Description

Technical Field

[0001] The invention relates to the field of biological deodorization, and in particular to an automatic sludge cleaning device. Background Art

[0002] As garbage classification becomes more and more popular, wet garbage treatment is becoming more and more important. A large amount of odor will be released during wet garbage treatment. In order to avoid environmental pollution, the odor needs to be collected and centrally treated before being discharged. In the odor treatment process, biological deodorization is widely used due to its low operating cost and simple operation and maintenance.

[0003] However, since wet garbage releases a lot of odor and organic matter, it is easy to be absorbed and decomposed by domesticated bacteria, resulting in rapid growth of biological bacteria in the biological tower and a large amount of biofilm. Due to the spraying effect at the top of the biological tower, the biofilm will continue to fall off and deposit at the bottom of the tower. The biofilm has a certain degree of adhesion and cannot be effectively discharged by drainage, resulting in a large amount of sediment at the bottom of the biological tower. The sediment ferments at the bottom of the biological tower and also releases odor, which has a counter-effect on the treatment effect of the system. Therefore, it is necessary to regularly and effectively remove the sediment at the bottom of the biological tower to ensure the biological deodorization effect.

[0004] In the existing related technologies, it is generally necessary to shut down the equipment and manually clean the sludge at the bottom of the tower. However, manual work at the bottom of the tower is a confined space operation, and there are a large number of toxic and harmful gases in the tower, which are very harmful to human health. Therefore, there is an urgent need for an automatic sludge cleaning device that can reduce manual intervention, thereby reducing the harm to human life while ensuring that the sludge cleaning effect meets the standards.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] Combination Figure 1 and Figure 3 As shown, an automatic sludge cleaning device is provided, which can automatically clean the bottom sludge of the cleaning equipment 100. In this embodiment, the automatic sludge cleaning device is used to automatically clean the bottom sludge accumulated at the bottom of the biological tower.

[0032] Specifically, refer to Figure 1 As shown, the automatic sludge cleaning device includes an absorption mother pipe 1, a sliding drive assembly 2 and a negative pressure drive member 3. Among them, the absorption mother pipe 1 is located in the equipment to be cleaned 100, and a row of multiple negative pressure suction holes 11 are opened on the side of the absorption mother pipe 1 facing the bottom of the biological tower. The number of negative pressure suction holes 11 is not limited. The negative pressure suction holes 11 are connected to the negative pressure drive member 3 through the internal space of the absorption mother pipe 1, so that after the negative pressure drive member 3 is started, the absorption mother pipe 1 can absorb the sludge at the bottom of the biological tower through the negative pressure suction holes 11. The sliding drive assembly 2 is installed on the biological tower, and the sliding drive assembly 2 is transmission-connected to the absorption mother pipe 1, so that the absorption mother pipe 1 can move along a preset direction. In this embodiment, it is set Figure 1 The central X-axis (parallel to the length direction of the biological tower) is a preset direction, so that the absorption main pipe 1 can absorb and clean the sludge at the bottom of the biological tower along the length direction of the biological tower.

[0033] The use of the automatic sludge cleaning device provided in this embodiment can not only effectively prevent the sludge from settling and fermenting in the biological tower, releasing foul-smelling gases, affecting the effective operation of the deodorization system, and preventing the discharged pollutants from polluting the environment; it can also avoid manual cleaning of the sludge at the bottom of the biological tower, thereby reducing the process of manual intervention, reducing the harm to human health, and ensuring that the sludge cleaning effect reaches the preset standard, thereby greatly enhancing the practicality of the automatic sludge cleaning device.

[0034] The absorption main pipe 1 is spaced apart from the bottom of the biological tower. For example, in this embodiment, the absorption main pipe 1 is 10 mm away from the bottom of the biological tower, which can not only reduce the friction of the absorption main pipe 1, reduce wear and tear, and extend the service life, but also help to improve the distribution of airflow, thereby further improving the sludge absorption effect.

[0035] A sliding drive assembly 2 is provided at each end of the absorption main pipe 1, so as to ensure that the absorption main pipe 1 maintains balance during movement and avoids the situation where the absorption main pipe 1 is skewed and affects the sludge absorption effect.

