[0002] Polycarboxylate superplasticizer is a commonly used concrete admixture. It can significantly reduce the amount of cement used in concrete, improve the fluidity and pumpability of concrete, and also improve the workability and durability of concrete. After the polycarboxylate superplasticizer is prepared in the reactor, it is stored in the mother liquor tank. Then, other components are added to form the final product during subsequent use.

[0003] A search revealed that prior art CN221333659U discloses a polycarboxylate superplasticizer discharging device, including a storage tank. A top plate is fixedly connected to the top of the storage tank. Multiple stirring rods rotate inside the storage tank, and these rods are evenly distributed in a ring. A rotating mechanism for rotating the stirring rods is located inside the storage tank.

A discharge box is fixedly connected to the bottom of the top plate, positioned below the feeding port, and has a discharge mechanism inside. A filter box is fixedly connected to the bottom of the storage tank, and has a filtration mechanism inside. This invention, through the arrangement of multiple stirring rods, can stir the solution inside the storage tank, simultaneously driving multiple guide vanes to rotate, thereby stirring the solution while feeding and preventing clumping that could affect quality.

[0004] However, the above equipment has the following problems when in use: when the raw materials are mixed and discharged, the water-reducing agent is simply filtered, which cannot ensure the quality of the water-reducing agent. Utility Model Content

[0005] The purpose of this invention is to provide a discharge device for the compounding process of polycarboxylate superplasticizer, which solves the problem that existing devices simply filter the superplasticizer when it is discharged, and cannot ensure the quality of the superplasticizer.

[0006] To achieve the above objectives, this utility model provides a discharge device for the compounding process of polycarboxylate superplasticizer, including a storage tank, a discharge valve installed at the bottom of the storage tank, a feeding mechanism provided on the top cover plate, and an auxiliary mechanism;

[0007] The auxiliary mechanism includes a mounting frame, a collar, a retaining plate, a filter screen, an installation ring, an activated carbon filter plate, a limiting plate, and a connecting device. The mounting frame is installed inside the storage tank. The collar is assembled and installed inside the mounting frame after being connected by two retaining plates. The filter screen is welded inside the collar. The installation ring is integrally formed with the mounting frame by a rectangular block, and the activated carbon filter plate is installed in the stepped cavity at its bottom. The rectangular block is slidably connected to the two retaining plates respectively. The limiting plate is integrally formed with the retaining plates and slidably connected to the activated carbon filter plate, and has an L-shaped cross-section. The connecting device is located on the side of the storage tank near the cover plate.

[0008] The feeding mechanism includes a feeding pipe and a U-shaped cover. The feeding pipe is welded to the top of the cover plate and communicates with the storage tank. The U-shaped cover is detachably connected to the feeding pipe and is located on top of the feeding pipe.

[0009] The connecting device includes a connector and a mating component. The connector is arranged in a ring at intervals on the outside of the cover plate. The mating component is respectively arranged on the storage tank and the cover plate.

[0010] The mating components include an upper connecting block and a lower connecting block. The upper connecting block is integrally formed with the cover plate and mates with the connector. The lower connecting block is integrally formed with the storage tank, fits against the upper connecting block, and mates with the connector.

[0011] The discharge equipment used in the compounding process of polycarboxylate superplasticizer further includes an abutting mechanism, which includes a rectangular plate and an L-shaped plate. The rectangular plate is detachably connected to the mounting frame. The L-shaped plate is detachably connected to the rectangular plate, and its top end face abuts against the bottom end face of the cover plate.

[0012] This invention relates to a discharge device for the compounding process of polycarboxylate superplasticizer. This device is used in conjunction with a compounding device. The discharge port of the compounding device is higher than the height of the feeding mechanism, and a Z-shaped pipe is installed at the discharge port of the compounding device. During use, this device is placed below the discharge port of the Z-shaped pipe of the compounding device. The compounded raw materials are transported through the pipe into the feeding mechanism and then fall into a storage tank. The raw materials are first filtered through a filter screen, and then further filtered through an activated carbon filter plate. Finally, the discharge valve is opened to allow the materials to be discharged. Compared with the existing single-filtration structure, this application's dual filtration improves the impurity treatment effect and enhances the quality of the superplasticizer. This solves the problem that existing devices simply filter the superplasticizer during discharge, failing to ensure its quality. Attached Figure Description

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the discharge equipment used in the compounding process of polycarboxylate superplasticizer. Figure 2 This is a diagram showing the installation location of the filter screen. Figure 3This is a schematic diagram of the card plate structure. This utility model provides a discharge device for the compounding process of polycarboxylate superplasticizer: it includes a storage tank 101, a discharge valve 102, a cover plate 103, a feeding mechanism, and an auxiliary mechanism. The auxiliary mechanism includes a mounting frame 104, a collar 105, a card plate 106, a filter screen 107, a mounting ring 108, an activated carbon filter plate 109, a limiting plate 110, and a connecting device. The feeding mechanism includes a feed pipe 111 and a U-shaped cover 112. The connecting device includes a connector 113 and a mating component. The mating component includes an upper connecting block 114 and a lower connecting block 115. This solution solves the problem that existing devices simply filter the superplasticizer during discharge, failing to ensure its quality. It is understood that this solution can better guarantee the quality of the superplasticizer.

