[0001] The utility model relates to a weighing type material receiver, belonging to the technical field of material receivers. Background Art

[0002] At present, with the development of industrial automation technology, the receipt and management of materials occupy an important position in the production process. The weight of materials is a key factor affecting product quality and production costs. Therefore, accurate material weighing is particularly important.

[0003] After searching the prior art, we discovered Chinese patent publication number CN205820371U, which discloses a material receiver with an integrated weighing function. During use, we discovered that powders tend to float during conveying, leading to inaccurate weighing. This not only reduces material management efficiency but also affects production quality control. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a weighing material receiver, which can improve the efficiency of weighing powder materials and ensure that the materials fall smoothly.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a weighing material receiver, comprising:

[0006] The barrel is a hollow cylindrical structure with at least one feed port on its side wall and a discharge port at its bottom. A first control valve is provided on the discharge port. A plurality of weighing support legs are provided at intervals along the circumferential direction on the outer side wall of the barrel;

[0007] A pulse backwash filter assembly is installed on the top of the barrel. The pulse backwash filter assembly includes a filter assembly and a pulse backwash assembly. The filter assembly is connected to the interior of the barrel. The filter assembly is suitable for filtering and separating floating materials. The pulse backwash assembly is suitable for cleaning material dust accumulated on the surface of the filter assembly.

[0008] A weighing assembly is provided outside the barrel and includes:

[0009] Fixed plate;

[0010] A load plate, the load plate being mounted on the bottom of the weighing support foot of the barrel;

[0011] A support plate, the support plate being composed of a vertical plate segment and a horizontal plate segment perpendicular to each other, wherein the vertical plate segment is fixed to the fixing plate, and the horizontal plate segment extends below the load plate and is parallel to the load plate;

[0012] A weighing sensor is installed between the load plate and the support plate.

[0013] Furthermore, a specific structure of a filter assembly is provided, the filter assembly comprising:

[0014] A filter cartridge, the filter cartridge being arranged on the top of the material barrel and being in communication with the material barrel;

[0015] A plurality of cylindrical filter elements are vertically installed inside the filter cartridge.

[0016] Furthermore, a specific structure of a pulse recoil assembly is provided, wherein the pulse recoil assembly comprises:

[0017] A gas storage tank, which is installed on the outside of the barrel and is provided with at least one gas outlet;

[0018] A pulse backflush tube, one end of which is connected to the corresponding air outlet, and the other end of which passes through the filter cartridge and extends into the corresponding cylindrical filter element;

[0019] A second control valve is provided on the pulse backflush pipe.

[0020] Furthermore, the barrel is composed of an upper constant-diameter barrel section and a lower conical section that are connected, wherein:

[0021] The conical section is in a truncated cone shape, with an inner diameter that is larger at the top and smaller at the bottom, and the bottom end of the conical section is a discharge port.

[0025] By adopting the above technical solution, the utility model has the following beneficial effects:

[0026] In this utility model, the first control valve closes the barrel's discharge port. After material enters the barrel through the inlet, the filter assembly is activated to separate and filter floating material. Once the floating material within the barrel is substantially separated, the pulse recoil assembly is activated to clean accumulated material dust from the filter assembly's surface, allowing this dust to re-enter the barrel. Next, the weighing assembly weighs the material. This entire process effectively improves the precision and efficiency of powder material reception and discharge, enhancing the accuracy of both material reception and weighing.

[0027] In addition, the vibrating hammer installed on the outer wall of the barrel enhances the fluidity of the material and can effectively prevent the material from agglomerating or bridging in the barrel, ensuring that the material can flow smoothly during discharge, reducing the risk of blockage and further improving operating efficiency.

[0034] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0035] like Figure 1-5 As shown, a weighing material receiver includes:

[0036] The barrel 1 is a hollow cylindrical structure with a feed port 11 on its side wall and a discharge port 12 at the bottom. The discharge port 12 is provided with a first control valve. Three weighing support legs 13 are provided at intervals along the circumferential direction on the outer wall of the barrel 1.

[0037] The pulse backwash filter assembly 2 is installed on the top of the barrel 1. The pulse backwash filter assembly 2 includes a filter assembly and a pulse backwash assembly. The filter assembly is connected to the inside of the barrel 1. The filter assembly is suitable for filtering and separating floating materials, and the pulse backwash assembly is suitable for cleaning material dust accumulated on the surface of the filter assembly.

[0038] The weighing component 3 is arranged outside the barrel 1 and includes:

[0039] Fixed plate 31;

[0040] The load plate 32 is mounted on the bottom of the weighing support foot 13 of the barrel 1;

[0041] The support plate 33 is composed of vertical plate segments and horizontal plate segments that are perpendicular to each other, wherein the vertical plate segments are fixed to the fixed plate 31, and the horizontal plate segments extend below the load plate 32 and are parallel to the load plate 32;

[0042] The weighing sensor is installed between the load plate 32 and the support plate 33 .