[0036] Optionally, the automatic sludge cleaning device provided in this embodiment further includes a shunt pipe 4, which is in a "Y" shape and includes a main pipe 41 and two shunt branches 42, wherein one end of the main pipe 41 is connected to the negative pressure driving member 3, and the other end of the shunt pipe 4 is simultaneously connected to the two shunt branches 42, and the two shunt branches 42 are connected along the Figure 1 The Y axis (parallel to the width direction of the biological tower) is arranged at intervals. In addition, there are two absorption main pipes 1, which are connected to the branch pipes 42 one by one. Through the two parallel absorption main pipes 1, the bottom of the biological tower can be divided into two areas for sludge absorption, so that segmented cleaning can be achieved, which helps to improve the cleaning efficiency and effect.

[0037] A sliding drive assembly 2 is installed at both ends of each absorption mother tube 1 to ensure that each absorption mother tube 1 has a stable working state. In this embodiment, it is set that the sliding drive assemblies 2 on different absorption mother tubes 1 can be opened in sequence, that is, when the two sliding drive assemblies 2 on the first absorption mother tube 1 are opened, the first absorption mother tube 1 can move forward along the X-axis direction at this time to absorb the sludge at the bottom of the biological tower, and then move backward along the X-axis direction and reset, and reciprocate in sequence until the sludge at the bottom of the biological tower in the first area is observed to be cleaned up. Then, the two sliding drive assemblies 2 on the first absorption mother tube 1 are closed, and the two sliding drive assemblies 2 on the second absorption mother tube 1 are opened, so that the second absorption mother tube 1 can reciprocate along the X-axis direction until the sludge at the bottom of the biological tower in the second area is observed to be cleaned up.

[0038] By making each absorption main pipe 1 work independently, it can be ensured that after the sludge in the previous area is cleaned, it can switch to the next area to continue cleaning. At the same time, the cleaning effect of the previous area can be maintained without being disturbed, thereby effectively improving the efficiency of sludge cleaning and ensuring that the sludge at the bottom of the biological tower can be thoroughly absorbed.

[0039] The present invention does not limit the number of absorption mother tubes 1. It is understandable that in other parallel embodiments, more than two absorption mother tubes 1 can be provided to accommodate a larger width of the equipment 100 to be cleaned. At this time, more than two branch pipes 42 can be provided to correspond to the number of absorption mother tubes 1. Therefore, those skilled in the art can divide the equipment 100 to be cleaned into different numbers of areas according to the specific specifications, thereby using different numbers of absorption mother tubes 1 to achieve the required cleaning standards.

[0040] Furthermore, the automatic sludge cleaning device provided in this embodiment also includes a controller and two electromagnetic switch valves 5, and each of the two branch pipes 42 is provided with an electromagnetic switch valve 5; the controller is communicatively connected to the two electromagnetic switch valves 5 and the two sliding drive members 23 on each absorption mother pipe 1. When in use, the controller can first open the sliding drive components 2 at both ends of the first absorption mother pipe 1, and the electromagnetic switch valves 5 on the branch pipe 42 connected to the first absorption mother pipe 1, so that the first absorption mother pipe 1 reciprocates along the X axis, and the negative pressure drive member 3 (specifically using a water pump) can first suck the sludge from the first area. After the first absorption mother pipe 1 absorbs the sludge in the first area, and when the controller detects that the cleanliness in the first area meets the standard, the controller can simultaneously close the sliding drive components 2 at both ends of the first absorption mother pipe 1 and the electromagnetic switch valve 5 on the branch pipe 42 connected to the first absorption mother pipe 1, so that the first absorption mother pipe 1 is reset and remains in a static state; then the controller simultaneously opens the sliding drive components 2 at both ends of the second absorption mother pipe 1 and the electromagnetic switch valve 5 on the branch pipe 42 connected to the second absorption mother pipe 1, so that the second absorption mother pipe 1 reciprocates along the X axis, and the negative pressure drive component 3 can continue to absorb the sludge from the second area. In this way, the working process of the above-mentioned two absorption mother pipes 1 independently and automatically absorbing sludge is completed, with high control accuracy and can ensure a good sludge absorption effect.

