Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, and more specifically, to a wastewater treatment pool. Background Art

[0002] A wastewater treatment pool is a pool used to filter, settle, and purify wastewater so that it meets recycling standards. In the water circulation system, wastewater treatment pools are of certain importance. The structure of wastewater treatment pools varies depending on factors such as the type of wastewater, the amount of wastewater, and the corresponding wastewater treatment methods.

[0003] Existing wastewater treatment tanks generally allow water to flow linearly in a single direction, so that the wastewater is filtered, settled, or otherwise treated along its flow. However, for some indoor pools, they are limited by the size of the plant, and linear pools require a larger depth of space.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wastewater treatment pool.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a wastewater treatment tank, comprising an inner tank body and an outer tank body, the inner tank body being located in the outer tank body, one side wall of the inner tank body being in contact with one side wall of the outer tank body, a C-shaped cavity being provided between the outer side wall of the inner tank body and the inner side wall of the outer tank body, an overflow port being provided at the top end of the side wall of the inner tank body, one end of the C-shaped cavity being connected to the inner cavity of the inner tank body through the overflow port, the other end of the C-shaped cavity being fixedly connected to an outlet channel, the top end of the side wall of the inner tank body being fixedly connected to an inlet channel, and a filter plate being provided between the inlet channel and the overflow port.

[0007] The utility model is further configured as follows: the filter plate is embedded in the top end of the inner tank body, the top surface of the filter plate is lower than the lowest point of the water inlet flow channel, and the bottom surface of the filter plate is higher than the bottom surface of the overflow port.

[0008] The utility model is further configured as follows: one end of the filter plate away from the water inlet channel is fixedly connected with a baffle, and the top surface of the baffle is higher than the top surface of the inner tank body.

[0009] The present invention is further configured as follows: the water inlet flow channel spans over the top of the C-shaped groove, and the water inlet flow channel and the overflow port are respectively located at two ends of the inner groove body.

[0010] The present invention is further configured as follows: a pad is integrally formed on the inner wall of the water inlet channel, and the inner diameter of the pad is smaller than the inner diameter of the water inlet channel.

[0011] The utility model is further configured as follows: a ridge is fixedly connected to the bottom surface of the outer trough body, the two ends of the ridge are respectively fixedly connected to the outer side wall of the inner trough body and the inner side wall of the outer trough body, and the ridge and the overflow port are respectively located on both sides of the inner trough body.

[0012] The utility model is further configured such that adjacent side walls of the C-shaped cavity are all transitioned by circular arcs.

[0013] In summary, the utility model has the following beneficial effects: the filter plate intercepts larger debris in the wastewater during the falling process of the wastewater, exchanges the vertical height for the horizontal length, shortens the length of the wastewater treatment pool, and the C-shaped cavity surrounds the inner tank body in a semi-enclosed form, making the structure of the wastewater treatment pool more compact, further shortening the length of the wastewater treatment pool, and at the same time the zigzag forward method slows down the flow rate of the wastewater, and the sediment carried by the wastewater is deposited in the C-shaped cavity.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] Example: A wastewater treatment pool, such as Figure 1 As shown, it includes an inner tank body 1 and an outer tank body 2, the inner tank body 1 is located in the outer tank body 2, and one side wall of the inner tank body 1 fits into a side wall of the outer tank body 2. A C-shaped cavity 3 is provided between the outer wall of the inner tank body 1 and the inner wall of the outer tank body 2, and an overflow port 4 is provided at the top end of the side wall of the inner tank body 1. One end of the C-shaped cavity 3 is communicated with the inner cavity of the inner tank body 1 through the overflow port 4, and the other end of the C-shaped cavity 3 is fixedly connected with a water outlet channel 5, and the top end of the side wall of the inner tank body 1 is fixedly connected with a water inlet channel 6. A filter plate is provided between the water inlet channel 6 and the overflow port 4, and the filter plate is embedded in the top end of the inner tank body 1. The top surface of the filter plate is lower than the lowest point of the water inlet channel 6, and the bottom surface of the filter plate is higher than the bottom surface of the overflow port 4. The end of the filter plate away from the water inlet channel 6 is fixedly connected with a baffle 7, and the top surface of the baffle 7 is higher than the top surface of the inner tank body 1. The adjacent side walls of the C-shaped cavity 3 are all arc transitions.

