Description

Technical Field

[0001] The utility model belongs to the technical field of sewage sample treatment, and particularly relates to a sewage inspection sample treatment device. Background Technique

[0002] The treatment of sewage inspection samples mainly involves the following steps: precipitation and filtration, pH value adjustment, dilution, chemical reaction, centrifugal separation and preservation, etc. After the above steps are completed, the samples can be used for various chemical or biological inspections to determine the pollutant content therein or to conduct other relevant analyses. During the treatment of sewage inspection samples, filtering the sewage is an important step;

[0003] In the prior art, generally, the sewage sample is allowed to stand for a period of time so that larger particulate matters and suspended matters settle down, and then, these precipitates and suspended matters are filtered out through a filter to obtain a clearer sample; however, the time required to treat the sewage inspection sample by this method is relatively long, and it is not convenient to operate the separation of the precipitates and suspended matters after standing for a certain period of time, resulting in low work efficiency. Summary of the Utility Model

[0014] The utility model has the following advantages compared with the prior art:

[0015] The structure of the utility model is simple. The main components are the rotating cylinder and the filtering and pumping frame. During the rotation of the rotating cylinder, the sediment and suspended matter adhere to the inner wall edge of the rotating cylinder under the action of centrifugal force.

[0034] In order to enable those skilled in the art to better understand the present utility model, the technical solutions of the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0035] As Figures 1-6 shown, a sewage test sample processing device includes a rotating cylinder 1, a driving mechanism is rotatably connected to the lower part of the rotating cylinder 1, the driving mechanism is assembled and connected to a workbench 2, a filter pumping frame 3 is slidably connected to the inner wall of the rotating cylinder 1, a filter element 31 and a pipe fitting groove are arranged in the filter pumping frame 3, a filter water tank is arranged at the rear side of the filter pumping frame 3, a limiting member 5 that is rotatably connected to the upper and lower parts of the rotating cylinder 1 is fixedly connected to the workbench 2, and the upper part of the filter pumping frame 3 is fixedly connected to the limiting member 5.

[0036] Adopting the technical solution of this embodiment, the driving mechanism drives the workbench 2 to rotate. First, the untreated sewage is placed in the rotating cylinder 1. When the rotating cylinder 1 rotates at a high speed, the sewage in the rotating cylinder 1 moves along the inner wall of the rotating cylinder 1 under the action of centrifugal force. The filtering and pumping frame 3 is long and fixed in position. The filtering member 31 filters the sewage. The pipe slot is used to place the siphon pipe, and the filtered sewage is discharged through the siphon effect. At the same time, the sewage not sucked away by the siphon pipe is discharged through the filtering water tank and is filtered when it rotates to the position of the filtering member 31 next time. The limiting member 5 is used to make the rotating cylinder 1 rotate stably and fix the filtering and pumping frame 3 at the same time, avoiding the change of the position of the filtering and pumping frame 3, so that the rotating cylinder 1 rotates relative to the filtering and pumping frame 3.

[0037] Refer to Figure 1 and 6 : The driving mechanism includes a driving motor 41 and a rotating disk 42. The output shaft of the driving motor 41 is in transmission connection with the rotating disk 42, and the rotating disk 42 is fixedly connected to the bottom of the rotating cylinder 1.

[0038] In this embodiment, the rotating disk 42 is an intermediary for the driving motor 41 to drive the rotating barrel 1 to rotate. By controlling the rotation of the driving motor 41, the rotation of the rotating cylinder 1 is controlled.

[0039] Refer to Figures 1-2 : The limiting member 5 includes a support ring 51 and a limiting ring 52. The support ring 51 is fixedly connected to the upper side of the workbench 2. A connecting bar 53 is fixedly connected between the support ring 51 and the limiting ring 52. The bottom of the rotating cylinder 1 is slidably connected to the support ring 51, the limiting ring 52 is located above the rotating cylinder 1, and the connecting bar 53 is slidably connected to the outer side of the rotating cylinder 1.

[0040] In this embodiment, the support ring 51 is used to support the bottom of the rotating cylinder 1 and at the same time enable the rotating cylinder 1 to rotate within the support ring 51. The limiting ring 51 limits the position of the upper part of the rotating cylinder 1 to prevent the position of the rotating cylinder 1 from skewing during rotation. The connecting bar 53 plays a role of connection and limitation.

[0041] Refer to Figure 4 : The cross-section of the filtering and pumping frame 3 is U-shaped, and the inner side is an arc that fits the inner wall of the rotating cylinder 1. The upper end of the filtering and pumping frame 3 is fixedly connected to the limiting ring 52.

[0042] In this embodiment, the inner side of the filtering and pumping frame 3 rotates relative to the inner wall of the rotating cylinder 1. When the rotating cylinder 1 rotates, the sewage enters the filtering and pumping frame 3 from the opening of the filtering and pumping frame 3 and passes through the filtering member 31 and the filtering water tank in sequence.

[0043] Refer to Figures 2-3 : The filtering member 31 is slidably connected inside the filtering and pumping frame 3, and the opening of the filtering member 31 faces the side of the tangent direction of the rotation of the rotating cylinder 1.

[0044] In this embodiment, the cross-section of the filter element 31 is the same as that of the filter pumping frame 3, both being U-shaped. Baffles are fixedly connected to both sides of the opening of the filter element 31 and are in contact with the opening side of the filter pumping frame 3. Thus, the sewage entering the filter pumping frame 3 will only be discharged after being filtered.

[0045] Refer to Figure 2 : A support plate 21 lower than the plane of the workbench 2 is connected to one side of the workbench 2. A collecting member 6 with a receiving cavity is placed on the upper side of the support plate. A siphon tube 7 is connected in the pipe fitting groove of the collecting member 6 and the filter pumping frame 3.

[0046] In this embodiment, the support plate 21 is used to support the collecting member 6, so that the lower end of the siphon tube 7 can be located inside the collecting member 6. Thus, the siphon tube 7 can transport the water in the rotating cylinder 1 into the rotating cylinder 1.

[0047] Refer to Figure 3 : A fixing strip 8 is fixedly connected to the limiting ring 52. A scraping plate 81 is hinged to the fixing strip 8. The scraping plate 81 is directly above the upper opening of the filter element 31.

[0048] In this embodiment, the fixing strip 8 is used to hinge the scraping plate 81 so that the scraping plate 81 can rotate. When the rotating position of the scraping plate 81 is directly above the filter element 31, the filter element 31 is moved upward, and the scraping plate 81 scrapes the impurities filtered by the filter element 31, causing the impurities to concentrate at the lower part of the filter element 31. Before the filter element 31 is taken out, the scraping plate 81 is rotated in the other direction, and the filter element 31 can be completely taken out from the filter pumping frame 3.

[0049] Refer to Figure 2 : A handle 9 is fixedly connected to the upper side of the filter element 31.

[0050] In this embodiment, the cross-section of the handle is right-angled, and it is convenient to take the filter element 31 through the handle.

[0051] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0052] The above embodiments only exemplarily illustrate the principles and effects of the present utility model, rather than limiting the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
