Description

Technical Field

[0001] The utility model relates to the field of ventilation, in particular to a ventilation device for a pump station. Background Art

[0002] A pump station is a device that can provide hydraulic and pneumatic power with a certain pressure and flow rate. Specifically, it is used to lift sewage, rainwater, drinking water, and wastewater. It is uniformly manufactured and assembled in the factory and then transported to the site for installation. The pump station is generally divided into two parts, the lower part being the water treatment space and the upper part being the maintenance space, by a maintenance platform. In actual use, personnel are required to enter and perform maintenance regularly for the safety of the pump station. If the treated water is wastewater or sewage, some harmful gases will be generated, making the installation of ventilation devices essential. Existing pump stations usually have vents and exhaust fans on their tops for ventilation. Although this arrangement can achieve ventilation, the ventilation effect is poor, specifically manifested in poor air circulation uniformity. Utility Model Content

[0003] In order to make up for the deficiencies of the prior art, the utility model provides a pump station ventilation device, which inhales air flows in spaces of different heights through the cooperation of multiple sets of ventilation pipes, thereby facilitating more uniform ventilation of the pump station space.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A pump station ventilation device includes multiple groups of ventilation pipes, the lower ends of the multiple groups of ventilation pipes are arranged in a staggered manner to inhale airflow at different heights, the upper ends of the multiple groups of ventilation pipes are connected to a mounting pipe head, the upper part of the mounting pipe head is externally connected to a vertical air duct, the upper side of the vertical air duct is connected to a horizontal air duct, an exhaust fan is provided in the horizontal air duct, so that the airflow inhaled from the ventilation pipe can be discharged after passing through the vertical air duct and the horizontal air duct in sequence, and a filter is also provided at the air outlet of the horizontal air duct.

[0006] Furthermore, ventilation holes are provided at the bottom of each group of ventilation pipes, and the ventilation holes of the multiple groups of ventilation pipes increase in size from high to low.

[0007] Furthermore, the ventilation pipe is threadedly connected to the mounting pipe head.

[0008] Furthermore, the filter element adopts an activated carbon filter.

[0009] Furthermore, a working port is provided at the top of the vertical air duct corresponding to each group of ventilation pipes, and a sealing part is provided in the working port. The sealing part includes a pull rod arranged through the working port, a hand-held part is provided at the upper end of the pull rod, and a sealing plug is provided at the lower end of the pull rod to cooperate with the upper end of the ventilation pipe. A rubber clamping ring that can cooperate with the working port is provided in the middle of the pull rod to suspend the pull rod in the vertical air duct after the sealing plug is moved a certain distance away from the ventilation pipe.

[0010] Furthermore, a first connecting portion is formed on the outer side of the upper end of the vertical air duct which is higher than the horizontal air duct, and is connected to a cover tube.

[0011] Furthermore, the sealing plug is a conical plug.

[0012] Furthermore, the rubber clamping ring is a rubber sleeve that is thick in the middle and thin at both ends.

[0013] Furthermore, the ventilation pipes are arranged into three groups: upper, middle and lower.

[0014] The utility model adopts the above technical solution, which has the advantages that the pump station ventilation device can absorb the airflow in different height spaces in the pump station in layers for ventilation through the arrangement of multiple sets of ventilation pipes, which increases the uniformity of ventilation in the pump station, is conducive to the treatment of harmful gases in the pump station, and thus helps maintenance personnel to carry out maintenance safely.

[0015] By setting up sealing parts, the ventilation time of a certain space layer can be increased according to needs. For example, the bottom of the maintenance space is close to the wastewater and accumulates more harmful gases. Before maintenance, the bottom ventilation can be concentrated to quickly reduce the amount of harmful gases, making it easier for maintenance personnel to carry out maintenance safely.

[0022] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings. In the description of this specification, the reference terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" and the like mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in an appropriate manner.

