Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment lifting device made of stainless steel. Background Art

[0002] After forging, stainless steel castings have a very high temperature, so they must be cooled before entering the next processing step. The current cooling method is to use cold water to cool the stainless steel castings. The sewage generated after cooling, if not treated, is directly discharged, which is easy to cause serious pollution to the natural environment. Therefore, it is usually necessary to use a sewage treatment lifting device to transport the sewage to other locations for storage, and then treat it uniformly. In industrial production, a lifting pump is generally used as a sewage treatment lifting device to transport the sewage to the inside of the sewage treatment device.

[0003] However, the currently cooled sewage contains a large amount of metal fragments. If it is directly transported to the sewage treatment device, it is easy to cause the sewage treatment lifting device to be blocked. Moreover, these metal fragments still have value for recycling. The existing sewage treatment lifting device cannot collect the metal fragments. Due to the high heat of the sewage, directly using the sewage treatment lifting device to transport the sewage may cause high-temperature damage to the internal parts of the sewage treatment lifting device. Therefore, in view of the above problems, a sewage treatment lifting device made of stainless steel is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a sewage treatment lifting device made of stainless steel to solve the problems raised in the above background technology.

[0007] Preferably, a horizontally arranged condensing coil is provided between the first snap-fit ​​cover and the second snap-fit ​​cover, a sealing sleeve tightly fitting with the inner sides of the first snap-fit ​​cover and the second snap-fit ​​cover is fixedly connected to the outer side of the condensing coil, a retaining ring fixedly connected to the condensing coil is fixedly connected to one side of the sealing sleeve, a horizontally arranged fixed box is provided on the outer side of the condensing coil, and a cooling fan vertically arranged and passing through the fixed box is fixedly connected to one side of the fixed box.

[0008] Preferably, one end of the condensing coil away from the first locking cover is fixedly connected to the lifting pump and is connected to the lifting pump, and the number of the cooling fans is six.

[0009] Preferably, the first snap-fit ​​cover and the second snap-fit ​​cover are of the same shape and size, the number of the fixing plate, the round hole, the bolts and the nuts are all four, and the fixing plate located at the bottom is fixedly connected to the second snap-fit ​​cover.

[0010] Preferably, the inner diameter of the circular hole is larger than the outer diameter of the bolt, the number of the filter plates is four, and the aperture sizes of the filter plates are arranged to increase in sequence from left to right.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, by providing the first snap-fit ​​cover, the fixing plate, the circular hole, the bolt, the nut, the observation window, the second snap-fit ​​cover and the filter plate, it is not only possible to prevent metal fragments from clogging the sewage treatment lifting device, but also possible to observe the collection of metal fragments, so as to clean the metal fragments in time. First, the first snap-fit ​​cover and the second snap-fit ​​cover are installed to the end of the condensing coil away from the lifting pump, and the retaining ring and the sealing sleeve are directly placed on the inner side of the second snap-fit ​​cover. Then, the fixing plate on the first snap-fit ​​cover is aligned with the fixing plate on the second snap-fit ​​cover, the bolt is inserted into the inner side of the circular hole, and the nut is screwed on the outer side of the bolt. At this time, the sealing sleeve, the first snap-fit ​​cover and the second snap-fit ​​cover are fixed to the inner side of the circular hole, and the nut is screwed on the outer side of the bolt. The cover and the second snap-fit ​​cover fit tightly together, and the installation of the first snap-fit ​​cover and the second snap-fit ​​cover can be completed. When the device needs to be used, the ends of the first snap-fit ​​cover and the second snap-fit ​​cover away from the condensing coil are connected to the sewage, and the end of the lifting pipe away from the lifting pump is connected to the inner side of the sewage treatment device. The device is powered on, and the lifting pump is started. The lifting pump pumps the sewage into the inner side of the sewage treatment device. The filter plates with different apertures filter the metal fragments into the inner sides of the first snap-fit ​​cover and the second snap-fit ​​cover. The collection of the metal fragments can be observed through the observation window. After the metal fragments are fully collected, the first snap-fit ​​cover and the second snap-fit ​​cover can be removed for cleaning;

[0013] 2. In the utility model, the sewage can be cooled by the condensing coil, the fixed box and the cooling fan to prevent the lifting pump from being damaged by excessive temperature. When the equipment is in use, the cooling fan is started and the sewage passes through the condensing coil. The design of the condensing coil increases the heat dissipation area of ​​the sewage. The cooling fan takes away the heat of the sewage, thereby reducing the temperature of the sewage. BRIEF DESCRIPTION OF THE DRAWINGS
