This utility model discloses a novel sealing structure for a filter unit of a PTA pressure filter, including a filter tank and a filter unit installed inside it. The filter unit includes a filter base, a sealing ring, fixing bolts, a non-asbestos gasket, and a ring gasket. The filter base is installed inside the filter tank, and has a through-hole at its center for allowing filtered liquid to flow out. The sealing ring is embedded in the through-hole of the filter base. The filter tank has a liquid outlet at its center that communicates with the through-hole. A non-asbestos gasket is pressed between the bottom surface of the filter base and the bottom upper surface of the filter tank. The filter base, filter tank, and non-asbestos gasket are fastened together by several fixing bolts. The non-asbestos gasket has a liquid passage hole at its center that corresponds to the through-hole and the liquid outlet, and the wall of the liquid passage hole is covered with a ring gasket. This utility model improves the structure of the sealing gasket to prevent liquid from eroding it.

The invention discloses a bispecific antibody-UC-MSCs preparation for targeting prostate diseases as well as preparation and application of the bispecific antibody-UC-MSCs preparation. The preparation comprises a bispecific antibody BsAb-1 and human umbilical cord mesenchymal stem cells (UC-MSCs), the BsAb-1 is formed by connecting an anti-CD105 single-domain antibody, an anti-PSCA single-domain antibody and a flexible peptide linker in series, wherein the amino acid sequence of the BsAb-1 is as shown in SEQ ID NO: 4. According to the preparation, the UC-MSCs are delivered to a prostate focus through the targeting bridge effect of BsAb-1, the focus enrichment amount within 72 hours is increased by 6.3 times compared with that of pure UC-MSCs, and meanwhile retention of non-target organs such as the liver and the spleen is reduced. The preparation can effectively relieve inflammatory response and fibrosis of chronic prostatitis, and the curative effect of the preparation is remarkably superior to that of pure UC-MSCs treatment. Precise targeted treatment of prostate diseases is achieved, the curative effect is remarkably better than that of a traditional stem cell therapy method, and high clinical application value is achieved.

The present application relates to the technical field of petroleum chemical industry, in particular to a kind of heterogeneous synthesis device and method of cyclohexanone oxime.The synthesis device of the present application includes vortex reactor, rotating rod and stirrer;By inserting rotating rod in vortex reactor, annular reaction zone with gap size of 0.5mm-5mm is formed, under the dual action of microscale effect and rotating field, mass transfer resistance is reduced, reaction liquid and catalyst particles are fully contacted, and reaction liquid can be broken into smaller droplets under the shear force provided by rotating field, so that the contact area of oil-water two phases is increased, fully emulsified, uniformly mixed, and the flow distribution of catalyst particles is more uniform, the efficiency of catalytic reaction is improved;At the same time, the concentration distribution of hydrogen peroxide in annular reaction zone is controlled by cooperating with multi-stage feeding mode of hydrogen peroxide, so that the concentration of hydrogen peroxide is matched with the rate of catalytic reaction, thereby improving the utilization rate of hydrogen peroxide, and realizing the efficient synthesis of cyclohexanone oxime.

The present invention discloses a garbage recycling box bag separation control method and control system, comprising an identification module, a control module, a data processing module, a sensing module and a data storage module; wherein the identification module is used to obtain target garbage information and store the obtained target garbage information in the data storage module; the target garbage information in the data storage module is processed by the data processing module to establish a three-dimensional model of the target garbage. The garbage recycling box bag separation control method and control system obtains the shape information of the target garbage, determines the separation end and the target garbage positioning end of the target garbage, facilitates the clamping of the garbage and the separation of the garbage bags, and in the process of clamping the target garbage, effectively reduces the garbage retention in the garbage bag by using the setting of the first clamp and the second clamp, and effectively improves the separation rate of the target garbage bags.

The utility model discloses a liquid mixture filtering device, and relates to the technical field of filtering devices, the filtering device comprises a rack, a stirring tank and a filtering tank, the stirring tank and the filtering tank are both arranged on the rack, the rack is provided with a first feeding pipe communicated with the interior of the stirring tank, and the top of the filtering tank is vertically provided with a second feeding pipe; a stirring mechanism is arranged in the stirring tank, and a liquid mixture stirred by the stirring mechanism can flow into the filtering tank through the second feeding pipe; a variable cross-section filtering assembly is arranged in the filtering tank and is positioned below the second feeding pipe. The stirring tank is used for containing a liquid mixture needing to be stirred and filtered. The stirring mechanism is used for fully stirring the liquid mixture in the stirring tank. The variable-cross-section filtering assembly is mounted in the filtering tank, and the retention volume of a liquid mixture on the variable-cross-section filtering assembly can be reduced through the variable-cross-section design, so that the probability that filtering holes are blocked is reduced, and the filtering speed of the liquid mixture is increased.