[0041] Optionally, the automatic sludge cleaning device provided in this embodiment also includes a flow hose 6, and both ends of the flow hose 6 are respectively connected to the absorption main pipe 1 and the branch pipe 42 corresponding to the absorption main pipe 1. The flow hose 6 can ensure that the absorption main pipe 1 can move forward and backward along the X-axis. Moreover, since the flow hose 6 is often made of other flexible materials such as rubber and silicone, it has a certain shock absorption and impact resistance effect, which can reduce the possibility of the flow hose 6 causing impact to the absorption main pipe 1 during the movement of the absorption main pipe 1, thereby reducing the damage to the absorption main pipe 1 and helping to extend the service life of the absorption main pipe 1.

[0042] It should be noted that the structures of the sliding drive components 2 installed on different absorbent mother tubes 1 provided in this embodiment are the same, so the structure of one of the sliding drive components 2 is specifically described below by taking it as an example.

[0043] Specifically, refer to Figure 2As shown, the sliding drive assembly 2 includes a directional slide rail 21, a transmission member 22 and a sliding drive member 23. The directional slide rail 21 is extended along the X-axis, and both ends of the directional slide rail 21 are fixedly connected to the biological tower; the transmission member 22 is movably arranged on the directional slide rail 21 along the X-axis direction, the transmission member 22 is connected to the absorption mother pipe 1, and the sliding drive member 23 is transmission-connected to the transmission member 22. Through the above arrangement, not only the structure of the sliding drive assembly 2 is simple and easy to use, but also the directional slide rail 21 can ensure that the transmission member 22 can move stably with the absorption mother pipe 1 along the X-axis direction to avoid deflection, thereby ensuring that the absorption mother pipe 1 has a stable and reliable mud suction capacity.

[0044] Furthermore, a slideway 211 is opened in the directional slide rail 21 along the X-axis direction, and the transmission member 22 can be movably arranged in the slideway 211 to wrap the transmission member 22 through the slideway 211, so as to ensure that the transmission member 22 will not derail when moving, thereby further improving the stability and reliability of mud suction of the absorption mother pipe 1.

[0045] Furthermore, a side wall surface of the directional slide rail 21 is provided with an avoidance channel 212, which extends in a preset direction and is connected to the slideway 211. In addition, the transmission member 22 is a transmission gear, and the end face and side face of the transmission gear are both fitted and connected to the inner wall surface of the slideway 211 to ensure that the transmission member 22 can effectively operate in the slideway 211 to prevent slipping. The sliding drive member 23 adopts a waterproof motor. After the transmission shaft of the sliding drive member 23 passes through the avoidance channel 212, it is connected to the transmission gear through a rotating bearing. The fixed end of the sliding drive member 23 is fixedly connected to the absorption mother pipe 1, and the sliding drive member 23 is communicatively connected to the above-mentioned controller.

[0046] Through the above-mentioned setting, when the controller controls the sliding drive member 23 to start, the sliding drive member 23 can control the transmission gear to rotate in the slideway 211, and then through the rotation of the transmission gear, the transmission gear can drive the sliding drive member 23 and the absorption mother pipe 1 connected to the fixed end of the sliding drive member 23 to move, and the setting of the sliding drive member 23 and the transmission gear can realize precise control of the moving position of the absorption mother pipe 1, so that the absorption mother pipe 1 can move with high precision on the positioning slide rail, thereby enhancing the controllability of the controller over the movement position of the absorption mother pipe 1, thereby improving the cleaning performance of the entire sludge automatic cleaning device.

[0047] It should be noted that the rotating bearing also adopts a waterproof bearing, and the directional slide rail 21 and the above-mentioned absorption mother pipe 1 are both made of corrosion-resistant materials to ensure the service life.

[0048] Specifically, in this embodiment, combined with Figure 2 , Figure 3As shown, the transmission gear includes a main transmission gear 221 and a slave transmission gear 222 that are meshed and connected. The main transmission gear 221 is connected to the transmission shaft of the sliding drive member 23 through a rotating bearing, and the end faces and side faces of the main transmission gear 221 and the slave transmission gear 222 are both fitted and connected to the inner wall surface of the slideway 211, thereby ensuring that the main transmission gear 221 and the slave transmission gear 222 are stably meshed, so that the absorption mother tube 1 can achieve reciprocating movement through the relative rotation of the two, thereby further improving the transmission efficiency of the sliding drive member 23, improving the movement performance of the entire sliding drive assembly 2, and avoiding slipping, derailment, etc. when the main transmission gear 221 and the slave transmission gear 222 rotate, further improving the safety of the movement process of the absorption mother tube 1.
