 through the upper air outlet assembly 7 of the car; the gas at the upper and lower ends of the box assembly 1 is fully uniform, and the air in the elevator shaft can be purified;

[0086] S4, automatic operation during idle time: During the idle time period, the box assembly 1 can be controlled to rise and fall automatically through the wireless control module to process the air in the stairwell;

[0087] S5. Gas flow at rest: When the box assembly 1 stops operating, the electrically controlled valve assembly and the circulating air purification mechanism 6 installed thereon are both in an open state, facilitating gas flow and ensuring that the upper and lower portions of the box assembly 1 are in an isobaric state.

[0088] In the present invention, the control button and the wireless control module can be used to enable the driving component 17 to drive the box component 1 to move up and down along the slide rail 15. The position of the box component 1 can be adjusted by the control button. When not in use, the box component 1 can be regularly controlled to move up and down by the wireless control module.

[0089] When the box assembly 1 moves upward, the space above it shrinks, and the air is squeezed, causing the air pressure above the box assembly 1 to increase. At this time, the space below the box assembly 1 increases, causing the air pressure below the box assembly 1 to decrease. When the box assembly 1 moves downward, the space below the box assembly 1 shrinks and the air is squeezed, causing the air pressure below the box assembly 1 to increase. At this time, the space above the box assembly 1 increases, causing the air pressure above the box assembly 1 to decrease. When the box assembly 1 is in operation, the air pressure above and below it will change. When the box assembly 1 stops moving, the air will flow through the gap between the box assembly 1 and the elevator shaft, making the air pressure above and below the box assembly 1 balanced.

[0090] When the box assembly 1 rises, the upper air inlet electric control valve 11 and the lower air outlet electric control valve 12 are opened, and the lower air inlet electric control valve 9 and the upper air outlet electric control valve 13 are closed, so that the air at the upper end of the box assembly 1 can enter the circulating air purification mechanism 6 through the upper air inlet assembly 8 of the car and the upper air inlet pipe 10, and enter the filter purification assembly 62 through the air inlet cavity 631. The purified air enters the lower air outlet pipe 5 through the air outlet cavity 633, so that the purified air can enter the lower end of the box assembly 1; when the box assembly 1 descends, the lower air inlet electric control valve 9 and The upper air outlet electric control valve 13 is opened, and the upper air inlet electric control valve 11 and the lower air outlet electric control valve 12 are closed, so that the air at the lower end of the box assembly 1 can enter the circulating air purification mechanism 6 through the lower air inlet pipe 4, and enter the filtering and purification assembly 62 through the air inlet cavity 631. The purified air can enter the upper air outlet pipe 14 through the air outlet cavity 633, and be discharged to the upper end of the box assembly 1 through the upper air outlet assembly 7 of the car; the gas at the upper and lower ends of the box assembly 1 is fully uniform, and the cavity in the elevator shaft 18 can be purified by raising and lowering the box assembly 1.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