[0018] Specifically, the bottom surface of the inner trough body 1 and the bottom surface of the outer trough body 2 coincide with each other, the water inlet channel 6 is connected to the water inlet pipe, the water outlet channel 5 is connected to the water outlet pipe, the bottom surface of the overflow port 4 is higher than the lowest point of the water outlet channel 5, and a number of filter holes are provided on the filter plate. Slide rods are integrally formed on both sides of the filter plate, and the baffle 7 is integrally formed with the filter plate. The slide rod and the baffle 7 are perpendicular to the filter plate, and the top surface of the slide rod is flush with the top surface of the baffle 7. Four slide grooves are provided on the top of the inner side wall of the inner trough body 1, and the slide rod and the top plate are slidably connected in the slide grooves. When the filter plate needs to be cleaned, the slide rod and the baffle 7 are pulled up to pull the filter plate out for cleaning. The water flows along the water inlet channel 6 and falls onto the filter plate. The filter plate intercepts larger debris in the wastewater during the falling process, and the vertical height is exchanged for the horizontal length, shortening the vertical height. The length of the wastewater treatment tank is shortened. The debris retained on the filter plate moves toward the baffle 7 under the impact of subsequent water flow, preventing the debris from blocking the end of the water inlet channel 6, and the debris is finally intercepted by the baffle 7. The filter plate is higher than the overflow port 4, preventing the debris from continuing to float on the water surface, making it easier to collect and clean the debris. The wastewater passing through the filter plate accumulates in the inner tank body 1. As the water level rises, the wastewater exceeding the bottom of the overflow port 4 flows into the C-shaped cavity 3. The C-shaped cavity 3 surrounds the inner tank body 1 in a semi-enclosed form, making the structure of the wastewater treatment tank more compact and further shortening the length of the wastewater treatment tank. At the same time, the tortuous forward movement slows down the flow rate of the wastewater, and the sediment carried by the wastewater is deposited in the C-shaped cavity 3. The arc corner of the C-shaped cavity 3 avoids the formation of cleaning dead corners, making it convenient for dredging equipment to clean the sediment.

[0019] like Figure 1 As shown, the water inlet channel 6 spans above the C-shaped groove, and the water inlet channel 6 and the overflow port 4 are respectively located at the two ends of the inner tank body 1. A pad 8 is integrally formed on the inner wall of the water inlet channel 6, and the inner diameter of the pad 8 is smaller than the inner diameter of the water inlet channel 6. A ridge 9 is fixedly connected to the bottom surface of the outer tank body 2, and the two ends of the ridge 9 are respectively fixedly connected to the outer wall of the inner tank body 1 and the inner wall of the outer tank body 2. The ridge 9 and the overflow port 4 are respectively located on both sides of the inner tank body 1.

[0020] Specifically, the water inlet channel 6 consists of an arc-shaped channel and two side panels located on the top surface of the arc-shaped channel. The pad 8 is integrally formed with the arc-shaped channel, and the water inlet pipe is placed on the pad 8. The two side panels are used to prevent wastewater splashing. The pad 8 is used to prevent wastewater from flowing back in the water inlet channel 6. The cross-section of the ridge 9 is triangular. The ridge 9 is integrally formed on the bottom surface of the C-shaped cavity 3, and the ridge 9 is located at the end of the C-shaped cavity 3. The ridge 9 prevents sediment from entering the water outlet channel 5. The water inlet channel 6 and the water outlet channel 5 are located on the adjacent two side walls of the outer trough body 2, so that the water inlet pipe and the water outlet pipe are perpendicular to each other.

[0021] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
