Description

Technical Field

[0001] This utility model relates to the field of cement weighing technology, specifically to a bulk cement weighing device. Background Technology

[0002] Bulk cement refers to cement that is shipped directly from the factory, transported, and stored for use without being packaged in paper bags (including woven plastic bags, composite bags, etc.) or any other small materials, using specialized equipment (including bulk cement dispensing facilities, specialized transport vehicles, and storage tanks). Bulk cement is characterized by mechanized transportation and storage, stable and reliable quality, high cost-effectiveness, significant environmental advantages, and ease of use. In practical applications, bulk cement production enterprises also need to be equipped with complete measuring instruments to strictly control the cement production and transportation process and ensure the stability of bulk cement output.

[0003] The patent with publication number CN212424721U discloses a cement quantitative bulk dispensing device, including an outer frame, a support frame at the top of the outer frame, a first hopper inside the support frame, an inner frame inside the outer frame, the top of the inner frame being connected to the top inner side of the outer frame by a fixing member, a second hopper below the top of the outer frame, the discharge end of the first hopper being connected to the inlet end of the second hopper, a rotor scale for cement metering being disposed between the first and second hoppers, a sleeve being fitted on the outer wall of the discharge end of the second hopper, the sleeve being connected to the top of the inner frame by a fixing member, a connector being disposed below the sleeve, and a vertically movable discharge pipe being connected to the bottom end of the connector. The purpose is to overcome the shortcomings of the prior art and provide a cement quantitative bulk dispensing device that can automatically weigh and measure cement and is easy to use.

[0004] Although the above-mentioned device enables automatic weighing and metering of bulk cement, it still has the following shortcomings:

[0005] When using the device, since there is no corresponding cement storage device, cement must be added back to the metering hopper every time it needs to be metered. This operation is complicated and inconvenient for the staff. At the same time, the device does not have a structure to prevent cement from falling, so it is impossible to avoid residual cement entering when the required volume of cement is reached, which affects the accuracy of cement metering. Especially when dealing with small doses, these accidentally dropped cement will have a significant impact on the metering. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a bulk cement weighing device that solves the problem of cement accidentally entering the weighing structure during the metering process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bulk cement weighing device, comprising a weighing device body, a feeding opening on the top surface of the weighing device body, a discharge slide plate on the bottom surface of the weighing device body, a cement storage component at the upper end of the weighing device body, a cement metering component connected to the cement storage component below the cement storage component, a storage partition for fixing the cement storage component on the weighing device body, a metering partition for fixing the cement metering component on the weighing device body, a first connection opening on the storage partition, and a second connection opening on the metering partition.

[0008] Furthermore, the cement storage assembly includes a cement storage hopper and a ball valve located at the discharge port at the lower end of the cement storage hopper. The discharge port is fitted with the upper end of the ball valve. The ball valve is connected to a drive motor. A motor slot plate is provided outside the drive motor. The motor slot plate is fitted with the top surface of the storage partition. The storage partition is fitted with the lower end of the ball valve.

[0009] Furthermore, the cement metering assembly includes a cement metering and storage box that is attached to the lower end of the ball valve and a rotor scale located below the cement metering and storage box. The cement metering and storage box has an inlet that is attached to the lower end of the ball valve. A conical hopper is installed inside the cement metering and storage box. The outlet of the conical hopper is connected to the rotor scale. A shut-off valve is installed between the outlet and the rotor scale. The shut-off valve is connected to a second drive motor. A second motor slot plate is installed outside the second drive motor. The second motor slot plate is attached to the top surface of the rotor scale. The lower end of the rotor scale is attached to the discharge slide plate. The metering partition is attached to the bottom surface of the cement metering and storage box.

[0010] Furthermore, the feed opening is a threaded opening, and the feed opening is provided with a corresponding threaded cover. An observation port is provided in the middle of the threaded cover, and an observation window is provided at the observation port.

[0011] Furthermore, a surveillance camera can be installed at the observation port.

[0012] Furthermore, the cement storage hopper has metering scales on its inner surface.

[0013] Furthermore, a control panel is provided on the outside of the weighing device body.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] During use, the cooperation of the ball valve and the shut-off valve can prevent cement from accidentally entering the rotor scale and being loaded, thus avoiding discrepancies between the measurement data and the actual loading quantity. When it is necessary to measure a large amount of cement, the cement metering storage box with a fixed volume can be used to measure the cement in batches in a "small amount, multiple times" manner, ensuring the accuracy of the measurement. At the same time, the "small amount, multiple times" method can reduce the working time of the rotor scale and extend its service life. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 4 As shown, a bulk cement weighing device includes a weighing device body 1, a feeding opening 101 on the top surface of the weighing device body 1, a discharge slide plate 102 on the bottom surface of the weighing device body 1, a cement storage component 2 at the upper end inside the weighing device body 1, a cement metering component 3 connected to the cement storage component 2 below the cement storage component 2, a storage partition 103 for fixing the cement storage component 2, and a metering partition 104 for fixing the cement metering component 3. The storage partition 103 has a first connection opening 105, and the metering partition 104 has a second connection opening 106.

