Description

Technical Field

[0001] The utility model relates to the technical field of powder screening, in particular to a screening device for blood powder removal production and processing. Background Art

[0002] In order to remove blood stains on clothes, people will buy washing powder that can remove blood stains, also known as blood removal powder, blood removal powder, etc. It includes a variety of incubation surfactants, decomposition of grease solubilizers, etc., and has excellent removal ability for drug stains, blood stains, protein, and fat dirt. Similarly, its production steps are the same as those of ordinary washing powder, but the raw materials are different.

[0003] As mentioned above, in the process of blood removal powder production, it needs to go through multiple production steps, including fully mixing multiple raw materials, drying raw materials, packaging, etc. During the mixing process, the mixed materials need to be cut to form fine powders. In addition, when mixing multiple raw materials, a mixing agent needs to be added. Therefore, the mixed raw materials are moist and the cut parts of the raw materials are bonded together. In order to improve the dryness of the powder, a spray dryer is needed to dry the powder to facilitate the packaging of the powder.

[0004] At present, there are many kinds of spray dryers on the market, such as a spray dryer disclosed in a Chinese patent with patent number CN116271886B, which includes a drying tower and a feeding system that conveys materials to the drying tower through an atomizer. The drying tower includes a cylindrical tower body and an inverted conical tower bottom. The top of the cylindrical tower body is provided with a volute hot air distributor connected to the air supply system, and the side of the inverted conical tower bottom is provided with an air outlet, and is connected in sequence to a combined cyclone and a multi-bin bag dust collector through a pipeline, and the top side of the multi-bin bag dust collector is connected to an induced draft fan through a pipeline; a spherical bearing located on the axis of the drying tower is connected to the inner wall of the inverted conical tower bottom in the drying tower through a fixed rod, and a purge rod is rotatably installed in the spherical bearing, and a plurality of air blowing ports for blowing the conical inner wall are opened along the length direction of the purge rod, and a driving mechanism for driving the purge rod to rotate is installed on the inverted conical tower bottom outside the drying tower; or as shown in the attached Fig. 9 The spray dryer shown. Regardless of the type of spray dryer, the principle is the same, which is to dry the powder through high-temperature spraying.

[0005] However, as mentioned in the second paragraph, since the powder after mixing is moist, some materials will stick together. In this case, it is very likely that after drying, it will stick together to form large particles. If the powder output from the spray dryer is not filtered, large particles will be packaged and sold, which will reduce the user experience and damage the reputation of the factory.

[0029] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0030] Example 1

[0031] In order to solve the problem described in the background technology that the dry powder is not filtered, resulting in large-sized materials being packaged and sold, damaging the reputation of the factory, this embodiment provides a screening device, which is installed at the output port of the spray dryer material to intercept large-sized materials.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 As shown, specifically, the screening device includes a feed barrel 1, a support frame 2 and a filter element 3. The feed barrel 1 is set as a conical structure, a valve body is set at the lower end, and an opening is set at the upper end. A top plate 12 is set at the opening of the feed barrel 1, and a valve body is also set at the upper end of the top plate 12. The valve body of the top plate 12 is connected to the material output port of the spray dryer. The support frame 2 is set between the feed barrel 1 and the top plate 12. In addition, two groups of filter elements 3 are set, and the two groups of filter elements 3 can be distributed up and down and penetrate the support frame 2 at the same time, or can be alternately penetrated and installed at the support frame 2. When the dried material is output from the output end of the spray dryer, it will fall into the space formed by the top plate 12 and the feed barrel 1, and be intercepted by the filter element 3. Under the action of the filter element 3, the material that meets the size falls and is output from the lower end of the feed barrel 1, and the larger size of the material is intercepted on the filter element 3. Because the filter element 3 is set through the support frame 2, the staff can regularly disassemble the filter element 3 to remove the material accumulated on the filter element 3. When two sets of filter devices 3 are simultaneously installed through the support frame 2, after the upper filter device 3 is removed, the lower filter device 3 is used to intercept large-sized materials to avoid affecting the filtration of materials due to the removal of the intercepted impurities. If the two sets of filter devices 3 are alternately installed on the support frame 2, the other set of filter devices 3 can be installed on the support frame 2 before the filter devices 3 are removed, so that the materials can be filtered after the filter devices 3 are removed.