[0043] In this embodiment, if Figure 1-2 and Figure 4 As shown, the first control valve is first used to close the discharge port 12 of the barrel 1. After the material enters the barrel 1 through the feed port 11, the filter assembly is activated to separate and filter the floating material. Once the floating material within the barrel 1 is substantially separated, the pulse recoil assembly 2 is activated to clean the material dust accumulated on the surface of the filter assembly, which is then re-entered into the barrel 1. Next, the weighing assembly 3 weighs the material. This entire process effectively improves the accuracy and efficiency of powder material reception and discharge, avoiding issues with inaccurate material reception and weighing.

[0044] Specifically, such as Figure 1-2 and Figure 4 As shown, the filter component may have the following structure, including:

[0045] The filter cartridge 21 is arranged on the top of the barrel 1 and is connected to the barrel 1;

[0046] Six cylindrical filter elements 22 are vertically installed inside the filter cartridge 21 .

[0047] In some embodiments, the number of cylindrical filter elements 22 is not limited to six and can be set according to specific needs.

[0048] Specifically, such as Figure 1-2 and Figure 4-5 As shown, the pulse recoil component can have the following structure, including:

[0049] The gas storage tank 24 is installed on the outside of the barrel 1 and is provided with three gas outlets;

[0050] A pulse backflush tube 25, one end of which is connected to the corresponding air outlet, and the other end of which passes through the filter cartridge 21 and extends into the corresponding cylindrical filter element 22;

[0051] The second control valve is provided on the pulse backflush pipe 25 .

[0052] In this embodiment, if Figure 1-2 and Figure 4-5 As shown, the pulse backflush assembly operates by using compressed air for reverse blowing, clearing dust accumulated on the surface of cylindrical filter element 22. An air reservoir 24, mounted outside barrel 1, stores compressed air for backflush. A pulse backflush pipe 25 connects air reservoir 24 to cylindrical filter element 22. When cleaning is required, the second control valve is opened, and compressed air enters the filter element through pulse backflush pipe 25, blowing the cylindrical filter element 22 from the inside out, dislodging any adhering dust.

[0053] In actual use, the number and size of the cylindrical filter elements 22 can be adjusted according to actual needs to adapt to different filtering requirements. In addition, in this embodiment, each air outlet of the air storage tank 24 corresponds to two cylindrical filter elements 22.

[0054] Specifically, such as Figure 1-2 As shown, the barrel 1 is composed of an upper constant diameter barrel section and a lower conical section connected to each other, wherein:

[0055] The conical section is in the shape of a truncated cone, with an inner diameter that is larger at the top and smaller at the bottom, and the bottom end of the conical section is a discharge port.

[0056] In this embodiment, the upper constant-diameter cylindrical section provides sufficient volume for storing and processing materials, and the frustum-shaped design of the lower conical section is conducive to the gathering and flow of materials. The design of the conical section with the inner diameter gradually decreasing from top to bottom can naturally guide the material to move toward the discharge port under the action of gravity, thereby improving the smoothness and efficiency of the discharge.

[0057] Specifically, such as Figure 1-2 As shown, the weighing material receiver further includes two vibrating hammers 4 , which are mounted on the outer side wall of the barrel 1 .

[0058] Specifically, such as Figure 1-2 As shown, two vibration hammers 4 are provided, and the two vibration hammers 4 are fixedly installed on the outer wall of the barrel 1 at intervals along the circumferential direction of the outer wall of the barrel 1 .

[0059] In this embodiment, if Figure 1-2 As shown, the function of the vibrating hammer 4 is to resolve problems such as material adhesion, agglomeration, and bridging within the barrel 1. By generating mechanical vibrations, the vibrating hammer 4 effectively loosens and breaks up any material accumulation that may have formed on the inner wall of the barrel 1 or near the discharge port, ensuring smooth material flow and discharge. Specifically, the vibrating hammer 4 can be an electromagnetic vibrator.

[0060] Specifically, such as Figure 1-2 As shown, the first control valve is a pneumatic butterfly valve 5 .

[0061] In this embodiment, if Figure 1-3As shown, the pneumatic butterfly valve 5 features a simple structure, compact size, and light weight, enabling rapid opening and closing. Its operating principle is to use compressed air to drive the valve plate to rotate, thereby achieving on-off control. This design is not only easy to operate but also highly reliable, making it particularly suitable for use in dusty or harsh environments.

[0062] This embodiment also includes a controller, which is respectively connected to the pneumatic butterfly valve 5, the weighing sensor, and the pulse backwash filter assembly. The weighing sensor installed between the load plate 32 and the support plate 33 feeds back the weight signal to the controller, allowing the user to set the suction weight directly on the controller, thereby achieving the purpose of accurate measurement. The feedback of the weight signal can be used not only to control the feeding process, but also to monitor the discharge situation. It helps to reduce material waste and improve production efficiency. In addition, the weight data can be further written into a report to count the material consumption. This provides users with a detailed record of material consumption, which is convenient for subsequent cost accounting, inventory management and production analysis.

[0063] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