[0023] like Figure 1As shown, the bulk cement weighing device in this utility model is structurally similar to existing weighing devices. For example, patent CN212424721U discloses a quantitative bulk cement weighing device. The main improvement of this utility model is that it can prevent cement from accidentally entering the weighing structure during the weighing process. Figures 1 to 4 As shown, in the bulk cement weighing device of this utility model, during use, first open the top threaded cap 107 and add cement into the cement storage hopper 201. At this time, the ball valve 202 below the cement storage hopper 201 will be closed. During storage, the operator can observe the measuring scale 206 on the inner wall of the cement storage hopper 201 to estimate the volume of cement added, facilitating the next addition. After adding, the threaded cap 107 is re-secured. If cement needs to be loaded, move the loading object under the discharge slide plate 102 and open the ball valve 202. The cement in the cement storage hopper 201 will enter the cement metering and storage box 301. When a large amount of cement is needed in one measurement, first close the shut-off valve 306 and open the cement metering and storage box 301. When the storage box 301 is full, closing the ball valve 202 and opening the shut-off valve 306 allows for the measurement of cement in one cement metering storage box 301. Since the volume of the cement metering storage box 301 is fixed, the discharge volume can be accurately estimated, facilitating preliminary statistics by staff. If more cement is needed, this step can be repeated. Subsequently, the cement will be measured by the rotor scale 302 and enter the discharge slide plate 102 for loading. When performing the above steps for the last time or measuring a small amount of cement, we first open the shut-off valve 306 and slowly lower the cement by controlling the opening degree of the ball valve 202. This allows the rotor scale 302 to accurately measure the mass of the cement, and closes the shut-off valve 306 when the required weight of cement is reached to complete the measurement, ensuring the consistency of the measurement and loading weight to the greatest extent.

[0024] like Figure 2 and Figure 4 As shown, the cement storage assembly 2 includes a cement storage hopper 201 and a ball valve 202 disposed at a discharge port 203 at the lower end of the cement storage hopper 201. The discharge port 203 is attached to the upper end of the ball valve 202. The ball valve 202 is connected to a drive motor 204. A motor slot plate 205 is disposed outside the drive motor 204. The motor slot plate 205 is attached to the top surface of the storage partition 103. The storage partition 103 is attached to the lower end of the ball valve 202.

[0025] Specifically, after cement enters the cement storage hopper 201 through the feed opening 101, the timing and speed of cement falling are determined by controlling the degree of closure of the ball valve 202. The ball valve 202 is controlled by the control panel 109 and driven by the drive motor 204. The placement of the storage partition 103 can help fix the cement storage assembly 2 and improve the stability of the structure.

[0026] like Figure 2 and Figure 4 As shown, the cement metering assembly 3 includes a cement metering storage box 301 that is attached to the lower end of the ball valve 202 and a rotor scale 302 disposed below the cement metering storage box 301. The cement metering storage box 301 has an inlet 303 that is attached to the lower end of the ball valve 202. A conical hopper 304 is disposed inside the cement metering storage box 301. The outlet 305 of the conical hopper 304 is connected to the rotor scale 302. A shut-off valve 306 is disposed between the outlet 305 and the rotor scale 302. The shut-off valve 306 is connected to a second drive motor 307. A second motor slot plate 308 is disposed outside the second drive motor 307. The second motor slot plate 308 is attached to the top surface of the rotor scale 302. The lower end of the rotor scale 302 is attached to the discharge slide plate 102. The metering partition 104 is attached to the bottom surface of the cement metering storage box 301.

[0027] Specifically, when a large quantity of cement needs to be measured at once, by utilizing the cement metering storage box 301 with a fixed volume, we can control the ball valve 202 and the shut-off valve 306 to measure the cement in batches in small quantities, ensuring the accuracy of the measurement. At the same time, when the volume of a single measurement is less than the volume of the cement metering storage box 301, the metering process is slowed down by controlling the degree of closure of the ball valve 202, giving the operator more reaction time to control the device and close the shut-off valve 306 at the appropriate time, thus ensuring the consistency of the measurement and loading weight as much as possible.

[0028] like Figure 3 As shown, the feed opening 101 is a threaded opening, and the feed opening 101 is provided with a corresponding threaded cover 107. An observation port 108 is provided in the middle of the threaded cover 107, and an observation window is provided at the observation port 108.

[0029] like Figure 3 As shown, a surveillance camera can also be installed at observation port 108.

[0030] Specifically, by setting a threaded opening and a threaded cover 107, we can seal the device without delaying the storage of cement. When needed, the feed opening 101 can be opened to facilitate long-term metering and loading processes. The observation port 108 on the threaded cover 107 allows staff to easily observe changes in the cement storage volume. It can also be observed by setting a monitoring camera, further reducing the number of operation steps and making it easier for staff to observe.

[0031] like Figure 4 As shown, the cement storage hopper 201 has a metering scale 206 on its inner surface.

[0032] Specifically, the measuring scale 206 allows us to intuitively estimate the amount of cement stored in the cement storage hopper 201, making it easier for staff to observe.

[0033] like Figure 1 and Figure 2 As shown, a control panel 109 is provided on the outside of the weighing device body 1.

[0034] Specifically, a control panel 109 is installed on the outside of the weighing device body 1 to facilitate operators to observe data and control the device in real time.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