[0033] like Figure 2As shown, in order to realize the installation of the support frame 2, a plurality of connecting rods 13 are arranged through the edge of the top plate 12, and the lower ends of the connecting rods 13 are arranged through the edge of the top of the feeding tube 1. Under the action of the connecting rods 13, the feeding tube 1 is stably and spaced below the top plate 12, providing space for the installation of the support frame 2. In addition, the support frame 2 is arranged as a three-dimensional structure, and a through hole is arranged in the middle part, which is connected with the top plate 12 and the feeding tube 1. Then, the material falling into the top plate 12 will pass through the through hole and fall into the feeding tube 1, so that the material is discharged.

[0034] like Figure 4 As shown, in order to realize the detachable connection between the filter device 3 and the support frame 2, two inlet and outlet holes 21 are arranged on the side wall of the support frame 2, and the filter device 3 passes through the inlet and outlet holes 21 and completely covers the through hole. In addition, a limit bolt 32 is threadedly inserted on the side wall of the filter device 3, and the limit bolt 32 passes through the support frame 2. Therefore, when the filter device 3 needs to be removed, the limit bolt 32 is rotated to release the restriction of the filter device 3 and the support frame 2, and the filter device 3 can be removed. Of course, if the filter device 3 is to be separated from the support frame 2, it is necessary to remove a connecting rod 13 facing the filter device 3. After removing one, there are still three connecting the top plate 12 and the feed barrel 1, and under the action of the support frame 2, the feed barrel 1 can be stably installed below the top plate 12.

[0035] like Figure 5 , Figure 6 As shown, in order to filter the material, the filter element 3 includes an outer frame and a filter screen 31. A support rod 34 is provided at the bottom of the inner side of the outer frame. The filter screen 31 is supported on the support rod 34, and the upper side surface is lower than the upper side surface of the outer frame. The height of the outer frame is slightly smaller than the height of the inlet and outlet holes 21, and a handle 33 is provided at the end of the outer frame. Under the action of the filter screen 31, large-sized materials are effectively intercepted. Under the action of the support rod 34, the filter screen 31 can be supported so that the filter screen 31 can be placed stably. Because the upper side surface of the filter screen 31 is lower than the upper side surface of the outer frame, the intercepted materials are accumulated on the filter screen 31. When it is necessary to clean the materials, the staff can hold the handle 33 to pull the unrestricted filter element 3 to move, so that the filter element 3 is separated from the support frame 2, and the materials are cleaned. When two groups of filter elements 3 are alternately arranged on the support frame 2, the inlet and outlet holes 21 without filter elements 3 can be filled with the plate body to block the inlet and outlet holes 21. The plate body can also be provided with a limit bolt 32, and the limit bolt 32 is arranged through the support frame 2, that is, the connection placement is the same as that of the outer frame and the support frame 2. The device provided in this embodiment is mainly used for a spray dryer, so when the spray dryer dries other powders, it can also work to filter powders.

[0036] Example 2

[0037] like Figure 1 , Figure 4 As shown, on the basis of Example 1, in order to avoid the slow descent of materials that meet the size due to the accumulation of large-size materials, rubber ring plates 22 are arranged at the upper and lower ends of the through hole of the support frame 2, and the two rubber ring plates 22 are connected to the feeding barrel 1 and the top plate 12. A rod body is arranged at the end of the lower side of the support frame 2, and a spring 24 is sleeved on the outer side of the rod body. A support plate 23 is arranged in parallel below the support frame 2, and the support plate 23 is fixedly connected to the feeding barrel 1. The lower end of the rod body passes through the support plate 23, and the spring 24 is in a compressed state and is respectively connected to the support frame 2 and the support plate 23. At the same time, a double-axis motor is arranged on the top plate 12, and shaft bodies are arranged on the two output shafts of the double-axis motor. Cams 11 are sleeved at the ends of the two shaft bodies that are away from each other, and the two cams 11 contact the support frame 2 alternately. The rubber ring plate 22 and the spring 24 are arranged, and can be deformed under the action of external force, so as to facilitate the lifting and lowering of the support frame 2 and the filter element 3. Under the action of the dual-axis motor, the cam 11 rotates, forcing the support frame 2 to drive the filter element 3 to vibrate, thereby changing the position of the material relative to the filter element 3, providing convenience for the descent of the material that meets the size.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be modified and varied in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