[0023] like Figures 1-3 As shown, in this embodiment, the pump station ventilation device includes multiple groups of ventilation pipes 1, and the lower ends of the multiple groups of ventilation pipes 1 are arranged in a staggered manner to inhale airflow at different heights. The upper ends of the multiple groups of ventilation pipes 1 are connected to a mounting pipe head 2. The upper part of the mounting pipe head 2 is externally connected to a vertical air duct 3, and the upper side of the vertical air duct 3 is connected to a horizontal air duct 4. An exhaust fan 5 is provided in the horizontal air duct 4 to enable the airflow inhaled from the ventilation pipe 1 to be discharged after passing through the vertical air duct 3 and the horizontal air duct 4 in sequence. A filter 5 is also provided at the air outlet of the horizontal air duct 4.

[0024] The ventilation principle is to install it on the top of the pump station, so that multiple sets of ventilation pipes extend into different spaces at different heights within the pump station. Air inlets are installed at other locations within the pump station. When the exhaust fan is activated, it creates negative pressure, which draws air from spaces at different heights through the multiple sets of ventilation pipes, achieving air purification at different heights and achieving uniform ventilation within the pump station.

[0025] In one specific embodiment, ventilation holes 7 are further provided at the bottom of each set of ventilation pipes, and the ventilation holes of the multiple sets of ventilation pipes 1 are increased in size from high to low. Such an arrangement can ensure the ventilation effect at the bottom and facilitate uniform ventilation of the entire internal space of the pump station.

[0026] In one specific embodiment, the ventilation pipe 1 is threadedly connected to the mounting pipe head 2, which facilitates the disassembly and assembly of the ventilation pipe.

[0027] In one specific embodiment, the filter element 6 can be, but is not limited to, an activated carbon filter to absorb harmful gases.

[0028] In one specific embodiment, the ventilation pipes 1 are preferably arranged into three groups: upper, middle and lower.

[0029] In one embodiment, Figures 4-5 As shown, in order to increase and speed up the ventilation of a certain height space in the pumping station according to needs, the following structural settings can be made: specifically, a working port is provided at the top of the vertical air duct 3 corresponding to each group of ventilation pipes 1, and a sealing member is provided in the working port. The sealing member includes a pull rod 8 arranged through the working port, a hand-held portion 9 is provided at the upper end of the pull rod 8, and a sealing plug 10 is provided at the lower end of the pull rod 8 to cooperate with the upper end of the ventilation pipe 1. The middle part of the pull rod 8 is provided with a rubber clamp 11 that can cooperate with the working port, so that the pull rod can be suspended in the vertical air duct 3 after the sealing plug 10 is away from the ventilation pipe 1 for a distance.

[0030] When it is necessary to start only a certain group of ventilation pipes, the other ventilation pipes 1 can be blocked by the blocking parts. Specifically, the corresponding pull rod 8 can be pressed to make the sealing plug 10 block the ventilation pipe 1, thereby keeping a certain group of ventilation pipes working alone. Selective ventilation can achieve ventilation effect and ventilation speed adjustment, and ventilation applicability is stronger. For example, during non-maintenance periods, multiple groups of ventilation pipes can work at the same time to achieve uniform ventilation; when maintenance is required, the ventilation pipes at that height can be selectively opened according to the nature of the exhaust gas (the height of the space where it stays) to quickly deal with the harmful gases in the space and ensure the safety of maintenance personnel.

[0031] In one specific embodiment, a first connecting portion is formed on the outer side of the upper end of the vertical air duct 3 which is higher than the horizontal air duct 4 and is connected to a cover tube 13 . This arrangement provides better sealing performance.

[0032] In one specific embodiment, the sealing plug 10 is a conical plug for easy sealing.

[0033] In one specific embodiment, the rubber clamping ring 11 is a rubber sleeve that is thick in the middle and thin at both ends, so as to facilitate clamping the pull rod.

[0034] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.

[0035] Anything not described in detail in the present invention is well known to those skilled in the art.