[0022] In this embodiment, a discharge valve 102 is installed at the bottom of the storage tank 101, and a feeding mechanism is provided on the top cover plate 103. The cover plate 103 is used for sealing the top of the storage tank 101.

[0023] The mounting bracket 104 is installed inside the storage tank 101. The collar 105 is assembled and installed inside the mounting bracket 104 after being connected by two clamping plates 106. The filter screen 107 is welded inside the collar 105. The mounting ring 108 is integrally formed with the mounting bracket 104 by a rectangular block 116, and the activated carbon filter plate 109 is installed in the stepped cavity at its bottom. The rectangular block 116 is slidably connected to the two clamping plates 106 respectively. The limiting plate 110 is integrally formed with the clamping plate 106 and slidably connected to the activated carbon filter plate 109, and has an L-shaped cross-section. The connecting device is located on the side of the storage tank 101 near the cover plate 103. The mounting bracket 104 has a mounting ring 108 integrally mounted on its bottom via symmetrically arranged rectangular blocks 116. The mounting ring 108 has a stepped cavity at its bottom for easy installation of the activated carbon filter plate 109. The outer surface of the collar 105 has a slot for easy engagement of the locking plate 106. Two locking plates 106 are connected by countersunk bolts, forming an integral circular structure that limits the collar 105. Simultaneously, the locking plate 106 has a sliding groove that engages with the rectangular blocks 116 to prevent rotation. The limiting plate 110 has an L-shaped cross-section, allowing it to directly limit the activated carbon filter plate 109 at the bottom during installation of the locking plate 106. The mounting bracket 104 is T-shaped, with its top mounting edge fixed to the stepped structure inside the storage tank 101 by bolts. The connecting device is used to fix the cover plate 103.

[0024] Secondly, the feed pipe 111 is welded to the top of the cover plate 103 and communicates with the storage tank 101; the U-shaped cover 112 is detachably connected to the feed pipe 111 and is located on top of the feed pipe 111. The U-shaped cover 112 is directly slidably installed on top of the feed pipe 111, and can be directly slid off when the equipment is in use.

[0025] Then, the connector 113 is arranged annularly at intervals on the outside of the cover plate 103; the mating components are respectively arranged on the storage tank 101 and the cover plate 103. The connector 113 adopts a T-shaped screw and a nut.

[0026] Finally, the upper connecting block 114 is integrally formed with the cover plate 103 and mates with the connector 113; the lower connecting block 115 is integrally formed with the storage tank 101, fits against the upper connecting block 114, and mates with the connector 113. Aligned through holes are provided on the upper connecting block 114 and the lower connecting block 115 respectively, facilitating the passage of the T-shaped screw of the connector 113.

[0027] This invention addresses the problem of existing devices that simply filter polycarboxylate superplasticizer during discharge, failing to ensure its quality. This device is used in conjunction with a compounding device. The discharge port of the compounding device is higher than the feeding mechanism, and a Z-shaped pipe is installed at the discharge port. During use, this device is placed below the vertically downward end of the Z-shaped pipe's discharge port. The compounded raw material is fed into the feeding pipe 111 and then falls into the storage tank 101. Upon entering, the raw material is first filtered through the filter screen 107, and then further filtered through the activated carbon filter plate 109. Finally, the discharged valve 102 is opened to discharge the filtered raw material for use. Compared to existing single-filtration structures, this dual filtration improves impurity removal and enhances the quality of the superplasticizer, thus solving the problem of existing devices simply filtering the superplasticizer during discharge, failing to ensure its quality.

[0028] Example 2:

[0029] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the structure of an L-shaped plate. Based on the first embodiment, this utility model provides a discharge device for the compounding process of polycarboxylate superplasticizer. The discharge device for the compounding process of polycarboxylate superplasticizer further includes an abutting mechanism, which includes a rectangular plate 201 and an L-shaped plate 202.

[0030] The rectangular plate 201 is detachably connected to the mounting bracket 104; the L-shaped plate 202 is detachably connected to the rectangular plate 201, with its top end face abutting against the inner bottom end face of the cover plate 103. The rectangular plate 201 is fixed by bolts, and the L-shaped plate 202 is connected to the rectangular plate 201 by countersunk bolts arranged from bottom to top, achieving vertical limitation after the cover plate 103 is installed to prevent movement, thereby enabling the mounting bracket 104 to achieve stable limitation.

[0031] In this embodiment, compared to the mounting bracket 104 being fixed by multiple bolts, by setting the structure of the rectangular plate 201 and the L-shaped plate 202, when cleaning the filter screen 107 and the activated carbon filter plate 109, it is only necessary to remove the cover plate 103 and then directly lift the mounting bracket 104 upward through the L-shaped plate 202, which reduces the number of bolts to be removed and makes cleaning more convenient.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
